Objective to investigate the effect of arthroscopic treatment of femoral intercondylar fossa. Methods under the microscope, the expansion of the intercondylar fossa. Results 37 knees were followed up for a period of 6 to 12 months. The average preoperative Lysholm score was 59 points (range from 41 to 75), with an average of 85 points (range from 70 to 95) after operation, and the impact was disappeared and the joint function was improved significantly (P), with progressive knee extension and flexion. Physical examination: mild flexion deformity of the knee, the extension was limited to 10 degrees to 20 degrees, and the knee hyperextension test was positive. X-ray and MRI showed the knee joint space narrowing, intercondylar fossa osteophytes in 27 knees, tibial intercondylar eminence osteophytes in 17 knees, intercondylar fossa synovial hypertrophy in 10 knees, 4 knees loose body.
1.2 methods of treatment using a standard arthroscopic patellar before the inside and outside of the entrance, in order to check every compartment of knee joint. Microscopically, the intercondylar fossa of tibial intercondylar eminence osteophyma; part of the fiber ACL beam fracture and wear a horsetail. For localized treatment on the degeneration of cartilage, menisci rupture and thickening of synovial tissue, removal of loose bodies; the knee flexion 90 degrees, from inside and outside the entrance into the anterior surgical instruments of femoral intercondylar fossa stenosis were expanded forming, focusing on the top and lateral wall cleaning: resection of femoral intercondylar fossa anterior lateral wall 3 ~ 5mm, widening the intercondylar fossa; intercondylar fossa with small curved lateral 1/2 or 2/3 before the top chisel by former back oblique shaped partial resection of bone, deepen the top 5 ~ 10mm, and the longitudinal axis of the femoral shaft bone tilt angle at least not less than 40 degrees, to expand the intercondylar fossa angle. With a narrow bone knife and drill the osteophyma excision extension of ACL and the smoothed intercondylar fossa of the anterolateral wall maintained 3 ~ 5mm distance, probe roughly determine the distance, knee extension and flexion without barrier, open intra-articular bone block has been eliminated. A large amount of physiological saline was used to flush out the debris.
1.3 observe the joint pain, function improvement and knee Lycholm score before and after operation.
1.4 statistical processing data were expressed as mean + standard deviation (+ S), SAS statistical software processing, using paired t test, P < 0.05 was statistically significant.
2 the results of 37 cases were followed up from 6 to 12 months, the joint pain disappeared or relieved obviously, and the joint function was improved obviously. Lycholm score of knee joint: the average score was 59 (range from 41 to 75), with an average of 85 points (range from 70 to 95) after operation, with an average increase of 26 points. There was a significant difference between the two groups (P
