Osteoarthritis (OA) is a disease of the synovial joint with synovial inflammation, capsular contracture, articular cartilage degradation, subchondral sclerosis and osteophyte formation contributing to pain and disability. Transcriptomic datasets have identified genetic loci in hip and knee OA demonstrating joint specificity. A limited number of studies have directly investigated transcriptional changes in shoulder OA. Further, gene expression patterns of periarticular tissues in OA have not been thoroughly investigated. This prospective case control series details transcriptomic expression of shoulder OA by analysing periarticular tissues in patients undergoing shoulder replacement for OA as correlated with a validated patient reported outcome measure of shoulder function, an increasing (clinically worsening) QuickDASH score. We then compared transcriptomic expression profiles in capsular tissue biopsies from the OA group (N=6) as compared to patients undergoing shoulder stabilisation for recurrent instability (the control group, N=26). Results indicated that top ranked genes associated with increasing QuickDASH score across all tissues involved inflammation and response to stress, namely interleukins, chemokines, complement components, nuclear response factors and immediate early response genes. Some of these genes were upregulated, and some downregulated, suggestive of a state of flux between inflammatory and anti-inflammatory signalling pathways. We have also described gene expression pathways in shoulder OA not previously identified in hip and knee OA, as well as novel genes involved in shoulder OA.

The attitudes of orthopaedic surgeons regarding radiology reporting is not well-described in the literature. We surveyed Orthopaedic Surgeons in Australia and New Zealand to assess if they routinely review formal radiology reports.

An anonymized, 14 question online survey was distributed to consultant surgeons of the Australian and New Zealand Orthopaedic Associations (AOA, NZOA). Two hundred respondents completed the survey (Total number of Fellows: 283 NZOA, 1185 AOA). 18.5% of respondents always reviewed the formal Radiology report, 44.5% most of the time, 35% sometimes and 2% never. By imaging modality, MRI reports were the most frequently reviewed (92%), followed by ultrasound (74%) and nuclear medicine (63%). Only 10% of surgeons consulted formal reports for plain radiography. 55% of surgeons were still likely to disagree with the MRI report, followed by 46% for plain radiography. In cases of disagreement, only 21% of surgeons would always contact the reporting radiologist. The majority of Surgeons (85.5%) think there should be more collaboration between the disciplines, although only 50.5% had regular attendance of a Radiologist at their departmental audit.

This survey reveals that the majority of orthopaedic surgeons are not routinely reading radiology reports. This points towards a need for further interdisciplinary collaboration. To our knowledge, this is the first survey directly assessing attitudes of orthopaedic surgeons towards radiology reports.
