Declining Inflation-Adjusted Medicare Physician Fees: An Unsustainable Trend in Hip Arthroscopy.

INTRODUCTION: Although hip arthroscopy continues to be one of the most used arthroscopic procedures, no focused, comprehensive evaluation of reimbursement trends has been conducted. The purpose of this study was to analyze the temporal Medicare reimbursement trends for hip arthroscopy procedures. METHODS: From 2011 to 2021, the Medicare Physician Fee Schedule Look-Up Tool was queried for Current Procedural Terminology (CPT) codes related to hip arthroscopy (29860 to 29863, 29914 to 29916). All monetary data were adjusted to 2021 US dollars. The compound annual growth rate and total percentage change were calculated. Mann-Kendall trend tests were used to evaluate the reimbursement trends. RESULTS: Based on the unadjusted values, a significant increase in physician fee was observed from 2011 to 2021 for CPT codes 29861 (removal of loose or foreign bodies; % change: 3.49, P = 0.03) and 29862 (chondroplasty, abrasion arthroplasty, labral resection; % change: 3.19, P = 0.03). The remaining CPT codes experienced no notable changes in reimbursement based on the unadjusted values. After adjusting for inflation, all seven of the hip arthroscopy CPT codes were observed to experience a notable decline in Medicare reimbursement. Hip arthroscopy with acetabuloplasty (CPT: 29915) and labral repair (CPT: 29916) exhibited the greatest reduction in reimbursement with a decrease in physician fee of 24.69% (P < 0.001) and 24.64% (P < 0.001), respectively, over the study period. DISCUSSION: Medicare reimbursement for all seven of the commonly used hip arthroscopy services did not keep up with inflation, demonstrating marked reductions from 2011 to 2021. Specifically, the inflation-adjusted reimbursements decreased between 19.23% and 24.69% between 2011 and 2021.

Common characteristics of shoulder injury related to vaccine administration following COVID-19 vaccination: a comprehensive systematic review.

BACKGROUND: The pathogenesis of shoulder injury related to vaccine administration (SIRVA) is incompletely understood, but it is postulated to be an immune-mediated inflammatory response to a vaccine antigen, leading to shoulder pain and dysfunction. The purpose of this investigation is to systematically review the literature related to SIRVA specifically after the COVID-19 vaccination by describing the diagnostic and clinical characteristics, diagnoses associated with SIRVA, and incidence between vaccine types. METHODS: A systematic review was performed to identify level I to IV studies and case descriptions of shoulder pain occurring after COVID-19 vaccination. To confirm that no studies were missing from the systematic review, references of studies from the initial search were scanned for additional relevant studies. RESULTS: A total of 22 studies, comprised of 81 patients, were identified meeting the inclusion/exclusion criteria. Reports were most commonly published from countries in Asia (53.1%; n = 43/81). The most commonly described vaccines were Oxford-AstraZeneca at 37.0% (n = 30/81) and Pfizer-BioNTech at 33.3% (n = 27/81). Symptoms occurred most commonly after at least 72 hours of administration (30.9%, n = 25/81). One hundred percent of patients (n = 81/81) described pain as an associated symptom and 90.1% of patients (n = 73/81) described multiple symptoms. The diagnostic modalities utilized to identify a specific pathology consisted of magnetic resonance imaging (55.6%; n = 45/81), ultrasound (28.4; n = 23/81), radiograph (25.9%; n = 21/81), and computed tomography (4.9%; 4/81). Nearly a third of patients (32.1%; n = 26/81) were diagnosed with bursitis, while 22 (27.2%) were diagnosed with adhesive capsulitis, 17 (21.0%) with either rotator cuff tear or tendinopathy, and 14 (17.3%) with polymyalgia rheumatica or polymyalgia rheumatica-like syndrome. The 2 most common treatment options were physical therapy (34.6%; n = 28/81) and nonsteroidal anti-inflammatory medications (33.3%; 27/81). The majority of SIRVA cases (52.1%; n = 38/73) completely resolved within a few weeks to months. CONCLUSION: Despite the limited quality and lack of large-scale studies, it is important for providers to recognize SIRVA as a potential risk factor as the number of patients receiving COVID-19 vaccinations and boosters continues to rise.

Patient Preferences and Perceptions of Provider Diversity in Orthopaedic Surgery.

