Meniscal Tear
Conditions
Brief summary
There are no current or past RCT comparing biologic augments for meniscal repair. There is good data supporting both the use of BMVP of the intercondylar notch and intra-articular PRP injections for augmentation of meniscal repair. However, the effectiveness of these augmentation methods with respect to each other has never been investigated. The knowledge gained will allow us to potentially influence and adapt protocols to treat this particular patient population. Additionally, resources available at our institution provide a supportive framework with which to maintain contact with patients after hospital discharge. These key factors will allow us to perform a robust analysis of this population, to include outcomes measures of function as well as meniscal repair failure and reoperation rate. The proposed interventional aim to compare meniscal repair augmentation methods is novel, as the direct comparison of these outcome measures has not been previously described. Because of the known benefit of biologic augmentation of meniscal repair, the investigators hypothesize that the repair failure rate for both cohorts will be lower than the reported repair failure rate for isolated tears without biologic augmentation; the investigators also hypothesize that BMVP of the intercondylar notch will clinically be significantly better than intra-articular PRP injection. The basis behind this hypothesis is in vivo evidence as well as a small RCT supporting the use of BMVP as augmentation for meniscal repair procedures.
Interventions
OTHERBone marrow venting procedure (BMVP)
The BMVP involves creating small holes in a non-weight bearing area of the bone that does not have any important structures; the holes act as channels, which allow for flow of the participants own biologic products and stem cells from within the bone marrow.
The PRP group will have 40cc to 60cc (about 3 tablespoons) of blood drawn at the time of surgery. The blood sample will then be prepared in a centrifuge machine to collect a component of the blood called platelet rich plasma. Once appropriate concentrations of the PRP are confirmed, the PRP will be injected into the subject's knee prior to wound closure.
