PROMIS physical function and pain perform poorly psychometrically in patients undergoing medial patellofemoral ligament reconstruction.

PURPOSE: The purpose of this study was to assess the validity, floor and ceiling effects, and dimensionality of PROMIS Physical Function (PF) and Pain compared to legacy patient reported outcome (PRO) measures in patients undergoing medial patellofemoral ligament (MPFL) reconstruction. METHODS: Patients who underwent MPFL reconstruction between 2018 to 2020 were retrospectively reviewed. Preoperatively, patients completed the IKDC, VR-12, Kujala, SF-12, KOOS JR, PROMIS PF and Pain surveys. Inter-survey convergence was assessed with Spearman correlations. Psychometric analysis included investigations of inter-survey convergent validity, intra-survey floor and ceiling effects, and Rasch analyses with person-item fit and iterative question elimination model fit testing. RESULTS: A total of 76 patients (mean age: 22.6 ± 8.4 years) who completed preoperative surveys were included (compliance: 91.7-96.2%). Preoperatively, age was significantly associated with both PROMIS PF (coefficient: - 0.291, P = 0.005) and Pain scores (coefficient: 0.294, P = 0.002). PROMIS PF had a Very Good correlation with IKDC and PROMIS Pain had a Very Good correlation with KOOS JR. Other correlations ranged from Poor to Good. No significant floor or ceiling effects were observed for any PRO. On iterative question elimination Rasch modelling, only two questions from PROMIS PF remained after 6 rounds of elimination while PROMIS Pain had no questions remaining after 3 rounds of elimination. CONCLUSION: Preoperative PROMIS PF and Pain provided only Fair to Good correlations with most legacy PROs. Although no significant floor and ceiling effects were observed, PROMIS PF and Pain did not perform well psychometrically in this population of patients undergoing MPFL reconstruction. These results suggest PROMIS questionnaires should be used with caution in this population, especially if used in isolation, when discussing clinical expectations with patients. The authors recommend continued use of legacy PROs specific to assessment of patellar instability and function that have established validity in patellar instability populations.

Costs of shoulder and elbow procedures are significantly reduced in ambulatory surgery centers compared to hospital outpatient departments.

BACKGROUND: Recent literature has shown the advantages of outpatient surgery for many shoulder and elbow procedures, including cost savings with equivalent safety in appropriately selected patients. Two common settings for outpatient surgeries are ambulatory surgery centers (ASCs), which function as independent financial and administrative entities, or hospital outpatient departments (HOPDs), which are owned and operated by hospital systems. The purpose of this study was to compare shoulder and elbow surgery costs between ASCs and HOPDs. METHODS: Publicly available data from 2022 provided by the Centers for Medicare & Medicaid Services (CMS) was accessed via the Medicare Procedure Price Lookup Tool. Current Procedural Terminology (CPT) codes were used to identify shoulder and elbow procedures approved for the outpatient setting by CMS. Procedures were grouped into arthroscopy, fracture, or miscellaneous. Total costs, facility fees, Medicare payments, patient payment (costs not covered by Medicare), and surgeon's fees were extracted. Descriptive statistics were used to calculate means and standard deviations. Cost differences were analyzed using Mann-Whitney U tests. RESULTS: Fifty-seven CPT codes were identified. Arthroscopy procedures (n = 16) at ASCs had significantly lower total costs ($2667 ± $989 vs. $4899 ± $1917; P = .009), facility fees ($1974 ± $819 vs. $4206 ± $1753; P = .008), Medicare payments ($2133 ± $791 vs. $3919 ± $1534; P = .009), and patient payments ($533 ± $198 vs. $979 ± $383; P = .009) compared with HOPDs. Fracture procedures (n = 10) at ASCs had lower total costs ($7680 ± $3123 vs. $11,335 ± $3830; P = .049), facility fees ($6851 ± $3033 vs. $10,507 ± $3733; P = .047), and Medicare payments ($6143 ± $2499 vs. $9724 ± $3676; P = .049) compared with HOPDs, although patient payments were not significantly different ($1535 ± $625 vs. $1610 ± $160; P = .449). Miscellaneous procedures (n = 31) at ASCs had lower total costs ($4202 ± $2234 vs. $6985 ± $2917; P < .001), facility fees ($3348 ± $2059 vs. $6132 ± $2736; P < .001), Medicare payments ($3361 ± $1787 vs. $5675 ± $2635; P < .001), and patient payments ($840 ± $447 vs. $1309 ± $350; P < .001) compared with HOPDs. The combined cohort (n = 57) at ASCs had lower total costs ($4381 ± $2703 vs. $7163 ± $3534; P < .001), facility fees ($3577 ± $2570 vs. $6539.1 ± $3391; P < .001), Medicare payments ($3504 ± $2162 vs. $5892 ± $3206; P < .001), and patient payments ($875 ± $540 vs. $1269 ± $393; P < .001) compared with HOPDs. CONCLUSION: Shoulder and elbow procedures performed at HOPDs for Medicare recipients were found to have average total cost increase of 164% compared with those performed at ASCs (184% savings for arthroscopy, 148% for fracture, and 166% for miscellaneous). ASC use conferred lower facility fees, patient payments, and Medicare payments. Policy efforts to incentivize migration of surgeries to ASCs may translate into substantial health care cost savings.

