Operation
Axis Corrections — Procedure & Aftercare
A misalignment of the leg axis — a knock-knee (genu valgum) or bow-leg (genu varum) — leads to one-sided overloading of the knee joint. Over time, this promotes premature wear of the overloaded part of the joint; this is referred to as pre-arthrosis.
An axis correction (osteotomy) allows the load to be distributed evenly across the joint again. In the case of early, one-sided osteoarthritis, this can relieve the damaged part and delay joint replacement — the patient's own joint is preserved.
Surgical procedure
In an osteotomy, the bone near the knee joint is deliberately divided and fixed in the corrected position with an angle-stable plate. For a bow-leg, the correction is usually carried out via an opening osteotomy of the shinbone; for a knock-knee, generally via a closing osteotomy of the thigh bone. Precise planning is based on X-ray images of the entire leg axis.
Procedure & aftercare
- Fixation: angle-stable plate
- Weight-bearing: partial weight-bearing with two forearm crutches during the first weeks
- Full weight-bearing: as a rule after a few weeks, depending on bone healing
- Implant removal: if the implant causes discomfort, this is usually possible at the earliest after about one year
