ABSTRACT
Purpose: To determine the relationship between meniscus tear morphologies, stratified by location and pattern, and knee arthroplasty rates in a commercial insurance population. Methods: The PearlDiver database was queried for patients ≥35 years old with a meniscus tear of specified laterality and ≥2 years follow-up between 2015 and 2018. Two analyses were conducted with cohorts matched on age, sex, Charlson Comorbidity Index, obesity, osteoarthritis (OA), and treatment (meniscectomy vs conservative): one with equal-sized subgroups by tear location (medial only, lateral only, or both medial and lateral) and another by tear pattern (bucket-handle, complex, or peripheral). The rate of subsequent total knee arthroplasty (TKA) was compared between matched groups. Results: In total, 129,987 patients (mean age: 57.8 ± 10.5 years) were matched by tear location; 1,734 patients with medial-only tears (4.0%), 1,786 with lateral-only tears (4.1%), and 2,611 with medial plus lateral tears (6.0%) underwent a TKA within 5 years (P < .001). Patients with both medial and lateral tears were 1.55-fold more likely to undergo TKA. In total, 24,213 patients (mean age: 56.0 ± 10.5 years) were matched by tear pattern; 296 patients with bucket-handle tears (3.7%), 373 with complex tears (4.6%), and 336 with peripheral tears (4.2%) underwent TKA (P = .01). Patients with complex tears were 1.29-fold more likely to undergo TKA than patients with bucket-handle tears (P = .002). Conclusions: In matched cohorts of patients with degenerative meniscus tears, having both medial plus lateral tears conferred a 1.5-fold risk of TKA, whereas complex tears conferred a 1.3-fold risk within 5 years. Specific meniscal tear patterns and locations harbor varying risk in progressing to end-stage knee OA, and these data may help counsel patients about their likelihood of progressing to end-stage OA warranting an arthroplasty procedure. Level of Evidence: Level III, retrospective comparative study.
ABSTRACT
BACKGROUND: The aim of this study was to reevaluate patients from a previous randomized controlled trial at a long-term follow-up to determine the long-term efficacy of subacromial decompression in patients with full-thickness rotator cuff tears. METHODS: This is a secondary study based on a previous, multicenter, randomized controlled trial with patients allocated to arthroscopic rotator cuff repair with or without acromioplasty. The original study was conducted between 2003 and 2011, and the secondary study was conducted between 2015 and 2021. Patients were invited by a blinded assessor to return to complete the Western Ontario Rotator Cuff (WORC) index and a questionnaire about reoperation and to undergo a clinical assessment. If participants were unable to return, they were asked to complete the questionnaires by mail. A chart review on all participants in the original study was conducted. RESULTS: Eighty-six patients were randomized in the original trial, with 31 of 45 from the group without acromioplasty and 25 of 41 from the acromioplasty group returning for long-term follow-up. The mean duration (and standard deviation) of follow-up was 11.2 ± 2.4 years for the group without acromioplasty and 11.5 ± 2.6 years for the acromioplasty group. There was no significant difference in WORC scores between the groups with and without acromioplasty at the time of the long-term follow-up (p = 0.30). Seven (16%) of the 45 patients in the group without acromioplasty underwent reoperation. One (2%) of the initial 41 patients allocated to acromioplasty underwent reoperation. All patients who underwent a reoperation had a Type-2 or 3 acromion. CONCLUSIONS: Patients who underwent rotator cuff repair with or without acromioplasty experienced improvement of outcomes from their preoperative level at a long-term follow-up (mean, 11 years), and there were no differences in patient-reported outcomes, specifically WORC scores, between these groups. However, a significantly higher reoperation rate was observed in patients who had rotator cuff repair without acromioplasty, specifically in those with a Type-2 or 3 acromion.

Purpose: To compare the early postoperative outcomes of patients undergoing inpatient versus outpatient hip arthroscopy and identify any characteristics that may serve as predictors of these complications. Methods: The PearlDiver Mariner insurance database was queried for all patients who underwent hip arthroscopy from 2010 to 2019. Patients were matched based on Charlson Comorbidity Index, age, and sex. Outcomes recorded included postoperative complications and return to care within 90 days. Predictors of complications were assessed via multivariable logistic regression controlling for age, sex, Charlson Comorbidity Index, comorbidities, surgical setting, and procedure type. Results: The final matched cohort included 832 inpatients and 1,356 matched patients. Fifty-eight patients (7.0%) who underwent inpatient surgery versus 25 patients (1.8%) who underwent outpatient surgery were readmitted (P < .01). Of the readmitted patients, 31 inpatients (3.7%) and 5 outpatients (0.4%) were readmitted for hip-related reasons (P < .01). No significant differences were observed in emergency department visits (67 inpatients [8.1%] vs 84 outpatients [6.2%], P = .11), intensive care unit admissions (3 [0.4%] vs 1 [0.1%], P = .31), or revision hip arthroscopies (43 [5.2%] vs 65 [4.8%], P = .77). A multivariable model of complications correcting for baseline differences in chronic obstructive pulmonary disease, coronary artery disease, diabetes, hypertension, ischemic heart disease, tobacco use, and inpatient status found that age (adjusted odds ratio [OR], 0.92; 95% confidence interval [CI], 0.85-0.99; P = .03), coronary artery disease (adjusted OR, 12.82; 95% CI, 1.18-140.02; P = .03), and inpatient setting (adjusted OR, 20.59; 95% CI, 3.48-401.65; P = .01) were significantly associated with complications. No procedure type was associated with complication rates. Conclusions: Compared with the outpatient setting, inpatient hip arthroscopy is associated with higher rates of readmission in a cohort matched for age, sex, and comorbidities. Complications after inpatient hip arthroscopy appear to be related to comorbidities rather than procedure-related factors. The decision to conduct an inpatient hip arthroscopy should prioritize consideration of patient comorbidities over the type of procedure. Level of Evidence: Level III, retrospective cohort study.