Physical Therapy Combined With Subacromial Cortisone Injection Is a First-Line Treatment Whereas Acromioplasty With Physical Therapy Is Best if Nonoperative Interventions Fail for the Management of Subacromial Impingement: A Systematic Review and Network Meta-Analysis.

PURPOSE: To construct an algorithm to optimize clinical outcomes in subacromial impingement based on current, high-level evidence. METHODS: A systematic review of all clinical trials on subacromial impingement published from 1999 to 2020 was performed. Demographic, clinical, range of motion (ROM), and patient-reported outcome measure (PROM) data were collected. Interventions were compared via arm-based Bayesian network meta-analysis in a random-effects model and treatments ranked via surface under the cumulative ranking curves with respect to 3 domains: pain, PROMs, and ROM. RESULTS: A total of 35 studies comprising 3,643 shoulders (42% female, age 50 ± 5 years) were included. Arthroscopic decompression with acromioplasty ranked much greater than arthroscopic decompression alone for pain relief and PROM improvement, but the difference in absolute PROMs was not statistically significant. Corticosteroid injection (CSI) alone demonstrated inferior outcomes across all 3 domains (pain, PROMs, and ROM) with low cumulative rankings. Physical therapy (PT) with CSI demonstrated moderate-to-excellent clinical improvement across all 3 domains whereas PT alone demonstrated excellent ROM and low-moderate outcomes in pain and PROM domains. PT with nonsteroidal anti-inflammatory drugs or alternative therapies ranked highly for PROM outcomes and moderate for pain and ROM domains. Finally, platelet-rich plasma injections demonstrated moderate outcomes for pain, forward flexion, and abduction with very low-ranking outcomes for PROMs and external rotation. CONCLUSIONS: Arthroscopic decompression with acromioplasty and PT demonstrated superior outcomes whereas CSI demonstrated poor outcomes in all 3 domains (pain, PROMs, and ROM). For patients with significant symptoms, the authors recommend PT with CSI as a first-line treatment, followed by acromioplasty and PT if conservative treatment fails. For patients with symptoms limited to 1 to 2 domains, the authors recommend a shared decision-making approach focusing on treatment rankings within domains pertinent to individual patient symptomatology.

Double-Row Repair With Platelet-Rich Plasma Optimizes Retear Rates After Small to Medium Full-Thickness Rotator Cuff Repair: A Systematic Review and Network Meta-analysis of Randomized Controlled Trials.

PURPOSE: To compare the different interventions described in the literature for the surgical treatment of small and medium complete rotator cuff tears. METHODS: A systematic review of randomized controlled trials of small-medium, full-thickness rotator cuff tears published since 2000 was performed. Clinical characteristics, re-tear rates, range of motion (ROM), and patient-reported outcomes (PRO) data were collected. Interventions were compared via arm-based Bayesian network meta-analysis in a random-effects model. Interventions were ranked for each domain (re-tear risk, pain, ROM, and PROs) via surface under the cumulative ranking curves. RESULTS: A total of 18 studies comprising 2046 shoulders (47% females, mean age 61 ± 3 years, mean follow-up 21 ± 5 months) were included. Interventions that ranked highest for minimizing re-tear risk included arthroscopic single-row repair (A+SR) or double-row repair (A+DR) with or without platelet-rich plasma (PRP). Open repair and A+SR repair with acromioplasty (ACP) ranked highest for pain relief. Interventions that ranked highest for ROM improvement included open repair, PT, and A+DR with or without ACP. Interventions that ranked highest for PROs included arthroscopic footprint microfracture with or without SR, open repair, and A+SR with or without ACP. CONCLUSIONS: Based on a network meta-analysis of level 1 studies, arthroscopic rotator cuff repair with a SR or DR construct demonstrates similar retear rates, PROs, and clinical outcomes. The highest-ranking treatment for minimizing retears was arthroscopic repair with DR constructs and PRP augmentation, although open repair and arthroscopic SR remain reliable options with excellent clinical outcomes. Addition of PRP to DR constructs trended toward a 56% decreased risk of retear as compared to DR repair alone. Although no single treatment emerged superior, several interventions offered excellent clinical improvements in pain, ROM, and PROs that exceeded minimal clinically important difference thresholds.

