The Lateral Approach to the Valgus Knee. Surgical Technique and Analysis of 53 Cases with Over Two-Year Follow-Up Evaluation.
Valgus deformity correction poses a major challenge in total knee arthroplasty (TKA). The standard medial approach has many technical limitations and disadvantages that include patellofemoral maltracking and subsequent patellar problems. The lateral approach has been developed and utilized successfully in 79 cases (53 with over two-year follow-up evaluation) since 1980. The biomedical rationale of the approach is sound, and addresses the pathologic anatomy of fixed valgus deformity. Surgical technique is direct, anatomical, more physiologic, and maintains soft-tissue integrity. The "lateral release" is performed as part of the approach. Patellofemoral tracking and alignment stability are optimized and medial blood supply preserved. Clinical experience has shown the approach to be more aesthetic and results objectively superior. Scores have been good/excellent in 94.3% of cases. Knee stability is enhanced with the use of nonconstrained prostheses in this difficult group of patients. The lateral approach is recommended as the "approach of choice" for fixed valgus deformity in TKA.
