Forty-eight men and three women were reviewed an average of thirty-one months after pes anserinus transposition for chronic anteromedial rotational instability of the knee. Their ages ranged from eighteen to forty-two years (average twenty-five years). All but four of the injuries occurred during sport. The interval between injury and operation averaged thirty months. During this time twenty-three patients had had other operations of which eighteen were for excision of menisci. A further sixteen patients required excision of one or both menisci at the time of pes anserinus transposition. After operation large haematomata had to be expressed from four wounds. One patient had a pulmonary embolism All made a complete recovery. Worthwhile improvement of stability during activity was found in forty-two of the fifty-one knees. Pre-existing degeneration of articular cartilage associated with severe instability of long duration was the main cause of failure. Good motivation was important for success. Four grades of disability are described according to the severity of symptoms. It was found that a successful operation gave approximately one grade of improvement on this scale. Arthroscopy is recommended to identify torn menisci and degenerative changes before pes anserinus transposition is undertaken. An important advantage of this operation is its simplicity. When more elaborate ligamentous reconstructions are necessary for severe instability, pes anserinus transposition can be usefully added to complete the repair.

The case histories of 361 subcapital fractures of the femoral neck in 354 patients treated by primary replacement with the cemented Thompson prosthesis were reviewed, and 156 survivors were seen at follow-up. The average age was eighty-one years. Three hundred and thirty fractures occurred in women and thirty-one in men. The antero-lateral approach to the hip was used at all operations because it allows immediate and unrestricted mobilisation after operation. It is considered that this method is the best treatment in the rehabilitation of elderly patients after high femoral neck fractures, because of its low morbidity and high success rate in returning the geriatric orthopaedic patient to independence. The results after an average of just over three years were available for 161 hips in 156 patients studied at follow-up. Of these, 132 (82 per cent) were satisfactory. Most of the unsatisfactory results were in patients under seventy-five years of age. Out of the whole group of 361 hips treated the important early complications were wound infections in seventeen hips 4-7 per cent), all of which resolved, and dislocation in seven hips (2 per cent). Forty-six patients (12-9 per cent) died during the first four weeks after operation, their average age being eighty-five. One hundred and seventy-one patients (47-4 per cent) were discharged from hospital within under four weeks of the operation. Acetabular erosion and loosening are shown to be the important later complications. Three patients had late sepsis.
