About this study

Official title: "Effect of Intraoperative Application of Autologous PRP on Post Operative Morbidity in ACL Reconstruction Using Autologous Bone Patellar Tendon Bone Graft Harvest"

The purpose of this research study is to investigate whether or not platelet rich plasma (PRP) may help to improve tendon healing and decrease post operative pain in patients undergoing anterior cruciate ligament (ACL) reconstructive surgery using their own patellar tendons as autografts.

Read the detailed description

There is currently a paucity of well-designed, prospective, randomized, blinded (Level 1) clinical studies that carefully and comprehensively investigate the role of PRP in ACL surgery. Specifically, ACL reconstruction using Bone Patellar Tendon Bone (BPTB) harvest and the role of PRP in decreasing postoperative pain at the donor site. Given the need for a highly powered study to demonstrate the clinical efficacy of PRP in ACL reconstruction, the investigators have designed a prospective, randomized, level 1, double-blinded study to evaluate the effects of PRP on the specific outcomes of donor site pain and radiographic measures of graft healing and incorporation.

The aim of this study is to evaluate the efficacy of intra-operatively applied autologous PRP in reducing donor site morbidity and increasing radiographic healing in ACL reconstruction using autologous BPTB.

Study groups in NCT01765712
Study groupRoleWhat they receive
Control GroupPlacebo comparatorPatients will be randomized into the treatment arm using a computer generated randomization table (simple randomization). Patients in the control arm of the study will undergo Anterior cruciate ligament reconstruction using Autologous bone patellar tendon bone autograft. At the end of the surgery, their graft donor site will have bone graft chips placed into the bony defect and the wound will be closed using sutures.
Receives: Procedure: Anterior Cruciate ligament reconstruction bone patellar tendon bone autograft
Platelet Rich PlasmaExperimentalPatients randomized into the treatment arm of the study will undergo Anterior cruciate ligament reconstruction with Autologous bone patellar tendon bone autografts. At the start of the surgery,just after the administration of anesthesia, 10cc of blood will be withdrawn from the patients IV by the anesthesiologist. This sample will be spun down into 3-5cc of Platelet Rich Plasma which will be added to the patients bone graft chips and placed into the donor site at the end of the case.
Receives: Procedure: Anterior Cruciate ligament reconstruction bone patellar tendon bone autograft; Biological: Platelet Rich Plasma

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Anterior Knee Pain

    The primary outcome measured will be anterior knee pain. The investigators will do so by using Visual Analog Scales as an assessment tool. The visual analog scales will include pain with activities of daily living and pain with kneeling activities. Information regarding these pain scales will be collected at 14 days and 1,3,6,12,18 and 24 months. The Visual analog Scale is a score from 0-10 with 0=no pain and 10=excruciating pain.

    Measured: 2 weeks, 1, 3, 6, 12, 18, 24 months. Kneeling pain for treatment groups at 24 months post-op reported.

Secondary outcomes (4)
  1. Radiographic Assessment of Tunnel Positioning

    A triple view radiographic series of the knee will be performed to assess the position of the tibial and femoral tunnels by one blinded senior radiologist.

    Measured: 3 months

  2. Quantification of Healing at the Bony and Tendinous Harvest Sites

    Post-op MRI's will be obtained to quantify the amount of bony healing at the donor site and revascularization of native patellar tendon at the harvest site. These images will be interpreted by one blinded senior musculoskeletal radiologist.

    Measured: 6 months

  3. Post Operative Strength

    The objective clinical assessment of strength in the operative extremity will measured as quadriceps strength in a single leg hop test. This data will be collected by an independent researcher also blinded to treatment.

    Measured: 3,6,12,18,24months

  4. Post Operative Range of Motion

    The patients range of motion will be assessed on both the operative and non-operative knee. This information will be assessed using a goniometer and will be collected by a blinded clinician.

    Measured: 2 weeks, 1,3,6,12,18,24months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Anterior Cruciate ligament reconstruction bone patellar tendon bone autograft and Platelet Rich Plasma in people with Post Operative Pain, run by Brian Walters 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 5 inclusion and 8 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 24 Mar 2021. 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. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 24 Mar 2021). 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?

Anterior Knee Pain (time frame: 2 weeks, 1, 3, 6, 12, 18, 24 months. Kneeling pain for treatment groups at 24 months post-op reported.). 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 NCT01765712, which also lists 1 linked publication.

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 24 Mar 2021.
