Clinical characteristics and long-term outcomes of septic arthritis of the native hip joint: a 20-year retrospective review.

BACKGROUND: The primary purpose of this retrospective case series was to describe the prevalence and outcomes of single-stage hip arthroplasty in patients who were previously treated for septic arthritis of the native hip at our institution over a 20-year period. This study also examined rates of persistent or recurrent infection, reoperation, and mortality for septic arthritis of the native hip. METHODS: Adult patients treated for septic arthritis of the native hip at our institution from 1995 to 2015 were retrospectively identified. Exclusion criteria included age <18 years, missing or incomplete medical records, treatment at an outside institution, and prior surgery of the hip. RESULTS: 97 patients were included in this study. 3 patients (3.1%) who were previously treated for septic arthritis of the native hip underwent single-stage hip arthroplasty an average of 40 ± 25 months from the date of infection. 3 of the 18 (16.7%) patients who were treated with resection arthroplasty underwent second-stage joint reconstruction. There were no cases of periprosthetic joint infection (PJI). 1 patient who underwent single-stage arthroplasty experienced implant-induced metallosis, necessitating removal of the implant. There were no other cases of revision arthroplasty. CONCLUSIONS: The prevalence of single-stage hip arthroplasty in patients with a history of septic arthritis of the native hip joint was 3.1%, which is higher than the prevalence of hip arthroplasty in the United States general population, suggesting that a history of septic arthritis may increase the risk of requiring hip arthroplasty. In the small number of patients who went on to receive a hip replacement, there were no reported cases of PJI. This study suggests that hip arthroplasty is a viable option for patients with symptomatic osteoarthritis and a history of septic arthritis of their hip.

Utility of Artificial Intelligence in Orthopedic Surgery Literature Review: A Comparative Pilot Study.

OBJECTIVE: Literature reviews are essential to the scientific process and allow clinician researchers to advance general knowledge. The purpose of this study was to evaluate if the artificial intelligence (AI) programs ChatGPT and Perplexity.AI can perform an orthopedic surgery literature review. MATERIALS AND METHODS: Five different search topics of varying specificity within orthopedic surgery were chosen for each search arm to investigate. A consolidated list of unique articles for each search topic was recorded for the experimental AI search arms and compared with the results of the control arm of two independent reviewers. Articles in the experimental arms were examined by the two independent reviewers for relevancy and validity. RESULTS: ChatGPT was able to identify a total of 61 unique articles. Four articles were not relevant to the search topic and 51 articles were deemed to be fraudulent, resulting in 6 valid articles. Perplexity.AI was able to identify a total of 43 unique articles. Nineteen were not relevant to the search topic but all articles were able to be verified, resulting in 24 valid articles. The control arm was able to identify 132 articles. Success rates for ChatGPT and Perplexity. AI were 4.6% (6 of 132) and 18.2% (24 of 132), respectively. CONCLUSION: The current iteration of ChatGPT cannot perform a reliable literature review, and Perplexity.AI is only able to perform a limited review of the medical literature. Any utilization of these open AI programs should be done with caution and human quality assurance to promote responsible use and avoid the risk of using fabricated search results.

The effect of subscapularis-specific rehabilitation following total shoulder arthroplasty: a prospective, double-blinded, randomized controlled trial.

BACKGROUND: Patients undergoing a total shoulder arthroplasty (TSA) through a deltopectoral approach will require repair of the subscapularis tendon. There are no universal postoperative guidelines for rehabilitation of the subscapularis specifically. We hypothesize that the addition of a subscapularis-specific regimen will result in improved subscapularis strength and function. METHODS: Adult patients undergoing anatomic TSA for the treatment of primary glenohumeral osteoarthritis were included. Patients were randomized into either the traditional rehabilitation (TR) control group or the subscapularis rehabilitation (SR) group, which consisted of the traditional therapy along with early and additional subscapularis exercises. Baseline demographics, patient-reported outcome measures (PROMs), range of motion (ROM), provocative tests, and subscapularis strength using a handheld dynamometer were measured preoperatively at the initial clinic visit (ICV) as well as 3 months, 6 months, and 1 year postoperatively. The primary outcome of interest was a comparison of subscapularis strength between cohorts relative to preoperative baseline, whereas secondary outcomes were functional, ROM, and PROMs. RESULTS: Sixty-six patients were included in the final analysis (32 TR vs. 34 SR). There were no statistically significant differences between cohorts at the ICV with regard to demographics, baseline subscapularis strength, functional testing, or PROMs. All postoperative time points demonstrated similar subscapularis strength testing between TR and SR groups (P > .05). Additionally, peak and average subscapularis strength testing at 3, 6, and 12 months postoperatively were similar to baseline ICV testing in both groups. Both groups demonstrated improvements across several provocative tests, ROM, and PROM outcome metrics at every postoperative time point as compared to baseline ICV values (P < .05). CONCLUSIONS: Patients undergoing anatomic TSA return to baseline internal rotation strength by 3 months postoperatively and demonstrate significant improvements in function, ROM, and several patient-reported outcome measures. The addition of early and focused subscapularis strengthening exercises does not appear to significantly impact any outcomes when compared to traditional rehabilitation programs.

