A Soft-Tissue Release Technique for TKA
Knee Surg Sports Traumatol Arthrosc; ePub 2016 Mar 3; Boettner, et al
Release of the iliotibial band and posterolateral corner provided excellent clinical results at a minimum 2-year follow-up and can be used safely for a "cookbook" approach to the valgus knee with up to 25° mechanical valgus alignment. This according to a study of 164 patients undergoing total knee arthroplasty by a single surgeon. Researchers found:
• Range of motion (ROM) increased from a preoperative flexion contracture of 4.7° and flexion of 110° to a postoperative mean flexion contracture of 0.1° and flexion of 128°.
• Mean hip-knee-ankle alignment was changed from 8.4° of mechanical valgus to 0.02° of varus alignment.
• Tibia component angle (MPTA) was 90.4°.
• WOMAC score, VF-12, UCLA and VAS significantly improved after surgery.
• 2 patients underwent revision surgery for instability.
