A multidisciplinary approach has been shown to be effective for the treatment of intractable pain. However, few hospitals in Japan have established liaison clinics for such patients. In this study, we investigated the short-term results of a liaison clinic for patients with intractable chronic pain. ⋯ This liaison clinic for patients with intractable chronic pain was able to improve patient anxiety. Severe anxiety at the initial visit represented a risk factor for dropout from the clinic.

The incidence of periprosthetic femoral fractures (PFF) around a stable stem is increasing. The aim of this biomechanical study was to examine how three different methods of fixation, for Vancouver type B1 PFF, alter the stiffness and strain of a construct under various configurations, in order to gain a better insight into the optimal fixation method. ⋯ This study highlights that the inclusion of cables appears to damage the screw fixations and does not aid in construct stability. Furthermore, the degree of fracture reduction affects the whole construct stability and the bending behaviour of the fixation.

Traditional treatments for stiff knees, such as quadriceps snip and V-Y quadricepsplasty, require extensive soft tissue exposure and lead to recurrent poor arc of motion and a permanent extensor lag. In this study, we evaluated the effect of the quadriceps tendon pie-crusting release for treating limited knee flexion in total knee arthroplasty (TKA) and compared the outcomes of two surgical approaches. ⋯ The quadriceps tendon pie-crusting release technique was an effective procedure for improving knee flexion in cases of stiff knee. The midvastus approach maintained the integrity of the extensor mechanism and resulted in better outcomes than the parapatellar approach.

Diagnostic accuracy of ultrasonography in assessing meniscal injury: meta-analysis of prospective studies.
The accuracy of ultrasonography for diagnosing meniscal injury remains controversial. The aim of the present meta-analysis was to establish the role of ultrasonography in the diagnosis of meniscal injury by analyzing the data from prospectively designed studies. ⋯ Our results suggest that the diagnostic accuracy of ultrasonography for diagnosing meniscal injury is acceptable, with a high specificity but moderate sensitivity.