AOA Critical Issues: Patient-Reported Outcome Measures: Why Every Orthopaedic Practice Should Be Collecting Them.

ABSTRACT: Patient-centered care is essential to providing high-quality value-based care. Patient-reported outcome measures (PROMs) are arguably the best tools available to orthopaedic providers for providing patient-centered care. Many clinical opportunities exist for the implementation of PROMs into routine practice, such as shared decision-making, mental health screening, and prediction of postoperative disposition. Routine use of PROMs is also an adjunct to the streamlining of documentation, patient intake, and telemedicine visits, and hospitals can aggregate PROMs for the purpose of risk stratification. Physicians can harness the power of PROMs for quality improvement initiatives and improvement of the patient experience. Despite these numerous applications, PROMs are frequently underutilized tools. Understanding the many benefits of PROMs may allow orthopaedic practices to justify investing in these valuable tools.

A Cost-Effectiveness Analysis of the Various Treatment Options for Distal Radius Fractures.

Purpose: To conduct a cost-effectiveness study of nonsurgical and surgical treatment options for distal radius fractures using distinct posttreatment outcome patterns. Methods: We created a decision tree to model the following treatment modalities for distal radius fractures: nonsurgical management, external fixation, percutaneous pinning, and plate fixation. Each node of the model was associated with specific costs in dollars, a utility adjustment (quality-adjusted life year [QALY]), and a percent likelihood. The nodes of the decision tree included uneventful healing, eventful healing and no further intervention, carpal tunnel syndrome, trigger finger, and tendon rupture as well as associated treatments for each event. The percent probabilities of each transition state, QALY values, and costs of intervention were gleaned from a systematic review. Rollback and incremental cost-effectiveness ratio analyses were conducted to identify optimal treatment strategies. Threshold values of $50,000/QALY and $100,000/QALY were used to distinguish the modalities in the incremental cost-effectiveness ratio analysis. Results: Both the rollback analysis and the incremental cost-effectiveness ratio analysis revealed nonsurgical management as the predominant strategy when compared with the other operative modalities. Nonsurgical management dominated external fixation and plate fixation, although it was comparable with percutaneous fixation, yielding a $2,242 lesser cost and 0.017 lesser effectiveness. Conclusions: The cost effectiveness of nonsurgical management is driven by its decreased cost to the health care system. Plate and external fixation have been shown to be both more expensive and less effective than other proposed treatments. Percutaneous pinning has demonstrated more favorable effectiveness in the literature than plate and external fixation and, thus, may be more cost effective in certain circumstances. Future studies may find value in investigating further clinical aspects of distal radius fractures and their association with nonsurgical management versus that with plate fixation.

Perceived effectiveness of video interviews for orthopaedic surgery residency during COVID-19.

