RidgeStop Procedure for Patellar Luxation (Dislocation of the Kneecap) Disease

At Abbotsford Animal Hospital, Dr. Derek Clark offers consultations and surgical services for the correction of patellar luxation. We can offer corrective surgery for patients with medial or lateral luxation of the kneecap.

Surgical procedures that we offer include Tibial Tuberosity Transposition, Sulcoplasty and less invasive procedures including RidgeStop Implants.

RidgeStop can be a “stand-alone” procedure for less severe cases of patellar luxation – Grade 2 or better. Alternatively, RidgeStop is employed as an adjunct procedure when re-alignment operations such as distal femoral ostectomy or tibial crest translocation are performed. In such cases, RidgeStop acts effectively as an alternative to sulcoplasty procedures. When used as an adjunct to a re-alignment operation, the re-alignment surgery is decided on and completed after the RidgeStop is applied as part of the same anaesthetic procedure.

How common is the surgery?

Patellar luxation is a common condition in dogs and uncommon in cats. RidgeStop surgery a state of the art, less invasive patellar luxation surgery that is limited in its availability in Canada. We are fortunate to have one of the only Canadian surgeons trained in this procedure.

What does RidgeStop use?

The surgery involves fixing a synthetic ridge implant (made of ultra-high molecular weight polyethylene) to the bone using 2 or 3 surgical screws to build up the sides of the patella groove where it is insufficient or eroded due to degenerative conditions.

What is the advantage of RidgeStop?

RidgeStop is much less traumatic, less evasive and more effective surgery than a Sulcoplasty.
