Comparison of curative effects from arthroscopic modified suture bridge and single-row modified Mason-Allen suture in repair of supraspinatus tendon tears / 中华创伤杂志

ABSTRACT

Objective To compare the early curative effects of arthroscopic modified suture bridge and single-row modified Mason-Allen suture in repair of supraspinatus tendon tears.Methods A retrospective case-control analysis was made on 28 patients with supraspinatus tendon tears admitted between June 2012 and June 2015.There were 16 males and 12 females,aged 43-63 years (mean,54.2 years).Thirteen patients (13 shoulders) were repaired using the arthroscopic modified suture bridge technique (Group A),and 15 patients (15 shoulders) were treated using the single-row modified Mason-Allen technique (Group B).Operation time and intraoperative blood loss were recorded.American shoulder and elbow surgeons (ASES) score,Constant score and visual analogue score (VAS) were used to evaluate the function and subjective outcomes preoperatively.Meanwhile,MRI was used for analysis of tendon integrity postoperatively.Results The operation time of Group A and B were (56.1 ± 23.2) minutes and (36.1 ± 15.6) minutes,respectively (P ＜ 0.05).The intraoperative blood loss was (30.3 ± 20.5) ml and (28.5 ± 18.2) ml,respectively (P ＞ 0.05).The average follow-up time for Groups A and B were 12 months and 12.6 months,respectively.The symptoms of 28 cases were alleviated after surgery,and the functions were obviously recovered.In Group A,thc VAS was decreased significantly from (7.0 ± 0.8) points preoperatively to (0.8 ± 0.8) points at final follow-up,ASES score was improved from (39.8 ± 3.1) points to (88.1 ± 4.8) points,and Constant score was improved from (54.8 ± 2.7) points to (88.2 ± 3.1) points (all P ＜ 0.05).In Group B,the VAS was decreased significantly from (6.8 ± 0.8) points preoperatively to (0.9 ± 0.8) points at final follow-up,ASES score was improved from (40.7 ± 2.5) points to (89.5 ± 3.2) points,and Constant score was improved from (56.0 ± 4.5) points to (89.3 ± 3.4) points (all P ＜ 0.05).There was no significant difference in the clinical outcomes between the two groups (P ＞ 0.05).The retear rate in Group B was 20％ (3/15),while no retear was presented in Group A (P ＜ 0.05).Conclusion Arthroscopic modified suture bridge technique and single-row modified Mason-Allen technique are both clinically effective for function recovery and pain relief in patients with supraspinatus tendon tears,but the former associated with lower incidence of tendon re-tear is preferred for moderate to large rotator cuff injury or rotator cuff injury with large insertion avulsion.
