Anterior cruciate ligament (ACL) injury is a prevailing problem among sports participants, especially in non-contact sports. Studies have reported that 70-84% of ACL injuries are non-contact in nature, and movements like changing in direction while running, cutting and pivoting on a planted foot have resulted in a majority of ACL injuries. Even after ACL reconstruction (ACLR) surgeries, study has reported a 30-50% prevalence of developing patellofemoral joint (PFJ) pain in 1-2 years post-operation. Whole body vibration (WBV) therapy has been gaining attention as an effective method of training in recent years. It has been proved to have a positive effect on improving muscle strength, muscle activities, muscle power and loading during drop jump. Though duration of WBV may differ according to the effect of interest, several studies have had positive results with a 8 week WBV therapy in increasing muscle strength, proprioception, and post-ACLR knee functions. Further investigation on the underlying mechanism and possible application are to be continued to explore more possibilities with the WBV therapy.
Patients between 14-60 years of age who will undergo an anterior cruciate ligament (ACL) reconstruction between Nov 1, 2021- Dec 31, 2023, will have their charts reviewed be approached in clinic when the surgery is scheduled regarding their participation in this study. At the time of consent, patients will be randomized to a group via a computerized randomization process, either the experimental hybrid remnant repair (HRR) or traditional ACL reconstruction with ACL stump debridement. Routine postoperative data will be collected at regularly scheduled post-operative and physical therapy appointments including range of motion, pain, patient-reported outcomes, return-to-sport tests, and proprioceptive data. Additionally, patients will be asked to undergo a post-operative MRI between 9 and 15 months following the date of their surgery. Radiologists reading the MRIs will be blinded to which group the patient is in. The primary outcome measure is graft incorporation between the two groups.
Anterior cruciate ligament reconstruction(ACLR) surgery accepts best choices which condicions are totaly ruptured ACL or partial ruputures when patients with high activity level. Rehabilitation after ACL is an indispensable element of treatment because ACL injury causes severe instability and early degenerative changes in the knee. Although there is no standard rehabilitation program after ACLR but the concept of "Functional Rehabilitation" is prefers nowadays which structred according to therapeutic goals, it is planned in three stages as early, mid-term and late-term. After the late-term goals are achieved safely and the individuals reach to needed criterias, the stage of returning to sports or activity is planned. Patients with an active life expectancy, the goal at the end of rehabilitation after ACLR is to return to activity or sports and to reach pre-injury performance. Most individuals fail to return to sports or activity after ACL due to long-term strength deficits, neuromuscular and biomechanical changes, knee instability, and early developing knee osteoarthritis. Addition to that; changes that affect both the knee joint and the whole body biomechanics occur even in individuals who successfully return to activity and sports after ACL. Although there are problems that affect the whole body by exceeding a single segment in rehabilitation after ACLR; there is no study using the myofascial chain exercises approach in the treatment of these problems. Hip, core or trunk stabilization exercises and neuromuscular trainings that include more than one body segment added to the ACLR program provides more positive effects on rehabilitation outcomes than regional applications. In this project, researches aim to investigate that the effectiveness of structured myofascial chain exercises training, which will be applied in the late period of rehabilitation after ACLR, on functionality, performance and participation.In project scope; After completing the early and mid-term rehabilitation after surgery, the volunteers who met the criteria for transition to late rehabilitation were divided into two groups; lower extremity exercise training will be given to the first group and myofascial chain exercise training will be given to the second group. The control group will consist of healthy volunteers. In addition to the control group; The operated and intact extremities of the volunteers in the experimental groups will be compared. The training session, in which preterm and postterm evaluations and the exercises are taught, will be carried out with the face-to-face method, and the ongoing exercise sessions will be carried out with the telerehabilitation method. Reasearch outcome measures will be evaluated with strength, flexibility, balance, endurance, activity performance against time measurements and self-assessment questionnaires. End of this project; important data will be obtained in the fight against the risks created by the deficits that continue after the ACLR. The deficits seen after ACL fails to individuals from returning to their pre-injury functional level; the desired success cannot be achieved in returning to work, returning to sports, and returning to activity. Due to this situation, which poses a global problem, even if there is a return to work or sports after injury, branch and job changes may be required and the desired level of performance cannot be achieved. In individuals who cannot return to activity, inactive life increases the risk of non-communicable chronic diseases as well as the increased risk of osteoarthritis. In case of success in the project, important information will be obtained in order to prevent both the quality of life and the cost of secondary health and social life problems associated with ACL injuries. The content of the program will be expanded to include other sports injuries by applying to follow-up projects for the registration of the method to be applied for the first time.
