Postoperative Opioid Usage and Disposal Strategies After Arthroscopic Procedures in a Young Cohort: A Prospective Observational Study.

Background: Although several studies have noted that patients are routinely overprescribed opioids, few have reported usage after arthroscopic surgery. Purpose: To determine opioid consumption and allocation for unused opioids after common arthroscopic surgeries. Study Design: Case series; Level of evidence, 4. Methods: Patients between the ages of 15 and 40 years who were scheduled to undergo anterior cruciate ligament reconstruction (ACLR), labral repair of the hip or shoulder, meniscectomy, or meniscal repair were prospectively enrolled. Patients were prescribed either 5 mg hydrocodone-325 mg acetaminophen or 5 mg oxycodone-325 mg acetaminophen based on surgeon preference. Patients completed a daily opioid usage survey during the 2-week postoperative period. In addition, patients completed a survey on postoperative day 21 inquiring about continued opioid use and medication disposal, if applicable. Opioid medication consumption was converted to morphine milligram equivalents (MMEs). Results: Of the 200 patients who were enrolled in the study, 176 patients had sufficient follow-up after undergoing 85 (48%) ACLR, 26 (14.8%) hip labral repair, 34 (19.3%) shoulder labral repair, 18 (10.2%) meniscectomy, and 13 (7.4%) meniscal repair procedures. Mean age was 26.1 years (SD, 7.38); surgeons prescribed a mean of 26.6 pills whereas patients reported consuming a mean of 15.5 pills. The mean MME consumption in the 14 days after each procedure was calculated: ACLR (95.7; 44% of prescription), hip labral repair (84.8; 37%), shoulder labral repair (57.2; 35%), meniscectomy (18.4; 27%), and meniscal repair (32.1; 42%). This corresponded to approximately 39% of the total opioid prescription being utilized across all procedures. Mean MME consumption was greatest on postoperative day 1 in hip, shoulder, and meniscal procedures and on postoperative day 2 in ACLR. Only 7.04% of patients reported continued opioid use in the third postoperative week. Patients had a mean of 11 unused pills or 77.7 MMEs remaining. Of the patients with remaining medication, 24.7% intended to keep their medication for future use. Conclusion: The results of our study indicate that patients who undergo the aforementioned arthroscopic procedures consume <75 MMEs in the 2-week postoperative period, translating into a mean of 10 to 15 pills consumed. Approximately 60% of total opioids prescribed went unused, and one-fourth of patients intended to keep their remaining medication for future usage. We have provided general prescribing guidelines and recommend that surgeons carefully consider customizing their opioid prescriptions on the basis of procedure site to balance optimal postoperative analgesia with avoidance of dissemination of excess opioids.

Using Oswestry Disability Index as a Preoperative Surgical Eligibility Criterion for Patients Requiring Lumbar Fusion for Degenerative Lumbar Spine Disease.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To evaluate how preoperative Oswestry Disability Index (ODI) thresholds might affect minimal clinically important difference (MCID) achievement following lumbar fusion. SUMMARY OF BACKGROUND DATA: As payers invest in alternative payment models, some are suggesting threshold cutoffs of patient reported outcomes (PROMs) in reimbursement approvals for orthopedic procedures. The feasibility of this has not been investigated in spine surgery. MATERIALS/METHODS: We included all adult patients undergoing 1-3 level primary lumbar fusion at a single urban tertiary academic center from 2014-2020. ODI was collected preoperatively and one-year postoperatively. We implemented theoretical threshold cutoffs at increments of 10. MCID was set at 14.3. The percent of patients meeting MCID were determined among patients "approved" or "denied" at each threshold. At each threshold, the positive predictive value (PPV) for MCID attainment was calculated. RESULTS: A total 1,368 patients were included and 62.4% (N=364) achieved MCID. As the ODI thresholds increased, a greater percent of patients in each group reached the MCID. At the lowest ODI threshold, 6.58% (N=90) of patients would be denied, rising to 20.2%, 39.5%, 58.4%, 79.9%, and 91.4% at ODI thresholds of 30, 40, 50, 60, and 70, respectively. The PPV increased from 0.072 among patients with ODI>20 to 0.919 at ODI>70. The number of patients denied a clinical improvement in the denied category per patient achieving the MCID increased at each threshold (ODI>20: 1.96; ODI>30: 2.40; ODI>40: 2.75; ODI>50: 3.03; ODI>60: 3.54; ODI>70: 3.75). CONCLUSION: Patients with poorer preoperative ODI are significantly more likely to achieve MCID following lumbar spine fusion at all ODI thresholds. Setting a preoperative ODI threshold for surgical eligibility will restrict access to patients who may benefit from spine fusion, despite ODI>20 demonstrating the lowest predictive value for MCID achievement.

Return to Sport After Unicompartmental Knee Arthroplasty and Patello-Femoral Arthroplasty.

