Use of Area Deprivation Index to Predict Minimal Clinically Important Difference for Patient Reported Outcomes Measurement Information System After Arthroscopic Rotator Cuff Repair.

BACKGROUND: Socioeconomic disparities correlate with worse outcomes after arthroscopic rotator cuff repair. However, use of a surrogate to describe socioeconomic disadvantage has been a challenge. The Area Deprivation Index (ADI) is a tool that encompasses 17 socioeconomic variables into a single metric based on census location. HYPOTHESIS: Higher ADI would result in a worse minimal clinically important difference (MCID) for the Patient Reported Outcomes Measurement Information System (PROMIS) and have less improvement in range of motion (ROM) following arthroscopic rotator cuff repair (ARCR). STUDY DESIGN: Cohort study; Level of evidence, 3. METHOD: A retrospective review was performed for patients who underwent arthroscopic rotator cuff repair. Patients in the most socioeconomically disadvantaged quartile (ADIHigh) were compared with the least disadvantaged quartile (ADILow) in the ability to reach MCID. Demographic and surgical features were assessed for attainment of MCID. RESULTS: In total 1382 patients were identified who underwent ARCR, of which a total of 306 patients met final inclusion criteria. A higher percentage of patients within the ADIHigh cohort identified as "Black" or "other" race and had government-issued insurance compared with the ADILow cohort (P < .05). The ADIHigh cohort had significantly worse postoperative forward flexion compared with the ADILow cohort (145.0°± 32.5° vs 156.3°± 23.4°; P = .001) despite starting with comparable preoperative ROM (P = .17). Logistic regression showed that ADI was the only variable significant for predicting achievement of MCID for all 3 PROMIS domains, with the ADIHigh cohort having significantly worse odds of achieving MCID Physical Function (odds ratio [OR], 0.31; P = .001), Pain Interference (OR, 0.21; P = .001), and Depression (OR, 0.28; P = .001). Meanwhile, age, sex, body mass index, and smoking history were nonsignificant. Moreover, "other" for race and Medicare insurance were significant for achievement of MCID Depression but not Physical Function or Pain Interference. Finally, ADI was the main feature for predictive logistic regression modeling. CONCLUSION: ADI served as the only significant predictor for achieving MCID for all 3 PROMIS domains after arthroscopic rotator cuff repair. Patients who face high levels of socioeconomic disadvantage have lower rates of achieving MCID. In addition, patients with greater neighborhood disadvantage demonstrated significantly worse improvement in active forward flexion. Further investigation is required to understand the role of ADI on physical therapy compliance and to identify the barriers that prevent equitable postoperative care.

Effect of Insurance Reimbursement Status on Pre- and Postoperative Patient-Reported Outcomes Measurement Information System (PROMIS) Scores After Arthroscopic Rotator Cuff Repair.

