Abstract:

BACKGROUND: Soft tissue releasing is a major means of correcting knee flexion contracture, and the soft tissue releasing methods are different for different knee joint diseases and degrees of deformity. Ideal soft tissue balance can gain a clear functional recovery and deformity correction from severe knee flexion contracture after total knee arthroplasty.
OBJECTIVE: To study the proper handling of knee flexion contracture and soft tissue releasing in total knee arthroplasty.
METHODS: Twenty-six cases of knee deformity in 20 ° to 60 ° receiving primary total knee arthroplasty were retrospectively studies. Steps of soft tissue releasing and residue deformity after each step were recorded. Postoperative follow-up was 12 months on average.
RESULTS AND CONCLUSION: The 26 cases were recovered from knee flexion deformity after soft tissue release. Posterior capsular release was carried out in all cases to different extents, and the flexion deformity and postoperative range were corrected and greatly improved, respectively. These indicate that the posterior capsular release and lateral collateral ligament release can correct most of the flexion deformity, but increasing the distal femoral osteotomy is not necessary.
