Summary
Distal femoral varus osteotomy effectively treats knee osteoarthritis and valgus deformity, with 83% good or excellent outcomes. This surgery is not recommended for rheumatoid arthritis or limited pre-operative knee motion.
Area of Science:
- Orthopedic Surgery
- Biomechanical Engineering
Background:
- Valgus deformity of the knee is often associated with osteoarthritis.
- Distal femoral osteotomy aims to correct alignment and alleviate pain.
Purpose of the Study:
- To evaluate the long-term outcomes of distal femoral varus osteotomy.
- To assess the efficacy of this procedure for various knee conditions.
Main Methods:
- Retrospective review of 23 distal femoral varus osteotomies in 21 patients.
- Evaluation using The Hospital for Special Surgery knee score.
- Follow-up averaged 4 years.
Main Results:
- Preoperative valgus averaged 18 degrees, corrected to 2 degrees postoperatively.
- 83% of knees rated good or excellent; 93% of osteoarthritis patients had good/excellent results.
- 86% of patients reported satisfaction; range of motion showed minimal improvement.
Conclusions:
- Distal femoral varus osteotomy is reliable for gonarthrosis with valgus deformity from osteoarthritis or trauma.
- The procedure is not recommended for rheumatoid arthritis or pre-existing limited knee motion.
- The surgery effectively corrects alignment and improves patient satisfaction in select cases.
