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 (less than0.005). Conclusion Joint position sense, balance and physical function were affected severely in the osteoarthritis group
