INTRODUCTION Assessment of soft-tissue balance by the gap technique in Total Knee Arthroplasty (TKA) impacts femoral component rotation positioning. Proper femoral component rotation is a critical factor in TKA, both for adequate patellar tracking and in achieving a symmetrical flexion gap. Soft tissue balance assessment and gap measurements are performed at 90° flexion and with the patella eve...

Accurate soft tissue balancing during total knee arthroplasty has a direct effect on patellofemoral tracking and knee range of motion. Numerous instruments and methods are available to balance knee prostheses. The eLIBRA Dynamic Knee Balancing System (Synvasive Technology, Inc, Reno, Nevada) is an electronic device that establishes femoral component rotation using ligamentous tone. The eLIBRA i...

PURPOSE To compare the measured resection technique and the gap balancing technique for correction of the femoral rotational alignment. METHODS 57 women and 6 men (mean age, 70 years) with end-stage osteoarthritis and <15º malalignment and <10º flexion contracture of the knee underwent primary total knee arthroplasty through the medial approach using the measured resection technique (n=34) or...

UNLABELLED Revision total knee arthroplasty presents a unique set of problems when attempting to balance flexion and extension gaps. Loss of soft tissue support and established deformity can make balancing difficult. One needs to balance the flexion and extension gap heights as well as medial and lateral symmetry, which may not always be attainable. We used a set of stepwise techniques to reest...

Ankylosis may be defined as the fusion of joint surfaces. Temporomandibular joint (TMJ) ankylosis is a condition that may cause chewing, digestion, speech, esthetic and psychological disorders. It is a devastating disorder resulting in inability to open the mouth. As a result of this, General anaesthesia, is very difficult to administer because laryngeal inlet is not directly visualized. Even t...

Preparing equal and rectangular extension and flexion joint gaps is the most important goal in TKA bec...

Twenty-six patients (12 males and 14 females) between two days and 41 years old with temporomandibular joint ankylosis were retrospectively reviewed. Thirty-three joints were involved; 19 unilateral and six bilateral. The aetiologies were trauma, 69.2%; infection, 15.4%; unknown, 11.5% and congenital, 3.9. The majority, 31 were intracapsular while the remaining two joints were extracapsular 51....

a procedure characterised by simple excision of the trapezium (Gervis 1949). This procedure does not restore the trapezio-metacarpal joint, but rather creates a gap between the articular surfaces of the metacarpal and the scaphoid bones. Recently Swanson described a new technique, in which the trapezium was replaced by a silicone implant. Reports of the early results ofhis method and some techn...

Introduction Modern designs are now contributing to a remarkable renewed interest in total ankle arthroplasty (TAA), but TAA is still not as successful as total hip and total knee arthroplasty [1]. Among the remaining issues there is the design of the prosthesis components, which are often claimed to be 'anatomical' or compatible with the bony and ligament structures. However, very little is re...

  Background:    Previous studies suggest total hip arthroplasty may have some benefits compared to hemi-arthroplasty for displaced intracapsular femoral neck fractures in patients more than 60 years of age. The primary research question of our study was whether in-hospital adverse events, post-operative length of stay (LOS) and mortality in patients 60 year of age or older differed between tot...
