To study the functional outcome of lateral wedge closing osteotomy using stapler for osteoarthritis of knee

Abstract

Background: To assess functional result in knee osteoarthritis treated with a Lateral Closed Wedge High Tibial Osteotomy.Method: Thirty patients with various stages of knee osteoarthritis were treated with lateral wedge high tibial osteotomy under spinal anaesthesia. HKA axis collected post-operatively and at 06 to 09 month follow up to evaluate axis rectification and varus deformity. The Knee Society Score was used to assess the functional result.Results: According to the Oxford knee score, 80% (n=24) of our patients had outstanding outcomes, 14% (n=4) had good outcomes, and 6% (n=2) had fair outcomes.Conclusion: Lateral close wedge osteotomy is a low-cost treatment that enables anatomical axis alignment without requiring a total knee replacement and also avoids further advancement of knee osteoarthritis.
