Has platelet-rich plasma any role in partial tears of the anterior cruciate ligament? Prospective comparative study

Figure 2 Magnetic resonance images. A: Baseline magnetic resonance imaging (MRI) showed widening of anterior cruciate ligament (ACL) fibers with continuity of fibers (orange arrows). Total score of 4 points according to Van Meer’s classification; B: Six months after platelet-rich plasma injection, MRI showed an improvement in the signal intensity as well as tension of ACL fibers (orange arrows). Total score of 0 points according to Van Meer’s classification (MRI sequence: sagittal proton density weighted turbo spin echo).
