Although previous studies have evaluated the effect of obesity on the outcomes of total knee arthroplasty (TKA), most considered obesity as a binary variable. It is important to compare different weight categories and consider body mass index (BMI) as a continuous variable to understand the effects of obesity across the entire range of BMI. Therefore, the objective of this study is to analyze the effect of BMI on 30-day readmissions and complications after TKA, considering BMI as both a categorical and a continuous variable. ⋯ Obesity increased the risk of readmission and various complications after TKA, with the risk being dependent on the severity of obesity. Relationships between BMI and complications showed considerable variations with some outcomes like readmission and reoperation showing a U-shaped relationship. Based on our findings, a potential BMI goal in weight management for obese patients could be established around 29-30 kg/m2, in order to decrease the risk of most TKA postoperative complications.

The purpose of this study is to evaluate clinical and radiographic outcomes after gender-specific patellofemoral arthroplasty (PFA) either isolated or combined with unicompartmental knee arthroplasty (UKA). ⋯ Excellent clinical and radiographic outcomes were achieved after PFA with a gender-specific implant both as isolated replacement and when combined with medial UKA. Bicompartmental replacement with small implants can be considered in patients with bicompartmental osteoarthritis and intact anterior cruciate ligament.

Randomized Controlled Trial
Oral vs Intravenous vs Topical Tranexamic Acid in Primary Hip Arthroplasty: A Prospective, Randomized, Double-Blind, Controlled Study.
Tranexamic acid (TXA) has demonstrated efficacy in reducing blood loss, reduction in hemoglobin, and blood transfusion requirements in primary total hip arthroplasty (THA). The optimal mode of TXA administration for patients undergoing primary THA is unclear. The purpose of this randomized controlled trial is to determine whether oral administration of TXA was superior to intravenous or topical routes in these patients. ⋯ The blood-sparing efficacy of oral TXA is comparable to that of the intravenous and topical forms. Oral TXA is recommended because of its cost-benefit superiority and ease of administration.

Randomized Controlled Trial
Does a Program Based on Cognitive Behavioral Therapy Affect Kinesiophobia in Patients Following Total Knee Arthroplasty? A Randomized, Controlled Trial With a 6-Month Follow-Up.
To evaluate the effects of a cognitive behavioral therapy (CBT) program on kinesiophobia, knee function, pain and pain catastrophizing in patients following total knee arthroplasty (TKA). ⋯ The CBT program was superior to standard care in reducing kinesiophobia, pain catastrophizing, and knee pain and in enhancing knee function in patients who have a high level of kinesiophobia following TKA. The treatment effect was clinically significant and lasted for at least 6 months after the end of the intervention.

Medial stability of the knee is considered to be associated with good clinical results after total knee arthroplasty (TKA). This study aimed to compare intraoperative soft tissue balance between cruciate-retaining (CR) and posterior-stabilized (PS) TKA performed by a newly developed medial preserving gap technique, which aimed at preserving medial stability throughout the range of motion. ⋯ PS-TKA similarly achieved medial stability comparable to CR-TKA using the medial preserving gap technique.
