How Pre-Operative Physiotherapy Improves Surgical Outcomes

Preparing for surgery is about more than just scheduling a procedure and waiting for your

operation date. What you do before surgery — especially when it comes to your physical readiness — can profoundly influence how well you function afterward. This is where pre-operative physiotherapy, also called prehabilitation, comes in.

A recent research article published in JAMA Network Open looked at randomized clinical trials involving more than 3,500 patients to determine whether prehabilitation offers measurable benefits for people undergoing orthopedic surgeries. The findings reinforce a simple but powerful idea: the stronger and more prepared your body is going into surgery, the better equipped it is to recover afterward.

At Physical Edge Physiotherapy, we regularly integrate pre-op physiotherapy into care plans for patients preparing for ACL reconstruction, joint replacements, back surgery, rotator cuff repair, and other orthopedic procedures — and this research helps explain why that strategy works.

What the Study Examined

The review compared people who participated in prehabilitation programs (which typically included exercise, strength training, and functional movement training) with people who received usual care (no structured pre-op program).

The authors examined key outcomes such as:

• Function (ability to perform daily tasks and movements)

• Muscle strength

• Health-related quality of life

• Back pain

• Functional performance tests like walking tests and mobility measures

Main Findings: Prehab Helps Before and After Surgery

1. Better Function Before Surgery

People preparing for surgery with structured physiotherapy showed significant improvements in function compared with those who did not. This was especially true for:

• Total Knee Replacement — Improved overall function and stronger knee flexor muscles.

• Total Hip Replacement — Increased muscle strength and improved health-related quality of life before surgery.

• Lumbar (Lower Back) Surgery— Less back pain and better quality of life before the operation. In fact, the evidence for back pain reduction was rated high-certainty — meaning the research strongly supports that prehab helps reduce pain before surgery.

  
  

2. Stronger Muscles Going Into Surgery

Prehabilitation was consistently associated with improved muscle strength before surgery — especially around key muscle groups like knee flexors and hip abductors (important for stability and movement after joint replacements).

Stronger muscles mean your body starts from a better baseline, making it easier to handle the stresses of surgery and begin postoperative rehabilitation sooner and more effectively.

3. Better Quality of Life Before Surgery

People in prehab programs reported better health-related quality of life (HRQOL) — meaning they felt physically and mentally better equipped for the challenges ahead. This was seen in patients preparing for hip replacements and lumbar surgeries.

Preparing your body ahead of time isn’t just physical — it boosts confidence, reduces anxiety around movement, and often leads to improved readiness for life after surgery.

4. Postoperative Benefits — Especially Early on

Although the quality of long-term evidence was mixed, there was moderate-certainty evidence that prehabilitation:

• Improved function at 6 weeks after total knee replacement

• Improved function at 6 months after lumbar surgery 

These findings suggest that the benefits of prehab continue into the recovery period — particularly during the early and medium stages of postoperative healing, when strength and mobility gains are crucial.

Why Pre-Op Physiotherapy Works

So how does prehabilitation help? The research points to several mechanisms:

Builds Physical Resilience

Prehabilitation targets muscle strength, joint mobility, and cardiovascular endurance — all of which help your body cope with the physiological stress of surgery and immobility during recovery.

Improves Functional Movement

When you enter surgery with better balance, coordination, and movement patterns, you’re more likely to fall into effective recovery sooner — because your body already knows how to move well.

Boosts Confidence

Knowing you’ve actively prepared builds confidence — and confidence supports better adherence to postoperative therapy and return-to-activity goals.

What This Means for You

Whether you’re preparing for a:

• Total knee replacement

• ACL reconstruction

• Hip replacement

• Shoulder replacement

• Lumbar spine surgery

• Rotator Cuff Repair

• Or another orthopedic procedure,

Pre-operative physiotherapy gives you a head start on recovery. The evidence shows that people who take the time to strengthen, stretch, and move before surgery generally:

✔ Have better physical function before surgery

✔ Enter surgery stronger and more confident

✔ Recover movement and strength more effectively afterward

✔ Report better quality of life leading up to and following surgery

At Physical Edge Physiotherapy, our team specializes in developing personalized prehabilitation plans tailored to your surgical timeline, fitness level, and recovery goals. Our approach focuses on building strength, reducing pain, and improving movement quality before your procedure — so you’re ready to recover faster and more confidently.
