Patellar Instability
Patellar instability occurs when the kneecap (patella) moves out of its normal position, often due to injury, ligament laxity, or anatomical variations. This condition can lead to pain and recurrent dislocations.
If you experience a sensation of the kneecap slipping or moving out of place, pain around the kneecap, or swelling after a knee injury, these could be signs of patellar instability. Frequent dislocations may also occur.
Living with patellar instability can make you cautious about using your knee, especially during activities like running, jumping, or even walking. Fear of dislocation can limit participation in sports and daily activities.
Dr. Khoo will diagnose patellar instability through a physical exam and may use imaging tests, such as X-rays or an MRI, to assess the alignment and stability of the patella.
Surgery, such as patellar realignment or ligament reconstruction, may be necessary for recurrent dislocations or if conservative treatments do not improve stability. Dr. Khoo will discuss the best approach based on your symptoms and activity level.
If surgery is needed, Dr. Khoo will explain the procedure, such as patellar realignment, and how it can stabilise the kneecap and prevent further dislocations. You’ll receive detailed information on the surgical process, recovery, and how to prepare, so you feel comfortable and confident throughout your treatment.
Dr. Khoo will carefully evaluate your symptoms and review your medical history. He will discuss the nature of your condition and explain both non-surgical and surgical treatment options. You will leave the consultation with a clear understanding of the best approach to restore knee stability and function.
In many cases, non-surgical treatments such as physiotherapy, knee bracing, and activity modification can effectively manage patellar instability. Surgery is usually considered for severe cases with recurrent dislocations.
Recovery after patellar realignment surgery typically takes 3–6 months, depending on the success of rehabilitation and adherence to the recovery plan. Full return to activities may take longer.
Most patients can return to sports after patellar realignment surgery, but it is essential to follow a comprehensive rehabilitation program. Dr. Khoo will provide guidance on when it is safe to resume sports and other activities.