Two-Year Clinical Outcomes and Survivorship After Isolated Biceps Tenodesis.

PURPOSE: The purpose of this study was to evaluate clinical outcomes and survivorship of isolated biceps tenodesis (BT) at a minimum of 2 years and to identify patient-specific factors associated with these outcomes in patients undergoing BT without concomitant rotator cuff repair (RCR). We hypothesized that patient-reported outcomes would be significantly improved on American Shoulder and Elbow Surgeons Survey (ASES) and Single Assessment Numeric Evaluation (SANE), with a high rate of survivorship (>90%) at 2-year follow-up. METHODS: A retrospective review of an institutional registry was performed to identify patients who underwent BT from July 2016 to December 2017. Patients >18 years old who underwent an open or arthroscopic BT procedure using an interference screw, button, or anchor for underlying bicipital pathology, without a concomitant RCR or shoulder arthroplasty, and were a minimum of 2 years postoperative were included. Patients were administered ASES and SANE questionnaires preoperatively and at final follow-up. Survivorship was evaluated using Kaplan-Meier analysis. Failure was defined as any patient who underwent reoperation related to the index surgery. RESULTS: A total of 110 patients (mean ± standard deviation age, 48.60 ± 12.14 years) who underwent isolated BT with a follow-up of 24.90 ± 3.95 months were included in analysis. There was a significant improvement in ASES and SANE at final follow-up (P < .001), with 81% to 84% of patients achieving minimal clinically important difference (MCID), 72% to 82% achieving substantial clinical benefit (SCB), and 72% to 80% achieving patient-acceptable symptom state (PASS). Worker's Compensation (WC) patients had a decreased likelihood of achieving PASS on ASES (P = .015) and SANE (P = .012). Four cases were deemed failures (3 revision BTs and 1 capsular debridement) at 15.09 ± 9.57 months. WC did not have a significant effect on likelihood of BT failure. CONCLUSION: Biceps tenodesis provided significant clinical improvement and high rates of survivorship 2 years postoperatively. WC was associated with a decreased likelihood of achieving PASS. These results support the continued use of isolated BT for treating biceps pathology. LEVEL OF EVIDENCE: IV, case series.

An evidence-based approach to managing unexpected positive cultures in shoulder arthroplasty.

BACKGROUND: Unexpected positive cultures (UPCs) are very commonly found during shoulder arthroplasty when surgeons send intraoperative cultures to rule out periprosthetic joint infection (PJI) without clinical or radiographic signs of infection. Cutibacterium acnes is thought to be the most common bacteria cultured in this setting; however, the implications of an unexpected positive result are neither well defined nor agreed upon within the literature. The current review evaluates the incidence of UPCs and C acnes in reverse total arthroplasty; the clinical significance, if any, of these cultures; and various prognostic factors that may affect UPC incidence or recovery following PJI. METHODS: A systematic review was performed with PRISMA guidelines using PubMed, CINAHL, and Scopus databases. Inclusion criteria included studies published from January 1, 2000, to May 20, 2021, that specifically reported on UPCs, native or revision shoulder surgery, and any study that directly addressed one of our 6 proposed clinical questions. Two independent investigators initially screened 267 articles for further evaluation. Data on study design, UPC rate/speciation, UPC risk factors, and UPC outcomes were analyzed and described. RESULTS: A total of 22 studies met the inclusion criteria for this study. There was a pooled rate of 27.5% (653/2373) deep UPC specimen positivity, and C acnes represented 76.4% (499/653) of these positive specimens. Inanimate specimen positivity was reported at a pooled rate of 20.1% (29/144) across 3 studies. Male patients were more likely to have a UPC; however, the significance of prior surgery, surgical approach, and type of surgery conflicted across multiple articles. Patient-reported outcomes and reoperation rates did not differ between positive-UPC and negative-UPC patients. The utilization of antibiotics and treatment regimen varied across studies; however, the reinfection rates following surgery did not statistically differ based on the inclusion of antibiotics. CONCLUSION: UPCs are a frequent finding during shoulder surgery and C acnes represents the highest percentage of cultured bacteria. Various preoperative risk factors, surgical techniques, and postoperative treatment regimens did not significantly affect the incidence of UPCs as well as the clinical outcomes for UPC vs. non-UPC patients. A standardized protocol for treatment and follow-up would decrease physician uncertainty when faced with a UPC from shoulder surgery. Given the results of this review, shoulder surgeons can consider not drastically altering the postoperative clinical course in the setting of UPC with no other evidence of PJI.

PROMIS Upper Extremity underperforms psychometrically relative to American Shoulder and Elbow Surgeons score in patients undergoing primary rotator cuff repair.