Anterior cruciate ligament (ACL) tears are diagnosed by combining the patient's history and physical examination but clinical tests (e.g., Lachman, anterior drawer, and pivot shift) are less accurate within the first three weeks of injury. The Lever sign is a clinical test that has shown to have comparable diagnostic accuracy regardless of the time since injury, but this test has not been subjected to a randomised clinical trial and diagnostic values may be overestimated. Imaging modalities (e.g., MRI) are utilised when clinical diagnosis is not clear but are expensive and delay diagnosis. Hand-held arthrometry is an instrument that can be used in the clinical setting to provide an immediate, objective measure of ACL laxity, but this device has not been adequately validated. The first aim of this study is to determine the accuracy of hand-held arthrometry for diagnosing ACL tears following acute injury. A reliable and valid device could reduce healthcare costs and expedite appropriate treatment, thereby improving the management of patients following knee injury. The second aim of this study is to determine the diagnostic accuracy of the Lever sign test using a more robust study design than previously employed in other studies.
Clinical and comparative evaluation of the results of autograft healing of the tendon of the semitendinus muscle in the tibial canal, after reconstruction of the anterior cruciate ligament of the knee joint, by the method of stabilization of the screw with a bioabsorbable method, with or without the use of autogenous spongiform bone grafts.
The purpose of this study is to investigate the association between time spent in moderate to vigorous physical activity and markers of cartilage metabolism in the years following anterior cruciate ligament reconstruction.
The purpose of this study is to assess if a zoledronic acid injection can alter the trajectory of joint degeneration following an acute anterior cruciate ligament (ACL) injury.
The purpose of this study is to compare the effects of a femoral nerve block vs. an adductor canal block on pain and quadriceps muscle strength for knee arthroscopy surgery.
Quadriceps muscle strength is one of the key determinants for patients to fulfill the Return-to-Play (RTP) criteria after an anterior cruciate ligament reconstruction (ACLR), in which the muscle size is directly linked to muscle strength. Quadriceps muscle atrophy is unavoidable after ACLR, but the rehabilitation program should increase quadriceps muscle mass. However, despite good rehabilitation compliance, some patient's progress is sub-par and fail to regain muscle mass. Quadriceps muscle atrophy can persist beyond the completion of the rehabilitation program in almost half the patients and the reason behind this is still unknown. This represents an area that requires significant investigation, as quadriceps muscle atrophy and weakness have been shown to be determinants of poor knee function, decreased performance in sports and increased risk of reinjury. Quadriceps muscle atrophy after ACLR is well documented. This can be due to a decreased ability to regain muscle mass with rehabilitation. Athletes are one of the high-risk groups for vitamin D insufficiencies. Vitamin D deficiency can potentially result in decreased hypertrophy when exercising the muscle, leading to a poorer outcome in rehabilitation. Vitamin D has long been recognized for its effect on musculoskeletal health. It can have a direct effect on muscle hypertrophy by acting on specific vitamin D receptors (VDRs) on myocytes, and sufficient or increased levels of vitamin D in patients have been found to correlate with an increase in the size, number, and strength of muscle fibres. Quadriceps muscle hypertrophy after ACLR is triggered by exercise training, facilitated by diet and a number of intrinsic factors. As the rehabilitation programs and diets are similar in patients with varying extents of quadriceps muscle atrophy, individual responses (intrinsic factors) to exercise training may account for the resulting persistent quadriceps muscle atrophy. In this study, the investigators hypothesize that the deficiency of vitamin D may contribute to persistent quadriceps atrophy and weakness. With a stringent double-blinded randomized-controlled-trial (RCT) research design, our proposal will then address the research questions: 'Does vitamin D supplements improve the vitamin D deficiency status in patients after ACL reconstruction?', and 'Does vitamin D supplements improve quadriceps muscle strength for patients after ACLR?'
