Return to sports after knee replacement

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This amendment expands an ongoing follow-up protocol to add structured, level-based functional testing used in sports orthopaedics to patients after knee arthroplasty. Each participant's prior sport level is recorded with a structured history and then put through level-specific, validated functional tests; participants must pass Level 1 before proceeding to higher levels. The tests are modeled on established stepwise concepts (e.g., Keller et al.) to provide objective, performance-based criteria rather than solely clinician judgment. Patients who cannot understand the procedures or who do not participate in sports are excluded from the testing protocol.