BACKGROUND: Previous studies reported inferior patient-reported outcomes (PROs) after arthroscopic rotator cuff repair for patients receiving workers' compensation (WC) relative to patients with commercial insurance. The extent to which alternative insurance reimbursement, including Medicaid and Medicare, influences outcomes after arthroscopic rotator cuff repair remains understudied. HYPOTHESIS: Compared with patients with commercial insurance reimbursement, patients with WC or government-issued reimbursement would report lower pre- and postoperative Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) scores, report higher pre- and postoperative PROMIS Depression (D) and Pain Interference (PI) scores, and experience smaller levels of improvement in all PROMIS domains with surgical intervention. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Demographic and surgical data were extracted from the medical record, and PROMIS domains were prospectively collected. Patients were divided into cohorts based on insurance reimbursement status. Differences between insurance-based cohorts for baseline variables, pre- and postoperative PROMIS scores, and change from baseline to final follow-up (delta) for PROMIS scores were evaluated using Kruskal-Wallis or chi-square tests. Mixed-effects linear regression models were performed to assess the influence of insurance while controlling for other variables. Survival analysis was performed to determine time to achieve minimal clinically important difference (MCID) for each PROMIS domain per cohort. RESULTS: 1252 patients underwent arthroscopic rotator cuff repair, met inclusion criteria, and completed PROMIS questionnaires. Statistically significant differences were noted in demographic variables including age (P < .001), sex (P < .001), ethnicity (P < .001), and body mass index (P < .001) between insurance-based cohorts. Unadjusted analysis revealed significantly higher PF scores and lower PI and D scores for the group with commercial insurance relative to those with Medicare, Medicaid, and WC at 6- and 12-month follow-up (P < .01 all comparisons), except for the Medicare versus commercial subcohort analysis for PI at 6 months (P = .28). These differences persisted for the Medicare, Medicaid, and WC groups (P < .03 all comparisons) after adjustment for confounding variables in linear regression. CONCLUSIONS: The baseline characteristics of patients undergoing arthroscopic rotator cuff repair differed based on insurance reimbursement. Patients with commercial insurance reported improved physical function, decreased pain interference, and improved mood (less depression) relative to patients with government-issued and WC insurance, with maximum improvement 6 to 12 months postoperatively. There were few significant differences between insurance groups in change of PROMIS scores from preoperative to postoperative intervals, indicating that differences in the baseline demographic and surgical characteristics of these groups accounted for differences in response to surgery.

Clinically Depressed Patients Having Anterior Cruciate Ligament Reconstruction Show Improved but Inferior Rate of Achieving Minimum Clinically Important Difference for Patient-Reported Outcomes Measurement Information System Compared With Situationally Depressed or Nondepressed Patients.

PURPOSE: To determine whether the preoperative diagnosis of depression predicted worse postoperative outcomes, including physical therapy (PT) compliance, return-to-sport, and patient-reported outcomes using the Patient-Reported Outcomes Measurement Information System (PROMIS) after anterior cruciate ligament (ACL) reconstruction. METHODS: A multisurgeon series of consecutive patients who had undergone ACL reconstruction with minimum 2-year follow-up were included. Chart review was conducted to determine depression diagnosis status, demographic data, rehabilitation PT compliance, return to sports, and patient-reported outcome data using PROMIS. Patients who met the PROMIS threshold for mild depression but did not carry a clinical diagnosis of depression were classified as "situationally depressed." RESULTS: Ninety-five of 115 consecutive patients (81%) met inclusion criteria with an average follow-up of 34 ± 1.9 months. Fourteen patients (15%) had a preoperative diagnosis of depression, whereas 21 (22%) were considered situationally depressed. Clinically depressed patients had a greater rate of PT noncompliance (33.2% ± 17.6% vs 21.9% ± 12.6%; P = .02) and a lower postoperative PROMIS Physical Function (50.8 ± 7.7 vs 57.8 ± 11.0; P = .03 compared with patients without depression. Situationally depressed patients had lower preoperative physical function (35.4 vs 42.5; P = .04) with no differences in postoperative outcomes scores compared to the non-depressed cohort.19/21 (90.5%) of situationally depressed patients had postoperative resolution of their depressive symptoms. CONCLUSIONS: Situationally depressed patients without a clinical diagnosis of depression can expect significant improvements in both pain and function, as well as a resolution of their depressed mood based on PROMIS scores as they progress through recovery after ACL reconstruction. Clinically depressed patients also experience significant improvements; however, their rate of achieving the minimum clinically important difference for PROMIS outcomes may be less than their nondepressed or situationally depressed counterparts. LEVEL OF EVIDENCE: III, prognostic comparative trial.

Preoperative PROMIS Scores Predict Postoperative Outcomes After Primary ACL Reconstruction.

