What is patellofemoral instability?

Patellofemoral instability refers to the kneecap (patella) slipping out of its normal position, often leading to dislocation. It commonly affects young adults, athletes, and individuals with joint hypermobility or alignment issues.

What causes the kneecap to dislocate?

Kneecap dislocation can result from trauma, twisting injuries, or anatomical factors such as a shallow trochlear groove or poor patellar alignment. It is more common in active individuals and those with ligament laxity.

How is patellofemoral instability diagnosed?

Diagnosis involves clinical examination and imaging such as X-rays, 3T MRI, or CT scans to assess bone structure, cartilage damage, and alignment. Professor Chinmay Gupte performs a full biomechanical assessment during your consultation.

Do I need surgery for a dislocating kneecap?

Not always. Many first-time dislocations can be treated with physiotherapy. Surgery is recommended for recurrent dislocations or if imaging shows structural issues like ligament rupture or bone misalignment.

What surgeries can help stabilise the kneecap?

Procedures include MPFL reconstruction, trochleoplasty, tibial tubercle osteotomy, or lateral release, depending on the patient’s anatomy and dislocation severity. Professor Gupte tailors surgery based on each individual case.

What is a children's ACL injury?

A children's ACL injury refers to a tear of the anterior cruciate ligament in the knee, often caused by sports-related activities. In children, these injuries must be managed carefully to avoid damage to the growth plates.

How is ACL surgery different in children?

Children require growth-sparing ACL reconstruction techniques, such as all-epiphyseal or partial transphyseal methods, to protect open growth plates and ensure proper bone development.

Does every child with an ACL tear need surgery?

Not always. Some children can be managed with physiotherapy and activity modification. Surgery is recommended for ongoing instability or high-risk sports involvement.

What is the recovery time after paediatric ACL surgery?

Recovery typically takes 9 to 12 months, including physiotherapy, rehab milestones, and return-to-sport clearance under specialist guidance.
