Introduction and Objectives: The aim of this study was to assess the results seen in patients with fracture of the tibial plateau treated by closed reduction and osteosynthesis under arthroscopic control. It is also the aim of this study to vindicate the use of the arthroscopic technique.

Materials and Methods: We carried out a retrospective study of 17 patients with external tibial plateau fracture Shatzker type I, II and III, treated by reduction and percutaneous osteosynthesis under arthroscopic control. We performed a metaphysis fill with iliac crest graft material. We determined the incidence of associated intraarticular lesions. Mean follow-up was 27 months. We assessed range of mobility, pain (VAS), muscular force with an isokinetic test and joint status by means of the Rasmussen scale.

Results: Mean age was 38 years with a mean time to intervention of 8 days. We found associated intraarticular lesions in 8 cases, 7 meniscal ruptures and 1 ACL rupture. The mean range of mobility was 125°. The mean loss of force was 15% in comparison with the contralateral leg determined by isokinetic studies. Results were satisfactory in 85% of cases according to the Rasmussen scale.

Discussion and Conclusions: The treatment of fractures of the external tibial plateau, Schatzker type I – II – III by closed reduction under arthroscopic control makes it possible to diagnose and treat associated intraarticular lesions and obtain good to excellent functional results in most cases.
