Microfracture (MFX) is a common operation for articular cartilage lesions. Data for patients who underwent total knee arthroplasty (TKA) after previous MFX are limited. The purpose of this study was to determine the outcomes, complications, and factors that influence outcomes in patients with previous MFX compared with those without previous MFX. Between 2005 and 2014, twenty-one TKAs were performed at a single tertiary care academic institution in patients with prior history of MFX surgery. These patients were retrospectively reviewed and matched 2:1 to patients who did not undergo previous MFX (n=42)...

Recurrent patellar dislocation is observed in many patients treated nonoperatively following primary dislocation. Injury to the medial patellofemoral ligament (MPFL) is reported in the majority of patients following dislocation. There is an increased interest in repair or reconstruction of the MPFL for patients experiencing recurrent instability. The femoral attachment of the MPFL is critical in determining graft behavior following reconstruction. The femoral attachment can be determined by referencing local anatomy, fluoroscopic imaging or on the basis of desired graft-length changes...

Novel films on Ti-based orthopedic implants for localized antimicrobial delivery, which comprised dual-diameter TiO2 nanotubes with the inner layers of compact and Fluorine-free oxide tightly bonding to Ti, were formed by voltage-increased anodization with F- sedimentation procedure. The nanotubes were closely aligned and structured with upper 35 and 70 nm diametric tubes as nanocaps, respectively, and the underlying 140 nm diametric tubes as nanoreservoirs. Followed by loading ponericin G1 (a kind of antimicrobial peptide (AMP)) into the dual-diameter nanotubes with vacuum-assisted physisorption, the resultant films were investigated for loading efficiency and release kinetics of AMP, antibacterial activity against Staphylococcus aureus and osteoblastic compatibility, together with the AMP loaded single-diameter (140 nm) nanotube film...

In addition to tears of the rotator cuff, isolated impingement syndrome of the shoulder is the most common diagnosis in shoulder disorders. This is of high relevance in orthopedic sports medicine. In fact, impingement of the shoulder is not the diagnosis but rather a symptom of a functional or even a structural pathology. Detailed knowledge about the different types of impingement and the underlying causes is essential to provide adequate treatment. Primarily, impingement of the shoulder should be treated nonoperatively...

We describe a low-cost (instrument cost) technique for joint distraction using 2 Kirschner wires and a toothed lamina spreader in lieu of a Hintermann distractor. The described technique allows for temporary intra-articular distraction and visualization and preservation of the articular surface with extra-articular instrumentation. The technique can also allow for closed reduction and percutaneous treatment in cases of soft tissue compromise. Additionally, the technique uses common orthopedic surgical instruments, leading to a minimal learning curve for novice surgeons...

The practice of nuclear medicine in children is well established for imaging practically all physiologic systems but particularly in the fields of oncology, neurology, urology, and orthopedics. Pediatric nuclear medicine yields images of physiologic and molecular processes that can provide essential diagnostic information to the clinician. However, nuclear medicine involves the administration of radiopharmaceuticals that expose the patient to ionizing radiation and children are thought to be at a higher risk for adverse effects from radiation exposure than adults...

Combined spinal anesthesia and postoperative epidural analgesia is widely used in orthopedic surgery. Uncommon but serious neurologic complications of neuraxial anesthesia (NA) include direct trauma during needle or catheter insertion, central nervous system infections, and neurotoxicity of local anesthetics. Cauda equina syndrome (CES) is a rare complication after NA but can result in severe neurologic deterioration that may require surgical intervention. We present a case of a 69-year-old woman with postpolio syndrome who developed CES after combined spinal anesthesia and postoperative epidural analgesia...
