A Prospective Total Joint Surgery Registry to Monitor Short- and Long-Term Clinical Outcomes
What this study is about
The investigators propose a forward-looking longitudinal registry study to collect and compare preoperative and postoperative information from patients who undergo total joint arthroplasty (TJA). Outcomes will be assessed with common, routinely available patient-reported outcomes measures (PROM's) such as the HOOS Jr.
View original scientific description
The investigators propose a prospective longitudinal registry study to collect and compare preoperative and postoperative information from patients who undergo total joint arthroplasty (TJA). Outcomes will be assessed with common, routinely available patient-reported outcomes measures (PROM's) such as the HOOS Jr., Oxford score, Knee Society Score, Harris Hip Score, and other patient satisfaction and function assessments in use in Orthopedics.

Primary outcome measures
Knee Society Score
Time frame: Pre-op, 6 weeks, 6 months, 1 year, 2 years, and 5 years
The Knee Society Score (KSS) provides a 0 to 100 score measuring function, pain, and range of motion in the knee before and after surgery. A score of 0 indicates the worst outcome, while a score of 100 indicates the best outcome.
Forgotten Joint Score
Time frame: Pre-op, 6 weeks, 6 months, 1 year, 2 years, and 5 years
The Forgotten Joint Score assesses how aware the patient is of their joint in everyday life. A score of 0 is the worst (always aware) while a score of 100 is the best (the patient is so comfortable, they forget that the joint was replaced).
Joint Awareness Survey
Time frame: Pre-op, 6 weeks, 6 months, 1 year, 2 years, and 5 years
The Joint Awareness Survey is an abbreviated version of the Forgotten Joint Score. It also has 0 as the worst outcome and 100 as the best. We are including it to determine if it can reliably be used in place of the Forgotten Joint Score, which is longer and more burdensome for patients to fill out.
Pain Satisfaction Expectations
Time frame: Pre-op, 6 weeks, 6 months, 1 year, 2 years, and 5 years
This survey assesses patients' satisfaction with their joint, their pain level, their overall function, and their need for pain medication. 0 is the worst score while 100 is the best.
PROMIS Global Health
Time frame: Pre-op, 6 weeks, 6 months, 1 year, 2 years, and 5 years
This survey assesses the general health and quality of life of the patient. It is also a 0-100 point scale with 100 being best, 0 being worst, and 50 being average. Every 10 points represents one standard deviation from the mean.
Koos Jr. Knee Survey
Time frame: Pre-op, 6 weeks, 6 months, 1 year, 2 years, and 5 years
This survey assesses stiffness, pain, and function of the knee. 0 is the worst score and 100 is the best.
Harris Hip
Time frame: Pre-op, 6 weeks, 6 months, 1 year, 2 years, and 5 years
This survey assesses pain, deformity, and range of motion of the hip. A score of 0 indicates the worst outcome and 100 indicates the best.
Hoos Jr.
Time frame: Pre-op, 6 weeks, 6 months, 1 year, 2 years, and 5 years
This survey assesses pain and function of the hip in daily life. A score of 0 indicates the worst outcome, while a score of 100 indicates the best.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
