Abstract
This comprehensive review delves into the emerging role of platelet-rich plasma (PRP) in accelerating bone healing. PRP, a blood-derived product rich in platelets and growth factors, has garnered attention for its regenerative potential. The review begins by defining PRP and providing a historical background, highlighting its significance in expediting bone healing. PRP's composition and preparation methods, including centrifugation techniques and commercial kits, are explored. Mechanistically, PRP operates by releasing growth factors, chemotaxis, and angiogenesis, elucidating its cellular effects. Applications in fracture healing and orthopaedic surgeries, such as joint arthroplasty and spinal fusion, are discussed, emphasising the promising outcomes in clinical trials. Safety considerations, patient selection criteria, and the need for PRP preparation and application standardisation are underscored. The review outlines ongoing research trends, potential technological advancements, and unexplored areas in paediatric applications and inflammatory bone disorders. The implications for clinical practice involve informed decision-making, optimised protocols, and interdisciplinary collaboration. In conclusion, the future of PRP in bone healing holds exciting prospects, with the potential for precision medicine, integration with emerging therapies, expanded applications, and enhanced technological innovations shaping its trajectory in orthopaedics and regenerative medicine.
