Introduction

Facing anterior cruciate ligament (ACL) reconstruction surgery can feel overwhelming. It's natural to have concerns and questions, but understanding the process and preparing well can help ease your worries and support a smoother recovery. The ACL is a vital ligament that stabilises your knee, commonly injured during sports or sudden twists. When severely damaged, surgery to reconstruct the ACL is often necessary to restore knee function and stability.

Professor Paul Lee, a highly experienced orthopaedic surgeon, alongside the expert team at MSK Doctors, provides expert care and a supportive environment to guide you confidently through every stage of this journey.

Medical Tests and Consultations

Before your surgery, several important tests will help your medical team plan the best approach for you. These usually include MRI scans to see the full extent of your ACL injury, physical assessments to check your knee’s stability, and standard blood tests to ensure you are in good health.

You’ll also meet your orthopaedic surgeon to discuss the procedure, risks, and what to expect afterwards. An anaesthetist will explain how they will safely manage the anaesthesia. Choosing trusted specialists like Professor Paul Lee at MSK Doctors means you’ll benefit from clear, patient-centred consultations where your questions are welcomed, helping you feel well informed and prepared.

Optimising Your Physical Condition Before Surgery

In the weeks leading up to surgery, focusing on your physical fitness can make a real difference to your recovery. Prehabilitation exercises are highly encouraged—they strengthen key muscles around your knee, like your quadriceps and hamstrings, improve flexibility, and reduce swelling. These exercises ready your leg for the challenges of surgery and rehabilitation.

It’s equally important to avoid activities that might worsen your injury, so adapting your routine under professional advice is crucial. Eating a balanced diet and staying well hydrated will support your body’s healing process.

In the operating room, graft preparation is a vital step. Studies show that "circumferential compression of the graft prior to implantation significantly changes the size of the graft, and thus the size of the tunnels required for implantation" (Chan et al., 2019). This meticulous preparation improves how well the graft fits and functions.

There are also different ways to prepare the hamstring graft. Experts note that "a quadrupled semitendinosus (ST) graft provides a thicker tendon that better resembles the native ACL and reduces the risk of graft re-rupture" (Rovere et al., 2022). Your surgeon will choose the most suitable graft option tailored to your individual needs.

Innovative treatments are emerging too. Recent research into an injectable hydroxyapatite/collagen type I (HAp/Col I) composite found it promotes a regenerative environment for tendon-to-bone healing, supporting faster and stronger recovery (Liu et al., 2025). While not yet standard practice, such advances hold promise for future patients.

Throughout your preparation, the expert guidance from Professor Paul Lee and the MSK Doctors team will ensure you progress safely and confidently towards surgery.

Home Preparation Tips

Getting your home ready for life after surgery can greatly ease your recovery. Prepare a comfortable, accessible area close to essentials. Remove trip hazards such as loose rugs and keep paths clear. Arrange supportive furniture—chairs with armrests are helpful when your mobility is limited.

Be sure to gather key items on an ACL surgery checklist: crutches, ice packs for swelling, loose-fitting clothes to accommodate dressings, prescribed medications, and any recommended mobility aids.

It’s wise to organise help with everyday tasks—cooking, cleaning, or personal care—in advance. Having support will allow you to focus fully on healing during those crucial early days.

What to Expect on Surgery Day

On surgery day, arriving a few hours early allows time for hospital admission and final paperwork. You’ll receive clear fasting instructions (usually no food or drink for several hours beforehand) to keep you safe during anaesthesia.

Bring some personal essentials like identification, comfortable clothes, and any necessary medications. Arrange reliable transport to and from the hospital, and consider having a family member or friend accompany you for support.

You will be cared for by a skilled orthopaedic team, including Professor Paul Lee at MSK Doctors, committed to your safety and comfort. It’s important to remember that "graft integration depends on an optimal fit inside the bone tunnel” (Chan et al., 2019), so these technical details are carefully managed to maximise your outcome.

Approaching surgery with these preparations in place will help you feel calm and empowered as you begin your journey to recovery.

Conclusion

Preparing for ACL reconstruction is a step-by-step process that includes testing, physical readiness, home setup, and knowing what to expect on the big day. Thoughtful planning reduces stress and equips you to face surgery with confidence.

Relying on experienced professionals, such as Professor Paul Lee and the MSK Doctors team, will provide expert support throughout your recovery journey.

With proper preparation and expert care, you can look forward to a strong, positive recovery and the return to the activities you love.
