Contrast arthrography in symptomatic varus knees.
The authors carried out a study of contrast arthrography in 48 cases of primary genu varum, i.e. not secondary to trauma or to pathological conditions of the hip or foot. The patients all had symptoms and were classified according to the commonly used Trillat-Dejour method into four groups or stages depending on the degree of varus and the radiographic and arthrographic findings. Associated lesions secondary to the basic pathology were observed in all cases. These ranged from hypertrophic synovitis to torn medial or lateral menisci up to total compromise of the joint typical of stage 4 arthritic varus knee. In these patients, contrast arthrography is useful in planning surgery, particularly high tibial osteotomy. It also enables the surgeon to decide whether complementary intra-articular measures are indicated without having to resort to arthroscopy. This is always a more invasive method, necessitating general anaesthesia, as these knees are quite painful and the arthroscopic access is difficult.
