Abstract Background: This is a five years follow-up report of some of the new devices for graft fixation. A two years follow-up data was published previously. As there were no statistically or clinically relevant differences in the results two years postoperatively, we hypothesize that after five years of follow-up there is no difference in the outcome after either cross-pin or absorbable interference screw fixation in ACL (anterior cruciate ligament) reconstruction with hamstring tendon autografts.Methods: 120 patients were randomized into four different groups (30 each) for ACL reconstruction with hamstring tendons: group I femoral Rigidfix cross-pin and Intrafix tibial extension sheath with a tapered expansion screw; group II Rigidfix femoral and BioScrew interference screw tibial fixation; group III BioScrew femoral and Intrafix tibial fixation; group IV BioScrew fixation into both tunnels. The evaluation methods were clinical examination, knee scores, and instrumented laxity measurements. Results: In this 5 years follow-up there were 102/120 (85%) patients available, but only 77 (64,2%) attended the clinical examinations. No significant difference between the groups in the clinical results was detected. There was a significant difference in additional procedures between the 2 and 5 years follow-up, group I had six additional procedures between the 2 and 5 years follow-up (P=.041). Conclusion: There was a statistically significant difference in the additional procedures, most in group I (six). None of these procedures found problems with the ACL graft. Other statistically or clinically significant differences in the 5 years follow-up results were not found. Study design: Randomized controlled clinical trial; Level of evidence, 1.Trial registration: ISRCTN registry with study ID ISRCTN34011837. Retrospectively registered 17.4.2020.

Supplemental Fixation

Background: Anterior cruciate ligament (ACL) reconstruction requires reliable and rigid graft fixation. Tibial-sided fixation is frequently cited as the “weak point” of the femur-graft-tibia construct. Some authors have recommended supplemental fixation with a staple or screw suture to post improve the strength and stiffness of the fixation. However, with these fixations, there is a risk for symptomatic hardware. Miniplate is flatter than screw or staple and does not penetrate the bone when attached. It is used as a button for suspensory fixation to enhance interference screw tibial fixation. Objective: To evaluate the clinical outcomes of the miniplate suture button for supplemental soft tissue graft tibial fixation in ACL reconstruction. Materials and Methods: A retrospective study was carried out between August 2016 and December 2019. A total of 40 patients had undergone primary ACL reconstruction, performed with hamstring tendon grafts that were secured using a miniplate suture button for supplemental interference screw tibial fixation. A total of 18 patients were excluded, leaving 22 patients at 1-year follow-up. Results: At least 1-year follow-up, the remaining 22 patients had significant difference between preoperative and postoperative outcome of anterior drawer test, Lachman test and pivot shift test (p<0.05). Lysholm knee scores improved significantly from 54.0±12.53 to 90.04±5.38. However, 3 patients (13.6%) experienced symptomatic hardware pain and 3 patients (13.6%) tendered around the miniplate site. There were no radiographic changes in miniplate displacement, deformed or broken plate, and bony reaction around miniplate. Conclusion: The use of a miniplate suture button as a supplemental fixation showed adequate fixation strength and showed good results in postoperative manual ligament laxity test and functional scores at minimum 1-year follow-up. However, there is still symptomatic pain at the hardware site. Keywords: Anterior cruciate ligament reconstruction, Supplemental fixation, Suture button

