Runners with noisy knees after surgery: Is it related to symptoms?

Introduction: Knee crepitus can be defined as grinding, cracking or popping sounds in and/or around the knee joint (noisy knees). Many clinical practice guidelines include a diagnostic criterion for osteoarthritis. In setting, patients frequently ask whether they should concerned about crepitus, and may develop maladaptive beliefs movement behaviours attempting to avoid noise. We aimed explore is associated with outcomes runners history of surgery, population known at risk early Methods: Sixty-one (run ≥10km/week, ≥3 sessions/week) surgery (9±4 years) were recruited (age 33±7 years, 30% women) from TRAiL cohort (TRAjectory heaLth runners). Presence (never, rarely, sometimes, often, always) was assessed using single item injury Osteoarthritis Outcome Score (KOOS) “Do you feel hear clicking any other type noise when your moves?”. Self-reported patellofemoral symptoms (KOOS-Patellofemoral subscale), overall function (KOOS4) fear (Tampa Scale Kinesiophobia). Performance-based hop-for-distance maximum number side-to-side hops 30 seconds. Spearman rank correlation coefficients cross-sectional association between outcomes. Results: Seventy-two percent experienced (always=8%, often=23%, sometimes=26%, rarely=15%, never=28%). had moderate significant worse (rho = -0.44; 95%CI -0.62 -0.20) -0.52; -0.68 -0.29). found small non-significant associations greater -0.17; -0.41 0.08), lower hop distance -0.12; -0.36 0.14), -0.37 0.13). Discussion: young adult common (>70%) function. Previous research older adults (>45years) suggests that development symptomatic osteoarthritis, symptoms, structural osteoarthritis features joint. Future longitudinal analyses will elucidate are more likely Impact application field:•Knee highly prevalent Our findings help explain why have negative regarding their noisy knees.•Knee simple sign could easily clinically by sports medicine practitioners surgery.
