The Statistical Fragility of Patellar Resurfacing in Total Knee Arthroplasty: A Systematic Review of Randomized Controlled Trials. J Arthroplasty 2024:S0883-5403(24)00944-6. [PMID: 39321972 DOI: 10.1016/j.arth.2024.09.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 09/03/2024] [Accepted: 09/10/2024] [Indexed: 09/27/2024] Open
Abstract
INTRODUCTION Randomized controlled trials (RCTs) evaluating patellar resurfacing in total knee arthroplasty (TKA) have conflicting findings, with some reporting its efficacy and others demonstrating no clinical significance. The fragility index (FI), reverse fragility index (rFI), and fragility quotient (FQ) evaluated statistical fragility of outcomes in RCTs evaluating patellar resurfacing in TKA. METHODS The PubMed, Embase, and MEDLINE databases were systematically searched for RCTs (January 1, 2000, to August 1, 2023) assessing patellar resurfacing in TKA. Of 226 RCTs screened, 19 studies were included for analysis. We calculated FI and rFI, which represent the number of outcome event reversals required to alter statistical significance for significant and non-significant outcomes, respectively. The outcome categories of interest included anterior knee pain, complications/ adverse events, crepitus, reoperation, patient satisfaction, and clinical improvement. The FQ was determined by dividing the FI by the study sample size. RESULTS Across 46 outcomes, the median FI was 5 (Interquartile Range (IQR) 3 to 8) with a median FQ of 0.041 (IQR 0.025 to 0.063). There were nine outcomes that were statistically significant, with a median FI of 3 (IQR 2 to 8) and a FQ of 0.011 (IQR 0.0044 to 0.039). There were 37 outcomes that were non-significant, with a median rFI of 5 (IQR 4 to 7) and FQ of 0.043 (IQR 0.031 to 0.062). Notably, in 47.8% of all outcomes, the number of patients lost-to-follow-up was greater than the outcome's respective FI or rFI. Outcomes regarding patient satisfaction (FI 4.5) and anterior knee pain (FI 5) were most fragile. CONCLUSION The outcomes of interest regarding patellar resurfacing from RCTs are statistically fragile, particularly significant outcomes and patient satisfaction outcomes. Data surrounding patellar resurfacing remains inconclusive, and combining P-values with FI/FQ metrics may aid in interpreting patellar resurfacing findings. Future studies may mitigate fragility by obtaining higher follow-up rates and sample sizes.

A threshold of lower preoperative mental health is associated with decreased achievement of comfort and capability benchmarks following rotator cuff repair: a retrospective cohort study. J Shoulder Elbow Surg 2024; 33:e403-e414. [PMID: 38325556 DOI: 10.1016/j.jse.2023.12.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 12/13/2023] [Accepted: 12/17/2023] [Indexed: 02/09/2024]
Abstract
BACKGROUND Preoperative biomedical patient characteristics are known to affect the time to achievement of clinically significant outcomes (CSOs) following arthroscopic rotator cuff repair (RCR). However, less is known about the association between preoperative mental status and the time to achievement of CSOs. We hypothesize that higher preoperative mental status is associated with faster achievement of CSOs following arthroscopic RCR. METHODS Patient-reported outcome measures (PROMs) were collected preoperatively and at postoperative intervals up to 2 years. PROMs included pain visual analog scale (VAS), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), Single Assessment Numeric Evaluation (SANE), and Veterans RAND 12-Item Health Survey (VR-12) scores. Threshold values for CSOs were obtained from previous literature. Mean time to achievement of CSOs was calculated using a Kaplan-Meier analysis. A Cox proportional hazards regression analysis was performed to identify preoperative variables associated with earlier achievement of CSOs. RESULTS Sixty-nine patients with an average age of 59 ± 8 years were included. Patients with higher preoperative mental status, as measured by VR-12 mental component summary (MCS), experienced significantly earlier substantial pain improvement postoperatively (P = .0471). Patients with higher preoperative mental status also achieved CSOs for physical health at earlier time points (P = .0187). Preoperative VR-12 MCS scores ≥ 40 were associated with earlier achievement of CSOs for pain (P = .0005) and physical health (P = .0015). Ninety-eight percent of patients with preoperative MCS scores ≥40 achieved acceptable pain relief at 4.5 months vs. 56% of all other patients at 12.3 months (P = .0001). Patients with preoperative MCS scores ≥40 experienced significantly faster improvement in physical health compared to patients with preoperative MCS scores <40 (P = .0006). CONCLUSIONS Higher preoperative mental status, especially a preoperative MCS score ≥40, is associated with significantly faster improvement in pain and physical function following arthroscopic RCR. Nearly all patients (98%) with preoperative MCS score ≥40 achieved an acceptable state of pain relief compared with only 56% of patients with preoperative MCS score <40. These findings indicate that a holistic approach with equal consideration of preoperative mental health and rotator cuff pathophysiology is vital to the successful management of rotator cuff tendinopathy.