BACKGROUND: Data on sports/physical activity participation following unicompartmental knee arthroplasty (UKA) and patello-femoral arthroplasty (PFA) is variable and limited. The purpose of this study was to assess participations, outcomes, and limitations in sports following UKA and PFA. METHODS: Patients who underwent UKA and PFA at a single institution from 2015 to 2020 were surveyed on sports participation before and after surgery. Data was correlated with perioperative patient characteristics and outcome scores. Among 776 patients surveyed, 356 (50%) patients responded. Of respondents, 296 (83.1%) underwent UKA, 44 (12.6%) underwent PFA, and 16 (4.5%) underwent both UKA/PFA. RESULTS: Activity participation rates were 86.5, 77.3, and 87.5% five years prior, and 70.9, 61.4, and 75% at one year prior to UKA, PFA, and UKA/PFA, respectively. Return to sports rates were 81.6, 64.7, and 62.3% at mean 4.6 years postoperatively, respectively. The most common activities were recreational walking, swimming, cycling, and golf. Patients returned to a similar participation level for low-impact activities, whereas participation decreased for intermediate- and high-impact activities. Patients participating in activities had higher postoperative Knee Injury and Osteoarthritis Outcome Score Joint Replacement (P < .001), 12-Item Short Form Physical Component Score (P = .045) and Mental Component Score (P = .012). Activity restrictions were reported among 25, 36.4, and 25% of UKA, PFA, and UKA/PFA patients, respectively, and were more commonly self-imposed than surgeon-directed. CONCLUSIONS: Though UKA patients' postoperative sports participation may improve compared to one year preoperatively, participation for patients surgically treated for isolated osteoarthritis is decreased compared to 5 years preoperatively and varies among patient subsets.

Association Between Draft Order and Stress Sonography of the Ulnar Collateral Ligament of the Elbow in Professional Baseball Pitchers: An 18-Year Study.

BACKGROUND: The Major League Baseball (MLB) draft is a common route for players to enter professional baseball in the United States. Players taken in earlier rounds are typically higher-performing players. When looking at pitchers specifically, higher performance at the amateur level may be associated with an increased frequency of adaptive change in the throwing elbow. PURPOSE: To determine whether pitchers taken in earlier rounds of the MLB draft have a greater frequency or extent of pathological change in the elbow, as measured by dynamic stress ultrasound. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: Dynamic stress ultrasounds (SUSs) were performed over 18 years on the dominant and nondominant arms of 651 professional pitchers. The 383 drafted players were grouped according to the round in which they were drafted (rounds 1-5, 6-10, 11-20, 21+). Groups were compared with respect to "relative" ulnar collateral ligament (UCL) thickness (dominant-nondominant), relative ulnohumeral joint laxity (joint space distance under stress minus joint space at rest), and the presence of pathology (calcifications, tears, hypoechoic foci, osteophytes). In addition, a subgroup analysis was done to compare the progression of SUS findings over 3 years in players for which data were available. RESULTS: Draft round groups did not differ by age, number of previous spring training, or handedness. Comparing baseline measurements, there was no significant relationship between draft round and relative UCL thickness (P = .932), relative laxity (P = .996), or presence of pathology detectable on SUS (P = .642). However, increased relative UCL thickness was significantly associated with the presence of pathology on SUS (odds ratio, 1.45; 95% CI, 1.26-1.69; P < .001). Longitudinally, there was no significant relationship between draft round and 3-year progression of relative laxity, relative UCL thickness, or clinical progression of pathology. CONCLUSION: Higher-performing pitchers are drafted earlier in the MLB draft. This may be attributable to peak pitch velocity, in-game performance, visibility gained during player showcases, or any number of other sport-specific variables. However, despite this, there was no significant relationship between draft round and adaptive changes to the elbow or specific properties of the UCL on stress ultrasound.

Mini-open Femoroacetabular Osteoplasty in Patients With Tönnis Grade 2 or Higher Osteoarthritis is Associated With a Higher Risk of Subsequent Conversion to THA.

