Patella dislocation, also known as knee cap dislocation or patella instability, is a common knee injury that occurs when the knee cap comes out of its groove. This can happen due to a blow or an awkward twist of the knee, resulting in torn or stretched tissues around the knee.

Fortunately, in most cases, a brace is not required for treatment, and patella dislocation can be managed with simple measures. Initial treatment focuses on controlling pain and swelling through the principles of RICE (Rest, Ice, Compression, Elevation). Recovery involves exercises to regain full function, flexibility, and strength, with a typical recovery time of 6-8 weeks.

Key Takeaways:

• Patella dislocation occurs when the knee cap comes out of its normal position in the front of the knee.
• Treatment for patella dislocation usually involves a tubigrip bandage and the RICE principle.
• Walking and exercise are important for recovery, guided by a physiotherapist.
• The time frame for returning to normal activities varies but is generally around 6-8 weeks.
• In some cases, surgical treatment may be necessary to stabilize the patella and prevent further dislocations.

What is a Patella Dislocation? (Dislocated Kneecap)

A patella dislocation, also known as knee cap dislocation, occurs when the knee cap comes out of its normal position in the front of the knee. This can happen due to a blow or an awkward twist of the knee. The patella normally glides within a groove in the thigh bone when the leg is bent or straightened. When the kneecap dislocates, it comes out of the groove and can cause tearing or stretching of the surrounding tissues.

Patella dislocation can result in patella instability, where the knee cap is prone to further dislocations. This condition can cause significant pain and impact daily activities. It is important to understand the causes, symptoms, and treatment options for patella dislocation to effectively manage this injury and prevent future instability.

Treatment for Patella Dislocation

In most cases, a brace is not required for the treatment of patella dislocation. The injury can be managed simply with a tubigrip bandage. Crutches may be used initially to help with walking without limping. Simple pain relief medications, such as over-the-counter pain relievers, can be taken to manage pain. Rest, ice, compression, and elevation (RICE) are important in the initial stages of treatment. Physical therapy is usually recommended to regain full range of motion and strength. Surgical treatment may be necessary for recurrent dislocations or when there is significant damage to the knee.

If conservative measures do not provide sufficient relief or if there is structural damage to the knee, patella dislocation surgery may be recommended. Surgery aims to stabilize the patella and prevent further dislocations. The specific surgical procedure will depend on the individual case, but some common approaches include:

1. Medial patellofemoral ligament (MPFL) reconstruction: This procedure involves recreating or repairing the ligament that helps keep the patella in its proper place.
2. Tibial tubercle osteotomy: In this procedure, a small piece of bone is removed or repositioned to realign the patella and improve its stability.
3. Lateral release: This procedure involves releasing tight or contracted structures on the outer side of the knee to relieve pressure on the patella.
4. Cartilage repair or transplantation: If there is damage to the cartilage in the knee joint, procedures such as microfracture, autologous chondrocyte implantation, or osteochondral transplantation may be performed to repair or replace the damaged tissue.

Following surgery, a comprehensive rehabilitation program will be prescribed to aid in the recovery process. This may involve a combination of physical therapy, exercises, and gradual return to normal activities. It is essential to follow the post-operative instructions provided by the surgeon and engage in regular follow-up appointments to ensure proper healing and optimal outcomes.

Initial Treatment for Patella Dislocation

The initial treatment for patella dislocation involves controlling pain and swelling. Following the RICE principle (Rest, Ice, Compression, and Elevation) is crucial for an effective recovery.

Rest

Resting the affected knee is essential to prevent further strain and promote healing. Avoid putting weight on the injured leg and take breaks when needed. This allows the damaged tissues to repair themselves properly.

Ice

Applying ice to the knee can help reduce pain and swelling associated with patella dislocation. Wrap ice in a cloth or use a cold pack and apply it to the affected area for 10-15 minutes at a time. Remember to never apply ice directly to the skin to avoid frostbite.

Compression

Use a tubigrip bandage or compression wrap to provide support and reduce swelling. Make sure the compression is firm but not too tight, as it may restrict blood flow. This helps stabilize the knee and promote healing.

Elevation

Elevating the leg above heart level can significantly reduce swelling. Find a comfortable position where your leg is supported, such as using pillows or a recliner. This allows excess fluid to drain away from the knee, aiding in the healing process.

