The themes of this paper are the clinical relevance and technique of perioperative management in total knee arthroplasty. Due to the number of unsatisfied patients after knee arthroplasty, optimisation of processes seems to be necessary. Beside patient preparation and rehabilitation, the surgical technique and implant choice in perioperative management are important. This means the use of tourniquet and drains, the application of tranexamic acid and pain management. These items are presented and discussed in detail in this paper...

Background Large bone defects and losses play a crucial role in both tumour surgery and in complex primary and revision total knee replacement. The established options of cemented or uncemented long intramedullary stems are limited by large bone defects and are at risk from relatively high exposure to aseptic loosening. There is no general valid agreement on implant fixation of the distal femur. A further option is the cementless fixation method with compressive osseointegration, based on the so-called Wolff law of bone remodelling...

REVIEW
Luigi Piero Solimeno, Gianluigi Pasta
Today, major surgical procedures can be safely performed in hemophilic patients with chronic arthropathy, using available factor concentrates. In this setting, total knee replacement is considered the "gold standard", while the use of total ankle replacement is still debated. Indeed, the unsatisfactory results obtained with the previous available design of implants did not raise enthusiasm as knee or hip replacement. Recently, the introduction of new implant designs and better reported outcomes have renewed the interest in total ankle replacement in people with hemophilia...

OBJECTIVE: TKA outcomes are worse for patients from poor neighborhoods, but whether education mitigates the effect of poverty is not known. We assessed the interaction between education and poverty on 2-year WOMAC pain and function. METHODS: Patient level variables from an institutional registry were linked to US Census Bureau data (census tract (CT) level). Statistical models including patient and CT level variables were constructed within multilevel frameworks...

INTRODUCTION: We have studied the early C-reactive protein (CRP) kinetics after proximal femoral fracture (PFF) surgery and defined a chart of CRP threshold values beyond which early postoperative complications are likely. MATERIALS AND METHODS: We have prospectively followed up a 42-patient cohort for surgical treatment by osteosynthesis or hip arthroplasty, and CRP was dosed at admission, on day 1, day 3, day 5 and then twice weekly for 30 days at the same time as a platelet count control of low molecular weight heparins...

PURPOSE: Cervical disc arthroplasty has been a popular alternative to traditional arthrodesis treatment for maintaining postoperative cervical spine mobility. However, certain adverse reactions to cervical disc arthroplasty have emerged during the last few decades. METHODS: Metallosis or metalloma is a rarely reported complication after spinal fusion or spinal arthroplasty surgery. We report on the first metallosis case occurring in a patient who received Bryan Disc implantation approximately 8 years earlier...

Subchondral cysts (or geodes) are common in osteoarthritis (OA), usually in association with other typical signs, i.e., joint space narrowing, subchondral bone sclerosis, and osteophytosis. However, large lesions without the typical signs of OA or lesions located outside the weight-bearing areas are unusual and may be confused for other conditions, in particular, those of tumoral origin. We report the findings in a 48-year-old man who had been complaining of left buttock pain for 3 years, getting worse over the last year, and an evolutive limited range of motion of the hip...

Symptomatic posttraumatic arthritis of the elbow in young patients is a disorder for which there is currently no satisfactory solution. In this case report we show the evolution of a comminuted fracture of the capitellum with trochlear extension (McKee typeIV) treated initially with open reduction and internal fixation that eventually required a resurfacing hemiarthroplasty of the capitellum and reconstruction of the lateral ligament complex. After this surgical procedure, the patient had evident improvement of pain and of elbow range of motion, keeping the possibility of performing other rescue techniques open if they were to be necessary in the future...

BACKGROUND: Knowledge of the minimal clinically important difference (MCID) for different shoulder outcome metrics and range of motion after total shoulder arthroplasty (TSA) can be useful to establish a minimum threshold of improvement that defines successful treatment. This study quantifies how MCID varies with different prosthesis types, patient age, gender, and length of follow-up after TSA. METHODS: A total of 466 anatomic TSA (aTSA) and reverse TSA (rTSA) with 2-year minimum follow-up were performed by 13 shoulder surgeons...

Pelvic discontinuity is a rare but serious problem in orthopedic surgery. Acetabular reconstruction in case of severe bone loss after failed total hip arthroplasty is technically difficult, especially in segmental loss type III (anterior or posterior) or pelvic discontinuity (type IV). Acetabular reinforcement devices are frequently used as load-sharing devices to allow allograft incorporation and in order to serve as support of acetabular implants. This study tries to show, by means of biomechanic work, the efficiency of reinforced plate in anterior column in a segmental pelvic loss, illustrated with a clinical case, which shows the socket stability of hip prosthesis...

BACKGROUND: The aim of this study is to compare the functional midterm outcome of stemless shoulder prostheses with standard anatomical stemmed shoulder prostheses and to show that the STEMLESS results are comparable to the STEMMED with respect to active maximum range of shoulder motion (ROM) and Constant score (CS). METHODS: Seventeen patients underwent total shoulder arthroplasty (TSA) in 25 shoulder joints. Stemless TSA was performed in 12 shoulder joints (group STEMLESS), third-generation stemmed TSA in 13 shoulder joints (group STEMMED)...

BACKGROUND: Total ankle arthroplasty (TAA) is commonly pursued for patients with painful arthritis. Outpatient TAA are increasingly common and have been shown to decrease costs compared to inpatient surgery. However, there are very few studies examining the safety of outpatient TAA. In this study, we retrospectively reviewed 65 consecutive patients who received outpatient TAA to identify complication rates. METHODS: The medical records of 65 consecutive outpatient TAA from October 2012 to May 2016 with a minimum 6-month follow-up were reviewed...
