To approach the values of arthroscopic minimally invasive surgery (MIS) in diagnosis and treatment of benign bone and joint tumors.
20 cases of benign bone and joint tumors were diagnosed and treated by arthroscopic MIS. There were 9 males and 11 females in the group. Their average age was 26 years old (from 19 to 37). There diseased region: 9 in distal femurs, 6 in knee joints, 4 in calcaneus, 1 in distal tibia. Plain radiographies, MRI examinations and CT scans were performed with all patients preoperatively, among them 12 patients were inspected by ECT. In the treatments of distal femoral and calcaneal benign tumors, firstly, Kirschner wires were drilled into the pathological regions under the monitor of C-arm; then 6 mm diameter hollow drills were drilled follow the guide Kirschner wires and run-through the opposite side of cortical bone; then the arthroscope was inserted to check-up the pathological regions, then curettes or bite clamps were inserted from the opposite side to clean up tumor tissues; finally, 8 of the 13 were embedded with allograft gelsiccation bone, other 6 were embedded with carbonate hydroxyapatite cement. One case of distal tibia epidermoid cyst were removed under arthroscope and filled with allograft bone. 6 soft connective tissue tumors in knee articular cavities were removed under the monitor of arthroscope.
According to pathological reports, 6 were yellow pigments tumors in knee articular cavities, 4 were osteoid osteomas of femoral bones, 3 were osteofibrous dysplasias, 2 were nonossifying fibromas, 4 were bone cysts of calcaneuses, one was distal tibia epidermoid cyst. All patients were followed up with 7 months to 4.6 years (average 25 months). No recurrence occurred, and their joint functions were well.
It is an accurate, minimally invasive and easy to manipulate technology to treat benign bone and joint tumors with the monitor of arthroscope.
