Total knee arthroplasty (TKA) designs are developed to optimize kinematics and improve patient satisfaction. The cruciate retaining (CR) and medially stabilized (MS) TKA designs have reported good mid-term follow-up outcomes. However, reasons for consistently high rates of patient dissatisfaction following a TKA remain poorly understood. To further investigate this, we compared the short-term functional outcomes and quality of life, using patient-reported outcome measures (PROMs) and range of motion (ROM), between a CR and MS TKA. ⋯ Patients who underwent the MS-TKA scored significantly better on the FJS and the quality of life subscale of the KOOS and KOOS-12 than those who underwent a CR-TKA. All other assessed PROMs and ROM were comparable between the 2 groups and demonstrated that both implants facilitated symptom relief and improved daily function at 1 year postoperatively. These findings suggest that at short-term follow-up, the MS device is more likely to allow a patient to "forget" that a joint has been replaced and restore their quality of life. Long-term assessment of MS-TKA design outcomes in larger cohorts is recommended.

There are significant variations in transfusion rates among institutions performing total joint arthroplasty. We previously demonstrated that implementation of an educational program to increase awareness of the American Association of Blood Banks' transfusion guidelines led to an immediate decrease in transfusion rates at our facilities. It remained unclear how this initiative would endure over time. We report the long-term success and sustainability of this quality program. ⋯ Application of this quality initiative was an effective means of identifying opportunities for quality improvement. The program was easily initiated, had significant early impact, and has been shown to be sustainable.

Knee arthroscopy (KA) is frequently performed to provide improved joint function and pain relief. However, outcomes following total knee arthroplasty (TKA) after prior KA are not fully understood. The purpose of this study is to determine the relationship between prior KA within 2 years of TKA on revision rates after TKA. ⋯ Level III therapeutic study.

The etiopathogenesis of developmental dysplasia of the hip (DDH) has not been clarified. This systematic review evaluated current literature concerning all known chromosomes, loci, genes, and their polymorphisms that have been associated or not with the prevalence and severity of DDH. ⋯ DDH is a complex disorder with environmental and genetic causes. However, no firm correlation between genotype and DDH phenotype currently exists. Systematic genome evaluation in studies with larger sample size, better methodological quality, and assessment of DDH patients is necessary to clarify the DDH heredity. The role of next-generation sequencing techniques is promising.

Tranexamic acid (TXA) administration to reduce postoperative blood loss and transfusion is a well-established practice for total knee arthroplasty (TKA) and total hip arthroplasty (THA). However, clinical concerns remain about the safety of TXA in patients with a history of a prothrombotic condition. We sought to determine the risk of complications between high-risk and low-risk TKA and THA patients receiving TXA. ⋯ TXA administration to high-risk TKA and THA patients is not associated with a statistically significant difference in adverse outcomes. We present incremental evidence in support of TXA administration for high-risk patients undergoing primary arthroplasties.
