The temporomandibular joint (TMJ) is the most active, functioning joint of the body. Limitations of the mouth opening and deformity of the lower jaw can be caused by bony or fibrous ankylosis of the TMJ due to various reasons and mostly is due to fusion of the condyle to the base of the skull. Trauma to the TMJ is the most common etiology of ankylosis of TMJ. Clinical examination, radiographic ...

INTRODUCTION: Proper bone cut and soft tissue balancing are the most critical procedures in total knee arthroplasty (TKA). A gap balancing technique is commonly used in TKA to create an equal extension and flexion gap. However, obtaining a flexion gap sufficiently large for the extension gap in cruciate retaining (CR) TKA is sometimes difficult and the flexion gap in CR TKA tends to be smaller ...

Treatment of the posterior cruciate ligament (PCL) is a matter of continued controversy in total knee arthroplasty. By using so-called cruciate ligament-substituting implant designs, retention and resection of the PCL produce equivalent clinical results. However, it remains unclear whether primary resection of the PCL leads to relevant instabilities of the flexion gap. Especially when the incre...

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...
