Background: The anterior cruciate ligament(ACL) , one of the major ligaments in the knee joint which connects the posterior aspect of the lateral femoral condyle to the anterior intercondylar area of the tibia. It plays a crucial role in maintaining knee joint stability, preventing excessive rotation of the tibia, and controlling the angles of knee valgus and varus. Additionally, the ACL contains mechanoreceptors that contribute to proprioception input. Acute ACL injuries are characterized by joint effusion, instability, and reduced range of motion. In the chronic phase, instability and pain may occur during rotational and cutting movements. Currently, regenerative injection therapies such as high-concentration platelet-rich plasma (PRP)and bone marrow concentrate (BMC) are being explored for ACL repair. Studies have found that postoperative administration of high-concentration PRP significantly reduces pain and improves knee joint function for a duration of 3 to 6 months, but these effects are not sustained beyond 12 months. In addition, some research indicates that high-concentration PRP does not enhance graft healing or improve knee joint stability. Method: This is a single-institution, single-blind, observational study conducted by the rehabilitation department of a public hospital. The study aims to recruit 40 participants with anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) injuries. The treatment intervention is collaboratively determined by the physician and the participant during the clinic visit. Subsequently, a therapist, unaware of the treatment details, conducts baseline assessments, including basic information collection, balance testing, gait analysis, timed up and go test, muscle strength evaluation, and subjective knee assessment questionnaire. Additionally, a physician, blinded to the treatment content, employs ultrasound to assess ligament elasticity. Follow-up assessments are conducted for the same parameters two months later.
After rehabilitation completion, there remains large deficiencies between the operative (OP) and non-operative (NOP) limbs in lower-limb outcomes (e.g., size, strength, and function) and these deficits can persist for years. Therefore, further specialized training protocols, such as the ones in the present study, are required to determine if these deficits can be lessened. The proposed project will evaluate the effect of 8-weeks of single-leg and double-leg lower-body resistance training on musculoskeletal function in individuals with a previous anterior cruciate ligament (ACL) reconstruction (ACLR) in a randomized control trial. The study will recruit 30-40 males and females between 18-35 years of age that have undergone a previous ACLR. Participants will be randomized to either the single-leg/unilateral (UL) or double-leg/bilateral (BL) training groups. Training will occur three times per week for 8-weeks. The UL group will participate in exercises such as split squats, single-leg deadlifts, or single-leg squats. The BL group will utilize exercises such as double-leg squats, conventional deadlifts, and leg presses. One week prior to (PRE) and one week after (POST) the training program, all participants will undergo a testing battery. Musculoskeletal ultrasound will measure quadriceps and hamstrings muscle cross-sectional area (mCSA), fascicle length (FL), and pennation angle (PA) of both OP and NOP limbs. Strength will be assessed through maximal voluntary isometric contractions (MVIC) for the quadriceps and hamstrings, and one-repetition maximum tests for single-leg leg extensions, leg curls, and leg press. Lower-limb function will be assessed through single-leg and double-leg jumps on a dual force plate system for jump height, impulse, rate of force development, and peak force. Data will be analyzed via separate mixed-factorial analyses of variance for the within-subjects factor of leg (OP vs. NOP) and time (PRE vs. POST) and the between-subjects factor of biological sex (male vs. female) and group (UL vs. BL). Post-hoc analyses will include lower-order ANOVAs and t-tests as pairwise comparisons when significance is detected. Significance will be established at p≤0.05. The results of this study will assist practitioners, coaches, sport scientists, and most importantly, the athletes, in the development of post-rehabilitative strength training protocols designed to reduce between-limb discrepancies.
Anterior Cruciate Ligament Reconstruction with and without Lateral Extra-Articular Tenodesis between high demand patients
The purpose of this clinical study is to compare the outcomes of two surgical techniques for reconstruction of the anterior cruciate ligament (ACL) after a single, primary ACL rupture. The main question to be answered is: - Does less widening of the tibial tunnel occur when a bone/Platelet rich plasma (PrP) composite material is placed directly into the tibial tunnel after fixation of the implant (experimental group) compared to the same surgery without the use of the composite material (control group)? Participants will be randomized into one of the two groups and they will not know which group they belong to. After 12 months they will undergo CT, MRI, medical examination and functional knee testing. They will have a further medical examination and functional knee testing at 24 months. Patient Reported Outcomes will be collected before surgery, 6, 12 and 24 months after surgery.
The investigators aimed to compare the clinical results of primary repairs and Lateral Extraarticular Tenodesis applied with primary repairs in the treatment of proximal ACL tears.
Analysis of Radiological Features of Lateral Femoral Impaction Fracture (LFC-IF) / Lateral Femoral Notch Sign will be performed on MRIs of consecutive patients after anterior cruciate ligament (ACL) injuries and without ACL injuries.
Anterior cruciate ligament injuries are one of the most common sports knee injuries. Their effect on the knee joint can be detrimental with patients experiencing instability and progressive damage of the intraarticular structures. Therefore, anterior cruciate ligament reconstruction (ACLR) is often indicated. Multiple graft option exist, including autograft, allograft and xenograft tissues, with autografts being considered as a first-choice source of reconstructed ligament in most cases. Two most common harvested autografts are hamstring tendons (semitendinosus or semitendinosus and gracilis tendons; ST or STG) and patellar tendon with two bone blocks (bone - patellar tendon - bone; BPTB). However, in the recent literature there is an increasing trend towards use of quadriceps tendon autograft (QT). Multiple techniques of harvesting this graft were described, including both partial and complete thickness of the tendon. Another issue is whether bone block from the upper pole of the patella is harvested along with the soft tissues (quadriceps tendon bone graft, QTB). The aim of this study is to add to the body of knowledge concerning full-thickness quadriceps tendon-bone autograft (QTB) used in ACLR. The primary outcome consists of The International Knee Documentation Committee Questionnaire (IKDC), the Knee injury and Osteoarthritis Outcome Score (KOOS) and retear rate.
