Fate of Two-stage Reimplantation After Failed Irrigation and Débridement for Periprosthetic Knee Infection

Location: http://www.springerlink.com/content/557248l10g1u5405/fulltext.html

Questions/purposes We determined the rerevision rate due to infection after two-stage reimplantation performed for failed irrigation and débridement of infected TKA.
Conclusions The failure rate in this series of two-stage revisions for periprosthetic knee infection in patients treated with previous irrigation and débridement is considerably higher than previously reported...

Hospital Economics of Primary Total Knee Arthroplasty at a Teaching Hospital

Location: http://www.springerlink.com/content/knt85n4p5w76521r/fulltext.html

Questions/purposes The purposes of the current study were to (1) determine revenue, expenses, and profitability (loss) for TKA for all patients and for different payors; (2) define changes in utilization and unit costs associated with this operation; and (3) describe TKA cost control strategies to provide insight for hospitals...

In Vitro Quantification of Wear in Tibial Inserts Using Microcomputed Tomography

Location: http://www.springerlink.com/content/a21731u863447650/fulltext.html

Questions/purposes We developed and validated a technique to quantify polyethylene wear in tibial inserts using microcomputed tomography (micro-CT), a nondestructive high-resolution imaging technique that provides detailed images of surface geometry in addition to volumetric measurements.
Conclusions Micro-CT can provide precise and accurate volumetric measurements in addition to quantifiable three-dimensional...

In Vivo Normal Knee Kinematics

Location: http://www.springerlink.com/content/358351jh741405p8/fulltext.html

Questions/purposes We determined whether different ethnic and gender groups residing in the United States had different knee translations and rotations.
Conclusion We identified small differences in maximum flexion between genders and ethnic groups. While no differences were identified in the lateral condyle translation, the medial condyle remained more stationary...

Instructions For Using The Knee Society Radiographic Evaluation Form

Location: http://www.kneesociety.org/web/outcomes_instructions.html

The Knee Society rating system was first promulgated during the late 1980's and has become the standard clinical evaluation system for reporting results for patients undergoing Total Knee Replacement. Most major journals strongly encourage that total knee manuscripts include Knee Society rating scores as part of the result section. This site...

Intramedullary Arthrodesis of the Knee in the Treatment of Sepsis After TKR

Location: http://www.ncbi.nlm.nih.gov:80/pmc/articles/PMC2504091/

A review of infections following TKR treated at two joint replacement centers identified 29 cases of resistant knee sepsis treated with a long intramedullary fusion nail. Clinical outcome and radiographs were reviewed at an average follow-up of 48 months
Intramedullary arthrodesis is a viable treatment for refractory infection after TKR. Patients...

Knee Arthroplasty With a Medially Conforming Ball-and-Socket Tibiofemoral Articulation Provides Better Function

Location: http://www.springerlink.com/content/t6501256k02g250u/fulltext.html

We asked whether the medially conforming ball-and-socket design differences would be associated with (1) improved ROM; and (2) improved scores compared to a conventional, fixed-bearing posterior-stabilized TKA.
Conclusions Both implant designs similarly relieved pain and improved function. The medially conforming ball-and-socket articulation provided better high-end function as reflected by the...

Knee Fusion for Irretrievably Failed Total Knee Replacement

Location: http://www.aboutjoints.com/physicianinfo/topics/fusionknee/kneefusion.htm

Over the past 30 years, the increasing success of total knee arthroplasty has gradually replaced arthrodesis as the procedure of choice in most conditions causing severe joint destruction. Instead of a primary procedure, arthrodesis is now considered a salvage procedure relegated to cases where total knee replacement may he contraindicated,...

Lateral dislocation of the knee joint after total knee arthroplasty

Location: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2518130/

Case presentation
A 70-year-old woman was referred to our hospital because of right knee dislocation after TKA was performed on her right knee due to severe varus deformity and flexion contracture. This instability was caused by persistent MCL tightness and iatrogenic lateral collateral, arcuate ligament, and popliteus tendon injury.
The torn lateral...

Ligament Balancing in Primary Total Knee Replacement

Location: http://orthonet.on.ca/emergingtrends/notes/Ligament%20Balancing.htm

Benefits to balancing the ligaments: optimize the results, recognize potential errors in bone resection and soft tissue problems intraoperative. It is essential to balance the ligaments if one is to use a mobile bearing type of knee.

Ligamentous Balancing in Rotating-platform Knees

Location: http://www.orthosupersite.com/view.asp?rID=18384

he primary objectives of total knee arthroplasty are to reduce pain, maximize range of motion (ROM), and provide stability through the gait cycle. Pain relief depends on proper ligamentous balancing and solid implantation. Solid implantation is typically assured through cementation, whereas soft-tissue balancing is vital to ensure maximum ROM and...