Abstract
ABSTRACT The Centers for Medicare & Medicaid Services (CMS) has finalized a landmark national policy to standardize and expand the collection and reporting of patient-reported outcome measures (PROMs) following total hip arthroplasty (THA) and total knee arthroplasty (TKA). This policy will be rolled out through phased implementation, beginning with voluntary reporting starting in 2023 and transitioning to mandatory reporting starting in 2025, which will be tied to hospital payment determinations in fiscal year 2028. The overarching goal of this policy is to gather meaningful pre- and postoperative PROM data directly from patients to enhance clinical care, shared decision-making, and quality measurement for these common elective procedures. This national initiative underscores the value of incorporating patient perspectives and priorities into assessments of surgical care quality. For orthopaedic surgeons and hospitals, participating in the initial voluntary reporting period provides an opportunity to integrate PROM collection into clinical workflows and to leverage these data to improve patient care. The achievement of robust PROM response rates and a strong performance on the underlying THA/TKA Patient-Reported Outcome-Based Performance Measure may have increasing relevance as payment models shift toward value-based care. The aim of the present forum was to provide an in-depth review of this new CMS policy and key details regarding required PROM instruments, data-collection time frames, and other specifications that surgical teams should understand as they prepare for implementation. The goal was to equip orthopaedic surgeons with actionable information as they embark on this new era of national PROM collection and reporting.

Patient Acceptable Symptom State Thresholds for IKDC-SKF and KOOS at the 10-Year Follow-up After Anterior Cruciate Ligament Injury: A Study From the Delaware-Oslo ACL Cohort. Orthop J Sports Med 2024; 12:23259671241250025. [PMID: 38827138 PMCID: PMC11143835 DOI: 10.1177/23259671241250025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Accepted: 11/16/2023] [Indexed: 06/04/2024] Open
Abstract
Background Clinicians need thresholds for the Patient Acceptable Symptom State (PASS) and Treatment Failure to interpret group-based patient-reported outcome measures after anterior cruciate ligament (ACL) injury. Validated thresholds that are crucial for accurately discerning patient symptom state and facilitating effective interpretation have not been determined for long-term follow-up after ACL injury. Purpose To calculate and validate thresholds for PASS and Treatment Failure for the International Knee Documentation Committee Subjective Knee Form (IKDC-SKF) and the Knee injury and Osteoarthritis Outcome Score (KOOS) subscales at the 10-year follow-up after ACL injury. Study Design Cohort study; Level of evidence, 3. Methods A total of 163 participants with unilateral ACL injury (treated with reconstruction or rehabilitation alone) from the Delaware-Oslo ACL Cohort were included. Thresholds for PASS were calculated for IKDC-SKF and KOOS subscales using anchor-based predictive modeling and receiver operating characteristic (ROC) analysis. Too few participants had self-reported Treatment Failure to calculate thresholds for that outcome. Nonparametric bootstrapping was used to derive 95% CIs. The criterion validity of the predictive modeling and ROC-derived thresholds were assessed by comparing actual patient-reported PASS outcome with the calculated PASS outcome for each method of calculation and calculating their positive and negative predictive values with respect to the anchor questions. Results A total of 127 (78%) participants reported satisfactory symptom state. Predictive modeling PASS thresholds (95% CIs) were 76.2 points (72.1-79.4 points) for IKDC-SKF, 85.4 points (80.9-89.2 points) for KOOS Pain, 76.5 points (67.8-84.7 points) for KOOS Symptoms, 93.8 points (90.1-96.9 points) for KOOS activities of daily living, 71.6 points (63.4-77.7 points) for KOOS Sports, and 59.0 points (53.7-63.9 points) for KOOS quality of life (QoL). Predictive modeling thresholds classified 81% to 93% of the participants as having satisfactory symptom state, whereas ROC-derived thresholds classified >50% as unsatisfied. The thresholds for IKDC-SKF, KOOS Sports, and KOOS QoL resulted in the most accurate percentages of PASS among all identified thresholds and therefore demonstrate the highest validity. Conclusion Predictive modeling provided valid PASS thresholds for IKDC-SKF and KOOS at the 10-year follow-up after ACL injury. The thresholds for IKDC-SKF, KOOS Sports, and KOOS QoL should be used when determining satisfactory outcomes. ROC-derived thresholds result in substantial misclassification rates of the participants who reported satisfactory symptom state.

