This study will test a protocol to implement simultaneous physiotherapy and orthopedic surgeon interdisciplinary care for patients undergoing knee replacement surgery. These interdisciplinary sessions will help tailor personalized goals, involving the patient as a key member of the team.

The purpose of this project is to test a quality improvement protocol to improve outcomes following knee arthroplasty surgery utilizing simultaneous physiotherapy and orthopedic surgeon interdisciplinary care. In an era of increasing demands on health care budgets, it is vital to improve quality of care without substantially increasing its cost. This study will focus on a quality improvement strategy that aims to redeploy existing resources to achieve higher quality care without substantially altering costs. This interdisciplinary approach involves establishing a high functioning team that includes the patient as a pivotal member and builds collaboration in the pre-operative period that can be leveraged in the post-operative period to achieve optimal outcomes. This differs from traditional, siloed care for knee arthroplasty.

Participants will be involved in usual care surrounding knee arthroplasty which includes education sessions and pre-habilitation pre-operatively and rehabilitation post-operatively. Participants will also attend two interdisciplinary sessions at 2 months and 1 month prior to surgery to outline expectations, explore patients' questions and concerns, set expectations for the next interdisciplinary session, and ensure goal congruence between all members of the team. At each of these sessions a physical assessment will also be completed by the orthopedic surgeon and physiotherapist. Following surgery, participants will attend four more interdisciplinary sessions at 2 weeks, 6 weeks, 3 months, and 6 months post-operatively. These sessions will address safety and medical issues, revisit patient expectations, reinforce care team expectations, focus on a personalized rehabilitation plan, and ensure goal congruence between the various team members. The physical assessment will also be repeated.

The objectives of the study are as follows:

1. Evaluate the feasibility (e.g., recruitment and retention, administrative and participant burden, lived experiences) of treating knee arthroplasty patients through a novel interdisciplinary program aimed to optimize recovery among patients; and
2. Estimate the size of the program's effect on biopsychosocial outcomes among community-dwelling individuals undergoing knee arthroplasty and rehabilitation.

The hypotheses of the study are as follows:

1. The protocol will establish proof-of-concept, and demonstrate sufficient feasibility to support a future full-scale multi-site RCT.
2. Simultaneous physiotherapy and orthopedic surgery interdisciplinary care (SPOSIC) will improve the primary outcome of functional disability, as measured by the 12-item Oxford Knee score (OKS), and improvements will also be shown in the secondary outcomes of pain, participation in social roles, health-related quality of life, and mobility.
