RESUMO
PURPOSE: The safety and reliability of endoscopic Achilles tendon rupture repair are still concerning aspects. This study's aim is to evaluate an all-inside endoscopic semiautomatic running locked stitch (Endo-SARLS) technique. METHODS: Forty cases with acute Achilles tendon rupture were treated with the all-inside Endo-SARLS technique between 2020 and 2021. Under endoscopic control, the proximal tendon stumps were stitched with the running locked method using a semiautomatic flexible suture passer. The threads of the high-strength suture were grasped through the paratenon subspace and then fixed into calcaneal insertion with a knotless anchor. Magnetic resonance imaging (MRI), surgical time and complications were assessed. Achilles Tendon Total Rupture Score (ATRS), Achilles Tendon Resting Angle (ATRA) and Heel Rise Height Scale (HRHS) were utilised to evaluate final outcomes. RESULTS: The average follow-up time was 25.4 ± 0.4 (range: 24-32) months. Appropriate tendon regeneration was observed on MRI after 12 months. At the final follow-up, the median value of ATRS score was 95 (interquartile range: 94, 98). Furthermore, there is no significant difference between the injured and contralateral side in the average ATRA (18.2 ± 1.8 vs. 18.3 ± 1.9°, ns) and median value of HRHS [14.5 (13.3, 15.5) vs. 14.8 (13.5, 15.6) cm, ns]. No infection and nerve injuries were encountered. Thirty-nine patients reported that they resumed casual sports activity after 6 months. One patient had a slight anchor cut-out, due to an addition injury, which was removed after 5 months. CONCLUSIONS: An all-inside Endo-SARLS technique showed promising clinical results for acute Achilles tendon ruptures. This procedure reduces the risk of sural nerve injuries while establishing a reliable connection between the tendon stumps. LEVEL OF EVIDENCE: Level IV.

PURPOSE: The purpose of this study is to compare absorbable suture anchor with knotless anchor techniques for arthroscopic anterior talofibular ligament (ATFL) repair. METHOD: A multicenter retrospective study was performed with 185 patients, who had undergone an arthroscopic ATFL repair procedure using absorbable suture anchor or knotless anchor between May 2017 and October 2019. The follow-up time was a minimum of 18 months. Karlsson-Peterson score, visual analogue scale (VAS), and Cumberland ankle instability tool (CAIT) were evaluated. The complications were also recorded. RESULTS: One hundred and seven patients underwent one absorbable suture anchor repair procedure (Group A [A]), and the other seventy-eight patients underwent one knotless anchor repair procedure (Group B [B]). At the final follow-up, both Karlsson-Peterson score (A, pre 61.0 ± 8.0 vs post 93.5 ± 5.3, P < 0.001; B, pre 59.5 ± 8.2 vs post 92.4 ± 6.3, P < 0.001), VAS score (A, pre 5.0 ± 1.3 vs post 0.5 ± 0.7, P < 0.001; B, pre 5.5 ± 1.2 vs post 0.9 ± 1.0, P < 0.001), and CAIT score (A, pre 53.1 ± 12.0 vs post 93.1 ± 6.6, P < 0.001; B, pre 51.6 ± 12.0 vs post 93.1 ± 6.5, P < 0.001) improved significantly in both groups. There was no significant difference between the two groups regarding the Karlsson-Peterson score (A, pre 61.0 ± 8.0 vs B, pre 59.5 ± 8.2, n.s; A, post 93.5 ± 5.3 vs B, post 92.4 ± 6.3, n.s), CAIT score (A, pre 53.1 ± 12.0 vs B, pre 51.6 ± 12.0, n.s; A, post 93.1 ± 6.6 vs B, post 93.1 ± 6.5, n.s) and the change ranges of VAS (A, 4.5 ± 1.0 vs B, 4.6 ± 1.2, n.s). Anchor complications were easier to occur in Group B (0/107 vs 6/78, P = 0.007). Knot irritation slightly increased in Group A (10/107 vs 0/78, P = 0.006). No significant difference was found regarding total complication rates (A, 10/107 vs B, 6/78, n.s). CONCLUSION: Absorbable suture anchor and knotless anchor for arthroscopic ATFL repair produced similar clinical outcomes. The ankle stability scores increased significantly in both groups. However, the knotless anchor has a higher risk to loosen, deviated direction or break, while the absorbable suture anchor still has a slim chance of knot irritation. LEVEL OF EVIDENCE: III.

