Abstract:
Purpose: This study was designed to evaluate the functional and radiological results of biplanar medial opening wedge high tibial osteotomy using Tomofix plate.
Patients and Methods : This study included 69 patients with medial unicompartmental osteoarthritis of the knee joint, their age ranged from 35 to 54 years with an average of 47 years, 38 were males and 31 females. Partial weight bearing exercises were allowed after the first week of surgery.
Results: Patients were followed up for a period ranging from 24 to 38 months with an average of 31 months. The American Knee Society Score was markedly improved in all patients from 61+/- 10 to 92+/- 5. The constitutional tibia vara angle improved from 5- 15 degrees to normal valgus angle 5-7 degrees. There was no recorded case of infection, non-union or metal failure.
Conclusions: The medial biplanar opening wedge high tibial osteotomy is a successful tool in correction of mal-alignment of the knee joint, early weight bearing, no bone grafting was required and complication free.
