NCT01857505

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.

Outcome Measures

Primary Outcomes (2)

  • Length of Hospital Stay

    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.

    Retrospective review of hospital discharge records

  • Hospital cost

    Hospital cost analysis will be undertaken for each group.

    Retrospective review of utilization records

Secondary Outcomes (2)

  • Post Operative Pain Medication Utilization

    After retrospective chart review is complete -- approximately 6 months

  • Utilization of inpatient physical therapy resources

    Retrospective review -- of hospital discharge

Study Arms (2)

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

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.

Sampling MethodProbability Sample
Study Population

Patients who have undergone primary uncemented hip replacement at our institution (Anne Arundel Medical Center) through either a posterior approach or direct anterior approach on a fracture table utilizing the identical post operative protocol.

You may qualify if:

  • Consecutive single surgeon series of patients who have undergone primary uncemented hip replacement at our institution through either a posterior approach or direct anterior approach on a fracture table. Posterior approach patient - most recent patient prior to March, 2010, compared with consecutive recent anterior approach patients with minimum of 6 month follow-up.
  • Diagnosis of osteoarthritis, inflammatory arthritis, or avascular necrosis.
  • No previous surgery on affected hip.
  • Age 40-90 at time of surgery

You may not qualify if:

  • Patient not permitted to bear full weight after the procedure, per post operative instructions
  • Hip replacement performed for acute fracture.
  • Previous hip surgery.