BACKGROUND: The severity of degenerative changes of the hip is known to adversely impact the outcomes of the treatment of femoroacetabular impingement (FAI). Although the operative indications for FAI have expanded to include patients with moderate degrees of hip osteoarthritis, the exact stage of hip osteoarthritis at which surgery for FAI can offer clinical benefits is still uncertain. QUESTIONS/PURPOSES: (1) How does the survivorship free from conversion to THA and survivorship free from revision differ between patients with preexisting Tönnis Grades 2 or 3 changes and those without advanced degenerative changes (Tönnis Grade 0 or 1) after mini-open femoroacetabular osteoplasty? (2) What are the differences in hip-specific and general-health outcome scores between the two groups after mini-open femoroacetabular osteoplasty? METHODS: From December 2003 to April 2019, we treated 901 patients for FAI, and their clinical data were systematically recorded in a longitudinally maintained database. Mini-open femoroacetabular osteoplasty was our preferred surgical approach because of the surgeon's extensive experience with the technique. Among the entire dataset, 6% of patients (51 individuals) had Tönnis Grade 2 or higher hip osteoarthritis, while the remaining 94% (850 patients) had no or mild degenerative changes (Tönnis Grade 0 or 1). In the Tönnis Grade 2 or 3 group, three patients were lost before the minimum 2-year follow-up duration, leaving 4% (48 patients) who qualified for inclusion in the study. For the matched group with Tönnis Grade 0 or 1, 5% (45 patients) were excluded because of incomplete data, and a further 7% (58 patients) were excluded because they did not have 2 years of follow-up, leaving 83% (747 patients) who were eligible for the matching process. Matching was based on patient age (within 1 year), gender, and BMI (within one unit). Matching resulted in the inclusion of 144 randomly selected control patients in this retrospective, comparative study. General indications for femoroacetabular osteoplasty included symptoms of pain and restricted hip motion in young, active patients with signs of FAI evident on physical examination and radiographs. Patient demographics, medical history, radiographic parameters, and intraoperative findings were compared between the two groups to establish baseline differences and identify potential confounding variables. There was no difference in the mean ± standard deviation age between the cohort of interest and control group (39 ± 10 years and 38 ± 11 years, respectively; p = 0.67). There was no difference in the mean follow-up duration (7 ± 3 years versus 8 ± 2 years; p = 0.25) or the preoperative symptomatic period between the study and control groups (2 ± 2 years versus 3 ± 6 years; p = 0.09). There was no difference in the prevalence of dysplasia, slipped capital femoral epiphysis, Perthes disease, or avascular necrosis of the hip between the two groups. Intraoperatively, the groups did not differ in terms of labral repair (65% [31 of 48] versus 78% [113 of 144]; p = 0.08) and labral transplantation (2%; p > 0.99 for both); however, labral resection was performed more frequently in the study group (63% [30 of 48] versus 42% [60 of 144]; p = 0.002). At a minimum of 2 years of follow-up, survivorship free from conversion to THA and survivorship free from revision surgeries, as well as the latest clinical and functional outcome scores (SF-36, Hip Disability and Osteoarthritis Outcome Score, and modified Harris hip score), were compared between groups. RESULTS: Survivorship free from conversion to THA at 5 years was lower among patients with preexisting Tönnis Grades 2 or 3 changes than it was among patients matched for age, gender, and BMI who did not have advanced degenerative changes (Tönnis Grade 0 or 1) after mini-open femoroacetabular osteoplasty (75% [95% confidence interval 64% to 88%] versus 92% [95% CI 87% to 96%]; p < 0.001). No patients in either group underwent reoperation other than conversion to THA. Although the groups did not differ at baseline in terms of their outcomes scores, the group with more visible arthritis had lower postoperative Hip Disability and Osteoarthritis Outcome Scores than the control group (60 ± 21 points versus 86 ± 11 points, mean difference 26 points [95% CI 10 to 41]; p =0.004). There were no other between-group differences in outcome scores after surgery. CONCLUSION: In our study, approximately 25% of patients undergoing mini-open femoroacetabular osteoplasty with Tönnis Grade 2 or higher osteoarthritis underwent conversion to THA within 5 years. Some postoperative functional scores were lower in patients with advanced arthritis than in matched patients with no or mild arthritis. We emphasize the importance of exercising caution when considering femoroacetabular osteoplasty in patients in whom advanced arthritis is already evident at the time of presentation. LEVEL OF EVIDENCE: Level III, therapeutic study.

Joint line position change in primary total knee arthroplasty: a radiographic analysis comparing conventional and robotic techniques.

PURPOSE: Joint line (JL) position change in total knee arthroplasty (TKA) may alter knee biomechanics and impact function. The purpose of this study was to compare the change in JL position between robotic-assisted TKA (RA-TKA) and conventional TKA (C-TKA). METHODS: A retrospective, radiographic analysis was conducted of patients who underwent RA-TKA and C-TKA to compare JL position change. JL position was measured in consecutive RA-TKAs and C-TKAs performed by four fellowship-trained arthroplasty surgeons. Statistical analysis was done utilizing t-tests and Mann Whitney U tests, with statistical significance being defined as a p value < 0.05. RESULTS: Six hundred total RA-TKAs and 400 total C-TKAs were included in the analysis. There were no significant differences in patient baseline characteristics such as body mass index, range of motion, and tibiofemoral coronal alignment. RA-TKAs were associated with an average of 0.04 (2.2) mm JL position change, and C-TKAs were associated with an average 0.5 (3.2) mm JL position change (p = 0.030). There were inter-surgeon differences when comparing the change in JL position for RA-TKAs and C-TKAs between the four participating surgeons. CONCLUSION: RA-TKA leads to better preservation of the JL position than C-TKA, and this seems to be dependent on the arthroplasty surgeon's preferences and techniques during TKA. Whether this statistically significant difference is clinically relevant needs to be further investigated.

Trigger Finger Release: Are Sutures Requiring Removal Necessary?

