..However, due to its variability among different individuals, comparison views of the contralateral extremity are warranted for confirmation of clinical suspicion of syndesmosis disruption...

..Real improvements in the outcome of TKA must address prevention of residual pain, stiffness and swelling, and each patient's preoperative concept of the likely outcome of these procedures...

..Cadaveric simulation of surgical procedures allows surgeons to measure variables affecting the technical success of surgery and to master new procedures without placing patients at risk...

..One should consider using the fibular strut allograft over the femoral ring allograft, as it is more stable and rigid construct in the immediate postoperative period...

..Utilization of this method of analysis and feedback in orthopaedic training is expected rapidly to enhance surgical skills without the risks of patient exposure...

..74). Biomechanical research on the effect of tibial tunnel dilation in hamstring fixation has not provided satisfactory evidence as to the benefits of this additional surgical step during anterior cruciate ligament (ACL) reconstruction...

..To investigate these effects, we developed an in vivo model of subchondral trauma...

..This study describes the results of computerized measurements of tibial inserts of one design known to be associated with a high prevalence of backside wear in situ...

....

..The purpose of this study was to determine the type and severity of backside wear in retrieved tibial inserts of several common total knee designs...

..9 months in vivo. The objective of this study was to identify factors contributing to surface damage of patellar components in total knee replacements...

..21 +/- 0.53 mm and 0.67 +/- 0.35 mm, respectively. A breach of the integrity of labral function is shown to lead to decreased femoral stability relative to the acetabulum during extreme ranges of motion...

..There was no clear evidence proving superiority and the need for posterior stabilization in PCL-sacrificing TKA...

..Proximal tibial coverage, even with a custom-fitted tibial component, adds little additional stability to a tibial tray stabilized by intramedullary engagement of a canal-filling stem...

..02). Repetitive impingement frequently occurs after total hip arthroplasty and leads to a multitude of adverse events, including motion between the liner and the acetabular shell...

..The custom-made brace overreduced the DRUJ in full pronation. Our results suggest that functional forearm bracing may be effective in reducing instability of the DRUJ without greatly restricting motion of the wrist, forearm, or elbow...

....

..Forty percent of TKAs at BMI > or =40 with patellar radiolucencies failed. In conclusion, TKA benefits were realized at all BMI, but at BMI > or =40, more rehabilitation and monitoring are recommended...

..By more clearly defining normal stability of the calcaneocuboid joint and its ligamentous contributions, greater insight into the diagnosis and treatment of calcaneocuboid instability can be obtained...

..To determine the accuracy and repeatability of an automated quantitative fluoroscopic imaging system for measuring knee laxity...

....

..CONCLUSION: Although the female endplates are smaller than their male counterparts, the overall shapes are similar...

..This construct was significantly (48%) stronger than dual medial and lateral plating...

..0001). Cracks commonly occur in conventional ultra-high-molecular-weight polyethylene liners, often after neck impingement and almost always in association with oxidation of the polymer...

..We examined the hypothesis that torsional maneuvers of the morphologically normal hip joint generate mechanical strain within the acetabular labrum, particularly in areas that are prone to injury...

..Clinical Relevance: Use of the central four-quadrant sleeve and screw system offers increased strength of fixation in anterior cruciate ligament reconstruction with hamstring tendon graft...

..6 N). CONCLUSIONS: Suture techniques were stronger at all levels of testing. CLINICAL RELEVANCE: Knowledge of biomechanical characteristics aids the surgeon in choosing the appropriate technique for each situation...

..The current study was designed to assess the security of arthroscopic knots under stepwise cyclic loading...

..Patients may benefit from therapies that reduce infiltration of inflammatory leukocytes into acutely injured cartilage...

..This may be related to the efficacy of the procedure itself or to differences in the severity of disability of male and female patients at the time of surgery...

..There are no studies that compare the articular morphology of potential donor sites on the distal femur with recipient sites on the talus...

..05). All ultimate failures occurred at the labral-implant interface. CONCLUSION: Initial fixation strength of tissue tack and suture anchor repairs of SLAP lesions are comparable...

..Urinary NTx concentrations followed a skewed distribution. Normalized NTx concentrations were statistically significantly greater in the celecoxib group than the placebo group at 6 weeks but not at 12 weeks...

..Electromagnetic computer-assisted surgery (EM-CAS) can be affected by various metallic or ferromagnetic factors...

..The results demonstrate that the proposed fiber Bragg grating sensor is a highly accurate, easily implantable, and minimally invasive method of measuring tendon and ligament displacement...
