Use of an electronic system for soft tissue balancing in primary total knee arthroplasty.
نویسندگان
چکیده
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 is an articulating spacer that emulates implant trials before anteroposterior femoral cuts are made to obtain a dynamic gap symmetry.

Electronic measurement of soft-tissue balancing reduces lateral releases in total knee arthroplasty.
Soft tissue balancing during total knee arthroplasty (TKA) has a direct affect on patello-femoral tracking and knee range of motion, which are necessary for a well functioning TKA postoperatively. We report on the use of an electronic pressure sensing instrument for soft tissue balancing of the knee before completion of all intraoperative bone cuts, as a way to improve patellar tracking. ...
متن کاملSoft-tissue balancing during total knee arthroplasty in the varus knee.
Soft-tissue balancing during total knee arthroplasty is an important step in optimizing the mechanical balance of the knee joint. Soft-tissue contractures that result from varus coronal plane deformity can pose a difficult problem, and the surgeon should have a standard procedure for managing such situations in the operating room. Balance may be assessed intraoperatively with the use of spacer ...
متن کاملSoft-tissue balancing in primary total knee arthroplasty.
The surgical goal of primary total knee arthroplasty (TKA) is to provide a well-balanced soft-tissue envelope surrounding a well-aligned, well-fixed implant. Some knee surgeons have emphasized that a good outcome in primary TKA is more dependent on soft-tissue management than bone management. Thus, it is imperative that the surgeon is familiar with knee soft-tissue balancing techniques to addre...
متن کاملComparison of soft tissue balancing, femoral component rotation, and joint line change between the gap balancing and measured resection techniques in primary total knee arthroplasty
BACKGROUND This meta-analysis was designed to compare the accuracy of soft tissue balancing and femoral component rotation as well as change in joint line positions, between the measured resection and gap balancing techniques in primary total knee arthroplasty. METHODS Studies were included in the meta-analysis if they compared soft tissue balancing and/or radiologic outcomes in patients who ...
متن کاملThe Effects of Neuromuscular Blocking Agents in Soft Tissue Balancing During Primary Total Knee Arthroplasty
We present a case of elective total knee arthroplasty where the surgical procedure was affected by the neuromuscular blocking agent administered at induction of general anaesthesia. Recognition of this effect was vital to avoid additional bone resection at the soft tissue balancing stage of the procedure.