BACKGROUND: Orthopaedic surgery in the U.S. historically has been among the least demographically diverse specialties in medicine. Currently, limited data exist on how patients perceive diversity within the field and what patients look for when choosing an orthopaedic surgeon. The purpose of this study was to identify specific patient preferences for surgeon demographics and understand patient perceptions of racial and gender diversity in orthopaedic surgery. METHODS: Nonconsecutive patients from orthopaedic clinics affiliated with a U.S. academic health system voluntarily completed a 39-item questionnaire that surveyed basic demographic information, perception of diversity, racial and gender preferences during surgeon selection, and perception of health-care inequalities. Bivariate analyses were used to test the association between patient-surgeon demographic variables and ratings of diversity. Multiple regression models were used to identify independent predictors of overall perceived diversity ratings. RESULTS: A total of 349 patients (80.6% White, 17.9% Black, and 1.5% other) were analyzed. Black patients were more likely to experience difficulty relating to their surgeon than White patients (11.48% versus 2.29%; odds ratio [OR], 5.62; 95% confidence interval [CI], 1.55 to 21.1; p = 0.004). Moreover, Black patients were more likely to perceive racial bias from their surgeon than White patients (5.17% versus 0.37%; OR, 14.44; 95% CI, 1.14 to 766.29; p = 0.02). While the level of racial diversity perceived by White patients (2.57 of 10) was significantly higher than that perceived by Black patients (2.10 of 10) (p = 0.001), the absolute difference between these 2 figures was small, suggesting that both groups perceived racial diversity in orthopaedics to be low. White and Black patients differed in their importance ranking of a surgeon's race (p < 0.0001): Black patients ranked a surgeon's race with higher importance (mean, 3.49 of 10) when selecting a surgeon compared with White patients (1.45 of 10). Both male and female patients gave relatively low importance rankings for a surgeon's gender (mean, 1.58 of 10 and 2.15 of 10, respectively, p = 0.02). CONCLUSIONS: Patients in this study did not perceive orthopaedic surgery as a diverse field (overall diversity rating, <3 of 10). There were significant racial and gender differences in patients' preferences for specific physician characteristics when choosing an orthopaedic surgeon, which may help explain some instances of perceived racial bias and difficulty relating to their orthopaedic surgeon.

Increase in Deltoid Compartment Pressures Immediately After Arthroscopic Rotator Cuff Repair Does Not Significantly Affect Postoperative Opioid Consumption.

Purpose: To investigate the association between changes in individual (anterior, lateral, and posterior) and overall deltoid compartment pressures and postoperative opioid consumption up to 14 days after primary double-row arthroscopic rotator cuff repair (ARCR). Methods: In 113 consecutive patients undergoing primary double-row ARCR, anterior, lateral, and posterior deltoid compartment pressures were measured prior to incision and immediately after closure with a manometer. Postoperatively, all patients were provided with an identical rehabilitation protocol, quantity and dose of opioid tablets, and pain journal in which to record daily opioid consumption and visual analog scale pain scores for 14 days after surgery. The pain journals were collected at the first postoperative visit, and opioid consumption was calculated based on morphine equivalents. Statistical analysis was performed to determine the association between deltoid compartment pressures and opioid consumption postoperatively. Results: Sixty-nine percent of patients who met the inclusion criteria (74 of 107) returned the pain journals. The mean age at the time of surgery was 57.4 ± 8.8 years (range, 30-75 years), with female patients being significantly older (P = .03). The mean length of surgery was 71.7 ± 16.3 minutes. No significant association between increase in individual (anterior, lateral, or posterior) or mean overall compartment pressures and morphine equivalents of opioid consumption was appreciated on any postoperative day. Conclusions: No significant correlation between increase in individual or overall deltoid compartment pressures after ARCR and postoperative opioid consumption in the immediate postoperative period was found in this study. Level of Evidence: Level II, prospective cohort study.

Wearable technology in the sports medicine clinic to guide the return-to-play and performance protocols of athletes following a COVID-19 diagnosis.

