Subchondral Bone Cyst

The stifle joint is a common location for subchondral bone cysts, which almost always occur at the point of maximum weight bearing in the lower end of the inside of the femur, the medial femoral condyle. They occur most often in young horses when first starting serious work, but are also found in older horses.

Signs of Subchondral Bone Cyst

The horse shows a sudden onset of a variable degree of lameness. The lameness may be extremely subtle or very severe. The horse usually improves with box rest but the lameness recurs when work is resumed. There is only slight distension of the stifle capsule, if any.

Treatment of Subchondral Bone Cyst

Prolonged rest (6 to 9 months) results in soundness in approximately 60% of horses. In horses which fail to respond to rest surgery can be performed with a fair prognosis. Evidence of partial subchondral bone cyst filling and cartilage repair has been reported in many cases along with increased comfort and accelerated return to performance after using Vet-Stem Cell™ Therapy.
