Arthroscopy-assisted minimally invasive treatment of posterior tibial plateau fractures / 中华创伤骨科杂志

ABSTRACT

Objective To explore the therapeutic efficacy of arthroscopy-assisted minimally invasive treatment for posterior tibial plateau fractures.Methods From July 2010 to June 2014,10 posterior tibial plateau fractures were treated at our department by arthroscopy-assisted minimally invasive treatment with percutaneous lag screws.They were 8 men and 2 women,with a median age of 31 years (from 18 to 52 years).All the fractures were closed and fresh,including 3 posteromedial tibial plateau ones,5 posterolateral tibial plateau ones,and 2 posteromedial and posterolateral tibial plateau ones.They were followed up periodically by radiological examinations.At the final follow-up,their knee functions were evaluated by Rasmussen scoring system,and their pain was evaluated by the visual analogue scale(VAS).Subjective factors included swelling,stairs climbing,joint stability,job participation and satisfaction with recovery.Results The follow-ups averaged 18 months (from 12 to 24 months).All fractures healed within 3 months postoperatively,with no infection or serious complications like implant failure.At 12 months postoperation,the mean Rasmussen score was 26 points (from 19 to 30 points).Eight cases were rated as excellent,one as good,and one as fair.Their mean VAS score was 1.2 points (from 0 to 4 points).Conclusion Arthroscopy-assisted minimally invasive management of posterior tibial plateau fractures with cannulated screw fixation is feasible,because it results in limited invasion,satisfactory reduction,reliable fixation,quick functional recovery and a low rate of complications.
