Posterior Direction

Prosthetic total knee replacements rarely dislocate. When dislocation does occur, it is usually in a posterior direction in association with a posterior stabilised, cruciate-sacrificing prosthesis. Neurovascular injury is unusual. In this report, we describe a case of anterior dislocation of a cruciate-retaining total knee replacement in a 67-year-old woman. The dislocation occurred in the absence of overt trauma and resulted in severe neurovascular injury.

Patella Tracking

Rotating platform total knee replacement implants have been marketed to allow more precise approximation of normal knee kinematics and enhance patella tracking. At liberty of rotation, the distinct mobile polyethylene insert design does have its pitfalls in spite of purported merits. We report a case of lateral knee pain following rotating platform total knee replacement, attributable to iliotibial band impingement by the rotating polyethylene insert. Prompt treatment via arthroscopic release circumvented a traumatic and costly revision procedure.

We analyzed the kinematics of two rotating platform total knee replacement designs using KneeSIM, a commercially available computer code (LifeModeler, San Clemente, CA) in which we could manipulate the location of the axis of rotation of the rotating bearing.

INTRODUCTION The effect of primary total knee replacement on the employment status of 56 patients under 60 years of age was examined at a mean follow-up of 64 months. PATIENTS AND METHODS A total of 56 primary total knee replacements performed on patients under the age of 60 years by two surgeons between 1996 and 2003 were retrospectively assessed by postal questionnaire. Patients were selected from databases held at Holly House and Newham Hospital NHS Trust. RESULTS Overall, 97.5% of patients who were employed before their operation, returned to their previous work. However, in patients not working prior to total knee replacement none were employed after their operation. CONCLUSIONS Total knee replacement may be a valuable tool to help some patients to continue working but may not affect patients who are already unemployed.

A three-year-old intact female Great Pyrenees underwent total knee replacement for the treatment of osteoarthritis. The dog contracted septic arthritis 10 weeks following the procedure. Treatments including implant subtraction, debridement of tissue, and insertion of bone cement with antibiotics into the joint space were completed in the joint cavity. A temporary external skeletal fixator was used to stabilise the joint for four weeks. A second attempt at total knee replacement failed due to severe muscle contracture and bone loss. Therefore, it was decided to perform arthrodesis as a salvage procedure. At the 17 month follow-up examination, the patient was able to use the limb while standing and at all gait speeds. Based on these findings, two-stage arthrodesis can be a viable salvage procedure for infected total knee replacements.

Objectives: This paper will look at the incidence of Total Knee Replacement in patients over the age of 50 years over an 8 year period. All patients had a symptomatic medial meniscal tear and moderate bi-compartmental osteo-arthritis. Hypothesis: Incidence of Total Knee Replacement in these patients increases with age and length of follow up. Methods: A total of 411 patients met this criteria with 357 contactable by telephone. Patients were asked regarding Total Knee Replacement and other surgical intervention. Results: Of the total of 357 patients contacted, 78 (22%) patients were referred for Total Knee Replacements over this 8 year period. Conclusion: The incidence of Total Knee Replacement correlates with age but not with follow up.

Having demonstrated in Chapter 2 that a fully conforming mobile bearing can minimise polyethylene wear, in this chapter we show that a mobile bearing prosthesis, unconstrained in the sagittal plane, can restore natural mobility and stability. For surgeon readers who are less interested in the theoretical background, it might be advisable to go straight to Chapter 4, Indications, or to start by reading the final section of this chapter, The Loaded Prosthetic Knee. If that proves interesting, the surgeon might attempt The Unloaded Prosthetic Knee. For the more research minded surgeon or engineer, it seems more logical to start with the Unloaded Natural Knee (the longest section of the chapter) and to read from there. The chapter may also be of interest to those surgeons embarking on the use of a bi-cruciate retaining total knee replacement.
