Summary
This pilot study shows that same-day discharge is feasible for knee replacement patients with osteoarthritis. Early recovery and pain management enable safe discharge and positive outcomes.
Area of Science:
- Orthopedic Surgery
- Rehabilitation Medicine
Background:
- Medial compartment osteoarthritis presents significant pre-operative pain and dysfunction.
- Unicompartmental knee replacement is a viable surgical option for select patients.
Purpose of the Study:
- To assess the feasibility and safety of same-day discharge for patients undergoing unicompartmental knee replacement.
- To evaluate the early recovery, pain levels, and functional outcomes of patients discharged within 24 hours.
Main Methods:
- A pilot study involving seven patients with medial compartment osteoarthritis.
- Patients underwent medial unicompartmental knee replacement via a short incision.
- An accelerated recovery program included immediate post-operative mobilization, pain control, physiotherapy, and self-assessment.
Main Results:
- All patients, except one due to administrative error, were discharged the day after surgery.
- Average post-operative pain score at 2 weeks was 2/10.
- At 6 weeks, patients achieved an average knee flexion of 125 degrees, walking independently and pain-free.
Conclusions:
- Same-day discharge following unicompartmental knee replacement is feasible and safe.
- The accelerated recovery protocol supports early mobilization and positive functional outcomes.
- This approach may improve patient throughput and recovery in knee replacement surgery.
