Objective To explore the effectiveness of the arthroscopic separate double-layer suture bridge technique in treatment of the delaminated rotator cuff tear. Methods Between May 2013 and May 2015, 54 patients with the delaminated rotator cuff tears were recruited in the study. They were randomly allocated into 2 groups to receive repair either using arthroscopic separate double-layer suture bridge technique (trial group, n=28) or using arthroscopic whole-layer suture bridge technique (control group, n=26). There was no significant difference in gender, age, injured side, tear type, and preoperative visual analogue scale (VAS) score, Constants score, American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles (UCLA) score, and the range of motion of shoulder joint between 2 groups (P>0.05). Postoperative functional scores, range of motion, and recurrence rate of tear in 2 groups were observed and compared. Results The operation time was significant longer in trial group than in control group (t=8.383, P=0.000). All incisions healed at stage Ⅰ without postoperative complication. All the patients were followed up 12 months. At 12 months postoperatively, the UCLA score, ASES score, VAS score, Constant score, and the range of motion were significantly improved when compared with the preoperative values in 2 groups (P<0.05). However there was no significant difference in above indexes between 2 groups (P>0.05). Four cases (14.3%) of rotator cuff tear recurred in trial group while 5 cases (19.2%) in control group, showing no significant difference (χ2=0.237, P=0.626). Conclusion Compared with the arthroscopic whole-layer suture bridge technique, arthroscopic separate double-layer suture bridge technique presents no significant difference in the shoulder function score, the range of motion, and recurrence of rotator cuff tear, while having a longer operation time.
Objective To compare the effectiveness of arthroscopic screw and suture fixations in treatment of anterior cruciate ligament tibial eminence avulsion fractures. Methods Between January 2002 and January 2009, 43 patients with freshanterior cruciate ligament tibial eminence avulsion fracture were treated, which were rated as types II and III according to Meyers- McKeever-Zaricznyj classification. Fractures were fixed with either screw (screw group, n=21) or nonabsorbable suture (suture group, n=22). There was no significant difference in sex, age, disease duration, and fracture type between 2 groups (P gt; 0.05). The range of motion (ROM) and Lysholm score were compared between 2 groups, and the knee stabil ity was evaluated based on the Lachman test and KT-2000 measurement. Results The operation time was 48-60 minutes (mean, 51.6 minutes) in the screw group, and 55-68 minutes (mean, 63.2 minutes) in the suture group, showing significant difference (t=4.645, P=0.032). Incisions healed by first intention and no compl ication occurred in 2 groups. All patients were followed up (5.7 ± 0.6) years in the screw group and (5.3 ± 0.5) years in the suture group. The fracture healed completely in both groups; the heal ing time was (3.3 ± 0.6) months in the screw group and (3.2 ± 0.4) months in the suture group, showing significant difference (t=3.723, P=0.019). Between the screw group and the suture group, no significant difference was found in ROM [(128.6 ± 10.1)° vs. (130.2 ± 14.1)°, P gt; 0.05] and Lysholm score (94.6 ± 14.5 vs. 95.1 ± 17.2, P gt; 0.05). The stabil ities based on KT-2000 measurement were also similar between 2 groups at last follow-up [(0.9 ± 0.3) mm vs. (1.0 ± 0.4) mm, P gt; 0.05]. Lachman test of 2 groups were negative. Conclusion Boththe screw and nonabsorbable suture fixation techniques for anterior cruciate l igament tibial eminence avulsion fracture (type II or III) have good results in terms of functional outcome and stabil ity. However, some patients show flexion contractures of 5° or 10°.
ObjectivesTo systematically review the efficacy of absorbable barbed suture versus traditional absorbable suture in total knee arthroplasty (TKA).MethodsPubMed, EMbase, The Cochrane Library, CBM, WanFang Data, CNKI and VIP databases were electronically searched to collect clinical trials of absorbable barbed suture versus traditional absorbable suture in TKA from inception to November, 2017. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 6 randomized controlled trials (RCTs) and 5 cohort studies were included, involving 2 008 patients. Meta-analysis showed that the joint capsule suture time of the absorbable barbed suture group [MD=–4.31, 95% CI (–4.72, –3.90), P<0.000 01], the incidence of acupuncture injury during suture [OR=0.14, 95% CI (0.03, 0.61),P=0.009], and incision complication rate [OR=0.56, 95% CI (0.36, 0.88), P=0.01] were significantly lower than the traditional absorbable suture group, but the incidence of suture fracture [OR=23.03, 95% CI (3.08, 172.09),P=0.002] was higher, yet the difference was statistically significant. There were no significant differences in the incidence of superficial infection, deep infection, aseptic redness, incision dehiscence and KSS score at 3 months after operation (P>0.05).ConclusionsAvailable evidence suggests that the use of absorbable barbed sutures to close the TKA surgical incision shortens the time to suture the joint capsule, reduces the incidence of acupuncture injury as well as the overall incidence of incision complications without increasing superficial infection, deep infection, and sterility. The incidence of redness and incision splitting has no significant effects on joint function at 3 months after surgery, however the incidence of suture fracture is higher. Due to limited quality and quantity of the included studies, the above conclusions are required to be verified by more high-quality studies.