The coronavirus disease 2019 (COVID-19) pandemic has enabled the adoption of digital health platforms for self-monitoring and diagnosis. Notably, the pandemic has had profound effects on athletes and their ability to train and compete. Sporting organizations worldwide have reported a significant increase in injuries manifesting from changes in training regimens and match schedules resulting from extended quarantines. While current literature focuses on the use of wearable technology to monitor athlete workloads to guide training, there is a lack of literature suggesting how such technology can mediate the return to sport processes of athletes infected with COVID-19. This paper bridges this gap by providing recommendations to guide team physicians and athletic trainers on the utility of wearable technology for improving the well-being of athletes who may be asymptomatic, symptomatic, or tested negative but have had to quarantine due to a close exposure. We start by describing the physiologic changes that occur in athletes infected with COVID-19 with extended deconditioning from a musculoskeletal, psychological, cardiopulmonary, and thermoregulatory standpoint and review the evidence on how these athletes may safely return to play. We highlight opportunities for wearable technology to aid in the return-to-play process by offering a list of key parameters pertinent to the athlete affected by COVID-19. This paper provides the athletic community with a greater understanding of how wearable technology can be implemented in the rehabilitation process of these athletes and spurs opportunities for further innovations in wearables, digital health, and sports medicine to reduce injury burden in athletes of all ages.

Effects of Opioid-Limiting Legislation and Increased Provider Awareness on Postoperative Opioid Use and Complications After Hip Arthroscopy.

Background: On August 31, 2017, Ohio passed legislation that regulates how opioids can be prescribed postoperatively. Studies have shown that such legislation is successful in reducing the morphine milligram equivalents (MMEs) prescribed after certain orthopaedic procedures. Purpose: (1) To determine if the opioid prescription-limiting legislation in Ohio reduced the cumulative MMEs prescribed after hip arthroscopy without significantly affecting the rates of emergency department (ED) visits, hospital readmissions, and reoperations within 90 days postoperatively, and (2) to assess risk factors associated with increased postoperative opioid dosing. Study Design: Cohort study; Level of evidence, 3. Methods: This study included patients who underwent primary and revision hip arthroscopy at a single institution over a 4-year period. The prelegislation (PRE) and postlegislation (POST) groups were defined as patients who underwent surgery before August 31, 2017, and on/after this date, respectively. The Ohio Automated Rx Reporting System was queried for controlled-substance prescriptions from 30 days preoperatively to 90 days postoperatively, and patient medical records were reviewed to collect demographic, medical, surgical, and readmission data. Inverse probability weighting-adjusted mean treatment effect regression models were used to measure the difference in mean outcomes between the PRE and POST cohorts. Results: A total of 546 patients (228 PRE, 318 POST) were identified. There was a 25% reduction in the cumulative MMEs prescribed to the POST group as compared with the PRE group during the first 90 days postoperatively (840 vs 1125 MME, respectively; P < .01). The legislation was associated with a significant decrease in the cumulative MMEs prescribed in the first 90 postoperative days (mean treatment effect = -280.6; P < .01), and there were no significant between-group differences in the frequency of ED encounters (8.8% PRE, 11.6% POST; P = .32), hospital readmissions (1.3% PRE, 0.9% POST; P = .70), or reoperations (0.9% PRE, 0.6% POST; P ≥ .99) during this period. Preoperative opioid use was a significant independent risk factor for increased cumulative MMEs in the first 90 days postoperatively (ß = 275; P < .01). Conclusion: Opioid prescription-limiting legislation in Ohio was associated with significant reductions in opioid MMEs dosing in the 90-day period following hip arthroscopy. This legislation had no significant effect on ED utilization, hospital readmissions, or reoperations within the same period. Preoperative opioid use was a significant risk factor for increased MME dosing after hip arthroscopy.

Femoral Version May Impact Hip Arthroscopy Outcomes in Select Patient Populations: A Systematic Review.

PURPOSE: To provide further clarity regarding the management of patients with abnormal femoral version in the setting of hip arthroscopy and will discuss the definition of femoral version, the diagnostic and clinical evaluation of abnormal femoral version, and several described measurement techniques. METHODS: A systematic review was conducted in literature published before August 2021 that measured femoral version and reported patient-reported outcomes measures or rates of subsequent procedures following hip arthroscopy. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed and the electronic databases, PubMed, OvidMedLine, Scopus, and Web of Science were searched. Two blinded reviews screened and evaluated data quality using the Newcastle-Ottawa Scale. RESULTS: Eighteen studies were included with 11 studies reporting patient outcomes and 7 studies reporting rates of subsequent procedures. The most commonly used definition of femoral version was 5° to 20° of femoral anteversion. Computed tomography scan was the most commonly used imaging modality. The majority of studies (7 of 11) demonstrated that femoral version does not have an impact on patient-reported outcomes measures and is not predictive of clinically meaningful improvement scores. However, in select studies, patients with femoral retroversion were found to experience slightly inferior outcomes following hip arthroscopy for femoroacetabular impingement. While femoral retroversion may be a risk factor for subsequent procedures, 3 of 7 studies refute this claim. Although in patients with borderline hip dysplasia, excessive femoral anteversion led to greater rates of subsequent hip procedures. CONCLUSIONS: While the majority of studies show that femoral version does not have an impact on patient-reported outcomes following hip arthroscopy, those with femoral retroversion and with excessive anteversion with coexisting borderline hip dysplasia need to be educated on their increased risk of subsequent operation. Ultimately, this review suggests that clinical improvement can likely be achieved regardless of femoral version. LEVEL OF EVIDENCE: IV; systematic review of Level I-IV studies.

