This clinical trial will evaluate the effectiveness of platelet-rich plasma (PRP) injections for patients with anterior cruciate ligament (ACL) injury. ACL injuries commonly cause knee instability, pain, and reduced function, and rehabilitation alone may not fully restore recovery in all patients. PRP is prepared from a small sample of the patient's own blood and contains natural growth factors that may promote healing and improve joint function.
In this study, participants will be randomly assigned to one of two groups. The experimental group will receive a single ultrasound-guided injection of PRP into the knee joint along with a standard rehabilitation program. The control group will receive the rehabilitation program alone.
Participants will be followed up at 3 weeks, 8 weeks, and 16 weeks after treatment. At each follow-up visit, knee function, pain level, and physical performance will be assessed using validated outcome measures. The primary aim is to determine whether PRP provides additional benefit compared with rehabilitation alone in improving function and reducing symptoms in ACL-injured patients.
This study will provide new evidence about the role of PRP in ACL management, which may help guide future treatment decisions.
Patients of both sexes who are older than 18 years and younger than 50 years
3 or Less than 3-months history of knee injuries
ACL injury MRI Grade 1 (Low) and medium Grade 2 (Medium) grade
ACL injury associated with Grade 1 or 2 Posterior cruciate ligament (PCL) tear and/or Grade 1 or 2 meniscal tear
Patients who have had intra articular corticosteroid injections in the index knee during the last 12 weeks
Patients who are taking systemic steroid
Patients who are younger than 18 and older than 50 years
Those with a history of platelet disorders or on the therapeutic anticoagulant or anti platelet drugs
Parallel
PRP injection
Biological/VaccineUltrasound guided intraarticular PRP is given to the patient with partial ACL tear
conventional conservative method (physical therapy, functional bracing, lifestyle modification)
Other interventionconventional conservative method (physical therapy, functional bracing, lifestyle modification)
Visual Analog Scale (VAS ): Change in pain intensity measured by Visual Analog Scale
Pain intensity will be assessed using the Visual Analog Scale (0 = no pain, 10 = worst possible pain).
KOOS: Change in functional outcome measured by Knee Injury and Osteoarthritis Outcome Score (KOOS)
KOOS assesses five domains: pain, symptoms, activities of daily living, sport/recreation function, and knee-related quality of life.
