Functional outcome of Unicondylar Knee arthroplasty in Unicompartmental osteoarthritis
Author(s): Shashank Singh, RK Beniwal and Saumya Agarwal
Abstract: Osteoarthritis is accepted as a major public health problem and is one of the major causes of impaired function that reduces quality of life worldwide. Pain relief, improved joint function, and joint stability are the main goals of therapy. Currently, the primarily surgical methods of treating unicompartmental knee arthritis include high tibial osteotomy, unicompartmental knee arthroplasty and conventional total knee arthroplasty. However, with the increasing concerns regarding the finite life span and post-operative functional recovery of these aforementioned procedures, the indications for UKA in the treatment of medial osteoarthritis were expanded. Advantages of UKA compared to TKA include decreased morbidity, smaller incisions, decreased blood loss, preservation of normal knee kinematics, rapid recovery, and shorter length of stay following surgery. 30 patients who met the inclusion criteria underwent Unicondylar Knee Arthroplasty and functional outcome was assessed using VERBAL pain score and WOMAC Score. Mean improvement in flexion at knee was 200, internal rotation was 0.730, external rotation was 7.700 and there was no deterioration in extension at knee at 1 year follow-up. There was decrease in mean VERBAL pain score and improvement in WOMAC score. Unicondylar Knee Arthroplasty has better functional outcome in terms of short surgical scar, short duration of surgery, short hospital stay, less blood loss, early mobilization, improved range of motion, lesser rate of complications.
