Masquelet technique combined with platelet-rich plasma to repair massive tibial defects / 中华创伤骨科杂志

ABSTRACT

Objective:To investigate the effect of Masquelet technique combined with platelet-rich plasma (PRP) on repair of massive tibial defects.Methods:A prospective randomized controlled single blind trial was conducted in the 21 patients who had been admitted to Department of Repair and Reconstruction Surgery, Foshan Hospital of Chinese Medicine for massive tibial defects from June 2016 to June 2018.The length of bone defects ranged from 6.0 to 22.5 cm (mean, 10.8 cm)in length.They were 14 males and 7 females, aged from 29 to 60 years(mean, 42.1 years).The patients were divided into 2 groups by an en-crypting envelope with a random digital table.In the experimental group of 11 cases, the bone defects were repaired with Masquelet technique combined with PRP; in the control group of 10 cases, the bone defects were reconstructed with only Masquelet technique.The 2 groups were compared in terms of operation time, hospital stay, wound healing, weight-bearing time, bony union time, clinical union time, complications and John-er-Wruhs scores at the second stage.Results:The 2 groups were comparable due to insignificant differ-ences between them in the preoperative general data ( P>0.05).All patients were followed up for 12 to 24 months (mean, 14.9 months).There were no significant differences in operation time, hospital stay, wound healing, weight-bearing time, Johner-Wruhs scores or rate of complications at the second stage between the 2 groups ( P>0.05).The bony union time (4.5 months ± 1.2 months) and clinical union time (4.1 months ± 0.9 months) in the experimental group were significantly shorter than those (5.7 months ± 1.5 months and 5.4 months ± 1.1 months) in the control group ( P<0.05).No such postoperative complications as infection, loosening of internal fixator, bone resorption or nonunion were found in the experimental group.One case of wound infection occurred in the control group but responded to dressing change. Conclusion:Masquelet technique combined with PRP is a safe and effective reparative treatment for massive tibial defects and can speed up bone healing.