Background: Recurrent patellar instability is commonly treated with medial patellofemoral ligament reconstruction (MPFLR), and the use of allograft in anterior cruciate ligament reconstructions has demonstrated inferior outcomes. Purpose: To compare the outcomes of allografts versus autografts in adolescent MPFLR for patellar instability. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective chart review was completed on patients younger than 18 years who underwent MPFLR for recurrent instability after failed nonoperative management over an 8-year period with a minimum 2-year follow-up. Patients were divided into autograft or allograft hamstring cohorts for comparison. Primary outcome measures were return to normal activity, incidence of redislocation/subluxation, pain, stiffness, other complications, and Kujala scores. Statistical analysis using unpaired t tests was performed, with an alpha value set at P < .05. Results: After criteria were applied, 59 adolescents (36 allograft, 23 autograft; 38 girls, 21 boys) with a mean ± SD age of 15.2 ± 1.7 years and a mean follow-up of 4.1 ± 1.9 years (allograft, 3.3 ± 1.1 years; autograft, 5.7 ± 2.1 years; P ≤ .001) were included. Seven patients had concurrent osteotomies (3 allograft, 4 autograft), 11 patients had concurrent loose body removals (5 allograft, 6 autograft), and 9 patients had concurrent lateral release (7 allograft, 2 autograft). Between groups, no significant difference was found in change between preoperative and most recent follow-up (mean, 1.2 ± 2.1) or rate of return to sports (mean, 73.3%). In total, 9 surgeries failed (3 allograft, 6 autograft). For the surviving grafts, a statistical difference in mean Kujala scores at final follow-up was noted (allograft, 92.7; autograft, 97.4; P = .02). Conclusion: We identified no significant differences in return to activity, pain score changes, and incidences of failure between patients undergoing MPFLR with allograft versus autograft. Although teenagers with surviving autograft MPFLR reported statistically higher Kujala scores, the mean score difference of 5 points was not clinically significant. It appears that using allograft tendon instead of autograft tissue for MPFLR in this teenage population does not adversely affect long-term outcomes.

Background: Among the most important predictors of functional results of treatment of syndesmotic injuries is the accurate restoration of the syndesmotic space. The purpose of this study was to investigate the reduction performance of screw fixation and suture-button techniques using images obtained from computed tomography (CT) scans. Methods: Patients at or below 65 years who were treated with screw or suture-button fixation for syndesmotic injuries accompanying ankle fractures between January 2012 and March 2015 were retrospectively reviewed in our regional trauma unit. A total of 52 patients were included in the present study. Fixation was performed with syndesmotic screws in 26 patients and suture-button fixation in 26 patients. The patients were divided into 2 groups according to the fixation methods. Postoperative CT scans were used for radiologic evaluation. Four parameters (anteroposterior reduction, rotational reduction, the cross-sectional syndesmotic area, and the distal tibiofibular volumes) were taken into consideration for the radiologic assessment. Functional evaluation of patients was done using the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale at the final follow-up. The mean follow-up period was 16.7 ± 11.0 months, and the mean age was 44.1 ± 13.2. Results: There was a statistically significant decrease in the degree of fibular rotation ( P = .03) and an increase in the upper syndesmotic area ( P = .006) compared with the contralateral limb in the screw fixation group. In the suture-button fixation group, there was a statistically significant increase in the lower syndesmotic area ( P = .02) and distal tibiofibular volumes ( P = .04) compared with the contralateral limbs. The mean AOFAS scores were 88.4 ± 9.2 and 86.1 ± 14.0 in the suture-button fixation and screw fixation group, respectively. There was no statistically significant difference in the functional ankle joint scores between the groups. Conclusion: Although the functional outcomes were similar, the restoration of the fibular rotation in the treatment of syndesmotic injuries by screw fixation was troublesome and the volume of the distal tibiofibular space increased with the suture-button fixation technique. Level of Evidence: Level III, retrospective comparative study.

AbstractThe purpose of the current randomized clinical trial (RCT) was to evaluate the clinical outcomes of combined anterior cruciate ligament (ACL) and anterolateral ligament (ALL) reconstruction and to compare them with those of isolated ACL reconstruction. The hypothesis was that combined ACL and ALL reconstruction will result in superior clinical outcomes in terms of the rotational stability of the knee. This prospective RCT included 57 patients (44 men and 13 women, mean age = 31 ± 7.1 years) who underwent ACL reconstruction either isolated (Group I: 25 patients) or combined with ALL reconstruction (Group II: 32 patients). The evaluation of the patients was done preoperatively and postoperatively at 6 weeks, 12 weeks, 6 months, and 12 months including a clinical examination (Lachman's test, Pivot shift's test, and Rolimeter differential anterior laxity), an objective clinical scores (objective: the International Knee Documentation Committee [IKDC] score) and a subjective clinical scores (subjective: IKDC's score, Lysholm's score, and Tegner's activity score). Postoperative complications of all the patients were recorded. There was a significant difference between the study groups at all follow-up intervals when evaluating the postoperative pivot shift test (p < 0.05) with a superior rotational stability in the group of combined ACL and ALL reconstruction. At the final follow-up evaluation, 36% of the patients from Group I and 6.2% in Group II had a grade I positive pivot shift test (p < 0.05). There was a statistically significant difference between the two groups regarding the number of patients with a grade A IKDC objective score (p < 0.05) at the 6- and 12-month follow-up intervals (p = 0.007). There was a significant difference concerning the IKDC subjective score between the two study groups in favor of the combined ACL and ALL reconstruction group at 12 months postoperatively (p = 0.048). Combined ACL and ALL reconstruction technique was demonstrated to be effective in obtaining a superior control of the rotational knee instability and to improve the clinical objective and subjective outcomes when compared with isolated ACL reconstruction in sports patients with high-grade pivoting shifts.

