Comparative Study
Evaluation of patellofemoral joint in ADVANCE Medial-pivot total knee arthroplasty.
ADVANCE Medial Pivot (MP) (Wright Medical) total knee arthroplasty (TKA) was established to replicate normal tibio-femoral knee joint kinematics, however, its influence on the patello-femoral (PF) joint is unclear. The purpose in this study was to assess the PF joint conditions in Advance MP TKA, via radiography and three-dimensional image-matching software. ⋯ ADVANCE MP TKA changed patello-femoral joint kinematics, compared to that found before surgery. The kinematic features were mainly due to the design concepts for tibio-femoral joint motion, indicating the difficulty to reproduce normal patello-femoral joint kinematics after TKA.

Multicenter Study
Subclinical bilateral involvement of the hip in patients with slipped capital femoral epiphysis: a multicentre study.
This study was conducted to assess the posterior inclination of the contralateral femoral epiphysis in patients with unilateral slipped capital femoral epiphysis (SCFE). ⋯ These findings suggested the possibility of bilateral hip involvement in SCFE patients. Hips with greater degrees of PSA (> 19°) are likely to become symptomatic.

To determine the effectiveness of bilateral decompression via a unilateral approach using unilateral pedicle screw fixation for two-level lumbar stenosis with instability. ⋯ Bilateral decompression via a unilateral approach using unilateral pedicle screw fixation for two-level lumbar stenosis with instability, which can maintain the lumbar lordosis and the disc space height, is an effective and less invasive method than with bilateral constructs.

Evaluation of management of the displaced intra-articular calcaneal fractures (DIACF) Sanders types II and III by using minimally invasive sinus tarsi approach and fixation by screws only technique. ⋯ The limited open sinus tarsi approach can be used successfully to treat displaced Sanders type II and III fractures. It allows for adequate visualization and reduction. Fixation by screws only is also sufficient. It also clearly avoids the major wound complication problems.

Internal fixation versus joint replacement for treating intracapsular hip fractures is still a major debate. The Targon FN fixation concept is innovative; two small case series are promising. We present the first larger series. ⋯ Our study confirms low general complication rates. However, implant perforation seems to be underestimated. Optimised reduction technique may help to reduce this complication.
