Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study is designed as a prospective, multi-center, controlled, non-randomized, clinical investigation to compare the efficiency of TruMatch® Personalized Solutions surgical technique compared to conventional surgical technique.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

Description

Inclusion Criteria:

  • 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, in the opinion of the Clinical Investigator, is able to understand this clinical investigation, and co-operate with investigational procedures.
  • Subject, who, in the opinion of the Clinical Investigator, are suitable for implantation using TruMatch™ instrumentation. For example, no femoral nails/bone plates that extend into the knee, ie. 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 contracture are consistent with TruMatch™ instrumentation.

Exclusion Criteria:

  • The Subject is a woman who is pregnant or lactating.
  • 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) of the affected knee.
  • The Subject requires simultaneous bilateral total knee replacements.
  • The Subject had a contralateral TKA and that knee was previously entered in the study.
  • Subject in whom the surgeon intends to implant a knee prosthesis that is not in the PFC Sigma primary knee system.
  • Subject who has inflammatory arthritis.
  • Subject who has a Body Mass Index (BMI) of ≥ 40. (Please see Table 2-1: Definition of Terms, for BMI definition and calculation formulas).

Active Comparator: TruMatch® Personalized Solutions
Cruciate Retaining and Posterior Stabilized Fixed-Bearing or Rotating Platform Total Knee Arthroplasty (PFC Sigma System) implanted using TruMatch® Personalized Solutions (Custom Patient Instrumentation)
Other: Custom Patient Instrumentation
TruMatch® Personalized Solutions is the brand name of DePuy Orthopaedics, Inc. custom patient instrumentation (CPI). TruMatch™ is a pair of custom-made cutting blocks that allow distal femoral and proximal tibial cuts to be made according to a predefined surgical plan. The inner surface of the femoral block is manufactured to match the geometry of the patient's distal femur. The inner surface of the tibial block is manufactured to match the patient's proximal tibia. The geometric data is obtained from a CT scan and a preoperative plan approved by the surgeon

Other: Conventional Instruments
Total Knee Arthroplasty implanted using conventional instruments (non-CPI) and surgical technique.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
