Abstract: | We report a case of subcutaneous pretibial ganglion, with direct communication to the tibial tunnel after an autologous reconstruction
of the anterior cruciate ligament with hamstring tendons. The tibial graft fixation was with a 9 mm poly-L-lactide interference
screw 5 years earlier. The screw had undergone complete resorption at the time the cyst occurred. No joint inflammatory reaction
or graft insufficiency was detected. The patient underwent cyst excision and curettage of the tibial tunnel with full recovery.
This complication seems to be the consequence of a direct communication between the joint and the pretibial subcutaneous tissue
through a fibrous tibial tunnel and would have occurred, as there is no full osteointegration of the graft due to the resorption
of the bioabsorbable interference screw. |
