We report a case of familial spastic paraplegia accompained by recurrent dislocation of the patella who received a patellectomy to relieve the knee pain. The patient is a 55 years old female, and has weakness and numbness in both lower legs which started to appear when she was 20 years old, gradually changing to a deformity of the X legs. The traumatic dislocation of the patella in the right knee at the age of 24, triggered the recurrent dislocation and chondromalacia patellae. In order to relieve the motion pain of the knee and to improve ADL disturbance, we performed a patellectomy following the method of West and Soto-Hall which is better for maintaining the function of the quadriceps muscle. As a result, the patient became able to raise the right leg straight. Now the patient has acquired the ability to walk as before the operation by the use of a knee brace. Familial spastic paraplegia is a progressive disease, so someday she may become completely unable to walk by herself, but she is satisfied with the results of the operation which was selected carefully.
