Anterior Cruciate Ligament or ACL Injury

International Elite Care provides rapid, expert management of your anterior cruciate ligament/ACL injury by leading specialist surgeons.

An ACL injury is a damage to the ligament situated at the centre of the knee joint. The anterior cruciate ligament connects the femur to the tibia and plays a fundamental role in knee stability. It is essential for everyday activities as well as sporting movements.

A knee injury involving the anterior cruciate ligament typically occurs following a trauma: twisting of the knee, a sudden stop, hyperextension or a direct blow. For example, a footballer may sustain an ACL injury during a rotational trauma on the pitch.

This condition can lead to joint instability, reduced mobility and, without appropriate management, may expose the knee to secondary damage, particularly to the menisci and articular cartilage.

Anterior Cruciate Ligament Tear: Diagnosis

Anterior cruciate ligament tear diagnosis is based on a meticulous medical evaluation combining clinical examination and imaging. The aim is to confirm the lesion, establish its severity and identify any associated knee damage.

Clinical Examination

During the consultation, the surgeon specialising in knee conditions analyses:

the circumstances of the trauma (twisting, sudden stop, impact),
the symptoms of the anterior cruciate ligament injury (pain, swelling, giving-way sensation),
the stability of the knee through specific ligament tests.

These anterior cruciate ligament diagnosis tests evaluate the state of the cruciate ligament, the cause of the lesion and whether the knee is stable or unstable.

Medical Imaging

MRI of the knee is the reference investigation. It allows:

confirmation of the anterior cruciate ligament injury,
assessment of the menisci, cartilage and other ligaments,
detection of any associated lesions.

X-rays may also be performed to rule out an associated fracture, particularly in the context of a traumatic knee injury where an ACL lesion is suspected.

ACL Injury Symptoms and Signs

ACL injury symptoms can vary in intensity depending on the severity of the lesion and any associated damage. However, several hallmark signs help to identify the condition.

A Common Anterior Cruciate Ligament Tear Symptom: Sudden Pain

At the moment of injury, patients often describe a sharp, sudden pain in the knee. This pain typically forces an immediate halt to the activity in progress, particularly during sport.

An unusual sound, sometimes described as a crack or a “pop”, may be felt at the time of trauma. This sign is highly suggestive of an ACL tear.

ACL Damage Symptoms: Swelling and Instability

In the hours following the injury, significant inflammation can develop, with rapid knee swelling. This is caused by a joint effusion (an abnormal accumulation of fluid within the joint).

Among the symptoms of an ACL sprain or tear, reduced mobility is also prominent. Certain movements become difficult or even impossible in the early stages, for instance, fully bending or straightening the leg.

Once the initial pain subsides, a sensation of the knee giving way may appear, particularly during walking, rotational movements or on uneven ground. This instability reflects the loss of the stabilising role of the cruciate ligament.

Risks if the anterior cruciate ligament injury is left untreated

Without appropriate treatment, an injury to the anterior cruciate ligament of the knee can lead to chronic knee instability. This increases the risk of secondary injuries, particularly to the menisci and articular cartilage, which can contribute to the development of premature knee wear.

Anterior Cruciate Ligament Injury Causes

The anterior cruciate ligament injury causes are predominantly traumatic.

The most common mechanisms include:

A sudden change of direction or pivot on a planted foot (common in football, basketball, skiing),
An abrupt deceleration or stop while running,
Hyperextension of the knee,
A direct blow to the knee, particularly from the side,
Landing awkwardly from a jump.

Contact sports and activities involving rapid pivoting carry the highest risk. Without appropriate management, an untreated anterior cruciate ligament tear can progress to chronic knee instability, increasing the risk of secondary meniscal and cartilage damage and potentially accelerating premature joint wear.

Anterior Cruciate Ligament Tear: Premium Treatment by Specialist Surgeons

International Elite Care manages anterior cruciate ligament tears with a treatment plan adapted to the patient’s age, activity level and the severity of the injury. Two pathways may be considered: non-surgical and surgical.

Non-Surgical Treatment (Functional Approach)

Non-surgical management may be suitable for patients without significant instability. It is based on:

functional rehabilitation to strengthen the muscles that stabilise the knee,
proprioception training to improve joint control,
sometimes the temporary use of a knee brace.

This approach can restore satisfactory comfort for daily life, but it does not repair the anterior cruciate ligament or ACL tear itself. Persistent instability may expose the knee to secondary damage, particularly meniscal lesions.

Surgical Treatment: ACL Reconstruction

In active patients, athletes, or those with instability, surgery is the gold-standard treatment. It is strongly recommended for a complete rupture and may be advised when a partial anterior cruciate ligament lesion is poorly tolerated.

The procedure involves reconstructing the ACL, since a completely torn ligament does not heal spontaneously. The new ligament is rebuilt using one of the patient’s own tendons, which progressively adapts to provide knee stability.

The operation is performed by arthroscopy, a minimally invasive technique using a camera introduced into the joint, allowing:

precise surgery,
limited incisions,
faster recovery.

In the majority of cases, other structures of the knee are also affected, particularly the menisci. The International Elite Care surgeons therefore carry out a complete exploration of the knee during the procedure, aiming to:

identify associated meniscal lesions,
favour repair by suture wherever possible, to preserve the meniscal tissue,
resort to partial meniscectomy only when repair is not feasible, and as sparingly as possible.

This approach reduces the risk of premature knee wear and improves long-term outcomes.

Rehabilitation After Surgery

Following treatment, rehabilitation is a key phase. It allows the recovery of mobility, muscular strength and joint stability.

Rehabilitation begins promptly after surgery or as part of the non-surgical pathway. At International Elite Care, it is adapted progressively to the patient’s goals, delivering comprehensive, premium and bespoke support.

FAQ – ACL Tear

International Elite Care expert surgeons answer all the questions you may have regarding ACL tears and injuries.

What are ACL tears?

ACL tears involve damage to the anterior cruciate ligament, a key knee stabiliser connecting the thigh bone (femur) to the shin bone (tibia). This injury often results from sudden twists, stops, or impacts during sports, leading to partial or complete ligament rupture.

Is surgery always necessary for an ACL injury?

No, surgery is not always required. The decision depends on several factors: knee stability, the intensity of anterior cruciate ligament injury symptoms, the patient’s activity level and personal goals. Certain well-tolerated lesions can be managed without surgery.

Can I live normally with a torn ACL?

Some people manage to adapt their daily routine, but persistent instability can limit activities, cause difficulty walking or encourage secondary knee damage. Appropriate management is therefore recommended to restore a reliable knee and preserve quality of life over the medium and long term.

Is the procedure painful?

When performed by experts such as the International Elite Care surgeons, ACL reconstruction uses minimally invasive techniques with modern pain management. Post-operative pain is generally well controlled with a tailored protocol. Most patients describe moderate, transient discomfort that is effectively managed by the medical team.

How long does recovery take after ACL reconstruction?

Recovery is progressive and depends on the treatment chosen and the patient’s situation. Rehabilitation begins promptly and extends over several months to restore mobility, strength and stability. Follow-up is an essential step to ensure a safe return to activities and a lasting result.

Can I consult a specialist quickly with International Elite Care?

Yes. International Elite Care facilitates access to specialist knee surgeons, with optimised appointment timelines. The goal is to offer a rapid, reliable and personalised assessment for appropriate management of the injury.
