Abstract:
OBJECTIVE:The unicondylar prosthesis replaces the medial femerotibial compartment only, the part presenting with osteoarthritic changes. The remaining compartments of the knee present less osteoarthritic changes and thus can be preserved. INDICATIONS:Osteoarthritis of the medial femorotibial compartment is the ideal indication for unicondylar arthroplasty. The knee should show an intraarticular deformity, which means the malalignment is caused by the osteoarthritic changes of the medial compartment. CONTRAINDICATIONS:Malalignment of >5°, flexion contracture of >10°, mediolateral instability and symptomatic osteoarthritis of a second compartment should be considered as contraindications for unicondylar arthroplasty. SURGICAL TECHNIQUE:In the current article, implantation of the BalanSys® system is presented. Femoral bony resection is solely ligament balanced. The technique allows creation of an optimal extension and flexion gap. Bone cuts were performed using a soft tissue tension device for measuring the extension and flexion gap. POSTOPERATIVE MANAGEMENT:Full weight bearing on crutches is allowed immediately after surgery without restriction in flexion. Crutches are recommended for 4 weeks in order to compensate for neuromuscular deficits. Anticoagulation is recommended for 11-14 days according to the AWMF guidelines (S3 guidelines, Release:15 October 2015). RESULTS:The clinical follow-up after 2 years showed 87 ± 13 points in the knee score and 80 ± 10 points in the function score. The mean range of motion increased from 113°±24° prior to surgery to 122°±23° after surgery. A preoperative extension deficit of 10° was observed in 9 patients and reduced postoperatively in 3 patients.
