Identifying risk factors for inferior outcomes after anterior cruciate ligament reconstruction (ACLR) is important for prognosis and patient information. This study aimed to ascertain if BMI, pre-operative scores, demographic data and concomitant injuries in patients undergoing ACLR affected patient-reported functional outcomes. A prospective review collected data from a single surgeon series of 278 patients who underwent arthroscopic ACLR. BMI, age, gender, graft choice, pre-op Lysholm score, meniscal and chondral injuries were recorded. The Lysholm score, hop test and KT1000 were used to measure post-op functional outcome at one year. Multiple regression analysis was used to determine factors that predicted Lysholm scores at one year.Abstract
Objectives
Methods
To undertake a biomechanical study to determine the existence of any difference in the early tibial component fixation to bone, between two widely used techniques of cementation, which may confer an influence on implant survival. 20 tibial saw bones were prepared by standard methods using extramedullary instrumentation to receive a fixed bearingtibial component (PFC, DePuy). Under controlled laboratory conditions, thetibial trayswere implanted with CMW cement using either of the two following cementation techniques (10 implants in each group): Full cementation–application of cement to the undersurface of the tibial tray, the keel, the cut surface of the tibia and its stem hole. Surface cementation – application of cement only to the undersurface of thetibial tray and the cut surface of the tibia. 72 hours after implantation, the fixation of the cemented components was assessed by determining the load to failure under controlled tensile stresses (using an Instron Electro-mechanical tensile tester).Aim