The safe zones for endoscopic proximal hamstring repair: a cadaveric assessment of standard portal placement and their relationship to major neurovascular structures.

PURPOSE: To define the anatomical relationship of the major neurovascular structures to the standard endoscopic portals used in endoscopic hamstring repair. A secondary outcome was to determine the safest angle of insertion from each standard portal. METHODS: Endoscopic portals were established in the 3 standard locations (lateral, medial, and inferior) and Steinmann pins inserted at various angles. Each hip was dissected and the distance between the pins and the pertinent anatomy measured. RESULTS: The lateral portal placed the sciatic and posterior femoral cutaneous (PFC) nerves at greatest risk: direct injury to the sciatic nerve was seen in 11/30 (37%) of the lateral portals sited. A lateral portal with an approach at 60° was the most dangerous orientation with a mean distance of 0.36 ± 0.49 mm and 4.30 ± 2.69 mm from the sciatic and PFC nerves, respectively (p < 0.001). The 60° medial portal was the safest of all portals measured, at a mean distance of 67.37 ± 11.06mm (range, 47-78 mm) from the sciatic nerve and 58.90 ± 10.57 mm (range 40-70 mm) from the PFC nerve. CONCLUSIONS: While currently described techniques recommend establishing the standard lateral portal first, this study shows that it carries the highest risk of injury if used blind. We recommend that the standard medial endoscopic portal is established first to identify the neurovascular structures and minimise iatrogenic neurovascular injury. The inferior and lateral portals can then be established created under direct vision. The lateral portal should be inserted in a more horizontal orientation to decrease the risk of nerve injury.

Oral Ketorolac as an Adjuvant Agent for Postoperative Pain Control After Arthroscopic Anterior Cruciate Ligament Reconstruction: A Prospective, Randomized Controlled Study.

INTRODUCTION: Successful outpatient anterior cruciate ligament (ACL) reconstruction hinges on effective analgesia. Routinely, oral narcotic agents have been the preferred analgesic postoperatively in orthopaedic surgery. However, these agents have several known adverse effects and are associated with a potential for abuse. This study evaluates the efficacy of ketorolac, a nonsteroidal anti-inflammatory drug with analgesic properties, as an adjuvant agent for postoperative pain control after ACL reconstruction. METHODS: Adult patients undergoing primary ACL reconstruction were prospectively enrolled. Exclusion criteria involved patients with a history of bleeding diathesis, renal dysfunction, chronic analgesia use, or alcohol abuse. Eligible patients were randomized into one of two groups. The control group received a standard-of-care pain protocol involving oxycodone-acetaminophen 5 to 325 on discharge. The ketorolac group additionally received intravenous ketorolac postoperatively and 3 days of oral ketorolac on discharge. Pain levels and total narcotic utilization were recorded three times per day for the first 5 days after surgery. Pain and functional outcomes were obtained at 2 and 6 weeks postoperatively. RESULTS: The final analysis included 48 patients; the mean age of the cohort was 32 ± 11.6 years, and 60.4% of patients were female. No differences were observed in preoperative demographics, comorbidities, and preoperative functional scores between the two groups. Over the first 5 days after surgery, patients in the ketorolac group consumed a mean of 45.4% fewer narcotic pills than the control group (P < 0.001). In addition, mean postoperative pain scores were 22.36 points lower for patients in the ketorolac group (P < 0.001). There was no difference in functional outcome scores at up to 6 weeks postoperatively or adverse events between the two groups with no reported cases of gastrointestinal bleeding. DISCUSSION: The use of adjunctive intravenous and short-term oral ketorolac substantially reduces narcotic utilization and pain levels after ACL reconstruction.