Purpose: There is no consensus regarding optimal closure for trigger finger release (TFR) surgery. The purpose of this study was to compare the number of postoperative visits and complications following TFR closure with nonabsorbable sutures versus those following TFR closure with absorbable sutures and skin glue. The hypothesis was that wound closure with absorbable sutures and glue will result in fewer postoperative visits, while having similar complication rates as that with nonabsorbable sutures. Methods: A retrospective review identified all patients undergoing open TFR over a 3-year period performed by two hand surgery fellowship-trained hand surgeons who adhered to an identical surgical protocol except for incisional closure. Patients were divided into two groups: a control group with nonabsorbable 4-0 monofilament sutures requiring removal ("suture" group) and a study group with buried absorbable 4-0 monofilament sutures not requiring removal as well as skin glue ("glue" group). The data collected included age, sex, number of postoperative visits, wound complications, infections, antibiotic use, prescribed hand therapy, hospital admission, and reoperation. Results: A total of 305 open TFR surgeries in 278 patients were included in the study, with 155 digits in the "suture" group and 150 in the "glue" group. Both groups were similar in age and sex. The "suture" group had significantly more total postoperative visits (185 vs 42, respectively, P < .001) and postoperative visits within the first 2 weeks (155 vs 10, respectively, P < .001) than the "glue" group. Additional postoperative visits beyond 2 weeks of surgery were similar between the two groups. Three (1.9%) patients in the "suture" group and two (1.3%) patients in the "glue" group developed a superficial surgical site infection within 30 days after surgery. Neither had deep infections requiring hospitalization or reoperation. Both groups required similar rates of postoperative hand therapy. Conclusions: Absorbable sutures afford fewer postoperative visits while having a similar complication rate as nonabsorbable sutures requiring removal. Type of study/level of evidence: Therapeutic IV.

Distressed communities demonstrate increased readmission and health care utilization following shoulder arthroplasty.

BACKGROUND: Socioeconomic status (SES) has been shown to affect outcomes following total shoulder arthroplasty (TSA), but little is known regarding how SES and the communities in which patients reside can affect postoperative health care utilization. With the growing use of bundled payment models, understanding what factors put patients at risk for readmission and the ways in which patients utilize the health care system postoperatively is crucial for preventing excess costs for providers. This study helps surgeons predict which patients are high-risk and may require additional surveillance following shoulder arthroplasty. METHODS: A retrospective review of 6170 patients undergoing primary shoulder arthroplasty (anatomic and reverse; Current Procedural Terminology code 23472) from 2014-2020 at a single academic institution was performed. Exclusion criteria included arthroplasty for fracture, active malignancy, and revision arthroplasty. Demographics, patient zip code, and Charlson Comorbidity Index were attained. Patients were classified according to the Distressed Communities Index (DCI) score of their zip code. The DCI combines several metrics of socioeconomic well-being to generate a single score. Zip codes are then classified by scores into 5 categories based on national quintiles. The primary outcome of interest was 90-day readmissions. Secondary outcomes included number of postoperative medication prescriptions, patient telephone calls to the office, and follow-up office visits. RESULTS: Among all patients undergoing total shoulder arthroplasty, individuals from distressed communities were more likely than their prosperous counterparts to experience an unplanned readmission (odds ratio = 1.77, P = .045). Patients from comfortable (relative risk [RR] = 1.12, P < .001), midtier (RR = 1.13, P < .001), at-risk (RR = 1.20, P < .001), and distressed (RR = 1.17, P < .001) communities were all more likely to use more medications compared to those from prosperous communities. Likewise, those from comfortable (RR = 0.92, P < .001), midtier (RR = 0.88, P < .001), at-risk (RR = 0.93, P = .008), and distressed (RR = 0.93, P = .033) communities, respectively, were at a lower risk of making calls compared to prosperous communities. CONCLUSIONS: Following primary total shoulder arthroplasty, patients who reside in distressed communities are at significantly increased risk of experiencing an unplanned readmission and increased health care utilization postoperatively. This study revealed that patient socioeconomic distress is more associated with readmission than race following TSA. Increased awareness and employing strategies to maintain and ultimately improve communication with patients offers a potential solution to reduce excessive health care utilization, benefiting both patients and providers alike.

Hyponatremia Is an Overlooked Sign of Trouble Following Total Joint Arthroplasty.

