Historical Perspective: Arthroscopic treatment of meniscal tears is one of the most common procedures performed by orthopaedic surgeons worldwide. The advent of newer technologies (suture materials, fixation devices, and biologic substances) has increased the potential for clinical success when attempting to repair the torn meniscus.
Indications and Contraindications: Classically, only peripheral meniscal tears were indicated for potential repair, and most tears were simply debrided. We know that preservation of the meniscus is critical to the continued healthy function of the injured knee. These newer technologies have made it possible for the clinician to consider repairing more meniscal tears than ever before.
Preoperative Planning: A thorough history and physical examination remains essential for preoperative planning before meniscal repair surgery. Standard radiographs and magnetic resonance imaging are also critical in determining tear location, morphology, and repairability.
Technique: Various surgical techniques (all-inside, inside-out, outside-in, and open) have all been discussed in the literature. Sutures and fixation devices can be augmented by a biologic adjuvant therapy, platelet-rich plasma (PRP).
Results: Clinical results using PRP to augment meniscal repairs has shown early clinical promise.
Complications: Reported complications related to the use of PRP have been minimal to nonexistent.
Postoperative Management: Routine meniscal repair rehabilitation protocols are followed when PRP is used to augment a meniscal repair.