Use of Anatomic Radiographic Horizons for the Lateral Center-Edge Angle in the Classification of Hip Dysplasia.

BACKGROUND: The lateral center-edge angle of Wiberg (LCEA) and Tönnis angle (TA) rely on a "horizon" that functions as a reference point for measurements of hip dysplasia on weightbearing anteroposterior pelvis radiographs. There are 3 different horizons that are currently utilized depending on surgeon preference: (1) a line parallel to the radiographic floor (F), (2) a line that connects the inferior portions of the acetabular teardrops (ATs), or (3) a line that connects the ischial tuberosities (ITs). It is imperative to accurately assess the degree of hip dysplasia on initial workup to select the appropriate surgical intervention. PURPOSE: To assess how the choice of a radiographic horizon affects the measurements of the LCEA and TA. The secondary purpose was to assess how the horizon affected the classification of hips as either normal, borderline dysplastic, or dysplastic. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 3. METHODS: The LCEA and TA were measured on all preoperative weightbearing anteroposterior pelvis radiographs for 186 consecutive patients who underwent hip preservation surgery between February 2016 and November 2020 (140 hip arthroscopic procedures, 46 combined hip arthroscopic procedures with periacetabular osteotomy), 3 times per hip, each time using an F, AT, and IT horizon. The Student t test was used to analyze the differences in the measurements of the LCEA and TA, and discordance rates in the dysplasia classification between horizons were quantified. RESULTS: For the entire study population, the mean LCEAF (23.4°± 7.4°) was significantly greater than the mean LCEAIT (23.1°± 7.2°) (95% CI, -0.634 to -0.003; P = .047) and mean LCEAAT (23.0°± 7.1°) (95% CI, -0.723 to -0.139; P = .004). There was no difference between the LCEAIT and LCEAAT (95% CI, -0.305 to 0.080; P = .251). When stratified by hip arthroscopic surgery, the mean LCEAF (26.3°± 5.6°) was significantly greater than the mean LCEAAT (25.8°± 5.3°) (95% CI, -0.845 to -0.162; P = .004). Overall, there was a 17.7% and 18.3% discordance rate in the dysplasia classification using the LCEAIT and LCEAAT compared with the LCEAF, respectively. There were no statistically significant differences between the mean TAIT, TAAT, and TAF for the entire study population, the arthroscopic surgery group, and the combined arthroscopic surgery and periacetabular osteotomy group. CONCLUSION: There was no statistical difference between the AT and IT horizons for LCEA measurements. The dysplasia classification was in better agreement between the 2 anatomic horizons compared with the F horizon. The TA was not affected by changes in the horizon.

Surgical Technique of the "Up-The-Neck" View During Hip Arthroscopy for Femoroacetabular Impingement.

In the setting of femoroacetabular impingement, arthroscopy versus open surgery confers many advantages. However, inadequate bony resection remains a concern and is the leading cause of revision surgery. Several strategies have been described to ensure a more-complete resection during hip arthroscopy. In this current technique article, the authors describe a modified anterior portal site view called the "up-the-neck" view. This view allows for greater visualization of the femoral head-neck junction and alleviates challenges faced when assessing resection intraoperatively. The "up-the-neck" view is achieved by placing a 70° arthroscope in the anterior lateral portal and subsequently rotating the camera 90°. The head-neck junction will appear horizontally, rather than vertically, on this view, which allows for the easy identification of missed imperfections. This may reduce the need for revision surgery and future investigation is necessary to determine the reoperation rates following this technique.

Evaluating the Chase Utley Rule: The Association Between a Rule Change and Collision-Related Injuries in Major League Baseball.

