Knee flexion after rotational knee arthroplasty

Aim of the study: In the presented study the question was evaluated if afte r rotational knee arthroplasty - range of motion must be restored at discha rge or if range of motion can also be restored with delay during the first postoperative year. Method: A retrospective study was performed on 45 patie nts. These had been rehabilitated with a specific therapeutical concept whi ch did not include early restoration at discharge of complete range of moti on as the key principle. Results: The mean range of motion was 60 degrees /-21 degrees at discharge. At the date of presentation 12 to 18 months post operatively the mean range of motion had improved to 110 degrees +/-19 degr ees. Conclusions: The presented study indicates that complete restoration o f range of motion after rotational knee arthroplasty may not necessarily be restored at discharge.
