Hip Osteoarthritis

Total Hip replacement, Fracture table, DePuySynthes, Direct anterior approach hip replacement, Posterior approach hip replacement
Brief summary
The investigators propose to evaluate and compare the percentage of patients who are able to be discharged in less than 3 days after undergoing total hip arthroscopy through either a direct anterior or posterior approach, utilizing the identical post operative protocol. The investigators also propose to evaluate the costs associated with the two different approaches to hip replacement in the same group of patients. Post operative resource utilization, discharge disposition, and pain medicine requirement will also be evaluated.
Detailed description
The investigators hypothesize that a higher proportion of patients treated with the direct anterior approach for hip replacement will be able to leave the hospital in less than 3 days when compared with a less invasive posterior approach. Secondly, decreased length of stay associated with the procedure may reduce hospital costs.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Length of Hospital Stay | Retrospective review of hospital discharge records | The length of stay and proportion of patients who went home in less than 3 days will be determined for each group. To evaluate and compare the percentage of patients who are able to be discharged in less than 3 days after undergoing total hip arthroscopy through either a direct anterior or posterior approach, utilizing the identical post operative protocol. |
| Hospital cost | Retrospective review of utilization records | Hospital cost analysis will be undertaken for each group. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Post Operative Pain Medication Utilization | After retrospective chart review is complete -- approximately 6 months | Analysis of post operative pain medicine requirement will be compared for the two groups. |
| Utilization of inpatient physical therapy resources | Retrospective review -- of hospital discharge | Utilization of inpatient physical therapy resources and post hospital discharge disposition will be compared for the two groups. |
