The authors have performed arthroscopic management in 47 knees of 41 patients with one or more loose bodies in the from september, 1983 to May, 1995 at Guro hospital. The results wee analyzed from the base of correlations of the gross and
microscopic
pathology with the clinical history, roentgenogram and surgical fidings.
1. There were 23 males and 18 females and mean age at operation was 23.4 years(ranging from 8 years to 65 years0
2. The loose bodies were visible radiologically in 36 knees, but not visible in eleven
3. The causes of loose bodies in the knee presented that osteochondritis dissecans of the femoral condyle and patella in 15 knees, the osteochondral fracture. In 11, the meniscus in 5, synovial chondromatosis in 4, osteoarthritis in 5,
osteonecrosis in
2, foreign body in one and unidentified was in two.
4. The associated disease with loose bodies were meniscus injury in 11 knees, lateral discoid tear in 9, osteoarthritis in 8, patellar subluxaiton in 4, and PCL injury in one.
5. The loose bodies observed by arthroscopy were located at intercondylar notch in 11 knees, suprapatellar pouch in 10, anterolateral compartment in 8, posteromedial compartment in 7, anteromedial compartment in 3, medial gutter an under the
lateral
meniscus in meniscus in each 2 knees and multiple sites in 4.
6. In the 3 knees of osteochondritis dissecans, fixation of loose body was performed with absorbble K-wire and screw, but in most cases, loose bodies were removed.
7. We failed to remove loose bodies in 3 knees, which were located in the pjosteromedial compartment.
