Platelet-rich plasma (PRP) therapy accelerates healing in knee surgery by delivering growth factors to repair ligaments, menisci, and cartilage. This regenerative medicine approach enhances tissue regeneration and restores knee function.
Area of Science:
- Orthopaedic Surgery
- Sports Medicine
- Regenerative Medicine
Background:
- The knee joint is vital in orthopaedics and sports medicine.
- Restoring knee function and preventing osteoarthritis requires reconstructing damaged joint elements.
- Platelet-rich plasma (PRP) products have gained prominence in regenerative medicine for tissue healing.
Purpose of the Study:
- To describe the application of autologous blood-derived platelet-rich plasma (PRP) in orthopaedic knee surgery.
- To detail the use of PRP in reconstructing and repairing specific knee anatomical structures.
- To highlight PRP's role in ligament, meniscal, and chondral surgery.
Main Methods:
- Utilizing autologous blood-derived platelet-rich plasma (PRP) products.
- Applying PRP to mimic and accelerate tissue healing processes.
- Detailing surgical procedures for ligament, meniscal, and chondral repair using PRP.
Main Results:
- PRP facilitates the delivery of growth factors, cytokines, and adhesive proteins.
- PRP supports the reconstruction and repair of damaged knee structures.
- This biological engineering approach opens new perspectives in knee surgery.
Conclusions:
- PRP is an effective tool in regenerative medicine for knee surgery.
- PRP aids in the repair of ligaments, menisci, and chondral defects.
- The use of PRP enhances the restoration of knee function and prevention of degeneration.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
