Brief Summary:
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.
