The Incidence and Short Term Functional Effect of Partial PCL Release in Fixed and Mobile Bearing PCL Retaining TKA.

Posterior cruciate ligament (PCL) release may be required to balance the flexion gap in PCL retaining TKA. This study examines the incidence and functional consequences of PCL release in both fixed and mobile bearing TKA. A consecutive series of 1388 TKAs with 1014 fixed bearing, and 374 mobile bearing implants were reviewed for prevalence of partial PCL release, restoration of potential flexion and objective knee stability at minimum one-year follow-up.

Synovial fluid differential cell count in wear debris synovitis after total knee replacement.

Background: Determining the cause of synovitis following total knee arthroplasty (TKA) can be challenging. The differential diagnoses include infection, hemarthrosis, instability, crystalline disease, wear debris or idiopathic causes. Wear particle synovitis can mimic periprosthetic infection with symptoms of pain and effusion.

Effect of initial tibial resection thickness on outcomes of revision UKA.

The frequency of unicompartmental knee arthroplasty (UKA) procedures has increased rapidly over the past decade. Some conflicting evidence exists concerning UKA revision. Some studies have found UKA revisions to be comparable with primary total knee arthroplasty, whereas others have found that UKA revisions require a higher need for tibial stems and augments and have more complications and worse results.
