Intraarticular findings after gunshot wounds through the knee.
OBJECTIVE
To compare the radiographic findings in patients with a low-velocity gunshot wound through the knee with the intraarticular pathology as documented by arthroscopy, and to evaluate arthroscopic management of these injuries.


METHODS
Retrospective review of a protocol.


METHODS
Thirty-three patients with low-velocity gunshot wounds through the knee, no significant soft tissue injury, and no fracture requiring repair were studied. Radiographs were evaluated for bullet fragments, loose bodies, and debris. All patients were treated with arthroscopic evaluation and management of intraarticular pathology. The arthroscopic findings were compared with the radiographic findings.


RESULTS
Five chondral injuries and fourteen meniscal injuries not suspected on the basis of plain films were found during arthroscopic evaluation. Seven patients had no radiographic evidence of debris, loose bodies, or bullet or bone fragments in the joint. Five of these seven (71%) had debris and meniscal damage. Debridement of all loose bodies was possible using arthroscopy and occasional miniarthrotomy. No patient in the series had an infection.


CONCLUSIONS
Patients who sustain a low-velocity gunshot through the knee have soft tissue injuries not visible on plain radiographs in most cases, and therefore operative treatment is warranted. Arthroscopic management of these injuries appears to be a safe and effective method of treatment.