ABSTRACT
PURPOSE: Consensus guidelines recommend administering a corticosteroid injection (CSI) for patients with a symptomatic degenerative meniscus lesion prior to arthroscopic partial meniscectomy (APM). A recent study found that CSI administered within 1 month prior to meniscectomy is associated with an increased risk of postoperative infection. However, infections may range in severity from superficial infections to serious infections requiring surgical interventions. The aim of this analysis was to define the rate of infections requiring surgery after APM and determine its relationship to preoperative CSI. METHODS: The PearlDiver Mariner administrative claims database was queried for patients > 35 years old who had a CSI in the year prior to isolated APM. Rates of deep infection and infection requiring surgery within 6 months were reported between matched patients with a CSI and no injection. RESULTS: After matching, there were 16,009 patients per group with a mean age of 59.4 years (SD = 9.6), 53.5% obesity, and 40% male. Forty-four of 113 patients who developed a postoperative deep infection went on to have a reoperation for irrigation and/or debridement (0.1% of all APM). Of these 44 patients, 30 had a preoperative CSI and 14 were controls unadjusted odds ratio (unadj-OR) if given CSI = 1.95, 95% CI 1.03-3.68, P = 0.04). Having a CSI within the month before surgery conferred a 4.56-fold increase in odds of an infection warranting surgery (95% CI 1.96-10.21, P < 0.01), whilst having a CSI 4-8 weeks before surgery conferred a 2.42-fold increase in odds (95% CI 1.04-5.42, P = 0.03). Receiving multiple CSI in the year prior to APM was associated with 5.27-fold increased odds of an infection requiring surgery (95% CI 1.19-23.27, P = 0.03), compared to having a single CSI. CONCLUSIONS: Serious infections requiring a surgical intervention are rare after a meniscectomy, occurring in 0.1% of APMs in a matched cohort of patients over 35. Patients were five times more likely to return to the operating room for infection after APM if they had a CSI in the month before or had multiple CSIs in the year before surgery. The risk of infection was no longer significant if there was at least a 2-month interval between preoperative CSI and APM. LEVEL OF EVIDENCE: Level III.

Risk for anterior cruciate ligament (ACL) injury is greater in female than in male patients for a myriad of reasons, with osseous anatomy about the knee proving to be one significant risk factor for ACL injury and/or ACL graft failure. While femoral intercondylar notch size/shape and posterior tibial slope have been well-examined in this regard for their contribution to potential ACL injury, morphology of the lateral femoral condyle is a newer entity that may be linked to risk for ACL injury. Smaller/stenotic femoral intercondylar notches, increased posterior tibial slope of the lateral tibial plateau, and increased posterior condylar depth of the lateral femoral condyle have all been shown to increase risk for ACL injury and/or ACL graft failure. Such associations provide knee surgeons with food for thought when considering procedures such as notchplasty, staged anterior closing wedge high tibial osteotomy, and anterolateral ligament reconstruction/augmentation at the time of primary or revision ACL reconstruction. Further investigation into the links between pre-operative imaging parameters and outcomes following such concomitant procedures is required in order for any significant conclusions to be drawn.

