Background. Multiple Sclerosis (MS) is a chronic autoimmune demyelinating disease. Muscle weakness, tremors, balance disorders, and gait instability are observed in MS patients. Also, respiratory muscles weakness can lead to decreased respiratory capacity, resulting in pneumonia and acute respiratory failure. Objectives. This study evaluates thoracic kyphosis angle (TKA) and respiratory functi...

Metallosis and corrosion have been associated with metal-on-metal modular total hip arthroplasty but are rarely described in the setting of primary or revision knee (TKA). In this series, we report on cases metallosis due to mechanically assisted crevice at junctions machined trunnion-bore tapers a TKA system metaphyseal sleeves. The unique design metal used sleeve-based TKA, along potential pa...

BACKGROUND The effect of patient education before total knee arthroplasty (TKA) is controversial. No consensus exists about the optimal content of educational interventions. In a previous study, we developed and validated an educational booklet on the peri-TKA management of knee osteoarthritis. PURPOSES Our primary purpose was to evaluate the impact of the educational booklet on knowledge amo...

Total knee arthroplasty (TKA) has a well-established track record for relieving pain associated with arthritis of the knee joint. The total rate of bilateral TKA has doubled over the past 2 decades, and the rate in women has tripled over that same time period. In patients with bilateral knee arthritis, a decision must be made whether to operate at 2 different settings (staged), a single setting...

INTRODUCTION Assessment of soft-tissue balance by the gap technique in Total Knee Arthroplasty (TKA) impacts femoral component rotation positioning. Proper femoral component rotation is a critical factor in TKA, both for adequate patellar tracking and in achieving a symmetrical flexion gap. Soft tissue balance assessment and gap measurements are performed at 90° flexion and with the patella eve...

Introduction: Evaluation of hospital readmissions after total knee arthroplasty (TKA) may provide an opportunity for improved patient safety and cost reduction. Despite the established effectiveness of TKA for treatment of arthritis, it is a very costly procedure. Thus, it is of great interest to find ways of reducing costs while ensuring that patient safety and outcomes are not compromised. Th...

Posterolateral rotatory instability is a relatively uncommon cause of unstable total knee arthroplasty (TKA). In most cases, surgical treatment requires revision TKA into a more constrained design or thicker polyethylene liner. We present a case of a patient with unstable TKA who remained unstable after increasing thickness of the polyethylene liner and undergoing more constrained TKA. After se...

Total knee arthroplasty (TKA) is associated with considerable postoperative pain. The relative analgesic efficacy and adverse effect profile of perioperative use of selective cyclooxygenase-2 (COX-2) inhibitors for patients undergoing TKA are unclear. This is a systematic review and meta-analysis of all randomized controlled trials evaluating perioperative administration of COX-2 inhibitors for...

INTRODUCTION Today elderly people live longer and also represent an increasing percentage of individuals with symptomatic end-stage arthritis of both knees. Many of them may benefit from total knee replacement (TKA). However the surgeon and patient are faced with the decision of whether to proceed with a staged bilateral TKA, done as two unilateral TKA procedures performed on different days, or...

Despite the evolution in implant design, surgical technique, rehabilitation and better medical training, a great number of patients are not satisfied with final result Total Knee Arthroplasty (TKA). The conventional TKA technique could high outliers limb alignment related to rate residual symptoms.
