To determine if education about pain given prior to Knee Arthroplasty will result in better outcomes following surgery
To determine if a preoperative pain neuroscience education (PNE) program would result in superior outcomes compared to usual preoperative education for total knee arthroplasty (TKA). Patients will receive traditional hospital preoperative TKA program (usual care group) or receive the same program plus an additional 30-minute PNE program (experimental group). Pre and post measurements at 1, 3 and 6 months for pain, function, fear of movement and pain catastrophization. We will also compare opioid usage, healthcare expenses and patient satisfaction between groups.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Usual education control group (CG) | Active Comparator | The CG received the traditional hospital preoperative program, which was consistent with current preoperative TKA protocols. The CG received education covering anatomy of the knee joint, information about the joint replacement surgery, what to expect when they were admitted for surgery, what to expect immediately after surgery, pain medications, postoperative rehabilitation/physical therapy, etc. The CG received a hospital-based booklet with this information. |
|
| Experimental group (EG) | Experimental | The EG underwent an additional 30-minute group PNE program, followed by the usual preoperative education program from the hospital. The PNE program used in this TKA study was an adaptation of the PNE program developed for LS. The educational program was designed to be delivered by a physical therapist in a group session to patients prior to their TKA. |
