March 18, 2020 updated by: Shu-Fen Sun, Kaohsiung Veterans General Hospital.

Efficacy of a Single Crosslinked Hyaluronan (HYAJOINT Plus) Combined With a Single Platelet-rich Plasma (PRP) Versus a Single PRP for the Treatment of Knee Osteoarthritis: A Randomized-Controlled Trial

Intraarticular hyaluronan or platelet-rich plasma (PRP) is each effective in the treatment for knee osteoarthritis (OA). The efficacy of combined hyaluronan with PRP for knee OA remained unclear. This study aimed to investigate the efficacy of a single intraarticular hyaluronan (HYAJOINT Plus) combined with a single PRP versus a single intraarticular PRP in patients with knee OA.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Intraarticular HA or PRP has been used for knee OA for years. Combined HA and PRP has not been widely used for OA because of lack of clinical evidence. Based on in vitro and animal studies, combining HA and PRP may benefit from their dissimilar biological mechanisms for tissue repair and have potentials to synergistically promote cartilage regeneration, inhibit OA inflammation, modulate the disease process, and improve joint homeostasis in OA. Combination of HA and PRP has much potential for the treatment of OA, but the clinical evidence of this combination remains unclear. The purpose of this study was to investigate the efficacy and safety of combined a single crosslinked HA (HYAJOINT Plus) with a single PRP versus a single PRP alone in patients with knee OA.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
VAS pain score change from baseline
Time Frame: 1,3 and 6 months
. The patient rated the average severity of knee pain on knee movement over the previous week on a 0-100 mm VAS (0=no pain to 100=worst possible pain)
1,3 and 6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC, Likert Scale)
Time Frame: 1,3 and 6 months
a 24-item questionnaire with 3 subscales measuring pain, stiffness, and physical function. Total score is 96 and higher scores indicate worse outcomes.
1,3 and 6 months
Lequesne index
Time Frame: 1,3 and 6 months
used to assess severity of knee symptoms during the last week. It includes the measurement of pain, walking distance, and activities of daily living. Maximal score is 24 and higher scores represent worse function.
1,3 and 6 months
Single-leg stance test (SLS)
Time Frame: 1,3 and 6 months
done by raising one foot up without touching it to the supported lower extremity with target knee and maintain balance for as long as possible. Each participant performed 3 trials, and the best result of the 3 trials was recorded.
1,3 and 6 months
satisfaction
Time Frame: 1,3 and 6 months
Patients were asked to rate their treatment satisfaction compared to the preinjection condition, using a 100 mm VAS (0= completely dissatisfied, 100=completely satisfied).
1,3 and 6 months
consumption of analgesics
Time Frame: 1,3 and 6 months
Acetaminophen (500mg; maximum daily dose, 4 g) was the only rescue medication allowed for knee pain. Acetaminophen was not permitted during the 24-hour period prior to each study visit. Use of rescue medication during the study period was recorded in a patient diary.
1,3 and 6 months
