Primary Outcome Measures:
  • Surgical Procedure Time to Compare Skin-to-Skin Time for Conventional Versus TruMatch® Primary Total Knee Replacements [ Time Frame: Intraoperative ] [ Designated as safety issue: No ]
    Skin-to skin time for conventional versus TruMatch® primary total knee replacements (recorded by Investigator on Operative case report forms).

Secondary Outcome Measures:
  • Operating Room Setup - Operating Room Cleaned up From Previous Case to Surgical Draping Complete [ Time Frame: Intraoperative ] [ Designated as safety issue: No ]
    Operating Room setup time as recorded by video time analysis [minutes]

  • Turnover Time (Time to Clean Operating Room After Surgery is Completed) [ Time Frame: Intraoperative ] [ Designated as safety issue: No ]
    Turnover Time as recorded by video time analysis [minutes].

  • To Compare the Costs Associated With Conventional Versus TruMatch® Total Knee Arthroplasty Surgical Procedures [ Time Frame: Intraoperative ] [ Designated as safety issue: No ]
    Costs associated with surgery.

  • To Compare the Differences in Operating Room Efficiency as a Function of Institution Type and Geographical Location [ Time Frame: Intraoperative ] [ Designated as safety issue: No ]

Groups/Cohorts Assigned Interventions
TruMatch® Personalized Solutions
Cruciate Retaining and Posterior Stabilized Fixed-Bearing or Rotating Platform Total Knee Arthroplasty (PFC Sigma System) implanted using TruMatch® Personalized Solutions
Other: Instrument
TruMatch® Personalized Solutions is the brand name of DePuy Orthopaedics, Inc. custom patient instrumentation. 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 Name: TruMatch® Personalized Solutions
Conventional Total Knee Replacement
Cruciate Retaining and Posterior Stabilized Fixed-Bearing or Rotating Platform Total Knee Arthroplasty (PFC Sigma System) implanted using conventional instruments

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.

Ages Eligible for Study:   18 Years to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Males and females who are appropriate candidates for primary knee replacement between the ages of 18 and 80 years, inclusive, with non-inflammatory degenerative joint disease will be considered for this investigation.

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).
