Alignment Comparison Between TruMatch™ Personalized Solutions and Conventional Total Knee Replacement Instrumentation

Completed · Not applicable

Conditions studied: Osteoarthritis, Knee

In brief

This investigation is intended to provide clinical information about alignment using TruMatch™ and to compare the results to a conventional total knee replacement. TruMatch™ will be compared to a historical control study, which compares alignment results of computer aided surgery (CAS) and conventional surgical techniques. The purpose of this investigation is to determine whether TruMatch™ alignment is non-inferior to alignment achieved with conventional instrumentation. This investigation will compare long leg alignment in total knee replacement achieved by the two types of procedures. Radiographic analysis will be performed by the same independent radiographic reviewer as the historical control study.

• Subjects meeting all of the following specific criteria will be considered for participation in the study:
• Subject is male or female and between the ages of 18 and 80 years old, inclusive.
• Subject requires a primary total knee replacement and is considered by the Investigator to be suitable for the specific knee prosthesis identified in the protocol.
• Subject has given voluntary, written informed consent to participate in this clinical investigation and has authorized the transfer of his/her information to DePuy.
• Subject has given consent to the transfer of his/her information to DePuy.
• Subject, who, in the opinion of the Clinical Investigator at the time of preoperative planning, are suitable for implantation using TruMatch™ instrumentation and whose surgical plan (patient proposal) is approved. For example, no femoral nails/bone plates that extend into the knee, i.e. within 8cm of joint line; no metal device that could cause CT scatter about the knee and no deformities greater than 15 degrees of fixed varus, valgus, or flexion

You may not qualify if…

• The Subject has, in the opinion of the Investigator, an existing condition that would compromise their participation and follow-up in this study.
• The Subject is a woman who is pregnant or lactating.
• The Subject is a known drug or alcohol abuser or has a psychological disorder that could affect follow-up care or treatment outcomes.
• The Subject has participated in a clinical investigation with an investigational product in the last 3 months.
• The Subject is currently involved in any personal injury litigation, medical-legal or worker's compensations claims.
• The Subject has previously had a prosthetic knee replacement device (any type including unicompartmental, total knee arthroplasty, patellofemoral arthroplasty) of the affected knee or a previous patellectomy.
• The Subject presents ankylosis of the hip joint on the side to be treated or previous ipsilateral UTO/HTO.
• The Subject requires simultaneous bilateral total knee replacements.
• The Subject had a contralateral TKA and that knee was previously entered in the study.
