About this study
Official title: Combined Ultrasound Guided Genicular Nerve and Intra-articular Pulsed Radiofrequency Versus Intra-articular Platelet Rich Plasma Injection for Chronic Knee Osteoarthritis; A Comparative Study
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.
Read the 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
- Being tested
- Pulsed radiofrequency (P-RF), Platelet rich plasma (PRP)
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Pulsed radiofrequency (P-RF)Procedure or surgery
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
Platelet rich plasma (PRP)Procedure or surgery
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
| Study group | Role | What they receive |
|---|---|---|
| Pulsed radiofrequency (P-RF) | Placebo comparator | Patients will receive both intra articular RF and genicular nerve RF ablation Receives: Procedure: Pulsed radiofrequency (P-RF) |
| Platelet rich plasma (PRP) | Experimental | Patients will receive intra-articular platelet rich plasma (PRP) Receives: Procedure: Platelet rich plasma (PRP) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pain score
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.
Measured: For 6 months after intervention
Secondary outcomes (2)
Knee function
Subjective knee functionality will be evaluated using the Western Ontario and McMaster's Universities Osteoarthritis (WOMAC) Index.WOMAC Index assesses disability in three subscales, including pain, severity of physical function and joint stiffness. This scale consists of 24 items: five items for pain assessment, two items for assessment of the severity of joint stiffness and 17 items for assessment of physical function. The patient answers the questions and then receives a cumulative score in each of the 3 areas (pain, 0-20; stiffness, 0-8; physical function, 0-68). Higher scores are representative of greater pain and stiffness as well as worsened physical capability.
Measured: For 6 months after intervention
Patient satisfaction
Patient satisfaction when it comes to perceived improvement in symptoms after the treatment will evaluated using the Patient Global Impression Scale of Improvement (PGI-I) where; Very much better = 1, Much better = 2, A little better= 3, No change =4, A little worse=5, Much worse=6, Very much worse =7,
Measured: For 6 months after intervention