Purpose: To characterize how severe acute respiratory syndrome coronavirus 2 infection in the perioperative period affects the medical adverse event (MAE) rates in arthroscopic sports medicine procedures. Methods: The Mariner coronavirus disease 2019 (COVID-19) database was queried for all shoulder, hip, or knee arthroscopies, 2010 to 2020. Patients with COVID-19 in the 3 months before to 3 months after their surgery were matched by age, sex, and Charlson Comorbidity Index to patients with an arthroscopy but no perioperative COVID-19 infection, or a COVID-19 infection but no arthroscopic procedure. MAEs in the 3 months after surgery or illness were compared between groups. Results: The final cohort consisted of 1,299 matched patients in 3 groups: COVID-19 alone, arthroscopy and perioperative COVID-19, and arthroscopy alone. There were 265 MAEs if a patient had COVID-19 alone (20.4%), 200 MAEs if a patient had arthroscopy with COVID-19 (15.4%), and 71 (5.5%) MAEs if a patient had arthroscopy alone (P < .01). If a patient had an arthroscopy, having COVID-19 was associated with 3.1-fold elevated odds (95% confidence interval [CI] 2.9-3.4, P < .01) of MAE. Among patients with an arthroscopy, MAEs were more common if a patient acquired COVID-19 in the 3 months after their surgery (pooled odds ratio 7.39, 95% CI 5.49-9.95, P < .01) but not if a patient had preoperative COVID-19 (pooled odds ratio 0.66, 95% CI 0.42-1.03, P = .07). Conclusions: Having COVID-19 during the postoperative period appears to confer a 7-fold elevated risk of MAEs after shoulder, hip, and knee arthroscopy compared with matched patients with arthroscopy and no perioperative COVID-19 but equivalent to that of patients with COVID-19 and no arthroscopy. However, there was no increase in postoperative MAEs if a patient had COVID-19 during the 3 months preceding surgery. Therefore, it appears safe to conduct an arthroscopic procedure shortly after recovery from COVID-19 without an increase in acute medical complication rates. Level of evidence: Level III, retrospective cohort study.
ABSTRACT
BACKGROUND: The increasing incidence of anterior cruciate ligament (ACL) and meniscal injuries has led to strong interest in discovering new methods to enhance the biological healing response of these tissues. Platelet-rich plasma (PRP) contains various growth factors associated with a positive healing response, but few existing clinical studies are available to determine the risks and benefits of these therapies. PURPOSE: To determine the effects of intraoperative PRP on postoperative knee function and complications at 2 years after ACL reconstruction with meniscal repair. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A retrospective matched case-control study was conducted between 2013 and 2017 using a single surgeon database of 1014 patients undergoing primary ACL reconstruction with concomitant meniscal repair, resulting in 324 patients (162 PRP patients and 162 control patients) who met the study criteria. Patients were matched by age, sex, graft type, and meniscal injury. The Single Assessment Numeric Evaluation (SANE) was administered at 2 years, and injury surveillance was conducted. Secondary outcomes included the time to return to activity (months), self-reported knee function (International Knee Documentation Committee [IKDC] score), functional performance testing (knee range of motion, single-leg balance, single-leg hopping, agility testing), and postoperative complications (graft failure, infection, loss of motion [requiring repeat arthroscopy for lysis of adhesions], venous thrombosis, etc). Univariate models were used for between-group comparisons, and alpha was set at .05 for all analyses. RESULTS: No differences were found in SANE knee function scores between the PRP and matched-control groups at 2 years (91.6 ± 11.2 vs 92.4 ± 10.6, respectively; P = .599). Additionally, no differences were reported between groups for self-reported function (IKDC score, 87.6 ± 13.3 vs 88.1 ± 12.6; P = .952), functional performance testing (P > .05), and timing of return to activity (7.8 ± 1.9 vs 8.0 ± 1.9 months; P = .765). The PRP group demonstrated a higher rate of postoperative knee motion loss compared with the control group (13.6% vs 4.6%; P < .001). No other differences were observed in postoperative complications (P > .05). CONCLUSION: The added use of intraoperative PRP did not improve self-reported knee function, functional performance, and timing of return to activity for patients undergoing ACL reconstruction with meniscal repair. Furthermore, the use of PRP may have negative consequences for regaining knee range of motion after surgery. On the basis of these data, surgeons should cautiously consider the application of PRP when planning surgery for intra-articular injuries of the knee.

BACKGROUND: Anterior cruciate ligament (ACL) rupture is one of the most common injuries afflicting soccer players and requires a lengthy recovery processes after reconstructive surgery. The impact of ACL reconstruction (ACLR) on return to play (RTP) time and player performance in professional soccer players remains poorly studied. PURPOSE/HYPOTHESIS: To determine player performance and RTP rate and time after ACLR in elite professional soccer players with a retrospective matched-cohort analysis. We expected that the RTP time and rate will be similar to those of other professional-level athletes. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Included were 51 players from 1 of the 5 elite Union of European Football Associations (UEFA) soccer leagues who suffered a complete ACL rupture between 1999 and 2019. These athletes were matched by position, age, season of injury, seasons played, and height and compared to uninjured control players. Change in performance metrics for the 4 years after the season of injury were compared with metrics 1 season before injury. Univariate 2-group comparisons were performed using independent 2-group t tests; Wilcoxon rank-sum tests were used when normality of distributions was violated. RESULTS: Overall, 41 players (80%) returned to play after ACL rupture, with 6 (12%) experiencing a subsequent ipsilateral or contralateral ACL tear. The mean (±SD) RTP time for soccer players after ACLR was 216 ± 109 days (26 ± 18 games). Injured athletes played significantly fewer games and minutes per season and recorded inferior performances for 2 seasons after their injury (P < .001). However, the game performance of injured players equaled or exceeded that of their matched controls by season 3 after injury, with the exception of attackers, who demonstrated a continued decline in performance (P < .001). CONCLUSION: Results indicated that the mean RTP time for soccer players after ACLR is short in comparison with other major sports leagues (216 days). However, RTP rates were high, and rerupture rates were comparable with those of other sports. With the exception of attackers, player performance largely equaled or exceeded that of matched controls by the third postinjury season.
