Filter by:Background Anterior cruciate ligament (ACL) injuries are one of the most common sporting injuries of the knee. ACL reconstruction (ACLR) has become one of the most common surgical procedures in an attempt to increase joint stability and facilitate athletes to return to sport (RTS). Although ACLR is considered a relatively successful procedure, dynamic control risk factors and strength and power deficits in the involved limb are still present after patients return to sport. Dynamic multi-plane, multi-joint actions such as jumping, landing, change of direction cutting, have been shown to be common mechanisms of injury for the ACL in field sports . Returning to multidirectional sports requires a proficiency and efficiency of movement when carrying out these tasks. There is a lack of standardized, objective criteria to accurately assess an athlete's ability to safely RTS. Therefore, there is a need for research that simultaneously analyses sport specific dynamic tasks (3D motion analysis) and muscular strength/power deficits that may explain poor outcomes following ACLR. This study aims to further investigate movement patterns, limb asymmetry and muscle strength deficit in patients post-surgery to identify risk factors for re-injury and criteria for RTS. The purpose of this study was to: 1. Analyse kinematic (movement descriptors) and kinetic (forces that cause movement) during sports specific dynamic tasks at different time-points (6 and 9 months) following ACLR. 2. To explore the association of those findings with those who re-injure, those who have persistent knee pain or with those who fail to return to sport. 3. To compare the ACLR participants with age and gender matched healthy multidirectional athletes. It is hypothesised that biomechanical analysis will identify clear risk factors for poor outcomes following ACLR. Analysis of ACLR athletes' biomechanics during sports specific tasks will aid in the identification of athletes who are not yet ready to return to sport and will inform the clinician of what must be targeted in specific rehabilitation protocols before return to sport is considered. Brief protocol Participants will be recruited from patients who are scheduled to undergo anterior cruciate ligament reconstruction at the Sports Surgery Clinic, Ireland. Healthy participants will be recruited from local multidirectional teams. Participation will be voluntary and after obtaining informed consent patients will be asked to complete pre-operative questionnaires to ascertain injury information, and the function of their knee. During surgery the surgeon will fill out an intra-operative questionnaire. Items recorded will include graft type, laxity, involvement of other ligamentous structures, type of femoral and tibial fixation, meniscal or chondral pathology. Biomechanical assessment takes place at 6 and 9 months post surgery for the ACL group while the healthy participants will be tested on one occasion. The 3D testing session will include capturing of jumping, landing, hopping and cutting mechanics through the use of three dimensional motion capture technology and force plates. Here reflective markers are placed on the skin at anatomical landmarks. These markers are picked up by the infrared cameras and tracked at 200 frames per second. Participants will make contact with a force plate with their foot on undertaking the movements. Force and marker data will be combined to calculate joint angles and moments. Participants will also perform a muscle strength test using equipment called an isokinetic dynamometer. Both the operated and non-operated limbs will be tested. Participants will also be asked to fill out validated questionnaires to monitor self reported knee function, their confidence in their knee and also collect data on any continuing adverse symptoms such as locking, giving way, swelling or pain. Participants will also be asked if and when they return to sport. Questionnaires will be administered to participants at pre-op, 3, 6, 9, 12, 24 months, 5 and 10 years post operatively.
The assess results of Anterior Cruciate Ligament (ACL) repair with the Ligamys® surgical technique versus standard technique. The aim of the study is to compare (laxity, instability, and safety) these two types of treatment by using a prospective, randomised multicenter analysis.
This study is to compare the maternal and neonatal outcomes in the patients with PPROM who are managed at home versus those managed at hospital, half the patients will be managed at home and the other half will be managed inpatient.
In this study we will examine patients who have undergone anterior cruciate and/or posterior cruciate ligament and/or multi ligaments reconstruction to determine the rate of re-injury, contralateral tear and functional outcomes at least two years after surgery.
Anterior cruciate ligament (ACR) rupture is a common lesion of sportsmen that leads to functional deficits which are difficult to overcome. To prevent from an unfavorable evolution, patients can either get a non-surgical treatment or an ACR surgery, which is very common. Knee functional performance level could impact on the postoperative outcome and it's of common knowledge that early re-education after an ACR rupture improves knee functioning. Patients with an ACR rupture enrolled in this study will be randomized either in an experimental group (with preoperative reeducation) or in a control group (without preoperative reeducation). Both groups will then have post-operative re-education (40 sessions) based on HAS recommendations. The main aim of this study is to assess the impact of preoperative re-education on knee functional performance 4 month after surgical reconstruction of an ACR. Secondary aims are to determine the impact of the 4-week preoperative re-education on knee functional performance after an ACR rupture, before surgery and 7 months after surgery. Functional performance, muscular strength, proprioception and anterior knee laxity will be measured at inclusion (V0), 4-5 days before surgery (V1), 4 month (V4M) and 7 months (V7M) after surgery. Lysholme-Tegner scoring and IKDC2000 questionnaire will be added to the previous assessments.
The overall aim of this project is to investigate the healing processes of human tendon after suturing a ruptured Achilles tendon, and more specifically to determine the optimal loading pattern of the tendon during the rehabilitation period to ensure complete and good recovery of tendon structure and function. The investigators hypothesize that restricting early weight bearing and only allowing for passive stretching in the early phase of tendon healing will ensure better tissue regeneration and thereby prevent chronic tendon elongation and improve tendon tissue recovery and the clinical outcome.
100 women divided into 3 groups: - Group I: included 50 women with preterm premature rupture of membranes (PPROM, n=50) with gestational age from 24 to 34 weeks. - Group II: included 25 term non-labor control (T-CTR, n=25) with gestational age from 37 to 41 weeks. - Group III: included 25 preterm non-labor control (P-CTR, n=25) with gestational age from 24 to 34 weeks.The myometrial thickness at 4 different sites9: a) The lower uterine segment (LUS): 2cm above the reflection of the full urinary bladder (b)The anterior wall: 1cm above the maternal umbilicus. (c)Fundus: by placing the scan probe perpendicularly above the uterine fundus so that the entire curvature of the uterus was visualized. (d)The posterior wall: through using the maternal abdominal aortic pulsation as an anatomic marker. At least 3 measurements were obtained at each site and averaged. The latency interval is determined in each of the 3 groups.
Premature rupture of membranes refers to the rupture of the fetal membranes prior to the onset of labor. Premature rupture of membranes is associated with a number of neonatal and maternal complications including an increased incidence of perinatal mortality and intra-amniotic infection. There is a need for improved diagnostic testing because of limitations of the current methods. PRO-MComplete is an immunochromatographic test that detects insulin growth factor binding protein 1 and alpha-fetoprotein in vaginal fluid as an indicator of membrane rupture.
This prospective, single centred cohort study evaluates the physiological course of the potentially novel biomarker PSP in pregnant women as well as its predictive role in the development of inflammatory complications during pregnancy.
The investigators assess in this study the sensitivity of Urea and Creatinine and that of Nitrazine test in vaginal wash after injecting saline in the vagina of patients with pre-labour rupture of membranes
