High Tibial Osteotomy for Osteoarthritis of the Knee

High Tibial Osteotomy for Osteoarthritis of the Knee: a Randomised Controlled Trial

A prospective, randomised, controlled trial compared two different techniques of high tibial osteotomy with a lateral closing wedge or a medial opening wedge, stabilised by a Puddu plate. The clinical outcome and radiological results were examined at one year.

A prospective, randomised, controlled trial compared two different techniques of high tibial osteotomy with a lateral closing wedge or a medial opening wedge, stabilised by a Puddu plate. The clinical outcome and radiological results were examined at one year.

The primary outcome measure was the achievement of an overcorrection of valgus of 4°. Secondary outcome measures were the severity of pain (visual analogue scale), knee function (Hospital for Special Surgery score), and walking distance.

Exclusion Criteria:

• Symptomatic OA of the lateral compartment, rheumatoid arthritis, ROM <100, collateral ligament laxity, history of fracture of previous open operation of the lower limb and a flexion contracture > 10 degrees.
