  • Title: High tibial osteotomy and ligament reconstruction for varus angulated anterior cruciate ligament-deficient knees.
    Author: Noyes FR, Barber-Westin SD, Hewett TE.
    Journal: Am J Sports Med; 2000; 28(3):282-96. PubMed ID: 10843117.
    Abstract:
    In a consecutive series, we treated 41 young patients who had anterior cruciate ligament deficiency, lower limb varus angulation, and varying amounts of posterolateral ligament deficiency. Seventy-three percent of the patients (N = 30) had lost the medial meniscus and 63% (N = 26) had marked articular cartilage damage in the medial compartment. All patients were treated with high tibial osteotomy and, in the majority (N = 34), anterior cruciate ligament reconstruction a mean of 8 months later. Posterolateral reconstructions were also required in 18 knees. A 100% follow-up was obtained at a mean of 4.5 years after osteotomy. Gait analysis testing was done in 17 knees before and after osteotomy. At follow-up, a reduction in pain was found in 71% (29 knees); elimination of giving way, in 85% (35 knees); and resumption of light recreational activities without symptoms, in 66% (27 knees). The patient rating of the knee condition was normal or very good in 37% (15 knees) and good in 34% (14 knees). The mean Cincinnati Knee Rating Score significantly improved from 63 to 82 points. The mean adduction moment, 35% higher than controls preoperatively, significantly decreased to below normal values postoperatively. Correction of varus alignment was maintained in 33 knees (80%). We recommend osteotomy in addition to ligament reconstructive procedures in these knees with complex injury patterns.
