BACKGROUND: The National Institute for Health and Clinical Excellence (NICE) has issued guidelines on which thromboprophylaxis regimens are suitable following lower limb arthroplasty. Aspirin is not a recommended agent despite being accepted in orthopaedic guidelines elsewhere. We assessed the incidence of fatal pulmonary embolism (PE) and all-cause mortality following elective primary total knee replacement (TKR) with a standardised multi-modal prophylaxis regime in a large teaching district general hospital...

Osteoarthritis is a major cause of disability and there is no current pharmaceutical treatment which can prevent the disease or slow its progression. Dietary advice or supplementation is clearly an attractive option since it has low toxicity and ease of implementation on a population level. We have previously demonstrated that sulforaphane, a dietary isothiocyanate derived from its glucosinolate precursor which is found in broccoli, can prevent cartilage destruction in cells, in in vitro and in vivo models of osteoarthritis...

INTRODUCTION: The increase in the number of patients presenting with osteoarthritis in the past decade has led to a 32% increase in knee replacement surgeries designed to reduce restrictions on patient movement and improve their quality of life. Patient satisfaction is becoming an increasingly important indicator of quality of care. This study was designed to identify predictors of various service components in the treatment process and hospital key performance indicators significantly associated with patient satisfaction...

We present the case of a patient who suffered a comminuted supracondylar periprosthetic femur fracture. The patient was an 86-year-old lady who suffered a minor fall at home and presented at our hospital with a right comminuted distal femur fracture around a total knee arthroplasty. The patient was submitted to a cruciate-sacrificing total knee replacement 6 years before at the same institution. Despite severe metaphyseal fragmentation and short distal fragment, the prosthesis was stable; thus, open fracture reduction and stabilization with internal fixation were performed...

BACKGROUND: In a prospective cohort study, we wanted to detect thresholds distinguishing between patients with a satisfactory and an unsatisfactory outcome after total knee replacement (TKR) based on Patient-Reported Outcome Measures (PROMs), namely the Oxford Knee Score (OKS), using patient satisfaction and patient-perceived function as global transition items. METHODS: Seventy-three TKR patients completed the OKS questionnaire before surgery and were invited to complete the same questionnaire again 6 (4 to 9) months after surgery...

Background Total knee replacement is the only surgical option to treat painful degenerative osteoarthritis, restore knee function, improve quality of life, and enable patients to return to sports activity. With an aging population expecting an active life after retirement, patients' expectations of improvement after surgery are increasing as well. In view of the growing demand for higher performance, exercise and athletic activity, clinicians have been increasingly forced to question how much athletic activity a patient may resume after total knee replacement, and what types of athletic activity seem to be acceptable...

Total knee replacement for patients with osteoarthritis and valgus deformity remains challenging, with soft tissue balance often difficult to achieve. Most orthopedic surgeons use the medial parapatellar approach for total knee replacement. However, the lateral approach described in this case allows direct access to the pathology. The valgus deformity is corrected by using a modified lateral parapatellar arthrotomy with a staged and gradual release of the contracted lateral capsuloligamentous structures and the iliotibial tract...

BACKGROUND: Total knee replacement (TKR) is the commonest surgical procedure for patients with severe pain and impaired physical function following end stage knee osteoarthritis. The hip abductors are well renowned in stabilization of the trunk and hip during walking, maintaining the lower limb position, and transferring the forces from the lower limbs to the pelvis. OBJECTIVE: To assess the efficacy of hip abductor strengthening exercise on functional outcome using performance based outcome measures following total knee replacement...

Background and purpose - Psychosocial factors are important risk factors for poor outcomes in the first year after total knee replacement (TKR), however their impact on long-term outcomes is unclear. We aimed to identify preoperative psychosocial risk factors for poor outcomes at 1 year and 5 years after TKR. Patients and methods - 266 patients were recruited prior to TKR surgery. Knee pain and function were assessed preoperatively and at 1 and 5 years postoperative using the WOMAC Pain score, WOMAC Function score and American Knee Society Score (AKSS) Knee score...

AIMS: The objective of this study is to characterize, based on clinical, radiographic, health-related, quality-of-life-related, and demographic variables, the profile of a large, homogeneous, cohort of patients undergoing knee or hip arthroplasty, in a public hospital. Current regulatory guidelines for structure-modifying agent are not clear regarding hard clinical endpoint. The "need for surgery" has been suggested as a potential relevant outcome, but, until now, it is poorly defined...

BACKGROUND: Effective operating room ventilation is required to reduce the risk of surgical site infection. Vertical laminar airflow from above the surgical field provides a source of 'ultra-clean' air, carrying contaminants away from the operative site. An anaesthetic screening drape is often used to shield the operative site from the anaesthetic team, and this defies the principles of vertical laminar airflow. METHODS: A mock theatre set-up for a total knee replacement was constructed with and without the use of an anaesthetic screening drape...

INTRODUCTION: Total knee arthroplasty (TKA) is an operation with moderate to severe postoperative pain. The Fast-Track models employ local infiltration techniques with anaesthetics at high volumes (100-150ml). We proposed a genicular nerve block with low volume of local anaesthetic. The aim of our study is to evaluate the periarticular distribution of these blocks in a fresh cadaver model and to describe the technique in a preliminary group of patients submitted to TKA. MATERIALS AND METHODS: In the anatomical phase, 4 genicular nerves (superior medial, superior lateral, inferior medial and inferior lateral) were blocked with 4ml of local anaesthetic with iodinated contrast and methylene blue in each (16ml in total)...

Complications in the patellofemoral (PF) joint of patients with total knee replacements include patellar subluxation and dislocation, and remain a cause for revision. Kinematic measurements to assess these complications and evaluate implant designs require the accuracy of dynamic stereo-radiographic systems with 3D-2D registration techniques. While tibiofemoral kinematics are typically derived by tracking metallic implants, PF kinematic measurements are difficult as the patellar implant is radiotransparent and a representation of the resected patella bone requires either pre-surgical imaging and precise implant placement or post-surgical imaging...
