Maquet Osteotomy, Results

Abstract

Objectives:The objectives are to assess the results and to discuss the indications for Maquet osteotomy in patients with patellofemoral osteoarthritis.Methods:Retrospective study of a series of 32 patients (4 bilateral, that is to say, 36 knees) operated between March 1999 and October 2013 in " Arthroscopy Private Center ", 12 male and 20 female, average age 59 years with an average postoperative surgery outcomes of 53 months. The technique consists of an arthroscopic procedure to treat joint lesions and a tibial tuberosity osteotomy of 5 cm long, by embedding a 1cm subsequent graft taken from the same metaphysis and fixed with 2 screws.Results:All patients had significant improvement, evaluated with Kujala’s score (54 points preop to 86 points postop) and Guillamon Ferguson’s criteria (27.2 very good and 60.7 good). The complication rate was acceptable.Conclusion:The available technics are surgeries on proximal soft structures, osteotomies of tibial tuberosity and patellofemoral arthroplasty. Maquet osteotomy is an excellent procedure when the patient’s selection is right. Obtaining the graft from the same metaphysis simplified the procedure.