Background: While few comparative studies exist, it has been suggested that open distal clavicle excisions (DCEs) provide inferior results when compared with the all-arthroscopic technique. Purpose: The purpose of this study was to compare the intermediate-term (5-year follow-up) results of patients undergoing arthroscopic versus open DCE for the treatment of recalcitrant acromioclavicular joint pain. Study Design: Cohort study; Level of evidence, 3. Methods: All patients who underwent an arthroscopic or open DCE between January 1999 and September 2006 were reviewed. Forty-eight patients (49 shoulders; 32 arthroscopic, 17 open) following DCE without significant glenohumeral pathologic changes were included. The mean follow-up for group I (open) and group II (arthroscopic) was 5.3 years and 4.2 years, respectively. The American Shoulder and Elbow Surgeons (ASES) score, visual analog scale (VAS) pain score, surgical time, and minimum radiographic acromioclavicular joint distance were calculated. Each patient completed a questionnaire assessing their scar satisfaction, percentage of normal shoulder function, and willingness to have the surgery again. Risk factors for poor outcomes were analyzed. Results: Arthroscopic patients had significantly less pain ( P = .035) by VAS (0.61 ± 1.02) compared with open (1.59 ± 2.15) at final follow-up. There was no significant difference between group I and group II with regard to ASES (87.5 ± 17.6 vs 94.6 ± 8.6), percentage of normal shoulder function (89.7% ± 12.5 vs 92.9% ± 8.6), average operative time (53.1 minutes vs 48 minutes), or radiographic resection distance (12.8 ± 2.1 mm vs 9.5 ± 2.9 mm). In the open group, patients with 16 of 17 shoulders were satisfied with their scar and 100% would do it again. In the arthroscopic group, patients with 31 of 32 shoulders (97%) were both satisfied and would have the surgery again. Conclusion: Open and arthroscopic DCE are both effective surgeries to treat recalcitrant acromioclavicular joint pain. At intermediate-term follow-up, they provide similarly good to excellent results with regard to patient satisfaction and shoulder function. Although both are effective treatments, less residual pain was found using the arthroscopic technique.

Abstract Background: ACL reconstruction surgeries is a common surgery that aim to provide stability and return functionality post ACL injury. Commonly, bone patellar tendon-bone (BPTB) and hamstring tendon autografts are used for the reconstruction. The choice of optimal autograft remains debatable to achieve satisfactory outcomes for various activities after reconstruction, including kneeling as widely needed, especially in prayers among Muslims. Kneeling with considerable ranges of motion and the minimum level of pain is still under rigorous investigations to choose proper autograft.Purpose: Hereby, we compare kneeling outcomes post-operatively using bone-patellar tendon-bone autografts with hamstring autografts for ACL reconstruction.Methods: A retrospective cohort study; Level of evidence (III) has enrolled. Adult patients underwent primary ACL reconstruction using either BPTB or HS autografts after they consented at a single institution with a minimum of 1-year as follow-up post-operatively were reviewed for assessment of the surgery’s outcomes in regards of kneeling pain and subjective assessment measures using International Knee Documentation Committee (IKDC) evaluation system.Results: A total of Thirty-two males were met our inclusion criteria. Analysis of data provided that 12 patients were in the BPTB group and 20 patients in the HS group. All patients show ACL rupture was sustained during participation in the athletic activity. After a follow-up of 1-year, there was no statistically significant difference between scores of two groups when comparing patient-reported outcome measures, with mean IKDC scores of 68.5 and 62.55 in the BPTB and HS groups, respectively. Interestingly, insignificant statistical differences observed in both groups regarding kneeling pain in the BPTB group when compared with the HS group.Conclusion: The findings of our study have shown that Arthroscopic ACL reconstruction using either hamstring autograft or bone patellar tendon autograft ends with equally reasonable satisfactory outcomes, with an insignificant difference in kneeling pain between both groups.