ObjectiveTo explore the effectiveness of non-absorbable suture or suture anchor fixation by anterior approach in the treatment of anteromedial facet fractures of the ulnar coronoid process. MethodsBetween February 2007 and February 2012,16 cases of anteromedial facet fractures of the ulnar coronoid process were treated with operation.There were 9 males and 7 females,aged 20-80 years (mean,43.5 years).The causes of injury were traffic accident injury in 7 cases,tumble injury in 5 cases,and falling injury from height in 4 cases.The time from injury to operation was 6.8 days on average (range,2-8 days).All cases had closed fractures.According to O'Driscoll classification,there were 4 cases of type Ⅱ a,7 cases of type Ⅱ b,and 5 cases of type Ⅱ c.Among 16 patients,7 had simple anteromedial facet fractures of the ulnar coronoid process,and 9 had associated injury,including terrible triad in 3,Monteggia fractures in 4,and olecranon fractures in 2.All fractures were fixed with non-absorbable suture in 10 cases,and with suture anchor in 6 cases.The Mayo Elbow Performance Score (MEPS),range of motion (ROM),and complications were used to assess the elbow function. ResultsThe incisions all healed by first intension,without neurovascular injury.Fifteen patients were followed up 10-48 months (mean,25.3 months).The X-ray films showed that all fractures healed,with the mean healing time of 17.5 weeks (range,11-30 weeks).At last follow-up,the mean MEPS score was 88.5(range,55-100);the results were excellent in 10 cases,good in 3 cases,fair in 1 case,and poor in 1 case,with an excellent and good rate of 86.7%.The mean ROM of flexion and extension was 118°(range,35-145°),and the mean ROM of forearm rotation was 138°(range,85-165°).One case had elbow instability,and 3 had slight pain.No heterotopic ossification and traumatic arthritis occurred during the follow-up. ConclusionThe anteromedial facet fractures of the ulnar coronoid process can be clearly exposed through anterior approach,and the fracture fixation using non-absorbable suture and suture anchor fixation usually can restore the elbow function.
Objective To investigate the early effectiveness of three-point suture technique in treatment of anterior cruciate ligament (ACL) tibial eminence avulsion fracture by arthroscopy. Methods Between January 2016 and December 2017, 12 patients with ACL tibial eminence avulsion fractures underwent arthroscopic fixation of avulsion fractures with Ethibon suture using three-point suture technique. There were 9 males and 3 females, with an average of 36.4 years (range, 18-50 years). The fracture caused by traffic accident in 10 cases and sports in 2 cases. Among them, 1 patient was old fracture and 11 was fresh fracture. According to the modified Meyers-McKeever classification criteria, the fractures were rated as type Ⅲ in 7 cases and type Ⅳ in 5 cases. There were 2 cases of medial collateral ligament injury and medial meniscus injury. The preoperative International Knee Documentation Committee (IKDC) score was 37.9±4.7 and Lysholm score was 46.0±3.7. Results All operations completed smoothly. The operation time was 45-70 minutes (mean, 61.3 minutes). The incisions healed by first intention in all patients. The hospitalization stays ranged from 4 to 9 days (mean, 5 days). All patients were followed up 3-20 months (mean, 9.3 months). The anterior drawer test, Lachman test, and axis shift test in all patients were negative after operation. At last follow-up, the IKDC score was 89.7±2.5 and Lysholm score was 90.2±1.9, which were significantly higher than those before operation (t=–30.94, P=0.00; t=–33.03, P=0.00). At last follow-up, the X-ray films showed 9 cases of fracture anatomical reduction and 3 cases of almost anatomical reduction, and 12 cases of fracture healing. Conclusion For ACL tibial eminence avulsion fracture, arthroscopic three-point suture technique can effectively restore the stability of knee joint and obtain satisfactory early effectiveness.