BACKGROUND: A number of patient-reported outcome measure (PROM) instruments are used to assess shoulder pain, function, and postoperative satisfaction. Computer adaptive tests (CATs) have been developed in an effort to tailor question delivery, decrease time to completion and floor/ceiling effects, and increase compliance. Previous investigations have demonstrated excellent correlation between Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity CAT (UE-CAT) and American Shoulder and Elbow Surgeons (ASES) instruments, indicating that the PROMIS UE-CAT may be an acceptable alternative to the ASES. Prior to widespread adoption, however, rigorous psychometric validation must be performed. Thus, the purpose of this study was to evaluate the psychometric properties of PROMIS UE-CAT relative to the ASES score in patients undergoing primary rotator cuff repair (RCR). METHODS: A retrospective study of an institutional RCR registry was performed from July 2018 through March 2019. Preoperative PROMIS UE-CAT and ASES scores were collected. Floor and ceiling effects were determined, and convergent validity was established through Pearson correlations. Rasch partial credit modeling was used for psychometric analysis of the validity of PROMIS UE-CAT and ASES question items, a previously established methodology for assessing shoulder PROMs. Person-item maps were generated to characterize the distribution of question responses along the latent dimension of shoulder disability. RESULTS: Responses from 107 patients (107 shoulders) were included. PROMIS UE-CAT had a strong correlation to ASES (r = 0.684; P < .001), with a 3.7% floor effect and no ceiling effect; ASES had no floor or ceiling effects. PROMIS UE-CAT person-item maps revealed excellent test item coverage between floor and ceiling effects; however, all PROMIS UE-CAT items except "Difficulty putting on a jacket" demonstrated nonsequentially ordered responses, indicating poor reliability of item responses corresponding to shoulder function. Although PROMIS UE-CAT initially demonstrated superior instrument efficiency with fewer test items for overall equivalent coverage of shoulder function assessment, final models after recursive item elimination revealed the ASES instrument to have more well-fitting items over a broader range of shoulder function. CONCLUSION: Despite its overall strong correlation with ASES and equivalent coverage between floor and ceiling effects, the psychometric properties of PROMIS UE-CAT indicate a need for optimization of individual test items to correspond to shoulder function. Until further refinements in the PROMIS UE-CAT instrument are made, it should not replace the ASES instrument in patients undergoing primary RCR.

Prior Anterior Cruciate Ligament Reconstruction Does Not Compromise the Functional Outcomes of Medial Unicompartmental Knee Arthroplasty Although Revision for Progressive Arthritis May Occur Earlier.

BACKGROUND: Anterior cruciate ligament (ACL) deficiency is commonly considered a contraindication for unicompartmental knee arthroplasty (UKA). The purpose of this study is to compare the outcomes of UKA after prior ACL reconstruction (rACL cohort) to UKA with an intact native ACL (nACL cohort). METHODS: Forty-five patients from 3 institutions who underwent medial UKA after prior rACL were matched by age, gender, preoperative function scores, and body mass index to 90 patients who underwent UKA with an intact nACL. Primary outcomes were Knee Injury and Osteoarthritis Outcome Score for Joint Replacement, Oxford Knee Scores, Knee Society Functional Scores, and Kellgren-Lawrence scores in the unresurfaced, lateral tibiofemoral compartment. Secondary outcomes were postoperative complications and the need for revision to TKA. RESULTS: At a mean of 3.6 years, all PROMs improved significantly with no differences identified between groups. The incidence of revision TKA was similar between cohorts (P = 1.00); however, the mean time to revision for progressive osteoarthritis was 4.0 years in the nACL group and 2.2 years in the rACL group. Twenty percent of rACL patients had a postoperative complication compared to 8% in the nACL group. Despite presenting with a similar degree of lateral arthritis, a greater percentage of patients developed Kellgren-Lawrence scores of ≥3 in the rACL cohort (9%) than in the nACL cohort (0%). CONCLUSION: A previously reconstructed ACL does not appear to compromise the short-term functional outcomes of UKA; however, there is a higher rate of minor complications and progression of lateral compartment arthritis, which should be considered with patients in the shared decision process.

Forearm Flexor Tendon Injury in Adolescent Athletes: Risk Factors, Treatment, and Prevention.

ABSTRACT: Injury to the flexor pronator mass is a common condition that is especially prevalent in overhead throwing athletes. The increasing incidence of these injuries has promoted considerable efforts in research to better understand the pathology, risk factors, and potential mechanisms to prevent injury in these athletes. While there are numerous intrinsic and extrinsic factors associated with injury, a common theme involves chronic overuse and microtrauma with inadequate resting intervals between performances. The purpose of this review is to discuss medial elbow injuries in young athletes with a particular focus on the flexor pronator mass.

Establishing and comparing reference preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) scores in patients undergoing shoulder surgery.

