About this trial

In the present project, the framework conditions of outpatient rehabilitation at the Bonn Center for Outpatient Rehabilitation will now be used to prove whether sports science-controlled strength and BFR training has a similar effect in the postoperative rehabilitation phase. Strength and BFR training in medical training therapy complements daily exercise therapy in order to ensure implementation in the guideline-based rehabilitation process. . The interventions are carried out as part of the exercise therapy units in outpatient rehabilitation ETM01 following the RTS hip and knee TEP basis KTL 2020.

Treatments tested in this trial

Sham-BFR
Other intervention
The exercise protocol provides for units of approx. 25 minutes of BFR training five times a week as part of medical training therapy. Based on the initial strength measurements prior to rehabilitation, the training phase of the intervention group starts with 30% of the 1RM (calculated from the force-velocity profile) and 70% LOP in the operated leg and 75% of the 1RM (calculated from the force-velocity profile) in the unoperated leg. The patients are randomized into 2 groups: 1) intervention group, which receives a daily intervention with an occlusion pressure and the 2) control group, which receives a daily "Sham-BFR" intervention with an occlusion pressure of 20mmHg.
