Inpatient Versus Outpatient Rehabilitation After TKA

Not Applicable

Completed

• Conditions: Total Knee Arthroplasty
• Interventions: Other: outpatient rehabilitation; Other: inpatient rehabilitation

• Registration Number: NCT02120313
• Lead Sponsor: University of Rostock

Brief Summary

The purpose of this study is to compare the effectiveness of inpatient and outpatient rehabilitation following total knee arthroplasty. No studies exist that have evaluated these two rehabilitation programmes in a specific orthopaedic patient population with a focus on motor performance. We hypothesized that patients participating in outpatient care tend to be physically more active than patients in the rehabilitation clinic, leading to the assumption that outpatient rehabilitation has superior functional outcomes compared to the inpatient standard-of-care therapy.