BACKGROUND: PROMIS (Patient-Reported Outcomes Measurement Information System) scores in patients undergoing anterior cruciate ligament (ACL) reconstruction have not been fully described in the literature to date. The ability of preoperative patient-reported outcome scores to directly predict postoperative outcomes in patients who undergo primary ACL reconstruction is unknown. HYPOTHESIS: Postoperative PROMIS physical function (PF), pain interference (PI), and depression (D) scores in patients who undergo ACL reconstruction will show improvement when compared with preoperative scores. Additionally, preoperative PROMIS PF, PI, and D scores will predict which patients will not achieve a minimal clinically important difference (MCID) postoperatively. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A total of 233 patients who underwent primary ACL reconstruction between 2015 and 2016 and had completed PROMIS measures both preoperatively (within 60 days of surgery) and postoperatively (100-240 days after surgery) were included in this study. PROMIS PF, PI, and D scores were compared. Accuracy analyses were performed to determine whether preoperative PROMIS scores from each domain could predict postoperative achievement of MCID in the same domain. Cutoff scores were then calculated. RESULTS: PROMIS PF, PI, and D scores all showed a significant improvement after ACL reconstruction (all P < .001). Preoperative scores from all 3 PROMIS domains showed a strong ability to predict clinically meaningful improvement, as defined by MCID, with areas under the receiver operating characteristic curve from 0.72 to 0.84. Optimal cutoffs for preoperative PROMIS scores showed that patients with a PF score of <42.5, PI score of >56.2, or D score of >44.8 were more likely to achieve MCID. CONCLUSION: PROMIS PF, PI, and D scores improved significantly in patients who underwent primary ACL reconstruction. Preoperative PROMIS PF, PI, and D scores were highly predictive of outcome in the early postoperative period. The reported cutoff scores showed high probability in predicting which patients would and would not achieve a clinically meaningful improvement.

Assessing Diagnostic Arthroscopy Performance in the Operating Room Using the Arthroscopic Surgery Skill Evaluation Tool (ASSET).

PURPOSE: To determine the validity and reliability of using the Arthroscopic Surgery Skill Evaluation Tool (ASSET) to assess arthroscopic skill in the operating room. METHODS: Eight orthopaedic residents, 1 sports medicine fellow, and 3 sports medicine faculty members recorded the diagnostic portion of 3 shoulder and 3 knee procedures in the operating room. Two blinded raters used the ASSET to assess each recorded procedure video. Criterion for a passing score on a procedure was attaining a 3 or greater in all 8 domains assessed. RESULTS: In total 70 videos (36 shoulder, 34 knee) were evaluated by each rater. The attending/fellow group was assigned significantly higher mean ASSET scores compared with resident groups for both procedures (P = .01). The attending/fellow group also had the highest passing percentage (95.8%). Raters were in agreement for total ASSET scores assigned to both diagnostic arthroscopy of the shoulder (intraclass correlation coefficient [ICC] = 0.84) and knee (ICC = 0.81). Agreement on individual ASSET domains was moderate (ICC = 0.61 to 0.80) for all domains except safety and difficulty of procedure. Raters concurred on the pass-fail evaluation in 62 of 70 (88.6%) of procedures evaluated. CONCLUSIONS: Using the ASSET to assess surgical skills in the operating room is feasible, reliable, and valid. CLINICAL RELEVANCE: When combined with previously published results using the ASSET, the ASSET may provide a validated and reliable method for evaluating arthroscopic surgical skills in the surgical simulation lab and operating room.

Unilateral meniscomeniscal ligament.

