Optimizing total knee arthroplasty recovery: the role of enhanced recovery after surgery (ERAS) protocols on clinical outcomes and patient satisfaction.

BACKGROUND

Knee osteoarthritis (OA) is a common degenerative condition that significantly affects quality of life. Total Knee Arthroplasty (TKA) is an effective treatment for end-stage OA, but recovery can be challenging. Enhanced Recovery After Surgery (ERAS) protocols aim to optimize perioperative care and improve outcomes.

METHODS

This prospective cohort study evaluated the impact of ERAS protocols on 300 patients undergoing primary TKA. Patients were divided into an ERAS group (n = 150) and a traditional care group (n = 150). ERAS included preoperative education, multimodal analgesia, early mobilization, and multidisciplinary care. Primary outcomes were postoperative pain, length of hospital stay (LOS), and complication rates. Secondary outcomes included functional recovery and patient satisfaction.

RESULTS

The ERAS group had significantly shorter LOS (3 vs. 7 days, P = 0.01) and lower blood transfusion rates (21.3% vs. 36.7%, P = 0.01). Postoperative pain scores were consistently lower in the ERAS group (P = 0.01-0.04). Functional recovery, measured by Knee Society Score, and patient-reported outcomes were significantly better in the ERAS group at 3, 6, 12, and 24 months (P < 0.01).

CONCLUSION

ERAS protocols significantly improve outcomes in TKA, reducing hospital stays and enhancing patient satisfaction and recovery, supporting their broader use in orthopaedic surgery.