BACKGROUND: Hyponatremia is a common electrolyte abnormality in arthroplasty patients. This issue, underrecognized by surgeons, can impact the postoperative course of patients. There are, however, little data on the implications of sodium disturbances following total joint arthroplasty (TJA). The primary aims of this study were to (1) report the rate of hyponatremia following TJA, and (2) examine the impact of hyponatremia on the perioperative course of TJA patients. METHODS: This was a retrospective analysis of 3,071 primary and revision TJAs performed between 2015 and 2017. Based on preoperative and postoperative sodium values (pre-post), patients were classified into 4 groups: normonatremic-normonatremic (Group 1), normonatremic-hyponatremic (Group 2), hyponatremic-normonatremic (Group 3), and hyponatremic-hyponatremic (Group 4). Primary end points were length of stay (LOS), postoperative discharge, in-hospital complications, and 90-day readmissions. RESULTS: The distribution of cases was 84.6% Group 1, 9.4% Group 2, 2.1% Group 3, and 3.8% Group 4. Overall, 13.2% of patients had hyponatremia after TJA. Older age, hip arthroplasty, general anesthesia, higher Charlson Comorbidity Index, congestive heart failure, revision surgery, and history of stroke, liver disease, and chronic kidney disease were risk factors for postoperative hyponatremia. Patients with postoperative hyponatremia (Groups 2 and 4) had greater likelihoods of having a 90-day complication and non-home discharge and greater LOS. CONCLUSIONS: Postoperative hyponatremia was a relatively common occurrence in patients undergoing TJA, and was associated with greater LOS, complications, and non-home discharge. Surgeons should identify patients at risk for developing sodium abnormalities in order to optimize these patients and avoid increased resource utilization. LEVEL OF EVIDENCE: Prognostic Level III .

Mortality and Complications Following Early Conversion Arthroplasty for Failed Hip Fracture Surgery.

BACKGROUND: Hip fracture in older patients leads to high morbidity and mortality. Patients who are treated surgically but fail acutely face a more complex operation with conversion total hip arthroplasty (THA). This study investigated mortalities and complications in patients who experienced failure within one year following hip fracture surgery requiring conversion THA. METHODS: Patients aged 60 years or more undergoing conversion THA within one year following intertrochanteric or femoral neck fracture were identified and propensity-matched to patients sustaining hip fractures treated surgically but not requiring conversion within the first year. Patients who had two-year follow-up (91 conversions; 247 comparisons) were analyzed for 6-month, 12-month, and 24-month mortalities, 90-day readmissions, surgical complications, and medical complications. RESULTS: Nonunion and screw cutout were the most common indications for conversion THA. Mortalities were similar between groups at 6 months (7.7% conversion versus 6.1% nonconversion, P = .774), 12 months (11% conversion versus 12% nonconversion, P = .999), and 24 months (14% conversion versus 22% nonconversion, P = .163). Survivorships were similar between groups for the entire cohort and by fracture type. Conversion THA had a higher rate of 90-day readmissions (14% versus 3.2%, P = .001), and medical complications (17% versus 6.1%, P = .006). Inpatient and 90-day orthopaedic complications were similar. CONCLUSION: Conversion THA for failed hip fracture surgery had comparable mortality rates to hip fracture surgery, with higher rates of perioperative medical complications and readmissions. Conversion THA following hip fracture represents a potential "second hit" that both surgeons and patients should be aware of with initial decision-making.

Do Patient Outcomes Predict Loss to Long-Term Follow-Up After Spine Surgery?

OBJECTIVE: To determine if spine surgery patients with greater improvement in patient-reported outcomes measures (PROMs) at early postoperative follow-up are more likely to be lost to follow-up at the 1-year and 2-year postoperative visits. METHODS: All patients older than 18 years who underwent primary or revision decompression or fusion surgery for degenerative spinal conditions at an academic institution were retrospectively identified. Univariate analysis compared patient demographics, surgical factors, and changes in short-term and long-term postoperative PROMs (Neck Disability Index, Oswestry Disability Index, visual analog scale [VAS] neck, VAS arm, VAS back, VAS leg, and Short-Form 12 Physical and Mental Component Scores) across groups with and without 1 year and 2 years follow-up. Logistic regression isolated predictors of loss to follow-up. RESULTS: A total of 1412 patients were included. Younger patient age, primary surgery, and single surgical approach independently predicted loss at 1 year follow-up. Female sex predicted loss at 2 years follow-up, whereas multilevel fusion surgery predicted attendance at 2 years clinical follow-up. In patients lost at 1 year follow-up compared with those who attended, preoperative to 3-month Mental Component Score and VAS neck pain improvement was significantly greater. When comparing patients based on 2 years follow-up status, VAS back pain improvement at 1 year postoperatively was significantly greater in patients lost to 2 years follow-up. All other changes in PROMs did not differ significantly by 1 or 2 years follow-up attendance. CONCLUSIONS: Overall patient outcomes were not found to affect loss to long-term follow-up after spine surgery. The general lack of association between postoperative follow-up status and clinical outcome may limit bias introduced in retrospective PROM studies.

Routine Use of Closed Suction Drains Following Revision Arthroplasty May Not be Necessary.

