Autologous bone grafting is an established method to overcome bone deficiencies in primary total knee arthroplasty (TKA). However, recently, metal augments have been used by many surgeons. Although autologous bone grafting is a common technique, few large studies have described its success in achieving bone union in primary TKA. The goal of this study was to evaluate primary TKA with autologous bone grafting for tibial defects. A total of 68 knees that had undergone arthroplasty with autologous bone grafting with more than 1 year of follow-up were evaluated...

Knee pain is commonly seen in orthopedic and rehabilitation outpatient clinical settings. Patients with knee osteoarthritis (OA) are often complicated with joint soreness, swelling, weakness, and pain. These complaints are often caused by the excessive amount of synovial fluid (SF) accumulated in the bursae around the knee joint. This study was aimed to evaluate the effectiveness of platelet rich plasma (PRP) in treating patients with minor to moderate knee osteoarthritis (OA) combined with supra-patellar bursitis using a proteomic approach and clinical evaluation tool...

BACKGROUND: Adjacent segment disease (ASD) is a common complication after lumbar decompression and fusion surgery. Traditional revision-surgery, including posterior lumbar decompression and posterolateral fusion (PLF) or interbody fusion (PLIF) is traumatic. The percutaneous endoscopic transforaminal procedure (PE-TF) has been widely used in patients with lumbar disc disease. However, there are no reports about using PE-TF procedure to treat ASD in the current literature. OBJECTIVE: To compare the clinical outcomes between PE-TF and PLF for single-level ASD after PLF or PLIF...

OBJECTIVES: Hip arthroscopy utilization has significantly increased in recent years. While it is a relatively safe procedure, it is not without risk. Life-threatening complications, albeit rare, can potentially occur and must be appropriately recognized and treated. We describe 2 cases in which patients' undergoing hip arthroscopy developed pulmonary edema and their respective courses of treatment. METHODS: Both patients were being treated for symptomatic femoroacetabular impingement (FAI), with labral tears, requiring operative management after a failed trial of conservative management...

Grant H Garcia, Ryan M Degen, Joseph N Liu, Cynthia A Kahlenberg, Daniel J Hurwit, Joshua S Dines
In response to recent concerns about the accuracy of suture passage during arthroscopic remplissage, this study was conducted to determine whether a previously described "safe zone" technique can improve the accuracy of suture passage. A recommended safe zone technique was used for arthroscopic remplissage on 6 cadaveric specimens. The safe zone was described as a region at least 1 cm lateral and no greater than 3 cm distal to the posterolateral acromion. Results were compared with a control group of 6 specimens for which the safe zone technique was not used...

REVIEW
Renee C Genova, Rachel L Box, James R Ficke
PURPOSE OF REVIEW: This review provides historical background on trauma care in the USA and summarizes contemporary trauma-related health policy issues. It is a primer for orthopedic surgeons who want to promote improvements in research, delivery, and cost reduction in trauma care. RECENT FINDINGS: As of 2010, funding for trauma research accounted for only 0.02% of all National Institutes of Health research funding. This is disproportionate to the societal burden of traumatic injury, which is the leading cause of death and disability among people aged 1 to 46 years in the USA...

Alterations have been made over the years to the standard reverse total shoulder arthroplasty (RTSA) prosthetic components in an effort to decrease adverse events; this has led to the advent of a short humeral stem prosthesis. To the authors' knowledge, there are no reports describing the complication of a traumatic periprosthetic Wright and Cofield classification type A fracture with use of a short metaphyseal humeral stem component for RTSA. The authors describe a 49-year-old woman with this pathology who was treated with open reduction and internal fixation using a proximal humerus locking plate, unicortical and bicortical screw fixation, and a cerclage wire construct without the need to violate the shoulder joint or revise components...

BACKGROUND We explored the application of 3-dimensional (3D) printing technology in treating giant cell tumors (GCT) of the proximal tibia. A tibia block was designed and produced through 3D printing technology. We expected that this 3D-printed block would fill the bone defect after en-bloc resection. Importantly, the block, combined with a standard knee joint prosthesis, provided attachments for collateral ligaments of the knee, which can maintain knee stability. MATERIAL AND METHODS A computed tomography (CT) scan was taken of both knee joints in 4 patients with GCT of the proximal tibia...

BACKGROUND: The primary treatment strategy for chronic atlantoaxial rotatory fixation (chro-AARF) is traction followed by bracing or application of a Halo device. However, to complete these conservative therapies, patient cooperation is mandatory. If conservative therapy fails, surgery is required for reduction and prevention of recurrence. It has been considered that surgery for AARF necessitates solid bony fusion. However, once bony fusion is achieved, loss of range of motion is problematic...

Rajesh Rangarajan, Rick F Papandrea, Akin Cil
For acute distal humeral fractures not amenable to open reduction and internal fixation, total elbow arthroplasty has become an established alternative. However, lifelong activity restrictions designed to prevent early mechanical failure make this a poor option for some patients. This has led to a renewed interest in distal humeral hemiarthroplasty. Using modern implants and techniques, distal humeral hemiarthroplasty has shown outcomes comparable to those of total elbow arthroplasty at short- to mid-term follow-up, with an overall higher but different complication rate...

OBJECTIVE: Postoperative infections, a serious complication of orthopedic surgery, occur 2-4 times more frequently in patients with rheumatoid arthritis (RA) without adjustment for medication. Some studies have demonstrated a similar risk of postoperative infection following orthopedic surgery regardless of whether patients underwent tumor necrosis factor-α (TNF-α) inhibitor therapy; however, other studies have reported a higher risk with TNF-α inhibitor use. However, few reports have focused on the correlation between TNF-α inhibitor use and postoperative late infection...
