| Objective:To investigate the clinical effect of arthroscopic anterior cruciate ligament(ACL)reconstruction and to measure the gait parameters before and after ACL reconstruction by using the foot space pose assessment and analysis system(Sennotech Insole X 1.0).The gait parameters of the population were compared and analyzed.The features of gait changes before and after ACL reconstruction were analyzed and evaluated.The gait data of ACL injury were improved to provide data reference for the gait analysis of ACL injury later,in order to better guide the ACL reconstruction.After the clinical rehabilitation.Methods:A total of 50 patients diagnosed with anterior cruciate ligament injury who were admitted to our department from January 2017 to August 2017 were selected as subjects and a total of 28 patients met the inclusion criteria.Arthroscopic anterior cruciate ligament autogenous semitendinosus and gracilis reconstruction was performed using a wearable foot space pose assessment system(Sennotech Insole X 1.0),and its plantar pressure before and 3 months after surgery was evaluated.Changes in phase and parameters were measured.The phase changes and parameters of the plantar pressure of 28 healthy people during the same period were used as blank controls.A prospective case-control analysis was performed.The experimental group consisted of 28 patients.The average time from initial injury to surgery was 1.8 months,including 21 males and 7 females.The average age was(30.21±6.82)years,the average height was(167.8±7.5)cm,and the average weight was 74.8.±10.2)kg.The inclusion criteria were: voluntarily participating in the trial after the patient had personally understood the purpose and related risks;unilateral primary ACL injury and no other injuries in the knee joint;no vascular nerve injury in the lower extremities;subjective signs of knee instability,but No obvious joint restriction,can perform general daily activities;no congenital knee joint malformations.Exclusion criteria: Professionally trained athletes,MRI showed that there were other injuries in the knee joint.The control group consisted of 28 patients,including 18 males and 10 females.The average age was(31.43±7.09)years,the average height was(166.9±8.1)m,and the average weight was(72.6±14.3)kg.All patients underwent preoperative and postoperative VAS scores,Lysholm scores and IKDC2000 scores,and statistical analysis was performed to evaluate the clinical effect after surgery.All the test subjects wore this measuring device and walked on the flat road for 60 s according to the autonomous walking speed.The gait parameters and changes in this phase were measured and analyzed.The gait parameters of the normal group were compared,analyzed and evaluated.The characteristics of gait changes before and after ACL reconstruction,improve the gait data of ACL injury,provide data reference for gait analysis of ACL injury,and provide further guidance for clinical postoperative rehabilitation.Results:All 28 subjects completed the test,and the follow-up rate was 100%.The results of quantitative evaluation of symptoms and signs showed that the excellent and good rate was 96.43%.Subjective results showed that the VAS score of the affected side was significantly improved from preoperative(7.04±1.20)points.After 3 months(1.00±0.90),the Lysholm score was significantly improved from(44.00±2.55)preoperatively to(92.71±3.00)3 months postoperatively,and the IKDC2000 score was preoperatively(45.07±).6.83)points improved to(86.61±3.08)points at 3 months after operation,but there was no significant difference between the VAS score,Lysholm score,and the IKDC2000 score before and after surgery for the contralateral side;the gait parameter score results showed that: After ACL injury,the preoperative ipsilateral stride length,step height,impact force,support phase,flat foot period,landing elevation angle,elevation angle and maximum swing speed parameters all decreased(62.21±5.56,15.86±1.84,0.35±0.074,47.02±1.72,10.15±1.45,38.83±1.58,11.55±1.66,45.15±1.6).All parameters were improved at 3 months after reconstruction(112.82±4.54,18.43±1.7,0.7±0.024),60.64±1.3,15.21±1.4,44.43±1.54,18.67±1.41,61.02±1.56,3.79±0.14),while the pre-extensive extension period and swing phase were increased(41.84±2.64,40.64±1.41),and the parameters decreased significantly after reconstruction(35.83±1.83,36.96±1.3).Although the average value of the parameters after 3 months of reconstruction compared with the normal values was slightly different,it was not statistically significant.Conclusion:1.Three months after ACL reconstruction,the ipsilateral knee pain was significantly improved and the function was well restored;2.Both ACL injury and reconstruction could affect the gait,and the preoperative pace and height The impact force,support phase,landing phase,flatfoot period,landing elevation angle,elevation angle from the ground,and maximum swing speed all decreased,and the postoperative increase;while the proportion of the extension and swing phases before surgery increased.Significantly decreased after surgery,and there was no significant difference between the reference values and the normal group after 3 months of reconstruction,indicating that the reconstruction of ACL under arthroscopy has a good improvement effect on the post-injury gait;3,Foot space pose assessment analysis system(Sennotech Insole X 1.0)can monitor the gait characteristics of patients after reconstruction of the fork ligament in real time,objectively record the changes of gait after ACL reconstruction,have certain reference value for evaluating the effect of surgery,and through data analysis,formulate a more reasonable An effective,targeted treatment plan to help patients better recover the physiological and motor function of the knee. |
