Knee Replacement clinical trials at University of California Health

7 in progress, 6 open to eligible people

  • Antibiotic Prophylaxis in Patients Undergoing Elective TKA- Multi-center Trial

    open to eligible people ages 18 years and up

    The Antibiotic Prophylaxis in Patients Undergoing Elective Total Knee Arthroplasty (TKA): Multi-Center Trial is a study that will compare the effectiveness of various perioperative strategies for antibiotic delivery as prophylaxis for periprosthetic joint infections (PJI) and surgical site infection in elective primary TKA. The investigators hypothesize that a single dose of prophylactic antibiotic administered within 60 minutes before the incision is not an effective way to prevent PJI in elective primary total knee arthroplasty (TKA). The investigators also hypothesize that the prolonged delivery (24 hours) of antibiotic prophylaxis after surgery does not further reduce the incidence of PJI in elective primary TKA. Duke University is the only site recruiting both primary total knee arthroplasty and unilateral knee arthroplasty.

  • Dexamethasone in Total Knee Arthroplasty

    open to eligible people ages 18 years and up

    The purpose of this study is to determine the most efficacious and safest dexamethasone dose given intraoperatively during total knee arthroplasty that reduces postoperative opioid consumption and pain, improves postoperative nausea and vomiting, and minimizes postoperative complications.

  • Does Single Injection Adductor Canal Block Improve Postoperative Analgesia in Patients Receiving Periarticular Local Anesthesia Injections for Total Knee Arthroplasty?

    open to eligible people ages 18 years and up

    The purpose of the study is to determine the effect of a single injection adductor canal block (ACB) on pain scores within 24 hours post total knee arthroplasty (TKA).

  • iPACK Block With Dexamethasone For Total Knee Replacement

    open to eligible people ages 18 years and up

    Comparing the pain control outcomes for patients undergoing total knee arthroplasty (TKA) with either: 1) adductor canal single shot injection plus placebo iPACK injection or 2) adductor canal single shot injection plus bupivacaine and dexamethasone iPACK injection. There are two surgical approaches for TKA 1) open 2) ROSA robotic assisted. Both follow the same pain management pathway. We plan to enroll patient undergoing either surgical procedure.

  • The Use of Venlafaxine in Reducing Pain in Primary Total Knee Replacement

    open to eligible people ages 18-75

    Patients experience pain after their knee replacement surgery - and some may continue to experience persistent pain long after their knee replacement surgery. Traditional pain management strategies reply on pain medication such as opioids for pain control. However, these drugs do not work well for pain associated with movement or the the nerve pain (tingling, electrical sensations) after surgery. In addition, opioids are associated with significant side effects such as nausea, vomiting, respiratory depression, depression, cognitive dysfunction and risk of persistent opioid use. Neuropathic pain medications, such as venlafaxine are effective in managing nerve pain. Recent studies also support its potential role in acute pain management. Here, we propose a prospective randomized clinical trial 1) to evaluate the efficacy of Venlafaxine in reducing pain intensity and opioid consumption at post-operative day 1 (POD1) and 1- week after surgery, and 2) to examine whether the use of Venlafaxine will reduce the incidents of chronic postsurgical pain in TKA patients at 3-month time point.

  • Treatment of Post-Operative Pain Following Orthopedic Surgery With SPRINT® Peripheral Nerve Stimulation (PNS) System

    open to eligible people ages 21 years and up

    The purpose of this study is to gather information about how knee pain changes when small amounts of electricity are delivered to the nerves in the leg. This study will involve the use of a Peripheral Nerve Stimulation (PNS) System that is made by SPR Therapeutics (the sponsor of the study). The SPRINT PNS System was cleared by the FDA for up to 60 days of use in the back and/or extremities for the management of acute and chronic pain.

  • A Multicenter Study to Evaluate Functional Outcome After Knee Replacement

    Sorry, in progress, not accepting new patients

    Patients will be consecutively enrolled by implant. Implant groups will be those who have undergone surgery with either a ConforMIS iTotal® CR TKA or an Off-the- Shelf (OTS) system. The patient will conduct functional testing and answer questionnaires. The results will compare the ConforMIS iTotal with an Off the Shelf Knee replacement.
