ABSTRACT
Objective:To explore the efficacy of small incision open reduction and internal fixation and arthroscopic high strength non-absorbable suture in the treatment of tibial avulsion fracture of anterior cruciate ligament (ACL).Methods:The clinical data of 72 patients with ACL tibial avulsion fracture treated in Shantou Central Hospital from April 2018 to April 2020 were analyzed retrospectively. The patients were randomly divided into control group ( n=36) and experimental group ( n=36). The control group was treated with small incision open reduction and internal fixation and the experimental group was treated with high intensity non-absorbable suture under arthroscopy. The general data, surgical indexes and postoperative adverse reactions of the two groups were compared, and the knee joint function indexes of the two groups before and after treatment were compared and evaluated by random walking model. The counting data were expressed by percentage, the comparison between groups was expressed by chi-square test, the measurement data was expressed by mean ±standard deviation, the independent t-test was used for inter-group comparison, and the paired t-test was used for intra-group comparison. Results:There was no significant difference in general information, intraoperative blood loss, preoperative Lysholm score, IKDC score, Tegner score, knee mobility, and bilateral tibial displacement distance between the two groups of patients ( P>0.05). In the experimental group, the operation time, hospitalization time, the first postoperative time to move to the ground, bone healing time, and the total incidence of adverse reactions were (68.41±7.65) min, (11.93±3.24) d, (6.37±1.85) d, (23.65± 2.28) weeks, 2.78% (1/36), the control group were (55.37±8.62) min, (13.45±2.96) d, (8.16±2.08) d, (25.79±2.46) weeks, 22.22% (8/36), the difference between the two groups was statistically significant ( P<0.05). The Lysholm score, IKDC score, Tegner score, range of motion of the knee joint, and the difference of bilateral tibial displacement distance after treatment in the experimental group were (85.27±5.28) points, (85.43±1.74) points, and (6.65±1.41) points, respectively. (108.45±5.79)°, (1.12±0.65) mm, the control group was (79.73±4.69) points, (80.37±1.59) points, (5.72±1.31) points, (97.58±5.42)°, (2.24±0.72) mm, the difference between the two groups was statistically significant ( P<0.05). Random walking model evaluation the improvement of knee joint function in the experimental group was significantly better than that in the control group. Conclusion:Arthroscopic treatment of ACL tibial avulsion fracture with high-intensity non-absorbable suture can significantly improve the knee joint function of patients with rapid recovery and high safety, so it has a broad prospect of clinical application.
ABSTRACT
Objective To investigate the potential differences in efficacy of anterior and posterior cruciate ligaments(ACL &PCL)reconstruction by using arthroscopy between autologous tendon and tendon allograft.Methods A total of 144 patients with ACL or PCL fracture were assigned into two groups,namely anterior tibial muscle tendons allograft(n =82)and tendons autograft(n =63).The graft was fixed by using the Endobutton and Intrafix systems. The general information,drawer test,Lachman test,IKDC score,Lysholm score and Tegner score were compared between groups before and after surgery.The mean follow -up period was 16 months,ranged from 6 to 24 months. Results Both two groups received significant improvement after surgery and met the requirements of ligament reconstruction.However,those patients received autologous tendon had less complications,better knee stability.There were significant differences in Lachman score,ADT/PDT score,IKDC score[(83.43 ±4.37)points vs.(81.05 ± 4.41)points],Lysholm score [(90.59 ±3.43)points vs.(89.03 ±3.25 )points],and Tegner score [(7.79 ± 0.94)points vs.(7.37 ±0.90)points]between the two groups in 12 -month(χ2 =9.509,9.080,t =3.237,2.770, 2.729,all P <0.05).Conclusion The efficacy of autologous tendon is better than tendon allograft in anterior and posterior cruciate ligaments reconstruction,which should be considered has highest priority in treating patients with anterior or posterior cruciate ligaments fracture.
