Knee Replacement Recovery Timeline — Total (TKR) and Partial (UKR)
A practical, criteria-based guide to recovery after total knee replacement (TKR) and partial knee replacement (UKR). Timings vary by patient; your plan is personalised in clinic.
Phase 0 — Prehab (2–6 weeks before surgery)
Goals
- Optimise range of motion (aim for full extension; flexion as comfortable)
- Quad and hip strength (straight-leg raises, chair stands)
- Practice crutches and stair technique
- Education: pain control, swelling management, sleep, home set-up (chairs, ice, safe walkways)
Surgery Day (Day 0)
- Spinal or general anaesthetic; enhanced recovery pathway
- Walk the same day or next morning with physiotherapy (frame or crutches)
- Start circulation exercises, quad sets, ankle pumps
- Pain, nausea, and DVT (blood clot) prevention protocols initiated
Week 1 — Settle & Mobilise
Milestones
- Safe transfers, short indoor walks with walking aids (frame or crutches)
- Climb a few stairs with supervision (up with the good, down with the operated + rail)
- Wound clean/dry; swelling managed with elevation and icing
- ROM goals: extension to 0°, flexion 70–90° (TKR); 80–100° (UKR)
Focus
- 5–6 short walks daily; heel slides; gentle quads/hamstring activation
- Regular pain meds as prescribed; avoid prolonged sitting
Weeks 2–3 — Confidence & Control
Milestones
- Independent indoor mobility; progressing outdoor walks
- ROM: 0–90°+ (TKR) and 0–100°+ (UKR)
- Reducing swelling; better sleep routine
- Wound review around 10–14 days, either at Circle Reading Hospital or with your GP practice — this is arranged to suit you and will be confirmed before you leave hospital. Mr Nahas uses dissolving stitches, so there are usually none to remove
Focus
- Stationary bike (small arc to full revolutions as tolerated)
- Gentle closed-chain strength (sit-to-stand, mini-squats to chair height)
- Gait pattern: longer steps, heel-to-toe
Weeks 4–6 — Strength & Function
Milestones
- Wean from sticks as gait normalises
- ROM: 0–100–110° (TKR) and 0–110–120° (UKR)
- 10–20 minutes outdoor walking most days
Focus
- Progressive strengthening (leg press light range, bridges, hip hinges)
- Balance: double → single-leg stance (kitchen worktop support)
- Light household tasks; maintain icing post-exercise if swelling rises
Typical returns
- Driving: around 6 weeks, once you can perform an emergency stop safely and are off strong painkillers. This also depends on which leg was operated on and whether you drive a manual — see Driving after knee surgery. Mr Nahas will advise; DVLA guidance applies
- Office work: 2–4 weeks for UKR; 4–6 weeks for TKR (role-dependent)
Weeks 6–12 — Endurance & Everyday Life
Milestones
- Community walking without aids; stairs reciprocally if strength allows
- ROM trends to 110–120°+ (varies)
- Reduced swelling after activity; sleep largely restored
Focus
- Strength progression (step-ups/downs, split-squat to tolerance)
- Static bike, cross-trainer, pool once wound fully healed
- Gait quality and endurance blocks (interval walking)
Typical returns
- Manual/standing work: commonly 6–12 weeks+ depending on demands
- Low-impact sport: cycling, swimming, gentle golf range/putting — around 8–12 weeks after UKR and 10–12 weeks after TKR, if comfortable and with clearance from Mr Nahas or your physiotherapist
Months 3–6 — Return to Activities
Milestones
- Strong, symmetrical walking pattern
- Functional tasks without support; improved confidence on uneven ground
- Swelling minimal and settles quickly after exercise
Focus
- Power and endurance (step-downs, controlled lunges within comfort, resisted hip work)
- Sport-specific re-introduction: longer golf sessions, outdoor cycling, swimming, gentle doubles tennis (non-impact focus)
Typical expectations
Many patients feel "normalising" function by 3–6 months, with continued gains up to 12 months (sometimes 18) after TKR.
Activity Guidance (general)
- Recommended: walking, cycling, swimming, golf, doubles tennis, low-impact gym work
- Approach cautiously: hiking steep/uneven terrain early on, heavy lifting
- Usually avoid: repetitive high-impact running/jumping and contact sports after TKR/UKR
Pain, Swelling, and Sleep
- Use prescribed analgesia regularly early on; taper as able
- Ice 15–20 minutes, 3–5 times daily (more on exercise days). Always wrap the ice pack in a damp tea towel — never put ice directly on the skin, as it can cause an ice burn
- Elevate when resting; short frequent walks beat long inactive periods
- Sleep improves as swelling and night pain settle; a pillow between ankles (not under the knee) can aid comfort
Kneeling
Sensitivity over the front of the knee is common. Some patients kneel comfortably by 3–6 months; others prefer a cushion or avoid kneeling. This varies and is not harmful if comfortable.
Red Flags — Seek Advice Urgently
- Fever, increasing redness, heat, or discharge from the wound
- Calf pain/swelling, chest pain, or breathlessness (possible DVT/PE)
- Sudden, severe increase in pain or loss of function
- Unusual clicking with sharp pain, or new giving-way
Contact the clinic or appropriate urgent care service if these occur.
FAQs
Some swelling is normal for weeks to months, gradually reducing. It often rises on busier days and settles with rest, ice, and elevation.
Functional goals are full extension (0°) and flexion sufficient for stairs and sitting (110–120°+ for many). Individual variation is expected.
Often yes — many patients progress mobility and function a little sooner than TKR, but both continue to improve for months.
Mr Nahas does not advise flying for 6 weeks after surgery.