BACKGROUND: The Patient-Reported Outcomes Measurement Information System (PROMIS) has become increasingly popular among orthopedic surgeons treating shoulder pathology. Despite this, there have been few studies that have described and compared preoperative reference scores for specific shoulder surgical procedures. The primary purpose of this study was to establish and compare baseline preoperative PROMIS scores for 3 common types of shoulder surgery: rotator cuff repair (RCR), total shoulder arthroplasty (TSA), and labral repair (LR). The secondary goal was to stratify these operative groups by diagnosis and compare preoperative PROMIS scores. METHODS: In this cross-sectional study, adult and pediatric patients who underwent surgery for either RCR, TSA, or LR were included. PROMIS-Upper Extremity (UE), PROMIS-Pain Interference (PI), and PROMIS-Depression (D) scores that were collected at each patient's preoperative visit were reviewed. Continuous and categorical variables were compared between operative groups using analysis of variance and χ2 or Fisher exact tests, respectively. Multivariable general linear models were used to identify significant independent predictors of PROMIS scores when controlling for age, sex, and body mass index. RESULTS: A total of 413 patients were included in the study: 272 in the RCR group, 84 in the TSA group, and 57 in the LR group. The average PROMIS-UE score was 39.8 in the LR group vs. 29.9 in the RCR group (P < .001) and 29.6 in the TSA group (P < .001). There was no difference between the mean RCR and TSA PROMIS-UE scores (P = .93). The average PROMIS-PI score was 56.6 in the LR group vs. 62.8 in the RCR group (P < .001) and 63.9 in the TSA group (P < .001). There was no difference between RCR and TSA PROMIS-PI scores (P = .09). The average PROMIS-D score was 43.5 in the LR group vs. 47.7 in the RCR group (P = .004) and 50.3 in the TSA group (P < .001). The TSA group had a higher mean PROMIS-D score than the RCR group (P = .03). For PROMIS-UE scores, age and body mass index were not found to be significant independent predictors (P = .98 and P = .88, respectively). For PROMIS-PI scores, age, body mass index, and sex were not found to be significant independent predictors (P = .31, P = .81, and P = .48, respectively). CONCLUSION: Patients undergoing shoulder LR had higher preoperative function scores and lower pain interference and depression scores than those undergoing TSA and RCR. These baseline PROMIS scores should be taken into consideration when tracking a patient's outcomes after surgery, as a certain score could mean drastically different functional and pain outcomes depending on the underlying pathology.

Social media use by shoulder and elbow surgeons increases the number of ratings on physician review websites.

BACKGROUND: The use of physician review websites by patients is increasingly frequent. One potential way for shoulder and elbow surgeons to enhance their online reputation and attract patients is via social media, yet its impact is unknown. This study sought to analyze the effect of social media use on the number of online ratings and overall rating of shoulder and elbow surgeons. We secondarily studied variables affecting social media use. METHODS: The American Shoulder and Elbow Surgeons directory was probed to identify practicing surgeons. Surgeon evaluation data, including ratings, comments, and reviews, were compiled from 3 physician review websites (Google, Healthgrades, and Vitals). Google was queried to assess for a professional Facebook, Twitter, or Instagram account, as well as obtain information on surgeon training, practice location, and other demographic variables. RESULTS: A total of 646 surgeons met the inclusion criteria (93.8% male and 6.2% female surgeons). Overall, 37% had a professional social media account (Facebook, 23.1%; Twitter, 24.1%; and Instagram, 9.4%). Linear regression analysis showed that Facebook use correlated with an average increase of 48.6 in the number of ratings. No social media platform correlated with physician rating. The surgeons more likely to use social media were those who graduated residency in 2000 or later (40.8% vs. 29.2%), those who practiced in cities with higher populations (mean, 1188.9 vs. 708.4 [per 1000]), and those with more surgeons practicing in the same city (mean, 7.0 vs. 5.0). CONCLUSION: The majority of shoulder and elbow surgeons do not have a professional social media account. Those using this platform are younger and located in more populous cities with more competition. Having a professional social media profile was not correlated with ratings, but there was a positive association with the number of online ratings, and Facebook had the strongest association. Surgeon ratings are overwhelmingly positive with minimal variability; therefore, a high number of ratings confirms a surgeon's exceptional reputation. The residency graduation year, city population, and number of nearby surgeons affected ratings, although the absolute differences were minimal. For shoulder and elbow surgeons, a professional social media account correlates with an increase in the number of online physician ratings. Recent graduates practicing in competitive locations may feel increased pressure to leverage this in an attempt to build their practices.

Defining Meaningful Functional Improvement on the Visual Analog Scale for Satisfaction at 2 Years After Hip Arthroscopy for Femoroacetabular Impingement Syndrome.

