Purpose: This study was planned to compare the quadriceps muscle strength, knee joint proprioception, and quadriceps force sense between individuals with total knee arthroplasty (TKA) and healthy controls and investigate the relationship between quadriceps muscle strength, knee joint proprioception, and quadriceps force sense in individuals with TKA, in which joint proprioception is mostly provided by extra-articular proprioceptors. Methods: Forty-six individuals (mean age: 67, 80.4% female) who had undergone TKA surgery at least four months before and 46 age-matched healthy controls (mean age: 63, 73.9% female) were included in this study. Quadriceps muscle strength was assessed by maximal isometric contraction test, knee joint position sense (active and passive) with repositioning error test, and quadriceps force sense with force sensitivity test. An isokinetic dynamometer was used in all assessments. Results: In the total knee arthroplasty group, quadriceps strength (p
