Objective: The aim of this study was to compare functional performance, force sense of knee joint, kinesiophobia, quality of life, and activity level between patients with partial meniscectomy and healthy people. Methods: Twenty patients with partial meniscectomy within six months to three years postoperatively and 20 healthy were included in this study. Maximal voluntary isometric muscle strength of Quadriceps femoris muscle and force sense with the biofeedback device, quality of life with Western Ontario Meniscal Evaluation Tool, functional performance with stair up/down test, physical function with Knee Injury and Osteoarthritis Outcome Score-Physical Function Short Form, activity level with Tegner Activity Level scale, kinesiophobia was evaluated with Brief Fear of Movement Scale. Results: Range of motion, maximal voluntary isometric muscle strength of M. Quadriceps femoris, and force sense decreased in the operated leg compared with the non-operated leg (p<0.05). Maximal voluntary isometric muscle strength of M. Quadriceps femoris, functional performance, force sense, quality of life and physical function were lower in meniscectomy group compared to the healthy group (p<0.05). Range of motion, pain severity, kinesiophobia scores, physical activity level was similar in both groups (p>0.05). Conclusion: Considering the occurs functional deficient after arthroscopic partial meniscectomy, we suggest that patients need comprehensive evaluation and rehabilitation programs to support their recovery. Rehabilitation programs should be established considering deficiencies in proprioception, functional performance, quality of life, muscle strength, and physical function after partial meniscectomy.
