JointClass is the 20-minute class your surgeon didn't have time to give you. Knee, hip, and shoulder, from pre-hab through full recovery.
Learning what to expect before surgery is low-risk, and it may help most if you are anxious or unsure what to expect. A Cochrane review found it unclear whether pre-surgery education changes pain, function or complications, so treat this as preparation, not treatment (McDonald et al., 2014). Typical timelines; your surgeon's instructions come first.
Cochrane review of pre-op education for hip or knee replacement (2014): unclear whether it improves pain, function or complications over usual care; low-risk, and it may help people who are anxious or unsure what to expect (McDonald et al.). CMS data: 90-day readmission after TKA is 5–7% — over 9 in 10 patients recover without returning to the hospital. This class takes 20 minutes.
An AI can answer the moment you have a question, and that's genuinely useful. But it answers in general — it doesn't know your surgeon's protocol. Neither does this class: it lays out the typical road in the order you'll walk it, pre-hab, hospital, the first six weeks, full recovery, with sources on the page, so you know what to ask the people who are responsible for your care.
The class follows four stages of your surgery. So far the app has one written lesson, Preparing Your Home for Recovery; the other lessons are planned, not written yet. For now, each stage is covered in brief further down this page.
Select your procedure to see what the surgery involves, realistic recovery milestones week by week, and what most patients experience.
Total (TKA) and partial (UKA) knee arthroplasty. The most common joint replacement in the US — most patients go home same day.
Total hip arthroplasty (THA). Posterior and anterior approaches differ in precautions — your surgeon will tell you which applies to you.
Rotator cuff repair, total shoulder arthroplasty (TSA), and reverse shoulder replacement. Sling protocols vary by procedure.
No surprises. Here is what each stage actually involves.
The scariest moment in recovery usually isn’t the surgery — it’s the first time an exercise hurts and you wonder if you’re breaking something. Almost always, you’re not. This is the distinction your care team wishes every patient understood.
Protecting a joint that hurts is a good instinct — it kept you safe when the injury was fresh. But after a repair, the exercises your team prescribes are chosen to be safe for exactly where you are in healing. The soreness you feel doing them is usually tissue waking up and adapting, not tearing. The real trap is the opposite one: if you avoid moving because it’s uncomfortable, the joint stiffens, the muscle weakens, recovery stalls — and the fear quietly grows. Gentle, steady movement on your team’s schedule — a little more each day, paced by the plan rather than by how much it stings — is what breaks that cycle.
The hard part about this loop is that it’s nearly invisible from the inside. Avoiding a movement doesn’t feel like fear — it feels like being careful. And between appointments your team can’t see it either: on a checklist, “too sore today” and “quietly avoiding that one” look identical. That’s the honest case for measuring your exercises instead of just remembering them — it turns a feeling into something you and your care team can look at together, while there’s still time to change it.

And the other half of it
You will feel better before you are better. Those are two different dates, and the gap between them is wider than almost anyone expects.
Pain settles down early. The tissue underneath — tendon, bone, the repair itself — keeps rebuilding and gaining strength for months afterward, long after it stopped hurting. That is normal, and it is the part you can’t feel. So the risky moment isn’t the first week when everything aches and you’re careful. It’s the week you feel fine, decide you’re done, and go back to full load on a joint that is still catching up. Feeling good is not the finish line — it’s the middle. Keep going on your team’s schedule, not on how it feels.
General education, not medical advice — it doesn’t replace your surgeon or physical therapist. When something feels wrong, or you’re just not sure, call your care team. That is exactly what they are there for.
You arrived with an idea of how this would go. It came from somewhere real — a friend’s recovery, an injury you had before, something you read, something a chatbot told you at midnight. Then someone in a clinic proposes a different plan, and nobody quite says out loud that the two do not match.
That gap is normal and it is worth talking about rather than swallowing. Here are three of the most common versions, what the research actually says about each, and where each one stops being certain.
A completely reasonable thing to want. One appointment, one needle, and the pain quiets down. In a trial that randomised 156 adults with knee osteoarthritis to either a course of physical therapy or a steroid injection and followed them a year, the therapy group ended up with more quality of life, at nearly the same knee-related cost. Most people in the injection group needed more than one injection. The only knee surgeries that year were in the injection group.
Where it stops: one year, one military health system with no copays, and total medical costs were actually higher in the therapy group. It is one trial, not a rule — and injections are a real option, especially to get you comfortable enough to do the work.
Read the study, with its limits →Waiting is the most human plan there is, and life is genuinely busy. In a study of 67,245 adults who were referred to physical therapy after a knee osteoarthritis diagnosis, the longer the wait before starting, the higher the chance of being on opioids a year later — and it went up in steps, not all at once. Starting within the first month was the group that did best.
Where it stops: this is insurance-claims data, not a trial, and people who wait longer often have different knees and different lives than people who start early. That difference could explain part of it. Nobody in that study was told when to start.
Read the study, with its limits →This one usually needs no correction at all, just time. Hoping for a fast, complete recovery does not hurt anything, and it is often part of what gets people through the first hard fortnight. What tends to happen is that the expectation updates itself as the early wins arrive and the picture gets clearer.
