Filter by:Many patients with osteoarthritis of the knee fail non-operative measures and elect to have knee arthroplasty to improve their quality of life. If successful, intra-articular mesenchymal stem cell (MSC) injections into the knee may offer another viable non-operative treatment modality. Additionally, this modality may have reparative or regenerative potential, which could lead to the first treatment for osteoarthritis that treats the underlying disease as opposed to symptomatic control. Additionally, there are no acceptable non-surgical treatments for focal chondral defects of the knee. Surgical treatments that do exist have diminished outcomes if performed on patients older than age 30-40 years. If successful, intra-articular MSC injections into the knee would represent the first non-operative treatment for focal chondral defects and also represent a potential option for treatment in patients over the age of 30-40 years. This trial will be a prospective, single-center phase I pilot study to evaluate the safety and tolerability of a single intra-articular injection of autologous bone marrow-derived MSCs in 16 subjects, 8 who have knee osteoarthritis and 8 who have a focal chondral defect in the knee. Patients will undergo a bone marrow harvest procedure at the Dahms Clinical Research Unit (DCRU) of University Hospitals Cleveland Medical Center. MSCs will be isolated and expanded. After approximately 2-3 weeks, patients will return for an intra-articular injection of 50x106 MSCs Subsequent study visits will occur on post-injection day 7 and months 2, 6, 12, and 24. Safety of intra-articular injection of MSCs will be evaluated at study visits by interval history, physical examination and assessment of any adverse events that are observed/reported. Additionally, efficacy will be evaluated by having patients complete functional outcome measures including: Visual Analog Score (VAS) for pain, Knee Injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee (IKDC) Subjective Knee Form, and Lysholm Knee Scale. These will be completed at the pre-treatment visit and then repeated at the 2, 6, 12, and 24-month follow-up visits. Lastly, T1 rho and T2 mapping on magnetic resonance imaging (MRI) will be used to assess for improved cartilage quality after intra-articular injection of MSCs. An MRI will be obtained at the pre-treatment visit. At the 12 and 24 month follow up visit, additional MRIs will be obtained and analyzed to compare the pre-treatment MRI to post-treatment MRIs.
Evaluation of Safety, Tolerability, and Efficacy of XT-150, a plasmid DNA with a variant of human IL-10 transgene. XT-150 will be a single injection into the knee synovial capsule for the Treatment of Osteoarthritic Pain.
The hypothesis of this study is that since osteoarthritis of the knee is primarily a bone disease where the joint changes are secondary, and bone growth stimulators function to decrease intraosseous venous congestion and remodel bone, then there is a potential benefit for the treatment of osteoarthritis of the knee with bone growth stimulators.
Rehabilitation after total knee arthroplasty is very important in terms of range of motion of the knee, muscle power, normal gait, pain control and consequently the patient's satisfaction. Convectional rehabilitation methods in assist of therapist required high demand of resources. Recently, outpatient clinic or tele-communication tool based rehabilitations were investigated and reported equivalent results. However, those methods also required group or one-to-one facing that restricted availability of the exercise. With development of the motion tracking technology, new device that gives real time feedback with augmented reality images can be used for rehabilitation in home-based setting. This study aims to compare the clinical outcomes after the rehabilitation by interactive home-based device or conventional inpatient setting.
In this longitudinal prospective cohort study including young people with anterior cruciate ligament reconstruction (ACLR), the aims are to 1) study the association between different measures of muscle function and early future of knee osteoarthritis (OA) assessed as patient-reported pain, 2) explore potential associations between muscle function and features indicative of early radiographic OA measured with MRI, and early detection of OA in biomarker profiles, respectively, 3) monitor the patients' functional status, and early OA development over time and 4) investigate the prevalence of early knee OA in individuals 1 and 3 years post ACLR, respectively, compared to non-injured controls.The main hypothesis is that knee extensor weakness predicts future symptomatic OA of the knee (KOOS pain).
This objective of this study is to determine whether the Air Barrier System device reduces airborne colony-forming units (e.g., bacteria) present at a surgery site during total knee arthroplasty surgeries.
A clinical study to measure the effects of injection-site cooling on pain experienced after knee injections of capsaicin in healthy subjects and in patients with knee osteoarthritis.
Although knee pain is prevalent among community-dwelling older adults, little is known about how people in general handle their pain. We will conduct a survey to explore how knee pain affects people's lives and which treatments or self-management strategies they have chosen (or are being offered), and how these interact concerning pain reduction and maintenance of function.
This study was planned to evaluate the effect of neuromuscular exercise program on physical activity, functionality and balance in patients with knee osteoarthritis aged 35-65 years.
Unicompartmental knee arthroplasty by unicompartmental prosthesis (PUC) is a treatment for isolated internal femoro-tibial osteoarthritis. This intervention is justified in cases of significant discomfort, failure of medical treatment and the absence of osteoarthritis in femoro tibial external and patellofemoral femoro compartments. It aims to replace the native internal femoral tibial articulation by a joint between two implants, without intervening on the other compartments. The functional results of PUC are superior and faster than those obtained with total knee arthroplasty (TKA). Its indications and its realization are on the other hand very demanding to allow an optimal functional result. Robotic-assisted surgery provides an excellent level of precision, which could allow better positioning of implants, compared to the use of a mechanical ancillary, according to the first published studies. The functional results and survival of these implants could also be improved. The internal PUC with mechanical ancillary is carried out for many years in the orthopedic surgery department of Croix Rousse. For 3 years this surgery is sometimes performed with robotic assistance. The investigators would like to prospectively evaluate the clinical and radiological impact of robotic-assisted surgery when performing a Journey unicompartmental prosthesis (Smith & Nephew). The assessment of alignment during walking seems to be a paramount parameter in the results of the PUC and has not so far been evaluated in this type of robotic-assisted surgery.
