          Abstract

          Na presente pesquisa, foram utilizados implantes teno-ósseos homólogos conservados em glicerina a 98%, na reparação do ligamento cruzado cranial, em 24 cães adultos pesando entre 15 e 30kg. Os implantes foram passados por um leito receptor preparado no fêmur e outro na tíbia e ancorados por meio de fios de poliéster em parafusos fixados respectivamente nas extremidades distal e proximal desses ossos. A articulação do joelho foi imobilizada por um período de 30 dias. Os animais foram distribuídos em dois grupos para as avaliações radiográfica, macroscópica e histológica do implante aos 60 dias (grupo B) e aos 90 dias (grupo A) de evolução pós-operatória. Em nenhum dos cães, houve evidência de fragilização do implante ou evidência radiográfica ou macroscópica de degeneração articular até os 90 dias de pós-operatório.

          In the present study, homologue bone-tendon implants conserved in 98% glycerin were used in the restoration of the cranial cruciate ligament in 24 adult dogs weighing between 15 and 30 kg. The implants were placed in a stratified layer prepared in the femur and the tibia and anchored with polyester filament fastened to the distal and proximal extremities of these bones, respectively. The knee joint was immobilized for a period of 30 days. The animals were distributed into two groups for radiographic, macroscopic and histological evaluation of the implant at 60 days after the operation for group B and at 90 days for group A. There was no evidence in any of the dogs of fragility of the implant, nor radiographic or macroscopic evidence of joint degeneration up to 90 days post-operative.

          The effects of immobilization on the characteristics of articular cartilage: current concepts and future directions.

          The purpose of this paper is to review current data and concepts concerning the effect of immobilization on articular cartilage in animal models. We also evaluate the methods to measure articular cartilage changes in humans. Studies looking at the effects of immobilization on morphological, biochemical, and biomechanical characteristics of articular cartilage are reviewed. Articular cartilage changes in immobilized animals include altered proteoglycan synthesis, as well as thinning and softening of the tissue. The overall thickness of articular cartilage in the knee decreases up to 9% after 11 weeks of immobilization and the deformation rate under test load increases up to 42%. Quantitative data about changes in human articular cartilage following immobilization are not available. This is mainly due to the lack of an accurate, reproducible, and non-invasive method to characterize articular cartilage. An understanding of the alterations in articular cartilage following short and long term immobilization in humans is essential for the optimization of rehabilitation programs. Refined imaging techniques combined with state-of-the-art visualization tools could allow the systematical monitoring of articular cartilage morphology changes in immobilized humans.

            Cyclops syndrome: loss of extension following intra-articular anterior cruciate ligament reconstruction.

            Arthrofibrosis is one of the recognized complications following traditional anterior cruciate ligament (ACL) reconstruction. With the advent of arthroscopic assisted ACL reconstructions, the extent of potential arthrofibrosis appeared to be less. However, 13 patients after intra-articular ACL reconstruction using a patella tendon autograft developed a similar symptom complex. In addition to postoperative loss of full extension, there was an audible and palpable clunk with terminal extension. These patients had similar arthroscopic findings of a nodule that formed anterolateral to the tibial tunnel placement of the graft. The arthroscopic appearance of the soft tissue mass with its surface vessels was reminiscent of a "cyclops." After arthroscopy with debridement and manipulation of the knee, extension was improved in all cases. The average range of motion immediately after the procedure was 6.0-130 degrees, compared with 16-103 degrees preoperatively. The range of motion at last follow-up averaged 3.8 degrees of extension and 138 degrees of flexion. All patients had greater than 130 degrees of flexion. There were no complications attributed to the manipulation and arthroscopic lysis of adhesions, and no patient experienced loss of graft integrity or knee stability. The "cyclops" nodule was examined grossly and microscopically and demonstrated peripheral fibrous tissue with a central region of granulation tissue in all specimens. In addition, two specimens were noted to include bony fragments and three specimens contained cartilaginous tissue.
