Results of a fast-track knee arthroplasty according to the experience of a multidisciplinary team.

Introduction: Fast-Track is a multidisciplinary system that has changed the perception of total knee arthroplasty surgery. It's based on the education of the patient, an increased autonomy, adequate pain control and early mobilization. In the bibliography, there are no articles that refer to the evolution of the protocol once established, and most of them are comparatives with the previously existing conventional system.

Tibial tubercle osteotomy in septic revision total knee arthroplasty.

Purpose: The incidence of revision knee arthroplasty for infection is increasing and the required surgical approach for the revision is a challenge for surgeons. Extensile approaches are frequently used when it is impossible to evert the extensor mechanism. The aim of this paper is to report our experience with tibial tubercle osteotomy (TTO) and the functional results in patients who underwent a two-stage revision due to prosthesis infection.

New modified Achilles tendon allograft for treatment of chronic patellar tendon ruptures following total knee arthroplasty.

Introduction: Patellar tendon rupture is an infrequent but debilitating lesion. Several surgical repairs have been suggested for patellar tendon rupture. Our aim is to propose a modified technique from the classic Achilles allograft procedure.

Translation and validation of 'The Knee Society Clinical Rating System' into Spanish.

Purpose: The Knee Society Clinical Rating System (KSS) is a questionnaire evaluating knee function itself and the patient's ability to walk and climb stairs. The aim of our study is to present the validated translation of KSS into Spanish.

Methods: The validated method of translation-retrotranslation was used to translate KSS into Spanish.

Better outcomes in severe and morbid obese patients (BMI > 35 kg/m2) in primary Endo-Model rotating-hinge total knee arthroplasty.

The Endo-Model rotating-hinge prosthesis is preferably indicated as a primary implant in patients with advanced axial deviation of the lower limbs or unstable knees with severe bone defects. Outcomes were studied in 111 knees, operated in a three-year period; the mean followup was 28 months. Joint balance enhancement and limbs mechanical axis correction were achieved after surgery.

Relationship between the degree of osteolysis and cultures obtained by sonication of the prostheses in patients with aseptic loosening of a hip or knee arthroplasty.

Introduction: The pathogenesis of prosthesis loosening is not well understood. The aim of our study was to sonicate components of joint prostheses removed due to aseptic loosening, culture the sonicate fluid, and to correlate these results with the degree of radiological osteolysis.

Methods: From January 2008 to June 2009 all consecutive patients who underwent a revision of hip or knee prosthesis due to aseptic loosening were included in the study.

Total knee replacement and health-related quality of life: factors influencing long-term outcomes.

Objective: To evaluate health-related quality of life (HRQOL) in patients with osteoarthritis undergoing total knee replacement (TKR); identify the influence of sociodemographic, clinical, intraoperative, and postoperative variables on HRQOL; and determine patient perceptions at 7 years.

Methods: We conducted a prospective study with 7 years of followup. HRQOL measures (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC] and Short Form 36 [SF-36]); sociodemographic, clinical, intraoperative, inpatient, and postoperative data; patient perceptions of TKR outcomes; and physical activity at 7 years were determined.

Prevalence of knee osteoarthritis and analysis of pain, rigidity, and functional incapacity.

Knee osteoarthritis is one of the most prevalent health problems in our society. It accounts for 10% of all primary care visits in general medicine and 30% of outpatient appointments. The objectives of this cross-sectional descriptive study of 100 patients suffering from gonarthritis were to assess pain, functional capacity, and joint damage in patients diagnosed with knee osteoarthritis, as well as the possible repercussions for subsequent surgical treatment.

Hoffa's fat pad resection in total knee arthroplasty.

The authors have studied the consequences of resection of Hoffa's fat pad during total knee arthroplasty (TKA). Sixty eight patients undergoing primary TKA were randomised to have Hoffa's fat pad either resected or preserved. Biopsy specimens of Hoffa's fat pad were taken for pathological study in all patients.
