Overview
Brief Summary
The social impact of degenerative diseases such as articular cartilage pathology and osteoarthritis (OA) is steadily increasing, because of the continued rise in the mean age of the active population. A variety of noninvasive solutions have been proposed for pain treatment, improvement in function and disability, and ultimately, modification of the course of severe cartilage lesions and OA, with variable success rates. Intra articular and genicular nerves radiofrequency (RF) is a minimally invasive technique that usually aims at the neuropathic pain. One important mechanism for the chronic pain mediated by OA is peripheral sensitization, which increases the transmission of pain signals. Through conduction block in pain-transmitting nerve fibers by thermal damage, RF could ease pain without destroying the antennal nerve. The role of growth factors (GFs) in chondral repair is now widely investigated in vitro and in vivo.
Platelet-rich plasma (PRP) is a simple, low cost, and minimally invasive method that allows one to obtain from the blood a natural concentrate of autologous GFs.
Detailed Description
The aim of this study is to compare the efficacy of intra articular Platelet Rich Plasma (PRP) injection versus combined ultrasound guided intra articular and genicular nerve pulsed radiofrequency on chronic knee pain in patients with knee osteoarthritis. The regeneration capacity of cartilage is limited because of its isolation from systemic regulation and its lack of vessels and nerve supply. Osteoarthritis (OA) has a major impact on functioning and independence and ranks among the top 10 causes of disability worldwide

Outcomes
Primary Outcomes
Pain score
Time Frame: For 6 months after intervention
The intensity of pain at rest will be measured with a 10-cm visual analogue scale (VAS-pain). (VAS) identifying 0 as no pain and 10 as worst imaginable pain.
Secondary Outcomes
- Knee function(For 6 months after intervention)
- Patient satisfaction(For 6 months after intervention)
