We have examined the results of anterior cruciate ligament (ACL) reconstruction combined with high tibial osteotomy (HTO) for ACL-deficient and osteoarthritic knees done from 2003-2005.
The patients were one man and two women with an average of 55 years (range 48 to 62 years) at the time of surgery. The average period from the injury to the operation was 35 years (range 30 to 39 years). The average follow-up period after surgery was 17 months (range 9 to 24 months). All of the patients underwent ACL reconstruction using hamstrings combined with closed wedge HTO.
Evaluation was based on the Lachman test, Pivot shift test, radiographic documentation, Japanese Orthopedic Association osteoarthritis knee score (JOA score), and Lysholm score. Lachman test and Pivot shift test results improved from positive to negative. The average femorotibial angle (FTA) was 182° before surgery and 170° after surgery. Osteoarthritis had not progressed after the operation. Total JOA scores, and Lysholm scores were improved after surgery.
We concluded that ACL reconstruction combined with HTO was a useful procedure for improving the knee instability of ACL-deficiency and the pain of osteoarthritis in such cases.
