ABSTRACT
To elicit current practice and attitudes toward use of antibiotic-prophylaxis among TJA patients prior to dental procedures, a cross-sectional survey of practicing Canadian orthopaedic (OS) and dental surgeons (DS) was undertaken. Of respondents, 77% of OS and 71% of DS routinely prescribe antibiotic-prophylaxis, but while 63% of OS advocate lifelong use, only 22% of DS choose to do so (P<0.0001). Both groups nonetheless recognize the importance of treatment within 2-years post-TJA as per AAOS/ADA guidelines. However, greater duration of practice pointed to potential inadequacy of these guidelines based on reported experience with late-hematogenous infection post-TJA. While discrepancies in attitude toward antibiotic-prophylaxis between surgeon groups remain, both groups agreed that the evidence to support decision making regarding antibiotic-prophylaxis for TJA patients undergoing dental procedures remains inadequate.

Opening-wedge high tibial osteotomy is an increasingly performed procedure for treatment of varus gonarthrosis and correction of malalignment during meniscal transplantation or cartilage restoration. Precise preoperative planning and meticulous surgical technique are required to achieve an appropriate mechanical axis correction. We describe our technique of arthroscopic and computer-assisted high tibial osteotomy using commonly available total knee arthroplasty navigation software as an intraoperative goniometer. We believe that our technique, by providing intraoperative real-time guidance of the degree of correction that is accurate and reliable, represents a useful tool for the surgeon who uncommonly performs high tibial osteotomy.
