Registry for Total Joint Surgery Outcomes

This study is an observational registry designed to track the experiences of patients undergoing total hip or total knee replacement surgery (Total Hip Arthroplasty or Total Knee Arthroplasty). Researchers will collect information before and after your surgery to understand how these procedures affect your comfort and ability to function over time. They will use standard questionnaires to measure your joint pain and satisfaction. You may be able to join if you are 18 or older, speak English, and are scheduled for total joint replacement surgery with the main doctor leading this study. The study aims to gather information for quality improvement and future research. Success will be measured by changes in scores like the Knee Society Score and Forgotten Joint Score over five years.

Study design
This is an observational study collecting information from 10,000 participants undergoing total joint replacement surgery. It is not testing a new treatment but rather observing outcomes of standard procedures.
What's involved
You would provide information before your surgery and at 6 weeks, 6 months, 1 year, 2 years, and 5 years after surgery. This includes completing questionnaires and potentially participating in gait analysis and physical capacity testing.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for up to 5 years after their surgery.

What this trial measures

  • Knee Society ScorePre-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 ScorePre-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 SurveyPre-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 ExpectationsPre-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 HealthPre-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 SurveyPre-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 HipPre-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.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.
