Anterior Cruciate Ligament (ACL) Injuries

A famous football injury suffered by a high number of players over the years. In the past, this would have ended a player's career.

 

 

Famous Introduction

 

The ACL became known in football circles when England's 'Italia 90' hero, Paul Gascoigne of Tottenham, ruptured his in the 1991 FA Cup final. It was big news Gazza was about to join Serie A team Lazio in a multi-million-pound deal. The Italians reduced the transfer fee they offered because of the ACL injury.

The anterior cruciate ligament (ACL) is a main stabiliser of the knee joint. It is the connection between the thigh bone and the shinbone allowing the knee to twist and turn as one piece.

The ACL also prevents excessive forward movement of the shin in relation to the thigh and extreme rotation at the knee joint. Located in the middle of the joint it sits next to the posterior cruciate ligament.

Normally it's a non-contact injury. The player will plant their foot and push off. They'll hear a pop and fall to ground.

How it happens

 

Anterior cruciate ligament injuries happen a lot in sport, with football having more ACL incidents than others. Usually, when a footballer's anterior cruciate ligament 'goes' there's no one near them. Running with a sudden change of direction or an awkward landing have seen players end up on the ground in pain.

Nonetheless, there have been cases when an extreme force (a tackle high up) from the side to the knee has caused injury. 

Because of the amount of force that is required to damage the ACL it is not uncommon for other structures within the knee, such as the meniscus or medial ligament to also be damaged.

Statistics reveal an anterior cruciate ligament injury risk is higher in female footballers. They are 2 to 7 times more likely to injure the ACL than male players. Experts give different reasons why; some say it is because women have shorter ACL's, others say it could be down to how they land after jumping.  

 

 

 

What to look for

 

Either way, when it happens, players have described a 'popping' feeling in the knee. In some cases, the person may feel able to continue playing but, as soon as the knee is put under strain during sports activity, the knee joint will become unstable. The reason the person is unable to carry on is that the restraining function of the ACL is absent and there is more rotation and forward movement of the shin in relation to the thigh, making the knee joint unstable.

After a couple of hours, the knee joint will become painfully swollen due to what is called a haemarthrosis (bleeding within the joint). This swelling provides a protective function by not allowing the person to use their knee but, if it persists, it can cause complications during the rehab.

The cruciate can rupture when the ligament has only partly been damaged. A complete tear, on the other hand, will see it snapped in two. Most of the swelling goes, and a player with an injured ACL can usually walk. The knee is unsteady though and can give way.

 

 

Checking the damage

 

Immediately after the injury occurs and throughout the first 48-72 hours, an exact diagnosis is very difficult due to the swelling around the joint. The goals of acute physiotherapy treatment are to reduce knee pain and knee swelling.

Ice packs can be applied for periods of twenty minutes every couple of hours (never apply ice directly to the skin as it can cause an ice burn) to relieve pain and reduce bleeding within the tissue.

Once the initial treatment for the swollen knee has taken effect, a diagnosis can be made. This may be done with the medical personnel performing stress tests on the knee ligaments - the degree of laxity within the joint will allow the physician to estimate the degree of damage.

If there is any doubt, or to confirm the clinical tests, the patient is sent for further investigations. Most commonly an MRI scan is used to determine the severity of a knee injury.

However, in some cases, the MRI scan may not give a clear picture of the damage and it may be necessary to survey the joint with an arthroscope. The combination of these findings allows the orthopaedic consultant to build a picture of the extent of the damage.

 

 

Get it fixed

 

The treatment of the ACL injury depends on the severity of the injury and the subsequent functional impairment, the age of the patient and their level of sporting activity.

 

I snapped the ACL in my left knee. I was told I'd be out for 6 to 7 months. It ended up being 10. My left knee feels brilliant now.

If the diagnosis reveals only a partial tear of some of the fibres of the ACL, and there is minimal instability, then physiotherapy sessions and a knee brace are usually sufficient.

In the case of individuals who are involved in a high level of sport where a degree of instability is functionally unacceptable, ACL reconstruction knee surgery is the surest way to restore normal function.

Rehab

 

ACL reconstruction knee surgery has evolved beyond recognition since the first ACL repair in 1963. The development has continued since then and the latest surgical technique uses a strip of the patella tendon from the patient's knee as a graft to replace the ACL.

In addition to advances in the surgery, there have been improvements in rehabilitation after operations. This has returned players to the pitch successfully, in some cases, in less than six months.

 

Recovering From An Anterior Cruciate Ligament Injury

This injury used to end a footballer's career. The advances in surgery and rehabilitation methods means a return to the pre-injury levels is now possible..

 

 

Final Note

A ruptured ACL is still a big injury, but most players will recover from it with because of improved rehabilitation and recovery understanding. A career as professional can still be at the horizon for those that suffer an ACL injury early on.
