Kinematic analysis of stair climbing in rotating platform cruciate-retaining and posterior-stabilized mobile-bearing total knee arthroplasties.
The aim of our study was to compare and contrast the effects of two types of mobile-bearing total knee arthroplasties (TKA), namely, the cruciate-retaining (CR) and posterior-stabilized (PS) TKAs, on clinical outcomes and in vivo kinematics during stair climbing. ⋯ IV.

Changes of posterior condylar offset results in midflexion instability in single-radius total knee arthroplasty.
There is no algorithm for the management of joint stability in midflexion up to now. Change in the joint line (JL) is considered to be the primary cause, although it only determines the extension gap. The purpose of this study was to determine the influence of the posterior condylar offsets (PCO), which defines the flexion gap, on midflexion instability. ⋯ Whereas the joint line can be displaced by up to 5 mm without measurable changes in joint stability, reconstruction of the posterior offset within a tight range of 2 mm is necessary to avoid midflexion instability.

USG-guided injection of corticosteroid for lateral epicondylitis does not improve clinical outcomes: a prospective randomised study.
Corticosteroid injection used to be the treatment of choice for lateral epicondylitis. Most injections are performed blindly. In the blinded technique, it could be difficult to determine the exact pathological localisation. The purpose of this single-blinded, randomised controlled clinical study was to compare the clinical therapeutic effects of blinded and USG-guided corticosteroid injection therapy in lateral epicondylitis. ⋯ There was no statistically significant difference compared to the blinded injection technique, and the mean score differences between the groups are of no clinical relevance.
