Study Description
Brief Summary
The goal of this observational registry study is to collect data related to patient reported outcomes (pain, function, quality of life, toxicity) in osteoarthritis (OA) patients receiving standard of care radiation therapy (RT).

Detailed Description
This is a single-institution, single-arm, prospective, observational study of patients with osteoarthritis who are being treated with standard of care radiation therapy (RT). The purpose of this non-interventional study is to systematically collect data related to patient reported outcomes (pain, function, quality of life, toxicity) with the goal of optimizing approaches to management with radiation therapy and clinical care during follow up. The primary endpoint of this study is a change in visual analog pain scale (VAPS) at 3 months post radiation and a variety of secondary endpoints are aimed at assessing disease control, patient function, avoidance of invasive surgery, and toxicity. Participants will complete patient-reported outcome surveys for pain and joint-specific functional assessment.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Patients with osteoarthritis receiving radiation treatment Patients with osteoarthritis receiving standard of care radiation treatment at UNC Radiation Oncology clinic. Radiation dose and fractionation prescription is at the physician's discretion. Typically, this prescription is delivered in 6 fractions, every other day, over 2 weeks. |
Outcome Measures
Primary Outcome Measures
- Change in Visual Analog Pain Scale (VAPS) Score from Baseline to M3 Post Radiation Treatment Completion [Baseline and 3 months post RT]
The investigators will use the visual analog 0-10 pain scale (VAPS) and compare the baseline pre-radiation measurement to that measured at 3 months post radiation.
Secondary Outcome Measures
- Change in Visual Analog Pain Scale (VAPS) Score Over Time [Baseline up to 5 years post RT]
The investigators will use the visual analog 0-10 pain scale (VAPS), where 0 is no pain and 10 is the worst physical pain imaginable, and compare the baseline pre-radiation measurement to that assessed at 6 weeks, 6 and 12 months, and yearly up to 5 years post radiation (RT). Higher scores indicate a worse outcome.
- Change in Hip Joint-Specific Outcome Over Time [Baseline up to 5 years post RT]
Joint-specific outcomes measures scales will include the Hip Injury and Osteoarthritis Outcome Score (HOOS). With 1 being the most functional usage of the joint, and 5 being least functional usage of the joint. The higher the value, the less functional outcome of the joint. Investigators will compare the baseline pre-radiation measurement to that assessed at 6 weeks, 3, 6 and 12 months, and yearly up to 5 years post radiation.
- Change in Knee Joint-Specific Outcome Over Time [Baseline up to 5 years post RT]
Joint-specific outcomes measures scales will include the Knee Injury and Osteoarthritis Outcome Score (KOOS). With 1 being the most functional usage of the joint, and 5 being least functional usage of the joint. The higher the value, the less functional outcome of the joint. It will compare the baseline pre-radiation measurement to that assessed at 6 weeks, 3, 6 and 12 months, and yearly up to 5 years post radiation.
- Change in Arm, Shoulder and Hand Joint-Specific Outcome Over Time [Baseline up to 5 years post RT]
Joint-specific outcomes measures scales will include the Disability of Arm Shoulder and Hand (DASH). With 1 being the most functional usage of the joint, and 5 being least functional usage of the joint. The higher the value, the less functional outcome of the joint. It will compare the baseline pre-radiation measurement to that assessed at 6 weeks, 3, 6 and 12 months, and yearly up to 5 years post radiation.
- Change in Foot Joint-Specific Outcome Over Time [Baseline up to 5 years post RT]
Joint-specific outcomes measures scales will include the Foot & Ankle Disability Index Score (FADI). With 1 being the most functional usage of the joint, and 5 being least functional usage of the joint. The higher the value, the less functional outcome of the joint. It will compare the baseline pre-radiation measurement to that assessed at 6 weeks, 3, 6 and 12 months, and yearly up to 5 years post radiation.
- Change in NSAID Dosage [Baseline up to 5 years post RT]
The investigator will compare NSAID doses at baseline to that measured at 6 weeks, 3, 6, and 12 months, and yearly up to 5 years post-radiation.
- Change in Opioid Dosage [Baseline up to 5 years post RT]
The investigator will compare opioid doses at baseline to that measured at 6 weeks, 3, 6, and 12 months, and yearly up to 5 years post-radiation.
- Change in NSAID Frequency [Baseline up to 5 years post RT]
The investigator will compare NSAID frequencies at baseline to that measured at 6 weeks, 3, 6, and 12 months, and yearly up to 5 years post radiation.
- Change in Opioid Frequency [Baseline up to 5 years post RT]
The investigator will compare opioid frequencies at baseline to that measured at 6 weeks, 3, 6, and 12 months, and yearly up to 5 years post radiation.
- Invasive Procedures [Up to 5 years post RT]
The investigator will report invasive procedures to treat the radiated joint experienced by each subject for the treatment of OA.
Eligibility Criteria
Criteria
