Over the knee is one of the common types of deviations structural deviations in a horse's knees. It is also known as the bucked knee. Over-the-knee and over such structural deviations in the knee are clearly visible when looking from a side angle. The deviation is forward in nature as the knee is located on an outward angle when compared to the leg. Although the structure exerts excessive strain upon the knees during a run, this condition is not considered to be too serious in horses. In fact most foals will experience a losing in the back joint and, hence, overcome this problem.
