BACKGROUND: A need exists for a functional anterior cruciate ligament (ACL) brace that dynamically supports the knee joint to match the angle-dependent forces of a native ACL, especially in the early postoperative period. PURPOSE/HYPOTHESIS: The purpose of this study was to quantify the posteriorly directed external forces applied to the anterior proximal tibia by both a static and a dynamic force ACL brace. The proximal strap forces applied by the static force brace were hypothesized to remain relatively constant regardless of knee flexion angle compared with those of the dynamic force brace...

A 24-year-old man with severe atopic dermatitis underwent anterior cruciate ligament (ACL) reconstruction of the right knee seven years earlier but developed a surgical site infection. The infection did not heal after removal of the metal implants, and a fistula eventually developed. This condition was left untreated for six years before he was referred to our hospital. Magnetic resonance imaging showed fluid in the tibial bone tunnel and extensive bone marrow edema surrounding the bone tunnel. Based on these findings, abscess formation within the tibial bone tunnel and osteomyelitis spreading to the proximal tibia were suspected...

We wished to evaluate whether inhibition of the systemic inflammatory response by a single pre-operative dose of methylprednisolone reduced markers of early endothelial damage after fast-track total knee arthroplasty. We randomly allocated 70 patients undergoing elective unilateral total knee arthroplasty (1:1) to receive either pre-operative intravenous methylprednisolone 125 mg (methylprednisolone group) or isotonic saline (control group). All procedures were performed under spinal anaesthesia without a tourniquet, using a standardised multimodal analgesic regime...

PURPOSE: Recurrent patellar dislocation is currently treated with anatomical reconstruction of the medial patellofemoral ligament (MPFL), and favourable postoperative outcomes have been reported. However, it is uncertain if healthy MPFL function is restored by anatomical reconstruction. The hypothesis in this study was that stabilization of the patella following MPFL reconstruction would be improved compared with that before surgery, but that function of the grafted tendon would differ from that of a healthy MPFL...

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is globally endemic and is a leading cause of surgical site infection (SSI). The purpose of this study was to evaluate the incidence of SSI in MRSA carriers undergoing elective hip or knee arthroplasty, who had confirmed eradication and to compare it with incidence of SSI in non-MRSA carriers. METHODS: This is a retrospective analysis of 6613 patients who underwent elective total hip arthroplasty (THA; n = 3347) and total knee arthroplasty (TKA; n = 3266) at our institution...

Previous studies suggest that metabolic disturbances might be involved in the development of osteoarthritis (OA). Associations have been found between the individual components of metabolic syndrome (MetS) and OA. MetS has been associated with increased oxidative stress (OxS). The study aimed to clarify the role of MetS components in OA and to evaluate the levels of OxS in OA patients and in age-matched controls. Fifty-five patients with end-stage OA (age 63 ± 7 years) prior to hip or knee joint replacement surgery and 55 age-, gender- and body mass index matched controls (61 ± 8 years) were enrolled in the study...

Staphylococcus aureus bloodstream infections (SABSI) are associated with high morbidity and mortality. The Toll-like receptor 2 (TLR2) and Toll-interacting protein (TOLLIP) are important in recognition and regulation of human innate immunity response to S. aureus. Single nucleotide polymorphisms (SNPs) in the TLR2 and TOLLIP encoding genes have been associated with disease, including BSI. The aim of this study was to examine potential associations between a selection of SNPs in the genes encoding TLR2 and TOLLIP, and predisposition, severity, and outcome of SABSI...

Limb salvage surgeries are performed to treat a variety of lower limb pathologies and traumatic injuries. Individuals who have undergone limb salvage surgeries may require an ankle foot orthosis (AFO) to compensate for limb impairments and restore walking ability. Understanding the effects of AFO design parameters on gait biomechanics is important to refine AFO prescription criteria. In this study sagittal plane kinematic and kinetic data, muscle activity and alignment preference were examined as individuals treated for traumatic lower extremity injuries (N=12) walked over level ground with Plantarflexed (PF), Neutral, and Dorsiflexed (DF) aligned AFOs...

BACKGROUND: Readmission rate has emerged as an important metric to measure quality, but varying definitions and timeframes are used. We aimed to evaluate the impact of different readmission definitions (postoperative vs postdischarge) and timeframes (30 vs 90-day) on capturing surgery-related readmissions after primary total joint arthroplasty. METHODS: Patients who underwent primary total hip or knee arthroplasty between January 1, 2013 and December 31, 2015 were included...

BACKGROUND: More than a million surgeries are performed annually in the United States for hip or knee arthroplasty or hip fracture stabilization. One-fifth of these patients have blood transfusions during their hospital stay. Increases in transfusion rates have caused concern about increased adverse events from unnecessary transfusions. METHODS: We systematically reviewed randomized trials examining the effect of restrictive vs liberal transfusion thresholds on patients having major orthopedic surgery...

BACKGROUND: Arthroscopic knee surgery frequently precedes total knee arthroplasty (TKA). There have been mixed data on the effect of prior arthroscopic surgery on results of TKA. The purpose of this study was to compare the 10-year Knee Society Score (KSS), survivorship, and complications of TKA in a cohort of patients who had a previous knee arthroscopy to a control cohort. METHODS: A retrospective review of 1315 TKAs who underwent a primary TKA between 2003 and 2004 was performed...

The knee kept forcibly in a flexed position is typical in cerebral palsy. Using a benchmark, we investigate intra-operatively if peak spastic hamstring force is measured in flexed knee positions. This tests the assumed shift of optimal length due to adaptation of spastic muscle and a decreasing force trend towards extension. Previously we measured spastic gracilis (GRA) and semitendinosus (ST) forces. Presently, we studied spastic semimembranosus (SM) and tested the following hypotheses: spastic SM forces are (1) high in flexed and (2) low in extended positions...

BACKGROUND: Venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis, is a serious complication after total joint arthroplasty (TJA). Risk assessment models are increasingly used to provide patient-specific risk stratification. A recently implemented protocol mandates calculation of a Caprini Score for all surgical patients at our institution. We investigated the accuracy of the Caprini Score in predicting VTE events following TJA. METHODS: A retrospective review of patients undergoing primary total hip (THA) and total knee arthroplasty (TKA) over a 1-year time period was performed...