PURPOSE: To (1) define Substantial Clinical Benefit (SCB), Patient Acceptable Symptomatic State (PASS), and Minimal Clinically Important Difference (MCID) for the visual analog scale (VAS) Satisfaction in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS), and (2) identify preoperative predictors of achieving each outcome end-point. METHODS: Data from consecutive patients who underwent primary hip arthroscopy between November 2014 and January 2017 were prospectively collected and retrospectively analyzed. Inclusion criteria consisted of patients with clinical and radiographic diagnosis of FAIS, who failed nonoperative treatment, underwent primary hip arthroscopy to address the FAIS, and had at minimum 2-year follow-up. Baseline data and postoperative patient-reported outcome scores were recorded at 2 years postoperatively. To quantify clinical significance of outcome achievement on the VAS)Satisfaction, we calculated MCID, PASS, and SCB for this outcome measure. A multivariate logistic regression analysis was used to identify preoperative predictors of achieving SCB, PASS, and MCID satisfaction. RESULTS: A total of 335 patients were included in the final analysis, with an average age and body mass index (BMI) of 32.8 (standard deviation ± 12.4) years and 25.2 (standard deviation ± 5.3), respectively, and the majority being female (69.3%). The values on the VAS satisfaction were identified to represent MCID, PASS, and SCB, respectively: 52.8, 80.9, and 89.7. The rates of achieving clinically significant improvement on the VAS Satisfaction was 85.6%, 68.1%, and 56.9% for MCID, PASS, and SCB, respectively. A larger preoperative alpha angle was predictive for achieving SCB (odds ratio [OR], 1.076; P = .046), whereas lower BMI (OR, 0.955; P = .047) and larger preoperative alpha angle (OR, 1.12; P = .025) were predictors for achieving PASS. CONCLUSIONS: This study identified threshold VAS satisfaction scores of 52.8, 80.9, and 89.7 for achieving MCID, SCB, and PASS, respectively, at 2-year follow-up following hip arthroscopy for FAIS. Furthermore, preoperative variables including larger preoperative alpha angles and lower BMI are predictors of achieving superior clinical satisfaction. LEVEL OF EVIDENCE: Level IV, Case Series.

Development and Validation of the Hospital for Special Surgery Anterior Cruciate Ligament Postoperative Satisfaction Survey.

PURPOSE: To develop and validate a standardized patient satisfaction measurement tool for adult patients undergoing primary anterior cruciate ligament reconstruction (ACLR). METHODS: A 4-phase iterative process that included item generation and pilot survey development, item reduction, survey readability, and survey validation was used. To develop and validate the Hospital for Special Surgery ACL Satisfaction Survey (HSS ACL-SS), 70 patients were included in the survey development phase and 77 patients were included in the validation phase. The HSS ACL-SS was compared with other currently used ACLR outcome measures including the International Knee Documentation Committee score, Tegner-Lysholm score, Short Form 12 (SF-12) Mental Component Score, and SF-12 Physical Component Score. Test-retest reliability, internal consistency, convergent and discriminant validity, and floor and ceiling effects were assessed. RESULTS: The HSS ACL-SS consists of 10 items identified by patients as being important for satisfaction after ACLR. In the validation phase, the mean score on the HSS ACL-SS (of 50) among all patients was 37.9 ± 9.9 (range, 10-50). Statistically significant positive correlations were seen between the HSS ACL-SS score and the International Knee Documentation Committee score (r = 0.351, P = .002) and Tegner-Lysholm score (r = 0.333, P = .003). No statistically significant correlation was found between the satisfaction score and the SF-12 Mental or Physical Component Score. The lowest possible score (10 of 50 points) was achieved in 1 patient (1.3%) and the highest possible score (50 of 50 points) was achieved in 7 patients (9.1%), indicating no significant floor or ceiling effects of the instrument. Internal consistency for all 10 items was strong (Cronbach α, 0.995). The mean intraclass correlation coefficient between test and retest responses was 0.701, indicating moderate agreement. CONCLUSIONS: The HSS ACL-SS is a validated and reliable patient-derived satisfaction measure with excellent psychometric properties for active adults undergoing ACLR. The results of this study show that the HSS ACL-SS may be a useful tool to measure postoperative patient satisfaction. LEVEL OF EVIDENCE: Level II, development of diagnostic or monitoring criteria in consecutive patients.

Epidemiology of multiligament knee reconstruction.

