Brief summary
The Null Hypothesis is that there is no significant change in range of motion (ROM), pain, or function for a group of patients following total knee arthroplasty (TKA) who use the LRU pillow as compared to a control group of total knee arthroplasty patients who do not use the pillow.
Detailed description
1. Study design will be a Pretest-Posttest Control Group Design . Enrollment would be random assignment of 20 patients to a control group vs 20 patients to a treatment group for patients with the diagnosis of osteoarthritis (OA) of the knee admitted for primary total knee arthroplasty. For specifics of patient assignment, please see below under Recruitment Procedures. 2. Unpaired t-Tests will be used to determine differences between mean scores for the dependent variables (pain, range of motion, functional mobility). Analysis of Covariance will be run to quantify the effect of the co-variates of age, gender, body mass index (BMI), and contralateral previous TKA. Confidence Intervals will be set at 95%.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Range of Motion | 3 Days | Knee ROM measured both actively and passively with a standard long arm goniometer twice daily for both groups. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pain | 3 Days | Pain will be assessed using a visual analogue scale twice daily both at rest and with activity (exercise). |
Other
| Measure | Time frame | Description |
|---|---|---|
| Function | 3 Days | Functional parameters of bed mobility, transfers, ambulation, gait, and stair climbing will be assessed daily using standard measures used in physical therapy assessment( dependent, moderate assist of one or two, minimal assist of one or two, hands on supervision, stand by supervision, or independence. ) |
