[Complications after total knee arthroplasty].

Complications after total knee arthroplasty were evaluated prospectively after a total of 321 procedures. 53 (16.5 %) patients showed postoperative courses deviating from the routine. Of these 5.0 % developed clinically relevant deep vein thromboses, the rate of deep infections was 1.6 %, 3.7 % of the patients suffered from persisting or recurrent joint effusions, arthrofibrosis was observed in 4.4 % of the patients and 1.9 % were affected by wound complications. In most patients deep infections were treated by removal of the implants and reimplantation after clearing of the infection. The primary treatment of arthrofibrosis consisted of manipulation under general or regional anaesthesia. Patients with recurrent joint effusions received punctions, which had to be repeated in some cases. In one patient an intraarticular drainage had to be inserted. The conservative or surgical therapy of wound complications depended on the patient's situation. In patients with thrombosis distal to the trifurcation of the popliteal vein anticoagulation with heparin was continued. In contrast, in patients with femoral or popliteal venous thrombosis the anticoagulation was changed to cumarine derivates.

[Chemonucleolysis. Development, experiences, prospects].

Concerning the so-called minimal invasive procedures currently available for the treatment of lumbar disc prolapse (percutaneous endoscopic discectomy, APLD, laser decompression, chemonucleolysis), the intradiscal application of Chymopapain represents the method with the longest period of clinical use and experience. Long-term studies have shown good clinical results. When considering of the indication and the few contraindications--particularly allergic diathesis--chemonucleolysis provides a low-risk, efficient, minimally invasive therapy that closes the therapeutic window between conservative and open surgical treatment.

[Triple pelvic osteotomy (according to Tönnis and Kalchschmidt) in the treatment of acetabular dysplasia--medium-term results].

AIM: The triple pelvic osteotomy according to Tönnis and Kalchschmidt has gained major significance in the surgical treatment of acetabular dysplasia in adolescents and adults. The curative and prophylactic potentials of this operative procedure are reviewed in this study by means of a clinical and radiological follow-up trial. METHODS: 34 patients/38 hip joints treated by the triple pelvic osteotomy between 1996 and 2005 were reviewed clinically and radiologically with an average follow-up of 3.5 years. The radiological classification into grades of deviation was done according to Tschauner et al., clinically the preoperative Harris hip score was determined, as well as common epidemiologic parameters. At follow-up, the preoperatively determined radiological and clinical parameters were controlled and subjected to statistical analysis using Student's t-test for the comparison of means between two paired groups. Finally, the subjective assessment of the operation's result by the patients was registered. RESULTS: A statistically highly significant amelioration of the Harris hip score, relevant radiological angles and grades of deviation could be demonstrated at follow-up. This fact coincided with a high or very high patient satisfaction in 81.7% of the cases. The conversion rate to alloarthroplasty was 2.6%. The complication profile was within the scope of similar elective hip surgeries. CONCLUSION: The triple pelvic osteotomy according to Tönnis and Kalchschmidt has shown in the present study a high and constant potential with regard to reduction/absence of disorders as well as a statistically highly significant amelioration of clinical scores and relevant radiological angles. In our experience, this surgical method can be regarded as the joint-preserving method of choice in the cardinal indication of adolescent and adult acetabular dysplasia.