BACKGROUND: During the 2020-21 residency interview season, interviews were conducted through virtual platforms due to the COVID-19 pandemic. The purpose of this study is to assess the general perceptions of applicants, residents and attendings at a single, large, metropolitan orthopaedic residency with regards to the video interview process before and after the interview season. METHODS: Surveys were sent to all orthopaedic applicants, residents, and attendings before the interview season. Applicants who received interviews and responded to the first survey (46) and faculty who responded to the first survey (28) were sent a second survey after interviews to assess how their perceptions of video interviews changed. RESULTS: Initially, 50% of applicants (360/722) and 50% of faculty and residents (28/56) responded before interview season. After interviews, 55% of interviewees (25/46) and 64% of faculty and residents (18/28) responded. Before interviews, 91% of applicants stated they would prefer in-person interviews and 71% were worried that video interviews would prevent them from finding the best program fit. Before interviews, 100% of faculty and residents stated they would rather conduct in-person interviews and 86% felt that residencies would be less likely to find applicants who best fit the program. Comparing responses before and after interviews, 16% fewer applicants (p = 0.01) perceived that in-person interviews provide a better sense of a residency program and faculty and residents' perceived ability to build rapport with interviewees improved in 11% of respondents (p = 0.01). However, in-person interviews were still heavily favored by interviewees (84%) and faculty and residents (88%) after the interview season. CONCLUSIONS: In-person interviews for Orthopaedic Surgery Residency are perceived as superior and are preferred among the overwhelming majority of applicants, residents, and interviewers. Nevertheless, perceptions toward video interviews improved in certain domains after interview season, identifying potential areas of improvement and alternative interview options for future applicants.

Ultrasound evaluations and guided procedures of the painful joint arthroplasty.

The purpose of this article is to describe the use of ultrasound for the diagnosis and treatment of painful joint arthroplasty. Ultrasound plays a crucial role in the diagnosis of the painful joint arthroplasty, especially given its unique dynamic capabilities, convenience, and high resolution. Ultrasound guidance is also instrumental for procedures in both diagnosing and in select cases, treating the painful joint arthroplasty. Topics to be discussed in this article include trends in arthroplasty placement, benefits of the use of ultrasound overall, and ultrasound evaluation of periprosthetic joint infections. We will also review the sonographic findings with dissociated/displaced components and adverse reaction to metallic debris including metallosis, trunnionosis, and metal-on-metal pseudotumors. Additionally, we will discuss ultrasound evaluation of tendon pathologies with arthroplasties, including dynamic maneuvers to evaluate for tendon impingement/snapping. Finally, we will cover ultrasound-guided joint arthroplasty injection indications and precautions. KEY POINTS: • Ultrasound is preferred over MRI in patients with joint arthroplasty and plays a crucial role in diagnosis, especially given its unique dynamic capabilities, convenience and high resolution. • It is especially beneficial for US-guided aspiration in periprosthetic joint infections; effectively used to evaluate periprosthetic fluid collections, facilitating differentiation between abscesses and aseptic collections, and tracking sinus tracts. • Recently, the diagnosis of periprosthetic joint infections has shifted focus to biomarkers in the periprosthetic fluid, specifically α-defensin, which has a high sensitivity and specificity for diagnosing infection. • Cutibacterium acnes is a major pathogen responsible for shoulder arthroplasty infections, often presenting with normal laboratory values and since slow growing, must be kept for a minimum of 14 days.

Injection of adipose stem cells in the treatment of rotator cuff disease - a narrative review of current evidence.

The purpose of this study is to summarize evidence for the use of adipose stem cell (ASC) injections in the treatment of rotator cuff tears (RCT) and identify future areas of study. A thorough literature search was performed to identify studies investigating the use of ASC injections in the treatment of RCTs. Among animal trials, it is unclear whether ASCs are of benefit for rotator cuff repair. In clinical trials, ASC injection may reduce retear rate with otherwise equivocal clinical outcomes. Although ASC injection may be safe, the literature does not provide a clear consensus as to the efficacy of ASC injections, nor does it delineate which patients would benefit most from this treatment.

The purpose of this paper is to review available studies that look at the effects of adipose stem cell (ASC) injections in the treatment of rotator cuff tears (RCT). A thorough literature search of all available studies was performed. Among lab studies in animals, it is unclear if ASCs help improve the outcomes of rotator cuff repair. In studies using live patients, ASC injection may reduce retear rate, but it is unclear whether there are any other benefits to ASC injection. ASC injection is safe in humans, but the literature does not provide a clear consensus as to how much benefit this treatment provides for rotator cuff repair, nor does it delineate which patients would benefit most from this treatment.

Preoperative Opioid Use Is Associated With Inferior Patient-Reported Outcomes Measurement Information System Scores Following Rotator Cuff Repair.

