Role of Platelets Rich Plasma (PRP) on the Outcome of Zone II Flexor Tendon Repair and Proximal Interphalangeal Joint (PIPJ) Range of Motion

Abstract

Zone II flexor tendon repair remains a surgical challenge due to the complex anatomy in the region. In this zone, both the flexor digitorum profundus and flexor digitorum superficialis must glide within a synovial sheath through a series of fibro-osseous pulleys. Early mobilization following repair of flexor tendons accelerates healing and prevents formation of adhesions. However, overly strenuous early mobility puts the repair at risk for rupture, which usually occurs within the first 3 weeks. Therefore, enhancing the quality of repaired tendon is mandatory, which can be depend on biologic adjuvants for tendon healing. Objective: To study the effect of combination of PRP injection with physiotherapy in flexor tendon zone II injury on gliding and range of motion improvement. Patients and Methods: Type of Study: prospective interventional controlled clinical study. Study Setting: plastic, burn and maxillofacial surgery department, Ain shams university, Cairo, Egypt. Study Period: 6 months. Study population: patients with zone II flexor tendon injury. Results: We studied the effect of PRP on the outcome of zone II flexor tendon repair and the range of motion. Forty cases were included in our study and divided into 2 groups. Group I was injected with PRP group II without PRP injection. Results was measured as regard the total range of motion showing no significant change in the range of motion between the two groups. Conclusion: We studied the effect of PRP on the outcome of zone II flexor tendon repair and the range of motion. Forty cases were included in our study and divided into 2 groups. Group I was injected with PRP group II without PRP injection. Results was measured as regard the total range of motion showing no significant change in the range of motion between the two groups.
