Why timing matters
In Alberta, the median wait for orthopaedic surgery is 58.8 weeks, and more than half of people waiting for a hip or knee replacement report their quality of life getting worse during the wait. Alberta Health Services funds post-operative physiotherapy for up to twelve weeks, with no referral and no out-of-pocket cost.
The research is consistent on one point: how strong the quadriceps is going into surgery predicts how well function recovers afterwards, at three months, six months, and a year. Prehabilitation has been shown to reduce complications and improve function in the first six months after surgery, and to meaningfully improve how people feel going into it. The effect is real and modest, honestly stated: a measurable edge in the window you can control.
Research on patient satisfaction after knee replacement also shows that when people are unhappy a year on, the most common reason is not the surgery itself but the gap between what they expected to be able to do and what they can do, with kneeling, squatting, and walking distance topping the list. Setting expectations honestly, and training for your specific goals, is part of the work.
