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

Conditions

• Chronic Knee Osteoarthritis

Interventions

Type	Name	Description
PROCEDURE	Pulsed radiofrequency (P-RF)	Intra articular RF Insertion of the RF cannula within the joint. The recommended parameters are a pulse width of 20 msec and a rate of 2 Hz at 42°C for 10min. Genicular nerve RF ablation. The RF probe will be placed. A 50 Hz-frequency sensorial stimulation will be applied with a threshold of \< 0.6 V
PROCEDURE	Platelet rich plasma (PRP)	Under ultrasound guidance while the patients in a sitting position. In total, 3 to 8 mL of PRP will be injected via the inta-articular route
