Iliotibial band friction syndrome is a common cause of knee pain in long distance runners. The pain is caused by friction of the iliotibial band over the lateral epicondyle of the femur. Two hundred and twenty one cases were seen in a two year period. Tenderness over the lateral epicondyle associated with pain at 30 degrees of flexion on compressing the iliotibial band against the lateral epicondyle is diagnostic. Conservative treatment consisted of treating the cause, mostly training irregularities and the local inflammation mostly with steroid injections and rest. Nine cases failed to respond to conservative treatment and these were treated by surgical release of the posterior fibres of the iliotibial band.

Knee morbidity, knee extension torque and knee flexion torque were examined among 168 actively working carpet and floor layers and 146 painters. The study included a questionnaire concerning knee disorders and knee symptoms, a clinical examination of the knees and measurement of isometric knee extension and flexion torque. Knee accidents were reported more frequently by carpet and floor layers than by painters. Tenderness of the knees was noted to an equal extent in the two groups. Knee extension torques gradually decreased by increasing age among carpet and floor layers, but not among painters. Body weight and thigh girth were not related to age among carpet and floor layers, but gradually increased with age among painters. Analysis of covariance showed that the torques were most consistently related to thigh girth and age. In addition, the right knee extension torque was related to occupation and tenderness of the patellofemoral joint; the left knee extension torque was related to the knee pain index. These results suggest that occupational kneeling and internal derangement of the knee affect thigh muscles among actively working house builders.

In this report, we present a case of a 64-year-old woman who underwent revision of knee arthroplasty after failed unicompartmental knee arthroplasty (UKA). She underwent UKA (Biomet Oxford Phase 3) for right localized medial knee pain at the age of 53 and the postoperative course had been uneventful. Eight years after UKA, she had right knee pain that gradually worsened. Tenderness was present over the medial femorotibial and patellofemoral (PF) joints. Plain radiograph showed small osteophytes on the intercondylar eminence and in the lateral compartment. However, these findings were not severe. Although several causes of knee pain after UKA have been reported, none of those causes were found in this case, so the diagnosis of unexplained pain was made. We performed knee arthroscopy and it revealed severe osteoarthritis of the PF joint, bone attrition and exposure of subchondral bone of the medial part of the lateral condyle together with severe synovitis. Revision surgery was performed in the same operation. The postoperative course was excellent and the severe knee pain resolved after surgery. Several registries revealed that revision for unexplained pain was more common after UKA than after total knee arthroplasty. We pointed out the possible causes of unexplained pain including pathological conditions, which were present in our case. Revision surgery may be unsuccessful if the cause of failure is not adequately considered.