BACKGROUND: The multiple-ligament-injured knee represents a special challenge, being an uncommon injury that is both severe and complicated to treat. Many studies have evaluated patients treated for this injury, but most are limited in their scope. The evaluation of this injury and its treatment using an administrative database might provide a different perspective. QUESTIONS/PURPOSES: Using a large administrative database, we determined (1) the number of multiligament knee reconstructions in New York State, (2) the rate of 90-day hospital readmission, and (3) the frequency of subsequent knee surgery. We examined the rates of these outcomes as a function of diagnosis, admission type, discharge status, comorbidity burden, and patient demographic factors. METHODS: We used the New York Department of Health Statewide Planning and Research Cooperative System (SPARCS), a database with information on patient characteristics, diagnoses, and treatments, to identify patients who underwent a multiligament procedure in a nonfederal facility from 1997 to 2005 using ICD-9-CM and Current Procedural Terminology codes. SPARCS collects data from all nonfederal acute care facilities, with an estimated reporting completeness of almost 99% for the years in this study. We evaluated data on patient age, sex, admission type, discharge status, and comorbidity burden (using Elixhauser comorbidities) and developed a multivariable logistic regression model to assess the influence of confounding variables. RESULTS: We identified 1032 patients in this database who underwent multiligament knee reconstruction in New York State from 1997 to 2005. The frequency of readmission within 90 days was 4.8% (n = 49). Readmission was more likely for patients who underwent inpatient multiligament reconstruction (odds ratio [OR] = 2.3; 95% CI: 1.2-4.4; p = 0.014), had a diagnosis of dislocation (OR = 2.2; 95% CI: 1.2-3.9; p = 0.011), or had various Elixhauser comorbidities, including chronic lung disease (OR = 6.4; 95% CI: 1.5-27.2; p = 0.013), fluid and electrolyte disorders (OR = 19.7; 95% CI: 2.5-155.7; p = 0.005), and anemia deficiency (OR = 5.6; 95% CI: 1.05-29.4; p = 0.044). Two hundred eighty-seven patients (28%) underwent subsequent knee surgery between their index procedure and 2006. Subsequent surgery was more likely for patients who underwent inpatient multiligament reconstruction (OR = 1.4; 95% CI: 1.1-1.9; p = 0.011) or were readmitted within 90 days of the index surgery (OR = 4.2; 95% CI: 2.3-7.6; p < 0.001). CONCLUSIONS: Our findings have the potential to aid clinicians in identifying their patients with multiligament reconstruction at highest risk for 90-day readmission and subsequent knee surgery. Future research, particularly large prospective studies evaluating surgical approaches and timing, will be critical in advancing the treatment of multiligament knee injuries.

When Do Patients Achieve PROMIS Milestones After Rotator Cuff Repair?

Background: Given the variability of the questions asked, the Patient-Reported Outcomes Measurement Information System (PROMIS) upper extremity (UE) computer adaptive test (CAT) Version 2.0 item bank aids in the evaluation of rotator cuff repair (RCR) rehabilitation by determining when recovery milestones are possible based on the quality of patient responses at certain time points. Purpose: To assess the time point at which patients with RCR were able to achieve specific functional milestones, determined as positive responses to the 5 most frequently asked items on the PROMIS UE CAT Version 2.0. Study Design: Case series; Level of evidence, 4. Methods: The postoperative PROMIS UE CAT Version 2.0 scores of patients who underwent RCR between February 16, 2017, and July 30, 2019, were reviewed with respect to individual PROMIS item, response, and timing of response. A functional milestone was considered achieved if the patient response was "without any difficulty" or "with a little difficulty" to any of the 5 most frequently asked PROMIS items. The percentage of patients in each monthlong postoperative interval who answered with either response was recorded. The logit generalized estimating equations method was used to analyze the association between milestone achievement for each PROMIS item and predictor variables (age, sex, body mass index, smoking status, race, ethnicity, and employment status). Results: A total of 1131 responses from 371 patients were included. The majority of patients attained milestone achievement on 4 of the 5 most frequently asked PROMIS items at time points ranging from 1 to 5 months postoperatively: "Are you able to carry a shopping bag or briefcase?" (by 1 month), "Are you able to put on and take off a coat or jacket?" (by 3 months), "Are you able to pour liquid from a bottle into a glass?" (by 3 months), and "Are you able to carry a heavy object (over 10 pounds/5 kg)?" (by 5 months). For the item "Are you able to put on a shirt or blouse?", the majority of patients did not achieve the milestone by 1 year. Conclusion: These findings support the application of PROMIS UE CAT Version 2.0 milestone achievement in the shared decision-making process and postoperative monitoring, as patients can use this information to determine when they can return to certain activities and providers can apply these standards to identify patients needing additional clinical support.

Management of Glenoid Bone Loss in Primary Reverse Total Shoulder Arthroplasty.

