ABSTRACT
BACKGROUND: The lower extremity functional scale (LEFS) is a patient-reported outcome measure for assessment of lower extremity function. It has been validated in adults but not in children or adolescents. METHODS: Patients 8 to 18 years of age who were treated for a lower limb fracture, injury, or other conditions were invited to join the study. LEFS and Pediatric Quality of Life Inventory 4.0 Generic Core Scales (PedsQL) were administered. Reliability and validity of the LEFS were determined for the entire cohort and for 2 age groups (children: 8 to 12 years; adolescents 13 to 18 years) using PedsQL as comparison. RESULTS: A total of 178 patients were recruited into this study. In the entire cohort, internal consistency of LEFS was excellent (0. 972) with acceptable floor (0%) and ceiling (12%) effects. Correlation between LEFS and PedsQL physical functioning component was high ( r =0.859). Construct validity was acceptable, with all 8 hypotheses demonstrating statistical significance. Factor analysis showed that item 15 (sitting for 1 hour) may contribute to measurement error in the pediatric population. Results remained similar when comparing the 2 age groups. CONCLUSIONS: The LEFS is overall an acceptable patient-reported outcome assessment of children and adolescents with various lower limbs disorders. LEVEL OF EVIDENCE: Level II.

Osteochondral allograft (OCA) transplantation has been used to treat a wide spectrum of cartilage deficiencies in the knee, including spontaneous necrosis of the knee. Studies reporting outcomes after OCA transplantation have shown reliable improvement in pain and return to activities of daily living. We describe a single-plug, press-fit technique for OCA transplantation with concomitant high tibial osteotomy to treat femoral condyle chondral defects in a varus knee. Pearls and pitfalls of this technique are presented; attention should be paid to correction of concomitant joint pathology and malalignment to facilitate osseointegration and survivorship of the allograft plug into host bone. Appropriate surgical timing and prompt allograft implantation help to maximize chondrocyte viability.
ABSTRACT
STUDY DESIGN: Prospective cohort study. OBJECTIVE: The purpose of this study was to evaluate the relationship between patient-reported experience measures (PREMs) and patient-reported outcome measures (PROMs) in adolescent idiopathic scoliosis (AIS) managed nonsurgically with bracing or observation. SUMMARY OF BACKGROUND DATA: PREMs and PROMs are increasingly used to assess the effectiveness of patient-centered health care provision. To date, no study has attempted to study the relationship between PREMs and PROMs in AIS. METHODS: All patients who visited our one-stop, tertiary center for AIS between 2020 and 2021, were asked to complete pairs of PREMs and PROMs questionnaires. PREMs were evaluated using our institution's outpatient experience survey adapted from Hospital Consumer Assessment of Healthcare Providers and Systems survey. PROMs were determined via the Scoliosis Research Society-22 revised (SRS-22r) and European Quality of Life Five-Dimension Five-Level (EQ-5D-5L) forms. RESULTS: In total, we included 730 patients who completed pairs of PREMs and PROMs questionnaires. 451 patients were treated by observation and 279 were braced. In the observation group, there was no association between patient experience and SRS-22r or EQ-5D-5L scores. In the brace group, improved SRS-22r were associated with higher PREM scores. In particular, having confidence and trust in treating physicians ( r =0.34), reporting that their worries and concerns were addressed during treatment ( r =0.34) and being taught self-care ( r =0.33, P <0.0001 for all) were most highly correlated with better SRS-22r scores. CONCLUSIONS: In patients with AIS treated with bracing, improved patient experience was positively correlated with better patient reported outcomes, especially if patients' concerns were addressed during treatment and they received supportive care and education on self-care. In contrast, patient experience did not correlate with PROMs in children and adolescents with AIS who were under observation.
