[Long-term results of the tibial head pendulum osteotomy in varus and valgus gonarthrosis in the elderly].

Proximal tibia-head osteotomy is an approved surgical method for the treatment of unilateral knee arthrosis. In a follow-up examination of 44 patients with 56 operated knees the long-term results more than 10 years after surgery are evaluated in older patients with varus and valgus arthrosis. It can be demonstrated that, if the indication is right, excellent long-term results can be expected, also for older patients with unilateral gonarthrosis. A fixation with metal implants seems to be unnecessary, and the complication rate is low.
