چکیده

BACKGROUND There is no consensus regarding the use of retaining or replacing cruciate implants for patients with limited deformity who undergo a total knee replacement. Scope of this paper is to evaluate whether a cruciate sparing total knee replacement could have a reduced operating time compared to a posterior stabilized implant. METHODS For this purpose, we performed a randomized study on 50 subjects. All procedures were performed by a single surgeon in the same conditions to minimize bias and only knees with a less than 20 varus deviation and/or maximum 15° fixed flexion contracture were included. RESULTS Surgery time was significantly shorter with the cruciate retaining implant (P = 0.0037). The mean duration for the Vanguard implant was 68.9 (14.7) and for the NexGen II Legacy was 80.2 (11.3). A higher range of motion, but no significant Knee Society Scores at 6 months follow-up, was used as controls. CONCLUSIONS In conclusion, both implants had the potential to assure great outcomes. However, if a decision has to be made, choosing a cruciate retaining procedure could significantly reduce the surgical time. When performed under tourniquet, this gain does not lead to reduced blood loss.

Conservative Bone Cuts and Technical Hints Incruciate Retaining Total Knee Arthroplasty, a 20 Years Experience

Total knee arthroplasty (TKA) is one of the most successful procedures in modern orthopedic surgery, providing high patient satisfaction rate. As a result, the number of patients undergoing TKA is increasing in number every year and more patients would be inclined to have the operation in near future . The demand for TKA is expected to grow 673% between 2005 and 2030. Knee surgeons are using mo...

Comparison of 2 polyethlene inserts for a new cruciate-retaining total knee arthroplasty prosthesis.

Cruciate-retaining total knee arthroplasty has had high success rates but does not always have optimal functional outcomes. The purpose of this study was to compare 2 polyethylene inserts of varying constraint that were used in a new cruciate-retaining total knee arthroplasty design to determine whether differences were found in clinical or functional outcomes. The use of the newer cruciate-ret...

Kinematic gait parameters changes in patients after total knee arthroplasty. Comparison between cruciate-retaining and posterior-substituting design.

PURPOSE The patients expect optimal knee function after Total Knee Arthroplasty. It is necessary to apply appropriate surgical technique and supervised physical therapy. The optimal management of posterior cruciate ligament remains controversial. Both implant designs, i.e., cruciate retaining and posterior substituting, allow the orthopedic surgeon to achieve excellent clinical outcomes, as mea...

The utility of bicruciate-retaining total knee arthroplasty

BACKGROUND We describe the features of modern and historical bicruciate-retaining (BCR) total knee arthroplasty (TKA) implants compared with other TKA implant designs, reviewing kinematics, proprioception, operative technique, and clinical results. METHODS We performed a review based on PubMed, Embase, CINAHL Plus, and Cochrane databases from January 1990 to April 2016 using combinations of t...

The influence of tourniquet use and timing of its release on blood loss in total knee arthroplasty.

In surgical practice, hemostasis is used to minimize postoperative bleeding in total knee arthroplasty. We performed a prospective randomized study to determine the influence of tourniquet use and the timing of its release on amount of bleeding. Eighty four patients (96 knees) were scheduled for total knee arthroplasty and randomly divided into three groups. Posterior cruciate retaining bicompa...
