Observation of therapeutic effect of autologous platelet-rich plasma on joint injury / 中国输血杂志

【Objective】 To study the therapeutic effect of autologous platelet-rich plasma(PRP) on joint injury. 【Methods】 Selected patients with joint injury treated in the Department of Transfusion Medicine of General Hospital of Southern Theatre Command of PLA from 2019 to 2020 were enrolled as the research objects, including 5 patients with shoulder joint injury, 34 patients with knee joint injury and 9 patients with ankle joint injury. All patients were treated with PRP injection at the injury site. The functional score and VAS score before and after treatment were compared. 【Results】 After 6 months of treatment, the CMS score and VAS of 5 patients with shoulder joint injury after treatment were (83.00±5.39) and (1.60±0.40), better than those before treatment (60.00±7.58)and (4.20±0.49)(P<0.05); The Lysholm knee score and VAS of 34 patients with knee joint injury after treatment were (80.73±2.43) and (2.07±0.24), better than those before treatment(50.30±2.96) and (4.28±0.33) (P<0.05); The AOFAS Ankle Hindfoot Scale and VAS of 9 patients with ankle joint injury after treatment were (68.44±4.59) and (2.56±0.53), better than those before treatment (42.67±4.57) and (4.89±0.63) (P<0.05). 【Conclusion】 For common joint injury sites, the clinical effect of using PRP injection is significant, which can effectively relieve pain and improve motor function, which is worthy of clinical application.

PLATELET CONCENTRATES FOR PERIODONTAL REGENERATION

@#Platelet concentrates are derivatives of blood that aid in haemostasis and wound healing after periodontal regenerative procedures. Its ability to act as a natural scaffold of growth factors has gained significance in many surgical procedures. This narrative review discusses the different platelet concentrates, their centrifugation protocols, advantages and disadvantages and their application in periodontal regenerative procedures. An electronic search of PubMed or MEDLINE was conducted for relevant material from the published literature up to 2020. The key words looked for were “Platelet concentrates, Platelet rich plasma, Platelet rich fibrin and periodontal regeneration.” We have used the filters comparative human studies, animal studies, randomized controlled trials, case reports and systematic reviews. The searches were limited to articles in English language and articles describing platelet concentrates and its relation to periodontal regeneration were collected and used to prepare a concise review.