PURPOSE: To determine the influence of preoperative opioid use on Patient-Reported Outcomes Measurement Information System (PROMIS) scores pre- and postoperatively in patients undergoing arthroscopic rotator cuff repair (RCR). METHODS: A retrospective review of all RCR patients aged >18 years old was performed. PROMIS pain interference ("PROMIS PI"), upper extremity function ("PROMIS UE"), and depression ("PROMIS D") scores, were reviewed. These measures were collected at preoperative, 6-month, and 1-year postoperative time points. A prescription drug-monitoring program was queried to track opioid prescriptions. Patients were categorized as chronic users, acute users, and nonusers based on prescriptions filled. Comparison of means were carried out using analysis of variance and least squares means. Effect sizes and 95% confidence intervals were calculated. RESULTS: In total, 184 patients who underwent RCR were included. Preoperatively, nonusers (n = 92) had superior PROMIS UE (30.6 vs 28.9 vs 26.1; P < .05) and PI scores (61.5 vs 64.9 vs 65.3; P < .001) compared with acute users (n = 65) and chronic users (n = 27), respectively. At 6 months postoperatively; nonusers demonstrated significantly greater PROMIS UE (41.7 vs 35.6 vs. 33.5; P < .001), lower PROMIS D (41.6 vs 45.8 vs 51.1; P < .001), and lower PROMIS PI scores (50.7 vs 56.3 vs 58.1; P < .01) when compared with acute and chronic users, respectively. Nonusers had lower PROMIS PI (47.9 vs 54.3 vs 57.4; P < .0001) and PROMIS D (41.6 vs 48.3 vs 49.2; P = .0002) scores compared with acute and chronic users at 1-year postoperatively. Nonusers experienced a significantly greater magnitude of improvement in PROMIS D 6 months postoperatively compared with chronic opioid users (-5.9 vs 0.0; P < .01). CONCLUSIONS: Patients undergoing RCR demonstrated superior PROMIS scores pre- and postoperatively if they did not use opioids within 3 months before surgery. LEVEL OF EVIDENCE: III, retrospective comparative trial.

Risk factors for failure to achieve minimal clinically important difference and significant clinical benefit in PROMIS computer adaptive test domains in patients undergoing rotator cuff repair.

BACKGROUND: The Patient-Reported Outcomes Measurement Information System (PROMIS) has emerged as a valid and efficient means of collecting outcomes in patients with rotator cuff tears. The purpose of this study was to establish threshold score changes to determine minimal clinically important difference (MCID) and substantial clinical benefit (SCB) in PROMIS computer adaptive test (CAT) scores following rotator cuff repair (RCR). Additionally, we sought to identify potential risk factors for failing to achieve MCID and SCB. METHODS: Patients undergoing arthroscopic RCR were identified over a 24-month period. Only patients who completed both preoperative and postoperative PROMIS CAT assessments were included in this cohort. PROMIS CAT forms for upper extremity physical function (PROMIS-UE), pain interference (PROMIS-PI), and depression (PROMIS-D) were used with a minimum of 1.5-year follow-up. Statistical analysis was performed to determine threshold score changes to determine anchor-based MCID and SCB, as well as risk factors for failure to achieve significant clinical improvement following surgery. RESULTS: Of 198 eligible patients, 168 (84.8%) were included in analysis. ΔPROMIS-UE values of 5.8 and 9.7 (area under the curve [AUC] = 0.906 and 0.949, respectively) and ΔPROMIS-PI values of -11.4 and -12.9 (AUC = 0.875 and 0.938, respectively) were identified as threshold predictors of MCID and SCB achievement. On average, 81%, 65%, and 55% of patients achieved MCID for PROMIS-UE, PROMIS-PI, and PROMIS-D whereas 71%, 61%, and 38% of patients in the cohort, respectively, achieved SCB. MCID achievement in PROMIS-UE significantly differed according to risk factors, including smoking status (likelihood ratio [LR]: 9.8, P = .037), tear size (LR: 10.4, P < .001), distal clavicle excision (LR: 6.1, P = .005), and prior shoulder surgery (LR: 19.2, P < .001). Factors influencing SCB achievement for PROMIS-UE were smoking status (LR: 9.3, P = .022), tear size (LR: 8.0, P = .039), and prior shoulder surgery (11.9, P < .001). Significantly different rates of MCID and SCB achievement in PROMIS-PI for smoking status (LR: 7.0, P = .030, and LR: 5.2, P = .045) and prior shoulder surgery (LR: 9.1, P = .002, and LR: 7.4, P = .006) were also identified. DISCUSSION AND CONCLUSION: The majority of patients showed clinically significant improvements that exceeded the established MCID for PROMIS-UE and PROMIS-PI following RCR. Patients with larger tear sizes, a history of prior shoulder surgery, tobacco users, and those who received concomitant distal clavicle excision were at risk for failing to achieve MCID in PROMIS-UE. Additionally, smokers and patients who underwent prior shoulder surgery demonstrated significantly lower improvements in pain scores following surgery.

