Physiotherapy after an injury or operation: how rehabilitation works

What it is

Rehabilitation after an injury or operation is a structured programme to restore movement, strength, balance and function so you can return to daily life, work and sport. The World Health Organization's rehabilitation fact sheet (22 April 2024) defines rehabilitation as a set of interventions designed to optimise functioning and reduce disability in people with health conditions, and gives examples that include exercise training to improve strength and balance and education on how to exercise safely. The WHO estimates that about 2.4 billion people worldwide live with a condition that may benefit from rehabilitation, and that in some low- and middle-income countries more than half do not receive the services they need.

Physiotherapists lead most musculoskeletal rehabilitation. The NHS physiotherapy page (reviewed 3 April 2025) describes the tools: exercise to improve joint movement and strengthen muscles, manual therapy, and adjuncts such as hydrotherapy. Post-surgical rehabilitation follows a protocol agreed with the surgeon, with timings that reflect how the repaired tissue heals.

Who it is for and when it is recommended

Rehabilitation is recommended after fractures once the bone is stable, after ligament and tendon injuries (such as ankle sprains, anterior cruciate ligament tears and rotator cuff problems), after joint replacement, spinal surgery, ligament reconstruction and many other operations, and after periods of immobilisation in a cast or sling. The WHO osteoarthritis fact sheet (14 July 2023) notes that joint replacement is most commonly performed at the hip and knee and that rehabilitation is part of management, and the NHS osteoarthritis page describes a structured exercise plan with a physiotherapist for more severe symptoms.

It is also valuable before planned surgery: building strength and learning the exercises beforehand, sometimes called prehabilitation, can make the early post-operative period easier. Ask your surgeon when rehabilitation should start; for many operations it begins within days.

What happens at the appointment

Assessment. The physiotherapist reviews the injury or operation notes and any restrictions set by the surgeon (for example, weight-bearing limits or a range of movement not to exceed). They measure joint range, swelling, strength, gait or arm function, and ask about pain, sleep, work demands and your goals.

Stages of a programme. Although timings differ by injury, most programmes move through similar phases:

1. Protection and early movement. Managing swelling and pain, gentle movement within safe limits, teaching you to use crutches, a sling or a brace correctly, and preventing stiffness in neighbouring joints.
2. Restoring range and basic strength. Progressive stretching and strengthening as the tissue tolerates it, and normalising walking or everyday arm use.
3. Building strength, balance and control. Heavier resistance, single-leg balance, functional tasks such as stairs, squatting, lifting or reaching overhead.
4. Return to activity. Sport- or job-specific training, impact and agility work for athletes, and criteria-based testing before returning to full activity.

Sessions typically last 30 to 60 minutes, with exercises to do at home in between. Manual therapy, taping or electrotherapy may be used as adjuncts, but exercise is the core.

How to prepare

Bring your operation notes or discharge summary, any protocol from the surgeon, imaging reports and your medicines list. Wear clothing that gives access to the area. Know your restrictions and tell the physiotherapist about them, including any that have changed since your last surgical review. Arrange transport if you cannot drive. Be clear about what you need to get back to, in what timeframe, because the programme will be built around that.

Afterwards and recovery

Rehabilitation is cumulative. The NHS stresses that doing the home exercises regularly matters for recovery, and most of the work happens between sessions. Expect muscle soreness for a day or two after harder sessions; increasing joint pain, swelling that does not settle overnight, redness, warmth, fever, calf pain or wound problems should be reported to the clinic or surgeon promptly. Progress is reviewed against measurable goals: degrees of movement, strength compared with the other side, distance walked, tasks achieved. Setbacks are common and are a reason to adjust the programme, not abandon it.

Risks and limitations (sourced)

Exercise within a supervised programme is low risk, and the main danger lies in doing too much too soon against the surgeon's restrictions, or too little for fear of harm. Manual therapy can cause short-term soreness. The limitation is that physiotherapy cannot change what has been repaired or how fast tissue heals; a tendon or bone has its own timetable, and claims of markedly faster recovery than the surgeon's protocol should be questioned. The WHO notes that in many settings the need for rehabilitation is largely unmet and that there are fewer than ten skilled rehabilitation practitioners per million people in some low- and middle-income countries, so access, not only quality, can shape outcomes. Recovery also depends on factors outside the clinic: age, general health, smoking, nutrition and the demands of your work.

What affects the cost

Fees vary by country, city and clinic, and some public systems include rehabilitation in the cost of surgery. Factors include:

• Number of sessions, which depends on the injury, surgery and your goals.
• Length of sessions and whether the first assessment is priced separately.
• One-to-one treatment versus supervised group classes.
• Hydrotherapy, gym-based rehabilitation or sports-specific facilities.
• Equipment such as braces, crutches or resistance bands.
• Home visits in the early period.
• Coverage by a national scheme or insurance, and whether a referral is required.

Ask for an estimate of the likely course and the price per session in writing. HealthNaro does not publish prices unless they come from a named, dated source.

Questions to ask the provider

1. Have you seen my surgical protocol or injury notes, and what restrictions apply right now?
2. What are the stages of my recovery, and roughly how long should each take?
3. What should I do at home, and how often?
4. What signs mean I should stop and contact you or the surgeon?
5. How will we measure progress, and what are the criteria for returning to work or sport?
6. How many sessions do you expect, and how will that change if I progress faster or slower?
7. What is your experience with this type of injury or operation?

How to find and check a provider

HealthNaro lists physiotherapy centres and physiotherapists with a verification label on every listing. Public listing means the details came from public sources and have not yet been checked. Contact verified means the provider has confirmed their phone number and email address. Reviewed by HealthNaro means our team has looked over the listing's details. Credentials verified means we have seen a licence or registration document. A label describes what has been checked; it is not a recommendation or a ranking, and HealthNaro does not endorse any provider.

Check the physiotherapist's registration with your national regulator or professional council and ask whether they communicate with your surgeon. You can browse providers under Physiotherapy and Sports Physiotherapy. If you would like help finding a suitable clinic, our consulting service is free: send a request through the inquiry form and we will come back to you with options. You choose whom to contact.
