Summary
Restoring full range of motion after rotational knee arthroplasty is not essential at discharge. Delayed restoration of range of motion is achievable within the first year post-surgery.
Area of Science:
- Orthopedic surgery
- Rehabilitation medicine
Context:
- Rotational knee arthroplasty is a surgical procedure to replace the knee joint.
- Post-operative rehabilitation protocols vary, with some emphasizing early range of motion (ROM).
Purpose:
- To evaluate if immediate restoration of range of motion (ROM) is critical at discharge after rotational knee arthroplasty.
- To determine if delayed ROM recovery is a viable outcome within the first postoperative year.
Summary:
- A retrospective study analyzed 45 patients undergoing rotational knee arthroplasty with a rehabilitation concept not prioritizing early ROM.
- Mean ROM at discharge was 60° (±21°), improving to 110° (±19°) by 12–18 months post-surgery.
- This suggests that complete ROM restoration is not strictly required at discharge.
Impact:
- Challenges the necessity of aggressive early ROM targets in post-rotational knee arthroplasty rehabilitation.
- Suggests a more flexible rehabilitation approach may yield comparable long-term functional outcomes.
- Informs clinical practice regarding patient expectations and rehabilitation strategies for rotational knee arthroplasty.
