ABSTRACT
Objective To analyze the curative effect of fossa intercondyloidea of micro-fracture and comminution of subcutaneous fat pad on meniscal tear healing under arthroscopy. Methods During the clinical operation, the samples of the micro-fracture and fat pad comminution were attracted to the outside of the joint. The source and properties of cells were identified based on preclinical medicine experiment in vitro. In clinical research, 75 cases of the simple meniscus injury were selected from January 2014 to January 2016 and divided into three groups refer to treatment Group A, B and C. Different treatments were used in the three groups. Group A - micro-fracture group; Group B - fat pad group; Group C - blank group. All patients' conditions were assessed with Lysholm, VAS score and adverse event (Swelling, anterior knee pain). Results In the preclinical medicine experiment, cells released by micro fracture were fibroblast-like cells which tend to grow more rapidly in vortex shape. Cells released by comminution of fat pad contained a small amount of impurities and necrotic cells and are mostly similar to fibroblast in long spindle shape. Besides, the Human MSC Analysis Kit was used to authenticate two cells which were considered to be as BMSCs and IPFPSCs. In clinical research, all patients received an average of 10 (8 ~ 11) months follow-up visit. No severe complication, such as blood-vessel and nerve injury, infection occurred after operations in the patients followed. Before receiving the treatment, difference in Lysholm, VAS score and general condition of joint of Group A and B, C showed no statistical difference (P > 0.05). Compared with those before operation and after operation in both of four groups, the Lysholm and VAS score were improved (P < 0.05). Besides, there had significantly difference between group A and C, B and C after post treatment in Lysholm and VAS score (P < 0.05), however, group A and B did not. Compared group A and C, the early prevalence of adverse event of group B was higher, but last follow-up show no difference between three groups. Conclusion Combined with basic experimental and clinical studies, our research suggest that micro-fracture and comminution of fat pad have good effect on the repair of meniscus injuries. Nevertheless, it should be concerned that early prevalence of increased swelling amd anterior knee pain of comminution of fat pad.
