Bilateral total knee arthroplasty (BTKA) patients may require blood transfusion which has its risks. Anti-fibrinolytic drugs such as aprotinin, aminocaproic acid and tranexamic acid (TXA) have reduced transfusion requirements in major surgery. This retrospective audit was performed to assess effectiveness of TXA in reducing blood transfusion rate in single-stage sequential BTKA cases operated by a single surgeon. Records of 91 patients given TXA and 80 controls who were operated before 2012 and not given TXA were reviewed...

Since its inception, arthroscopic surgery has become widely adopted among orthopedic surgeons. It is therefore important to have an understanding of the basic principles of arthroscopy. Compared with open techniques, arthroscopic procedures are associated with smaller incisions, less structural damage, improved intra-articular visualization, less pain in the immediate postoperative period, and faster recovery for patients. Pump systems used for arthroscopic surgery have evolved over the years to provide improved intraoperative visualization...

Muscle atrophy after total knee arthroplasty (TKA) occurs at a rate of 1% per day for the first 2 wk. Our hypothesis is that tourniquet-induced ischemia-reperfusion injury occurring during TKA influences metabolism and may contribute to atrophy. Identifying pathways that are upregulated during this critical "14-d window" after surgery may help us delineate therapeutic approaches to avoid muscle loss.

Total knee arthroplasty (TKA) is the most common and cost-effective treatment for older adults with long-standing osteoarthritis. Projections indicate that nearly 3.5 million older adults will undergo this procedure annually by the year 2030. Thus, understanding the factors that lead to optimal outcomes is of great clinical interest. In the majority of cases, tourniquet is applied during surgery to maintain a clear surgical field, however, there is debate as to whether this intervention is completely benign...

A 23-year-old Afghan National Policeman sustained a right popliteal artery injury secondary to a ground-based blast. Initial treatment was an application of a tourniquet, and after triage at a local civilian hospital a shunt was placed, 3 hours after the initial injury, and then was transferred to Kabul for definitive care, 24 hours after injury. Extensive trauma to both legs precluded use of greater saphenous vein as a graft. To avoid an above-the-knee amputation, a branch of the internal iliac artery was harvested for grafting...
