Depressed patients feel more pain in the short term after total knee arthroplasty.

Purpose: The hypothesis of this study was that depressive patients feel more pain in the immediate TKA postoperative period in comparison with non-depressed patients.

Methods: The diagnosis of depression was made with the Geriatric Depression Scale Short Form. The Visual Analogic Score (VAS) was registered each 8 h during the first 3 days.

Local infiltration analgesia adds no clinical benefit in pain control to peripheral nerve blocks after total knee arthroplasty.

Purpose: To evaluate the effect of the local infiltration of analgesics for pain after total knee arthroplasty in patients treated with femoral and sciatic peripheral nerve blocks. The secondary objective was to detect differences in analgesic consumption as well as blood loss after local infiltration of analgesics.

Methods: Prospective randomized double-blinded study in patients who underwent a TKA for knee osteoarthritis under spinal anesthesia and treated with femoral and sciatic nerve blocks.

A new score assessing the surgical wound of a TKA and its relation with pain, infection and functional outcome.

Intra-osseous pin sites used in Computer Navigated knee Arthroplasty are known to cause complications including infection, neurovascular The aim of this study was to describe a new score to evaluate the clinical aspect of the TKA surgical wound and to correlate it with postoperative pain, infection and functional outcome at 1 year of follow-up. This score, ranging from 0 to 10, assessed 5 parameters; swelling, haematoma, erythema, blood drainage and blisters. One hundred fifty-nine consecutive TKA were prospectively evaluated.

No differences in functional results and quality of life after single-radius or multiradius TKA.

Purpose: The main objective of this study was to compare the functional results and the impact on quality of life after a single-radius or a multiradius TKA implantation. The secondary objectives were to compare range of motion, satisfaction and the ability to perform daily life activities with both types of implant. It was hypothesized that the single-radius TKA would lead to better functional results and better quality of life than the multiradius TKA.

Patient-reported allergies cause inferior outcomes after total knee arthroplasty.

Purpose: The main objective of this study was to analyse the outcomes after total knee arthroplasty (TKA) of a group of patients with at least one self-reported allergy and a group of patients without reported allergies. We hypothesized there is a significant negative influence on clinical outcome scores after TKA in patients with self-reported allergies.

Methods: Four-hundred and seventy-five patients who had undergone TKA were analysed preoperatively and 1 year after surgery.

Sealing of the intramedullar femoral canal in a TKA does not reduce postoperative blood loss: a randomized prospective study.

Background: Sealing of the femoral canal, usually with autologous bone, is a surgical procedure that is often performed during TKA surgery to decrease blood loss in the postoperative period. However, evidence as to the effectiveness of this surgical procedure is not conclusive. The objective of this study was to assess the effectiveness of this surgical action in reducing postoperative blood loss and the blood transfusion rate.

The use of erythromycin and colistin-loaded cement in total knee arthroplasty does not reduce the incidence of infection: a prospective randomized study in 3000 knees.

Background: The use of antibiotic-loaded cement is believed to prevent infection in primary total knee arthroplasty, but there is a lack of randomized studies to support this concept. The aim of this study was to evaluate the use of an antibiotic-loaded cement to reduce the infection rate in primary total knee arthroplasty.

Methods: This is a prospective randomized study with 2948 cemented total knee arthroplasties, in which bone cement without antibiotic was used in 1465 knees (the control group) and a bone cement loaded with erythromycin and colistin was used in 1483 knees (the study group).

Correlation study between KSS, WOMAC and SF-36 scores in patients undergoing total knee arthroplasty in a Spanish speaking population.

The aim of this study was to determine whether it is necessary to use the KSS, WOMAC and SF-36 scales in a Spanish speaking population. These 3 questionnaires were administered to 1000 consecutive patients in the TKA preoperative period. Pearson's correlation coefficient and coefficient of determination were obtained.

Extension malunion of the femoral component after retrograde nailing: no sequelae at 6 years.

Objectives: Supracondylar femoral fracture is a complex complication after total knee arthroplasty (TKA). One potential complication of retrograde locked nailing is malunion in extension of the femoral prosthetic component--produced by an overly posterior nail entry point in the intercondylar notch. The aim of this study was to determine the repercussion of this deformity on the midterm radiological and functional outcomes of TKA.

[Evaluation of the impact of the introduction of a functional knee arthroplasty unit].

Objectives: To evaluate the impact of a functional knee arthroplasty unit in Hospital de l'Esperança (Barcelona) on resource consumption, quality indicators and the direct costs of the healthcare process.

Method: We performed a retrospective study based on two cross-sections: the first in 317 patients who underwent surgery in 2004 before the implementation of the functional knee arthroplasty unit and the second in 624 patients who underwent surgery in 2005. Data related to the process, complications and costs were collected.

Knee Arthroplasty in Klippel-Trenaunay syndrome: a case presentation with 5 years follow-up.

Klippel-Trenaunay syndrome (KTS) is a triad of cutaneous hemangiomas, varicose veins, and localized hypertrophy of soft tissue and bone. Orthopedic surgical intervention may be required for the management of localized limb-length discrepancy or joint arthropathy, especially in the lower limb. We describe the management of a 33-year-old patient with a diagnosis of KTS and severe knee arthropathy.
