The Ellison iliotibial-band transfer for a torn anterior cruciate ligament of the knee. Long-term follow-up.

We studied the long-term results of the Ellison technique of extra-articular transfer of the iliotibial band, without advancement of the biceps tendon, as the sole operative treatment for a torn anterior cruciate ligament. Thirty-two patients (thirty-two knees) were evaluated an average of eleven years (range, seven to fifteen years) after the operation. The average age at the time of the operation was twenty-two years (range, sixteen to thirty-four years). Eighteen patients (56 per cent) had a modified Lysholm score of less than 84 points, indicating symptoms during the activities of daily living. Only six patients (19 per cent) had a subjectively normal knee (a modified Lysholm score of more than 94 points). The most common reason for a poor subjective score was the presence of symptoms of instability, in twenty-four patients (75 per cent). Twenty-four patients (75 per cent) had a positive pivot-shift test and twenty-nine patients (91 per cent), a positive Lachman test. Twelve patients (38 per cent) had severe (grade 3 or 4) radiographic changes. The radiographs of the knee appeared normal (grade 0) in only eight patients (25 per cent). There was a significant association between a meniscal injury and radiographic changes (p < 0.05). Fourteen patients (44 per cent) had subsequent procedures due to persistent instability or pathological changes in the articular cartilage or in a meniscus. There was a significant decline in the subjective and objective knee scores in the twenty-one patients who were evaluated at both two and eleven years. The number of patients who had a positive pivot-shift test increased from five (24 per cent) to sixteen (76 per cent). Subjectively, the number of patients who had a good result decreased from fourteen (67 per cent) to five (24 per cent). Objectively, nine patients (43 per cent) had a rating of good at two years; this fell to three (14 per cent) at eleven years. Symptomatic instability, pain, and a positive pivot-shift test were the most common reasons for a poor result. Because of the decline in the subjective and objective scores, we no longer recommend the Ellison procedure as the sole operative treatment for a torn anterior cruciate ligament of the knee.
