In this study, we report the clinical results of medial UKA in combination with patellofemoral arthroplasty (MUKA/PFA) in 7 cases of bicompartmental osteoarthritis. Seven patients who received MUKA/PFA between June 2011 and April 2012 were included into the study. There were 1 male and 6 females with an average age of 77 years at time of operation. All those patients were suffering end stage osteoarthritis of both medial and patellofemoral compartments, with obvious clinical and radiological findings. The average follow-up period was 7 months. Patients were clinically examined including JOA score and range of motion (ROM) and radiographs were evaluated.Purpose
Subjects and Methods
There is a large gap between UKA and TKA in terms of tissue preservation including bone stock and knee ligament. We have recently introduced bicompartmental UKA (Bi-UKA) to fill the gap and achieve more “physiological” knee than TKA. In this study, we report the short-term results of Bi-UKA. Thirty knees in twenty-nine osteoarthritis patients who underwent Bi-UKA from December 2010 to December 2013 (6 males and 23 females, average age of 75) were clinically and radiologically evaluated with an average observation period of 19 months. The operative indications were (1)confirmed diagnosis of medial and lateral osteoarthritis or osteonecrosis with preserved status of patellofemoral joint; (2)range of knee flexion greater than 110°; (3)flexion contracture less than 20°; (4)clinically stable knee in the frontal and sagittal plane; (5)correctable knee deformity with fine knee congruency. In all cases, fixed type UKA was implanted through a tibia dependent cut using a spacer block. Zimmer Uni and TRIBRID UKA (Kyocera Medical Corporation) were implanted in 18 and 12 cases, respectively.Purpose
