The purpose of this study was to evaluate the validity and reliability of the Clinician Rated Drop Vertical Jump Scale (CR-DVJS) in a population of patients following anterior cruciate ligament reconstruction (ACLR). Patients completed two drop vertical jump tasks at 6 and/or 12-months post-operative. One task was recorded using a motion capture system. Four individuals of varying clinical experience served as raters for the CR-DVJS. Rater scores of valgus collapse did not correlate strongly with motion capture measures of knee abduction moment or angle. However, CR-DVJS scores of trunk and knee flexion did demonstrate an association with 3D measures of trunk (rho=0.4-0.5) and knee (rho>0.5) flexion angle. Intraclass correlation coefficients suggested poor to good (0.4-0.9) inter-rater reliability of overall score, moderate (0.5-0.75) or good (0.75-0.9) intra-rater reliability, and good to excellent (0.75->0.9) within session test-retest reliability. Further studies are required to draw definitive conclusions prior to clinical implementation.
