Stabilising the patella to restore normal knee function
Overview
Patellofemoral stabilisation refers to a range of surgical procedures aimed at treating instability of the kneecap (patella). When the patella does not track properly within the groove at the end of the thigh bone (trochlea), it can cause pain, repeated dislocations or subluxations (partial dislocations), and damage to the cartilage. Stabilisation procedures improve patellar tracking and prevent further episodes of instability, preserving knee function and reducing pain.
Example of Patellofemoral Stabilisation
Postoperative xray of partially healed peri-acetabular osteotomy
Indications
Surgery for patellofemoral instability is typically considered when:
Surgical Approach
Open approach with controlled cuts around the acetabulumTesting
The socket is rotated and fixed with screws to increase coverage
Often combined with arthroscopy or labral repair
Meticulous planning with 3D imaging and templating
Risks
Bleeding or nerve injury (especially femoral or sciatic nerve)
Infection
Blood clots
Delayed bone healing
Over- or under-correction requiring revision
Recovery Timeline
Peri-acetabular osteotomy is an involved procedure with extended post-operative recovery, however patient satisfaction is very high once this has occure
Typical Recovery
Hospital stay: 3–5 days
Crutches: ~6 weeks, then gradual weight bearing
Return to desk work: 6–8 weeks
Return to sport: 4–6 months
Frequently Asked Questions
Yes. It’s designed to preserve the natural joint in young people.
What is the subvastus approach and why is it used?
The subvastus approach avoids cutting the quadriceps tendon and preserves muscle function. This can lead to faster recovery, better early mobility, and less post-operative pain.
How long will my knee replacement last?
Most modern implants last 15–25 years or more, depending on your weight, activity level, and implant design. We select durable implants suited to your needs.
Can I kneel after a knee replacement?
Many patients can kneel again after surgery, although some find it uncomfortable at first. We’ll guide you through safe ways to try this once healing allows.
Will I be able to return to sport?
Yes — most people return to low-impact activities like walking, cycling, golf, swimming, and hiking. Running and high-impact sport are not recommended due to wear risk.
Is it normal to hear clicking in the new knee?
Yes — most patients notice a clicking or tapping sound, especially early on. This is due to the movement of the implant and is generally not a cause for concern.
Will I need physiotherapy after surgery?
Absolutely. A structured rehab program is essential. It helps restore flexibility, strength, and confidence in your new knee.
What if I’ve had previous surgery or deformity?
Total knee replacement can still be performed. Robotic assistance is especially helpful in these cases to plan and execute the surgery with precision.
