An interventional study of Return to sports test in Knee Osteoarthristis and Arthroplasty Replacement, Knee, sponsored by Technical University of Munich. Recruiting at 1 site in Germany. Open to participants aged 18 Years to 85 Years. Per ClinicalTrials.gov, last updated 2025-09-19.
Sponsored by Technical University of Munich · Not applicable, Interventional, and Screening
The ability to return to sports after joint arthroplasty is increasingly becoming an important factor for patients in terms of their perceived quality of life. In sports orthopaedics, standardized functional tests have already been established - particularly for anterior cruciate ligament injuries - to assess athletic performance and prevent re-injury. These tests allow a stepwise evaluation of a subject's physical readiness for sports.
In the field of arthroplasty, and despite increasing sports activity among patients with joint arthroplasty such structured assessment is still lacking. As a result, patients with arthroplasty typically resume sports activities based solely on individual recommendations from the surgeon or treating therapist. However, an objective evaluation of sports capability is currently not available.
Therefore the amendment intends to expand the current testing protocol of the already registered and ongoing study (Protocol ID: UBonn_TKA_FollowUp) to include additional standardized, evidence-based return-to-sprort-tests.
These return-to-sports-tests are based on validated procedures commonly used in sports orthopaedics, particularly following the stepwise testing concept described by Keller et al..
Initially, the participant's individual sport level is determined via structured anamnesis. This is then followed by level-specific functional testing. Participants who do not perform Level 1 testing correctly will not proceed to Level 2 testing -even if their anamnesis suggests a higher sport level. This stepwise approach ensures safety and prevents injury during the testing process.
Technical University of Munich is the lead sponsor of 315 studies on the registry; 55 are open to participants now.

Level of sports 1-4
Levels of sports are divided into four levels: 1. Sports without jumping; 2. Dynamic sports without pivoting or abrupt stopping movements; 3. Sports involving lateral movements and moderate pivoting or stopping motions (less intense than in Level 4); 4. Sports with jumping, rapid pivoting, and sudden stopping movements.
