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.
ABSTRACT
Objective To compare the curative effect of fixation of adolescent tibial intercondylar emi-nence fracture among suture anchor,hollow screw and wire. Methods Forty-six adolescent cases of the tibial intercondylar eminence fracture treated with surgical treatment were selected from January 2010 to June 2016 and divided into three groups refer to intra-operative fixation suture anchor group(Group A),hollow screw group (Group B)and wire group(Group C).Duration of treatment,total operation time,hospital stay and surgery times were recorded. All patient condition was assessed with the Lysholm,Tegner,IKDC and VAS score. Results All patients received an average of 13(11~14)months follow-up visit. No blood-vessel,nerve and osteoepiphysis injured,infection and fracture displacement occurred.Before receiving treatment,difference in Lysholm,Tegner, IKDC and VAS score of group A,B and C showed no statistical difference.When it comes to hospitalization condi-tion,data were as follows.Group A/B/C:operation time(80.67 ± 16.68/114.00 ± 20.28/111.88 ± 20.07)min, hospital stay(8.40 ± 1.12/ 15.47 ± 1.25/ 15.19 ± 1.17)d,surgery times(1/2/2)times. Moreover,compared with those before operation and after operation in both of groups,the Lysholm,Tegner,IKDC and VAS score were improved(P < 0.05). Besides,the Lysholm,Tegner,IKDC and VAS score of group A,B and C did not have statistically significant difference yet after post treatment(P>0.05).Conclusions The curative effect of fixation of adolescent tibial intercondylar eminence fracture among suture anchor,hollow screw and wire was similar. By contrast,the fixation of fracture by use of suture anchor can decrease operation time and hospital stay to some extent. It had advantage of need not to have a second operation to remove the internal fixation and can be used in preference.
ABSTRACT
Objective To investigate gender differences in the curative effects of allograft and autologous hamstring tendon in anterior cruciate ligament reconstruction. Methods One hundred and forty-eight patients with the anterior cruciate ligament injury received surgical treatment were enrolled from January 2011 to January 2015 and divided into two groups,including group M(Men)and group W(Women). Patients in each group were also divided in the allograft group (Group A) and the autologous hamstring tendon group (Group B). The patient condition was separately assessed with the Lysholm,Tegner,VAS score and the value of KT-1000 before and after surgery. Results All patients received an average of 16(13-18)-month follow-up visit. No severe complication , such as blood-vessel and nerve injury ,infection and rupture of graft ,occurred in patients after operations. Compared with those before operation,the Lysholm,Tegner,VAS score and the value of KT-1000 after operation in four groups were significantly improved (P 0.05). Conclusions The curative effect of ACL reconstruction between allograft ligament and autologous hamstring tendon has no significant difference in gender. The selection of graft should be considered in more aspects.
ABSTRACT
Objective To compare and analyze the curative effects of mediopatellar plica syndrome under different therapies. Methods 147 patients with mediopatellar plica syndrome were enrolled in the study from January 2011 to January 2015 and divided into three groups refer to treatment: Group A, B and C. Each group was also divided in the youth group and the mid-age group. Different treatments were used in the three groups. Group A: drug therapy and physicotherapeutics; Group B: intraarticular injection regularly; Group C: arthroscopic surgical treatment. All patient conditions were assessed with Lysholm score. Results All patients received an average of 11 (9 ~ 13) months follow-up. No blood-vessel and nerve injured and infection occurred. Before receiving treatment, difference in Lysholm score of the three groups showed no statistical difference (F = 0.08, P = 0.926); after treatment, difference revealed significant difference (F = 15.48, P = 0.001). Compared with those before operation and after operation among the three groups, the Lysholm score was improved (tA = 3.43, tB = 6.74, tC = 7.99, P = 0.001). In the rangeability of Lysholm score, the Group C > B > A (F = 66.43, tAB = 5.97, tAC = 11.52, tBC = 5.55, P = 0.001);The general youth group > the general mid-age (t = 7.91, P = 0.001). Conclusion The best therapeutic method for mediopatellar plica syndrome is the arthroscopy. As for mid-age patients, it is necessary to inform them of possibility that prognosis is not well in preoperative planning.
