About this study
Official title: Clinical Outcomes of Platelet Rich Plasma Injection Versus Corticosteroid Injection for Baker's Cyst
This is a Prospective study with Randomized patients into either Ultrasound-guided Platelets-Rich-Plasma injection and Ultrasound guided Corticosteroid Injection, with 3 months and 6 months follow ups after aspiration at our institution. There will be 25 patients in each group, including any patient with symptomatic baker's cyst.
Read the detailed description
The treatment of Baker's Cysts are based on its presentation, asymptomatic cysts are currently managed conservatively, symptomatic cysts are treated with joint aspiration and Corticosteroid injection, which have shown according to literature a decrease of the cyst size in approximately two-thirds of patients within 2-7 days but only complete disappearance in approximately 7 %. Ultrasound guided cyst aspiration and Corticosteroid injection are also used with reduction of cyst's size with recurrence in 6 months of 19%. Surgical options to remove the cyst include, Open Resection with a recurrence of 50%, 25% of patients have motion limitation recurrence, 37% have wound healing problems or tense swelling of the calf and 75% of patients have joint pain lasting more than 2 days. Arthroscopic resection, with no recurrence in ultrasound performed 6 and 12 months after procedure, pain lasting more than 3 days in 28% of patients, mild hematoma in 7% of patients and 7% where converted into an open procedure
There is no study using ultrasound guided aspiration with platelet-rich-plasma injection (PRP). The rationale for the use of PRP is the belief that the additional platelets will exponentially increase the concentration and release of multiple growth and differentiation factors at the injury site to augment the natural healing process9. PRP does not have any described negative side effect due to the fact that is being prepared from subject's own blood, with no risk of allergy or cross infection, relatively easy for a practiced clinician, and reproducible.

| Study group | Role | What they receive |
|---|---|---|
| Platelets-Rich-Plasma Group | Experimental | Patients will be asked to stop taking any type of anti-inflammatory medication from 7 days before the procedure to 2 weeks after and fasting for 3 hours before the procedure. At the moment of the procedure, the radiology team will draw 60ml of venous blood from the patient, the blood will be processed with different components of the PRP kit and centrifuged in the SmartPrep PRP machine, to obtain the PRP. The patient is then scanned prone using a linear 14 or 9 megahertz (MHz) transducer. A 20 Gauge spinal needle is usually employed for purposes of aspiration. Sterile saline will be used to confirm needle placement in the cyst in lieu of lidocaine and then inject the PRP by the radiologist. Receives: Other: Platelets-Rich-Plasma |
| Corticosteroid group: | Active comparator | Patients will be asked to stop taking any kind of anti-inflammatory medication from 7 days before the procedure to 2 weeks after but fasting in this group won't be required. An ultrasound guided aspiration and triamcinolone (40 mg) diluted with lidocaine without epinephrine and ropivacaine will be used to anesthetize the tissues down to the cyst (including within the cyst for steroid injections). A compression bandage will be placed locally for 7 days. Investigators will monitor any side effect from the injection and treat the patients per standard care - this can include prescription of analgesics. Receives: Drug: Corticosteroid |
What is being measured
The primary outcome is the main question the study is designed to answer.
Outcome of Baker's Cysts With the Use of Platelets-Rich-Plasma Versus Corticosteroid
Outcome measure will be determined through the use of the Visual Analogue Score (VAS) and the Rauschning and Lindgren criteria which are used to clinically evaluate the presence of the popliteal cysts, pain, posterior sense of tension in the popliteal fossa and its clinical importance for range of motion reduction. The Knee Injury and Osteoarthritis Outcome Score (KOOS) will be used to assess short and long term outcome of knee related conditions.
Measured: 6 Months
Secondary outcomes (3)
Recurrence of Baker's Cysts Treated on Each Group
Outcome measure will be determined through the use of the Visual Analogue Score (VAS) and the Rauschning and Lindgren criteria which are used to clinically evaluate the presence of the popliteal cysts, pain, posterior sense of tension in the popliteal fossa and its clinical importance for range of motion reduction. The Knee Injury and Osteoarthritis Outcome Score (KOOS) will be used to assess short and long term outcome of knee related conditions.
Measured: 6 Months
Complications
All disease signs and symptoms experienced by the patient, as defined as an Adverse Event (AE), Treatment Emergent Adverse Event (TEAE), Serious Adverse Event (SAE), and Unexpected Adverse Device Effect (UADE), will be recorded from questionnaires during each study visit.
Measured: 6 Months
Side Effects
All disease signs and symptoms experienced by the patient, as defined as an Adverse Event (AE), Treatment Emergent Adverse Event (TEAE), Serious Adverse Event (SAE), and Unexpected Adverse Device Effect (UADE), will be recorded from questionnaires during each study visit.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Platelets-Rich-Plasma and Corticosteroid in people with Baker's Cyst, run by NYU Langone Health at 1 site in United States.
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 6 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: stopped early, as of the sponsor's last update on 18 Mar 2020. 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 United States. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 Mar 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Outcome of Baker's Cysts With the Use of Platelets-Rich-Plasma Versus Corticosteroid (time frame: 6 Months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02249377, which also lists 11 linked publications.
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 18 Mar 2020.
