What hip replacement rehabilitation is
A total hip replacement replaces the ball at the top of the thigh bone and resurfaces the socket, most often with a metal or ceramic head against a polyethylene liner. Outcomes are excellent, with roughly 95 per cent of implants surviving to ten years and around 85 per cent to twenty.
It is generally an easier recovery than knee replacement. Pain relief is often immediate and dramatic, and the main rehabilitation work is restoring the strength and walking pattern lost during the years of arthritis before the operation.
Movement precautions vary by surgical approach. A posterior approach usually comes with restrictions on bending past 90 degrees, crossing the legs and rotating inward, for six to twelve weeks. An anterior approach often has few or no restrictions. Follow the instructions from your own surgical team.
What causes it
The limiting factor in most hip replacement recoveries is not the joint. It is the abductor weakness and altered walking pattern that built up over the years of arthritis before surgery, and those do not correct themselves when the joint is replaced.
This is why so many people walk comfortably at six weeks with a limp they still have at six months. The limp is a habit and a strength deficit, and both respond to deliberate work.
What determines the result
- Hip abductor strength, which is typically well below normal before surgery and stays there without training
- Gait retraining, since limping patterns outlast the reason for them
- Pre-operative strength and conditioning, which predict the post-operative result
- Adherence to the precautions that apply to your surgical approach
- Continuing strength work past the three-month mark
- General activity level, since walking distance builds back quickly with structure
The Trendelenburg sign is the thing to watch: standing on the operated leg, does the opposite side of the pelvis drop? That indicates abductor weakness, and it is present in a large proportion of people months after surgery who consider themselves recovered. Correcting it is what removes the residual limp, and it responds well to targeted work even a year or more after the operation.
What the evidence says
Progressive resistance training after hip replacement improves strength, gait and function beyond what usual care achieves, with benefits demonstrated when started in the early post-operative period and continued for several months.
Prehabilitation improves early function and reduces length of stay, with the effect strongest in people who were weakest before surgery.
Enhanced recovery pathways have shortened hospital stays substantially, with many people now discharged within one to three days and mobilising on the day of surgery.
Evidence for the strict posterior precautions has been questioned, with several studies finding no increase in dislocation when they are relaxed with modern implants and techniques. Practice varies between surgeons, and following your own team's guidance is the right approach.
Abductor strength deficits commonly persist at twelve months without specific training, which is the strongest argument for continuing rehab past the point of comfort.
Recovery timeline
Typical milestones: walking with aids on the day of surgery or the day after, off crutches somewhere between two and six weeks, driving at around four to six weeks, and a return to most daily activity by six to twelve weeks.
Strength continues improving for a year. Many people plateau at three months simply because the rehab stopped there, and pick up substantial further gains when they resume structured work.
| Stage | ✓ Do this | ✗ Avoid this |
|---|---|---|
| Weeks 0–2 | Walk regularly in short bouts. Ankle pumps, glute setting, assisted hip movement within your precautions. | Sitting in low chairs if you have posterior precautions |
| Weeks 2–6 | Progress walking distance. Begin standing abduction and extension work. Wean off aids as balance allows. | Abandoning the crutches before the limp has gone |
| Weeks 6–12 | Progressive strength: step-ups, sit-to-stand, resisted abduction, balance work. Stationary bike. | Stopping because walking feels normal |
| 3–12 months | Continue strengthening. Return to swimming, cycling, golf, hill walking, doubles tennis. | Accepting a residual limp as permanent |
How we treat it at Kingsway
Post-operative rehab here
We work within the precautions your surgical team has set, and focus on the abductor strength and gait work that a standard pathway often leaves unfinished.
- Gait assessment, including a Trendelenburg test to quantify abductor weakness
- Hip range measured within your precautions and tracked over time
- Manual lymphatic drainage and soft tissue work for post-operative swelling
- Soft tissue release for the lumbar spine and opposite hip, which have usually been compensating for years
- Progressive abductor and extensor strength programme
- Gait retraining to remove the limp once the strength is there to support it
Rehab typically begins once your surgical team is happy for hands-on work, often around two to six weeks. A course through to three months and then reviews out to a year matches the strength curve. Sessions can be spaced widely, since the programme between visits does the work.
When to get it checked
Follow your surgical team's schedule. Book additional rehab if you still have a limp after the crutches have gone, if the leg feels weak going up stairs, or if you have reached three months and want to get back to hill walking, golf or cycling properly.
See a doctor or go to A&E if
- Calf pain, swelling, warmth or redness, which needs a blood clot excluded urgently
- Fever, wound discharge, spreading redness or increasing wound pain
- Sudden severe hip or groin pain with an inability to weight-bear, which can indicate dislocation
- A leg that suddenly appears shorter, or turns inward or outward at rest
- Chest pain or shortness of breath, which requires emergency assessment
Common questions
Which precautions apply to me?
It depends on the surgical approach. Posterior approaches usually restrict bending past 90 degrees, crossing the legs, and inward rotation for six to twelve weeks. Anterior approaches often carry few or no restrictions.
Your surgical team's instructions are the authority here, and they take precedence over any general guidance.
When can I sleep on my side?
Most teams allow side-lying on the non-operated side with a pillow between the knees from around two to six weeks, and on the operated side somewhat later once comfort allows.
Check the specific timing with your team, since it varies with approach.
Why do I still limp?
Almost always because of hip abductor weakness that predates the surgery, combined with a walking habit formed over the years of arthritis.
It responds well to targeted abductor strengthening and gait retraining, even a year or more after the operation.
What activities should I avoid long-term?
Running, jumping and high-impact sport are generally discouraged because they shorten implant life. Most teams are happy with walking, hiking, cycling, swimming, golf and doubles racket sports.
Ask your surgeon about anything specific you want to return to, since advice varies with implant type and your age.
