Patellar instability is a frequent knee problem and relates to anterior knee pain [1–3]. Patellofemoral (PF) joint laxity is a multifactor problem that depends on the active stabilization from the quadriceps muscles, the passive stabilization from the ligaments and retinacular tissue in the PF joint, and the static stabilization from the articular geometries of the distal femur and patella. The purpose of this study was to use a novel patellar laxity instrument to measure patellar laxity and to assess subject-to-subject variation in patellar laxity.
