    ABSTRACT: Estrogens act on estrogen receptors distributed in articular cartilages, synovial membrane, and ligaments, which are thought to be related with degenerative changes. Meanwhile, progesterone is known to have a weak anabolic action on bone formation This study evaluates the effects of estrogen and progesterone hormone on bone/cartilage turnover in ovariectomized (OVX) rats. Thirty-five 7-month-old female Sprague-Dawley rats were randomly divided into 5 groups and then ovariectomized bilaterally except the sham control group. The first and the second group acting as controls did not receive hormonal therapy, the third group received estrogen, the fourth group received progesterone, and the fifth group received combination of both hormones 10 weeks after surgery. Evaluations were done using the serum levels of cartilage oligomeric matrix protein (COMP) for cartilage turnover, collagen type I C-telopeptide (CTX-1) and osteocalcin (OC) for bone turnover at 11, 15, 19 weeks after OVX and histology using the Osteoarthritis Research Society International (OARSI) osteoarthritis (OA) cartilage histopathology assessment system. Significantly less cartilage degradation (decreased levels of COMP) was found in the combined hormone treated group in comparison with OVX group. Similarly, both hormonal treatment resulted in increased bone formation and decreased bone resorption i.e., a low overall bone turnover status (decrease in the serum OC and CTX-1 levels). Combined estrogen and progesterone therapy was found to be convincing in terms of reducing the severity of OA in this experimental model.

    ABSTRACT: The purpose of this study was to evaluate the reliability of the PowerPoint (PP) (2007 Version; Microsoft, Redmond, Wash) method for measuring polyethylene liner wear after total hip arthroplasty. Seventeen retrieved polyethylene liners were included in this study. Wear volumes were calculated using the PP, the Dorr and Wan, and 3-dimensional (3D) laser scanning methods. Spearman correlation coefficients for wear volume results indicated strong correlations between the PP and 3D laser scanning methods (range, 0.89-0.93). On the other hand, Spearman correlation analysis revealed only moderate correlations between the Dorr and Wan and 3D laser scanning methods (range, 0.67-0.77). The PP method can be used to monitor linear wear after total hip arthroplasty and could serve as an alternative method when computerized methods are not available.

    ABSTRACT: Damage to soft tissues, chondral surfaces, and the menisci may result from imprise or overly aggressive establishment of portals in arthroscopic knee surgeries. In this note, we address the relationship between the skin and the capsule at portal sites according to knee positions. Understanding the skin-capsular mismatch may facilitate arthroscopic procedures and indirectly reduce the operation time.

    ABSTRACT: We evaluated the usefulness of radiographic parameters for osteoporosis by analyzing the results of radiographic parameters determined by digital hip radiographs and bone mineral density T-scores, as assessed by Dual Energy X-ray Absorptiometry (DEXA).

    ABSTRACT: Rapidly destructive coxarthrosis may be caused by osteoarthritis, osteonecrosis of the femoral head and rheumatoid arthritis, but its etiology has not been clarified. Rapidly destructive coxarthrosis generally occurs in old age patients and the patients clinically show severe pain, but a relatively preserved range of motion. Rapidly destructive coxarthrosis is characterized by a rapid destruction, resorption and subluxation of the femoral head, destruction of the articular area in the acetabulum, above 50% or 2 mm/year loss of the joint space and minimal osteophyte formation. The radiologic changes are dramatic and they may mimic neuropathic or septic arthritis. We report here on three cases of rheumatoid arthritis that had acute destruction of the hip joint and rapid resorption of the femoral head, and we also review the relevant medical literature. We recommend taking repetitive radiographs for rheumatoid arthritis patients who suffer with continuing severe hip pain.
