Complications resulting from tracker pin-sites in computer navigated knee replacement surgery / Anna Thomas in Acta Orthopaedica Belgica, Vol.81/4 (Décembre 2015)

Public ISBD [article]  inActa Orthopaedica Belgica > Vol.81/4 (Décembre 2015) . - p.708-712 Titre : Complications resulting from tracker pin-sites in computer navigated knee replacement surgery Type de document : texte imprimé Auteurs : Anna Thomas ; Gopalakrishna Pemmaraju ; Gurpreet Nagra Année de publication : 2015 Article en page(s) : p.708-712 Langues : Anglais (eng) Résumé : Intra-osseous pin sites used in Computer Navigated knee Arthroplasty are known to cause complications including infection, neurovascular injury, thermal necrosis and peri-prosthetic fracture. Many studies have looked at ways of reducing these risks to improve results in computer-navigated surgery. We present our complication rates and techniques used to reduce complications in a retrospective study of 321 patients performed by a single surgeon in between 2009 and 2013. One patient was identified with a superficial pin site infection. No major complications were recorded during a mean follow up period of 31 months. Attention to detail in every aspect of pin insertion reduces the rates of both minor and major complications. In particular rates of peri-prosthetic fracture were shown to be lower when using a unicortical drilling technique compared with the use of bicortical drilling in other studies.

Outcomes of combined tibial tuberosity transfer and medial patellofemoral ligament reconstruction for recurrent patellar instability / Gopalakrishna Pemmaraju in Acta Orthopaedica Belgica, Vol.82/2 (June 2016)

Public ISBD [article]  inActa Orthopaedica Belgica > Vol.82/2 (June 2016) . - p. 365-371 Titre : Outcomes of combined tibial tuberosity transfer and medial patellofemoral ligament reconstruction for recurrent patellar instability Type de document : texte imprimé Auteurs : Gopalakrishna Pemmaraju ; James Bassett ; Raad Abbas ; [et al...] Année de publication : 2016 Article en page(s) : p. 365-371 Langues : Anglais (eng) Mots-clés : Patella  instabilité  ligament  chirugie  genou Résumé : Patellofemoral instability is multifactorial and is associated with pathomechanics secondary to anatomical variance. Surgical management of this problem must be tailored to each patient and a thorough clinical and radiological assessment of the anatomical alignment should be carried out pre-operatively. The aim of this study is to assess the role of medial patellofemoral ligament reconstruction combined with tibial tuberosity transfer in patients with increased tibial tuberosity to trochlear groove (TT-TG) distance. Twenty-four patients (27 knees) over 2-years were operated on by a single surgeon, with standardised post-operative rehabilitation and follow up. Mean follow up was 31-months. Two patients had problems with recurrent instability, 1 had a traumatic re-dislocation at 2 years and a total of 4 required further operation for complications. Mean post-operative Kujala scores were 87.4 (SD 9.8). Combined medial patellofemoral ligament reconstruction and tibial tuberosity transfer is an appropriate treatment for patients with increased TT-TG distance.
