Recent studies report that as few as 44% of athletes undergoing ACL reconstruction were able to return to their prior level of competitive level of sports. Early return may predispose an individual to re-injury including graft re-tear, meniscal tears, chondral injuries, and contralateral knee injuries. Criteria governing clearance to return to sports after ACL reconstruction has been traditionally defined using time from surgery and one or two objective criteria, often solely isokinetic quad/hamstring strength. Several studies have suggested that historical criteria used to assess readiness to return to play (RTP) are insufficient in identifying individuals at risk of a re-injury. They advocate for additional functional and dynamic testing, which may better reflect the complex kinematics required in high level athletic competition. We previously developed a "Safe Return to Play Following ACL Reconstruction Checklist" based on a systematic review of the literature and expert survey. Seven objective measures were developed as part of the checklist. The checklist is performed by a certified physical therapist trained in these performance tests. The purpose of this study is to validate the utility of our "Return to Play Checklist" by evaluating our patients prospectively for return to play following ACL reconstruction by comparing a cohort of patient undergoing testing with the checklist versus "clinical judgement."
The overall aim of this multicenter RCT is to determine whether concomitant ALL reconstruction in children undergoing and ACL reconstruction will longitudinally result in a lower rate of graft failure than ACL reconstruction alone.
The study was a prospective observational study analysis of cases having complete ACL tear. Study conduct between January 2021 to December 2022. All the patients attending emergency or Out Patient Department (OPD) of those hospital with knee injury were evaluated for ACL tear. Patients who meet inclusion criteria and give consent for participation in the study will observe to 1 year. Patient in Arifin Achmad Hospital Pekanbaru will follow rehabilitation treatment and optional delayed reconstruction after 12 weeks, while patient in Gatot Subroto Army Hospital Jakarta will performed early reconstruction treatment. After taking informed consent, all subjects were provided a self-administered patient questionnaire containing International Knee Documentation Committee (IKDC) score, ACL-RSI, Lysholm and Tegner Activity Level (TAL) scores. These questionnaires will be measured at 0, 12, 24, and 48 weeks. Besides that, all subjects were provided EQ5D for measuring utility value. Clinical value of Lachman test, Pivot shift test will be performed. One independent orthopaedic surgeon will keep all records and evaluate the results. All cost for the treatment will be accounted.
Aim of the research project: The entire research project aims to investigate human peripheral joints (knee, foot & ankle, elbow, wrist & hand) by dynamic 4D radiographic imaging acquisition during real-time motion. Aim of the specific study on Patellofemoral pain syndrome (PFPS) patients: This study aims to investigate kinematics and motion changes pre and post physiotherapy intervention in patients with patellofemoral pain syndrome (PFPS) and compare them with a healthy control group. Aim of the specific study on patients undergoing ACL reconstruction: This study aims to investigate kinematics and motion changes pre and post-surgical intervention in patients with ACL injury that require surgical reconstruction and compare them with a healthy control group.
Anterior cruciate ligament (ACL) reconstruction is one of the most commonly performed surgeries amongst young orthopedic surgery patients. Optimal post-operative pain control helps to reduce the opioid burden and to improve the patient's experience. Regional anesthesia, such as the femoral nerve block (FNB) and adductor canal block (ACB), are commonly used for post-operative pain control after surgery. The ACB has replaced the FNB. This is because the ACB targets the femoral nerve, while avoiding the numbing effects on quadricep muscle strength that make it difficult to move the leg. Another form of pain control is local infiltration anesthesia (LIA), which directly blocks pain in the knee. Similar to the ACB, it avoids the numbing effects on the quadricep muscle.This can help improve patient safety and experience by reducing risks of falls and allowing the patient to move earlier. This can also be associated with decreased time in the hospital and decreased costs. Technically, it is less complex and can be done the shorter period of time. The purpose of this study is to refine the pain management technique following anterior cruciate ligament surgery. More specifically, the aim of this study is to evaluate the effects of LIA alone, and a LIA-ACB combination on post-operative pain and thigh muscle strength.
The purpose of this study is to look at the effects of bone density on lower extremity loading mechanics using Blood Flow Restriction (BFR) to provide the control group for bone health. Hypothesis: The BFR group will have decreased bone mineral loss and improved functional performance compared to control group.
In this study our objective is to compare two tibial ACL graft fixation systems in patients undergoing two different reconstructions technique (with simple and double bundle) in terms of tendon graft osteointegration, functionality and return to sports.
Currently the diagnosis of OA is based on radiographs and clinical findings, which is limited to detecting late-stage disease. There is a pressing, unmet clinical need for robust assessment of early changes in cartilage health. Towards this goal, extensive efforts are ongoing to develop quantitative MRI for cartilage matrix analysis. MR T1ρ and T2 relaxation times have shown to be promising imaging biomarkers for early cartilage degeneration and prediction of disease progression. However, many challenges remain to clinically applying these techniques, including lack of standardized acquisition and quantification methods, and long acquisition times. The study aims to develop novel, fast and reproducible MR T1ρ and T2 relaxation time imaging methods on MR systems from multiple vendors and establish a platform for standardization and cross validation of these measures as a tool for clinical trials using such techniques. Following method validation, patients at risk for osteoarthritis will be tested.
The study is a prospective randomized control trial consisting of subjects requiring ACL reconstruction with BTB autograft. Subjects were randomly divided into two groups following their inclusion in the study. One group underwent the normal ACL rehab protocol as determined by the participating surgeons. The study group underwent normal ACL rehab modified by use of a tourniquet for blood flow restriction during selected exercises.
This study will evaluate the efficacy of the Lake Effect Zero Degree Knee Splint brace in the postoperative period of ACL reconstruction to improve range of motion, specifically the achievement of terminal extension and time-to-achievement compared to the standard hinged knee brace. This will be directly measured with goniometric angle and heel-height measurements relative to the contralateral side. Other metrics will include standard, validated patient reported outcomes and requirements for additional interventions to treat extension deficits including, but not limited to, additional therapy, intraarticular injections, oral corticosteroids, manipulation under anesthesia, or arthroscopic arthrolysis.
