Introduction

If you’re about to have anterior cruciate ligament (ACL) repair surgery, or are simply considering it, you’re probably wondering what the journey ahead looks like. The ACL is a key ligament deep in the centre of your knee that keeps it stable and allows smooth, controlled movement. It is one of the most commonly injured ligaments, often damaged during sports or sudden twisting actions. Such injuries can seriously affect how your knee functions, and surgery may be needed to repair this vital structure.

As explained by recent experts, “The anterior cruciate ligament (ACL) is a ligament in the centre of the knee that functions as an important knee stabiliser.” This article will walk you through the entire process—from diagnosis to the first days after surgery—so you can feel informed and reassured. Under the care of specialists like Professor Paul Lee and the MSK Doctors team, your treatment will be professional, precise, and designed with you at the heart of it.

What Happens Before Surgery

Everything starts with a detailed assessment to understand the extent of your ACL injury. Your surgeon will perform a physical examination to check how stable and mobile your knee is. Imaging tests, such as MRI scans, then offer a clear picture of the ligament and any damage to the surrounding tissues. All this helps your medical team decide whether an ACL repair or a full reconstruction is the best way forward for you.

Before surgery, you will meet with your clinicians to discuss what to expect and how to prepare. You might be given specific exercises or advice to get your knee ready. It is important to know that although “reconstruction is largely acknowledged as the gold standard treatment option for ACL injuries,” some patients face issues afterwards, including graft failure or difficulties returning to sport. Because of this, there is growing interest in preserving the existing ligament through repair when possible. Throughout these visits, specialists like Professor Paul Lee and the MSK Doctors team will support you with clear explanations every step of the way.

The ACL Repair Surgery Experience

On the day of your surgery, you will arrive at a specialist clinic where the team will prepare you carefully and make sure you are comfortable. You will be given anaesthesia to keep you pain-free during the procedure.

ACL repair is often done using arthroscopy, a minimally invasive technique in which small keyhole incisions are made to access the knee joint. Your surgeon may directly fix your existing ligament or use modern materials that encourage it to heal naturally.

Advances in this area are promising. For instance, it has been shown that “ACL repair in young children using this technique negates the requirement and potential morbidity of graft harvest and demonstrates the potential for excellent outcome as an attractive alternative to ACL reconstruction, where an adequate ACL remnant permits direct repair.” Over the last decade, there has been renewed focus on repairing rather than replacing the ligament because it can offer benefits like “decreased surgical morbidity, faster return of range of motion, and minimally invasive surgery.” Thanks to the skill and experience of the surgical team, including Professor Paul Lee, your operation will be conducted with the utmost precision, safety, and care. After the procedure, you will be closely monitored before being prepared for discharge or further recovery care.

Initial Recovery and Rehabilitation Timeline

The days immediately following your surgery are mainly about managing pain and protecting your knee. You will probably use crutches to avoid putting full weight on the leg, while gentle knee movements will start early on to prevent stiffness. Usually, patients go home within a day or two.

Physiotherapy begins soon after. In the first few weeks (weeks 1 to 3), the focus is on controlling swelling and gently restoring knee movement. From weeks 4 to 6, therapy shifts towards rebuilding strength and improving stability. Your progress will be regularly checked to adjust exercise plans as needed.

Looking further ahead, the typical recovery timeline aims for you to regain full motion and muscle strength within 3 to 6 months. Returning to normal daily activities is a gradual process, and when the time is right—usually around 6 to 12 months—you may begin a cautious and supervised return to sports to prevent reinjury.

Factors That Influence Your Recovery

Remember, every person’s recovery is different. How quickly and well your knee heals depends on many things, including your age, overall health, activity level, and how closely you follow your physiotherapy programme. Healing takes time, so patience is crucial.

Research emphasises the importance of the repaired ligament regaining its strength. One study explains: “Techniques that provide a higher stiffness to the repaired ACL may be required to mitigate the post‐traumatic osteoarthritis commonly seen after ACL injury.” In other words, a stronger repair can help protect your joint from long-term damage. With a skilled team like Professor Paul Lee and the MSK Doctors supporting you, your rehabilitation plan will be personalised to help achieve the best possible outcome.

Practical Guidance and Addressing Common Concerns

It’s perfectly natural to worry about pain, swelling, or whether your knee will regain full stability. Managing discomfort generally involves pain relief prescribed by your healthcare team and elevating your leg to reduce swelling.

You might also be wondering how your healing will be monitored. Modern imaging techniques bring reassurance here. Research points out that “MRI T2* can be used as a noninvasive estimation of ligament stiffness,” meaning your doctors can evaluate how well your ligament is healing without further invasive procedures.

Setting realistic recovery goals helps manage expectations and reduce anxiety. Always feel free to communicate openly with your healthcare providers, asking questions about exercises, progress, or any issues you notice. The MSK Doctors team, guided by experts like Professor Paul Lee, are approachable and ready to support you compassionately throughout your recovery.

Conclusion

Recovering from ACL repair surgery is a gradual journey that requires patience, professional care, and your active participation. With expert support from Professor Paul Lee and the MSK Doctors, you will receive personalised treatment designed to restore your knee’s stability and function effectively.
