Ligament Surgery

Common Causes

• Sports injuries. Ligament tears are among the most common sports injuries. A sudden change of direction or a landing on an awkward angle can tear a ligament instantly. The ACL and the ligaments of the ankle and shoulder are particularly vulnerable.

• A direct blow or impact. Direct force applied to a joint can rupture one or more ligaments without the joint needing to twist. The PCL is a common example.

• Repeated partial injuries. Multiple minor sprains to the same ligament, without allowing proper healing between them, can leave the tissue weakened and stretched over time, leading to chronic instability even in the absence of a single clear-cut rupture.

• Dislocation. When a joint dislocates, the force involved can stretch or tear the ligaments that hold it in position. In the shoulder particularly, repeated dislocations cause progressive damage to the surrounding structures that often requires surgical repair to resolve.

Benefits

• Restored stability. The most direct outcome of ligament surgery is a joint that can be trusted again: one that does not give way during normal activities or exercise.

• Pain relief. The instability caused by a damaged ligament creates abnormal movement within the joint, which leads to pain and, over time, progressive damage to the cartilage and bone. Restoring stability addresses the root cause of both.

• Protection of long-term joint health. An unstable joint that is left untreated places abnormal stress on the surrounding structures. Over time, this accelerates wear and increases the risk of arthritis. Ligament surgery performed at the right time can significantly slow this process.

• Return to sport and activity. For active patients, a stable joint makes a return to sport and physical work possible. A well-executed ligament repair followed by a committed rehabilitation programme gives patients the best chance of a full return to the pre-injury level of activity.

Common Ligament Procedures

ACL Reconstruction

The ACL is one of the main ligaments running through the centre of the knee, and one of the most commonly torn in sport. Because the ACL has a very limited blood supply, a completely torn ACL will not heal on its own. Reconstruction involves replacing the torn ligament with a graft, most commonly taken from the patient's hamstring tendon, which is secured in the correct position. Over several months, the graft gradually integrates with the surrounding bone, effectively becoming a new ligament.

PCL Reconstruction

The PCL is the strongest ligament in the knee and is most commonly injured through a direct blow. Some PCL injuries can be managed without surgery, but where instability is significant, reconstruction using a graft restores stability to the back of the knee.

Labral Repair and Shoulder Stabilisation

In the shoulder, the labrum (the ring of fibrous cartilage around the socket) and the surrounding ligaments work together to keep the joint stable. A dislocation can tear the labrum and stretch these ligaments, leaving the shoulder chronically unstable. Arthroscopic labral repair reattaches the torn labrum to the rim of the socket using small bone anchors, restoring the depth and structure of the joint. This significantly reduces the risk of further dislocations and halts the progressive damage that repeated instability would otherwise cause.

Lateral Ankle Ligament Reconstruction

Repeated ankle sprains can stretch the ligaments on the outside of the ankle to the point where they can no longer provide adequate support. When the ankle feels persistently unstable, surgical reconstruction tightens and repairs the damaged ligaments, restoring reliable stability and allowing the patient to return to activity with confidence.

What to Expect Prior to Surgery

1. A pre-operative assessment. Dr. Barrett will review the patient's symptoms through examination (typically an MRI) to confirm the diagnosis and plan the surgery. General health is also assessed to make sure the patient is fit for the operation and anaesthetic.

2. A medication review. Patients may be asked to stop certain medicines (such as blood thinners or anti-inflammatory drugs) in the days before surgery.

3. Final surgery preparation. The patient may be asked not to eat or drink for several hours before the operation. It is also worth preparing the home environment before surgery, such as everyday items within easy reach all make the early days of recovery more comfortable.

What to Expect During Surgery

Ligament surgery is performed under either a general anaesthetic (the patient is fully asleep) or a regional anaesthetic (the joint is numbed while the patient remains comfortable). Dr. Barrett will recommend the most appropriate option. Most procedures take between 1 and 2 hours.

1. The joint is accessed through small keyhole incisions (arthroscopic approach) or a carefully placed open incision, depending on the joint and the nature of the repair.

2. Where a graft is being used, it is harvested from the appropriate donor site, prepared, and sized before being positioned within the joint.

3. The graft or repaired tissue is secured in place using anchors, screws, or sutures, depending on the technique and the joint.

4. The stability and alignment of the joint are assessed before closing and dressing the incisions.

What to Expect During Recovery

Recovery from ligament surgery requires patience. The repair needs time to heal properly, and the rehabilitation programme is fundamental to achieving the best possible outcome. The following is a general guide:

Days 1 – 14

Rest and protection of the joint are the priority. Swelling, bruising, and discomfort are normal and will ease gradually. A brace or sling may be used to protect the repair.

Weeks 2 – 6

Physiotherapy begins with gentle movement exercises to restore range of motion without placing stress on the healing tissue. The pace of progression is guided by how the joint is responding.

Weeks 6 – 12

Strengthening work becomes the focus as the repaired ligament or graft consolidates. Most patients are returning to light daily activities during this period.

Months 3 – 12

Full recovery, particularly following ACL or PCL reconstruction, typically takes between 9 and 12 months before a return to competitive sport. Dr. Barrett will guide the patient's return to activity based on clinical assessment at each stage of recovery. A premature return to demanding activity before the graft has fully matured is one of the most common reasons for re-injury, which is why rehabilitation is so important.
