Randomized Controlled Trial Comparative Study Clinical Trial
[Clinico-histologic comparison of allogenic and autologous bone-tendon-bone using one-third of the patellar tendon in reconstruction of the anterior cruciate ligament].
Reconstruction of the ruptured anterior cruciate ligament (ACL) using modern techniques achieves successful long-term results in up to 90% of all cases. Yet the discussion continues as to the suitable implant to replace the ACL in terms of donor morbidity, implant reaction, long-term results, and potenzial risk of carrier concerning the allograft. The clinical and histological results from 2 years experience with the BPTB allograft (Tutoplast) and the BPTB autograft for ACL reconstruction are compared with reference to stability, functionality, rerupture rate, and histological reaction of the remodelling process. ⋯ There were clearer and more protracted indications of hypercellularity and hypervascularity, and the collagen matrix had not regularly aligned longitudinally even 1 year later. A detailed analysis of the BPTB allograft group indicated that especially in young and very sporty patients there is increased elongation of the implant and a clearly higher rerupture rate. Hence, according to the data we have collected, it would seem that the use of the BPTB allograft (Tutoplast) is not suitable especially in young patients who frequently practice high-level sports involving high knee stress.

Review Case Reports
[Bilateral atraumatic epiphysiolysis of the head of the tibia].
We report above a 14-year old boy, who suffered from a bilateral epiphyseal fracture type Salter/Harris II of the proximal tibia within four weeks without having an adequate trauma. Accompanying injuries were not found. ⋯ On both sides we achieved a correct axis and length in a uncomplicated healing with free joint movement. On the base of the result of our treatment we show a literature review of this rare form of epiphysiolysis.

Randomized Controlled Trial Comparative Study Clinical Trial
[Reduction of severe cardiac complications during implantation of cemented total hip endoprostheses in femoral neck fractures].
Intraoperative circulatory and pulmonary problems occuring during the repair of femoral neck fractures with cemented hip arthroplasty are a common problem, that cannot be ultimately explained. As a possible reason for this problem is air embolism during the polymerisation of the methylmethacrylat discussed. We started a prospective randomised clinical examination with 72 patients to prove the efficiency of palacos mixed in vacuum, with respect to the reduction of severe cardiovascular complication during endoprosthetic repair of femoral neck fractures. ⋯ Mortality in the control group amounted to 13.8% in the vacuum group to 2.8%. Through the use of methylmethacrylate mixed in vacuum for surgical repair of femoral neck fractures with cemented hip arthroplasty, the incidence of severe cardiac complications could be reduced significantly. Patients with increased pulmonal arterial pressure have the highest risk for cardiac complications.

Case Reports
[Retrograde tibial intramedullary nailing with the Flex Nail--treatment of tibial fracture in an unusual case].
We report a case by a 75 year old female patient suffering a third-degree open fracture of the shinbone with a severe damage of the soft tissue. Primary operation was a temporary fixation with a fixateur externe and a radical debridement of the soft tissue with vacuum-sealing. Ten days later we did the definitive surgery. ⋯ The defect of the soft tissue was treated by a muscle flap and meshgraft transplantation. Healing of the soft tissue and beginning consolidation of the fracture comes after 4 months. In our opinion the retrograd inserted Flex-Nail is a good option for treatment of compound fractures of the lower leg in special cases.

40 acute traumatic ruptures of the Achilles tendon were evaluated in a prospective study after open repair using an early functional rehabilitation protocol. The age of the patients averaged 43 (23-64) years. The operation consisted of a Kessler suture and microadaptation of the tendon. ⋯ There were no perioperative complications. One rerupture occurred 6 weeks postoperatively and was operated successfully. The combination of surgical repair and early functional after treatment resulted in normal function after 1 year, but requires cooperation of the patient.
