Arms Assigned Interventions
Active Comparator: 1
The Copeland uncemented prostheses with titanium-sprayed, hydroxyapatite (HA)-coated bone-contact area used as a treatment for shoulder osteoarthritis
Procedure: Copeland or Global CAP resurfacing prosthesis
Both Copeland and Global Cap are uncemented prostheses with titanium-sprayed, hydroxyapatite (HA)-coated bone-contact surfaces.
Active Comparator: 2
The Global Cap uncemented prostheses with titanium-sprayed, hydroxyapatite (HA)-coated bone-contact area used as a treatment for shoulder osteoarthritis
Procedure: Copeland or Global CAP resurfacing prosthesis
Both Copeland and Global Cap are uncemented prostheses with titanium-sprayed, hydroxyapatite (HA)-coated bone-contact surfaces.

Detailed Description:

In this randomized study, we wish to investigate with the use of clinical and radiological parameters whether there is a difference between the result of treatment of shoulder osteoarthritis with the Copeland resurfacing prosthesis and the Global CAP resurfacing prosthesis.

Clinical parameters with the help of the Constant Shoulder Score (CSS) and Western Ontario Osteoarthritis of the Shoulder Index (WOOS):

  1. Pain
  2. Activities of Daily Living (ADL)
  3. Range of Motion (ROM)
  4. Muscle strength

Radiologic parameters:

  1. Migration of resurfacing prostheses with use of MB-RSA
  2. Bone density around the prosthesis measured with Dual Energy X-ray Absorptiometry (DEXA)
  3. Correlation between bone density and prosthesis migration

Criteria

Inclusion Criteria:

  2. Aged 18 years or older and fit
  3. Informed, written consent -

Exclusion Criteria:

  1. Patients found unsuitable preoperatively for a resurfacing prosthesis
  2. Patients aged 85 or older
  3. Patients with rheumatoid arthritis

  6. Patients requiring regular systemic steroid treatment
  7. Female patients taking hormone substitution
  8. Patients with metabolic bone disease
  9. Severe shoulder instability with large rotator cuff defect ( will often necessitate special prosthesis components or even major soft-tissue surgery)
