Active clinical trials for "Anterior Cruciate Ligament Injuries"

Atrophy and weakness are ubiquitous after a ACL rupture and associated with a worsened long-term recovery of individual capacities, despite surgery and rehabilitation. Preoperative rehabilitation (prehab) is believed to prepare patients for surgery and post-operative rehabilitation. However, prehab programs are highly variable, and do not always aim to develop/maintain neuromuscular parameters. The purpose of this study is to assess the effects of a lower limb strengthening training program during prehab prior to ACL Surgery on lower limb structure and function.

An assessment of the effect of surgical anterior cruciate ligament (ACL) on thigh muscles is critical to the improvement of knee rehabilitation and preservation. However, if a large number of studies had rated surgical technics, giving high results level for ACL reconstruction (ACLR), muscle recovery is still conditioning functional success. Furthermore there is no consensus about criteria in return to sport. The aim of this exploratory study is to quantify the mechanisms of neuromuscular adaptation of muscle thigh after ACL surgery.

The anterior Cruciate Ligament (ACL) injuries rates in female handball are high, particularly among adolescents. Therefore, the primary purpose of this randomized control trial is to explore the effects of an 8-week ACL injury prevention program on muscle activation of the medial hamstring muscles during sidecutting in female handball players. Secondary aims are to evaluate if training effects are age-related (pre-adolescent: 11-13 year old vs. adults: ≥18 years old). The age-related comparisons Include: Medial hamstring muscles activation during sidecutting; Well-known biomechanical ACL injury-risk factors during high risk movements, such as cutting and landing tasks; Cortical and muscular activity and functional connectivity patterns during controlled knee movements; Visuomotor skill learning during a simple task involving the hamstring muscles.

Surgery using the Arthrex PEEK or Biocomposite FastThread Interference Screw for ACL or PCL (PCL at US sites only, Biocomposite screw PCL only) repair or reconstruction.

Anterior cruciate ligament (ACL) reconstruction is one of most commonly performed orthopaedic surgeries. Several options for graft choice are available and autologous single bundle hamstring graft is most commonly used. Variability exists among patients in terms of hamstring size, and therefore the graft diameter. Recently there has been an increasing amount of literature correlating the hamstring graft diameter with the graft failure rate [1-4]. They concluded that graft exceeding 8mm in diameter is associated with a significant lower risk of graft failure. There has been study showing that Asian patients were indeed 'different' from the Caucasians. Ho et al published his findings on Singaporean patients showing that the median graft diameters for female and male patients were 7mm and 8mm respectively [5]. A retrospective review our patients undergoing ACL reconstruction in our department over the past 10 years has shown that the mean graft diameter was 7.8mm (range, 5.5-10mm). The conventional way of four-strand hamstring autograft is done by doubling both the semitendinosus and gracilis tendons to provide a quadrupled graft. Several techniques have been described to increase the size of the hamstring graft. One of those is the -strand hamstring graft, in which the longer semitendinosus tendon is tripled with the shorter gracilis tendon doubled to produce a 5-strand configuration. We hypothesized that the 5-strand hamstring graft would provide a graft of significantly larger diameter than the conventional quadrupled autograft.

Comparison between ACL repair and ACL augmentation in symptomatic patients with partial ACL injury

To investigate the hypothesis that suture repair of a ruptured vkb, combined with a dynamic intraligamentary stabilization and microfracture of the femoral notch, results in at least equal effectiveness compared with an ACL reconstruction using autologous hamstring in terms of functional recovery one year postoperatively in terms of a patient self-reported outcome related to be able to conduct daily and sporting activities. Secondary, the evaluation of clinical outcomes, self-reported by the patient outcomes, osteoarthritis, rehabilitation time required for return to daily and sporting activities and levels of sporting activity which has returned in patients with status after an ACL rupture and suture repair augmented with a dynamic intraligamentary microfracture and stabilization of the femoral notch in comparison with an anterior cruciate ligament reconstruction with the ipsilateral hamstring graft.

This study aims to determine the feasibility of implementing a mental skills training intervention for adolescent athletes who tear their ACL and undergo ACL reconstruction surgery alongside receiving standard-of-care clinical treatment. The study will also determine if the mental skills coaching program has any effect on the psychological readiness of patients to return to sport after undergoing surgery and postoperative recovery and rehabilitation. If feasible and if the mental skills training program shows promising effect on athletes' confidence in returning to sport, a large-scale clinical trial can be explored to assess the relationship between mental skills' impact on readiness to return to sport, which could in turn provide evidence on the benefits of integrating mental skills directly into standard clinical care.

This study will assess the safety and early efficacy of a newly developed device, bridge-enhanced scaffold (MIACH™,) used to repair a torn anterior cruciate ligament (ACL.) Ten participants will undergo surgery with the new device (Experimental Group) and 10 will undergo a standard ACL reconstruction surgery (Control Group.)

The aim of this multi-centered study is to evaluate the effects of two distinct Adductor Canal Block (ACB) adjuncts, dexamethasone and dexmedetomidine, and their combination, on postoperative analgesia in patients undergoing Anterior Cruciate Ligament (ACL) Repair.
