ABSTRACT
Objective To compare the postoperative functional result of total knee arthroplasty (TKA) with gender-specific prosthesis versus TKA with conventional prosthesis in a 5-year period. Methods Retrospective study with functional evaluation of 30 patients (15 patients from each group) using scores (Knee Injury and Osteoarthritis Outcome Score [KOOS], Western Ontario and McMaster Universities arthritis index [WOMAC], and The Knee Society Clinical Rating System [KSS]) and range of motion (ROM) as methods of assessment. Results The differences found between the score values and ROM were not statistically significant. Conclusion The gender-specific prosthesis presents functional results equal to those of conventional prosthesis after 5 years postoperatively.

ABSTRACT Objectives: To compare the efficacy and safety of aspirin and rivaroxaban in preventing venous thromboembolism (VTE) after total knee arthroplasty (TKA). Methods: Thirty-two patients with osteoarthritis of the knee and knee arthroplasty indication were selected. The operated patients were randomized into two groups (A and B). Group A received 300 mg of acetylsalicylic acid (aspirin) and Group B received 10 mg of rivaroxaban daily for 14 days. Follow-up was performed weekly for four weeks and evaluated the presence of signs and symptoms of DVT, the healing of the surgical wound, and possible local complications such as hematoma, and superficial or deep infection that required surgical approach. Results: It was verified that there were no differences between groups (rivaroxaban and aspirin) regarding gender, age, and (p > 0.05). After using the general linear model (GLM) test, it was found that there was a decrease in Hb and Ht levels, preoperatively and at one, three, seven, and 14 days (Hb: p = 1.334 × 10-30; Ht: p = 1.362 × 10-28). However, they did not differ as to the type of medication (Hb: p = 0.152; Ht: p = 0.661). There were no identifiable differences in local complications, systemic complications, deep vein thrombosis (DVT), readmission to hospital, reoperation, or death (p > 0.05) between groups (rivaroxaban and aspirin). Conclusions: Both aspirin and rivaroxaban can be considered useful among drugs available VTE the prevention after TKA.
RESUMO Objetivos: Comparar a eficácia e a segurança da aspirina e rivaroxabana na prevenção de tromboembolismo venoso (TEV) após a artroplastia total de joelho (ATJ). Métodos: Foram selecionados 32 pacientes com osteoartrite do joelho e indicação de artroplastia do joelho. Os pacientes operados foram randomizados em dois grupos (A e B). Os pacientes do grupo A receberam 300 mg de ácido acetilsalicílico (aspirina) e os do grupo B receberam 10 mg de rivaroxabana diários durante 14 dias. O acompanhamento foi feito semanalmente durante quatro semanas e avaliaram-se a presença de sinais e sintomas de TVP, a cicatrização da ferida cirúrgica e possíveis complicações locais, como hematomas e infecção superficial ou profunda que necessitasse de abordagem cirúrgica. Resultados: Foi verificado que não houve diferenças entre grupos (rivaroxabana e aspirina) quanto a gênero, idade e lateralidade (p > 0,05). Após a aplicação do teste General Linear Model (GLM), verificou-se uma queda dos níveis de Hb e Ht pré-operatórios e a um, três, sete e 14 dias (Hb: p = 1,334 × 10-30; Ht: p = 1,362 × 10-28). Entretanto, não se observaram diferenças quanto ao tipo de medicação (Hb: p = 0,152; Ht: p = 0,661). Não foram identificadas diferenças entre os grupos (rivaroxabana e aspirina) quanto a complicações locais, complicações sistêmicas, TVP, reinternação, reoperação e óbito (p > 0,05). Conclusões: Tanto a aspirina como a rivaroxabana podem ser considerados úteis dentro das medicações disponíveis para a prevenção de TEV após ATJ.

ABSTRACT
PURPOSE: To compare the outside-in transtibial lateral and medial approaches for posterior cruciate ligament (PCL) reconstruction regarding the guidewires and popliteal artery integrity. METHODS: Twenty-two human cadaveric knees were used. A PCL tibial aimer was arthroscopically placed within the PCL footprint through the anteromedial portal for the medial approach and through the anterolateral portal for the lateral approach. For the medial approach, the drill guide was introduced through the anteromedial tibial cortex and the guidewire was advanced with the reamer beyond the posterior tibial cortex. For the lateral approach, the drill guide was introduced through the anterolateral tibial cortex and the guidewire was advanced with the reamer beyond the posterior tibial cortex. After this, the knee was dissected. The depth distance (DD) was defined as the distance between the popliteal artery and the tibial posterior cortex projected at the tibial level at which the guidewire intersected or passed by the artery. The guidewire travel distance was calculated as the distance the guidewire had to advance beyond the tibial cortex to intersect the popliteal artery or pass by it. RESULTS: With the medial approach, the popliteal artery was intersected in all knees with a mean DD of 12.20 mm and a mean guidewire travel distance of 15.90 mm. With the lateral approach, the popliteal artery was not intersected in any knee; its mean medial distance from the artery was 4.8 mm at a DD of 10.05 mm. There was a significant difference in the popliteal artery intersection incidence and DD between both groups (P < .0001 and P = .0003, respectively). CONCLUSIONS: The transtibial lateral approach for PCL reconstruction was a safer method than the medial approach regarding popliteal artery injury by a guidewire. CLINICAL RELEVANCE: This study presents a slight modification of the most frequently used PCL reconstruction technique, intending to minimize guidewire injury to the popliteal artery.