Patient-Reported Outcomes Measurements Information System (PROMIS) upper extremity and pain interference do not significantly predict rotator cuff tear dimensions.

BACKGROUND: Proper diagnosis of rotator cuff tears is typically established with magnetic resonance imaging (MRI); however, studies show that MRI-derived measurements of tear severity may not align with patient-reported pain and shoulder function. The purpose of this study is to investigate the capacity for the Patient-reported Outcomes Measurements Information System (PROMIS) computer adaptive tests to predict rotator cuff tear severity by correlating preoperative tear morphology observed on MRI with PROMIS upper extremity (UE) and pain interference (PI) scores. This is the first study to investigate the relationship between tear characteristics and preoperative patient-reported symptoms using PROMIS. Considering the essential roles MRI and patient-reported outcomes play in the management of rotator cuff tears, the findings of this study have important implications for both treatment planning and outcome reporting. METHODS: Two PROMIS-computer adaptive test forms (PROMIS-UE and PROMIS-PI) were provided to all patients undergoing rotator cuff repair by one of three fellowship-trained surgeons at a single institution. Demographic information including age, sex, race, employment status, body mass index, smoking status, zip code, and preoperative PROMIS-UE and -PI scores was prospectively recorded. A retrospective chart review of small to large full- or partial-thickness rotator cuff tears between May 1, 2017 and February 27, 2019 was used to collect each patient's MRI-derived tear dimensions and determine tendon involvement. RESULTS: Our cohort consisted of 180 patients (56.7% male, 43.3% female) with an average age of 58.9 years (standard deviation, 9.0). There was no significant difference in PROMIS-UE or -PI scores based on which rotator cuff tendons were involved in the tear (P > .05). Neither PROMIS-UE nor PROMIS-PI significantly correlated with tear length or retraction length of the supraspinatus tendon (P > .05). The sum of tear lengths in the anterior-posterior and medial-lateral directions was weakly correlated with PROMIS-UE (P = .042; r = -0.152, r2 = 0.031) and PROMIS-PI (P = .027; r = 0.165, r2 = 0.012). CONCLUSION: Rotator cuff tear severity does not significantly relate to preoperative PROMIS-UE and -PI scores. This finding underscores the importance of obtaining a balanced preoperative assessment of rotator cuff tears that acknowledges the inconsistent relationship between rotator cuff tear characteristics observed on MRI and patient-reported pain and physical function.

Characterizing preoperative expectations for patients undergoing reverse total shoulder arthroplasty.

BACKGROUND: There remains a paucity of information analyzing which factors most influence preoperative expectations for patients undergoing reverse total shoulder arthroplasty (RTSA). The purposes of our study were to characterize preoperative patient expectations for those scheduled to undergo RTSA and to determine the impact of demographic factors, shoulder function, and shoulder pain on these preoperative expectations. METHODS: Patients were prospectively recruited into the study if they were scheduled to undergo an elective unilateral primary RTSA for a diagnosis of glenohumeral arthritis. Preoperative patient expectations were evaluated using the Hospital for Special Surgery's Shoulder Surgery Expectation Survey. Patients also completed the American Shoulder and Elbow Surgeons shoulder score, the Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function-Upper Extremity computer adaptive test (version 2.0), the PROMIS Pain Interference (PI) computer adaptive test (version 1.1), the PROMIS Depression computer adaptive test (version 1.0), visual analog scores, and an itemized satisfaction questionnaire, which paralleled the Hospital for Special Surgery's Shoulder Surgery Expectation Survey. Demographic data and preoperative shoulder range of motion (ROM) were also recorded. RESULTS: A total of 107 patients scheduled to undergo RTSA were included in the study. Relief of daytime pain (n = 91, 85%), improvement in self-care (n = 86, 80%), and improvement in shoulder ROM (n = 85, 79%) were most commonly cited as "very important" expectations. In the item-specific analysis, lower PROMIS Upper Extremity scores were correlated with greater expectations for the ability to reach sideways (P = .015) and the ability to perform daily activities (P = .018). Patients with lower shoulder ROM had greater expectations for improved shoulder ROM (internal rotation with arm at 90°, P = .004) and an improved ability to perform daily activities (forward elevation, P = .038; abduction, P = .009). In the cumulative analysis, a greater number of very important expectations was associated with African American race (P = .013), higher PROMIS PI score (r = 0.351, P = .004), and lower overall preoperative satisfaction (r = 0.334, P < .001). CONCLUSION: Patients scheduled to undergo RTSA have the greatest expectations for relief of daytime pain, improvement in self-care, and improvement in shoulder ROM. Patients with limited preoperative ROM have greater expectations for improvement in self-care and the ability to perform daily activities in addition to expectations for improvement in shoulder ROM. Greater overall expectations for surgery were not associated with preoperative physical function but were instead associated with lower preoperative satisfaction and higher PROMIS PI scores.

