A Multicenter, Open-Label, Single-Arm, Proof of Concept Study of Pulsed Electromagnetic Field (PEMF) Therapy to Evaluate Synovial Fluid Markers in Subjects with Osteoarthritis of the Knee.

Sponsor: Regenesis Biomedical, Inc.

January 2016 – November 2016

The purpose of this study is to investigate the effect of PEMF treatment when administered twice daily over a 90-day period by looking at synovial fluid in subjects with osteoarthritis of the knee.

New Protocol To Prevent Prosthetic Joint Infection in Hip and Knee Revision Arthroplasty

Primary and revision hip and knee arthroplasty are being performed at an increasing rate.  The number of arthroplasty procedures in the United States is expected to increase to 4 million annually by the year 2030.  With current antibiotic prophylaxis regimens, infection rates for aseptic revision arthroplasty are 2-3 times that for primary cases.  Infection remains the most common cause of failure for both hip and knee revision arthroplasty.  The purpose of this study is to examine a protocol aimed at decreasing the complication rate associated with revision total joint arthroplasty.  This is a retrospective case series of consecutive patients treated by a single surgeon at a community hospital.  All patients underwent a revision hip or knee arthroplasty with the use of the above mentioned protocol.  Preoperative data collection will include patient age, comorbidities, laboratory abnormalities, and functional scores.  Intraoperative data will include the type of procedure, length of surgery, intraoperative culture and pathology findings, estimated blood loss and tourniquet time.  Postoperative data will include length of stay, complications, additional surgeries, need for blood transfusion, wound evaluations, postoperative antibiotic use, measurements of peak and trough as applicable in the immediate postoperative period, renal function based on basic metabolic panel, pain and functional scores.  Data will be compared to published norms.

 

Radlink Leg Length Study

This is a retrospective review of 115 total hip arthroplasties performed through a direct anterior approach, by a single surgeon at a community hospital.   Preoperative data will include the recorded clinical assessment of leg length using blocks, as well as screening for comorbidities and confounding factors such as pelvic obliquity, spinopelvic fusions, and preoperative flexion contracture.
