About

Immediate rehabilitation after total knee arthroplasty (TKA) differs in terms of volume, intensity but also type of treatment. Continuous passive motion after TKA is so far only investigated for replacing physiotherapy. This study is conducted to investigate CPM when it partially replaces group physiotherapy in terms of functional and patient-reported outcomes.

Full description

The aim of this study is to analyze the value (knee function, pain, and quality of life) of continuous passive motion (CPM) after total knee replacement (TKR), when it partially replaces group physiotherapy (PT) in inpatient rehabilitation to save human resources. Patients are randomized to CPM group, consisting of 3 daily sessions of 20 minutes each, or to group PT, consisting of 25 minutes physiotherapy in groups 5 days weekly. Multimodal rehabilitation does not differ for both groups throughout the 3-week rehabilitation stay.

Primary outcome is the Staffelstein Score, German standard score in rehabilitation. Secondary outcomes are Oxford Knee Score (OKS), active and passive range of motion (ROM), and pain on visual analogue scale (VAS). Return to work is assessed by post-operative days.