The one thing worth knowing early: you will feel better before you are better. Those are two different dates, and the gap between them is where most setbacks happen.
Why those are two different dates →Four questions that turn a disagreement into a plan
None of this is about being talked out of what you want. A clinician working this way is trying to understand what is driving the expectation before responding to it — and where the evidence is genuinely uncertain, the honest move is a time-limited plan you both agree to review, not a verdict. If you raise it and the conversation shuts down instead of opening up, that is worth noticing too.
This section follows a framework published for physiotherapists in 2026 for navigating exactly this tension — expectations that align with the evidence, expectations that go beyond it without causing harm, and expectations that conflict with it. General education, not medical advice, and no substitute for your own surgeon or therapist.
Honest answers based on what typically happens — not what the worst-case scenario looks like.
Will I need a walker or cane?
Most patients go home with a walker after knee or hip replacement. Typically you transition to a cane by week 2–3, and most patients are walking without either by week 4–6. Shoulder patients are not affected in the legs at all.
When can I drive again?
For a right knee replacement: typically 4–6 weeks (you must be off narcotic pain medication and able to do emergency braking). Left knee or hip: often 2–3 weeks if you drive an automatic. Your surgeon clears you at your follow-up visit.
How much pain should I expect?
Pain peaks on day 2–3, then improves steadily. Most patients describe it as manageable — not the severe arthritic pain they lived with before. Modern nerve blocks and multimodal pain protocols have changed the experience significantly over the past decade.
Will I need someone at home with me?
For the first 24–48 hours, yes. After that, most patients are safely independent with appropriate home setup (grab bars, clear pathways). Many patients live alone and do fine after the first day or two.
When can I shower?
Most surgeons allow showering 48–72 hours after surgery once the surgical dressing is changed. No submerging the incision (bath, pool, hot tub) until the wound is fully healed — typically 4–6 weeks. Your surgeon gives specific instructions at discharge.
How do I know if something is wrong?
Most complications are rare. CMS data show 90-day readmission after total knee replacement is roughly 5–7% — meaning more than 9 in 10 patients recover without a hospital return. Call your surgeon's office for: a fever higher than 101°F (38.3°C), or the number your team gives you, increasing redness or drainage at the incision, sudden calf swelling or pain (possible DVT), or pain that gets significantly worse after initially improving. When in doubt, call — that is what the on-call line is for.
Will the replacement feel normal?
Most patients say their hip replacement feels very natural within a few months. Knee replacements often feel more artificial at first — some patients notice a slight clicking or awareness of the hardware. Most adapt within 3–6 months. Shoulder replacement outcomes depend heavily on the type of procedure and rotator cuff health.
What is the most important thing I can do for recovery?
Do your exercises. Every day. Even when you are tired. The patients who recover fastest are the ones who do the PT work consistently. The hardware does not heal itself — the surrounding muscles do, and they need the stimulus.
Most patients leave appointments wishing they had asked more. These are the questions orthopedic surgeons hear least often — and that make the biggest practical difference. Tap a phase to expand.
Want only the questions still open for you? The Know before you go worksheet takes about five minutes: mark what your team has already told you and what is ready at home, and print the rest as your list.
These are general questions drawn from orthopedic patient education literature. They do not replace your surgeon's specific instructions. Always follow your care team's guidance.
Three categories of intervention have the strongest evidence for shortening recovery and reducing post-op problems. These are not optional extras — they are the core of modern surgical care. Educational information only; follow your surgeon's specific plan.
A 2024 systematic review of four trials of structured pre-op exercise with lifestyle changes before knee replacement saw a positive trend, but better pain and function showed up in only one study and shorter stays in only one. The authors call the evidence limited. Ask your surgeon or PT whether pre-hab is right for you.
Enhanced Recovery After Surgery (ERAS) is a standardized perioperative pathway — multimodal pain management, early mobilization the day of surgery, reduced fasting, and avoiding routine drains and catheters — that has been shown to reduce average hospital stay after joint replacement from 3–5 days to 1–2 days, and to cut major complications.
Home exercise adherence — doing the prescribed PT exercises between clinic visits — is the variable you control. Estimates of nonadherence in rehabilitation run as high as 50% (Argent et al., 2018), and it is invisible to your care team unless it is documented.
In a randomized trial of 156 adults with knee osteoarthritis, a course of physical therapy gained more quality of life over a year than a steroid injection, at nearly the same knee-related cost. Most injection patients needed more than one injection (mean 2.6), and the only knee surgeries that year were in the injection group.

JointCoach uses your phone camera to measure your range of motion and count reps at home. It keeps a one-page summary on your phone that you can show or print for your surgeon and PT. Nothing is sent to your care team automatically. If your practice provides remote monitoring, Medicare covers it under standard Part B cost-sharing, and supplemental plans often cover it in full.
You'll also be asked to fill out a short survey — before surgery, and again about a year later. Please answer both, especially the one-year one. It's a few minutes, and it's the honest answer to the only question that matters: did the surgery actually make your knee or hip better? It's also, now, how Medicare measures your surgeon's results — so when you skip it, your own good outcome simply doesn't get counted. The one-year check-in is the easiest one to blow off and the most important one to finish.
