THE MOTIVATION
cliff.

Nobody warns you about week three. The crisis is over, the get-well messages have stopped, work expects you back at full speed — and the recovery still needs an hour of tedious, invisible work every day, with nothing dramatic to show for it. This is the week adherence quietly dies. Not from pain. From boredom.

What the protocols focus on now

By this window, published protocols like the Cambridge University Hospitals guidance are typically working on:

• Normalising the walk — off crutches when your protocol's criteria are met, with a gait worth keeping.
• Range of motion — holding full extension while flexion keeps climbing.
• Early strength — controlled, closed-chain work (think leg presses within a protected range, if prescribed) rather than anything heroic.
• The quiet skills — balance and control work that looks like nothing and matters enormously later.

None of it is cinematic. All of it compounds.

Swelling now speaks in trends

A knee that puffs up after a bigger day and settles overnight is behaving the way published resources describe as expected at this stage. What deserves attention is the trend: swelling that ratchets upward across several days, or pain that's climbing rather than slowly fading, is worth a message to your physio — that's load management, and it's literally their job to adjust it.

The adherence problem, honestly

Here is the uncomfortable arithmetic of this phase: you might see your physio for thirty minutes a fortnight. The other 20,000 minutes are yours. Research on home exercise programs consistently finds adherence drops once novelty wears off — and week three is exactly where that curve bends.

What tends to help is structural, not motivational:

• Anchor the exercises to something that already happens daily — after the morning coffee, before the shower. Habits attach better than schedules.
• Track showing up, not performance. "Did the session" is a better daily metric than any number on it. Streaks reward consistency; pain-grinding isn't the goal.
• Make the day visible. Day 17 of a 270-day arc feels endless in your head and manageable on a wall calendar with crosses on it.
• Tell your physio when adherence slips. They would rather rescale the program than have you silently do 40% of it.

Ask your physio this week

• "What are the actual criteria for coming off crutches / progressing my exercises?"
• "Which exercise is the one not to skip when life happens?"
• "What does 'too much' look like for me specifically?"