ABSTRACT
BACKGROUND: Bone marrow stimulation (BMS) via microfracture historically has been a first-line treatment for articular cartilage lesions. However, BMS has become less favorable because of resulting fibrocartilage formation. Previous studies have shown that angiogenesis blockade promotes cartilage repair. Bevacizumab is a Food and Drug Administration-approved medication used clinically to prevent angiogenesis. HYPOTHESIS: The intra-articular injection of bevacizumab would prevent angiogenesis after BMS and lead to improved cartilage repair with more hyaline-like cartilage. STUDY DESIGN: Controlled laboratory study. METHODS: The dose of bevacizumab was first optimized in a rabbit osteochondral defect model with BMS. Then, 48 rabbits (n = 8/group/time point) were divided into 3 groups: osteochondral defect (defect), osteochondral defect + BMS (BMS group), and osteochondral defect + BMS + bevacizumab intra-articular injection (bevacizumab group). Rabbits were sacrificed at either 6 or 12 weeks after surgery. Three-dimensional (3D) micro-computed tomography (microCT), macroscope score, modified O'Driscoll histology scores, collagen type 2, Herovici staining, and hematoxylin and eosin staining were performed. Angiogenesis markers were also evaluated. RESULTS: The intra-articular dose of 12.5 mg/0.5 mL bevacizumab was found to be effective without deleteriously affecting the subchondral bone. Intra-articular injection of bevacizumab resulted in significantly improved cartilage repair for the bevacizumab group compared with the BMS or the defect group based on 3D microCT, the macroscope score (both P < .05), the modified O'Driscoll histology score (P = .0034 and P = .019 vs defect and BMS groups, respectively), collagen type 2, Herovici staining, and hematoxylin and eosin staining at 6 weeks. Cartilage in the bevacizumab group had significantly more hyaline cartilage than did that in other groups. At 12 weeks, the cartilage layer regenerated in all groups; however, the bevacizumab group showed more hyaline-like morphology, as demonstrated by microCT, histology scores (P < .001 and .0225 vs defect and BMS groups, respectively), histology, and immunohistochemistry. The bevacizumab injection did not significantly change mRNA expressions of smooth muscle actin, vascular endothelial growth factor, or hypoxia-inducible factor-1 alpha. CONCLUSION: Intra-articular injection of bevacizumab significantly enhanced the quality and quantity of hyaline-like cartilage after BMS in a rabbit model. Future large-animal and human studies are necessary to evaluate the clinical effect of this therapy, which may lead to improved BMS outcomes and thus the durability of the regenerated cartilage. CLINICAL RELEVANCE: The use of bevacizumab may be an important clinical adjunct to improve BMS-mediated cartilage repair.

PURPOSE: To define the incidence of postoperative infections in patients who receive corticosteroid injections prior to arthroscopic meniscectomy, to determine whether there is a temporal relation between injections and the risk of surgical-site infections, and to identify corresponding risk factors. METHODS: The Humana administrative claims database was reviewed for patients undergoing arthroscopic meniscectomy within 1 year of injection and those undergoing arthroscopic meniscectomy without prior injection. Patients with preoperative injections were further stratified by the duration in months between the injection and the surgical procedure. Surgical-site infection within 6 months of surgery was recorded. Univariate analysis and binary logistic regression were performed to determine independent risk factors for surgical-site infection. Statistical significance was defined as P < .05. RESULTS: We identified patients with (n = 11,652) and without (n = 37,261) a history of a knee corticosteroid injection within 1 year of arthroscopic meniscectomy with at least 6 months of database activity from 2007 to 2017. In patients who received knee injections within 1 month prior to surgery, the rate of development of postoperative infections was twice that in patients who did not receive an injection (1.28% vs 0.63%; odds ratio [OR], 1.84; 95% confidence interval [CI], 1.24-2.62; P = .001). Multivariate logistic regression identified male sex (OR, 1.39; 95% CI, 1.14-1.71; P = .001), diabetes (OR, 1.48; 95% CI, 1.19-1.85; P < .001), chronic obstructive pulmonary disease (OR, 1.57; 95% CI, 1.27-1.94; P < .001), obesity (OR, 1.32; 95% CI, 1.07-1.63; P = .010), tobacco use (OR, 1.61; 95% CI, 1.30-1.98; P < .001), and preoperative injections within 1 month of surgery (OR, 1.78; 95% CI, 1.21-2.54; P = .002) as significant predictors, whereas injections administered more than 1 month before surgery were not significantly associated with postoperative surgical-site infection after arthroscopic meniscectomy. CONCLUSIONS: Injections 1 month before arthroscopic meniscectomy significantly increase the risk of surgical-site infection. However, injections can be safely administered more than 1 month prior to surgery because there is no increased risk of postoperative infection at this time point. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

