Digital three-dimensional models of six contemporary TKA femoral component design families from various manufacturers were assessed in this study: (1) Design A: Persona™ The Personalized Knee System (Zimmer, Warsaw, IN); (2) Design B: NexGen^® Complete Knee Solution (Zimmer, Warsaw, IN); (3) Design C: Sigma^® Knee Solutions (DePuy Synthes, Warsaw, IN); (4) Design D: GENESIS™ II Total Knee System (Smith and Nephew, Memphis, TN); (5) Design E: Triathlon^® Knee System (Stryker, Kalamazoo, MI); and (6) Design F: Vanguard^® Complete Knee System (Biomet, Warsaw, IN) (Table 2). Designs A and B have multiple ML size offerings for a specific component AP size. Design A has both standard and narrow ML offerings per AP size, with the finest increment (2 mm) selection in AP sizes amongst all the design families. Design B offers standard and gender sizes in ML widths, each comes with standard and minus sizes in AP dimension. Designs C–F have single ML offerings across component AP size. All available sizes and ML offerings in the design families were included in this study.Table 2

Total Knee Arthroplasty Surgical Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols

All TKAs were performed by a senior surgeon (KIK) in a single institute. A pneumatic tourniquet was applied during the operation and deflated before wound closure. Cemented components were used in all cases. The prosthesis used was the posterior-stabilized Attune Knee System (Depuy Synthes, Warsaw, IN) in 144 knees, the Truliant Knee System (Exactech, Gainesville, FL, USA) in 56 knees, the Triathlon Knee System (Stryker, Mahwah, NJ, USA) in 40 knees. The patella was resurfaced in all cases. Perioperative TXA administration was applied according to the protocol determined for each group. A suction drain was placed into the knee joint and opened without clamping. The trigger for transfusion was a postoperative hemoglobin level lower than 8.0 g/dL with clinical symptoms of anemia any time during the postoperative period [30 (link)]. An elastic stocking and intermittent pneumatic compression device were applied after surgery. All patients received the same postoperative rehabilitation. This included range of motion, calf pump exercises, straight leg raising, and bedside continuous passive mobilization on postoperative day 1. The suction drain was removed 24 hours postoperatively, and patients were allowed to walk as tolerated.

From October 2011 to March 2015, 35 investigators across 22 sites (from the United States, United Kingdom, Australia, and New Zealand) consented and enrolled 843 subjects (843 primary TKA) across all 4 configurations (211 CR FB, 210 CR RP, 212 PS FB, 210 PS RP) with a combination of currently available products: 3% NexGen Complete Knee Solution (Zimmer, Warsaw, IN), 7% Triathlon Knee System (Stryker, Kalamazoo, MI), or 90% P.F.C. SIGMA Knee System (DePuy Synthes, Warsaw, IN). Surgeons implanted the knee and configuration per their standard practice. This cohort was registered on www.clinicaltrials.gov under registration number: NCT01497730.

Knee Joint Imaging and Arthroplasty Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols

Before surgery, the knee of each specimen was CT scanned (SOMATOM Definition Flash; Siemens Healthcare) including 15 cm proximal and distal to the joint line. The scans were carried out using a standard protocol with axial slices at a peak voltage of 120 kVp and exposure of 183 mAs, slice thickness of 0.6 mm, slice increment of 1 mm and pixel spacing of 0.29 × 0.29 mm. The effective dose of the CT was estimated to 0.095 mSv. Subsequently, all specimens were disarticulated at the hip and ankle joints and the proximal femoral and distal tibial bone were dissected for soft tissue to ensure a rigid fixation of the specimen. Approximately 8–13 tantalum beads (X‐medics) were inserted through a 4 mm drill hole in the cortical bone of the distal femoral and proximal tibial bones using a bead gun (Kulkanon; Wennbergs Finmek AB). Beads were placed in a systematic pattern intending a wide‐spread 3D marker distribution. We used a standard operative total knee arthroplasty procedure according to the manufacturer's guidelines²¹ with an anterior midline incision and medial parapatellar arthrotomy. All specimens received the cemented (Palacos®R + G, Heraeus, Medial GmbH, 61273) Triathlon® Knee System (Stryker) for the femur, tibia, and patella in size ranges of four to six. One experienced knee arthroplasty surgeon performed the surgical procedures on all specimens.

Navigated versus Conventional TKA

Check if the same lab product or an alternative is used in the 5 most similar protocols

A total of 148 consecutive TKAs were performed in 130 patients using the Triathlon Knee System (Stryker, Mahwah, NJ, USA) from July 2005 to December 2007. The patients were followed for at least 50 months postoperatively. The patients included had primary or secondary osteoarthritis. Exclusion criteria were: bone graft due to severe deformity or bone defect, revision surgery, infected TKA, male patients. In addition, patients who had fixed flexion contracture > 20° were excluded because that deformity could influence the zero setting of the navigation system. The Triathlon Knee System cuts bone using a posterior referencing system; the anterior flange angle of the femoral component was changed from 3° to 7° to reduce anterior femoral notching.
Seventy knees (62 patients) underwent conventional TKA in a retrospective case control study. Seventy-eight knees (68 patients) underwent navigated (ver. 3.0 Stryker Orthopedics, Kalamazoo, MI, USA) TKA. The clinical data of sex, age, follow-up period, bone mineral density (BMD), bone mass index (BMI), and preoperative varus deformity between the conventional TKA and navigated TKA groups are compared in Table 1. These parameters were matched between the groups.

Standardized Knee Replacement Rehabilitation

Check if the same lab product or an alternative is used in the 5 most similar protocols

All patients underwent the same surgical procedure. All implants used were Triathlon® Knee System (Stryker corp NJ, USA). The anesthesia method was general anesthesia with nerve block or epidural block.
Physical therapy was performed the day before surgery and preoperative evaluation was performed. Physical therapy resumed the day after surgery, and continued every day, except Sunday. The intervention time was 20 to 40 minutes per day, and several physiotherapists from the orthopedic team provided intervention for each patient. Full load was allowed from the day after surgery, and range of motion (ROM) training, muscle strengthening training, basic movement training, and walking training were carried out step by step. The final evaluation was performed at the time of the final physical therapy before discharge, and this was used as the evaluation at discharge.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
