In this article, we present a new approach to double-bundle ACL reconstruction: a biological fixation of the tibial side by means of a double tunnel and a U-shape passage of an anterior tibialis allograft, fixed into a double tunnel on the femoral condyle with 2 interference bioabsorbable screws. The technique is designed to combine 2 known procedures for the regular knee surgeon: the mono-tunnel technique and the medial-portal approach.Read the article online: ORTHOSuperSite.com/view.asp?rID=84021 Interview Periprosthetic Joint InfectionIn this issue of ORTHOPEDICS, Dr Javad Parvizi discusses the diagnostic challenges of and treatment options for periprosthetic joint infection, as well as the importance of reducing its incidence.Read the article online: ORTHOSuperSite.com/view.asp?rID=84033 The Cutting Edge Single Percutaneous Injection of Stromal Cell-derived Factor-1 Induces Bone Repair in Mouse Closed Tibial Fracture ModelStromal cell-derived factor-1 is a dominant chemokine in bone marrow that is known to be involved in inflammatory diseases, including rheumatoid arthritis. Its role in bone repair has recently been demonstrated. The purpose of this study was to investigate the role of extraneous stromal cell-derived factor-1 in fracture healing. Read the article online: ORTHOSuperSite.com/view.asp?rID=84031 Pharmacology Update Use of Intranasal Medications in Pediatric PatientsA growing body of evidence supports the intranasal administration of atomized medications for a wide variety of pediatric indications. This article describes their use applicable to orthopedic specialists in the areas of pediatric pain management, as well as pre- and intraoperative sedation. As a quick, painless alternative to more invasive routes of administration, intranasal drug delivery has shown similar time to clinical effect compared to the intravenous route, while minimizing anxiety in both patients and their parents.Read the article online: ORTHOSuperSite.com/view.asp?rID=84035 Sports Medicine Update Physical Examination Findings in Young Athletes Correlate With History of Shoulder InstabilityThe goal of this study was to evaluate physical examination findings in a healthy cohort and determine potential correlations with a history of shoulder instability. A cross-sectional analysis was performed using the baseline data for an ongoing prospective cohort study to examine the risk factors for shoulder instability. A complete history of shoulder instability events was obtained, and a blinded physical examination was performed. Read the article online: ORTHOSuperSite.com/view.asp?rID=84032 Evidence-based Medicine Single-level Posterolateral Arthrodesis, With or Without Posterior Decompression, for the Treatment of Isthmic SpondylolisthesisIn this issue, we examine a study published in 1997 in the Journal of Bone and Joint Surgery, American Volume, that investigated whether the addition of decompression to arthrodesis, performed with or without instrumentation, for the treatment of low-grade isthmic spondylolisthesis in patients who do not have a serious neurological deficit would improve the result. Read the article online: ORTHOSuperSite.com/view.asp?rID=84022 Review Article COX-2 Inhibitors for the Prevention of Heterotopic Ossification After THA Nonsteroidal anti-inflammatory drugs (NSAIDs) may prevent heterotopic ossification after total hip arthroplasty (THA). Cyclooxygenase 2 (COX-2) inhibitors may minimize side effects. The goal of this review was to compare the effectiveness and side effects of the perioperative use of selective COX-2 inhibitors with those of conventional NSAIDs in patients undergoing THA.
