NCT04224376

Brief Summary

The investigators designed a prospective randomized trial to evaluate whether an app based active muscle training program (GenuSport) can improve the postoperative strength by starting rehabilitation immediately after primary anterior cruciate ligament (ACL) reconstruction surgery as already shown for patients who underwent total knee arthroplasty. To the investigators knowledge this is the first study analyzing immediate postoperative serious gaming based training with the GenuSport device based on strength improvement.

Outcome Measures

Primary Outcomes (1)

  • Absolute and relative change in maximum strength

    Primarily, change in maximum strength was analyzed both, as an absolute difference between week 6 and pre-surgery value (6 weeks - pre-surgery) and as a relative change (6 weeks / pre-surgery).

    6 weeks

Secondary Outcomes (5)

  • Change in clinical outcome

    6 weeks

Study Arms (2)

Conventional rehabilitation

NO INTERVENTION

Normal postoperative treatment protocol with physiotherapy after ACL surgery

Serious Gaming

EXPERIMENTAL

In the training group each patient was additionally provided with a GenuSport knee trainer device (prototype plus tablet with software application) with the active knee extension training program for 6 weeks. Other postoperative treatment was identical.

Device: App based Serious Gaming with the Genu Sport knee trainer

Interventions

The Genu Sport knee trainer has a strength monitoring unit with three integrated sensors which is placed in the popliteal area and a tablet with the application which allows to transfer the raised force into the game modus. Each training session in our study takes around 5 minutes and is performed autonomously by the patient in his bed with 45° degrees of upper body evaluation while the patient holds the tablet in both hands. By simply pushing his knee downward onto the measuring unit the patient can apply the force.
