Knee osteoarthritis (OA) is a highly prevalent disease and treatment options for early stages of OA are needed. Intraosseous injections of bone substitute and biologic materials have been proposed to expand the therapeutic arsenal by potentially halting OA progression and delaying the need for knee arthroplasty in patients with early/moderate-stage disease. Therefore, the goal of this study was assessed the efficacy and safety of subchondral intraosseous injection for the treatment of knee OA. ⋯ However, the current studies investigating these treatments exhibited high degree of heterogeneity in both measurement of outcomes and delivery of treatment, with a high risk of bias. This procedure should not be utilized in advanced knee OA. In light of the limitations of the current literature, advising in favor or against this therapy for early to moderate knee OA is challenging.

Compared with nonelective total knee arthroplasties (TKAs), elective procedures have more time for preoperative planning, which allows for potentially improved patient optimization, risk factor modification, and patient education. The purpose of this study was to (1) determine nationwide trends in operative times and (2) evaluate associations between surgery type, elective or nonelective, with respect to (a) operative times, (b) length of stay (LOS), (c) discharge dispositions, (d) 30-day postoperative complications, (e) reoperations, and (f) readmissions. The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for all primary TKAs performed between 2011 and 2016. ⋯ These associations remained significant with multivariate logistic regression. This study demonstrated that preoperative planning can help shorten operative times and LOS as well as reduce complication and reoperation rates. Alongside the direct advantages identified in this study, potential greater effects include superior patient outcomes and reduced health care costs.

The incidence of meniscal tear was reported to increase with the delay of anterior cruciate ligament reconstruction (ACLR). The tear may occur concurrently with the ACL injury or after the ACL injury. Few studies had focused on the patients whose meniscus is intact during ACL injury. ⋯ For patients without concurrent meniscal injuries with the ACL tear, the incidence of MMT significantly increased if ACLR was performed more than 12 months after injury. The medial meniscus was more prone to injury than the lateral meniscus in chronic ACL-deficient knee. ACLR should be performed earlier to reduce the risk of meniscal tears for patients without initially concurrent meniscal tear.
