Quadrilateral space syndrome: The forgotten differential.

The quadrilateral space is bounded by the teres minor superiorly, the teres major inferiorly, the long head of the triceps medially and the shaft of the humerus laterally. The axillary nerve and posterior circumflex humeral artery pass through this space to enter the posterior compartment of the upper arm. Quadrilateral space syndrome (QSS) is caused by entrapment of the axillary nerve or its main branches and/or the posterior circumflex humeral artery in the quadrilateral space by internal or external compression.

Role of High Tibial Osteotomy in Cartilage Regeneration - Is Correction of Malalignment Mandatory for Success?

Malalignment of the knee can cause debilitating symptoms such as pain, resulting in a decline in function and mobility. Surgical options that exist to address this problem include realignment osteotomies and joint replacements. Realignment osteotomies are the more appropriate options in certain patient populations, especially with regard to age and level of activity.

Patient satisfaction after total knee arthroplasty: an Asian perspective.

Introduction: Total knee arthroplasty (TKA) is an effective method for alleviating pain and restoring knee function in patients with severe osteoarthritis. However, despite the improvements in surgical technique and postoperative care, it has been reported that up to 19% of patients are dissatisfied after their operations. The aim of this study was to evaluate patient satisfaction levels after TKA in an Asian cohort, as well as assess the correlation between patient satisfaction levels and the results of traditional physician-based scoring systems.
