The purpose of this study is to describe the chronology of post operative pain in patients undergoing total knee arthroplasty and total hip arthroplasty. Further, within this population the predictive validity of the Defense and Veterans Pain Rating Scale will be assessed for persistent post surgical pain.

This is a prospective descriptive correlational design looking to characterize postoperative pain variables across various procedures that historically have significant levels of persistent post-surgical pain. Further, bivariate correlations at different time points will be examined to see how DVPRS along with Pain Assessment Screening Tool and Outcomes Registry (PASTOR) correlates with other measures.

Methodology/Technical Approach A total goal of 250 participants will be queried regarding their postoperative pain experience following shoulder arthroscopy and knee arthroscopy. Descriptive multidimensional tools (the DVPRS and the electronic Pain Assessment Screening Tool and Outcomes Registry (PASTOR)) will be used preoperative either during their preoperative surgical visit or the day of surgery and extending to 6 months postoperatively. As these tools have been utilized in previous studies for the prediction of persistent post surgical pain, the DVPRS will additionally be evaluated for its predictive validity as it is a short, easy-to-administer, bedside tool.

Inclusion Criteria:

1. Patients undergoing the following surgeries: Total Knee Arthroscopy, Total Hip Arthroscopy.
2. DEERS eligible

Exclusion Criteria:

1. Younger than 18
2. Refuses participation
3. Cannot understand English
4. Has cognitive deficiencies
5. Ambulatory surgical status where they go home same day.

1. Male and female military health care beneficiaries age 18 years and older presenting any of the following surgeries: total knee arthroplasty and total hip arthroplasty.
2. The recruitment and participation in this study will have minimal impact on surrounding health care activities. This study is measuring pain in a more specific manner than usual to describe the perioperative pain experience and evaluate the predictive capability of the DVPRS. Measurements in this study will not be used to make therapeutic decisions. Participants will be screened from the Surgical Scheduling System (S3) and joint arthroplasty surgeon's scheduling nurse prior to surgery and approached upon their preoperative visit with their surgeon.
