Plain-English summary
Four cats with persistent patellar luxation (a condition where the kneecap slips out of place) underwent a new surgical technique called partial parasagittal patellectomy after standard surgeries failed to correct the issue. This method was developed specifically for cats, as their kneecaps have a different shape compared to dogs, making traditional treatments less effective. After the surgery, all four cats showed good recovery and improvement in their condition. However, the long-term effects of this new technique are still being studied.

Abstract
We describe a novel surgical technique used to correct feline patellar luxation (PL) where abnormal patellar tracking persists despite conventional corrective surgery. An anatomical difference between feline and canine stifles is that the feline patella is wider relative to the trochlear sulcus. This results in less constrained patellar tracking. Therefore, patellar subluxation is common in normal cats. It was noticed that in some feline cases with clinically significant PL, PL persisted intraoperatively despite performing the standard corrective procedures. We report a novel surgical technique - partial parasagittal patellectomy - to address the wide shape of the feline patella relative to the sulcus. This technique has been successfully performed in four cats with good outcomes. However, the immediate risks and long-term effects of partial parasaggital patellectomy are not known. We reserve this technique for surgical cases where PL cannot be controlled by conventional means.
