Purpose This study aims to identify the effectiveness of the medial cortical line for attaining a more accurate tibial component alignment in proximal tibial resection using an extramedullary alignment rod. Materials and Methods The study examined 100 cases of total knee arthroplasty performed from December 2013 to February 2014 in a retrospective manner. On a preoperative anteroposterior (AP...

BACKGROUND Radiographic landmarks for medial knee attachment sites during anatomic repairs or reconstructions are unknown. If identified, they could assist in the preoperative evaluation of structure location and allow for postoperative assessment of reconstruction tunnel placement. METHODS Radiopaque markers were implanted into the femoral and tibial attachments of the superficial medial col...

BACKGROUND We hypothesized that a number of clinical and radiologic parameters could influence the reducibility of varus deformity in total knee arthroplasty. The aim of this study was to identify the factors correlated with reducibility of varus deformity and predict more accurately the amount of medial soft tissue release required in varus deformity total knee arthroplasty. METHODS One hund...

BACKGROUND Patient-specific instruments have recently gained attention for ensuring the accuracy of osteotomy and correct alignment in total knee arthroplasty (TKA). We aimed to report our experience with TKA performed by using CT-based 3D model of cutting guides in our clinic. MATERIAL AND METHODS A total of 36 patients (mean age, 67.58±8.46 years; 24 females, 12 males) who underwent TKA with ...

Post-traumatic premature closure of the distal fibular growth plate is a rare entity leading to shortening of the lateral malleolus. We report on a 14-year old boy who presented with a 4-year history of worsening, diffuse discomfort and swelling of his left ankle, as well as fibular shortening and talar malreduction. He had sustained a distal tibial fracture 4 years earlier and had been treated...

We describe two cases of knee deformity in SDS patients surgically treated. In case n.1, because of a severe deformity, an osteotomy of the distal femur was performed by removing a lateral wedge and stabilizing with a staple, plus lateral tibial hemiepiphysiodesis. In case n. 2 first a medial hemiepiphysiodesis of the proximal tibia with Blount staples was performed. After 18 months the staples...

The influence of the tibial tuberosity conformation on cranial cruciate ligament (CrCl) rupture was evaluated and the size of the tibial tuberosity of healthy dogs (group H) was compared with dogs with CrCl rupture (group R) and dogs treated by tibial tuberosity advancement (TTA) (group T). The medio-lateral radiographs of 219 stifle joints were evaluated. Relative tibial tuberosity width (rTTW...

Background: Posterior tibial tendon insufficiency plays a large role in the pathogenesis of adult acquired flatfoot deformity (AAFD) in select patients. Transfer of the flexor digitorum longus is indicated to compensate for the loss of posterior tibial tendon function; however the role of resection of the degenerated posterior tibial tendon remains unclear. The aim of this study was to determin...

Patellofemoral instability is a common cause of anterior knee pain, especially in younger and more active patients. Treatment of instability varies considerably depending on the patient's symptoms as well as the cause of the instability. Lateral instability has a particularly broad spectrum of treatment algorithms including patellar taping, arthroscopy, lateral release, medial patellofemoral li...

PURPOSE The purpose of this study is to evaluate the effect of change in tibial posterior slope on contact force and ligament stress using finite element analysis. MATERIALS AND METHODS A 3-dimensional finite element model for total knee arthroplasty was developed by using a computed tomography scan. For validation, the tibial translations were compared with previous studies. The finite eleme...