BACKGROUND: There are numerous studies demonstrating that closed suction drainage (CSD) usage after primary total joint arthroplasty (TJA) has little to no benefit. There are little data on the role of CSDs after revision TJA. The purpose of our study was to evaluate whether there is any clinical advantage to CSD usage after revision TJA. METHODS: This retrospective study evaluated the clinical records of 2,030 patients undergoing revision TJA between 2007 and 2021. CSD was used in 472 patients and not used in 1,558 patients. Primary outcome was blood transfusion rate and secondary outcomes included total blood loss (TBL), as determined by Gross formula, wound complications (hematoma, infection, and dehiscence), and length of hospital stay. Patients undergoing revision TJA for oncologic reasons or those with incomplete datasets were excluded. RESULTS: There were no statistically significant differences in rates of allogeneic blood transfusion, TBL, and wound complications (hematoma, infection, and dehiscence) between the two groups (P = .159, .983, .192, .334, and .548, respectively). When adjusted for demographic and surgical confounders, there was no difference in transfusion and TBL rates between groups (Odds Ratio 1.04, 95% Confidence Interval 0.78-1.38, P = .780 and estimate -105.71 mL, 95% confidence interval -333.96 to 122.55, P = .364, respectively). CSD cohort had a shorter length of stay (4.30 versus 5.82 days, P < .001). CONCLUSION: We acknowledge that there is a role for CSD usage in a selected group of patients. Nevertheless, our study revealed that routine use of CSD after revision TJA does not provide an additional clinical benefit.

Comprehensive Analysis of Opioid Use After Common Elective Outpatient Orthopaedic Surgeries.

BACKGROUND: Prescription opioid abuse remains an ongoing public health crisis, especially in orthopaedic surgery. The purpose of the present study is to analyze opioid-prescribing patterns and investigate risk factors for prolonged opioid use after common outpatient orthopaedic surgical procedures. METHODS: After institutional review board approval, a review of 1,384 patients undergoing common elective outpatient orthopaedic procedures from January 2018 to June 2019 was conducted. Data on controlled substance prescriptions were obtained from the prescription drug monitoring program website. Statistical analysis was done to identify predictors for a second opioid prescription and prolonged opioid use (>6 months). RESULTS: Over 10% (150/1,384) of patients were still using opioids beyond 6 months. Of the opioid exposed patients, 60.4% (174/288) filled at least 1 additional opioid prescription postoperatively, and 29.2% (84/288) filled prescriptions beyond 6 months, compared with 26.4% (289/1,096) and 6.0% (66/1,096) of opioid-naive patients, respectively. Following multivariate analysis, significant predictors for filling a second opioid prescription included preoperative opioid use, current smoker status, benzodiazepine use, psychiatric disorder, and advanced age. CONCLUSION: This study revealed risk factors for prolonged opioid use after orthopaedic surgery. Surgeons should be mindful of these risk factors and counsel patients regarding postoperative pain management.

Cumulative Intraarticular Injections Are Not a Risk Factor for Periprosthetic Joint Infection Following total Knee Arthroplasty.

BACKGROUND: While injections within 90 days prior to total knee arthroplasty (TKA) are associated with an increased risk of periprosthetic joint infection (PJI), there is a paucity of literature regarding the impact of cumulative injections on PJI risk. This study was conducted to assess the association between cumulative corticosteroid and hyaluronic acid (HA) injections and PJI risk following TKA. METHODS: This retrospective study using an injection database included patients undergoing TKA with a minimum 1-year follow-up from 2015 to 2020. Patients with injections within 90 days prior to surgery were excluded. The sum of corticosteroid and HA injections within five years prior to TKA was recorded. The primary outcome was PJI within 90 days following TKA. Area under the curve (AUC) values were calculated for a cumulative number of injections. RESULTS: 648 knees with no injections and 672 knees with injections prior to TKA were included, among whom 243 received corticosteroids, 151 received HA, and 278 received both. No significant differences in early PJI rates existed between patients who received injections (0.60%) or not (0.93%) (P = .541). No significant differences existed in early PJI rates between patients injected with corticosteroids (0.82%), HA (0.66%), or both (0.36%) (P = .832). No cutoff number of injections was predictive for PJI. DISCUSSION: A cumulative amount of steroid or HA injections, if given more than 90 days prior to TKA, does not appear to increase the risk of PJI within 90 days postoperatively. Multiple intraarticular corticosteroid injections and HA injections may be safely administered before TKA, without increased risk for early PJI.

The Incidence of Adjacent Segment Pathology After Cervical Disc Arthroplasty Compared with Anterior Cervical Discectomy and Fusion: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

OBJECTIVE: The aim of this study was to assess rates of adjacent segment degeneration (ASDeg), adjacent segment disease (ASDis), and reoperation rates as a result of adjacent segment pathology in patients who have undergone anterior cervical discectomy and fusion (ACDF) versus cervical disc arthroplasty (CDA). METHODS: A comprehensive search of randomized controlled trials was performed in PubMed from 2012 to 2019. Relevant studies included were assessed for quality using the Cochrane Beck Review Group guidelines. Rates of ASDeg, ASDis, and reoperation because of adjacent segment pathology were extracted and included in the final analysis. A random-effects and fixed-effects model was run among studies that showed high and low heterogeneity, respectively. RESULTS: A total of 19 studies were included in the final analysis, comprising 4655 patients. Overall, ACDFs reported significantly higher rates of ASDeg (19.7% vs. 14.4%; P < 0.001), ASDis (6.1% vs. 3.8%; P < 0.001), and reoperation rates (6.1% vs. 3.1%; P < 0.001) compared with CDAs, which was further corroborated in fixed-effects analysis. When stratified by length of follow-up, a significant difference was seen in ASDeg, ASDis, and reoperation rates of studies with follow-up of 12-48 months versus >48 months, with the exception of ASDeg rates in the CDA cohort. CONCLUSIONS: Our study shows CDA results in significantly lower ASDeg, ASDis, and reoperation rates. Although CDA may be a viable alternative to ACDF, further long-term studies are warranted to ensure consistency and establish longevity of our findings.