Trends in Patient-Reported Outcomes Measurement Information System Scores Exist Between Day of Surgical Scheduling and Day of Surgery.

PURPOSE: To examine trends in Patient-Reported Outcome Measurement Information System (PROMIS) scores among orthopedic sports medicine patients undergoing surgery who completed PROMIS forms both in the ambulatory (preoperative) setting at the time of surgical scheduling, as well as on the day of surgery (perioperative) prior to their procedure. METHODS: Consecutive patients undergoing various sports medicine-related surgeries were recruited. Patients were included if they were scheduled for surgery and completed preoperative PROMIS on the day of surgical scheduling and on the day of surgery. Patients were excluded if they refused the questionnaire or had been administered perioperative anesthesia, which would interfere with questionnaire completion. Paired samples t-tests were run between preoperative and perioperative PROMIS scores to determine statistical significance. RESULTS: 153 patients were included with an average age of 46.5 years. The average (SD) time between completion of PROMIS questionnaires was 46.5 (44.4) days. The absolute value change in scores between preoperative and perioperative visits was 4.09 for PROMIS UE, 3.59 for PROMIS PF, 3.67 for PROMIS PI, and 4.13 for PROMIS D. The overall net change of scores between preoperative and perioperative visits were -.57 for PROMIS UE CAT, .16 points for PROMIS PF CAT, -.85 points for PROMIS PI CAT, and -2.14 points for PROMIS D CAT. Statistically significant differences in preoperative and perioperative PROMIS PI (P =.042) and PROMIS D (P =.004) scores were found. CONCLUSIONS: Health states-as measured by PROMIS CAT forms completed among patients undergoing orthopedic surgery-can either improve or worsen preoperatively between the time of administration in both the ambulatory and perioperative setting. Despite the existence of these preoperative trends, it is important to consider patient and surgery-specific causes, such as the anatomic region, type of surgical intervention, and timing of preoperative PROMIS administration. LEVEL OF EVIDENCE: III, prognostic.

The impact of external beam radiation therapy on shoulder surgical outcomes: a case series study.

HYPOTHESIS: External beam radiation therapy (XRT) is a commonly used treatment adjunct in patients with breast cancer and is known to cause soft tissue dysfunction. However, data on XRT as a preoperative risk factor for shoulder surgery is limited. The purpose of this study was to assess whether prior history of breast cancer treated with XRT has an impact on surgical complications or outcomes. We hypothesize that patients treated with XRT will have a higher rate of surgical complications and lower outcomes. METHODS: A 20-year retrospective chart review across a large, academic health care system was performed. Inclusion criterion comprised any patient with history of breast cancer of the upper-outer or axillary region treated with XRT. Patients also must have undergone a surgical procedure to the ipsilateral shoulder with at least 1-year postoperative follow-up. Patients were stratified by demographics, hand dominance, and surgery type. Postoperative outcomes including range of motion (ROM) and visual analog scale (VAS) scores for pain were also collected. RESULTS: Eighteen patients were identified (100% female) with an average age of 66.3 years (standard deviation 10.5 years). Ten shoulders underwent rotator cuff repair (RCR), 4 total shoulder arthroplasty (TSA), 3 reverse shoulder arthroplasty (RSA), and 1 arthroscopic superior labrum anterior to posterior (SLAP) repair. Four patients treated with RCR (40%) experienced postoperative complications related to their procedure. These included scapular winging, adhesive capsulitis, stiffness, and one retear. Two patients treated with shoulder arthroplasty (28.6%) experienced postoperative complications that included lymphedema and periprosthetic fracture following a mechanical fall in one RSA patient and periprosthetic infection in a TSA patient. ROM across all groups improved, most significantly in forward flexion and internal rotation among RCR patients (P < .001). Furthermore, a statistically significant improvement in VAS scores was achieved in each group (6.2 ± 2.14 preoperation, 1.06 ± 1.75 postoperation; P < .001). CONCLUSION: When compared to national averages, complication rates in our cohort were higher (40% vs. 10%-17% in RCR patients and 28.6% vs. 4%-14% in arthroplasty patients). On further scrutiny, many of these complications were independent of a history of XRT and many resolved with appropriate therapy. Most importantly, functional outcomes as measured by ROM and pain scores showed appropriate improvement consistent with normal populations without history of XRT. Thus, our results suggest that performing shoulder surgery after ipsilateral XRT for breast cancer is likely safe and may offer improved pain and ROM compared to forgoing surgery without necessarily increasing the risk for postoperative complication.

