STUDY OF REPAIR ROLE OF PRP IN THE PATHOLOGY OF CELLULAR DISTRIBUTION, LIVE CELL FRACTION AND STAINING PATTERN OF JOINT CARTILAGE IN HIP OSTEOARTHRITIS

Osteoarthritis is common in elderly people of the world, which is due to cartilage destruction
and osteophyte formation in the joint and which induce chronic pain and disability. The PRP due to its
high level of growth factors can help the repair process of the diseased joints. In this study the
autogenous PRP have been used for treatment of experimentally induced osteoarthritis in the rabbits.
Material and Methods: Osteoarthritis was induced in the rabbits left knee by resection of the anterior
cruciate ligament under general anesthesia. Eight weeks post operation and development of
osteoarthritis signs, 0.5 ml PRP was injected into the diseased joint in the rabbits of the test group. The
control group did not receive any treatment. The rabbits were euthanized and histopathologic samples
were collected at 8, 12 and 16 weeks post operation.
Results: The histopathologic study in the control group showed; least live cells, worst cellular
arrangements and least articular cartilage stainable matrix showing advanced osteoarthritis. But in the
group received the PRP there was no sign of osteoarthritis.
Conclusion: The authogenous PRP due to its high level of growth factors is an effective source for
treatment of osteoarthritis
