Mid-long term efficacy of osteo-periosteal turned over orthotopically for chondromalacia patellae / 中华骨科杂志

ABSTRACT

ObjectiveTo investigate the method of osteo-periosteal turned over orthotopically for treating chondromalacia patellae disease and observe the mid-long term efficacy postoperatively.Methods From April 1996 to June 2000,21 patients with chondromalacia patellae were treated in our hospital.Amone them,13 cases were performed osteo-periosteal turned over orthotopically,including 3 males,10 females; with the mean age of 59 years(range,47-65 years).HSS and Lysholm knee rating scale were employed to analysis the results.ResultsThe patients were followed up from 114 to 162 months(mean,133.2 months).One of the patients lost follow-up due to death.Before operation the HSS knee score was 20-58 (34.2±3.8),and 1 year,3 year,5 year,7 year,and 9 year after operation the HSS knee score were 55-70(60.0±7.0),55-82 (64.1±5.9),60-90 (70.1±3.2),50-85 (63.1±4.1),and 50-75 (57.3±2.9) respectively.And Lysholm knee rating scale also showed similar results.The chondromalacia patellae patients before and after operation were significant different.Bone periosteum transplant tissue and surrounding defective tissue healed perfectly,functions recovered perfectly.ConclusionThe method of osteo-periosteal turned over orthotopically has the capabilities to form cartilage.The therapeutic effect and facies articularis patellar is satisfactory.But it only can restore articular cartilage of patellar and does not help for genual malformation.