Rullán, MD 1 , Nicolas S. Piuzzi, MD 1 , and the Cleveland Clinic Arthroplasty Group†". BACKGROUND Literature-reported minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) thresholds for patient-reported outcome measures demonstrate marked variability. The purpose of this study was to determine the minimal detectable change (MDC), MCID, and PASS thresholds for the Knee injury and Osteoarthritis Outcome Score (KOOS) Pain subdomain, Physical Function Short Form (PS), and Joint Replacement (JR) among patients with osteoarthritis (OA) who underwent primary total knee arthroplasty (TKA). METHODS A prospective cohort of 6,778 patients who underwent primary TKA was analyzed. Overall, 1-year follow-up was completed by 5,316 patients for the KOOS Pain, 5,018 patients for the KOOS PS, and 4,033 patients for the KOOS JR. A total of 5,186 patients had an OA diagnosis; this group had an average age of 67.0 years and was 59.9% female and 80.4% White. Diagnosis-specific MDCs and MCIDs were estimated with use of a distribution-based approach. PASS values were estimated with use of an anchor-based approach, which corresponded to a response to a satisfaction question at 1 year postoperatively. RESULTS The MCID thresholds for the OA group were 7.9 for the KOOS Pain, 8.0 for the KOOS PS, and 6.7 for the KOOS JR. A high percentage of patients achieved the MCID threshold for each outcome measure (KOOS Pain, 95%; KOOS PS, 88%; and KOOS JR, 94%). The MDC 80% to 95% confidence intervals ranged from 9.1 to 14.0 for the KOOS Pain, 9.2 to 14.1 for the KOOS PS, and 7.7 to 11.8 for the KOOS JR. The PASS thresholds for the OA group were 77.7 for the KOOS Pain (achieved by 73% of patients), 70.3 for the KOOS PS (achieved by 68% of patients), and 70.7 for the KOOS JR (achieved by 70% of patients). CONCLUSIONS The present study provided useful MCID, MDC, and PASS thresholds for the KOOS Pain, PS, and JR for patients with OA. The diagnosis-specific metrics established herein can serve as benchmarks for clinically meaningful postoperative improvement. Future research and quality assessments should utilize these OA-specific thresholds when evaluating outcomes following TKA. Doing so will enable more accurate determinations of operative success and improvements in patient-centered care. LEVEL OF EVIDENCE Prognostic Level II .

Abstract
BACKGROUND The present systematic review investigated the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient-acceptable symptom state (PASS) of several frequent and established PROMs used to assess patients who have undergone TKA. This study was conducted according to the 2020 PRISMA statement. METHODS In September 2023, PubMed, Web of Science, and Embase were accessed with no time constraint All clinical studies investigating tools to assess the clinical relevance of PROMs used to evaluate patients having received TKA were accessed. Only studies which evaluated the MCID, PASS, or SCB were eligible. The PROMs of interest were the Forgotten Joint Score-12 (FJS-12), the Oxford Knee Score (OKS), the Knee Injury and Osteoarthritis Outcome Score (KOOS) and its related subscales activity of daily living (ADL), pain, quality of life (QoL), sports and recreational activities, and symptoms, the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) score, the Knee Society Score (KSS) and related function score, and the Short Form-12 (SF-12) and Short Form-36 (SF-36). RESULTS Data from 29,737 patients were collected. The overall risk of bias was low to moderate. The great variability of thresholds for MCID, SCB and PASS between questionnaires but also between investigated aspects was noted, whereby MCIDs for the SF-36 appear lower than for knee-specific questionnaires. CONCLUSION Despite its critical role from a patient's perspective, the dimension of SCB is still neglected in the literature. Moreover, thresholds for the different concepts need to be condition-specific. We encourage authors to specifically report such data in future studies and to adhere to previously reported definitions to allow future comparison. Level of evidence Level IV, systematic review and meta-analysis.
