ABSTRACT
Objective:To compare the location and efficacy of femoral tunnel near-isometric reconstruction of anterior cruciate ligament (ACL) between the transtibial and assisted medial approaches.Methods:The clinical data of 47 patients were retrospectively analyzed who had been admitted by Department of Orthopaedics, The 904 Hospital of PLA for ACL rupture from January 2018 to December 2019. They were divided into 2 groups according to different surgical approaches. In groups A of 21 cases, there were 15 males and 6 females with an age of (29.5 ± 4.8) years and their ACL was reconstructed through the transtibial approach with adjustable Endobutton plate; in group B of 26 cases, there were 18 males and 8 females with an age of (31.2 ± 9.6) years and their ACL was reconstructed through the assisted medial approach with adjustable Endobutton plate. The 2 groups were compared in terms of location of femoral tunnel, Lysholm score and International Knee Documentation Committee (IKDC) score at the last follow-up, and anterior-posterior and rotational stability of the knee joint.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). The 47 patients were followed up for 18 to 27 months (average, 22.3 months). As for the center of the inner opening of the femoral tunnel located by the four grid table method, the X-axis loci was 25.6% ± 2.5% and 26.7% ± 1.8% respectively in groups A and B, showing no statistically significant difference ( P>0.05) while the Y-axis loci 19.8% ± 2.0% and 30.6% ± 1.5% respectively in groups A and B, showing a statistically significant difference ( P<0.05). At the last follow-up, the lyholm scores were 90.9 ± 3.4 and 92.4 ± 3.9 and the IKDC scores 89.9 ± 3.5 and 90.2 ± 3.8 respectively in groups A and B, showing no significant difference between the 2 groups ( P>0.05). There was no significant difference either in the results of front drawer test, Lachman test or axial displacement test between the 2 groups ( P>0.05). Conclusion:In femoral tunnel near-isometric reconstruction of ACL, the transtibial approach can result in a tunnel location which is closer to the top of the condyle than the assisted medial approach, but both approaches can lead to satisfactory curative efficacy in the short postoperative period.
ABSTRACT
Objective:To evaluate the clinical efficacy of off-midline closure technique in the treatment of chronic pilonidal sinus.Methods:From July 2014 to July 2018, 59 patients suffered from chronic pilonidal sinus treated by off-midline closure were admitted to the Department of Proctology, Linyi Central Hospital, including 34 males and 25 females. According to the size and scope of the chronic pilonidal sinus, the off-midline flap was designed and sutured.Results:In this group of 59 patients, there were 52 cases of primary healing and 7 cases of incision complications, such as partial incision dehiscence and subcutaneous effusion. After follow-up for 2 years, no recurrence was observed. The scar was not obvious after wound healing. The patient was satisfied with the postoperative appearance.Conclusions:Using the off-midline closure technique to treat chronic pilonidal sinus can deviate from the midline to make the suture tension-free and the gluteal groove elevated. It not only effectively reduce the complication rate in patients, but also has high cure rate, low recurrence rate and does not affect appearance.
