Despite its limitations, citation analysis remains one of the best currently available tools for quantifying the impact of articles. Bibliometric studies list the "best-sellers" in a single location, and they have been published frequently in many fields during recent years. The purpose of the present study was to report the qualities and characteristics of citation classics in orthopaedic knee research. ⋯ This bibliometric study is likely to include a list of intellectual milestones in orthopaedic knee research. It is apparent that a high level of evidence is not mandatory for an article to gain a large number of citations. Bibliometric reports provide a reflection of the quality of cited research published in a specific field and should therefore provoke thinking within the scientific community.

Clinical TrialStability assessment of the ankle mortise in supination-external rotation-type ankle fractures: lack of additional diagnostic value of MRI.
This prospective diagnostic study assessed the utility of MRI (magnetic resonance imaging) findings for the deep aspect of the deltoid ligament in evaluating the stability of the ankle mortise in patients who have an SER (supination-external rotation)-type lateral malleolar fracture with no widening of the medial clear space. ⋯ On the basis of the study results, we do not recommend the use of MRI when choosing between operative and nonoperative treatment of an SER-type ankle fracture.

The presence of a negative sacral slope in patients with ankylosing spondylitis with severe thoracolumbar kyphosis.
Pelvic retroversion is one of the mechanisms for regulating sagittal balance in patients with a kyphotic deformity. This retroversion is limited by hip extension, which prevents the pelvis from becoming excessively retroverted, achieving a sacral slope of <0°. However, a negative sacral slope can be found in some patients with ankylosing spondylitis with thoracolumbar kyphosis. The purpose of this study was to analyze this finding. ⋯ Negative sacral slope does exist in Chinese Han patients with ankylosing spondylitis with thoracolumbar kyphosis. This appears to be caused by severe kyphosis, an initially small sacral slope, and pronounced tilting of the femoral shaft as a result of knee flexion, resulting in the pelvis becoming further retroverted.

Randomized Controlled TrialImproving residency training in arthroscopic knee surgery with use of a virtual-reality simulator. A randomized blinded study.
There is a paucity of articles in the surgical literature demonstrating transfer validity (transfer of training). The purpose of this study was to assess whether skills learned on the ArthroSim virtual-reality arthroscopic knee simulator transferred to greater skill levels in the operating room. ⋯ We believe that the results of our study will stimulate residency program directors to incorporate surgical simulation into the core curriculum of their residency programs.
