Prehab before joint surgery

Prehabilitation - structured exercise and optimisation before joint surgery - improves fitness going into the operation and speeds recovery afterwards.

Key points

The essentials at a glance.

What to look out for, who treats it, and what usually happens next.

  • Stronger going in means faster recovery coming out

  • Quadriceps and hip strength predict early function after knee and hip replacement

  • Weight, smoking, diabetes control and anaemia are all worth optimising

  • Even four to six weeks of targeted exercise makes a measurable difference

  • Prehab also teaches the exercises you will use after surgery

Understanding it

About Prehab before joint surgery.

The weeks before a joint replacement are an opportunity, not a waiting room. Building strength around the joint, improving cardiovascular fitness, correcting anaemia, optimising diabetes control and stopping smoking each independently improve surgical outcomes - and learning the post-operative exercises beforehand makes the first weeks after surgery far smoother.

A prehab programme is typically physiotherapist-led and tailored to what the painful joint allows, often using cycling, pool work and resistance training. Discuss it as soon as surgery is planned: the longer the runway, the greater the benefit. In the UK you can start with your GP: on the NHS, a routine referral to a specialist clinic often means waiting 20–45 weeks or more to be seen, while a private consultant will typically see you within around two weeks, with any tests arranged soon after.

Frequently asked

Common questions about Prehab before joint surgery.

Quick, plain-English answers to what people ask us most.

  • What is prehabilitation (prehab) before joint surgery?

    Prehabilitation, or prehab, is a structured programme of exercise and preparation undertaken before joint surgery, such as hip or knee replacement, aimed at optimising strength, fitness, and overall health to improve recovery afterwards.

  • Why is prehab recommended before joint surgery?

    Entering surgery with better muscle strength, cardiovascular fitness, and overall physical condition is associated with faster and smoother recovery, reduced complication rates, and often better long-term outcomes after joint replacement.

  • What does a prehab programme typically involve?

    It usually includes targeted strengthening exercises for the muscles around the affected joint, general cardiovascular fitness work, and sometimes attention to nutrition, weight management, and smoking cessation if relevant.

  • How long before surgery should I start prehab?

    Starting six to twelve weeks before surgery, where possible, allows enough time to build meaningful improvements in strength and fitness, though even a shorter period of focused preparation can still be beneficial.

  • Does prehab really improve outcomes after joint replacement?

    Yes, a growing body of evidence supports that patients who undertake structured prehabilitation often have faster early recovery and, in some studies, better overall functional outcomes after joint replacement surgery.

  • Can I do prehab if I have significant pain in the joint?

    Yes, a physiotherapist can tailor a prehab programme to work within your pain limits, often focusing on strengthening surrounding muscles and general fitness in ways that don't excessively stress the painful joint itself.

  • Prehab vs post-surgical rehabilitation — what's the difference?

    Prehab takes place before surgery to optimise your condition beforehand, while post-surgical rehabilitation happens afterwards to restore function and mobility as you recover; both are important and complementary parts of the overall joint replacement journey.

  • Is prehab suitable for everyone having joint surgery?

    Most people can benefit from some form of prehab, though the specific programme is tailored to individual fitness levels, other health conditions, and the severity of joint symptoms, so an assessment by a physiotherapist is recommended.

  • Does prehab reduce hospital stay after surgery?

    Some evidence suggests that better pre-surgical fitness and strength can contribute to a shorter hospital stay and quicker return to independent function, though this varies between individuals and types of surgery.

  • When should I start prehab, and how quickly can I access this privately?

    Ideally start prehab as soon as joint replacement surgery is being planned. Private physiotherapy for a prehab programme is typically available within about two weeks, considerably faster than some NHS physiotherapy waiting lists, which is helpful given the time-limited window before surgery.
