Reconstruction of the knee extensor mechanism after wide excision of intramuscular hemangiomas affecting the quadriceps femoris muscles

ABSTRACT

The wide excision of intramuscular hemangioma, which affects the quadriceps femoris muscle, usually is followed by inefficient knee extension, and patellar instability. The surgeons with this problem in their minds sub-totally excised it, and this is usually followed by high recurrence rate. Five patients with large symptomatic intramuscular hemangioma affecting the quadriceps femoris muscles, constitute the material of this study from September 1996 to June 2001; in 2 of them the hemagioma were previously incompletely excised and recurred. Three patients were males and two were females. Their ages ranged from 6 to 24 with average 12.4 years. The right side was affected in 3 patients, while the left in 2 patients. The vastus medialis was affected in 3 patients and the lateralis in 2 patients. Wide excision with reconstruction of the extensor mechanism was done for every patient. The shortest follow up period was 3 years, and the longest was 8 years. The results obtained were excellent in all patients [100%], no good or poor cases [zero%]
