The surgical treatment of severe preoperative fixed deformity at total knee arthroplasty involves the appreciation of several basic principles. First, and most obvious, is the fact that fixed deformity means that the soft tissues about the...

Questions/purposes We compared the functional scores in patients with iatrogenic injury to the medial collateral ligament (MCL) treated with additional constraint to those without.
Conclusions Recognition of MCL injury during TKA is crucial, since using nonstabilizing inserts was associated with residual instability requiring revision.
Management of Intraoperative Medial Collateral Ligament...

Questions/purposes We asked whether single-stage revision and direct antibiotic infusion for infected TKA would control infection in patients with methicillin-resistant Staphylococcus aureus (MRSA) infections.
Conclusions One-stage revision and 6 weeks of intraarticular vancomycin administration controlled infection in MRSA infected TKA with no apparent complications.
Methicillin-resistant Staphylococcus aureus in TKA Treated...

Mercy Hospital’s Live Surgery Webcast Will Feature Mini-Incision Surgery for Total Knee Replacement Mercy Hospital’s surgical team will showcase a new advanced technique for total knee replacement (TKR), during a live webcast on Tuesday, October 28, at 5 pm EST. Because of its minimally invasive nature this procedure’s recovery time has...

Operative Technique 9 min video - Wave - Partial Patellofemoral Joint Replacement By: Andreas B. Imhoff

Is it an Option? Edward T. Habermann, MD & Mark Kerner, MD
Total knee replacement is one of the most consistently successful procedures in orthopaedics today, with less than a 5% expected complication rate in primary situations with modern resurfacing techniques. Among these complications, over half are associated with the patella. Resurfacing...

Questions/purposes The purposes of this study were to (1) evaluate the effect of resecting the popliteus tendon on knee ligament balancing in extension and flexion intraoperatively during posterior stabilized TKA; and (2) evaluate the effect of resecting the popliteus tendon on load distribution on the tibial plateau as determined...

2- to 5- Year Follow-up Study of 100 Knees Kenneth A. Greene, M.D., Michael R. Magoline, M.D, and Vincent Ripepi, DO
Abstract: This prospective study analyzed the data from 100 primary total knee arthroplasties performed on 79 patients using the Duracon total knee arthroplasty system.

The effect of total knee arthroplasty on proprioception, kinesthesia, and postural control remains controversial. It is argued that retaining the posterior cruciate ligament may help to preserve these sensorimotor functions and improve the longevity of the prosthesis and the functional outcome. We performed a prospective, randomized study to assess proprioception, kinesthesia, and balance...

Intraoperative frozen section (FS) consultation is used in evaluating possible infection in cases of hip and knee revision arthroplasty, serving as an adjunct to preoperative and intraoperative studies. We examined our experience for more than 11 years to determine if FS examination had value when sections were sent unselectively. As...

Study Protocol
The objective of this study is to determine whether the patient's perceived outcome and speed of recovery differs between a posterior cruciate retaining total knee arthroplasty and a posterior stabilized total knee arthroplasty.
This randomised controlled study has been designed to determine whether the patient's perceived outcome and speed of...

Provides a presentation of knee fusion, patellar resurfacing, patellar complications and knee rehabilitation. Reviews the characteristics of the forces which are transmitted across the knee during its normal use in performing the activities of daily living. Johns Hopkins University.

We studied the histology of the cement-bone interface and the regenerated synovium in ten aseptically loosened arthroplasties in rheumatoid patients. In two patients we found rheumatoid nodules at the cement-bone interface and marked lymphoplasmacytic infiltration in another three. Failed joints in osteoarthritic patients did not show these changes, and it...

Decreasing proprioception of the knee is multifactorial and is a function of age and degenerative joint disease. Soft-tissue release during total knee replacement may have an influence. We have quantified soft-tissue imbalance at the time of knee replacement and attempted to eliminate it at full extension, using established methods. We studied the influence of residual soft-tissue imbalance on...
