Summary

Multimodal therapy significantly improved quality of life and function in patients with knee osteoarthritis before total knee arthroplasty (TKA). This pre-surgery optimization may enhance surgical outcomes and patient recovery.

Area of Science:

  • Orthopedics
  • Rehabilitation Medicine
  • Public Health

Background:

  • Psychosocial health is increasingly recognized as a critical factor influencing patient outcomes following total knee arthroplasty (TKA).
  • Osteoarthritis of the knee joint often leads to significant reductions in quality of life and physical function.
  • Optimizing patient condition before TKA is crucial for maximizing surgical success and long-term functional recovery.

Purpose of the Study:

  • To evaluate the impact of a 6-week multimodal therapy program on the quality of life and functional status of patients with knee osteoarthritis.
  • To determine if patient response to multimodal therapy prior to TKA influences the overall functional outcome of the surgery.

Main Methods:

  • A prospective study involving 526 patients diagnosed with knee osteoarthritis.
  • Participants underwent a 6-week multimodal therapy program including exercise, physiotherapy-led education, and dietitian-led weight management lectures.
  • Outcomes were assessed using standardized measures such as SF-12, Oxford Knee Score (OKS), Visual Analogue Scale (VAS) for pain, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores.

Main Results:

  • The multimodal therapy program resulted in significant improvements across all measured outcomes, including SF-12, OKS, VAS pain scores, and WOMAC scores.
  • Patients demonstrated enhanced psychological scores following the multimodal intervention.
  • These improvements suggest that the therapy effectively prepared patients for TKA.

Conclusions:

  • Multimodal therapy is an effective intervention for improving quality of life and functional status in patients with knee osteoarthritis.
  • Optimizing patients' psychological and physical condition through multimodal therapy before TKA can potentially enhance surgical outcomes and overall functional recovery.
  • This approach offers a valuable strategy for pre-habilitation in patients undergoing total knee arthroplasty.
