In the presented study the question was evaluated if--after rotational knee arthroplasty--range of motion must be restored at discharge or if range of motion can also be restored with delay during the first postoperative year.
A retrospective study was performed on 45 patients. These had been rehabilitated with a specific therapeutical concept which did not include early restoration at discharge of complete range of motion as the key principle.
The mean range of motion was 60 degrees +/- 21 degrees at discharge. At the date of presentation 12 to 18 months postoperatively the mean range of motion had improved to 110 degrees +/- 19 degrees.
The presented study indicates that complete restoration of range of motion after rotational knee arthroplasty may not necessarily be restored at discharge.
