Brief summary: This is a non-inferiority study in which the investigators compare two low-dose radiotherapy schemes, which are recommended from DEGRO Clinical Practice Guidelines (3 Gy vs 6 Gy) for the treatment of osteoarthritis and other osteodegenerative disorders.

A first randomization will be carried out among the patients included in the study:

* Patients in arm A will be treated at 3 Gy (0.5 Gy/fraction, 3 fractions/week), and patients in arm B will be treated at 6 Gy (1 Gy/fraction, 3 fractions/week).
* Patients should not know the arm to which they have been randomized.
* Once the treatment is finished, patients will be assessed at 8 weeks. If pain does not improve, a re-irradiation will be performed. If the patients were treated with 3 Gy a new randomization will be performed (3 vs 6 Gy again). If the patiens were treated with 6 Gy they will be re-irradiated with 6 Gy again.

The investigators will analyze the results obtained depending on the dose received and depending on the location of the treatment.

Detailed description: Painfull skeletal disorders are susceptible to be treated with low-dose radiotherapy. DEGRO guidelines recommend a dose between 3 and 6 Gy at 0'5 Gy/fraction or 1 Gy/fraction respectively. The investigators want to verify that both treatments (3 and 6 Gy) are similar to improve the pain and function in patiens with gonarthrosis and coxarthrosis, and there are no differences between both treatments, therefore, 3 Gy is not less than 6 Gy.

In this context, a prospective multicenter study is proposed. The study will include 338 patients to assess the efficacy of low dose irradiation (3 vs 6 Gy) in gonarthrosis and coxarthrosis.

Eligibility criteria: Inclusion Criteria:

* Age \>50 years
* Gonarthrosis or/and Coxarthrosis diagnose
* At least 1 year of evolution
* Non response to drug or surgery treatments
* Risk of colateral side effects due to the comorbidity of the patient with conventional treatments.

Exclusion Criteria:

* Previous high dose radiotherapy in the same location
* Conective tissue disease (LUPUS, reumathoid artritis, esclerodermia, Sd. Raynaud, Sd. Sjögren, polymiositis)
* Inherited Hipersesitivity Sindromes (ataxia-telangiectasia, Fanconi's anaemya, Sd. Nijmegen, Sd. Gorlyn, Sd. Cockayne, Sd. Down, Sd. Gardner, Sd. Usher)
* No follow up possibility