PURPOSE OF REVIEW: Glenoid bone loss presents distinct challenges in reverse total shoulder arthroplasty (rTSA) which, if unaddressed, can cause complications including poor outcomes and early implant failure. The purpose of this review is to discuss the etiology, evaluation, and management strategies of glenoid bone loss in primary rTSA. RECENT FINDINGS: Three-dimensional computed tomography (3D CT) imaging and preoperative planning software have revolutionized the understanding of complex glenoid deformity and wear patterns from bone loss. With this knowledge, a detailed preoperative plan can be created and implemented for a more optimal management strategy. When appropriately indicated, deformity correction techniques with biologic or metal augmentation are successful in addressing the glenoid bone deficiency, creating optimal implant position, and thus providing stable baseplate fixation and improving outcomes. Thorough evaluation and characterization of the degree of glenoid deformity with 3D CT imaging is necessary prior to treatment with rTSA. Eccentric reaming, bone grafting, and augmented glenoid components have shown promising results in correcting glenoid deformity due to bone loss, but long-term outcomes are currently unknown.

Management of Periprosthetic Bone Cysts After Total Ankle Arthroplasty.

Modern improvements in total ankle arthroplasty (TAA) have increased the performance of this procedure for treatment of end-stage ankle arthritis. A common finding after TAA is the formation of periprosthetic bone cysts, which can be clinically silent or result in TAA failure. The exact cause of periprosthetic bones cysts has not been established, but major theories are related to osteolysis secondary to implant wear, micromotion, and stress shielding. Treatment can be nonoperative with clinical observation for small, asymptomatic cysts. Large, progressive, and symptomatic cysts often merit surgical treatment with debridement and grafting, revision TAA, or salvage arthrodesis.

Patellar fracture among elite-level European soccer players: 4-year case-control cohort analysis of return to play, re-injury, and player performance.

OBJECTIVES: There is a paucity of literature investigating the relationship between patellar fracture and player performance of professional soccer players following return to play (RTP). Our goal is to determine the rate of RTP, time to RTP, and effect on player performance following patellar fracture. METHODS: Twenty-one elite-level European professional soccer players who sustained a patellar fracture between 1999 and 2018 were identified via a publicly accessible database. Athletes with patellar fracture were matched to controls by age, height, years played in the league, season of injury, and position. Change in performance metrics between one season prior to injury and the following four seasons after injury were compared. RESULTS: Players with patellar fracture were absent for a mean 207.95 ± 135.55 days and 16.81 ± 31.79 games. Fifteen (71%) players returned to play after injury with 67% returning within 1 season after injury. Injured players did not demonstrate significant change in performance metrics at any of the follow-up timepoints compared to control. Subgroup analysis showed that attackers recorded approximately 1200 fewer minutes played per season than pre-injury levels 2 seasons following injury, significantly fewer (p < 0.05) than the control cohort recording similar minutes per season throughout the study period. Midfielders and defenders demonstrated similar fluctuations in performance to the control cohort for both field time and performance metrics (p > 0.05). CONCLUSION: Seventy-one percent of players RTP after patellar fracture with an associated absence of 7 months and 17 missed games. Overall, injured players did not demonstrate a significant decline in performance as demonstrated by games played, total minutes played per season, minutes per game, assists, and goals 1 season after injury. Attackers played fewer minutes during the season of and 2 seasons after the initial injury.

Mid-Flexion Instability After Total Knee Arthroplasty: Diagnosis, Implant Design, and Outcomes.

Mid-flexion instability (MFI) in total knee arthroplasty refers to a distinct clinical entity where the knee is stable at full extension and 90° of flexion, but unstable somewhere between these 2 points. The presentation of MFI is often vague, and studies defining objective clinical or intraoperative measurements are limited. In this review, we aim to properly define the condition, describe diagnostic criteria and risk factors contributing to MFI, review current implant design, and present outcomes of revision surgery performed for MFI.

Internet search analytics for shoulder arthroplasty: what questions are patients asking?

BACKGROUND: Common questions about shoulder arthroplasty (SA) searched online by patients and the quality of this content are unknown. The purpose of this study is to uncover questions SA patients search online and determine types and quality of webpages encountered. METHODS: The "People also ask" section of Google Search was queried to return 900 questions and associated webpages for general, anatomic, and reverse SA. Questions and webpages were categorized using the Rothwell classification of questions and assessed for quality using the Journal of the American Medical Association (JAMA) benchmark criteria. RESULTS: According to Rothwell classification, the composition of questions was fact (54.0%), value (24.7%), and policy (21.3%). The most common webpage categories were medical practice (24.6%), academic (23.2%), and medical information sites (14.4%). Journal articles represented 8.9% of results. The average JAMA score for all webpages was 1.69. Journals had the highest average JAMA score (3.91), while medical practice sites had the lowest (0.89). The most common question was, "How long does it take to recover from shoulder replacement?" CONCLUSIONS: The most common questions SA patients ask online involve specific postoperative activities and the timeline of recovery. Most information is from low-quality, non-peer-reviewed websites, highlighting the need for improvement in online resources. By understanding the questions patients are asking online, surgeons can tailor preoperative education to common patient concerns and improve postoperative outcomes.
