Abstract:
[Objective]To explore the short-term outcome and surgical technique of minimally invasive unicondylar knee arthroplasty(MIS-UKA) for medial compartmental osteoarthritis of the knee. [Methods]Forty-five patients(48 knees) with medial compartmental osteoarthritis of knee treated by MIS-UKA from May 2005 to December 2008 were reviewed and analyzed.The pain and range of motion(ROM) of the knees were evaluated by HSS score system before and after MIS-UKA.Pre-and postoperative alignment of the lower limbs was measured and compared.Surgery indications and surgical technique of MIS-UKA were also summarized.[Results]Forty-three knees in 40 patients were followed up for a mean time of 24 months(12-40 months).The pain over medial compartment of the knees was subsided or relieved in all cases.The post-operative ROM of the knees was 0?~135?(mean 120?),and alignment was 2? varus on the average(0?~6? varus).HSS score increased from 70(60~82) to 90(75~95).The good-to-excellent rate was 92%.[Conclusion]MIS-UKA is an effective method for medial compartmental osteoarthritis of the knee.Surgery indications and surgical technique are the key factors for the final results.
