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.

ReviewRisk factors for cartilage damage and osteoarthritis of the elbow joint: case-control study and systematic literature review.
This case-control study compares patients with healthy elbows to a group of symptomatic patients with cartilage damage/osteoarthritis. ⋯ Cartilage damage/radiographic osteoarthritis of the elbow joint are rare with respect to the overall prevalence of osteoarthritis. In the large number of patients with cartilage damage/radiographic osteoarthritis of the elbow joint, occupational or athletic stress factors and injuries sustained, in addition to other causes (rheumatism, gout), can prove as possible causes of these as secondary to symptomatic forms of osteoarthritis.

Fracture reduction by postoperative mobilisation for the treatment of hyperextension injuries of the thoracolumbar spine in patients with ankylosing spinal disorders.
The aim of this study was to evaluate results of surgical stabilisation of hyperextension injuries of the thoracolumbar spine in patients with ankylosing spinal disorders using two different treatment strategies: the conventional open rigid posterior instrumentation and percutaneous less rigid posterior instrumentation. Surgical and non-surgical complications, the postoperative radiological course, and clinical outcome at final follow-up were comparatively assessed. Moreover, we sought to discuss important biomechanical and surgical aspects specific to posterior instrumentation of the ankylosed thoracolumbar spine as well as to elaborate on the advantages and limitations of the proposed new treatment strategy involving percutaneous less rigid stabilisation and fracture reduction by postoperative mobilisation. ⋯ This study indicates that the proposed treatment concept involving percutaneous less rigid posterior instrumentation and fracture reduction by postoperative mobilisation is feasible, seems to facilitate adequate reduction and restoration of pre-injury sagittal alignment, and might have the potential to reduce the rate of complications in the management of hyperextension injuries of the ankylosed thoracolumbar spine.