BACKGROUND: The purpose of this study was to compare patient-reported and clinic outcomes between arthroscopic Bankart repair with (REMP) and without (NO REMP) arthroscopic infraspinatus remplissage in patients with recurrent anterior shoulder instability with a Hill-Sachs lesion and minimal glenoid bone loss. METHODS: Patients 14 years or older with a recurrent anterior shoulder instability with the presence of an engaging Hill-Sachs defect (of any size) confirmed on computed tomography or magnetic resonance imaging were eligible to participate. Consented patients were randomized intraoperatively to NO REMP or REMP. Study visits were conducted preoperatively and 3, 6, 12, and 24 months postoperatively. The primary outcome was the Western Ontario Shoulder Instability score. Secondary outcomes included incidence of postoperative recurrent shoulder instability, Simple Shoulder Test, American Shoulder and Elbow Surgeons score, range of motion, complications, and revision surgery. To compare groups, a mixed-effects linear model was used for continuous variables and a χ2 or Fisher's exact test for categorical data. A Kaplan-Meier survival analysis assessed survival distribution between groups. RESULTS: One hundred and eight patients were randomized to Bankart repair with (n = 54) or without (n = 54) remplissage. The mean follow-up was 26.5 months (21-53 months) and 24.3 months (23-64 months) for the REMP and NO REMP groups, respectively. Rates of postoperative recurrent instability were higher (P = .027) in the NO REMP group with 9 of 50 (18%) vs. 2 of 52 (4%) postoperative dislocations in the REMP group. There were no significant differences in patient-reported outcomes between groups at any time point. Survival curve distributions were also significantly different favoring REMP (χ2 = 5.255, P = .022). There was a significant difference in rate of revision surgery between groups with 6 in the NO REMP and none in the REMP groups (P = .029). Post hoc, patients were noted to have a higher risk for re-dislocation if their Hill-Sachs lesion was ≥20 mm in width or ≥15% of humeral head diameter. One intraoperative complication was reported in the REMP group. CONCLUSIONS: There is significantly greater risk of postoperative recurrent instability in patients who did not have a remplissage performed in conjunction with an arthroscopic Bankart repair for the treatment of traumatic recurrent anterior shoulder instability with Hill-Sachs lesions of any size and minimal glenoid bone loss (<15%) at 2 years postoperatively. Otherwise, there are no differences in patient-reported outcomes, complications, or shoulder function at 2 years postoperatively. In addition, the remplissage procedure has significantly lower rates of re-dislocation in high-risk patients with Hill-Sachs lesions ≥20 mm and/or ≥15% in size.

PURPOSE: To compare 90-day postoperative complications between patients undergoing outpatient versus inpatient arthroscopic rotator cuff repairs (RCR) and identify risk factors associated with postoperative complications. METHODS: An administrative claims database was used to identify patients undergoing arthroscopic RCR from 2007 to 2015. Patients were categorized based on length of hospital stay (LOS) with inpatient RCR defined as patients with ≥1 day LOS, and outpatient RCR as patients discharged day of surgery (LOS = 0). Inpatient and outpatient RCR groups were matched based on age, sex, Charlson comorbidity index (CCI), and various medical comorbidities using 1:1 propensity score analysis. Patient factors, concomitant procedures, total adverse events (TAEs), medical adverse events (MAEs), and surgical adverse events (SAEs) were compared between the matched groups. Multiple logistic regression analysis was performed to identify risk factors associated with increased complications. RESULTS: After matching, there were 2812 patients (50% outpatient) included in the study. Within 90 days following arthroscopic RCR, the incidence of TAEs (8.9% vs 3.6%, P < .0001), SAEs (2.7% vs 0.9%, P = .0002), and MAEs (6.4% vs 3.0%, P < .0001) were significantly greater for the inpatient RCR group. The multivariate model identified inpatient RCR (LOS ≥1 day), greater CCI, and anxiety or depression as independent predictors for TAEs after arthroscopic RCR. Open biceps tenodesis and inpatient RCR were independent predictors of SAEs, whereas greater CCI, anxiety or depression, and inpatient RCR were independent predictors for MAEs within 90 days after arthroscopic RCR. CONCLUSIONS: Inpatient arthroscopic RCR is associated with increased risk of 90-day postoperative complications compared with outpatient. However, there is no difference for all-cause or pain-related emergency department visits within 90 days after surgery. In addition, the multivariate model identified inpatient RCR, greater CCI, and diagnosis of anxiety or depression as independent risk factors for 90-day TAEs after arthroscopic RCR. LEVEL OF EVIDENCE: III, Retrospective cohort study.

