Abstract
This study was undertaken to determine clinical outcome after medial opening wedge osteotomy with Tlocking plate, with two- year follow up. Twenty-two patients (22 knees) who underwent medial opening wedge osteotomy with T-locking plate (stainless steel 316L, 6 holes) for treatment of varus malalignment of the leg between March 2005 and April 2008 were included in the study. The amount of correction ranged from 7° to 19° (mean, 9.77°). Clinical and radiographic findings were evaluated with VAS and the Lysholm score at sixth, twelfth and twenty- fourth months. Follow-up ranged from 18 to 37 months (mean, 2.1 years). Significant reduction was observed of VAS, from 4 (range: 3.5-5) to almost free of symptoms (1.0 to 0.5) at the twentyfourth month follow-up (P<0.01). Good results were achieved in the Lysholm score (P<0.01). Medial opening wedge osteotomy with T-locking plate is safe and efficient procedure for corrective varus deformity of knee. High tibial osteotomy, T-locking plate , medial opening wedge osteotomy, varus deformity.
Highlights
High tibial osteotomy was described by Jackson in 1958 as a means of treating medial unicompartmental arthrosis of the knee joint 1
High tibial osteotomy is indicated for the treatment of symptomatic medial compartment osteoarthritis and is generally reserved for patients up to 60 years of age 3
Twenty-two patients who underwent medial opening wedge osteotomy with T-locking plate [stainless 316L, 6 holes] for treatment of genu varus deformity and pain due to osteoarthritis of medial compartment of the knee or varus deformity causing chronic ligament instability of knee between March 2005 and April 2008 were reviewed in the Institute of Orthopedics, Lerdsin General Hospital, Thailand
Summary
High tibial osteotomy was described by Jackson in 1958 as a means of treating medial unicompartmental arthrosis of the knee joint 1. Numerous authors have demonstrated that osteotomies about the knee are an effective treatment modality and has relatively good long-term results 2. High tibial osteotomy is indicated for the treatment of symptomatic medial compartment osteoarthritis and is generally reserved for patients up to 60 years of age 3. The long-term effect of ligament injuries in active patients leads to progressive deterioration in the articular cartilage of the tibio-femoral joint and the development of medial compartment osteoarthritis 4. In genu varus deformity with medial compartment degeneration, high tibial osteotomy (HTO) can stop the progression of arthritis for several years 6. The best results following HTO are obtained when it is performed in early arthritis 7