Inflammatory Bowel Diseases Increase the Risk of Periprosthetic Joint Infection.

BACKGROUND: A large body of evidence is emerging to implicate that dysregulation of the gut microbiome (dysbiosis) increases the risk of surgical site infections. Gut dysbiosis is known to occur in patients with inflammatory bowel disease (IBD), allowing for translocation of bacteria across the inflamed and highly permeable intestinal mucosal wall. The null hypothesis was that IBD was not associated with an increased risk of periprosthetic joint infection (PJI) after primary total hip and knee arthroplasty. METHODS: A matched cohort study was designed. The primary end point was the occurrence of PJI at 2 years postoperatively. The secondary end points were aseptic revisions at 2 years postoperatively, discharge to a rehabilitation facility, complications up to 30 days after total joint arthroplasty, and readmission up to 90 days after total joint arthroplasty. The International Classification of Diseases, Ninth Revision (ICD-9) and Tenth Revision (ICD-10) codes were used to identify patients with IBD and the control cohort. A chart review was performed to confirm the diagnosis of IBD. Using our institutional database, 152 patients with IBD were identified and matched (3:1) for age, sex, body mass index, year of surgical procedure, Charlson Comorbidity Index, and involved joint with 456 patients without IBD undergoing total joint arthroplasty. RESULTS: The cumulative incidence of PJI was 4.61% for the patients with IBD compared with 0.88% for the control cohort (p = 0.0024). When univariable Cox regression was performed, a diagnosis of IBD was found to be an independent risk factor for PJI (hazard ratio [HR], 5.44 [95% confidence interval (CI), 1.59 to 18.60]; p = 0.007) and aseptic revisions (HR, 4.02 [95% CI, 1.50 to 10.79]; p = 0.006). The rate of postoperative complications was also higher in patients with IBD. CONCLUSIONS: Based on the findings of this study, it appears that patients with IBD are at higher risk for treatment failure due to PJI or aseptic loosening after primary total joint arthroplasty. The exact reason for this finding is not known, but could be related to bacterial translocation from the inflamed intestinal mucosa, the dysregulated inflammatory status of these patients, malnutrition, and potentially other factors. Some of the aseptic failures could be as a result of infection that may have escaped detection and/or recognition. LEVEL OF EVIDENCE: Prognostic Level III.

Larger Perioperative Opioid Prescriptions Lead to Prolonged Opioid Use After Hand and Upper Extremity Surgery: A Multicenter Analysis.

INTRODUCTION: The opioid epidemic remains an ongoing public health crisis. The purpose of this study was to investigate whether surgeons' prescribing patterns of the initial postoperative opioid prescription predispose patients to prolonged opioid use after upper extremity surgery. METHODS: This multicenter retrospective study was done at three academic institutions. Patients who underwent carpal tunnel release, basal joint arthroplasty, and distal radius fracture open reduction and internal fixation over a 1.5-year period were included. Opioid prescription data were obtained from the Pennsylvania Prescription Drug Monitoring Program website. RESULTS: Postoperatively, 30.1% of the patients (191/634) filled ≥1 additional opioid prescription, and 14.0% (89/634) experienced prolonged opioid use 3 to 6 months postoperatively. Patients who filled an additional prescription postoperatively were initially prescribed significantly more pills (P = 0.001), a significantly longer duration prescription (P = 0.009), and a significantly larger prescription in total milligram morphine equivalents (P = 0.002) than patients who did not fill additional prescriptions. Patients who had prolonged opioid use were prescribed a significantly longer duration prescription (P = 0.026) than those without prolonged use. CONCLUSION: Larger and longer duration of initial opioid prescriptions predisposed patients to continued postoperative opioid use. These findings emphasize the importance of safe and evidence-based prescribing practices to prevent the detrimental effects of opioid use after orthopaedic surgery.

Short Interval Staged Bilateral Total Knee Arthroplasty: Safety Compared to Simultaneous and Later Staged Bilateral Total Knee Arthroplasty.

