Triathlon Posteriorly Stabilized (PS) Total Knee System - Outcomes Study

2014-08-27 03:20:08 | BioPortfolio

Summary

The purpose of this study is to evaluate the clinical outcomes (range of motion, pain, function, radiographic stability, and health related quality of life) of patients receiving the Triathlon Posterior Stabilized (PS) Total Knee System. These outcomes will be evaluated using pre-operative scores and comparing them to post-operative scores in addition to being compared with cases who received the Scorpio PS implant in the Scorpio IDE study.

Description

Primary total knee arthroplasty has consistently shown to be successful in relieving pain and improving function for those experiencing difficulties of degenerative joint disease. In recent years, patient quality of life and return to function have become of greater importance in assessing the success of joint replacement. While essential functions such as walking and stair climbing are of obvious importance in outcomes, patients also expect to return to other daily activities such as shopping, household duties and gardening, to name a few. While knee replacement to date has demonstrated improvement in standard clinical results, studies have shown an increase in the prevalence of knee symptoms when patients were asked about activities that placed greater load on the extremity (i.e. carrying shopping bags), or demanded increased knee flexion (i.e. gardening, kneeling, squatting). Some literature has indicated that the component design (cam - post interactions in posterior stabilized knees and impingement of the posterior aspect of the tibial insert against the posterior aspect of the femur in cruciate retaining knees) has contributed to the patient's inability or discomfort in performing more demanding activities of daily living.

The Triathlon Knee System has been designed with these activities in mind and this study will evaluate the clinical outcomes(range of motion, pain, function, radiographic stability, and health related quality of life) of patients receiving the device.

Medical and Biotech [MESH] Definitions

A strong ligament of the knee that originates from the anterolateral surface of the medial condyle of the femur, passes posteriorly and inferiorly between the condyles, and attaches to the posterior intercondylar area of the tibia.

Rebuilding of the POSTERIOR CRUCIATE LIGAMENT to restore functional stability of the knee.

The part of the hypothalamus posterior to the middle region consisting of several nuclei including the medial mamillary nucleus, lateral mamillary nucleus, and posterior hypothalamic nucleus (posterior hypothalamic area). The posterior hypothalamic area is concerned with control of sympathetic responses and is sensitive to conditions of decreasing temperature and controls the mechanisms for the conservation and increased production of heat.

The infratentorial compartment that contains the CEREBELLUM and BRAIN STEM. It is formed by the posterior third of the superior surface of the body of the sphenoid (SPHENOID BONE), by the occipital, the petrous, and mastoid portions of the TEMPORAL BONE, and the posterior inferior angle of the PARIETAL BONE.
