Filter by: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.
An observational prospective study with the aim to analyze the presence at 6 months of a specific composite IS (Medacta Mectascrew C) in the reconstructive treatment of ruptured ACL or PCL by means of an autograft or allograft.
Double-bundle Posterior Cruciate Ligament Reconstruction (DB-PCLR) is becoming increasingly used alternative to the single-bungle PCLR. While more technically challenging, it seems to better improve patients' outcomes. Therefore, outcomes of DB-PCLR will be assessed and reported.
To establish a III°PCL injury model on fresh cadaver knee specimens, and to define the pathological and anatomical connotation of III°PCL injury by using anatomical methods. To explore and establish combined reconstruction techniques, including PCL reconstruction combined with injury repair and reconstruction, and to explore the role of combined reconstruction techniques in maintaining knee stability through biomechanical experiments.
Investigating the biomechanics for the PCL ruptured or reconstructed patients during walking, jogging, cutting, jumping. To establish a knee joint biomechanical evaluation model to quantify and evaluate the plantar pressure information under dynamic load-bearing state after PCL fracture. Provide a precise basis for the biomechanical state of the knee, and establish a clinically practical automatic analysis of plantar pressure information and an expert diagnostic system.
