Osteoarthritis Clinical Trials in Chicago, IL

The proposed research study aims to evaluate the effects of autologous bone marrow aspirate concentrate (BMAC) on the development and progression of osteoarthritis (OA) in patients undergoing meniscectomy. This prospective, randomized, double-blind clinical trial will compare patient-reported outcomes, specifically IKDC scores between patients who receive BMAC post-meniscectomy and those who receive a saline control injection. The study will also compare physical examination, MRI, radiographs, and synovial fluid analysis. Our hypothesis is that those who receive the autologous BMAC injection after the procedure will have better outcomes than those who do not. Read Less

The goal of this clinical trial is to evaluate the safety and effectiveness of the Polymotion Hip Resurfacing (PHR) System compared to total hip arthroplasty, for adults who require hip resurfacing arthroplasty due to 1) non-inflammatory arthritis (degenerative joint disease) such as osteoarthritis, traumatic arthritis, or 2) mild dysplasia/developmental dislocation of the hip (DDH) up to Crowe Grade 1.

The main objective of this study is to evaluate the safety, performance, and clinical benefits of the Persona Keel cementless and cemented knee. Read Less

This multicenter, prospective, interventional trial is designed to assess the outcome of subjects with symptomatic knee osteoarthritis (OA) that are randomized to treatment with either genicular artery embolization (GAE) using Embosphere Microspheres or steroid injection over a period of 24 months.

The objectives of this study are to confirm the safety, performance, and clinical benefits of Zimmer Biomet Shoulder Arthroplasty Systems and its instrumentation in primary or revision shoulder arthroplasty. These objectives will be assessed using standard scoring systems, radiographic evidence, and adverse event records. Safety of the system will be assessed by monitoring the frequency an incidence of adverse events. Read Less

The purpose of this study is to determine if hip precautions, which are instructions that limit functional use of a hip replacement after surgery, affect the rate of dislocation in the first six weeks after primary total hip replacement surgery. The impact of hip precautions on a patient's return to activities of daily living and overall patient satisfaction will also be investigated. The overall cost effectiveness of hip precautions will be determined. Read Less

Compared to the knee and shoulder, the hip joint leaves relatively little space to maneuver arthroscopic instruments and camera. To expand the potential space in the hip joint, traction is commonly applied to the operative leg through a perineal post. This is an effective technique to improve the working space for arthroscopy, however it has been associated with complications, including perineal numbness. Traction pads, used alone or with a perineal post, can reduce pressure on the perineal area, thus reducing numbness. The investigators hypothesize that positioning hip arthroscopy patients using a traction pad on a standard traction table with a perineal post will reduce the incidence and duration of postoperative perineal numbness.

The purpose of the chronic pain master protocol is to compare independent pain interventions and establish an overarching structure for the disease-state addenda (DSA) and intervention-specific appendices (ISAs). The ISAs may start independently of other ISAs as interventions become available for clinical testing. Read Less

The goal of this study is to create a prospective registry (\<100 patients) to show the effectiveness of the genicular artery embolization procedure overtime in reducing bilateral or unilateral osteoarthritic knee pain as measured by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score.

Thumb carpometacarpal (CMC) osteoarthritis (OA) is common, seen frequently in middle-aged and elderly women. While a variety of surgical treatments have been described with none superior to any other, there is no consensus on the optimal duration of postoperative immobilization. Immobilization following surgery is critical for wound healing, pain control, and aid with activities of daily living in the early recovery period, though the duration of this must be weighed against the negative impacts of immobilization, such as stiffness, contracture, and delay in return to full function. The information gained in this study may allow hand surgeons to use an evidence-based postoperative rehabilitation protocol. Thus, our goal is to compare varying durations of postoperative immobilization after thumb CMC arthroplasty in a randomized trial design. Subjects will be randomized to treatment with non-removable thumb spica plaster postoperative splint immobilization for 2 weeks or non-removable thumb spica plaster splint transitioned to cast for a total of 6 weeks immobilization following base of thumb arthroplasty. Patient-reported outcome measures (PROs) and objective metrics will be tracked in the follow-up period. Read Less

Knee replacement surgery can be performed in one of two ways. Traditionally the goal was for the new joint to be in a neutral position with respect to the femur (thigh bone). This is called Mechanical Alignment (MA). The neutral position is different than the human knee's natural position, so MA often requires the surgeon to make additional cuts to the ligaments and other soft tissue around the knee. More recently surgeons have started to place the new joint in a position that more closely replicates the natural alignment of the human knee. This is called Kinemetic Alignment (KA). KA can be done without additional soft tissue dissection but the procedure requires a higher level of precision that can be difficult to achieve in every case. Some studies have found no difference in outcomes between MA and KA, whereas others have found KA to be superior. But these were small studies or studies that did not consider patient-rated outcomes.
