Background: Patient-reported outcome measures are important to determine outcomes after orthopaedic procedures. There is currently no standard for outcome measures in the evaluation of patient outcomes after proximal hamstring repair. Purpose: To identify and evaluate outcome measures used after proximal hamstring repair. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was performed to identify all English-language articles assessing outcomes after proximal hamstring repair in PubMed, Embase, CINAHL via EBSCOhost, MEDLINE via OvidSP, and Web of Science between 2000 and 2019. After duplicates were removed, studies were selected using eligibility criteria established by the authors. Image reviews, anatomic/histology studies, literature reviews, surgical technique reports, systematic reviews, narrative reviews, case studies, and studies with <5 patients were excluded. Extraction, synthesis, and analysis of outcome measure data were performed using Microsoft Excel. Quality assessment of included studies was performed using Methodological Index for Non-Randomized Studies criteria. Results: After duplicate articles were removed, a total of 304 unique articles were identified and 27 met the inclusion criteria. The mean number of patients with proximal hamstring repairs per study was 40. The most frequently reported outcome measures were return to sport (14/27; 51.9%), custom survey/questionnaire (13/27; 48.1%), and isokinetic hamstring strength testing (13/27; 48.1%). Six of the 10 most commonly used outcome measures were validated and included Lower Extremity Functional Scale, 12-Item Short Form Health Survey, visual analog scale for pain, Perth Hamstring Assessment Tool (PHAT), Single Assessment Numeric Evaluation, and Tegner Activity Scale. Of those, PHAT was the only validated outcome measure designed for proximal hamstring repair. Conclusion: There is currently no consensus on the best outcome measurements for the evaluation of patients after proximal hamstring repair. We recommend an increased commitment to the use of return to sport, isokinetic strength testing, Lower Extremity Functional Scale, and PHAT when assessing such injuries. Future studies should aim to define the most reliable methods of outcome measurement in this patient population through consistent use of tools that are clinically relevant and important to patients and can easily be employed in a variety of clinical scenarios.

Background: The goal of treatment for a proximal hamstring avulsion (PHA) is an objectively restored muscle and a subjectively satisfied, pain-free patient at follow-up. Different self-reported and performance-based outcome measures have been used to evaluate recovery, but their validity is poorly investigated. Purpose: To investigate 1) the correlation between the commonly used self-reported outcome measurements, the Perth Hamstring Assessment Tool (PHAT) and the Lower Extremity Functional Scale (LEFS); 2) to what extent these scores can be explained by physical dysfunction as measured by performance-based tests; 3) whether performance-based tests can discriminate between the injured and uninjured extremity; and 4) which activity limitations are perceived by patients several years after the injury. Study design: Cohort study (Diagnosis); Level of evidence, 3. Methods: We included a consecutive series of patients treated for or diagnosed with PHA in our department between 2007 and 2016 having at least 2 tendons avulsed from the ischial tuberosity. Participants attended 2 study visits, answered questionnaires (PHAT, LEFS, and Patient-Specific Functional Scale [PSFS]), and performed physical performance–based tests (single-leg hop tests, single–step down test, and isometric and isokinetic strength tests). Results: A total of 50 patients were included (26 men [52%], 24 women [48%]; mean age, 50.9 years [SD, 9.8 years]). The mean follow-up time was 5.5 years (SD, 2.7 years), and 74% had been surgically treated. The correlation between PHAT and LEFS was strong ( r = 0.832) and statistically significant ( P < .001). Seven of the performance-based tests exhibited a statistically significant but weak correlation with LEFS (0.340-0.488) and 3 of the tests to PHAT (–0.304 to 0.406). However, only peak torque could significantly discriminate between the extremities. The activity limitation most commonly mentioned in PSFS was running (16 patients [32%]). Conclusion: Although PHAT and LEFS correlated strongly, the correlations between functional tests and the patient-reported outcome scores were weak, and most functional tests failed to discriminate between the injured and uninjured lower extremity in patients with PHA 5 years after injury. In general, patients alleged few activity limitations, but running difficulty was a common sequela after PHA.

Background: There is limited information on the clinimetric properties of questionnaires of activity limitation in people after ankle fracture.Objective: The purpose of this study was to investigate the clinimetric properties of the Lower Extremity Functional Scale, an activity limitation questionnaire, in people with ankle fracture.Design: This was a measurement study using data collected from 2 previous randomized controlled trials and 1 inception cohort study.Methods: Participants with ankle fracture (N=306) were recruited within 7 days of cast removal. Data were collected at baseline and at short- and medium-term follow-ups. Internal consistency and construct validity were assessed using Rasch analysis. Concurrent validity, responsiveness, and floor and ceiling effects were evaluated.Results: The Lower Extremity Functional Scale demonstrated high internal consistency (α&gt;.90). The variance in activity limitation explained by the items was high (98.3%). Each item had a positive correlation with the overall scale, and most items supported the unidimensionality of the scale. These findings suggest that the scale has high internal consistency and construct validity. The scale also demonstrated high concurrent validity and responsiveness in the short term and no floor or ceiling effects. However, the scale would benefit from more-challenging items, as evident at the medium-term follow-up.Limitations: This was a secondary analysis of existing data sets.Conclusion: The Lower Extremity Functional Scale is a useful tool to monitor activity limitation in people with ankle fracture up to the short-term follow-up. More- difficult items may need to be added to improve the responsiveness of the scale for longer-term follow-up.
