Patella (Kneecap) Pain, Instability, or Dislocation
A condition that causes the kneecap to track abnormally, leading to pain, giving way, or dislocation
Patella (kneecap) pain, instability, and dislocation are common knee issues, often affecting active individuals and those with underlying anatomical variations. These conditions can cause pain, swelling, and difficulty with movement. Dr Ben McGrath, an orthopaedic specialist, provides expert diagnosis and treatment options to relieve symptoms, restore stability, and improve knee function.

What is Patella Pain, Instability, and Dislocation?
Patella pain refers to discomfort around or behind the kneecap, often caused by overuse, injury, or alignment issues. Patella instability occurs when the kneecap moves out of its normal position, while patella dislocation involves the kneecap moving entirely out of its groove. Instability and dislocation may lead to pain and difficulty with activities that require knee stability, such as walking, running, or climbing stairs.
Common Symptoms of Patella Instability and Dislocation
Patients with patella pain, instability, or dislocation often experience the following symptoms:
- Kneecap Pain: Pain around the kneecap, especially during activities such as squatting, jumping, or climbing stairs.
- Knee Swelling and Stiffness: Swelling may occur around the kneecap, causing discomfort and restricting movement.
- Feeling of Instability or “Giving Way”: A sensation that the kneecap is slipping or not securely in place, particularly during movement.
- Visible Deformity (in Case of Dislocation): In cases of dislocation, the kneecap may appear visibly out of place and require medical intervention to realign.
- Clicking or Popping Sensations: Movement may cause a clicking or popping feeling within the knee joint.
If these symptoms persist, consulting Dr McGrath can help determine the cause and recommend appropriate treatments.
Causes and Risk Factors for Patella Pain and Instability
Several factors increase the likelihood of patella pain, instability, and dislocation:
- Anatomical Variations: Certain knee shapes or alignment issues, such as a shallow groove in the femur, can increase the risk of patella instability.
- Direct Trauma: A direct blow to the knee, falls, or high-impact collisions can lead to dislocation or instability.
- Weak or Imbalanced Muscles: Weakness in the quadriceps or other surrounding muscles may contribute to improper kneecap alignment.
- Overuse and Repetitive Stress: Repeated knee bending or overuse in activities such as running or jumping can lead to patella pain and instability.
- Previous Dislocations: A history of patella dislocation increases the likelihood of future instability or dislocations.
Dr McGrath considers these risk factors when diagnosing each patient and advising on prevention or treatment strategies.
Diagnosis of Patella Instability and Dislocation
Dr Ben McGrath uses a thorough diagnostic approach to confirm patella instability or dislocation:
- Physical Examination: Dr McGrath assesses knee alignment, stability, and pain. Specific tests may be used to evaluate patella movement and assess muscle strength.
- Imaging Tests: X-rays can help identify anatomical abnormalities or evidence of dislocation, while MRI may be recommended to assess soft tissue damage and rule out cartilage injuries.
An accurate diagnosis allows Dr McGrath to develop a targeted treatment plan based on each patient’s specific condition.
Non-Surgical Treatments for Patella Pain and Instability
Non-surgical management is often the first approach for patella pain and mild instability, with options including:
- Physiotherapy: A physiotherapist can develop exercises to strengthen the quadriceps, improve knee alignment, and stabilise the kneecap, reducing the risk of dislocation.
- Activity Modification: Avoiding high-impact activities or exercises that place strain on the kneecap can help manage symptoms.
- Knee Bracing or Taping: A knee brace or patellar tape may provide additional support, helping to keep the kneecap in place during activity.
- Medication: Nonsteroidal anti-inflammatory drugs (NSAIDs) can help alleviate pain and reduce inflammation. Always consult a healthcare provider before starting any medication.
- Ice Therapy: Applying ice to the knee after activities can help reduce pain and swelling.
These conservative treatments aim to relieve symptoms, improve stability, and support overall knee health.
Surgical Treatments for Patella Instability
Surgery may be recommended if conservative treatments are ineffective or if the patient experiences recurrent dislocations. Surgical options include:
- Lateral Release: This procedure involves releasing tight tissues on the outer side of the knee, allowing the kneecap to align properly in the groove.
- Medial Patellofemoral Ligament (MPFL) Reconstruction: In cases of recurrent dislocations, MPFL reconstruction uses a graft to stabilise the inner knee, preventing the kneecap from sliding out of place.
- Trochleoplasty: For patients with an unusually shallow groove in the femur, a trochleoplasty may be performed to deepen the groove and improve patella alignment.
Dr McGrath carefully considers each patient’s age, activity level, and knee anatomy before recommending surgery, ensuring a comprehensive approach to knee stability and recovery.
When to See Dr Ben McGrath for Patella Pain or Instability
If you experience persistent patella pain, a sensation of instability, or recurrent dislocations, a consultation with Dr McGrath can provide an accurate diagnosis and explore tailored treatment options to improve knee function and stability.
FAQs About Patella Pain, Instability, and Dislocation
Many cases of mild patella instability can improve with physiotherapy, bracing, and activity modification. Surgery is typically considered for recurrent dislocations or severe instability.
Recovery times vary depending on the specific procedure, but full recovery may take several months, with physiotherapy playing an essential role in regaining strength and stability.
Yes, strengthening the quadriceps, maintaining flexibility, and practising proper movement techniques can help reduce the risk of instability. A physiotherapist can provide a personalised program for knee health.
