About this study
Intraarticular injection (IAI) of Platelet rich plasma (PRP) with Hyaluronic acid (HA) Versus Radiofrequency (RF) of genicular nerve for pain reduction of of knee osteoarthritis , Improving daily activity and reduction analgesia requirements
Read the detailed description
In this study the investigators to comparing between the effect of Intra articular injection of hyaluronic acid (HA) with platelet rich plasma (PRP) versus genicular nerve thermal radiation in management of pain in knee osteoarthritis.
Knee assessment and pain score recorded according to Visual Analogue Scale (VAS) after one week, one month, three months, six months following intraarticular injection and radiation.
All analgesics stopped and only (Arcoxia "etoricoxib" 60 mg, 90 mg) was taken after the procedure, total day dose and frequency will be reported, other analgesics taken by the patient is reported also.
Improvement of daily activities and clinical examination for the studied knees is observed.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intra articular injection GroupDrug
Also called Intra articular injection of hyaluronic acid and platelet rich plasma
Patients included in the study had been received 2 ml high molecular weight (1.476 x 106 average Daltons) hyaluronic acid with concentration of 22mg/ml (OPTIVISC UK hyaluronic acid for intra articular injection). Platelet rich plasma is arranged by withdrawing 10 ml of patient's personal venous blood, anticoagulant is added, and centrifuged by duo-spin method, at the rate of 3500 rpm for five minutes then injected twice with 2 weeks interval. 3 distinct layers are produced by the end of the centrifugation: plasma, buffy coat (platelet) and RBCs, about 3 - 3.5 ml of PRP is produced
at the end with platelet concentration of 1.4 - 1.6 million/μl on average.
Radiofrequency GroupDevice
Also called Thermal radiation of Genicular nerve
Thermal radiation is done by Neurotherm 2000 (Neurotherm NT 2000 Radiofrequency (RF) Generator is a four electrode pain management (RF) generator for interventional pain management procedures. Neurotherm's newest system offers accurate independent controls of each electrode through the touch screen interface and output control knobs.), Patients from the radiofrequency (RF) group had been placed in the supine position and their knee will be supported by a small pillow placed beneath the popliteal fossa. Fluoroscopic images of knee joint had been obtained. Possible locations of genicular nerves had been determined on the lateral, medial aspects of the lower end of the femoral bone and on the medial aspect of the tibia, under fluoroscopic guidance.

What is being measured
The primary outcome is the main question the study is designed to answer.
Pain Measurment via Visual analogue score
Visual analogue score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-10. A higher score indicates greater pain intensity was measured throuout 6 months follow up session
Measured: Measured throuout 6 months follow up session
Secondary outcomes (2)
Analgesic requirements Comparison
Compairing between analgesia requirements in Rf group and IAI group
Measured: Throuout 6 months follow up session
Improvement of daily activities between 2 groups
Compairing between analgesia requirements in Rf group and IAI group

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Intra articular injection Group and Radiofrequency Group in people with Knee Osteoarthritis, run by Cairo University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pain Measurment via Visual analogue score (time frame: Measured throuout 6 months follow up session). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Dec 2019; AzTrials last refreshed its copy on 7 Nov 2026.
