[Results after primary suture of rupture of the anterior cruciate ligament. A 4-5 year follow-up].

Forty patients (40 knees) with acute isolated or combined lesions of the anterior cruciate ligament treated by means of primary suture without reinforcement were followed-up 4-5 years postoperatively. In 75% of the patients, follow-up examination revealed clinical instability of the anterior cruciate ligament but only 25% of these had noteworthy subjective complaints (Lysholm knee score less than 83) and no significant difference was observed between the median knee scores for the group of patients with unstable knees and those with stable knees. On the other hand, however, a significant decrease in the level of activity (Tegner activity scale) was observed in patients with unstable knee joints as compared with patients with stable knees. These patients compensated for the defective stability by reducing the level of activity. Primary suture without plastic reinforcement cannot be recommended as the method of treatment of acute lesions of the anterior cruciate ligament because it does not provide long-term stability in the majority of patients.

Arthroscopy in diagnosis and treatment of hip disorders.

Fourteen hip arthroscopies between January 1985 and May 1988 were reviewed. Included were ten women and four men with an age ranging from 12 to 76 years. Indications were avascular necrosis; loose bodies; osteoarthrosis, arthritis, or pain; and snapping hip. The diagnosis was verified in five cases, including arthroscopic removal of a loose body in one and resection of a plica bridging the space between the femoral head and acetabular roof in two patients. The diagnosis was rejected in three cases. In five cases, no pathologic changes were found. One arthroscopy was inconclusive because of a narrow field of vision in a dysplastic hip. No serious complications occurred. Hip arthroscopy is useful in diagnostics and surgical treatment of selected hip disorders. The rehabilitation time is short. Hip arthroscopy is, however, a technically demanding procedure.

Treatment of clavicular fractures. Figure-of-eight bandage versus a simple sling.

Seventy-nine out-patients with midclavicular fractures were included in a prospective, randomized trial comparing treatment with a figure-of-eight bandage and a simple sling. Sixty-one patients completed the study and were reevaluated clinically and radiographically after 3 months. We found that treatment with a simple sling caused less discomfort and perhaps fewer complications than with the figure-of-eight bandage. The functional and cosmetic results of the two methods of treatment were identical and alignment of the healed fractures was unchanged from the initial displacement.

Arthroscopic determination of patellofemoral malalignment.

Patellofemoral alignment was determinant by arthroscopy according to the degree of knee flexion at which the lateral facet, the patellar ridge, and the medial facet of the patella gained contact with the femur. The intraarticular pressure was 75 mm Hg. In 17 patients with a normal patellofemoral joint, the lateral facet aligned at a mean knee flexion of 20 degrees, the patellar ridge at 35 degrees, and the medial facet at 50 degrees. Twelve patients with patellar subluxation showed no difference in the alignment of the lateral facet, but differed significantly with regard to alignment of both the ridge and the medial facet with contact at a mean flexion of 55 degrees and 85 degrees, respectively. The median measurements in 20 patients with idiopathic anterior knee pain did not deviate significantly from the normal material. However, the dispersion was increased significantly, with eight patients having increased measurements consistent with malalignment and three having decreased measurements below the lower limit of normal alignment. Patients with idiopathic anterior knee pain apparently can be reclassified according to the arthroscopically determined alignment, which may prove important in the treatment of these patients.

Arthroscopy in acute knee injuries.

The diagnostic value of arthroscopy was evaluated in 148 patients with acute hemarthrosis and/or instability of the knee. The treatment planned after clinical examination was compared with the treatment given after arthroscopy. Seventy-nine per cent of the patients had ligamentous injuries; 59 per cent of tears were combined with other injuries, and 71 per cent were complete ruptures. Stability testing under anesthesia was most inaccurate for the anterior cruciate ligament, with 13 per cent false positive and 30 per cent false negative results. The planned treatment was altered as a consequence of arthroscopy in 31 per cent of cases. Without arthroscopy, the preoperative diagnoses would have been seriously wrong in 15 per cent of the patients. Twenty per cent of total anterior cruciate ligament ruptures would have been overlooked.

Glued periosteal grafts in the knee.

Periosteal grafting was performed in 4 patients with osteochondritis dissecans of the medial femoral condyle and 1 patient with osteonecrosis of the lateral femoral condyle following prednisone therapy. The lesions were drilled out deep into the cancellous bone. The periosteal graft was taken from the medial facet of the tibia and fixed to the excavated bony defect by the tissue glue Fibrinkleber Human Immuno (Tisseel). The patients were followed clinically, by arthroscopic examination and by radiography at 3, 6, and 12 months. After 1 year the borderline between the new and surrounding cartilage was hardly visible.

Legg-Calvé-Perthes' disease. Morphological studies in two cases examined at necropsy.

Specimens of femoral heads were studied at necropsy in two cases of Legg-Calve-Perthes' disease. One was that of a boy aged four years ten months who died from appendicitis; the other was from a boy aged six years who died from a malignant glioma. Both had been treated for one and a half years for Legg-Calve-Perthes' disease which was in a stage of repair at the time of death. The diseased femoral heads were moderately flattened but the surface cartilage was intact. Epiphysial bone and bone marrow were partly replaced by cartilage, fibrous tissue and granulation tissue, and new bone was being formed. Inflammatory reaction was inconspicuous. Enchondral bone formation was only slightly decreased, and the structure of the growth plate was undisturbed. There was no sign of systemic bone disease. In the first case the changes indicated that more than one episode of ischaemia had occurred, and an occlusion--probably from an old thrombus--was demonstrated in the posterior inferior retinacular artery of the femoral head. The last episode of ischaemia, furthermore, had caused infarction of part of the metaphysial bone. In both cases, the central area of the metaphysial bone of the affected femur contained fat, but there were few haemopoietic cells and it therefore looked pale. The findings are discussed in relation to previous work on the pathology in Legg-Calve-Perthes' disease, recent information on the vascularisation of the femoral head in children, and experimental and comparative animal studies.
