Pre-Surgery
ACL Rehab.
The stronger you go in, the faster you come out.
Pre-surgery ACL rehabilitation — prehab — is one of the single strongest predictors of post-operative outcomes. Athletes who complete structured prehab before ACL reconstruction consistently return to sport faster, achieve higher strength symmetry, and have lower re-injury rates than those who don't.

Why Prehab?
Why it matters
Prehab isn't optional.
It's your head start.
Surgery repairs the ligament. Prehab builds the body around it. The research is unambiguous — pre-operative strength is one of the most important predictors of post-operative recovery, strength symmetry, and return-to-sport outcomes.
Pre-operative quad strength is one of the strongest independent predictors of post-op outcomes. Every percentage point of quad strength you enter surgery with means more to recover from a higher baseline on the other side.
Entering surgery with full range of motion and minimal swelling dramatically reduces the risk of post-operative complications including arthrofibrosis — one of the most frustrating ACL recovery setbacks.
The nervous system needs to relearn how to activate muscles around the knee after injury. Prehab starts that relearning before surgery, so post-op rehab begins from a better neuromuscular baseline.
Athletes who complete prehab enter surgery with greater confidence, lower fear of movement, and better understanding of the rehab process ahead. Psychological readiness is a genuine predictor of ACL rehab outcomes.
The evidence
What the research shows.
The evidence base for prehab is strong and consistent across multiple high-quality studies.
Athletes who complete prehab are up to 4 times more likely to return to their pre-injury sport level compared to those who proceed directly to surgery without preparation.
Eitzen et al., British Journal of Sports Medicine
Normalising quadriceps strength before surgery (achieving greater than 90% limb symmetry index pre-operatively) is associated with an 84% rate of return to pre-injury sport.
Kyritsis et al., BJSM 2016
As little as 5-6 weeks of structured prehab before ACL reconstruction produces significant improvements in strength, function, and patient-reported outcomes — with benefits persisting well into the post-operative period.

What we do
What your prehab
program looks like.
Every prehab program at SportsFit starts with a comprehensive assessment. We test where you are, identify the gaps, and build a structured program to close them before your surgery date.
Initial Assessment
Force plate testing to baseline your limb symmetry. Range of motion assessment. Strength testing — quads, hamstrings, hip abductors. Movement quality screening. We establish exactly where you are before building the program.
Swelling & ROM Management
Manual therapy, compression, and specific exercises to reduce effusion and restore full range of motion. Entering surgery with a swollen, stiff knee significantly increases post-operative complication risk.
Strength Loading
Progressive quad, hamstring, glute, and calf loading. Tailored to your baseline strength, your surgery date, and what your knee will tolerate. Blood flow restriction training is often used here to build quad strength with minimal joint load.
Neuromuscular Retraining
Single-leg balance, proprioception work, and movement pattern retraining. The ACL is a major proprioceptive organ — retraining the sensory system before surgery gives post-op rehab a significant head start.
Pre-Surgery Re-Testing
A final force plate assessment in the week before surgery. We document your pre-operative baseline so post-operative strength targets are set against real data, not population norms.
Common questions
FAQ — ACL Prehab.
How long should I do prehab before surgery?
The research suggests 5-6 weeks minimum to see meaningful strength and functional gains. Ideally 6-12 weeks if your surgery timeline allows it. Even 2-3 weeks of structured prehab is better than none. We'll work with whatever your surgeon's timeline allows.
Do I need a referral?
No referral needed. You can book directly online. If your surgeon or GP has referred you, bring any imaging or reports to your first appointment.
Can I do prehab if my knee is still very swollen and painful?
Yes — and this is actually where prehab is most important. Significant swelling and pain before surgery often means entering surgery in poor condition. We'll manage the swelling, restore range, and work around what your knee will tolerate. You don't need to be pain-free to benefit from prehab.
Will prehab help even if I'm having surgery soon?
Yes. Even 2-3 weeks of prehab can meaningfully improve your pre-operative quad strength and reduce swelling. The research shows benefit even with short prehab windows.
Can I continue prehab with you post-surgery?
Absolutely. We encourage it — continuity of care through the full rehab journey is associated with better outcomes. We'll transition seamlessly from prehab to post-op rehab with all your baseline data already documented.
