Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Direct Anterior Approach hip replacement

Single surgeon series of 105 consecutive patients who underwent hip replacement via the direct anterior approach on a fracture table

No interventions assigned to this group

Posterior Approach Hip Replacement

105 consecutive patients previously operated on by a less invasive posterior approach at the same institution. These surgeries occurred prior to March, 2010.

No interventions assigned to this group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

2. Diagnosis of osteoarthritis, inflammatory arthritis, or avascular necrosis.
3. No previous surgery on affected hip.
4. Age 40-90 at time of surgery

Exclusion Criteria

1. Patient not permitted to bear full weight after the procedure, per post operative instructions
2. Hip replacement performed for acute fracture.
