Knee Ligament Injuries: Causes, Treatment and Recovery

Previously, we published a blog article looking at the function of the ACL in the Knee, knee ligament injuries, especially those affecting the Anterior Cruciate Ligament (ACL), are a common concern among individuals who engage in physical activities, sports, or lead an active lifestyle.

ACL injuries can cause severe knee pain, instability, and limit one's mobility. In such cases, reconstructive ACL surgery might be the best solution. In this blog, we will explore the overview of knee ligament injuries, preparation for surgery, and the recovery journey to help individuals make an informed decision about their treatment options.

Valiant Clinic & Hospital, a leading orthopedic clinic in Dubai, offers state-of-the-art treatments for knee ligament injuries. Our team of experienced surgeons and physiotherapists will guide you through the entire process and ensure that you receive the best care and rehabilitation.

Overview of Knee Ligament Injuries

The knee is a complex joint consisting of bones, ligaments, tendons, and cartilage. The ligaments are fibrous bands that connect bones and provide stability to the knee joint. ACL injuries occur when the ACL is stretched, torn, or ruptured, causing instability and pain. Common causes of ACL injuries include sudden changes in direction, landing awkwardly, or direct contact.

The most commonly injured ligament in the knee is the anterior cruciate ligament (ACL), which provides stability to the knee and prevents excessive rotation. ACL injuries can occur due to sudden movements, cuts, or rotations during physical activities, such as playing sports, running, or jumping.

ACL injuries can range from mild sprains to complete tears and can cause significant pain, instability, and limited mobility. In severe cases, reconstructive ACL surgery may be necessary to restore stability and function to the knee.

Deciding to Have Knee Ligament Surgery

The decision to undergo reconstructive ACL surgery can be complex and should be made after careful consideration of all factors involved. While conservative treatment such as physiotherapy, bracing, and medication can be effective for managing mild to moderate knee ligament injuries, surgery may be necessary for severe cases.

Some of the key factors to consider when deciding whether to have ACL surgery include:

Severity of the injury

If the ACL is completely torn or the knee joint is unstable, surgery may be necessary to restore stability and prevent further damage.


The recovery time and success rate of ACL surgery can be influenced by the individual's age. In younger individuals, the ACL has a higher potential for healing, while in older individuals, the healing process may be slower.

Physical Activity Level

For individuals who are highly physically active, surgery may be necessary to regain their pre-injury level of function and participate in physical activities without pain or instability.

Growth and development

For children and adolescents, the growth and development of the bones and the effect of surgery on future growth should be carefully considered before deciding to have surgery.

Preparing for Surgery

Undergoing ACL surgery can be a daunting experience, but with the right preparation, individuals can ensure a successful and smooth recovery process. There are several factors that need to be considered before and during the preparation phase to help minimize risks and ensure the best possible outcome.

Pre-Admission Tests and Evaluations

Before the surgery, individuals must undergo a series of tests and evaluations, including X-rays and other imaging tests, to determine the extent of their injury and ensure they are fit for the procedure.

Cleanliness and Hygiene

It is important to keep the knee clean and free from infection before and after the surgery. Regularly washing and disinfecting the knee can help reduce the risk of infection and promote healing.

Healthy Diet

A healthy and balanced diet is important to optimize muscle function and support the body during the recovery process. Individuals should aim to eat a diet that is rich in protein, vitamins, and minerals to support healing and recovery.

Physiotherapy and Stretching Exercises

Physiotherapy and stretching exercises can help prepare the knee for the surgery and improve postoperative recovery. These exercises can help to increase circulation, flexibility, and strength in the knee, reducing the risk of complications and promoting healing.

Stopping Smoking

It is well known that smoking has a negative impact on the healing and recovery process. Individuals who smoke are advised to quit smoking several weeks before the surgery and during the recovery period to help reduce the risk of complications and promote healing.

In addition to the above, it is important for parents to consider the child's age, developmental stage, and overall health when preparing for ACL surgery. Children may have different needs and require additional support and care during the recovery process. It is important to discuss these factors with a pediatric orthopedic specialist to ensure that the child receives the best possible care and support.

How is the Surgery Performed?

Reconstructive ACL surgery is a common procedure that is performed to replace a damaged or torn anterior cruciate ligament (ACL) with a new graft tissue. The goal of the surgery is to restore stability and functionality to the knee joint, allowing individuals to return to their normal activities.

There are several different types of ACL reconstruction surgery, each with its own specific techniques and graft options. The type of surgery that is performed depends on a number of factors, including the severity of the injury, the patient's age, and their activity level.

The most common grafts used for ACL reconstruction surgery include:


Autografts are tissues that are taken from the patient's own body and used to replace the damaged ACL. The most common autografts used for ACL reconstruction are the patellar tendon, hamstring tendon, and quadriceps tendon.


Allografts are tissues that are taken from a donor and used to replace the damaged ACL. The allograft tissue is usually harvested from cadavers and thoroughly screened for any potential diseases before being used in surgery.

The selection of the graft material depends on several factors, including the patient's age, activity level, and medical history. The surgeon will discuss the different options with the patient and recommend the best course of action based on their individual needs and circumstances.

The surgery is usually performed using arthroscopy, a minimally invasive surgical technique that uses small incisions and a camera to visualize the knee joint. During the procedure, the surgeon will examine the knee and determine the best course of action. The damaged ACL will be removed, and the new graft will be inserted in its place, anchored to the bones using special screws or sutures.

The Road to Recovery Post-Surgery

The recovery journey after ACL surgery is a gradual and often challenging process that requires patience, dedication, and support. The timeline for recovery varies depending on a number of factors, including the individual's age, overall health, and the type of ACL surgery performed.

In general, the first two weeks of recovery are focused on reducing swelling and pain, and improving mobility. During this time, the individual may be prescribed pain medication, and will likely be encouraged to engage in light physical activity, such as walking and gentle knee stretches.

Over the next six weeks, the individual can gradually increase their physical activity and start performing knee-strengthening exercises, under the guidance of a physical therapist. Some common exercises used to strengthen the knee after ACL surgery include quadriceps sets, hamstring curls, and calf raises.

Physical therapy is a crucial component of ACL surgery recovery, as it helps to optimize muscle function, improve range of motion, and prevent reinjury. The options for physiotherapy are diverse and may include manual therapy, exercise therapy, and electrotherapy. Our physiotherapy clinic in Dubai has an excellent track record in helping patients of our orthopedic surgeries to recover the maximum range of motion and flexibility possible.

After six months, the individual can typically return to work and start driving again. However, it may take up to a year for the individual to regain full strength and stability in their knee.

Research has shown that recovery rates vary among different age groups. For example, a study published in the American Journal of Sports Medicine found that younger individuals tended to have faster and more successful recoveries than older individuals, due to their increased physical activity levels and overall health.
