Assessment of Anterior Cruciate Ligament (ACL) Degeneratio Mucosa Treatment
Anterior Cruciate Ligament InjuriesAnterior Cruciate Ligament (ACL) Degeneratio Mucosa is a condition resulting from mucoid degeneration of ACL. Exact etiology is unknown, however ACL Degeneratio Mucosa impairs everyday functioning. In the literature there were some reports of treatment by ACL excision and subsequent reconstruction, however such treatment brings risk of deteriorated function. In this study the investigator will evaluate the technique of ACL "decompression" by the means of longitudinal incisions and evacuation of extrafibrous mucoid tissue.
Effect of Specific ACL Injury Prevention Training in Female Handball Players
ACL Injury PreventionThe 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.

WEakness and Atrophy: isoKinetic With Surface Electromyography Assessment in ACL Surgery
Anterior Cruciate Ligament InjuryMuscle WeaknessAn 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 Use of Five-strand Hamstring Autograft to Increase the Graft Size in Anterior Cruciate Ligament...
Anterior Cruciate Ligament InjuriesAnterior 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.

Acute Anterior Cruciate Ligament Rupture; RecOnsTruction Or Repair?
Anterior Cruciate Ligament InjuryTo 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.
Readiness Outcomes Affecting Return to Sport 2.0: An Intervention Feasibility & Pilot Study
ACL TearThis 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.
Bridge-Enhanced ACL Repair-Safety Study (BEAR Trial)
Anterior Cruciate Ligament InjuryAnterior Cruciate Ligament TearThis 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.)
