What knee replacement involves
Knee replacement resurfaces the damaged ends of the femur and tibia with metal components separated by a plastic bearing. A partial replacement treats one compartment only and preserves more of the natural knee; a total replacement addresses the whole joint.
Knee replacement is more demanding to rehabilitate than hip replacement. Range of motion achieved in the first six weeks strongly predicts the final result, which makes the physiotherapy plan the most important part of the package.
Who it is for
For advanced arthritis with pain and stiffness that limit walking, sleep and daily activity after conservative treatment has failed.
- Severe compartmental or global knee arthritis
- Pain at rest or at night
- Failed physiotherapy, injections and weight management
- Committed to intensive early rehabilitation
- ✕Active infection
- ✕Poor quadriceps function that will not support rehabilitation
- ✕Unrealistic expectation of a fully "normal" knee
- ✕Unmanaged obesity or uncontrolled diabetes
How the procedure works
Assessment
Weight-bearing X-rays to confirm which compartments are affected and whether partial replacement is possible.
Surgery
Damaged surfaces removed and components cemented or press-fitted. Typically 90 minutes to two hours.
Immediate mobilisation
Standing and bending usually starts on the day of surgery or the day after.
Range-of-motion work
Daily physiotherapy targeting flexion. Falling behind here is difficult to recover.
Strengthening
Progressive quadriceps and hamstring work over three to six months.
Risks and complications
Alongside the clot and infection risks common to joint replacement, knee replacement carries a specific risk of stiffness. If flexion targets are not met early, manipulation under anaesthetic may be needed. Persistent anterior knee pain affects a minority of patients even with a technically perfect implant.
- !Stiffness requiring manipulation under anaesthetic
- !Deep vein thrombosis, raised by long-haul flying
- !Deep infection, roughly 1%
- !Persistent anterior knee pain
- !Ongoing numbness lateral to the scar, common and usually permanent
Cost by destination
Indicative pricing for knee replacement runs from £7,000–£12,000 depending on destination, clinic and case complexity. Figures below are indicative estimates for comparison and have not yet been independently verified. They are not quotes, and they exclude flights, accommodation and any aftercare once you are home.
Always ask a clinic to itemise in writing what a quoted price includes and, more importantly, what it excludes. A quote that cannot survive that question is not a quote.
Recovery timeline
Days 1–3
Mobilising with a frame. Flexion exercises begin immediately and are uncomfortable.
Days 4–7
Inpatient physiotherapy. Target of roughly 90 degrees flexion before discharge.
Weeks 2–6
The critical window. Daily physiotherapy; most patients reach 110–120 degrees.
Weeks 6–12
Return to driving and desk work. Swelling continues to fluctuate.
Months 3–12
Strength and confidence build. Final outcome typically at nine to twelve months.
Choosing a clinic
Ask what the package includes in supervised physiotherapy sessions, not just inpatient days. Ask how many knee replacements the surgeon performs annually, and what the plan is if flexion targets are missed. Confirm the daily rate for extra inpatient days before you travel.
Frequently asked questions
How long must I stay abroad?
Plan three weeks: five to seven days inpatient, then two weeks of outpatient physiotherapy and wound checks before a fitness-to-fly assessment.
Partial or total replacement?
A partial preserves more natural knee and recovers faster, but only suits single-compartment disease and has a higher revision rate. Weight-bearing X-rays decide it.
Will my knee feel normal?
It should be substantially less painful, but most patients describe it as different from a natural knee. Kneeling is often uncomfortable permanently.
What if I do not get my range of motion back?
If flexion stalls below about 90 degrees at six weeks, manipulation under anaesthetic may be offered — and that is far easier arranged where you were operated on.
When can I fly home?
Two to three weeks, with clot prophylaxis and formal clearance. Budget for extra legroom; a long flight in a standard seat this soon after knee surgery is genuinely difficult.
