pulse lavage irrigation, introducing the cement under sufficient pressure to allow it to penetrate

pressure and reducing blood flow to the femoral head.5 Similar to corticosteroids

pressure is a function of both structural and dynamic anatomy. Numerous studies have been performed that confirm the anatomic and mechanical relationship with PF pathologies. Jungmann et al. associated trochlear dysplasia with PF cartilage degeneration by comparing trochlear depth and patellar cartilage volume

blood pressure, and hyperglycemia, it is recommended to space these injections at least

blood loss in the PAO group, as well as increased acetabular implant size and a more superolaterally positioned cup.59 Technical considerations in patients undergoing THA after PAO include the potential for native acetabular retroversion and abnormal proximal femoral anatomy either due to previous osteotomy or underlying dysplasia.60

blood supply to the skin between the two incisions, because vasculature will not cross the new scar and can only travel down the peninsula of skin. Acute angles between incisions should be avoided as well. If an incision is made over an old scar

blood transfusion and preoperative anemia.82 Hepatitis C The hepatitis C virus (HCV) is the most common chronic bloodborne infection in the United States, and it is estimated that 3.3% of patients undergoing TJA are chronically infected with HCV.104,105 Although these patients account for a small percentage

pressures were greater in females at 0 and 30 degrees of knee flexion.100 The need to better understand the efficacy of patellar resurfacing in females is further amplified by the fact that females may be at an increased risk for periprosthetic patellar fracture after

pressures, and remove associated inpatient costs. Given that patients are not being admitted overnight, the associated nursing, pharmacy, physiotherapy, and occupational therapy costs are not incurred. Several recent studies support cost savings with outpatient arthroplasty.13-15 Establishing patient selection criteria is the most critical aspect
