Abstract:
Objective To study the performance of knee arthroscopy in patients with acute posteromedial corner injury and to explore the use of arthroscopy to help diagnosis. Methods From April to August 2017, the arthroscopic posteromedial corner after operation of 7 cases of acute knee joint injury patients data were retrospectively studied, treatment are in the same group. They were two man and three women, 37 ~ 59 years of old (average 49.6 years). All patients were selected for preoperative MRI to indicate medial collateral ligament damage. The VAS score was evaluated preoperative. When check-up knee flexion and 30° valgus stress test positive and 0° valgus stress test positive. Intraoperative arthroscopy was performed to confirm the injury of the Posteromedial corner. The medial meniscus was formed or stitched. The medial collateral ligament and Posteromedial corner were repaired. The knee X-ray examination were measured preoperative and in 2 months after surgery, Evaluation of the knee VAS score in 2 months after surgery. Results All patients were followed up for 2 months. The medial meniscus were easily observed and raise easily 5 cases undergoing arthroscopic surgery. All 7 patiens were showed the injury of the joint capsule ligament complex. All of the 7 cases showed the injury of the joint capsule ligament complex. Preoperative and postoperative knee medial clearance for 2 months in knee valgus stress buckling 30° [(9.2 ± 1.3) vs (3.0 ± 1.0) mm]. Preoperative and postoperative knee medial clearance for 2 months in knee valgus stress 0° [(8.8 ± 1.1) vs (2.9 ± 1.0) mm]. There were statistically significant differences (P < 0.05). After 2 months in knee valgus stress buckling is compared with the normal control group 30° [(3.0 ± 1.0) vs (2.9 ± 1.2) mm]. After 2 months in 0° knee valgus stress compared with normal control group [(2.9 ± 1.0) vs (2.8 ± 1.2) mm]. There was no statistical difference (P > 0.05). Preoperative and postoperative knee joint pain VAS score [(5.4 ± 0.3) vs (2.3 ± 1.1)]. There were statistically significant differences (P < 0.05). Conclusion Under arthroscopy detection in patients with acute Posteromedial corner injury. If it is easy to observe posterior horn of medial meniscus and the medial meniscus angle is easy to raise; The medial meniscus posterior horn joint capsule and ligament damage. They were indicated acute Posteromedial corner injury. Timely deal with medial meniscus and repair Posteromedial corner, the stability of the knee joint can be satisfactory.