Four normal variants of meniscomeniscal ligaments have been previously reported in the anatomy, arthroscopy, and radiology literature. The anterior and posterior transverse meniscal ligaments are the 2 most commonly observed, with a reported frequency of 58% and 1% to 4%, respectively. The last 2 variants include the medial and lateral oblique meniscomeniscal ligaments and account for a combined frequency of 1% to 4%.This article describes 2 patients with unilateral meniscomeniscal ligaments observed on magnetic resonance imaging. One patient had a unilateral lateral meniscomeniscal ligament extending from the anterior horn of the lateral meniscus to the posterior horn of the lateral meniscus and underwent conservative management. The second patient had a unilateral medial meniscomeniscal ligament with a concomitant medial meniscus tear and underwent arthroscopic intervention. The ligament was stable intraoperatively and, therefore, was not resected. Both patients had resolution of their symptoms.These 2 variants are additions to the previously described 4 normal intermeniscal ligament variants. The functions of the 2 new variants described in this article are poorly understood but are thought to involve meniscal stability. Accurate descriptions of normal variants can lead to the proper management of anomalous rare structures and prevent false imaging interpretations because these structures can closely mimic a double posterior cruciate ligament sign. Furthermore, an understanding of the various normal variants of intermeniscal ligaments can prevent unnecessary surgery that could result in further iatrogenic meniscus injury.

Reconstruction of the anterior cruciate ligament: meta-analysis of patellar tendon versus hamstring tendon autograft.

PURPOSE: No graft tissue has consistently shown superiority over others for reconstruction of the anterior cruciate ligament (ACL). Bone-patellar tendon-bone (BPTB) and doubled hamstring tendon (semitendinosus and gracilis) (HT) are the most commonly used autologous grafts. We performed a meta-analysis to compare the effectiveness of ACL reconstruction using either BPTB or HT grafts. TYPE OF STUDY: Systematic review and meta-analysis. METHODS: We searched the MEDLINE database (1966 to April 2003) for English-language randomized or prospective studies comparing BPTB and 3- or 4-strand HT grafts used for ACL reconstruction. For inclusion, studies were required to follow identical rehabilitation protocols within each study, and provide subjective or objective outcome data after a minimum average 2-year follow-up. Comparison data between BPTB and HT for each identified outcome measure were combined using a random-effects model meta-analysis. RESULTS: Eleven reports fulfilled the criteria for inclusion. Outcomes favoring BPTB were found in the following outcome measures: normal Lachman examination (relative risk [RR], 0.91; 95% confidence interval [CI], 0.83-0.99; P = .025), normal pivot-shift (RR, 0.94; 95% CI, 0.88-1.0; P = .067), KT-1000 manual-maximum side-to-side difference of < or = 3 mm (RR, 0.75; 95% CI, 0.55-1.01; P = .057), and fewer reconstructions resulting in flexion loss > 5 degrees (RR, 1.41; 95% CI, 1.01-1.96; P = .04). Intermediate level laxity was more common with the HT graft, as shown by higher rates of abnormal Lachman > 0 (RR, 1.22; 95% CI, 0.99-1.5; P = .06), pivot-shift > 0 (RR, 1.3; 95% CI, 0.96-1.75; P = .09), and KT-1000 manual-maximum side-to-side differences > 3 mm (RR, 1.64; 95% CI, 1.13-2.39; P = .01). Outcome measures that favored HT were absence of patellofemoral crepitance (RR, 1.08; 95% CI, 1.01-1.15; P = .03), fewer results with extension loss > 5 degrees (RR, 0.56; 95% CI, 0.3-1.03; P = .06), and kneeling pain. The incidence of instability, as defined by Lachman grade 2, pivot-shift grade 2, or KT-1000 manual-maximum side-to-side difference > 5 mm, was not significantly different between the 2 grafts. All other outcome measures were not significantly different. CONCLUSIONS: The data presented in this meta-analysis show that the incidence of instability is not significantly different between the BPTB and HT grafts. However, BPTB was more likely to result in reconstructions with normal Lachman, normal pivot-shift, KT-1000 manual-maximum side-to-side difference < 3 mm, and fewer results with significant flexion loss. In contrast, HT grafts had a reduced incidence of patellofemoral crepitance, kneeling pain, and extension loss. The choice of graft by the patient and surgeon must be individualized, and the results of this meta-analysis can aid in the decision by clarifying the risks and benefits of each surgical approach.
