High tibial osteotomy for medial compartment osteoarthritis: a comparison of clinical and radiological results from closed wedge and focal dome osteotomies.
This study aimed to evaluate the clinical and radiological results of closed wedge osteotomy (11 knees) and focal dome osteotomy (14 knees) in cases of high tibial osteotomy undertaken for varus knee with medial compartment osteoarthritis. Clinical evaluation was performed using the Knee Society Score and no significant difference was seen between the two groups at final follow-up. Radiological evaluation was made on the basis of the pre- and postoperative mechanical axis, postoperative movement of the tibial axis, loss of correction at final follow-up and patellar height measured using the Insall-Salvati index. Statistically significant differences were seen with focal dome osteotomy compared with closed wedge osteotomy in the InsallSalvati index at final follow-up, the amount of correction loss and the change in tibial axis location. It is concluded that, in the treatment of medial compartment osteoarthritis by high tibial osteotomy, focal dome osteotomy is more beneficial than closed wedge osteotomy in not creating any additional deformity.
