Brief summary
To evaluate the efficacy and safety of platelet rich plasma (PRP) in patients with coxarthrosis who don´t respond to treatment with NSAIDs, compared to treatment with hyaluronic acid (Hylan G-F 20).
Interventions
Platelet rich plasma (PRP) is a platelet concentrated obtained from autologous blood centrifugation. This concentration technique provides larger amounts of biologically active molecules, mainly growth factors that are responsible for tissue repair. PRP (platelet rich plasma) contains a higher concentration of platelets from baseline (150,000-350,000 / ul).
Hylan G-F 20 is a viscous, sterile and non-pyrogenic elasto fluid containing hylan. Hylans are byproducts from hyaluronate (hyaluronic acid sodium salt), consisting of repeating disaccharides of N-acetylglucosamine and sodium glucuronate. Hylan G-F 20 replaces and supplements the synovial fluid. It is effective at any stage of the joint pathology.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| EVA scale for pain measure. | Through study completion, an average of 1 year. | The patient assesses the sensation of pain following a horizontal visual analog scale (EVA) with values between 0 (no pain) and the value 100 (excruciating pain). The records taken are recorded in the medical record of the patient. |
| Harris Hip Score for pain, function and range of motion measure. | Through study completion, an average of 1 year. | It is a questionnaire developed to evaluate hip surgery or replacement. It is widely used for evaluation of hip disorders and treatment methods. |
| WOMAC questionnaire for pain, stiffness and joint mobility measure. | Through study completion, an average of 1 year. | It is a standardized questionnaire, widely used for assessment of both knee and hip osteoarthritis. It consists of five items for assessing pain (range 0-20), two items that assess the stiffness (range 0-8) and 17 items that evaluate the functionality of the joint (range 0-68). |
Other
| Measure | Time frame | Description |
|---|---|---|
| Adverse events. | Through study completion, an average of 1 year. | All adverse events (AEs) are recorded in the case report data from the time that the patient sign the informed consent, indicating the nature of adverse events and their description in both: the experimental group and the comparator. |