Background: Major League Baseball (MLB) adopted a rule change in 2016 to reduce the number of collisions that occur when a player slides into a base. The effect of rule 6.01(j) has not been quantified, and it remains unknown if this rule change has led to improved player safety. Hypothesis: Rule 6.01(j) would be associated with a reduction in the number of collision-related injuries at second base. Study Design: Cohort study; Level of evidence, 3. Methods: Using data from the MLB Health and Injury Tracking System, we quantified the number of collision-related injuries for defensive (ie, fielding) players in the infield at the major and minor league levels between the 2010 and 2019 seasons. We compared the median number of collision-related injuries for defensive players in the infield from before (2010-2015) to after (2016-2019) the implementation of rule 6.01(j) and also calculated the difference in location of the median from the seasons before versus after the rule change. An additional 3 analyses were performed to support or contradict a conclusion that any observed reduction in injuries at the start of the 2016 season was likely caused by the adoption of rule 6.01(j). Results: The median number of collision-related injuries for defensive players at second base decreased from 58.5 to 37.5 injuries per season after the rule change, which was a 36% decrease (difference in location, 19.5 [95% CI, 5.0 to 31.0]; P = .019). In contrast, the median number of collision-related injuries at first base decreased by only 14.1%, from 49.5 before to 42.5 after the rule change (difference in location, -9.0 [95% CI, -4.0 to 18.0]; P = .16), and the median number of collision-related injuries per season at third base was unchanged at 15 per season. Conclusion: This rule change was associated with a decrease in the number of collision-related injuries, with the largest effect observed at second base, as expected.

Emergency Department Utilization Is Low After Outpatient Elective Rotator Cuff Repair.

INTRODUCTION: The purpose of this study was to establish emergency department (ED) utilization rate and reasons for presentation to the ED after outpatient rotator cuff repair (RCR) and determine preoperative predictors for these ED visits. METHODS: Patients who underwent outpatient RCR between 2014 and 2015 were retrospectively evaluated using the New York and Florida State Databases. The primary outcome was all-cause 7- and 30-day ED utilization rates. Reasons for presentation to the ED were recorded and stratified. Univariate and multivariate analyses were done to identify independent predictors of ED utilization. RESULTS: The 7- and 30-day ED visit rates were 3.2% and 5.0%, respectively. The most common cause for an ED visit after outpatient RCR at 7- and 30-days postoperatively were postoperative pain (29.0%) and GI complaints (16.3%), respectively. African American race (odds ratio [OD], 1.69; P < 0.001), Hispanic race (OD, 1.47; P = 0.005), and comorbid diagnoses of hypertension (OD, 1.51; P < 0.001), diabetes (OD, 1.58; P < 0.001), and/or schizophrenia (OD, 5.14; P < 0.001) were independent risk factors for an ED visit at up to 30 days postoperatively. Those with Medicare (OD, 2.01; P < 0.001) or Medicaid (OD, 2.61; P < 0.001) were more than twice as likely to present to the ED within 30 days than those with private health insurance. DISCUSSION: ED utilization after outpatient RCR is uncommon with postoperative pain as the most common chief concern for ED visits within the first 7 days and GI issues as the most common reason for ED encounters at up to 30 days postoperatively. Hypertension, diabetes, renal failure, liver disease, rheumatologic diseases, schizophrenia, depression, and Medicare and Medicaid insurance were independent predictors of ED encounters at up to 30 days postoperatively. Procedures done at freestanding surgery centers were protective against ED utilization. LEVEL OF EVIDENCE: Level III, Retrospective Cohort.

The Role of Imaging in Femoroacetabular Impingement: History, Current Practices, and Future Applications.

¼: Femoroacetabular impingement (FAI) is one of the most common causes of early hip articular cartilage wear and labral damage, and subsequently leads to the onset of hip osteoarthritis. ¼: Cam-type FAI impingement lesions can be best identified with a 90° Dunn lateral radiograph and a cross-table lateral radiograph with 15° of internal rotation; the alpha angle and the femoral head-neck offset are the most used predictive radiographic markers. ¼: FAI lesions with pincer impingement are associated with acetabular retroversion and are more difficult to identify on traditional radiographic imaging; however, the presence of a crossover sign, an ischial spine sign, and/or a posterior wall sign can be useful radiographic markers. ¼: Advanced imaging modalities such as magnetic resonance imaging (MRI) and/or magnetic resonance arthrography (MRA) can also be beneficial in the evaluation of FAI and labral pathology; MRA is more sensitive than MRI in detecting intra-articular pathology. ¼: Computer-assisted navigation for preoperative planning and intraoperative surgical assistance are promising technologies; however, additional studies are needed before they can be utilized safely and effectively.

Oral Ketorolac as an Adjuvant Agent for Postoperative Pain Control After Arthroscopic Rotator Cuff Repair: A Prospective, Randomized, Controlled Study.

