The authors did percutaneous, arthroscopic-assisted osteosynthesis of patellar fractures associated with skin abrasions and lacerations in 11 patients. Skin problems did not delay the operation and the rehabilitation. The average followup was 2.8 years. All fractures healed without complications and good results were obtained in all patients using the criteria of Levack et al. This technique avoids the problems of patellar fractures with skin abrasions and may be adapted to other fractures of the patella.
