Is It Appropriate to Treat Sarcoma Metastases With Intramedullary Nailing?
Patients with primary bone and soft tissue sarcoma are at risk for skeletal metastases. Although uncommon, these metastases can result in impending or pathologic fractures. Intramedullary nailing traditionally has been an accepted form of palliative treatment for patients with metastatic carcinoma, but we could find no studies that report specifically on intramedullary nailing of metastatic sarcoma lesions. ⋯ Level IV, therapeutic study.

Comparative StudyPain Control and Functional Milestones in Total Knee Arthroplasty: Liposomal Bupivacaine versus Femoral Nerve Block.
Although pain management after total knee arthroplasty (TKA) affects rehabilitation, length of stay, and functional outcomes, pain management for patients undergoing TKA has yet to be standardized. Femoral nerve blocks (FNBs) are commonly used as an adjunct; however, these can result in transient quadriceps weakness and have been associated with in-hospital falls. Periarticular infiltration of liposomal bupivacaine has been recently introduced as a long-acting analgesic that can be administered without affecting motor function. ⋯ Level III, therapeutic study.

Do Patients Taking Warfarin Experience Delays to Theatre, Longer Hospital Stay, and Poorer Survival After Hip Fracture?
Patients sustaining a fractured neck of the femur are typically of advanced age with multiple comorbidities. As a consequence, the proportion of these patients receiving warfarin therapy is approximately 10%. There are currently few studies investigating outcomes in this subset of patients. ⋯ Level III, therapeutic study.

Can Preoperative Patient-reported Outcome Measures Be Used to Predict Meaningful Improvement in Function After TKA?
Despite the overall effectiveness of total knee arthroplasty (TKA), a subset of patients do not experience expected improvements in pain, physical function, and quality of life as documented by patient-reported outcome measures (PROMs), which assess a patient's physical and emotional health and pain. It is therefore important to develop preoperative tools capable of identifying patients unlikely to improve by a clinically important margin after surgery. ⋯ Level III, prognostic study.

Do Stemmed Tibial Components in Total Knee Arthroplasty Improve Outcomes in Patients With Obesity?
Recent clinical studies have reported that patients with higher body mass index (BMI) are more likely to experience premature failure of total knee arthroplasty (TKA), lower knee scores, and perhaps more pain in the prosthetic joint. However, it is not known whether certain implant design features such as tibial stems might be associated with differences in the frequency of tibial pain in patients with higher BMIs. ⋯ Level I, therapeutic study.
