Patella Luxation
Surgical treatment is generally recommended for dogs with Grade III or IV MPL, frequent lameness associated with Grade II MPL, and animals with concurrent CCLR.
Surgical procedures aim to realign the quadriceps-patellar mechanism. While surgery is tailored to the individual patient, it usually involves trochleaplasty (wedge or block), re-alignment of the tibial tuberosity (tibial tuberosity transposition, anti-rotational suture), and imbrication of the stretched tissues (ie, lateral imbrication for MPL). Distal femoral osteotomy/ostectomy may be recommended for dogs with significant distal femoral varus.
Patella luxation has been shown to lead to stifle OA, particularly if CCL rupture occurs. Therefore, long term management of OA is recommended.
