[4-year results following Insall anterior cruciate ligament-plasty].

From May 1984 until December 1987 56 anterior cruciate ligament reconstructions were done in cases with single plane anteromedial instability, using the bone block iliotibial band transfer. The anterior distal part of the iliotibial tract with its osseous insertion from Gerdy's tubercule was used. The immediate fixation of the bone block by a screw or by threads to the tibia allows early motion of the knee, because no immobilization is necessary. There were 56 patients: 14 women, 42 men; 34 right, 22 left. About the same number (65) with more severe multiplane laxity had been treated by other methods for reconstruction or augmentation of the anterior cruciate ligament. The average follow-up is 25.06 (6-52) months for these patients (12.88). All patients had full extension of the involved knee. None had an effusion and only eight complained of occasional pain. At follow-up some laxity was detected by the anterior drawer test and Lachman test (20 degrees). The LYSHOLM Score was very high at the time of follow-up = 98.67 points.

[Arthroscopy and MRT of the shoulder--a comparative retrospective analysis].

MR Imaging is proving to an effective means for evaluating the shoulder. The use of a surface coil and high resolution scanning techniques have allowed detailed analysis of normal anatomy and suspected pathology of the shoulder. On the other way arthroscopic inspection provides a more extensive visualization of the joint in different positions. 31 patients, well documented, were studied with MR Imaging and correlated with findings in arthroscopy and open revision in some cases. The MR studies were retrospective interpreted without the knowledge of the results of other diagnostic procedures. For the evaluation of rotator cuff tears MRI proved to have a sensitivity of 83.3% and an accuracy of 90.3%. When Arthroscopy was correlated with open revision the sensitivity was 61.8% and the accuracy 78%. Labral pathology and Hill-Sachs lesions will be better evaluated in arthroscopy as in MRI (sensitivity of arthroscopy 100% and of MRI 69%, accuracy of arthroscopy 100% and of MRI 87.1%). With the high resolution scanning technique and a surface coil MRI has been shown to be useful in the evaluation of rotator cuff tears and impingement syndrome but not in diagnosis of labral pathology and Hill-Sachs lesions.

[Synovitis villonodosa pigmentosa of the foot--diagnosis, therapy and long-term course].

The typical clinical cause of articular pigmented villonodular synovitis consists of progressive and painful swelling of the involved joints, bursae and tendons. The roentgenographic manifestations of this condition are usually nonspecific and consist of occasional superficial osseous erosion and cystic changes. Although these appearances may suggest the correct diagnosis, the precise diagnosis depends on examination of the tissue. Pigmented villonodular synovitis is a non-malignant disease entity of controversial origin and nature. The intraarticular form is characteristically monoarticular and affects predominantly the knee, the hip and the foot. We present 15 cases of pigmented villonodular synovitis of the foot, treated in a period from 1960 to 1986. In 11 patients the clinical and radiographic results were reviewed at an average of 15 years (rage: 3-26). The treatment of 5 recurrences and the differential diagnosis are discussed.

[Difficulties and complications in arthroscopic meniscus surgery].

Arthroscopic meniscectomy is one of the most sophisticated techniques in arthroscopic surgery. The actual meniscus resection is a simple surgical exercise - most problems and difficulties arise from the arthroscopic technique. With the aid of legholder, water pumps, video cameras, miniature instruments, motor-driven shavers and Laser-systems (Excimer) it would be possible, to reduce technical problems. Broken instruments are mostly the fault of the surgeon, because force is applied to the delicate tools in tight cavities. It is not just the instrument, which suffers in such cases, but the cartilage of the joint. Several examples of meniscus tears are described to show the possibilities, difficulties and complications of arthroscopic meniscus surgery.

[Diabetic osteoarthropathy. Course and differential diagnosis].

Diabetic neuropathy with reduced sensitivity to pain and mechanical overloading of the joints, associated with frequently disturbed circulation in the lower extremities, are the etiopathogenetic factors of diabetic osteoarthropathy (synonyms: neuroarthropathia diabetica, Charcot joint). In the first stage there is osteonecrotic destruction of bone and cartilage. Clinically, an insidious, painless, noninflammatory hydroarthrosis with massive swelling of the soft tissues is typical. Subsequently, in stage II, irregular transformation of the bone due to multiple resorptive processes occurs. In the third stage this transformation process stabilizes and the bone ends become more pointed and more sclerotic (resembling a licked candy stick). For mechanical reasons, the tarsometatarsal and metatarsophalangeal joints and the metatarsals are primarily affected. However, destruction is also seen in Chopart's joint, the talus, the calcaneus, the ankle joint and the distal tibia. With regard to differential diagnosis, similar clinical pictures are seen in many neuropathic bony changes--tabes dorsalis, syringomyelia, myelodysplasias, congenital analgesia, congenital familial acroosteolysis. More difficult to differentiate are osteomyelitic foci, bone tuberculosis, and malignant bone tumors involving bone destruction.
