The article discusses the highlights of the Annual Meetings of the Knee Society Symposium held in Boston, Massachusetts in October 2009. The meetings tackled various issues concerning knee surgery including the risk factors for patellar crepitus following total knee arthroplasty, the use of debridement and irrigation, and the analysis of synovial fluid.

Displays illustrating papers and graphic expositions not correlated with sessions have become an integral part of annual meetings of the Association of American Geographers. Exhibits at Cambridge, Massachusetts accented physical geography rather more and human geography rather less than has been the case in recent preceding years. In a number of cases comparable maps of physical and human phenomena were displayed side by side. This appears to indicate a pronounced interest in regional correspondence of phenomena.
