The introduction of new materials and better implant coatings seems to provide the prerequisites for more intense physical activities after total joint arthroplasties of the lower extremity. Despite recent advances in implant design and materials, recommendations for sport after total joint arthroplasty have not been updated over the past 20 years. The introduction of modern uncemented fixation as well as highly cross-linked polyethylene into total hip arthroplasty allow for a more active life-style without an increased risk of loosening or complications...

Total knee arthroplasty (TKA) is a rewarding procedure in patients with hemophilia and end stage knee hemophilic arthropathy. However, this procedure might be associated with complications such as infection. There periprosthetic joint infection in patients with hemophilia is very well known, though we are not aware of any previous report on Brucella infection in this group of patients. Here, we reported a 28-year old man with Brucella infection of total knee replacement who initially underwent a conservative treatment followed bya two-stage revision...

REVIEW
David E Cummings, Francesco Rubino
Several bariatric operations originally designed to promote weight loss have been found to powerfully treat type 2 diabetes, causing remission in most cases, through diverse mechanisms additional to the secondary consequences of weight loss. These observations have prompted consideration of such operations as 'metabolic surgery', used expressly to treat diabetes, including among patients who are only mildly obese or merely overweight. Large, long-term observational studies consistently demonstrate that bariatric/metabolic surgery is associated with reductions in all cardiovascular risk factors, actual cardiovascular events, microvascular diabetes complications, cancer and death...

INTRODUCTION: Management of distal femur fractures above total knee arthroplasty (TKA) remains challenging. Two common surgical options are locked lateral plating (LLP) and distal femoral arthroplasty (DFR). Unfortunately, approximately 30-50% of patients may die within one year of injury, require further surgery, or not regain prior mobility performance. We compared 87 LLP to 53 DFR patients - to our knowledge the largest comparative study - focusing on 90- and 365-day mortality, mobility maintenance, and further surgery...

Mark A Klaassen, Jerry L Aikins
The cyclops lesion is a localized anterior arthrofibrosis most commonly seen following anterior cruciate ligament reconstruction. The lesion forms at the anterior cruciate ligament insertion creating a painful extension block between femoral intercondylar notch and tibial plateau. We present 2 cases (3 knees) in which cyclops lesions appeared atypically following bicruciate-retaining total knee replacement. Two lesions occurred in a single patient following bilateral knee replacement. One lesion occurred in an active sportswoman...

OBJECTIVE: On a population level, the incidence of knee prostheses (KP) has increased, but excess health care costs per patient, compared to matched controls without a KP, in the years surrounding these procedures and their determinants are largely unknown. We therefore aimed to provide estimates of age and sex-specific incidence of KPs, revision KPs, and prosthesis complications in patients with knee osteoarthritis (OA) and to determine excess health care costs in the years surrounding surgery compared with matched controls...

BACKGROUND: Endoprosthetic replacement has become the mainstream method of reconstruction after tumor resection around the knee for decades, but there is a lack of comprehensive review evaluating the implant outcomes. We performed a systematic review to analyze the implant survival and complication profiles of distal femoral replacement (DFR) and proximal tibial replacement (PTR) in adults, and to evaluate the effects of different fixation methods and hinge mechanisms. METHODS: A systematic review of 40 studies with 4748 DFR cases and 1713 PTR cases was performed after searching the PubMed and EMBASE databases...

Introduction: Total femur arthroplasty (TFA) is a rare salvage limb procedure which serves as an effective alternative to limb amputation. Most commonly, it is indicated for oncologic orthopedic cases, and very few cases of a purely traumatic history for TFA have been documented. The decision to perform this complex procedure involves paying careful attention to reconstructive needs and functional expectations of the patient. Alternatives to this procedure are quite detrimental and include hip disarticulation and above-the-knee amputation...

Haemophilia is an inherited haemorrhagic disease characterized by the lack of coagulative factors associated nowadays mostly to musculoskeletal complications, particularly severe secondary arthritis in specific joints. Recurrent traumatic or spontaneous joint bleeding, induce severe arthropathy at a young age that can be treated only by joint replacement. Total knee or hip arthroplasty in young subjects may fail earlier due to wear or infections and in the haemophilic population, this means bone loss, pseudo tumours and the need of revision or even limb salvage surgery...

Background and purpose - Fast-tracking shortens the length of the primary treatment period (length of stay, LOS) after total knee replacement (TKR). We evaluated the influence of the fast-track concept on the length of uninterrupted institutional care (LUIC) and other outcomes after TKR. Patients and methods - 4,256 TKRs performed in 4 hospitals between 2009-2010 and 2012-2013 were identified from the Finnish Hospital Discharge Register and the Finnish Arthroplasty Register. Hospitals were classified as fast track (Hospital A) and non-fast track (Hospitals B, C and D)...

