Effects of Platelet-Rich Fibrin in Patients With Anterior Cruciate Ligament Reconstruction

Effects of Platelet-Rich Fibrin on Knee Muscle Strength and Function in Patients With Anterior Cruciate Ligament Reconstruction

The study was conducted to investigate the effects of platelet-rich fibrin on knee stability, knee muscle strength and knee function in patients with ACL reconstruction. Thirty patients with ACL reconstruction were included to the study and randomly divided into two groups. Patients were assessed preoperative and at the postoperative 1-year.

The study was conducted yo investigate the effects of platelet-rich fibrin (PRF) on the knee stability and function in patients with anterior cruciate ligament (ACL) reconstruction. Thirty patients with ACL reconstruction were included to the study and randomly divided into two groups (PRF group and control group). Hamstring tendon autograft was used in all patients for the reconstruction of the teared ACL. A standardized postoperative rehabilitation program was applied to all patients. Patients' knee stability, knee muscle strength and knee function were assessed preoperatively and one-year postoperatively. Knee stability was assessed using KT-2000 Knee Arthrometer. Quadriceps femoris and hamstring muscle strength measurements were conducted with an isokinetic dynamometer at 60˚/sec and 180˚/sec angular velocities. One Leg Hop (OLH) and Y-Balance tests, and International Knee Documentation Committee (IKDC) were used to evaluate the knee function.

Inclusion Criteria:

• Being isolated ACL reconstruction,
• Being between the ages of 18-45 years,
• Performing sports recreationally or professionally

Exclusion Criteria:

• Having previous knee surgery,
• Having systematic disease,
• Having multiple ligament injury on the knee or additional cartilage injuries