BACKGROUND: The biceps tendon is a known source of shoulder pain. Few high-level studies have attempted to determine whether biceps tenotomy or tenodesis is the optimal approach in the treatment of biceps pathology. Most available literature is of lesser scientific quality and shows varying results in the comparison of tenotomy and tenodesis. PURPOSE: To compare patient-reported and objective clinical results between tenotomy and tenodesis for the treatment of lesions of the long head of the biceps brachii. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: Patients aged ≥18 years undergoing arthroscopic surgery with intraoperative confirmation of a lesion of the long head of the biceps tendon were randomized. The primary outcome measure was the American Shoulder and Elbow Surgeons (ASES) score, while secondary outcomes included the Western Ontario Rotator Cuff Index (WORC) score, elbow and shoulder strength, operative time, complications, and the incidence of revision surgery with each procedure. Magnetic resonance imaging was performed at postoperative 1 year to evaluate the integrity of the procedure in the tenodesis group. RESULTS: A total of 114 participants with a mean age of 57.7 years (range, 34 years to 86 years) were randomized to undergo either biceps tenodesis or tenotomy. ASES and WORC scores improved significantly from pre- to postoperative time points, with a mean difference of 32.3% (P < .001) and 37.3% (P < .001), respectively, with no difference between groups in either outcome from presurgery to postoperative 24 months. The relative risk of cosmetic deformity in the tenotomy group relative to the tenodesis group at 24 months was 3.5 (95% CI, 1.26-9.70; P = .016), with 4 (10%) occurrences in the tenodesis group and 15 (33%) in the tenotomy group. Pain improved from 3 to 24 months postoperatively (P < .001) with no difference between groups. Cramping was not different between groups, nor was any improvement in cramping seen over time. There were no differences between groups in elbow flexion strength or supination strength. Follow-up magnetic resonance imaging at postoperative 12 months showed that the tenodesis was intact for all patients. CONCLUSION: Tenotomy and tenodesis as treatment for lesions of the long head of biceps tendon both result in good subjective outcomes but there is a higher rate of Popeye deformity in the tenotomy group.

BACKGROUND: Loss of motion (LOM) remains a common complication after anterior cruciate ligament (ACL) reconstruction and can be detrimental to patient outcomes after surgery. LOM is multifactorial, but nonsurgical and surgical solutions to this complex problem are available. A paucity of quality data exists evaluating clinical outcomes after the surgical treatment of patients with LOM after ACL reconstruction. HYPOTHESIS: Patients undergoing surgical lysis of adhesions and manipulation under anesthesia for LOM after ACL reconstruction will exhibit decreased function, lower outcome scores, and delayed time of release to play when compared with matched controls without LOM. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A database of 1572 patients undergoing ACL reconstruction was sampled from 2013 to 2017 to identify a total of 58 patients (LOM group [n = 29] vs matched control group [n = 29]). Group comparisons were examined for patients requiring a second surgical procedure for LOM versus matched controls after ACL reconstruction for differences in surgical timing, self-reported International Knee Disability Committee scores, objective function at release to play, and subjective knee function at 2 years with the Single Assessment Numeric Evaluation. The risk of a type I error was set at α = .05 for all statistical analyses. RESULTS: Patients who underwent lysis of adhesions and manipulation under anesthesia for LOM after ACL reconstruction exhibited no differences in Single Assessment Numeric Evaluation knee function at 2 years when compared with matched controls (85.8 ± 14.9 vs 88.0 ± 10.8, P = .606). All patients met release-to-play criteria. Only International Knee Disability Committee scores (P = .046) and single-legged hop testing (P = .050) reached statistically significant differences, with higher scores in the control group. There was no difference in the time to release to play (P = .034) or level of participation (P = .180) between the control and surgical groups. Subjective function scores at 2 years were not significantly different between groups. Tourniquet time during the index ACL reconstruction was shorter in the control group (P = .034). CONCLUSION: The findings of this study suggest that patients who undergo surgical treatment for LOM after ACL reconstruction can release to play at similar times but display relative deficits in single-legged-hop symmetry and lower self-reported function when compared with matched controls. Longer surgical times may increase the risk for LOM after ACL reconstruction. REGISTRATION: NCT03704376 (ClinicalTrials.gov identifier).

