Hart, J.C.A.; Jann, H.W.; Moorman, V.J. Equine Veterinary Education June 2009 21 6 307-311(5) A 24-hour-old male Shetland pony was presented for evaluation of unilateral hindlimb lameness of unknown duration. Physical and radiographic findings confirmed a diagnosis of medial luxation of the patella. A traumatic or congenital aetiology was suspected but could not be confirmed. Surgical correction of the luxation, using a modified recession trochleoplasty technique, was carried out. At 6 months follow-up, no discernbile lameness could be observed. In the literature, descriptions of medially luxated patellae in equids are rare. Published reports describing the use of peri- and intra-articular surgical techiques for the correction of luxated patellae in equids are widely available. The modified recession trochleoplasty employed in this case may offer advantages over previously published techniques.
