Abstract
Partial patellectomy PP and reattachment of the patellar ligament with transosseous suturing is the mainstay of surgical treatment for distal pole patellar fractures An anchor suturing AS technique has recently been reported as an alternative to PP in such fractures and allows for bonetobone interface and possibly superior fracture healing than bonetotendon interface with PP We present our experience with AS and compare it to PPBetween 2006 and 2011 60 patients with distal pole patellar fracture underwent either AS n = 27 or PP n = 33 We retrospectively gathered their demographic data and information on fracture type fixation technique operation time postoperative complications and knee range of motion A telephone survey was performed to grade functional outcomes with standard questionnaires the SF12 for quality of life the Kujala score for patellofemoral function and a visual analog scale VAS pain scoreAS was equivalent to PP in terms of residual pain and functional outcomes VAS 245 vs 226 p = 083 and Kujala score 743 vs 69 p = 0351 respectively as well as for knee range of motion Complications included three cases of infection in each group two cases of early hardware failure and one case of nonunion in the AS group Operation time was significantly shorter for AS compared to PP 685 vs 791 min p = 003This article has been presented at the Orthopaedic Trauma Association Annual Meeting Tampa FL October 2014 in the 33rd Annual Meeting of the Israel Orthopaedic Association Tel Aviv November 2013 and will be presented at the 16th EFORT Congress Prague May 2015