BACKGROUND: Minimally invasive reconstruction techniques are used for anatomical ligament construction of the lateral collateral ligament complex of the ankle, but the two key elements, the bone tunnel and the appropriate graft tension, for the identification of the anatomic location during the surgery are not clearly stated. METHODS: The patients with chronic ankle instability who received arthroscopic anatomic lateral ligament complex reconstruction were retrospectively analyzed. The anatomical location of the bone tunnel was performed under arthroscopy combined with fluoroscopy for accurate location of the bone tunnel entrance. The graft tension and routing were controlled under arthroscopic visualization. The clinical outcomes were assessed using the Karlsson-Peterson score, Sefton articular stability scale, and Visual Analogue Scale (VAS). The complications were recorded during the follow-up. RESULTS: A total of 18 patients were enrolled in this study. The mean follow-up was 33.33 ± 3.69 (range from 24 to 36) months. No patient had recurrence of ankle instability after the operation. According to the Sefton articular stability scale, 94.5% of the patients had excellent/good function. The mean value of the anterior drawer tests and the talar tilt angle examination were decreased. The mean of the Karlsson-Peterson score and the Visual Analogue Scale(VAS) score were both improved significantly. CONCLUSIONS: The anatomic reconstruction of the ankle lateral ligament complex to treat chronic ankle instability using the arthroscopy combined with the fluoroscopic technique could improve the clinical functions, satisfaction, and reduced pain of patients.

INTRODUCTION: Recently, endoscopically assisted Achilles tendon repair techniques have improved to overcome the surgical complications. However, the risk of sural nerve injury and the strength of repair are still the most concerning aspects. MATERIAL AND METHODS: Twenty three patients with acute Achilles tendon rupture were reviewed in the present study. We stitch the Achilles tendon above the ruptured site using the endoscopic locking loop suture technique, and the knotless anchor suture-bridge technique can be used to make the distal fixation of threads. The function was assessed using the muscle power (MRC0-5), ATRS scores, AOFAS ankle-hindfoot scores, and VAS scores at the final follow-up. RESULTS: The mean follow-up time was 15.74 ± 2.43 months (12-18). At the final follow-up, the average of the muscle power (MRC0-5), ATRS score, AOFAS ankle-hindfoot score, and VAS score are 4.74 ± 0.45, 97.83 ± 2.77, 96.52 ± 4.87, and 0.35 ± 0.49, respectively. Every patient returned to previous sports activity at 6 months postoperative. No wound infection and sural nerve injuries were encountered. Only one case suffers local irritation at the medial knotless anchor site. CONCLUSIONS: Endoscopic "internal splinting" repair for acute Achilles tendon rupture using locking loop stitch with suture-bridge technique leads to an expedited return to activity with a low risk of complications. LEVEL OF EVIDENCE: Level IV, case series.

OBJECTIVE: When the endoscopic Achilles tendon repair technique is utilized, direct stitching of the ruptured site is challenging due to the frayed tendon stumps. To explore whether undesirable coaptation of the tendon stumps influences the generation of the tendons. METHODS: This study is a retrospective analysis of 46 patients who underwent a modified endoscopic Achilles tendon rupture repair from October 2018 to June 2020. Patients were divided into two groups according to the coaptation of tendon stumps on postoperative ultrasonography. Group 1 included 17 cases with undesirable coaptation (<50%), and Group 2 included 29 cases with appropriate coaptation (≥50%). Magnetic resonance imaging (MRI) was obtained postoperatively at 3, 6, and 12 months to evaluate the tendon morphological construction. Clinical evaluations were performed using the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hind foot score, the Achilles Tendon Total Rupture Score (ATRS), muscle power, and the Achilles tendon resting angle at the final follow-up. Complications were also encountered. The Student's t-test and the Mann-Whitney U-test were used to assess differences among both groups. RESULTS: The mean follow-up time was 37.5 ± 10.6 months in Group 1 and 39.0 ± 11.6 months in Group 2, respectively. The average age in Group 1 is slightly older than in Group 2 (37.3 ± 6.1 vs. 32.7 ± 6.3, p = 0.021). The tendon cross-section areas and thickness increased initially and decreased later on postoperative MRI evaluation. It also showed a significantly higher signal/noise quotient (SNQ) in Group 1 at postoperative 3 months. At postoperative 6 and 12 months, the SNQ between both groups was similar. The AOFAS score (95.9 ± 5.1 vs. 96.2 ± 4.9, p = 0.832), ATRS score (97.0 ± 3.6 vs. 97.7 ± 3.3, p = 0.527), and muscle power (21.38 vs. 24.74, p = 0.287) were not significantly different between both groups. However, the resting angle of Group 1 was significantly larger than that of Group 2 (4.6 ± 2.4 vs. 2.4 ± 2.3, p = 0.004). There was no difference in the complications (p = 0.628). CONCLUSION: Although complete regeneration can be finally achieved, the early stage of tendon stump regeneration can be prolonged due to undesirable coaptation when endoscopic Achilles tendon repair technique is applied. The prolonged high signal duration on MRI indicates the less-than-ideal regeneration of the tendon, which might lead to elongation of the tendon.

