Plate and screw fixation of arthroscopically assisted tibial tuberosity osteotomy: technique and results.

ABSTRACT

INTRODUCTION: We describe a fixation technique for tibial tuberosity osteotomies (TTO) utilising a plate and screw construct which adheres to established principles of bone healing. We record and discuss the complication profile and benefits of this technique. METHOD: The technique is outlined, and thirty consecutive case of TTO fixed with this combination of plate and screws were analysed during a study period from January 2018 to October 2018. All patients were followed up clinically to 3 months post-operation for the purpose of identifying early complications of surgery. Radiographic series were reviewed at 2, 6 and 12 weeks post-operation for evidence of fracture, loss of position, hardware failure and union. RESULTS: All cases went on to clinical and radiographic union by 12 weeks. We identified one case of hardware failure, one case of superficial infection and one case of stiffness requiring manipulation. CONCLUSION: We have found this technique of plate and screw construct to be effective in arthroscopically assisted TTO fixation leading to consistent union without loss of position with a low complication profile.
