IMPACT-Global: Prevalence, Clinical Predictors and Mortality Associated with COVID-19 in Hip Fracture Patients. An International Multicentre Study of 7,090 Patients
Description
This video transcript covers a presentation by Michael McNicholas on the complications associated with knee osteotomy and the techniques to mitigate risks during surgery. McNicholas discusses case reports that highlight issues like popliteal artery damage leading to severe pain and pseudoaneurysms following osteotomy procedures. He emphasizes the importance of careful anatomical consideration while performing the procedure, particularly regarding the neurovascular bundles.
The discussion includes recommendations for using absorbable bone grafts, noting their risks related to arterial occlusion, as well as the importance of being cautious about the placement of cuts at the knee joint to prevent damage to surrounding vessels. A technical focus on techniques such as the De Bastiani drilling method is also presented as a way to safely perform the osteotomy. McNicholas shares insights from both anatomical studies and cadaveric research to underscore the risks involved with knee flexion during surgery.
Furthermore, he introduces the concept of preoperative assessments, including imaging for mechanical axis determination to guide osteotomy planning. McNicholas concludes with a summary of essential guidelines and principles—dubbed the '5 P's'—for conducting a safe high tibial osteotomy (HTO), which include knee positioning, hinge point design, neurovascular protection, patience in correction, and appropriate surgical planning. The video ends with an invitation for audience engagement through feedback and further discussions on related topics.