BACKGROUND: Simultaneous bilateral total knee arthroplasty (sim-BTKA) is reported to be safe in a select group of patients. Patients with symptomatic bilateral knee arthritis who are not candidates for sim-BTKA require staged surgery (stag-BTKA). This study aimed to compare the safety and complications associated with sim-BTKA with stag-BTKA performed at 2 time intervals. METHODS: This retrospective study of prospectively collected data includes bilateral TKA cases performed between 2001 and 2019. A cohort of sim-BTKA (n = 2728) was compared to a cohort of stag-BTKA (n = 1658). The staged group was subdivided according to the interval between surgeries: ≤90 days (early) and ≥91 days (later). Multivariate logistic regression analyses were used to adjust for confounding variables. RESULTS: In-hospital complication rates were lower in both arms of the stag-BTKA groups vs the sim-BTKA. The sim-BTKA group had higher odds ratio of anemia, electrolyte disturbances, pulmonary embolism, and respiratory, urinary, gastrointestinal, and neurological complications. Lower rates of all-cause revision were found in stag-BTKA vs sim-BTKA groups. There was a trend toward revision due to deep infection when increasing the interim before the second stag-BTKA procedure. No differences in complication rates after the second surgery were detected between the early and later stag-BTKA. CONCLUSION: This study demonstrates that sim-BTKA is associated with more complications and revisions when compared to stag-BTKA. Performing the second-stage TKA at 90 days or less after the first TKA is not associated with increased risk of complications. Performing sim-BTKA, simply for convenience, is not warranted and should be reserved for a select group of patient matching specific criteria.

Is Open Surgery for Metastatic Spinal Cord Compression Secondary to Lung Cancer Really Beneficial? A Systematic Review.

OBJECTIVE: Spinal cord compression secondary to metastatic epidural lung cancer generally has a worse prognosis when compared with other metastatic tumors. The purpose of this study was to determine the impact of open surgery on the survival time, ambulation status, and associated prognostic variables of these patients over the past 2 decades. METHODS: We searched the PubMed, MEDLINE, and CENTRAL databases to identify patients with spinal cord compression secondary to metastatic lung cancer. We assessed the role of the following factors on survival outcome and ambulation recovery: Karnofsky Performance Scale, number of extraspinal bone metastases, number of metastases in the vertebrae, major internal organs involvement, vertebral location of spinal metastases, and neurologic status. RESULTS: Our initial search yielded 367 articles, from which 11 studies met the eligibility criteria for a total of 395 patients. Significant correlations with the survival period and the recovery in ambulation were found in the prognostic score for the number of metastases in vertebrae (R = 0.74 and 0.88, respectively), and in the prognostic score for metastases to major internal organs (R = 0.82 and 0.81, respectively). A significant correlation with survival period was found in the numbers of extraspinal bone metastases (R = -0.82). The rates of major complications were comparable with those for open surgery for metastatic tumors of other origin. CONCLUSIONS: Fewer vertebral metastases and less major internal organ involvement were associated with longer survival periods and greater ambulation recovery in patients undergoing open surgery for spinal cord compression secondary to metastatic lung cancer.

Periprosthetic Joint Infection in Patients Who Have Multiple Prostheses in Place: What Should Be Done with the Silent Prosthetic Joints.

BACKGROUND: Although periprosthetic joint infection (PJI) can affect multiple joints concurrently, the majority of patients with multiple prosthetic joints present with PJI of a single joint. Data regarding the optimal management of these patients are limited. We aimed to identify the prevalence, risk factors for a subsequent PJI, and clinical circumstances of PJI in patients with multiple prosthetic joints. METHODS: We retrospectively reviewed the clinical records of 197 patients with ≥2 total joint prostheses in place who presented with PJI from 2000 to 2017. The average follow-up was 3.6 years (range, 0.5 to 17 years). Demographic data and risk factors for synchronous or metachronous PJI were identified. The time from the initial to the second PJI and organism profile data were collected as well. The workup for other joints with a prosthesis in place at the time of the initial PJI was noted. RESULTS: Among the 197 patients with PJI and multiple joint prostheses in situ, 37 (19%) developed PJI in another joint; 11 had a synchronous PJI and 26 had a metachronous PJI. The average time between the first and the second infection in the metachronous cases was 848 days (range, 20 to 3,656 days). Females and patients with an initial PJI with methicillin-resistant Staphylococcus aureus (MRSA) were more likely to have a metachronous PJI, and patients with rheumatoid arthritis had an increased risk of a second (metachronous or synchronous) PJI. Three of 11 patients in the synchronous group and 19% (5) of the 26 in the metachronous group had bacteremia at the time of the initial PJI compared with 12% (19) of the 160 with a single PJI. The percentage of negative cultures increased from 10% for the initial PJIs to 38% for the metachronous PJIs. CONCLUSIONS: Patients who have multiple prosthetic joints in place and present with PJI of a single joint are at risk of developing PJI in another joint. Female sex, rheumatoid arthritis, bacteremia at presentation, and infection with MRSA appear to be risk factors for PJI of another joint. Clinical evaluation of the other prosthetic joint(s) should be carried out in all patients and aspiration of those joint(s) should be considered for patients with any of the above risk factors.