BACKGROUND: Corticosteroid injections are a common treatment for rotator cuff tears. Because of concerns of infection, a surgical procedure is often delayed following injections. The purpose of this investigation was to determine if there is a temporal relationship between corticosteroid injections and the risk of surgical site infection after arthroscopic rotator cuff repair. We hypothesized that the incidence of surgical site infection is higher in patients who received a preoperative injection and this relationship exists in a temporal manner as those patients receiving an injection closer to the operative date have a higher risk of infection. METHODS: The PearlDiver database was reviewed for patients undergoing arthroscopic rotator cuff repair from 2007 to 2016. Patients were stratified into 2 cohorts: those undergoing arthroscopic rotator cuff repair within 1 year of injection (n = 12,060), and those undergoing arthroscopic rotator cuff repair without prior injection (n = 48,763). Patients with preoperative injections were further stratified by the duration in months that the injection was performed prior to the surgical procedure. Surgical site infection within 6 months of the surgical procedure was recorded. Statistical analysis included chi-square and multivariate binomial logistic regression analyses to identify risk factors for surgical site infection. Results were considered significant at p < 0.05. RESULTS: There was no significant difference in the incidence of surgical site infection in patients receiving a shoulder injection at 0.7% compared with the control cohort at 0.8% (odds ratio [OR], 0.9 [95% confidence interval (CI), 0.7 to 1.1]; p = 0.2). However, patients receiving an injection within 1 month prior to operative management had a significantly higher rate of surgical site infection overall at 1.3% compared with the control group at 0.8% (OR, 1.7 [95% CI, 1.0 to 2.9]; p = 0.04). On multivariate analysis, male sex (OR, 1.7 [95% CI, 1.4 to 1.9]; p = 0.001), obesity (OR, 1.4 [95% CI, 1.2 to 1.6]; p < 0.001), diabetes (OR, 1.3 [95% CI, 1.1 to 1.5]; p < 0.001), smoking status (OR, 1.7 [95% CI, 1.4 to 1.9], p < 0.001), and preoperative corticosteroid injections within 1 month of the surgical procedure (OR, 2.1 [95% CI, 1.5 to 2.7]; p < 0.001) were independent risk factors for development of a surgical site infection. CONCLUSIONS: Injections within 1 month of arthroscopic rotator cuff repair significantly increases the risk of surgical site infection. However, there is no increased risk of infection if the surgical procedure is delayed by 1 month following an injection. LEVEL OF EVIDENCE: Therapeutic Level III.

BACKGROUND: Biceps tenodesis may be performed for symptomatic tendinopathy or tearing of the long head of the biceps tendon. Biceps tenodesis is also commonly performed as an adjunctive procedure. However, the indications and prevalence of biceps tenodesis have expanded. PURPOSE: To establish the incidence and risk factors for revision biceps tenodesis. STUDY DESIGN: Case-control study; Level of evidence, 2. METHODS: The PearlDiver database of Humana patient data was queried for patients undergoing arthroscopic or open biceps tenodesis (Current Procedural Terminology [CPT] 29828 and CPT 23430, respectively) from 2008 through the first quarter of 2017. Patients without a CPT laterality modifier were excluded from analysis. Revision biceps tenodesis was defined as patients who underwent subsequent ipsilateral open or arthroscopic biceps tenodesis. The financial impact of revision biceps tenodesis was also calculated. Multivariate binomial logistic regression was performed to identify risk factors for revision biceps tenodesis, such as patient demographics as well as concomitant procedures and diagnoses. Odds ratios (ORs) and 95% CIs were calculated, and all statistical comparisons with P < .05 were considered significant. RESULTS: There were 15,257 patients who underwent biceps tenodesis. Of these, 9274 patients (60.8%) underwent arthroscopic biceps tenodesis, while 5983 (39.2%) underwent open biceps tenodesis. A total of 171 patients (1.8%) and 111 patients (1.9%) required revision biceps tenodesis after arthroscopic and open biceps tenodesis, respectively (P = .5). Male sex (OR, 1.38 [95% CI, 1.04-1.85]; P = .02) was the only independent risk factor for revision biceps tenodesis after the index open biceps tenodesis. After arthroscopic biceps tenodesis, age >45 years (OR, 0.58 [95% CI, 0.39-0.89]; P = .01) and concomitant rotator cuff tear (OR, 0.58 [95% CI, 0.47-0.71]; P < .001) were independent protective factors for revision biceps tenodesis. The total cost of revision biceps tenodesis after open and arthroscopic biceps tenodesis was US$3427.95 and US$2174.33 per patient, respectively. CONCLUSION: There was no significant difference in the revision rate between arthroscopic and open biceps tenodesis. Risk factors for revision surgery included male sex for open biceps tenodesis, while age >45 years and rotator cuff tears were protective factors for arthroscopic biceps tenodesis.
