Total Knee Arthroplasty Surgical Protocol

All surgical procedures were performed by one of three surgeons (IT, ST, and MW) using spinal anesthesia with 2.4 to 3.2 mL of 0.5% bupivacaine (Marcaine; AstraZeneca). We did not use the pneumatic tourniquet or drain for any patients. Anteromedial straight skin incision of 4 cm proximal to the superior patella to 1 cm distal to the tibial tuberosity was made, and subvastus approach were used in all surgeries. All patients received a cemented, posterior stabilized prosthesis (Scorpio NRG; Stryker Orthopedics, Mahwah, NJ, USA).
The postoperative rehabilitation regimens were the same for both groups and were started from 1 day after surgery in the afternoon.

Standardized Knee Replacement Procedures

One surgery team performed all operations. The SR prostheses were Scorpio NRG (Stryker Orthopedics, Mahwah, NJ, USA) and the SR prostheses were Sigma PFC (DePuy Orthopedics, IN, USA). All K-L (Kellgren-Lawrance) arthritis grades of the patients were in grade IV. A medial parapatellar approach was used. Distal femoral osteotomies were usually 6° to the femur anatomic axis [19 (link)]. Femoral rotational alignment was performed according to the epicondylar axis, usually 3° of external rotation from the posterior condylar line. Both groups removed the posterior cruciate ligaments (PCL). Femoral components were similar size (standard size) in both designs, and the cemented tibial baseplates were also similar in both designs. Patellar resurfacing was not utilized in either group. All components were cemented. All patients were given cephalosporin for 24 h to prevent infection. A plasma drainage tube was used for 24 h. Continuous movement exercises were started postoperatively to recover quadriceps strength.

Total Knee Arthroplasty Surgical Protocol

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

All surgeries were performed by one of the 2 surgeons (S.T. and M.W.). Neither a pneumatic tourniquet nor drain was used in any of the patients undergoing TKA during the study period. A subvastus approach was used in all surgeries except in patients with valgus knees, for whom a lateral approach was used. All patients received a cemented, posterior stabilized prosthesis (Scorpio NRG; Stryker Orthopaedics, Mahwah, NJ).
We administered 1 g of tranexamic acid intravenously (Transamin; Daiichi Sankyo, Tokyo, Japan) just prior to skin incision and again at 6 hours after the first administration.
We subcutaneously administered 1.5 or 2.5 mg of fondaparinux (Arixtra; GlaxoSmithKline, Tokyo, Japan) for thromboprophylaxis once every evening for 10 days, starting from postoperative day 1. The dosage was determined based on the renal function and body weight.
For postoperative pain control, intraoperative periarticular injection including ropivacaine, morphine, epinephrine, ketoprofen, and/or corticosteroid was performed [14] (link), [15] (link). From the day after surgery, oral nonsteroidal anti-inflammatory drug (60 mg of loxoprofen, Surinofen; Aska, Tokyo, Japan) was administered 3 times a day.
An intravenous cefazolin (Cefamezin; Astellas, Tokyo, Japan) was administered perioperatively and every 8 hours for the first 48 hours after surgery.

All patients had a spinal anaesthetic using 2.0 mL to 2.8 mL
of 0.5% bupivacaine (Marcaine, AstraZeneca, Osaka, Japan).
All operations were carried out by one of two surgeons (ST and
MW). Neither pneumatic tourniquet nor drain was used during the
study period. A subvastus approach was used in every case. All patients
had a cemented, posterior stabilised prosthesis (Scorpio NRG, Stryker
Orthopaedics, Mahwah, New Jersey) implanted.
The post-operative rehabilitation regimen was the same for both
groups, and started the day after surgery.

TXA Application in Total Knee Arthroplasty

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

All TKAs were performed by two senior surgeons with the same surgical principle and prosthesis (Scorpio NRG, Stryker, Mahwah, NJ, USA). In the TXA group, 3.0 g of TXA in 100 mL of saline solution was applied directly into the knee joint cavity while suturing. An intra-articular drain was left for 48 h postoperatively. After the removal of drains, a range of motion exercise and walker-aided ambulation were encouraged. For DVT prophylaxis, intermittent pneumatic compression device was routinely used and a low molecular weight heparin was injected for 1 week after surgery [26 (link),27 (link)]. There was no long-term anticoagulant therapy, regardless of the groups.

All TKA procedures were performed by senior surgeons using an air tourniquet and a medial parapatellar approach under spinal or general anesthesia, at the discretion of the anesthesiologist. The following types of implants were used: cruciate-retaining cemented implant (Vanguard Knee System [Zimmer Biomet, Indiana, USA]); posterior-stabilized cemented implant (Bi-Surface Total Knee System [Kyocera, Kyoto, Japan], NexGen LPS-Flex Knee [Zimmer Biomet, Indiana, USA], Persona [Zimmer Biomet, Indiana, USA], Scorpio NRG [Stryker, Michigan, USA], or Triathlon Total Knee System [Stryker, Michigan, USA]); or a posterior-stabilized cementless implant (Triathlon Total Knee System [Stryker, Michigan, USA]).

The procedure was modified to about 20° of horizontal incision than the traditional midvastus approach. The distal femoral cut was performed by intramedullary guide in the alignment at 6° of valgus. Whiteside's line and posterior condyle axis (PCA) were used as guides to adjust position for the optimal femoral external rotation. The proximal tibia was cut perpendicular to the mechanical axis using an extramedullary alignment guide. Two types of TKA prosthesis were used, including the former half of duration (18 × 3 months) with Scorpio NRG (Stryker Orthopaedics, USA) and the latter half of duration with NexGen High Flex (Zimmer Inc., USA). After components were cemented-implanted, joint stability and implant position were rechecked. After the surgery, the cutting thickness of each bone fragments was recorded.

A total of 98 OA knees in 86 consecutive patients scheduled for primary TKA from January 2007 to August 2008 at Oe -kyodo hospital were assessed in this study. Patients with a history of osteotomy of the affected knee, valgus deformity or rheumatoid arthritis were excluded. Subjects were 67 women and 19 men with a mean age of 74.6 years (range, 60 -88 years). Subject characteristics are summarized in Table 1. All cases were treated with standard cruciate-retaining TKA or posterior-stabilized TKA [Scorpio NRG (Stryker, Kalamazoo, MI), NexGen (Zimmer, Warsaw, IN)] using the navigation system. The relevant institutional review boards reviewed and approved the study protocol, and each patient provided informed consent to participate.

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.
