Abstract
OBJECTIVE: Three methods of surgery used in the treatment of knee osteoarthritis (OA) are mobile bearing unicompartmental knee arthroplasty (Oxford UKA), opening wedge high tibial osteotomy (HTO), and dome-type HTO. This article aimed to retrospectively compare these three methods in terms of outcomes for health status, patient satisfaction, and function. METHODS: Between 2003 and 2010, 255 knees of 235 patients underwent operations for medial knee OA. Three types of surgery were performed. Group 1 consisted of 109 knees of 94 patients who underwent Oxford UKA. Group 2 was made up of 36 knees of 36 patients who underwent HTO using circular external fixation, and Group 3 comprised 57 knees of 52 patients on whom opening wedge type HTO using locking plate fixation was performed. SF-36 and HSS knee scores were used to compare the functional outcomes among groups. RESULTS: Statistically significant differences were found between the preoperative and postoperative measures in all 3 of the treatment groups for physical function, physical role, pain, general health, vitality, social function, emotional role, and mental health according to SF-36 and HSS scores. In the 2nd group, the average correction of the mechanical axis deviation (MAD) was 38 mm with 11.7º along the femorotibial axis and 6.2º along the medial proximal tibial angle (MPTA). In the 3rd group, the average correction in the MAD was 28 mm with 9.7º along the femorotibial axis and 5.6º along the MPTA. All 3 of the treatment alternatives were observed to be sufficient. Satisfactory postoperative results were achieved in the UKA group in terms of social function and mental health, and the patients were able to achieve early rehabilitation and return to their previous life activities. CONCLUSION: UKA is the ideal option for patients who wish for the earliest possible return to social and recreational activities.
