Brief Summary
Rationale of the study is to evaluate through a prospective randomized controlled study if a modified direct superior posterolateral approach (sperimental approach) to the hip articulation which entirely spares i.e. avoids the sacrifice of the fascia lata might elicit a better outcome in terms of gait, balance, strengths recovery, clinical performance, patient reported outcome measurement (Short Form-12(SF-12); Hip disability and Osteoarthritis Outcome Score (HOOS)) and overall recovery time in patients undergoing TotalHipArthroplasty with the aid of dedicated, modified instrumentation in order to properly access this modified route. The investigators expect an improvement on selected gait analysis parameters in sperimental approach in order of 2% of range of motion (ROM) recorded 1 month after surgery. Based on this assumption sample size calculation will be conducted.

Outcome Measures
Primary Outcomes (3)
evaluate spatiotemporal variables in meters among two different access routes, one a traditional posterolateral mini approach and the other a modified posterolateral superior approach fascia lata sparing
spatiotemporal variables: step length (meters), stride length (meters).
Change from Baseline spatiotemporal variables in meters at 3 months
evaluate spatiotemporal variables in percentage among two different access routes, one a traditional posterolateral mini approach and the other a modified posterolateral superior approach fascia lata sparing
Spatiotemporal variables: stance phase (percentage), swing phase (percentage)
Change from Baseline spatiotemporal variables in percentage at 3 months
evaluate kinematic parameters in degrees among two different access routes, one a traditional posterolateral mini approach and the other a modified posterolateral superior approach fascia lata sparing
Kinematic parameters (in degrees): hip flexion-extension ROM, hip abduction-adduction ROM, Hip rotation ROM, Hip Obliquity ROM.
Change from Baseline Kinematic parameters in degrees at 3 months
Secondary Outcomes (1)
evaluation of instability with BEStest
Change from Baseline BESTest at 3 months
Study Arms (2)

ACTIVE COMPARATORposterolateral approach 25 patients
Interventions
GROUP II :Patients positioned in lateral decubitus.landmark for incision is the apex of the greater trochanter,and skin, subcutaneous tissue except fascia are incised accordingly. Fibers of gluteus will be separated and not incised.posterior capsulotomy is performed,;femur is dislocated and neck osteotomy carried out, followed by preparation of femoral canal with progressive broach. Acetabulum is prepared with burs of increasing diameter, and acetabular cup is impacted. A polyethylene insert and a femoral rasp are subsequently introduced.All remaining definitive implants can be positioned.

Eligibility Criteria
You may qualify if:
- Non-inflammatory degenerative joint disease, including osteoarthritis
- Patients in the age from 60 to 85 included
- Consenting to actively participate in the study and in the rehabilitation follow up program as foreseen by the study
- ≤ Body Mass Index (BMI) ≥ 30 kg/m2
- patient without contralateral THA
You may not qualify if:
- Active infection or suspected latent infection in or about the hip joint
- Bone stock that is inadequate for support or fixation of the prosthesis
- skeletal immaturity
- any mental or neuromuscular disorder that would create an unacceptable risk of prosthesis instability, prosthesis fixation failure or complication in post-operative care
- Obesity (BMI ≥30kg/m2)
