Brief Summary
In this prospective, randomized study, investigators will look at the outcome of total hip arthroplasty through the anterior approach in regard to the surgical treatment of the anterior hip capsule. At this time, there are 2 different techniques: one is excising this capsule and the second one is cutting the capsule and repairing it at the end of the procedure. The investigators set out to determine whether incising or repairing the capsule will benefit the patients in terms of postoperative pain level, range of motion of the hip joint, joint stability, surgical time and blood loss. Both preserving and excising the joint capsule are accepted techniques in performing total hip arthroplasty. The Investigators hypothesize that capsulectomy may allow for reduction in operative time, provide superior surgical exposure, and increased range of motion after surgery. The influence on post operative pain and dislocation rate is unknown.

Outcome Measures
Primary Outcomes (5)
Range of Motion- Resisted Hip Flexion Strength
Measurement will be recorded taken with patient in the seated position with the hip flexed to 90 degrees. Strength will be measured when resistance is applied to the knee as the patient brings the leg up. The following scale will be used (each may be +/-, i.e. 5+): * 5 = NORMAL - the patient is able to actively move through the full available range of motion (ROM) against gravity and against maximal resistance * 4 = GOOD - the patient is able to actively move through the full available ROM against gravity and against moderate resistance * 3 = MODERATE - the patient is able to actively move through greater than one half the available ROM against gravity and against moderate resistance * 2 = POOR - the patient is unable to actively flex hip against gravity * 1 = BAD - the patient is unable to flex muscle properly
Follow Up Visit (Up to six months)
Change in Range of Motion - Maximum Hip Flexion
This angle will be measured with the patient in the supine position utilizing a goniometer (recorded in degrees). Patients will flex the hip by bringing their leg as close to their trunk as possible with their knee bent. The angle between the trunk and leg will be recorded
Screening Visit, Follow-up visit (Up to six months)
Change in Range of Motion - Maximum Hip Extension
This angle will be measured with the patient in the prone position utilizing a goniometer. The patient will raise the lower leg to the limit of extension. The angle between the leg and table is recorded.
Screening Visit, Follow Up Visit (Up to six months)
Change in Range of Motion - Evidence of Flexion Contraction (Thomas Test)
This angle will be measured with the patient lying in the supine position. Patient will bring opposite knee to the chest, while the other leg remains extended. The angle between the extended leg and the table is recorded.
Screening Visit, Follow Up Visit (Up to six months)
Change in Pain Score with Resisted Hip Flexion
Measured using the Pain Assessment scale (PAS) of 0-10 (0 being no pain; 10 being worst imaginable pain).
Screening Visit, Follow Up Visit (Up to six months)