The aim of this in-vivo study was to evaluate/compare the clinical periodontal parameters in patients with true combined endo-perio lesions (EPL), treated with gutta-percha (GP) and mineral trioxide (MTA) as an obturation material alone and with addition of bone grafting in such lesions. 120 Saudi patients (mean age = 41yrs) diagnosed with true combined EPL participated in this study. Group I (control group, n = 30) was treated with conventional endodontic treatment using GP for obturation. Group II (n = 30) was treated with conventional endodontic treatment using MTA for obturation. Group III (n = 30) was treated with conventional endodontic treatment using GP for obturation + grafting procedure to fill the bony defect. Group IV (n = 30) was treated with conventional endodontic treatment using MTA for obturation + grafting procedure to fill the bony defect. Clinical parameters (Pocket depth (PD); Clinical attachment loss (CAL); keratinized tissue width (KTW); gingival phenotype (G.Ph.) and Cone Beam Computed Tomography Periapical Index (CBCTPAI)) were recorded and compared at baseline, 3, 6, 12 months’ interval. For the groups III and IV, CBCTPAI showed significant difference (p < 0.0001) with the other groups at 6 months and 1-year interval. The group with MTA + bone graft showed 76% and 90% patients with 0 score at 6 months and 1-year follow-up, respectively. Comparison of mean values of PD among study groups at 3 months, 6 months and 1 year showed significant difference at 3 months, whereas the mean PD values of subjects in GP + bone graft showed significantly higher PD values than other 3 groups (p = 0.025). Use of GP and MTA for root canal obturation along with periodontal therapy and bone augmentation helps in resolving complex endo-perio lesions. Bone grafting in addition to obturation with MTA was found to be the best treatment strategy in management of EPL cases and is recommended for clinicians who are treating EPL patients.

Abstract Background We hypothesized that 1st generation everolimus-eluting bioresorbable vascular scaffold (BVS) stent associated with less complication and less restenosis rate than everolimus-eluting stent (EES) in chronic total occlusion (CTO) recanalization guided by intracoronary imaging. Therefore, we aimed to assess the safety and performance of BVS stent in CTO revascularization in comparison to EES guided by intracoronary imaging. Our prospective comparative cross-sectional study was conducted on 60 CTO patients divided into two groups according to type of stent revascularization: group I (EES group): 40 (66.7%) patients and group II (BVS group): 20 (33.3%) patients. All patients were subjected to history taking, electrocardiogram (ECG), echocardiography, laboratory investigation, stress thallium study to assess viability before revascularization. Revascularization of viable CTO lesion guided by intracoronary imaging using optical coherence tomography (OCT). Then, long-term follow-up over 1 year clinically and by multi-slice CT coronary angiography (MSCT). Our clinical and angiographic endpoints were to detect any clinical or angiographic complications during the follow-up period. Results At 6 months angiographic follow-up, BVS group had not inferior angiographic parameters but without statistically significant difference (p = 0.566). At 12 months follow-up, there was no difference at end points between the two groups (p = 0.476). No differences were found at angiographic or clinical follow-up between BVS and EES. Conclusion This study shows that 1st generation everolimus-eluting BVS is non-inferior to EES for CTO revascularization. Further studies are needed to clearly state which new smaller footprint BVS, faster reabsorption, magnesium-based less thrombogenicity, and advanced mechanical properties is under development. We cannot dismiss the efficacy and safety of new BVS technology. Trial registration ZU-IRB#2498/3-12-2016 Registered 3 December 2016, email: [email protected]