The sensorimotor system is a complicated tool allowing for maintaining body balance and responding to changing environmental conditions to prevent injury. It is difficult to objectively assess the function of balance control mechanisms due to the multidimensional nature of the sensorimotor system and multitude of variables that may interfere with the measurement. The function of the sensorimotor system is considerably compromised in osteoarthritis, including gona-rthro-sis. The knee is the second most common location of osteoarthritis, after the hip, and total or partial replacement surgery of the knee joint represents the therapy of choice in advanced stages of the condition...

Background: In this era of modern medicine, there is an increase in life expectancy and thereby an ageing population. Among this group one of the most common neurological disorder is Parkinson disease and one of the most common operation done in elderly population is a total joint arthroplasty. But total joint arthroplasty in Parkinson disease is a relatively uncommon entity. There is sparse literature available with regards to total knee arthroplasty (TKA) in Parkinson disease. This review focusses on the necessity, complications and previous experiences on TKA in PD based on the literature available...

Limb sparing surgery in growing young patients with malignant tumors is difficult as invasion of the physis by the tumor or surgical resection through the metaphysis may cause significant limb discrepancy following surgery. At present, hinged tumor prosthesis or biological reconstructions are the main methods following tumor resection in these patients. The aim of the present study was to assess different procedures for the treatment of osteosarcoma around knee joints in immature patients. A retrospective study of 56 patients (<15 years old, open physis) who had been treated for osteosarcoma around the knee joint between January 2007 and December 2015 was performed...

BACKGROUND: Endoprosthetic replacement (EPR) is an option for management of massive bone loss resulting from infection around failed lower limb implants. The aim of this study is to determine the mid-term outcome of EPRs performed in the treatment of periprosthetic joint infection (PJI) and infected failed osteosyntheses around the hip and knee joint and identify factors that influence it. METHODS: We retrospectively reviewed all hip and knee EPRs performed between 2007 and 2014 for the management of chronic infection following complex arthroplasty or fracture fixation...

BACKGROUND: Simultaneous bilateral total knee arthroplasty (SBTKA) offers significant socioeconomic benefits. However, retrospective studies and public health data show increased mortality and morbidity rates in patients undergoing SBTKA compared with those undergoing unilateral TKA (UTKA), and there have been recommendations against the use of SBTKA. High-volume centers, which feature careful patient selection and fast-tracked surgery, continue to perform SBTKA and have published their results in favor of the procedure...

Total knee arthroplasty (TKA) is the most commonly performed joint replacement procedure in the United States and annual demand for primary TKA is expected to grow by 673% by 2030. The first part provides an overview of imaging modalities (radiographs, CT, MRI, ultrasound, and various nuclear medicine studies) and discusses their usefulness in the imaging evaluation of TKA. The second part focuses on evidence-based imaging and imaging-guided intervention algorithms for the workup of TKA and its complications, including routine follow-up, component wear, periprosthetic infection, aseptic loosening, granulomas/osteolysis, conventional and rotational instability, periprosthetic fracture, patellar complications, and a variety of periprosthetic soft tissue abnormalities...

We report two cases where a proximal humeral locking plate was used for the fixation of an extremely distal, type III peri-prosthetic femoral fractures in relation to a total knee replacement (TKR). In each case there was concern regarding the fixation that could be achieved using the available anatomic distal femoral plates due to the size and bone quality of distal fragment. The design of the Proximal Humeral Internal Locking System (PHILOS) allows nine 3.5-mm locking screws to be placed over a small area in multiple directions...

Periprosthetic joint infection (PJI) remains a serious complication following a total joint replacement.  Diagnosis and management of PJI is challenging for surgeons since there is no "gold standard". This challenging condition requires a coordinated management approach to achieve good patient outcomes. Further difficulties involve choosing the optimal method to treat the periprosthetic joint infection. In this article, it is stressed the role of the two-stage revision: implant removal, debridement and placement of an antibiotic spacer, and antibiotic therapy with cessation prior to reimplantation...

BACKGROUND: Minority patients are at higher risk for complications and readmissions after total hip and knee arthroplasty. They are also more likely to undergo joint replacement in lower volume centers, which is associated with poorer outcomes. It is unknown whether these disparities simply reflect disproportionate use of lower volume centers. This study evaluates the impact of hospital volume on racial differences in outcomes following joint replacement. METHODS: Patients who underwent total hip or knee arthroplasty between 2006 and 2013 in New York and Florida were identified through the Healthcare Cost and Utilization Project State Inpatient Databases...
