摘要:


文题释义:

富白细胞-血小板纤维蛋白凝胶:是自体富血小板与白细胞第二代纤维生物浓缩制品,通过二次离心抗凝自体血制备,质地致密,呈凝胶状,含有高浓度浓缩的生长因子和CD34+细胞,是一种自体血小板的浓缩物。
内侧髌股韧带:位于髌骨侧内缘的上2/3及股骨收肌结节与股骨内上髁之间的骨嵴上,是髌骨内侧的主要稳定结构,提供了抗髌骨外侧移位超过50%的力量。


背景:临床上创伤性髌骨脱位合并内侧髌股韧带股骨止点或体部撕裂多采用内侧髌股韧带重建手术,为促进内侧髌股韧带重建术后的腱骨愈合,研究者采用了包括生长因子、干细胞、富血小板血浆在内的多种生物治疗技术。

目的:探讨自体富白细胞-血小板纤维蛋白凝胶联合腘绳肌腱重建内侧髌股韧带修复创伤性髌骨脱位的临床疗效。
方法:选择2019年2月至2021年2月秦皇岛市第一医院诊治的创伤性髌骨脱位患者37例,采用随机数字表法分为试验组(n=18)与对照组(n=19),试验组接受自体富白细胞-血小板纤维蛋白凝胶联合自体腘绳肌腱重建内侧髌股韧带手术,对照组接受单纯自体绳肌腱重建内侧髌股韧带手术。两组患者术后随访12个月,通过目测类比评分、Lysholm 评分、Kujala髌股关节评分及膝关节活动度评估患者膝关节疼痛及功能状态,通过MRI及CT片测量髌股关节髌骨倾斜角、髌骨适合角及髌骨外移率,评估髌股关节的稳定性及改善情况。

结果与结论:①两组术后6,12个月的目测类比评分均低于术前(P < 0.05),术后6,12个月的Lysholm 评分、Kujala髌股关节评分均高于术前(P < 0.05);试验组术后6个月的Lysholm 评分、Kujala髌股关节评分高于对照组(P < 0.05),两组间术后12个月的目测类比评分、Lysholm 评分、Kujala髌股关节评分比较差异无显著性意义(P > 0.05);②两组术后12个月的髌股关节髌骨倾斜角、髌骨适合角、髌骨外移率及关节活动度测量值均较术前明显改善(P < 0.05);试验组术后12个月的髌骨倾斜角小于对照组(P < 0.05),两组间术后12个月的髌骨适合角、髌骨外移率及关节活动度及MRI评分比较差异无显著性意义(P > 0.05);③结果表明,自体富白细胞-血小板纤维蛋白凝胶联合腘绳肌腱重建内侧髌股韧带能有效治疗创伤性髌骨脱位,改善膝关节功能,恢复髌骨的运动轨迹。

Abstract: BACKGROUND: Traumatic patellar dislocation with medial patellofemoral ligament tearing at femoral attachment or body is usually performed by medial patellofemoral ligament reconstruction surgery. To promote tendon bone healing after medial patellofemoral ligament reconstruction, the researchers used a variety of biological treatment technologies including growth factors, stem cells and platelet-rich plasma.
OBJECTIVE: To investigate the clinical effect of medial patellofemoral ligament reconstruction by leukocyte- and platelet-rich fibrin with autologous hamstring tendon for traumatic patellar dislocation. 
METHODS: Thirty-seven patients with traumatic patellar dislocation in First Hospital of Qinhuangdao from February 2019 to February 2021 were randomly divided into a trial group (n=18) and a control group (n=19). The trial group received medial patellofemoral ligament reconstruction by leukocyte- and platelet-rich fibrin with an autologous hamstring tendon. The control group received medial patellofemoral ligament reconstruction by a simple autologous hamstring tendon. Patients in the two groups were followed up for 12 months. Knee pain and functional status were evaluated by visual analog scale score, Lysholm score, Kujala patellofemoral joint score and knee range of motion. The patellar tilt angle, patellar congruence angle and patellar lateral shift rate of the patellofemoral joint were measured by MRI and CT films to evaluate the stability and improvement of the patellofemoral joint. 
RESULTS AND CONCLUSION: (1) The visual analog scale scores of the two groups at 6 and 12 months after operation were lower than those before operation (P < 0.05). The Lysholm score and Kujala patellofemoral joint score at 6 and 12 months after operation were higher than those before operation (P < 0.05). The Lysholm score and Kujala patellofemoral joint score in the trial group were higher than those in the control group 6 months after operation (P < 0.05). There was no significant difference between the two groups in the visual analog scale score, Lysholm score and Kujala patellofemoral joint score 12 months after operation (P > 0.05). (2) The patellar tilt angle, patellar congruence angle, patellar lateral shift rate and range of motion of the patellofemoral joint were significantly improved in both groups 12 months after operation (P < 0.05). The patellar tilt angle was smaller in the trial group than that in the control group 12 months after operation (P < 0.05). Patellar congruence angle, patellar lateral shift rate, range of motion and MRI score were not statistically significant between the two groups 12 months after operation (P > 0.05). (3) These results confirm that medial patellofemoral ligament reconstruction by leukocyte- and platelet-rich fibrin with autologous hamstring tendon can treat traumatic dislocation effectively, improve the function of the knee joint, and restore the movement track of the patella.