ABSTRACT
PURPOSE: To determine whether an association exists between preoperative shoulder injections and reoperations in patients undergoing arthroscopic rotator cuff repair (aRCR). METHODS: The PearlDiver Patient Records Database was reviewed for Humana-insured patients undergoing aRCR after a shoulder injection. Two matched groups were created: aRCR within 1 year of injection (n = 12,054) and aRCR without prior injection within 1 year of surgery (n = 12,054). Reoperation rates within 3 months, at 3 to 6 months, and at 6 to 12 months postoperatively were assessed. Statistical analysis was performed with the χ-square test. RESULTS: The rate of reoperation within 3 months of the index procedure was higher in the control group (3.7% vs 3.1%, P = .01); however, 3 to 6 months after the index procedure, the rate of reoperation was higher in patients who received an injection within 1 year of the index procedure (1.8% vs 1.4%, P = .03). During the same intervals, the rate of revision rotator cuff repair (RCR) within 3 months of the index procedure was higher in the control group (2.9% vs 2.6%) and the rate of revision RCR 3 to 6 months after the index procedure was higher in patients who received an injection within 1 year of the index procedure (1.1% vs 0.9%); however, these results were not statistically significant (P = .3 and P = .8, respectively). The incidence of revision RCR (1.6% vs 1.1%; odds ratio, 1.4; P = .003) and incidence of subacromial decompression (1.5% vs 1.1%; odds ratio, 1.3; P = .01) 6 to 12 months after the index procedure were significantly higher in patients receiving an injection within 1 year before surgery. CONCLUSIONS: Preoperative shoulder injections may increase the risk of revision RCR and subacromial decompression by up to 150% in patients 6 to 12 months after index surgery compared with patients who did not receive a preoperative injection. However, the absolute increase in these revision procedures is only 0.5%. LEVEL OF EVIDENCE: Level III, comparative study.

PURPOSE: To quantify the torsional load to fracture for subpectoral biceps tenodesis with interference screw fixation. METHODS: We randomized 28 specimens from 14 matched-pair full-length humeri (mean age, 55.3 years) into 3 groups: (1) empty ream group (ERG), (2) screw-only group (SOG), and (3) screw-plus-biceps tendon group (SBG). In each group, 1 humerus of each matched pair was prepared according to group allocation and the contralateral humerus remained intact as a control. In the ERG, an 8-mm unicortical hole was reamed 1 cm proximal to the inferior border of the pectoralis major tendon insertion; in the SOG, the humerus was filled with an 8-mm × 12-mm PEEK (polyether ether ketone) screw; and in the SBG, the humerus was filled with a PEEK screw and the cadaveric long head of the biceps tendon. Humeri were tested under torsional displacement at a rate of 1°/s until fracture. Maximum torque, energy to maximum torque, and linear stiffness were used to assess humerus strength. RESULTS: Compared with contralateral intact specimens, the maximum torque to fracture was reduced by 28% in the ERG (P = .005), 30% in the SOG (P = .014), and 20% in the SBG (P = .046). Energy to maximum torque was similarly reduced in the ERG (P = .007), SOG (P = .023), and SBG (P = .049). Stiffness was increased by 4% in the ERG (P = .498), 9% in the SOG (P = .030), and 4% in the SBG (P = .439). CONCLUSIONS: Drilling an 8-mm unicortical hole in zone 3 of the bicipital tunnel for open subpectoral biceps tenodesis reduces the torsional load to humeral fracture up to 28% at time 0. The addition of a PEEK tenodesis screw alone reduced the maximum torque by 30%, and the addition of a screw with the long head of the biceps tendon reduced the maximum torque by 20%. The total load to fracture was reduced in all settings. Stiffness was not significantly different for the ERG and SBG, but stiffness was significantly higher for the SOG compared with the intact matched humeri at time 0. CLINICAL RELEVANCE: When performing a biceps tenodesis, humeral fracture susceptibility is increased with an applied torsional load at time 0. Thus providers must be aware of this reduced integrity when a subpectoral biceps tenodesis is used.

The purpose of this study was to investigate the ability of worker's compensation (WC) patients to return to work without restrictions after hip arthroscopy. Twenty-nine WC patients along with age and gender matched controls who underwent hip arthroscopy were retrospectively reviewed after achieving maximum medical improvement (MMI) status at minimum 1 year postoperatively. Patient demographic factors were evaluated, along with the Hip Outcome Score Activities of Daily Living and Sports-Specific subscales, and the modified Harris Hip Score (mHHS). The majority of WC patients were able to return to work without restrictions after reaching MMI (20/29, 69.0%). WC patients who failed to return to work without restrictions had a prolonged time from injury to surgery (3.01 ± 2.16 months versus 6.36 ± 4.16 months; P = 0.0079), more concomitant orthopedic injuries (4/20, 20.0% versus 9/9, 100%; P = 0.0001), and higher body mass index (BMI) (26.61 ± 3.52 versus 29.54 ± 3.43; P = 0.047) than those who returned to work without restrictions. WC patients had significant improvement of patient-reported outcome scores following hip arthroscopy (P < 0.0001), but WC patients who returned to work without restrictions had higher scores than those who failed to do so (HOD-ADL: P < 0.0001; HOS-SS: P = 0.004; mHHS: P = 0.009). The majority of WC patients are able to return to work without restrictions when they reach MMI status following hip arthroscopy. Factors associated with failure to return to work without restrictions include prolonged time course between injury and surgical treatment, concomitant orthopaedic injuries, and a higher BMI. Level III, retrospective case-control study.
