Arthroscopic excision of the osteoid osteoma at the distal femur

Abstract

Osteoid osteoma is a benign, osteoblastic and painful tumoral lesion. Apart from en-bloc resection, intralesional resection and percutaneous excision or destruction of the nidus, arthroscopic removal of the lesion in intraarticular locations have been reported. We present a patient with osteoid osteoma at distal femur which is accessible through knee joint, treated by arthroscopic complete excision.

Arthroscopic Excision of an Intraarticular Osteoid Osteoma in the Distal Femur

“…Gunes et al8) reported a case of arthroscopic excision of an intraarticular osteoid osteoma of the distal femur as in our case. In their report, arthroscopic findings were of a hyperemic area in the synovium and red-purple colored soft tissue after cortical bone lesion removal by arthroscopic curettage 8). In our case, synovial hyperemia was minimal and the slightly elevated lesion was found in the synovial area of the superior aspect of the lateral femoral condyle.…”

“…Complete arthroscopic excision of an osteoid osteoma located within the synovial cavity of the knee has been rarely reported 58). Gunes et al8) reported a case of arthroscopic excision of an intraarticular osteoid osteoma of the distal femur as in our case.…”

“…For this reason, most authors recommend avoiding the use of a motorized instrument prior to sampling 5810). We did not use any motorized instrument until adequate material was obtained.…”

“…However, if the tumor exhibits intraarticular involvement, the diagnosis can be more difficult and atypical clinical and radiologic features may lead to a delayed diagnosis 23567). The treatment is aimed at nidus removal traditionally by en-bloc resection, by curettage, or by various other methods 148). Intraarticular osteoid osteomas are rare and although they may be encountered in any joint, the hip, elbow, and talus are most vulnerable 39).…”

Navigation Endoscopic Assisted Tumor (NEAT) surgery for benign bone tumors of the extremities

“…Arthroscopic assisted excision of benign bone tumors has been reported, but only for intra-articular lesions [1][2][3]. This method requires intraoperative 2D fluoroscopic images for accurate localization of the tumor and positioning of the instruments.…”