Objective To evaluate the effect of releasable sutures on shallow anterior chamber, filtering bleb and long-term intraocular pressure (IOP). Methods We searched MEDLINE (1971 to 2007), OVID (1971 to 2007) and National Science and Technology Library (1971 to 2007). Randomized controlled trials (RCTs) of the effect of releasable sutures on trabeculectomy were collected. Study selection and assessment, data collection and analyses were undertaken and cross-checked by two reviewers. Meta-analyses were performed with The Cochrane Collaboration’s RevMan 4.2.10 software. Results Six RCTs involving 341 eyes were included. Significant differences were observed in the reduction of postoperative shallow anterior chamber (RD –0.23, 95%CI –0.31 to –0.14, Plt;0.000 01) and functional filtering blebs (RD –0.15, 95%CI –0.27 to –0.02, P=0.02). But, no differences were observed for the control of long-term IOP (SMD –0.13, 95%CI –0.37 to 0.10, P=0.27). Conclusion The evidence currently available showed that releasable sutures could reduce the incidence of shallow anterior chamber and has no beneficial effect in controlling long-term IOP. The current evidence is insufficient to define the efficacy of maintaining functional filtering blebs. Further large-scale, high-quality randomized controlled trials are needed.
ObjectiveTo investigate the surgical technique and effectiveness of arthroscopic ULTRA-Braid suture plane fixation for anterior cruciate ligament (ACL) tibial eminence avulsion fractures. MethodsBetween June 2012 and October 2014, 16 cases of ACL tibial eminence avulsion fracture were treated with ULTRA-Braid suture plane fixation under arthroscopy. There were 10 males and 6 females, aged from 17 to 38 years (mean, 25.8 years). The left knee was involved in 5 cases and the right knee in 11 cases. The causes were traffic accident injury in 9 cases, falling from height injury in 4 cases, and sports injury in 3 cases. The average interval from injury to operation was 7 days (range, 5-10 days) except 1 patient who received operation at 6 weeks after injury. The knee joint swelling was obvious; the result of Lachman test was positive; and the knee joint Lysholm score was 45.38±9.87. According to classification standard introduced by Meyers-McKeever-Zaricznyj, 7 cases were rated as type Ⅱ, 8 cases as type Ⅲ, and 1 case as type Ⅳ, excluding ligament and meniscus injury. ResultsAll the incisions healed by first intention. The patients received follow-up of 6-18 months (mean, 10 months). The postoperative X-ray and CT showed anatomic reduction (12 cases) or near anatomic reduction (4 cases); all fractures healed at 6 months after operation. The result of Lachman test was negative in the other 15 patients except 1 patient (Ⅱ degree). One patient had slight knee pain at 6 months postoperatively, and pain symptom disappeared after 1 year; the other cases resumed daily activities. Lysholm score at last follow-up was 98.13±2.34, showing significant difference when compared with preoperative score (t=-20.801, P=0.000). ConclusionArthroscopic ULTRA-Braid suture plane fixation for ACL tibial eminence avulsion fractures is an effective procedure with the advantages of minimal trauma, reliable fixation, satisfactory functional recovery, and simultaneously avoiding the second surgery.
Objective To explore the early effectiveness of arthroscopic tri-anchor double-pulley suture-bridge in treatment of medium-size supraspinatus tendon tears. Methods Between December 2020 and January 2023, 40 patients with medium-size supraspinatus tendon tears were treated with arthroscopic tri-anchor double-pulley suture-bridge. There were 18 males and 22 females, with an average age of 62.6 years (mean, 45-73 years). Among them, 17 patients had trauma history. The main clinical symptom was shoulder pain with hug resistance test (+). The interval from symptom onset to operation was 10.7 months on average (range, 3-36 months). Visual analogue scale (VAS) score, University of California Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and shoulder range of motion (ROM) of forward flexion, abduction, and external rotation were used to evaluate shoulder function. MRI was performed to assess the structural integrity and tension of reattached tendon. Patient satisfactions were calculated at last follow-up. Results All incisions healed by first intention, no complications such as incision infection or nerve injury occurred. All patients were followed up 12-37 months (mean, 18.2 months). At 12 months after operation, VAS score, UCLA score, and ASES score significantly improved when compared with the preoperative scores (P<0.05). At 3 and 12 months after operation, the ROM of external rotation significantly improved when compared with preoperative one (P<0.05), and further improved at 12 months after operation (P<0.05). However, the ROMs of abduction and forward flexion did not improve at 3 months after operation when compared with those before operation (P>0.05), but significantly improved at 12 months after operation (P<0.05). Twenty-six patients underwent MRI at 3-6 months, of which 23 patients possessed intact structural integrity, good tendon tension, and tendon healing; 3 patients underwent tendon re-tear. The self-rated satisfaction rate was 92.5% at last follow-up. Conclusion Arthroscopic tri-anchor double-pulley suture-bridge in treatment of medium-size supraspinatus tendon tears can maximize the tendon-bone contact area, obtain satisfied early effectiveness with high satisfaction rate and low incidence of tendon re-tear. However, the function of abduction is limited at 3 months after operation, and patients need to adhere to rehabilitation training to further improve the joint activity.
