[Total knee replacement in patients under 60 years with high functional demand: functional outcomes and return to sports after an average 2-year follow-up].

Introduction: a common concern in presurgical medical appointment of total knee replacement medical appointment is return to exercise. The purpose of this study was to analyze functional results and return to sport in patients under 60 years of age after this surgery.

Material And Methods: we retrospectively analyzed 41 total knee replacements in 36 athletic patients (average age: 53 years [46-60]).

[Intraosseous vancomycin in total knee arthroplasty].

Introduction: intravenous antibiotic prophylaxis has significantly reduced the incidence of periprosthetic joint infection (PJI) in knee surgeries. However, for patients colonized with methicillin-resistant Staphylococcus aureus (MRSA) or those at risk of colonization, prophylaxis should include vancomycin. Intraosseous (IO) administration of vancomycin could enhance its effectiveness in total knee arthroplasty (TKA).

[Partial exchange of components in chronic hip infection].

Introduction: one- or two-stage total revision is considered the gold standard for the treatment of hip arthroplasty with chronic infection. However, during the removal of a fixed prosthetic component, the host bone may be damaged, making definitive prosthetic reimplantation difficult.

Objective: we present a series of patients treated for chronic periprosthetic hip infection with preservation of one fixed component.

Early appearance of radiolucent lines around total knee arthroplasty in rheumatoid arthritis patients. How does it impact the aseptic failure rate and functional outcomes at 13 years of follow-up?

Introduction: Aseptic total knee arthroplasty (TKA) failure has been associated with radiolucent lines. This study aimed to determine the impact of the early appearance of radiolucent lines (linear images of 1, 2, or > 2mm at the cement-bone interface) around the TKA on prosthetic survival and functional outcomes in rheumatoid arthritis (RA) patients during a 2-20 years follow-up.

Methods: We retrospectively analyzed a consecutive series of RA patients treated with TKA between 2000 and 2011.

Total Knee Replacement in Alkaptonuric Ochronosis.

Background And Objective: Alkaptonuria is a rare disease characterized by the accumulation of homogentisic acid (HGA). Over time, these patients may develop disabling ochronotic arthropathy. We present 2 cases of patients with end-stage arthropathy treated with total knee arthroplasty (TKA).

Arthroplasty as a treatment for acute and quiescent septic arthritis in native hips.

Introduction: The most feared complication in hip arthroplasty after septic arthritis is septic failure. It is considered that the two-stage treatment is the accepted treatment for acute septic hip arthritis. The objective in this work is to establish a therapeutic guideline for septic arthritis in native hips, proposing a two-stage treatment for acute, and a one-stage treatment for quiescent.
