Physiotherapy before surgery: why prehab changes your outcome

In Indian orthopaedic practice, the conversation before joint surgery typically covers the procedure itself, the anaesthesia plan, pre-operative blood tests, and what to expect on the day. What it almost never includes is a structured exercise programme to prepare your body for surgery.

This is a significant missed opportunity. Research consistently shows that patients who complete a prehabilitation (prehab) programme before joint surgery have shorter hospital stays, less post-operative pain, faster return to function, fewer complications, and better long-term outcomes compared to those who go into surgery without preparation.

The reason is straightforward: surgery is a physical stress. The stronger and fitter you are going into it, the better your body handles that stress and recovers from it. Going into a knee replacement with weak quadriceps is like running a marathon without training. You will finish, but it will be harder and take longer to recover.

Multiple clinical trials have studied prehab before joint replacement and other orthopaedic surgeries. The results are consistent and significant.

Before knee replacement: patients who completed 4 to 6 weeks of prehab had 30% faster recovery of quadriceps strength, walked independently sooner, needed less post-operative physiotherapy, and reported better satisfaction at 3 months. Some studies show reduced hospital stay by 1 to 2 days.

Before hip replacement: prehab patients showed faster return to walking, stair climbing, and independent daily activities. They also had lower rates of post-operative complications like deep vein thrombosis, partly because they entered surgery in better cardiovascular condition.

Before ACL reconstruction: this is where prehab has the strongest evidence. Patients who restored full knee range of motion and at least 80% quadriceps strength before surgery had significantly better outcomes at 6 and 12 months post-surgery. Some surgeons now delay ACL reconstruction until the patient has completed prehab targets.

Prehab is not just "do some exercises before surgery." It is a structured, progressive programme targeting the specific muscles and functions that will be affected by your surgery. For knee replacement prehab, the focus is on quadriceps strengthening (the most important predictor of knee replacement recovery), hamstring and hip muscle strengthening, range-of-motion exercises to maximize the flexibility you bring into surgery, gait training and balance exercises, and cardiovascular fitness (even simple walking programmes improve surgical tolerance).

For hip replacement prehab, the programme emphasizes hip abductor and extensor strengthening, core stability, balance training, and practising the post-operative movement precautions (like the specific ways you will need to get in and out of bed and chairs after surgery).

For ACL reconstruction prehab, the goals are specific: restore full knee extension (straightening), minimize swelling, regain at least 80% quadriceps strength compared to the other leg, and establish good neuromuscular control. Meeting these targets before surgery is associated with dramatically better outcomes.

Prehab is standard practice in countries like the UK (where it is part of NHS joint replacement pathways), Australia, and Scandinavian countries. In India, it is rarely discussed for several reasons.

Time pressure: most Indian orthopaedic consultations are brief, and discussing a 4-week exercise programme does not fit the consultation format. Awareness gap: prehab evidence has grown significantly in the last decade, and not all surgeons are up to date. Pathway design: Indian hospital systems are set up for pre-surgical medical clearance (blood tests, ECG, anaesthesia review) but not for pre-surgical physiotherapy. Revenue model: extending the time to surgery by 4 weeks to do prehab is not in the financial interest of hospitals.

None of this means your surgeon does not want the best outcome for you. Most surgeons, when asked, will support prehab. They simply may not think to recommend it because it is not part of the standard Indian surgical pathway.

If you have a surgery date scheduled, you can start prehab independently. The ideal window is 2 to 6 weeks before surgery, but even 2 weeks of focused preparation is beneficial. Here is how to get started.

Talk to your surgeon: let them know you want to do pre-surgical physiotherapy. Ask if there are any specific exercises they recommend or any restrictions you should follow. Most surgeons will be supportive.

Start a structured programme: Nuprana offers online prehab programmes for patients preparing for knee replacement, hip replacement, or ACL reconstruction. Your programme includes an initial assessment, a progressive exercise plan tailored to your surgery type, regular online sessions with a physiotherapist to monitor progress and adjust exercises, and education about what to expect after surgery.

Online prehab is particularly practical because you are exercising at home, which is where you will be doing your post-operative rehabilitation too. Your physiotherapist can assess your home environment, identify potential obstacles (stairs, bathroom setup, furniture heights), and help you prepare your space for recovery.

One of the less obvious benefits of prehab is that it familiarizes you with the exercises and the physiotherapist relationship before surgery. After surgery, you will be in pain, on medication, and mentally foggy from anaesthesia. This is not the ideal time to learn new exercises for the first time.

Patients who have done prehab already know the exercises, know what to expect from physiotherapy, and have an established relationship with their physiotherapist. This makes the post-operative rehabilitation process smoother, faster, and less stressful.

If you are having surgery with Nuprana's online physiotherapy support, your prehab physiotherapist continues as your post-operative rehabilitation physiotherapist. This continuity means they already understand your baseline, your goals, and your home environment, and can design post-operative progression based on where you were before surgery.
