A Case of Anterolateral Leg Pain After Total Knee Arthroplasty

Abstract

　　We report here a case of residual pain in the anterolateral part of the leg after total knee arthroplasty where the patient had difficulty recovering ambulatory function. The pain in the anterolateral part of the leg was considered to have occurred in combination with joint dysfunction, such as limitation in the range of motion of subtalar joint pronation and associated lateral thrust, as well as tendency towards the “no heel off” gait that is characteristic of knee osteoarthritis. Physical therapy and insole therapy performed to improve the range of joint motion and to correct the lateral force resolved pain in the short term and enabled the patient to resume activities including long-distance walking, weeding, and agricultural work. The possibility of developing pain in the lateral aspect of the leg after total knee arthroplasty due to impaired joint function and malalignment should be considered and physical therapy provided when needed.