Does the use of periarticular anesthetic cocktail provide adequate pain control following shoulder arthroplasty?

BACKGROUND: Interscalene nerve block and liposomal bupivacaine have been found to provide adequate pain control following shoulder arthroplasty. We hypothesized that local infiltration of a periarticular cocktail would provide equivalent pain control compared to interscalene nerve block and liposomal bupivacaine. METHODS: Eighty-seven patients undergoing primary shoulder arthroplasty were treated with local infiltration of a periarticular cocktail (200 mg of 0.5% ropivacaine, 1 mg epinephrine, and 30 mg ketorolac), local infiltration of liposomal bupivacaine, or preoperative interscalene nerve block. The outcomes of the study were postoperative visual analog scale scores, opioid consumption, length of stay, and complications. RESULTS: A total of 30 patients receiving local infiltration of a periarticular cocktail, 26 receiving liposomal bupivacaine, and 31 receiving interscalene nerve block were included in the study. Patients who received local infiltration of a periarticular cocktail had a significantly lower mean visual analog scale when compared to interscalene nerve block and liposomal bupivacaine on postoperative day 0 (2.5 versus 4.0 versus 4.8, P = 0.001 and P < 0.001). Pain scores between postoperative day 0-3 were lower in patients who received local infiltration of a periarticular cocktail, but not significantly. Patients who received local infiltration of a periarticular cocktail required significantly less opioids than the interscalene nerve block group on postoperative day 0 (P < 0.001). DISCUSSION: A decrease in early postoperative pain and opioid consumption was found with local infiltration of a periarticular cocktail when compared with interscalene nerve block and liposomal bupivacaine after shoulder arthroplasty.Level of evidence: Level II.

Return to Golf Following Reverse Total Shoulder Arthroplasty.

BACKGROUND: The object of this study was to examine return to golf and changes in golf performance after shoulder arthroplasty. Additionally, we set out to determine if there were differences in return to play and performance between total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RTSA). We also examined pain during the golf swing to determine if there is a change in pain level after surgery. METHODS: Patients were identified using a Current Procedural Terminology code 23472 search for TSA. A 19-question online survey was sent out to each patient with questions detailing golfing performance and pain during the swing before and after surgery. Comparisons were made to determine differences in pain, performance and enjoyment between TSA and RTSA groups before and after surgery. RESULTS: A total of 586 patients who underwent shoulder arthroplasty were sent the online survey via email. Of those patients, 33 identified themselves as golfers and who responded to the survey, resulting in an overall response rate of 5.6%. Twenty-three of 31 (74%) patients were able to return to golf following their procedure. Overall, the respondents who reported pain associated with golfing activity had significantly decreased pain after undergoing either TSA or RTSA. The RTSA group had a significant drop in driving distance following the procedure and this was significantly lower than the postoperative driving distance in the TSA group, despite an insignificant preoperative difference. CONCLUSION: Overall, TSA offers a safe and effective means for reducing pain during the golf swing in patients suffering from advanced shoulder osteoarthritis. While there were no significant changes in performance following TSA, individuals undergoing RTSA can be counseled that they are at risk for lower driving distances due to altered mechanics. Overall, patients were satisfied with their procedure and their ability to return to the golf course.

Simultaneous, Ipsilateral Distal Biceps and Distal Triceps Rupture in Healthy Weight Lifter: A Case Report.

