Recurrent Patellar Dislocations in Telangana
The patella (knee cap) is a tiny bone protecting your knee joints. It is found in front of the knee in a groove termed the trochlear groove. It lies at the junction of the femur (thighbone) and tibia (shinbone). Articular cartilage is found beneath the patella and at the end of the femur cushion. It aids in the smooth movement of the bones as the legs move.
A network of soft tissues stabilizes and supports this joint. The medial patellofemoral ligament (MPFL) binds the inner side of the patella to the inside of the knee, preventing it from slipping away. Patellar dislocation results from ligament damage.
When the knee cap moves out of the trochlea, it results in patellar dislocation. A recurrent patellar dislocation occurs when the patella dislocates on many occasions. After two occurrences of dislocation, the chance of future dislocation increases to almost 70% to 80%.
Dr. Rajesh Thunuguntla is renowned for providing advanced and result-oriented treatment for recurrent patellar dislocations in Telangana. He is one of the best arthroscopic surgeon in Telangana, providing comprehensive and high-quality orthopaedic care to patients suffering from cartilage injuries or arthroscopic issues.
Several factors can increase the chances of patellar dislocation, including:
- Weaker thigh muscles.
- Patella that sits too high on the thigh bone.
- Excessive pronation of the feet — inward roll of the feet during walking or running.
- Weak and strained ligaments from prior patellar dislocations.
What are the Causes of Recurrent Patellar Dislocations?
A variety of factors can cause recurrent patellar dislocation. Among them are the following:
Specific hereditary characteristics include:
- Knee cap that is too far up in the groove
- The trochlear groove is shallow.
- Lateral ligaments that are too tight.
- Valgus leg alignment (knock-kneed legs).
- Trauma (twisting, bending, etc.)
- Immature skeletal muscles.
Each dislocation causes soft tissue stretching and increases the likelihood of recurrence.

Symptoms of Recurrent Patellar Dislocations
The following are some of the most common symptoms of recurrent patellar dislocation:
- Knee pain and swelling around the knee cap.
- Knee instability.
- Sense of repeat dislocation.
Diagnosis of Recurrent Patellar Dislocations
Dr. Rajesh Thunuguntla has a wealth of experience diagnosing and treating patients with recurrent patellar dislocations in Telangana. The doctor may examine your patella to see any soreness or edema.
Images of your knee can be taken with:
- CT scan
- MRI scan

Treatment of Recurrent Patellar Dislocations
Depending on the severity of the condition, Dr. Rajesh Thunuguntla can treat recurrent patellar dislocations in Telangana with non-surgical or surgical procedures.
- If your knee cap has dislocated only once or twice, your doctor may recommend conservative treatment.
- With medication and practice, the initial goal of treatment is to ease discomfort.
- To manage inflammation, the doctor may advise employing PRICE, which stands for Protect the injured joint, Rest, Ice at the injured site, Compression, and Elevation of the leg.
- The doctor may suggest using a brace, cast, or splint for a short period of immobilization. They may also try to stretch the structures on the outside of your knee and prescribe particular exercises to help you strengthen your muscles.
- Analgesics and nonsteroidal anti-inflammatory medications may be prescribed to reduce pain and swelling.
- The surgeon may recommend surgery when non-surgical treatment fails to relieve the symptoms of recurrent patella dislocation.
- Arthroscopy will be used in the first step of any realignment procedure to correct the dislocation.
- Arthroscopy is a minimally invasive procedure. It involves inserting surgical instruments into the affected region through two or three tiny incisions.
- Any loosely adhering fragments on the wounded surface can be wiped away.
- Your doctor will next decide on a surgical strategy based on the causes of dislocation.
- The surgeon creates tiny holes in the patella and femur to reconstruct the torn medial patellofemoral ligament.
- A portion of the hamstring tendon (tissue connecting the back of the thigh to the knee) is put into the holes to replace the torn MPFL.
- With the help of screws and anchors, the surgeon places the tendons in position.
- Your surgeon will surgically correct the patella to fit into the groove of the thigh bone if it is high seated. The tibial tuberosity (part of the tibia) is moved to do this.
- The surgeon uses the screws to clasp the tuberosity and keep it in place until it heals completely.
- Trochleoplasty is a procedure that involves reshaping or deepening the groove on the lower end of the femur. In this procedure, the surgeon may remove some bone, and the patella is kept in place by sutures or nails that dissolve over time.
- Your doctor may instruct you to use crutches and wear a brace for the first several post-surgery weeks.
- Following the healing of the bone, the doctor may offer physiotherapy. They may also teach simple exercises to help the knee function normally and prevent swelling. In a few months, you can perform the complete exercise.
- Dislocations can be avoided, and complete healing can be accomplished. However, it may necessitate surgery.
- Surgically treated patients take 1-6 months to recover from, depending on the level of cartilage injury and the amount of repair done.
- With more damage and a higher likelihood of recurrence, the patients may need more aggressive treatment choices to keep the condition from rapidly worsening.
Frequently Asked Questions
When will I be able to bend my knee again after a patellar dislocation?
The knee is immobilized for four to six weeks after a dislocation. Motion is resumed after a subluxation when the pain has subsided enough to be tolerated. After a subluxation, most patients can begin range of motion and strengthening exercises within a week.
How long do you have to wear a knee brace after a dislocation?
Your doctor may recommend wearing a hinged knee brace for at least six weeks throughout rehabilitation. You will require crutches for a while and gradually resume full weight-bearing over several months. Your physiotherapist will show you how to do safe exercises to strengthen your knee muscles and prevent stiffness.
How long does swelling last after a patellar dislocation?
When a free fragment has not formed, the usual treatment for a patellar dislocation is to immobilize the knee for a brief time (seven to 10 days). The swelling goes down, and the acute discomfort of the dislocation goes away during this time.
Is it possible to walk without a patella?
Though the kneecap is not required for walking or bending your leg, it improves muscle efficiency and reduces tension between the upper and lower leg. Squatting and climbing stairs can exert up to seven times your body weight on the kneecap and the joint behind it.
Is it possible to prevent knee dislocation using a knee brace?
A functional brace helps stabilize the knee joint. This brace can help you avoid a knee injury if you have a structural issue in or around your knee, such as weak ligaments or susceptibility for knee dislocation.
