    Notizen: Summary A group of 94 male and 12 female patients who all suffered from ACL ruptures had a follow-up examination after a period of 14 to 21 years (m = 17.2 years). Each of them had undergone a primary arthrotomy with total or partial meniscectomy. In none of the cases, however, had operative repair of the ACL rupture been performed. The most frequent concomitant injury was a torn medial meniscus which occurred in 74.5% of the cases whereas a damaged lateral meniscus was found in 17.0% of the cases only. Chondromalacia of tibia, femur or patella was observed in 42.5% of the cases. Over 60% of the patients resumed their former sports activities, although in nearly 30% of these cases at a lower level whereas one third of the patients had to practice some other sport or were even forced to give up sports completely. 61.3% still complained about instability of the knee joint, 73.6% of the patients with partial or total meniscectomy had developed osteoarthritis of grade III and IV.

    Notizen: Abstract Based on the fact that high-Tc superconductors exhibit strong fluctuations, we have allowed the presence of pair fluctuations in the framework of the T-matrix formalism using the 2-D negative Hubbard model for temperatures above and below Tc. Our equations are fully self-consistent. For T ≥ Tc the electronic properties change drastically with respect to BCS treatment, namely, there is a pseudogap around the chemical potential in the density of states, and the spectral function, A(k,ω), vs. ω exhibits a double peak structure which is related to the appearance of this pseudogap. For T ≤ Tc, we have generalized the formalism in order to include the order parameter.
