Arthrofibrosis in Robotic Total Knee Arthroplasty: An Investigation Into How Robotic Assistance May Contribute to a Tight Knee.

Introduction: Arthrofibrosis after total knee arthroplasty (TKA) can lead to pain and restricted range of motion. Matching native knee kinematics is crucial in avoiding arthrofibrosis postoperatively. However, manual jig-based instruments have demonstrated variability and inaccuracy during primary TKA.

Cefadroxil-Induced Infection Following Total Knee Arthroplasty.

Perioperative infection prophylaxis is a fundamental element of total knee arthroplasty (TKA). There has been a recent trend toward the use of extended postoperative oral antibiotics in high-risk patients. We describe a case report of a patient who underwent a primary TKA and subsequently developed  colitis after an extended course of postoperative prophylactic oral cefadroxil.

Learning Curve of Robotic-Assisted Total Knee Arthroplasty for Non-Fellowship-Trained Orthopedic Surgeons.

Background: Total knee arthroplasty (TKA) serves as a reliable treatment option for patients with end-stage arthritis, but patient dissatisfaction rate remains high. With the projected increase in the volume of arthroplasty operations, surgeons have aimed for methods in which to improve the patient outcomes. Robotic-assisted TKA has become increasingly popular.

Improving Postoperative Acute Kidney Injury Rates Following Primary Total Joint Arthroplasty.

Background: Perioperative hip and knee arthroplasty complications remain a significant clinical and financial burden. Our institution has shifted to developing protocols to decrease these perioperative complications. This study focuses on acute kidney injury (AKI) rate status post primary total joint arthroplasty (TJA).

The UniSpacer: a treatment alternative for the middle-aged patient.

The UniSpacer is a metallic tibial hemiarthroplasty for treatment of isolated osteoarthritis of the medial compartment of the joint. It is a mobile-bearing, self-centering shim that is introduced into the knee through a limited medial arthrotomy without requiring bone cuts or fixation to the tibia or femur. Clinical data are now available that define the efficacy of the procedure in addition to defining the ideal clinical setting for its use in the treatment of osteoarthritis of the medial compartment of the knee.

Unicompartmental tibial hemiarthroplasty: early results of the UniSpacer knee.

An intra-articular metallic spacer is evaluated for the treatment of isolated medial compartment OA. It is proposed that this implant can provide axial correction for a varus deformity, eliminate the pseudolaxity of the MCL, improve knee function, maintain ROM, and provide pain relief. One-and 2-year data are presented on 71 UniSpacer Knee System implants that were implanted in 67 patients (four had bilateral surgeries).

The UniSpacer Knee System: have we been there before?

Tibial hemiarthroplasty using the UniSpacer Knee System is a viable treatment alternative for knee osteoarthritis of the medial compartment. Improvements in patient selection, surgical technique, and rehabilitation continue to improve results. In contrast to alternative procedures, implantation of the UniSpacer Knee System preserves the natural knee anatomy therefore future knee procedures are not compromised.
