Fit-Joints: Getting Fit for Hip or Knee Replacement

Summary

Osteoarthritis leads to reduced independence and quality of life. Total hip replacement is a successful and cost-effective surgical intervention to relieve pain and improve functioning in patients with osteoarthritis. Research has shown that preoperative health status strongly predicts outcomes including physical function and hospitalization length after hip replacement surgery. Frail patients, in particular, are at greater risk of poor postoperative outcomes and could potentially benefit from interventions targeting an improvement in their health status prior to undergoing a hip or knee replacement surgery. Partnering with the YMCA and a multi-disciplinary team of healthcare providers, this pilot trial will examine the feasibility of a multi-modal intervention for frail patients that includes a supervised exercise program, vitamin D and protein supplementation, and a medication review. The results of this feasibility study will guide the design of a future multi-centre study, which if successful, could be developed into a routine model of care that is implemented in joint replacement programs across Ontario and ultimately improving the lives of frail seniors undergoing hip or knee replacement.

Conditions

• Hip Osteoarthritis
• Knee Osteoarthritis

Interventions

OTHER

Multi-Modal Frailty Intervention

Exercise: A physiotherapist will develop an individualized exercise program and schedule appointments with the patient at a physiotherapist clinic. Participants will be offered free YMCA membership. Cognitive-behavioural Change Strategy(CBCS) and education: Throughout the intervention, CBCS and education about exercise, hip or knee arthroplasty and osteoarthritis will be administered. Protein Supplement: Participants will be provided with 1-2 daily supplements (containing 20-40 gram protein, 1.5 g β-Hydroxy β-Methylbutyrate /serving) to be taken with a meal or on activity days within 3-hours of exercise. Vitamin D: All participants in the intervention arm will be provided with a supply of Vitamin D3 (1000 IU/day tablets) for the duration of the intervention period. Medication Review: A geriatrician will review the medications for patients in the intervention arm.

OTHER

Usual Care

Patients in the control arm will receive usual care which may include the recommendation to attend fitness classes before surgery, however these patients will not receive the more intensive assessment/intervention of the physiotherapist and other intervention components. Control participants will be asked pre-operatively and post-operatively to indicate whether or not they exercise, take protein or vitamin supplements. For participants in intervention and control groups will, 1) we will monitor the YMCA attendance and 2) participants will be instructed on the completion a dietary intake log (including days of the week and weekend days) that indicate the type of food and amount over a four-day period in order to calculate energy and micronutrient consumption.
