Summary
# Editorial Summary: Bilateral Lateral Patellar Luxation Repair in a Foal Congenital lateral patellar luxation remains an uncommon orthopaedic presentation in horses, yet when it occurs—particularly bilaterally—it presents significant functional challenges requiring surgical intervention. The authors document the staged surgical management of a 2-month-old Italian Trotter foal using block recession trochleoplasty combined with polypropylene mesh reinforcement of medial imbrication sutures, an approach chosen specifically to address underlying bone deformities affecting patellar tracking. Intra- and post-operative imaging confirmed restoration of proper patellar positioning and quadriceps mechanism alignment, with positive functional outcomes achieved in both stifles. For equine practitioners encountering patellar luxation cases where bone deformities contribute to the condition, this combined technique offers a viable alternative to standard surgical approaches, potentially improving stability through mesh reinforcement of soft tissue repairs. Given the rarity of this condition, clinicians should consider early surgical referral when bilateral signs are present, as staged correction appears to yield favourable results without compromising rehabilitation or long-term function.

Practical Takeaways
- •Block recession trochleoplasty with polypropylene mesh reinforcement represents a viable surgical option for congenital bilateral patellar luxation in young foals when bone deformities are present
- •Staged surgical correction of both stifles allows individual assessment and optimization of each joint's mechanics
- •This technique may improve outcomes in patellar luxation cases where standard surgical approaches have limitations
Key Findings
- •Block recession trochleoplasty combined with polypropylene mesh reinforcement successfully corrected bilateral lateral patellar luxation in a 2-month-old foal
- •Staged surgical approach to both stifles achieved proper patellar positioning, tracking, and quadriceps mechanism alignment with positive functional outcomes
- •Polypropylene mesh application reinforced medial imbrication sutures and proved beneficial in managing cases with underlying bone deformities
