Foal 3
At 6 months post discharge, Foal 3 showed a mild AAEP 3/5 RH lameness which was positive to global flexion. There was minimal palpable effusion of the right stifle, however there was a firm palpable swelling over the LM (Figure 4 c). Radiographs revealed mild soft tissue thickening over the R LFTJ. A radiolucent area, surrounded by a rim of sclerosis, could be seen on the lateral aspect of the tibial plateau, indicating development of a possible cystic formation (Figure 4 d). There was mild remodeling of the lateral tibial plateau and femoral condyle, which was flattened in appearance (Figure 4 e). Mineralization within the soft tissue in the region of the LM could be appreciated. Moderate hypoechoic effusion of SER was seen on US. The LM continued to protrude beyond the level of the condyles. Previously seen clefts were visible but had reduced in size, evidence of mineralization could be seen within the body of the meniscus which retained its triangular shape (Figure 4 b). Remodeling of the LFC could be appreciated, and a zone of irregular subchondral bone could be seen on the tibial plateau within the joint space.
