BACKGROUND: Postoperative limb positioning has been reported to be an efficient and simple way to reduce blood loss and improve range of motion following total knee arthroplasty (TKA). This meta-analysis was designed to compare the effectiveness of two different limb positions in primary TKA. MATERIALS AND METHODS: A meta-analysis of the PubMed, CENTRAL, Web of Science, EMBASE and Google Search Engine electronic databases was performed. In this meta-analysis, two postoperative limb positions were considered: mild-flexion (flexion less than 60°) and high-flexion (flexion at 60° or more)...

BACKGROUND: Periprosthetic joint infection (PJI) following total hip arthroplasty (THA) can be treated with irrigation and debridement with head and polyethylene exchange (IDHPE) or 2-stage revision (2SR). Few studies have compared patient-reported outcome measures (PROMs) in patients managed with these treatments. METHODS: A retrospective review identified 137 patients who had an infected primary THA between 1986-2013. Control cohorts were matched according to age and Charlton Comorbidity Index (CCI)...

In recent years, with the higher median life expectancy, the number of hip and knee replacements has increased. Clinical examination and morphological studies are essential to evaluate patients with a painful arthroplasty. Nuclear medicine examinations also play an important role, their main usefulness being the exclusion of prosthesis complications. Nevertheless, conventional examinations, namely bone scan and white blood cell scintigraphy, can also identify complications, such as loosening and infection. This study describes the normal and pathologic patterns of a bone scan and exemplifies ten common situations that can cause pain in patients with hip or knee arthroplasty, other than loosening and infection, which can be disclosed on a bone scintigraphy...

Knee extensor mechanism rupture is a serious complication of total knee arthroplasty (TKA). Its prevalence ranges from 1 to 10% and it is commonly observed as a chronic multifactorial pathology with the patellar tendon as the most common site of rupture. Knee extensor mechanism reconstruction can be performed using allogenic or synthetic grafts. In the literature it is still not clear whether one of these techniques is superior to the other and the choice is usually tailored to the patient case by case. Allografts allow better restoration of the anatomical landmarks, whereas the mesh technique is more reproducible and the graft does not elongate over time...

Surgical site infection (SSI) is a disastrous complication after total knee arthroplasty (TKA) which can cause prosthesis loosening and may end up in septicaemia. The incidence of infection reported to be in the range of 0.3-12.4% for primary TKA. Significantly higher infection rate is found in the morbidly obese patients. The current study compared the immediate rate of post-total knee replacement wound infection in the obese versus non-obese population. The cross-sectional study was conducted at Aga Khan University Hospital (AKUH) and comprised patients undergoing TKA for primary knee osteoarthritis...

BACKGROUND: Biologic agents have contributed significantly to the management of patients with in rheumatoid arthritis (RA). A significant proportion of patients with RA still require arthroplasty procedures however. It is unclear whether these agents increase the risk of post operative infection after lower limb arthroplasty . The aim of this review is to review the contemporary literature about this topic along with the recommendations from specialist societies. METHOD: A literature search was performed for articles published over the last 10 years in the English language examining the association between anti-tumour necrosis factor inhibitors and the incidence of post operative infection in patients with RA undergoing hip and knee arthroplasty procedures...

: Antibiotic resistance of bacterial biofilms limits available treatment methods for implant-associated orthopaedic infections. This study evaluated the effects of applying cathodic voltage-controlled electrical stimulations (CVCES) of -1.5V and -1.8V (vs. Ag/AgCl) to coupons of commercially pure titanium (cpTi) incubated in cultures of methicillin-resistant Staphylococcus aureus (MRSA) and Acinetobacter baumannii (A. baumannii) as a method of preventing bacterial attachment. Stimulations were applied for 2, 4, and 8 hours and coupon-associated and planktonic colony-forming units (CFU) were enumerated following stimulation...

BACKGROUND: Periprosthetic shoulder infections (PSIs) are challenging to treat and often result in significant patient morbidity. Without a standardized treatment protocol, PSIs are often managed similarly to periprosthetic hip and knee infections. Because 2-stage revision is the gold standard for treating periprosthetic hip and knee infections, we performed a case series and literature review to determine its effectiveness in PSIs. METHODS: We identified 19 patients (14 men) from our institution who were treated with a 2-stage revision after presenting with a PSI...

BACKGROUND: Propionibacterium (P) acnes infection of the shoulder after arthroplasty is a common and serious complication. Current detection methods for P acnes involve anaerobic cultures that require prolonged incubation periods (typically 7-14 days). We have developed a polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) approach that sensitively and specifically identifies P acnes in tissue specimens within a 24-hour period. METHODS: Primers were designed to amplify a unique region of the 16S rRNA gene in P acnes that contained a unique HaeIII restriction enzyme site...

Prosthesis retention is not recommended for multidrug-resistant Acinetobacter prosthetic joint infection due to its high failure rate. Nevertheless, replacing the prosthesis implies high morbidity and prolonged hospitalization. Although tigecycline is not approved for the treatment of prosthetic joint infection due to multidrug resistant Acinetobacter baumannii, its appropriate use may preclude prosthesis exchange. Since the area under the curve divided by the minimum inhibitory concentration is the best pharmacodynamic predictor of its efficacy, we used tigecycline at high dose, in order to optimize its efficacy and achieve implant retention in 3 patients who refused prosthesis exchange...

PURPOSE: Recurrent spontaneous hemarthrosis is an infrequent but debilitating late complication of joint replacement, affecting up to 1.6% of patients with arthroplasty of the affected joint. Repeated episodes of bleeding result in an inflammatory cascade that further propagates bleeding events. Open and arthroscopic synovectomy are often performed when conservative treatments fail. Transarterial embolization is increasingly utilized as a less invasive option; however, its role is not widely established...
