Filter by:Acupuncture research in regards to PONV has been fairly well established, however, studies about perioperative pain control and acupuncture are a little more murky. In 2008, a meta analysis looked at randomized controlled studies and found that while acupuncture was shown to decrease pain, there were limitations including credible placebo or sham intervention, and thus, blinding. The main purpose of this feasibility trial is to determine whether or not adequate blinding is possible in the intraoperative setting with the patient sedated.
The purpose of this study is to evaluate the effect of the Össur Rebound dynamic ACL brace on knee kinematics evaluated using dynamic stereo X-ray (DSX) imaging during functional activities. Brace performance will be evaluated before and after ACL reconstruction.
Primary objective of the study is to evaluate efficacy of the surgical technique for ACL reconstruction using an osteoconductive scaffold, enlaced into the hamstring tendon autograft, compared to the traditional technique.
A prospective trial will be used to evaluate the efficacy of prophylactic mechanical perturbation training program. 24 female athletes who are regular participants in activities that involve cutting, pivoting, jumping, and lateral movements prior to injury who range in age from 15-30 year are eligible. Using a prospective risk stratification design, female athletes with knee abduction moment (KAM) > 25.25 Nm from drop jump motion analysis will be classified as high KAM and will receive 12 sessions of mechanically-driven perturbation training and female athletes with KAM < 25.25 Nm from drop jump motion analysis will be classified as normal KAM and only participate in baseline performance testing, followed 6 weeks later by another session of drop jump motion analysis and performance testing.
The purpose of this study is to asses functional biomechanical outcomes and patient reported outcome measures following single bundle ACL reconstruction (ACL-R) compared to single bundle ACL reconstruction and extra articular tenodesis (ACL-R+EAT).
Widening of the single tibial tunnel following ACL surgery with quadrupled hamstrings autograft may contribute to failure of the graft and/or present technical challenges secondary to bone loss in a revision setting (Getelman, 1999). As such, efforts should be made to minimize the incidence and magnitude of tibial tunnel widening without sacrificing the biomechanical properties of the graft construct. The purpose of this investigation is to examine the tibial tunnel widening relationship between bioabsorbable interference screws composed of poly-L-lactic acid (PLLA) alone and composite bioabsorbable interference screws composed of poly-L-lactic acid embedded with beta tricalcium phosphate (PLLA+TCP) utilized as tibial fixation devices. Specifically the study has the following objectives: 1) To quantify the extent of tibial tunnel enlargement at 3-, 6- and 12-months post ACL reconstruction with autogenous quadrupled hamstring graft; 2) To determine if the incorporation of beta tricalcium phosphate to the bioabsorbable interference screw alters the observed magnitude of tunnel widening; 3) To hypothesize mechanisms for any observed differences between tibial fixation devices; and 4) To correlate tibial tunnel widening with clinical outcome status. It is hypothesized that the PLLA+TCP bioabsorbable interference screw will not be associated with a reduction in tibial tunnel widening around the implant but rather between the implant and articular surface, compared to the PLLA alone screw. It is also hypothesized that there will be no effect of observed tunnel widening on clinical outcomes or graft failure rates.
Anterior cruciate ligament (ACL) tears are disabling injuries that place a significant burden on the athlete. Roughly 80% of these injuries are linked to a noncontact mechanism, with more than 70% of them occurring while landing from a jump. Female athletes are at higher risk of sustaining a noncontact ACL injury due to the higher number of risk factors that they possess compared to their male counterparts. Due to this statistic, ACL prevention programs have been developed over the past 15 years in attempt to reduce this risk among the female athletic population. These programs have been shown to reduce the rate of noncontact ACL injuries in females by correcting the risk factors associated with them. However, it remains unclear as to whether these positive results are solely due to the program or a higher exercise workload in its participants. The purpose of this study is to evaluate the effectiveness that an ACL prevention program has on modifying at-risk landing mechanics (associated with noncontact ACL injury) compared to a resistance training program of equal workload.