CASE: A 38-year-old weight lifter presented with a complete distal biceps rupture with retraction and a near complete ipsilateral distal triceps tear sustained during the bench press exercise. The tendons were fixed operatively using a simultaneous posterior and anterolateral approach to the elbow. CONCLUSION: Simultaneous, ipsilateral distal biceps and distal triceps tendon injury is a rare occurrence that leads to significant functional loss. Repair of distal biceps rupture using a single-incision technique with a cortical button and distal triceps using a double-row suture anchor repair was successful in restoring functional anatomy to our patient.

Ultrasound shear wave elastography and its association with rotator cuff tear characteristics.

BACKGROUND: Approximately 20-60% of rotator cuff repairs fail with higher failure rates in patients with larger or more chronic tears. Although MRI provides an objective estimate of tear size, it can only provide qualitative descriptions of tear chronicity. By contrast, ultrasound shear wave elastography (SWE) may assess tear chronicity by estimating tissue mechanical properties (ie, shear modulus). Furthermore, SWE imaging does not share many of the challenges associated with MRI (eg, high cost, risk of claustrophobia). Therefore, the objective of this study was to determine the extent to which estimated supraspinatus shear modulus is associated with conventional MRI-based measures of rotator cuff tear size and chronicity. METHODS: Shear modulus was estimated using ultrasound SWE in two regions of the supraspinatus (intramuscular tendon, muscle belly) under two contractile conditions (passive, active) in 22 participants with full-thickness rotator cuff tears. The extent to which estimated supraspinatus shear modulus is associated with conventional MRI measures of tear size and chronicity was assessed using correlation coefficients and Kruskal-Wallis tests, as appropriate. RESULTS: Estimated shear modulus was not significantly associated with anterior/posterior tear size (P > .09), tear retraction (P > .20), occupation ratio (P > .11), or fatty infiltration (P > .30) under any testing condition. DISCUSSION: Although ultrasound SWE measurements have been shown to be altered in the presence of various tendinopathies, the findings of this study suggest the utility of ultrasound SWE in this population (ie, patients with a small to medium supraspinatus rotator cuff tear) before surgical rotator cuff repair remains unclear.

Patients With Preoperative Clinical Depression Symptomology Experience Significant Improvements in Postoperative Pain, Function, and Depressive Symptoms Following Rotator Cuff Repair.

PURPOSE: To determine the impact of clinical depression on outcomes after rotator cuff repair (RCR), as measured by Patient-Reported Outcomes Measurement Information System (PROMIS) Computer Adaptive Test (CAT) health domains. METHODS: RCR patients were given PROMIS CAT assessments for physical function (PROMIS UE), pain interference (PROMIS PI), and depression (PROMIS D) during preoperative and postoperative clinic visits. PROMIS D scores ≥55 correlate with mild clinical depression; thus patients with PROMIS D scores ≥ 55 were placed in the clinical depression (CD) group, whereas patients with scores <55 were placed in the "no clinical depression" (NCD) group. Categorical variables were compared at preoperative and postoperative (6 months and ≥1 year) timepoints using χ2 tests. Continuous variables were compared using Student's t-tests. RESULTS: Of the 340 RCR patients included in this study, 65 (19.1%) were found to have mild clinical depression preoperatively, with that number being reduced to 23 (6.8%) at 6 months and 19 (5.6%) at ≥1 year after surgery. Compared with preoperative PROMIS scores, CD patients had significant postoperative improvements at 6 months and ≥1 year in mean PROMIS UE (26.7 vs 35.5 vs 38.9; P < .001) and PROMIS PI (67.6 vs 56.7 vs 56.4; P < .001). NCD patients had similar postoperative improvements at 6 months and ≥1 year in mean PROMIS UE (30.8 vs 38.6 vs 46.9; P < .001) and PROMIS PI (61.7 vs 53.0 vs 47.6; P < .001). The improvement in PROMIS scores was similar for the CD and NCD groups in both PROMIS UE (12.2 vs 16.1, respectively) and PROMIS PI (-11.2 vs -14.1, respectively). CONCLUSION: Despite starting with worse PROMIS UE and PROMIS PI scores, patients undergoing RCR with symptoms of CD experienced significant improvement in function, pain, and depressive symptoms. Preoperative depression should not be a contraindication to arthroscopic RCR in patients who are otherwise appropriate operative candidates. LEVEL OF EVIDENCE: Level III, retrospective comparative trial.
