PURPOSE: To compare the gait characteristics of unicompartmental knee arthroplasty (UKA) with total knee arthroplasty (TKA) performed on the same patient. MATERIALS AND METHODS: Twelve female patients with advanced degenerative arthritis of both knee joints were enrolled for the study group. The mean age was 70.3 (64-74) years old. One side of the knee joint had been replaced with UKA and the other side with TKA. The mean follow-up period was 11.8 months for the UKA side and 14.8 months for TKA side. The clinical and radiographic evaluations were performed. The gait features of the study group were assessed using computerized gait analysis. Seven age-matched healthy female volunteers (14 knees) were included as the normal control group. RESULTS: The clinical and radiographic results improved after joint replacement in both groups. The postoperative gait was almost normalized regardless of the type of surgery performed, with the exception of some parameters including the walking speed, mean pelvic tilt, knee flexion at initial contact, peak knee flexion, knee flexion between initial contact and loading response, knee flexion between initial swing phase and mid-stance phase and ankle 3rd rocker. Knee flexion at the initial contact of UKA and TKA groups was similar, and was different from that of the normal control group. At the loading response, the amount of knee flexion was similar between the three groups. Kinetic data of the first peak vertical ground reaction force and hip extension moment at loading response were better in the UKA group. CONCLUSION: The gait features were normalized in both groups. The UKA group was better normalized than the TKA group in terms of the aspect of the gait features, whereas TKA group showed better correction of deformities.

Trigger finger is a common disease particularly in the middle aged women. A very rare case in which an adult man had 10 trigger fingers was experienced. He was treated with local steroid injections in both thumbs, but trigger finger disease has been aggravated in every digit of both hands. We performed an early operative treatment. Three months after the operation, the patient could perform his work without discomfort in his hands and showed normal range of motion in all fingers.