Gentle Exercises

Performing gentle exercises is crucial for maintaining mobility and preventing stiffness in the knee. Ankle and knee movements can be beneficial to promote blood circulation and prevent muscle atrophy. However, it is important to consult with a healthcare professional or physiotherapist before starting any exercise regimen.

By following these initial treatment steps, you can effectively manage the pain and swelling associated with patella dislocation. Remember to consult with a healthcare professional for comprehensive guidance and personalized recommendations.

Walking and Exercise after Patella Dislocation

After experiencing an isolated patella dislocation, it is crucial to gradually reintroduce walking as soon as possible. 

However, it is important to be assessed first to ensure it is just an isolated dislocation. It may be something else, which means it is NOT ideal to walk on it.

Walking on the injured leg helps strengthen the muscles and prevent further instability. To walk normally, remember to strike your heel to the floor first, straighten your knee, and then push off from your toes. This proper walking technique promotes proper alignment and stability in the knee joint.

If you find that walking without pain or instability is challenging, don’t hesitate to use crutches for support. Crutches provide an additional level of stability and can aid in maintaining balance while you recover.

In addition to walking, exercise plays a crucial role in the recovery process after a patella dislocation. Exercise should be gradually introduced to regain strength and flexibility in the knee. It is essential to follow the guidance and recommendations of a physiotherapist to ensure a safe and effective recovery.

A physiotherapist can create a tailored exercise plan that addresses your specific needs, taking into account your current range of motion and strength. This plan may include exercises such as leg lifts, squats, lunges, and stretches to improve muscle strength and flexibility in the knee joint. Regularly performing these exercises can help prevent future dislocations and promote overall knee stability.

Note: Always consult with a healthcare professional, such as a physiotherapist or orthopedic specialist, before beginning any exercise program. They can assess your condition and provide appropriate guidance for your specific situation.

Patellofemoral Instability and Recurrent Dislocation

Patellofemoral instability is a condition characterized by the recurring dislocation or subluxation of the patella, commonly known as the kneecap. This instability often occurs in individuals with underlying ligament laxity, where the ligaments that hold the patella in place are weak or stretched.

Recurrent patellar dislocations can lead to more severe damage to the knee joint with each occurrence. The patella may repeatedly come out of its normal position, causing pain, swelling, and difficulty in movement. Over time, this instability can result in cartilage damage and early-onset osteoarthritis.

To manage patellofemoral instability, a conservative approach is usually initially recommended. This may involve periods of rest, followed by a gradual return to activity while focusing on strengthening the surrounding muscles and improving overall joint stability. Strengthening exercises, such as quadriceps and hip muscle strengthening, can help support the patella and prevent further dislocations.

In some cases, a patellar buttress brace may be prescribed to provide additional support and stability to the patella during activities. The brace helps align the patella within its groove, reducing the risk of dislocation.

If conservative management fails to provide adequate stability and symptom relief, or if the instability persists, surgical intervention may be necessary. Surgical procedures for patellofemoral instability aim to address the underlying causes of the instability and prevent further dislocations.

Surgical options may include:

• Medial patellofemoral ligament (MPFL) reconstruction: This procedure involves reconstructing the torn or stretched ligament that helps keep the patella in place.
• Tibial tubercle osteotomy: In cases where the alignment of the patella needs to be corrected, a small cut is made in the tibial tubercle bone to reposition it and realign the patella.
• Lateral release: This procedure involves releasing tight structures on the outer side of the patella, allowing it to track properly within the groove.

Recovery from surgical stabilization procedures varies depending on the specific procedure performed and may require a few weeks to several months. Physical-therapy and rehabilitation are crucial components of post-surgical recovery, helping individuals regain strength, flexibility, and normal function of the knee joint.

Risks and Complications

As with any surgical procedure, there are potential risks and complications associated with surgical treatment for patellofemoral instability. These may include infection, blood clot formation, damage to nerves or blood vessels, and failure of the procedure to completely address the instability.

It’s important for individuals considering surgery to discuss the potential risks and benefits with their healthcare provider to make an informed decision about the most suitable treatment approach.

Surgical Treatment for Patella Dislocation

Surgical treatment may be necessary for patella dislocation, especially in cases of recurrent dislocations or significant knee damage. The goal of surgery is to stabilize the patella and reduce the risk of further dislocations, providing long-term relief and improving overall knee function.
