Comparison of Knee Joint Position Sense, Balance and Physical Function in Patients with Knee Osteoarthritis and Age-Sex Matched Normals

Objective: To understand about knee joint position sense, balance and physical function in patients with knee Osteoarthritis. Methods: 25 subjects with grade II osteoarthritis and 25 age- sex matched normals participated. Joint position sense was assessed with inclinotrac digital sensors at 30 and 45 degrees of knee flexion, balance with CTSIB using a Balance Master; Physical Function by WOMAC scale.Results:Knee joint repositioning error was (39.48 ± 6.80) and (32.47 ± 1.78) and (52.80 ± 7.29) and (46.73 ± 2.39) at 30 and 45 degrees of knee flexion, Sway velocity difference of (1.53) and (1.04) and WOMAC score for Osteoarthritis patients and matched normals respectively were statistically significant with p value (<0.005). Conclusion: Joint position sense, balance and physical function were affected severely in the osteoarthritis group.
