摘要距骨骨软骨损伤（OLT）是一种以踝关节疼痛为特征的足踝部疾病，可影响患者关节功能及生活质量，若处理不当，可造成远期踝关节炎，严重影响预后。采用非手术治疗OLT的疗效尚不确切。手术治疗仍是目前治疗OLT的主要手段，且手术方式多样，然而最佳手术方式尚无定论，同时，病变软骨清理后的再生修复亦是治疗难点。富血小板血浆（PRP）对软骨损伤具有较好的修复效果，现已逐渐应用于OLT的治疗，但PRP治疗OLT的技术与规范尚缺乏统一认识。因此，上海市第六人民医院国家骨科医学中心联合中国医师协会骨科医师分会足踝基础与矫形学组、中国医师协会运动医学医师分会足踝专业组及上海市医学会骨科专科分会足踝学组组织相关领域专家，制订《富血小板血浆治疗距骨骨软骨损伤专家共识（2023版）》，就PRP的制备及使用，PRP治疗OLT的适应证、禁忌证、方法及相关问题提出15条推荐意见，以规范PRP对OLT的治疗。

abstractsOsteochondral lesion of talus (OLT) is a foot and ankle disease characterized by ankle pain, which may impact the joint function and life quality. If managed improperly, it may lead to a further ankle arthritis, severely compromising the prognosis. The therapeutic effect of conservative treatment for OLT is still uncertain. Surgery is still the main treatment modality for OLT with various techniques. However, the optimized surgical technique is still inconclusive, furthermore, regeneration and repair of cartilage after debridement is also a great challenge for the treatment of OLT. Platelet-rich plasma (PRP) with good repair effect on cartilage injury is gradually applied in the treatment of OLT. However, there still lacks the unified understanding of the technique and specification of PRP for the treatment of OLT. Therefore, National Orthopedics Center of Shanghai Sixth People′s Hospital allied Foot Ankle Basic Research & Orthopedics Group, Chinese Association of Orthopedic Surgeons; Foot and Ankle Committee of Chinese Association of Sports Medicine Physicians; and Foot and Ankle Group of Orthopedic Specialized Branch of Shanghai Medical Association to organize related experts to formulate the Expert consensus on platelet- rich plasma treatment for osteochondral lesion of talus ( version2023). Fifteen recommendations were put forward upon PRP preparation, indications, contraindications and treatment methods of PRP for OLT, so as to standardize the PRP treatment for OLT.
