A Study Comparing Ceramic-on-metal Articulation to Metal-on-metal Articulation in Cementless Primary...
OsteoarthritisThe aim of this study is to demonstrate the non-inferiority of the ceramic on metal articulation using M2a-38™ mm cup compared to the metal on metal articulation using the same cup.

RSA of the ATTUNE Knee System: RCT Comparing Traditional Vs Enhanced-Fixation Device Designs
Knee OsteoarthritisThe principal objective of this study is to compare migration patterns between the Attune and Attune S+ PS knee systems using model-based RSA over the first 2 post-operative years. Secondary objectives include; comparison of 2-year migration values against published thresholds for adequate short-term fixation, quantify changes in functional and health status of subjects following surgery and compare between study groups, and assess occurrences of complications following surgery.
Cutibacterium Dermal Colonization: Implications for Total Hip Arthroplasty
Degenerative OsteoarthritisThis study is being done to investigate the colonization rate(growth rate) of a particular type of low-virulence (does not typically cause infection) bacterium called Propionibacterium, more specifically P acnes, the same bacterium that is responsible for the majority of acne. Information affecting hip surgery is currently unknown.
Physical Activity Pathway for Patients With Osteoarthritis in Primary Care (OA-PCP) (R33)
OsteoarthritisThe purpose of this study is to test an osteoarthritis (OA) primary care Physical activity Care Pathway (OA-PCP), a scalable intervention that includes: 1) a practical process for physical inactivity screening in primary care, 2) a brief, tailored physical activity (PA) counseling intervention via telephone, 3) connection of patients with community programs and other resources to support PA, and 4) follow-up with patients to deliver additional appropriate counseling and referrals to PA resources. This program will be compared to another program that provides education on a variety of topics important to understanding osteoarthritis (OA) and its care.

Tai Chi for Knee OA Pain Management: a Mechanistic Study
Knee OsteoarthritisMind-body ExerciseThis study is to determine how 8-week Tai Chi intervention alters plasma endocannabinoid and its receptors in monocytes/marcrophages, plasma oxylipinds, plasma brain-derived neurotrophic factor, brain white matter connectivity/efficiency, and functional/clinical outcomes in women with knee OA.
Measuring Synovial Fluid Components
Knee OsteoarthritisParticipants with grade 3 and 4 knee osteoarthritis will recieve aspiration of synoivial fluid, and then receive either dextrose, hemaotopoietic stem cell, or platelet rich plasma, or no injection. The synovial fluid will be analyzed for changes in components.
Unicondylar Knee Arthroplasty Versus Total Knee Arthroplasty in Patients With Anteromedial Osteoarthritis...
OsteoarthritisThis study is a randomized controlled trial comparing total knee arthroplasty (TKA) to unicompartmental knee arthroplasty (UKA) in patients with no to moderate anteromedial knee osteoarthritis. TKA patients will receive the Zimmer Persona (Warsaw, IN) posterior cruciate retaining total knee arthroplasty, while UKA patients will receive the Biomet Oxford (Warsaw, IN) mobile bearing unicompartmental knee arthroplasty. Outcome measures will include Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and Oxford Knee Score (OKS) questionnaires, as well as biomechanics and EMG analysis from the investigating gait lab. The investigators hypothesize that post-operative UKA patients will display higher clinical scores using WOMAC and OKS questionnaires, and superior biomechanical analysis measures. The investigators further hypothesize that the biomechanics data will assist in the understanding of the outcome score differential both pre- and post-operatively in both groups, as well as between-groups. Total follow up period will be two years.