BACKGROUND: Arthroscopic rotator cuff repair (RCR) is associated with substantial postoperative pain. Oral narcotic agents are the preferred analgesic postoperatively. However, these agents are associated with several side effects and a potential for abuse. This study evaluates the efficacy of ketorolac as an adjunctive agent for postoperative pain control after arthroscopic RCR. METHODS: Adult patients undergoing arthroscopic RCR were prospectively enrolled and randomized to one of two groups. The control received our institution's standard-of-care pain protocol, including oxycodone-acetaminophen 5 to 325 mg on discharge. The ketorolac group received the standard-of-care protocol, intravenous ketorolac at the completion of the procedure, and oral ketorolac on discharge. Pain and functional outcome scores and narcotic utilization were recorded three times per day for the first 5 days after surgery. Repeat magnetic resonance imaging was done at least 6 months postoperatively. RESULTS: In our study, 39 patients were included for final analysis; the mean age of the cohort was 55.7 ± 10.6 years, and 66.7% of patients were male. No differences were observed in preoperative demographics, comorbidities, cuff tear morphology, and functional scores between the two groups. Over the first 5 days after surgery, patients in the ketorolac group consumed a mean of 10.6 fewer narcotic pills, a consumption reduction of 54.6% (19.42 versus 8.82, P < 0.001). No difference was observed in functional outcome scores at up to 6 weeks postoperatively between the two groups. No difference was observed in adverse events between the two groups with no reported cases of gastritis or gastrointestinal bleeding. Twenty-two of 39 patients underwent repeat magnetic resonance imaging at a mean of 7.9 months postoperatively, of which 5 (22%) demonstrated a retear of their rotator cuff. No significant difference was observed between the ketorolac and control groups in the rate of retear (P = 1.00). DISCUSSION: Adjunctive ketorolac substantially reduces narcotic utilization after arthroscopic RCR.

Endoscopic Treatment of Calcific Tendinitis of the Gluteus Maximus: A Case Report.

CASE: Calcific tendinitis of the gluteus maximus is a rare condition with poorly described operative treatment options. We present a 51-year-old man with chronic left posterolateral hip pain because of gluteus maximus calcific tendinitis that was refractory to conservative treatment. Endoscopy was pursued given the severity and chronicity of his symptoms. The patient remains asymptomatic without recurrence. CONCLUSION: This is the first description of endoscopic management of calcific tendinitis of the gluteus maximus. This is a minimally invasive, efficacious option for management of this pathology.

Clinical and Radiographic Outcomes After Treatment of Patellar Chondral Defects: A Systematic Review.

CONTEXT: There is currently no evidence-based consensus on how to treat a full-thickness, symptomatic articular cartilage injury of the patella, although numerous treatment options are available. OBJECTIVE: To systematically evaluate the functional outcomes after operative treatment of patellar cartilage lesions. Our secondary purpose was to evaluate radiographic outcomes after treatment. DATA SOURCES: PubMed, Cochrane, and Embase. STUDY SELECTION: Studies published between January 1, 1990 and December 31, 2018 that included patient-reported functional outcomes for patients after operative treatment of patellar chondral defects at a minimum 2-year follow-up were included. STUDY DESIGN: Systematic review. LEVEL OF EVIDENCE: Level 4. DATA EXTRACTION: MINORS (Methodological Index for Non-Randomized Studies) score, level of evidence, sample size, demographic data, follow-up data, intervention, functional outcome scores, and magnetic resonance imaging (MRI) data were collected. RESULTS: The review identified 10 studies and 293 patients receiving cartilage restoration procedures for patellar chondral defects with extractable clinical and radiographic results and data on complications and reoperations. All treatments (autologous chondrocyte implantation [ACI], matrix-induced ACI [MACI], autologous osteochondral transplantation [AOT]) utilized in the management of patellar chondral lesions, with the exception of isolated particulated juvenile articular cartilage, demonstrated statistically significant improvements in functional outcome scores compared with preoperative measurements at a minimum of 2-year follow-up. Postoperative MRIs were obtained in 6 studies and found that regardless of treatment, moderate-to-complete infill of patellar cartilage lesions was seen in the majority of patients. While failure rates were low for the various treatment modalities, rates of reoperation were substantial, with up to 40% to 60% reoperation rate seen after ACI. CONCLUSION: Patients treated with ACI, MACI, and AOT all demonstrated statistically significant improvements in functional outcome scores with radiographic evidence of healing at minimum of 2-year follow-up. Evidence is insufficient to recommend one particular treatment over another.

Evaluating the role of graft integrity on outcomes: clinical and imaging results following superior capsular reconstruction.

