Atlas-based knee osteophyte assessment with ultrasonography and radiography: relationship to arthroscopic degeneration of articular cartilage.

Objectives: To investigate intra- and inter-reader agreement of ultrasonography (US) and conventional radiography (CR) for the evaluation of osteophyte presence and size within the tibiofemoral joint. In addition, to correlate these findings with arthroscopic degeneration of the articular cartilage.

Method: Forty adult patients with knee pain were enrolled in this study.

Role and regulation of VEGF and its receptors 1 and 2 in the aseptic loosening of total hip implants.

It was hypothesized that vascular endothelial growth factor (VEGF) in fibroblasts participates in aseptic loosening of total hip replacement (THR) implants. Therefore, osteoarthritic (OA) samples (n = 11) were compared with synovial membrane-like interface tissues from revision THR (n = 10). VEGF-A and its receptors were stained using streptavidin-immunoperoxidase method.

[Osteoarthritis of the thumb and fingers].

Most commonly affected joints of the hand in osteoarthritis include the carpometacarpal joint of the thumb (CMC 1) and the distal (DIP) and proximal (PIP) interphalangeal joints. Ageing, female gender, genotype, heavy work causing pressure on the hands, and injuries predispose to osteoarthritis in the hand. The pain is likely to be due to secondary synovitis caused by molecules released from the joint cartilage.

Diagnostic performance of knee ultrasonography for detecting degenerative changes of articular cartilage.

Objective: To investigate the diagnostic performance of non-invasive knee ultrasonography (US) to detect degenerative changes of articular cartilage using arthroscopic grading as the gold standard.

Design: Forty adult patients referred to a knee arthroscopy because of knee pain were randomly selected for the study. Before the arthroscopy, knee US was performed and cartilage surfaces at medial and lateral femoral condyles as well as at intercondylar notch area (sulcus) were semi-quantitatively graded from US.
