[Standardized shoulder examination with reference to computerized isokinetic strength testing (Cybex II)].

The complexity of shoulder movement makes it difficult to test normal or pathological shoulder function, as well as therapy results after injury. There are also problems to classify therapy results and to compare those with the results of other persons or other treatment methods. The aim of this paper is to introduce a standardised examination method of the shoulder and a standardised score regarding "subjective feelings", "clinical examination", "technical examination" such as x-ray, CT, sonogram, and "computerised isokinetic strength test", which enables us to conduct a follow-up case study of different patient groups after shoulder injury. Standardised examination programmes of the most common shoulder injuries like AC separations, rotator-cuff tears and luxations of the shoulder are given in this paper. A retrospective study of surgically treated AC separations Type III at the Staatliche Orthopädische Klinik München/Harlaching showed that therapy results can be established with the help of this score. The efficacy of different treatment methods (e.g. Bosworth and tension-band wire) can be both elucidated and compared.

The cruciate ligaments in knee replacement.

The cruciate ligaments were resected with their bony insertions during total knee arthroplasty carried out in 12 patients with severe rheumatoid or osteoarthritis. The ligaments were examined histologically and biomechanically, using ten specimens from healthy adults as a control. A significant difference was found in the tensile stiffness and viscoelastic properties of the ligaments between the arthritic and the control group. The ligaments in the rheumatoid knees had a distinctly inferior tensile strength compared with the osteoarthritic knees. Total knee replacement, which also replaces ligament function, should therefore be considered in severely damaged rheumatoid knees.

[Does excessive stress play a role in the development of osteochondrosis dissecans tali?].

At the follow-up examination of 61 patients with Osteochondrosis dissecans tali (OD) we found at 48 of them one or more injuries in the anamnesia. More than 70 percent of them had as an injury mechanism a supination trauma. In case of medial OD the possible cause of an OD is given by the ratio 34 to 12 of trauma and non-trauma. The ratio in case of a lateral OD is 14 to 1 and it almost definitely points to overstress being a cause of it. Primary reasons may be here sports, especially football.

[Postoperative evaluation of osteochondrosis dissecans of the talus with special reference to medial malleolar osteotomy].

58 out of 69 patients after open operation for osteochondritis dissecans (OD) of the upper ankle joint were reexamined retrospectively. In 44 cases the medial talar edge was concerned, in 15 the lateral one. Pain in activity resisting conservative treatment led to the operations. 31 excisions, 16 drillings, 10 autogenous bone graftings (2 external) and 2 diagnostic arthrotomies had been carried out. Medial malleolar osteotomy had to be performed in 22 cases, mainly concerning excisions and graftings to maintain sufficient survey of the lesion. Follow-up examination took place an average 67 months postoperatively. The results were obtained through a new scoring system with special regard to subjective and clinical criteria. 13 excellent, 29 good, 10 fair and 7 bad results were obtained. Results depended mainly on operative approach, location of the lesion and in lateral OD time of operation. Medial malleolar osteotomy frequently led to local osteoarthritis and less favourable clinical findings. No significant difference could be realized for size of the lesion and the applied operative technique. Stage and age at time of operation did not clearly influence the outcome. The indication for operation must be made dependant on individual complaints. Even in the era of arthroscopy medial malleolar osteotomy sometimes is necessary, but goes along with higher morbidity and worse prognosis. Operations have to be carried out according to stage and followed by proper rehabilitation to render proper assessment. Lateral lesions result from sprains and should be operated early.

[Long-term results of the tibial head pendulum osteotomy in varus and valgus gonarthrosis in the elderly].

Proximal tibia-head osteotomy is an approved surgical method for the treatment of unilateral knee arthrosis. In a follow-up examination of 44 patients with 56 operated knees the long-term results more than 10 years after surgery are evaluated in older patients with varus and valgus arthrosis. It can be demonstrated that, if the indication is right, excellent long-term results can be expected, also for older patients with unilateral gonarthrosis. A fixation with metal implants seems to be unnecessary, and the complication rate is low.