BACKGROUND: Superior capsular reconstruction (SCR) addresses massive, irreparable rotator cuff tears in young patients. The purpose of this study was to retrospectively evaluate clinical outcomes and graft integrity in patients following SCR. METHODS: Thirty-four consecutive patients undergoing SCR by 2 surgeons with minimum 2-year follow-up were identified. Functional outcomes were obtained, including Simple Shoulder Test (SST), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), visual analog scale (VAS), and Single Assessment Numeric Evaluation (SANE) scores. Graft integrity was evaluated on magnetic resonance images (MRIs). RESULTS: Thirty-five shoulders in 34 patients were identified. Four patients underwent subsequent surgery. The mean preoperative scores were SST 21.6 ± 17.6, ASES 28.3 ± 10.1, SANE 50.6 ± 22.1, and VAS 6.6 ± 1.7. The mean postoperative outcomes were SST 79.1 ± 19.6, ASES 79.9 ± 17.4, SANE 74.3 ± 18.7, and VAS 1.5 ± 2.2. There was statistically significant improvement in SST, ASES, and VAS following SCR. MRI revealed graft failure in 62% (n = 13 of 21) of shoulders. Radiographic evidence of graft healing did not have any effect on SST, ASES, SANE, or VAS scores. CONCLUSION: Given the high rate of graft failure without a significant difference in clinical outcomes, graft healing after SCR might not be an independent predictor of success. The improved clinical improvement in patients undergoing SCR may be due to other known beneficial aspects of the procedure, including partial rotator cuff repair, débridement, and biceps management.

Assessing precision and accuracy of false-profile hip radiographs.

PURPOSE: The purpose of this study was to assess the accuracy and precision of pelvic rotation in existing false-profile (FP) radiographs and to devise a method to improve accuracy and precision of FP radiographs. METHODS: An imaging protocol was developed to obtain FP radiographs. Pelvic rotation was calculated using the described method for FP images obtained in the 3 months prior to and after implementation of this protocol. Student's t-test and variance ratio tests were used to determine differences in mean and variance of pelvic rotation between the 2 cohorts. Pelvic rotation calculation methodology was validated by using fluoroscopic C-arm to obtain AP and rotated images of 10 osteologic pelvises. The ratio of the distance between hip centres of each rotated image and AP image (WP/W) was determined. Intraclass coefficient correlation (ICC) was used to verify the relationship between WP/W and pelvic rotation. RESULTS: Mean WP/W was 0.47 (95% CI, 0.45-0.49). There were significant differences in mean pelvic rotation of the pre-protocol group (47.6°; 95% CI, 45.6-49.5°) and the post-protocol group (60.0°; 95% CI, 58.7-61.3°, p < 0.0001). Additionally, there was a significantly wider distribution of measurements in the pre-protocol group (SD = 7.9°) compared to the post-protocol group (SD = 5.7°, p = 0.0035). CONCLUSIONS: The quality of FP radiographs obtained in the clinical setting may be inconsistent. Standardising FP imaging produces more accurate images. Appropriate FP radiographs should have a distance between hip centres that is approximately 0.5 times the same distance found on an anteroposterior (AP) radiograph.

Is There a Role for Ultrasound in Hip Arthroscopy? A Systematic Review.

PURPOSE: The purpose of this study is to identify and summarize the current utility of intraoperative ultrasound (US) during hip arthroscopy. METHODS: A systematic database query of the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, EMBASE, PubMed (1980 to 2019), and Ovid MEDLINE (1980 to 2019) was performed. After article identification, descriptions of the surgical procedure, use of intraoperative US, procedural complications, and conclusions from each article were recorded and summarized. RESULTS: Five studies met inclusion criteria, all of which were surgical techniques or technical notes. Four of the 5 studies described US used for placement of arthroscopic portals, and 1 described the use of an intraarticular US catheter for the assessment of an osteochondritis dissecans (OCD) lesion. Of the 4 studies using US for portal placement, 3 were performed supine and 1 was performed in the lateral decubitus position. All studies recognized the need for additional US training or the required assistance of a radiologist to incorporate US into a surgical practice. CONCLUSION: Descriptions of intraoperative US during hip arthroscopy are limited in the literature. However, existing technique reports demonstrate the feasibility of US for both portal placement with superficial probes and limited evaluation of cartilage using intraarticular US catheters. LEVEL OF EVIDENCE: V, systematic review.
