Brief Summary:
The objective of this study is to evaluate the effect of autologous platelet concentrate on blood loss post-operative decrease of haemoglobin concentration wound healing complications range of motion pain reduction and outcome scores when used in total knee arthroplasty
Detailed Description:
The short-term functional recovery after a total knee arthroplasty TKA is largely dependent on initial wound healing Haematoma formation may lead to prolonged wound drainage and tissue necrosis1 which can have a negative effect on early range of motion post-operative pain and length of hospital stay In addition studies have suggested that prolonged wound drainage also leads to a higher infection rate
To decrease haematoma formation primary soft tissue homeostasis and adequate tissue repair are essential During the immediate reaction of tissue to injury haemostasis and inflammation occur Growth factors especially PDGF platelet derived growth factor and TGF-β transforming growth factor-beta play a crucial role in the biochemical cascade at the site of repair These growth factors are mostly derived from platelets They act as chemotactic agents for polymorphonuclear leucocytes macrophages fibroblasts and lymphocytes Both factors stimulate angiogenesis and fibroplasia PDGF also has a role in wound contraction and remodeling When applying large concentrations of growth factors in a wound faster tissue repair and homeostasis can be expected thus leading to less haematoma formation
Treatment with autologous platelet concentrate involves direct application of concentrated platelets growth factors and fibrin in the operation wound A small volume 55-110 ml of the patients own blood is taken to derive a platelet rich gel which can be sprayed directly into the wound
