AIMS: The aims of this study were to determine the proportion of patients with outlier varus or valgus alignment in kinematically aligned total knee arthroplasty (TKA), whether those with outlier varus or valgus alignment have higher forces in the medial or lateral compartments of the knee than those with in-range alignment and whether measurements of the alignment of the limb, knee and components predict compartment forces. PATIENTS AND METHODS: The intra-operative forces in the medial and lateral compartments were measured with an instrumented tibial insert in 67 patients who underwent a kinematically aligned TKA during passive movement...

Malreduction of a distal fibular fracture can lead to degenerative changes in the ankle joint. Previous studies have shown that the selective use of various fibular reconstructive osteotomies may halt the progression of degenerative arthritis by restoring the normal tibiotalar contact area and decreasing the stresses on the articular cartilage. In this case report, we achieved alignment with restoration of the talocrural angle and Shenton's line of the ankle using a transfibular osteotomy and an allogeneic fresh-frozen femoral head graft to fill the resultant defect...

BACKGROUND: Quadriceps-sparing (QS) approach is considered to be the most minimally invasive surgery for total knee arthroplasty (TKA). We perform this meta-analysis to evaluate whether malalignment and malposition are more biased towards the QS approach compared to the traditional medial parapatellar (MP) approach, which is still controversial. METHODS: According to the PRISMA guidelines, a comprehensive search was conducted in the databases of PubMed, the Cochrane library, and Embase...

Total ankle arthroplasty (TAA) and ankle arthrodesis (AA) are complicated surgeries that carry a learning curve with them. Complications are an aspect of all surgeries that must be considered. Surgeons must be prepared to handle these complications. The most important things are early identification and treatment of these complications. Treating complications is a combination of medicines, conservative measures, and most importantly surgical intervention. Recent studies have shown a decrease in complications of TAA and AA over the past 10 years...

With total ankle arthroplasty, documented complications can be categorized chronologically into intraoperative, postoperative, and late complications. Factors such as patient selection, surgeon experience, implant features, and prosthetic device selection can influence functional outcomes as well as incidence of complications. Even with impeccable surgical technique and optimal patient selection, complications that require revision may still arise and the most common complications with revision solutions are discussed in this article...

Total ankle arthroplasty is a viable surgical technique for the treatment of end-stage degenerative joint disease. With continued advancement in prosthetic design, refined surgical techniques, and improved outcomes, the indications for total ankle replacement have expanded to include cases of increasing complexity. With meticulous preoperative planning and exacting execution, many frontal plane deformities and cases of avascular necrosis can now be successfully addressed at the time of prosthesis implantation or in a staged procedure...

REVIEW
Hani M Badahdah, Thomas Zgonis
Ankle arthrodiastasis provides an alternative surgical treatment of the mild to moderate posttraumatic ankle arthritis. Ankle arthrodesis or ankle implant arthroplasty is usually reserved for the end-stage ankle arthritis and after conservative treatment options have been implicated for a long period of time. Ankle joint destructive procedures are often considered for the older and less active population with strict selected surgical criteria and prolonged rehabilitation. In either ankle joint-sparing or ankle destructive procedures, lower extremity deformity correction will need to be addressed before or at the time of index surgery for the overall patient's successful outcome...

BACKGROUND: The purpose of this study was to analyze femoral shaft sagittal parameters in Chinese osteoarthritis (OA) patients undergoing total knee arthroplasty (TKA) and identify whether the parameters in the coronal plane could be predictors of those in the sagittal plane. METHODS: Standard long-standing anteroposterior and femoral lateral radiographs of 50 lower limbs in 50 Chinese OA patients were included. Sagittal femoral bowing angle (sFBA), angle between femoral distal anterior cortex axis and sagittal mechanical axis (DACSMA), angle between femoral distal anterior cortex axis and sagittal distal anatomic axis (DACSDAA), and angle between femoral sagittal mechanical axis and sagittal distal anatomic axis (SMADAA) were measured...

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) radiograph of the entire tibia, we identified the medial cortical line that runs parallel to the tibial anatomical axis and passes the medial tibial spine, and measured the point where the medial cortical line crosses between the medial malleolus and the lateral malleolus in the ankle joint...

Controversy remains regarding the use of arthroplasty versus arthrodesis in the surgical treatment of late-stage hallux rigidus. The purpose of our retrospective study was to report the long-term follow-up results of the metatarsal head resurfacing implant used for hemiarthroplasty. The patient assessments were conducted using the American Orthopaedic Foot and Ankle Society (AOFAS) metatarsophalangeal clinical rating system and a satisfaction questionnaire. A total of 59 consecutive implantations were performed from January 2005 to December 2009 at our institution...

INTRODUCTION: Although periprosthetic fractures of the femur have been well documented, insufficiency fractures following total hip arthroplasty (THA) have been rarely described. We report a case of an insufficiency fracture in the distal tibia and fibula that occurred after THA. CASE REPORT: A 54-year-old woman presented with severe pain in the bilateral hip joints and was diagnosed with end-stage osteoarthritis. She underwent THA on the right side. Although the postoperative course was uneventful, she suddenly experienced severe pain and swelling in the right leg without any history of trauma 22 weeks after the surgery...
