title: [Bandi tibial tubercule osteotomy vs. artrhroscopy lavage in patelo femoral arthritis. 1 year follow-up].
abstract: BACKGROUND
  Osteoarthritis is a degenerative joint disease that modifies the mechanical and biological properties of articular cartilage and subchondral bone, treatment is aimed at relieving pain, maintain joint and reduce disease progression function. The aim of this paper is to compare the surgical outcomes of the arthroscopic articular cleaning and Bandi procedure by using the WOMAC scale.
  
  
  METHODS
  Cross-sectional study, functional outcome of treatment of patellofemoral ostheoarthritis by arthroscopic articular cleaning and Bandi procedure are compared. Variables were gender, age, affected side, surgical technique and preoperative and 12 months follow up WOMAC evaluation. We used descriptive statistics and t-test for mean difference in WOMAC between both groups of patients.
  
  
  RESULTS
  n = 37 patients, the mean age was 53.48 (28-82), ± 12.55 years; 11 (29.7%) males and 26 (70.3%) women, the affected side: 19 (51.35%) right and 18 (48.65%) left.
  
  
  METHODS
  45.9% arthroscopic articular cleaning and 54.1% Bandi procedure. Patients operated by both technics: Bandi and arthroscopic articular cleaning had improvement in pain, stiffness and physical function (p = 0.00); comparison of global WOMAC score for both techniques a year after showed no statistically significant differences (p = 0.78).
  
  
  CONCLUSIONS
  Both techniques (Bandi and arthroscopic articular cleaning) offer good results at 365 days of surgery, however patients managed by arthroscopic articular cleaning have less pain compared with Bandi procedure.
