Introduction The total knee arthroplasty (TKA) has been shown to be a successful and cost-benefit procedure in terms of pain improvement in patient with symptomatic knee osteoarthritis. However, almost a 20% of the patients are not satisfied with the result of the surgery. Material and method We have carried out a transversal unicentric cases controls study with clinical cases of the own hospital, obtained by a clinical records revision. A total of 160 patients with a TKA with at least 1 year of follow-up were selected...

BACKGROUND AND OBJECTIVES: The purpose of this study is to analyze the indications, complications, survivorship and clinical/functional outcome of metaphyseal sleeves as a treatment option in revision total knee arthroplasty. MATERIAL AND METHOD: A systematic review was made following the PRISMA recommendations on the use of metaphyseal sleeves for revision total knee arthroplasty. We included prospective and retrospective studies published in the last 10 years looking at implant survivorship, clinical and functional outcome with a minimum follow-up of 2 years...

In a patient with severe unicompartmental knee osteoarthritis where conservative treatments have been exhausted, with painful symptoms located on the affected side and with a reducible axis, the unicompartmental knee prosthesis (UKP) is the first option for our work group. Within the study to confirm the diagnosis and plan the surgery, weight-bearing knee x-rays, Rosenberg x-rays, and teleradiographs of the lower extremities stand out. The objective of surgery is to replace the affected area, restoring the anatomy with an adequate balance of soft tissues...

BACKGROUND AND OBJECTIVE: Frailty scores have not been standardized for the preoperative assessment of patients undergoing total knee replacement (TKR). The aim of this study was to compare the efficacy of the American Society of Anesthesiology (ASA) score, the Charlson Comorbidity Index (ICC) and the Simple Frailty Score (SSF) in predicting complications, hospital stay, readmissions and mortality after elective KTR. MATERIALS AND METHODS: We retrospectively studied 448 patients who underwent KRT for osteoarthritis at our institution between 2016 and 2019...

BACKGROUND AND OBJECTIVES: The ideal timing of tranexamic acid administration in total knee arthroplasty with tourniquet remains unclear. Our primary objective was to prove if administering it before surgical incision, instead of before releasing the tourniquet, reduces postoperative bleeding. A second objective was to determine whether a second dose reduces post-operative bleeding. MATERIAL AND METHODS: A prospective, double-blind clinical trial was performed on 212 patients scheduled for total knee arthroplasty...

BACKGROUND AND OBJECTIVE: Knee arthroplasty is a major surgery with potential significant blood loss. Assess the efficacy and safety of topical administration of 3g of tranexamic acid (TXA) in terms of reducing blood loss in knee arthroplasty. MATERIAL AND METHOD: A randomized, phase III, double-blind, placebo-controlled clinical trial has been conducted. We included 150 patients in 2 parallel treatment groups (75 per arm). The solution was administered topically intra-articular after cementation and prior to capsular closure...

OBJECTIVE: To analyze the clinical and radiologic results, the survival and complications obtained in 70 year or older patients who underwent cementless total knee arthroplasty (TKA). MATERIAL AND METHOD: An observational study of patients operated between January 2014 and December 2016 was carried out according to the Natural Knee model (Zimmer®, USA). The main variables were the Oxford Knee Score, the visual analog scale, the presence of radiolucencies, complications, survival and reasons for revision...

INTRODUCTION: Patellar tendon rupture has a higher prevalence in older patients related to systemic diseases such as rheumatoid arthritis, lupus erythematosus and those with prolonged treatment with corticosteroids or antibiotic therapy. It is caused by trauma with the knee in flexion accompanied by a contraction of the quadriceps or eccentric force, the diagnosis can be omitted in up to 38% of cases. Treatment of non-recent tendon ruptures is more difficult with end-to-end techniques are complicated and difficult to perform 45 days after injury due to quadriceps retraction, fibrosis, adhesion formation, and muscle hypotrophy...

Total knee arthroplasty is one of the most frequently performed orthopaedic surgeries. However, up to 20% of patients develop persistent postoperative pain. Persistent postoperative pain may be an extension of acute postoperative pain, but can also occur after more than 3 months without symptoms. Risk factors associated with persistent postoperative pain after arthroplasty have now been characterised within the patient's perioperative context (preoperative, intraoperative and postoperative), and can be grouped under genetic, demographic, clinical, surgical, analgesic, inflammatory and psychological factors...

INTRODUCTION: There is a wide variety of functional tests and scales for the assessment of different aspects in the adaptation of amputees, but there is still no consensus on which are the most appropriate. OBJECTIVES: To describe the measures of correlation and association among three functional tests for lower-limb amputees and to define the most appropriate for this assessment. To assess general satisfaction in lower-limb prostheses users and its association with the functional tests...

BACKGROUND: Prosthetic joint infections are a cause of increasing morbidity and medical expenditure. OBJECTIVES: To determine the incidence and the clinical and the epidemiological characteristics of knee and hip prosthetic infections (PI) in patients undergoing elective surgery in five Catalonian hospitals. To determine the predictive factors of PI. METHODS: A total of 425 patients operated on between 8 January and 8 July 2001 were prospectively followed for a period of two years...