BACKGROUND: Calcaneal Sanders type III or higher fractures traditionally have been treated with open reduction and internal fixation (ORIF); however, ORIF has associated complications. We investigated a combination of minimally invasive dual incision and internal fixation using mini plates for treating Sanders type III calcaneal fractures. METHODS: Twenty patients with Sanders type III intra-articular calcaneal fractures with a posterior subtalar articular displacement > 2 mm were included. Surgical outcomes were assessed by visual analogue scale (VAS) pain score, American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, and calcaneal geometry, including Böhler and Gissane angles. RESULTS: The Böhler angle, Gissane angle, and height and length of the calcaneus were increased following treatment. Based on the AOFAS score, 80% of cases had excellent or good outcomes. The mean postoperative VAS pain score was 1.6. Complications such as malunion or a screw positioning deviation occurred in 6 patients, and one patient experienced delayed wound healing. There were no wound infections. CONCLUSIONS: These results indicate that minimally invasive dual incision with mini plate internal fixation may be an effective alternative to ORIF for treating Sanders type III calcaneal fractures. Advantages include improvement of calcaneal geometry and a lower rate of wound infections.

BACKGROUND: There is still no definite consensus on whether arthroscopic repair shows superiority over open repair for chronic lateral ankle instability. We conducted a systematic review and meta-analysis of the current comparative studies to make a generalized analysis. METHODS: PubMed, Embase, and Web of Science databases were searched from inception to April 2020. Included studies were assessed by the level of evidence and quality of evidence (Cochrane Handbook or MINORS). The process of data extraction was conducted by two independent authors. The comparative results of clinical outcomes, stress radiographic outcomes, and complication rates between two groups were pooled. Statistical analysis was performed using STATA. RESULTS: Nine comparative studies for a total of 473 patients (250 arthroscopic repair, 223 open repair) were included. For the clinical outcomes, a significant difference was found in favor of arthroscopic repair with regard to AOFAS scores (MD 0.32, 95% CI 0.12 to 0.53, I2 = 7.7%, P = .370) and VAS scores (MD - 0.30, 95% CI - 0.54 to - 0.05, I2 = 48.3%, P = .102). No significant difference was found regarding to stress radiographic outcomes. Importantly, the total complication rate (RR 0.88, 95% CI 0.51 to 1.49, I2 = 0%, P = .957) as well as nerve complication rate (RR 1.21, 95% CI 0.53 to 2.75, I2 = 0%, P = .975) of arthroscopic repair group is not significantly different to that of open repair group. CONCLUSIONS: Arthroscopic repair for lateral ankle instability shows excellent clinical results comparable to open repair. Especially, arthroscopic repair might alleviate more pain due to the minimally invasive procedure. Patients receiving arthroscopic repair do not result in a higher total complication rate and nerve injury rate.

BACKGROUND: To explore the application and clinical efficacy of surgical approach strategies in open reduction internal fixation of closed complex tibial Pilon fractures based on axial CT scans. METHODS: This retrospective cohort study included data of 25 patients with closed complex tibial Pilon fractures treated from October 2011 to March 2014, including 19 males and 6 females aged 18-54 years (average 39.5 years). According to classification criteria of the Association for Osteosynthesis/Orthopedic Trauma Association (AO/OTA), 4 patients were type 43C1, 10 type 43C2, and 11 type 43C3. Surgical approaches were selected based on fracture line distribution and bone displacement revealed by axial CT scans, and an open reduction method was adopted for internal fixation of the bone plates. Postoperatively, Burwell-Charnley radiographic criteria were used to determine fracture reduction quality. Functional evaluation was performed using the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale. Complications, fracture union time, and the AOFAS scores at last follow-up were recorded. RESULTS: The 25 included patients were followed for 22-60 months postoperatively (average follow-up 33.9 months). Of these, 19 patients achieved anatomical reduction of the articular surface, 5 achieved good reduction, and one achieved fair reduction. Two patients developed superficial infection on the anteromedial incision and delayed union but recovered well after local dressing change and oral administration of antibiotics. Another patient developed deep infection on the anterolateral incision, which was controlled by debridement, catheter irrigation, and intravenous antibiotic injection. All fractures healed well and average union time was 2.8 months (range, 2-3 months). No fracture malunion or internal fixation failures were found at last follow-up. All 25 patients had AOFAS scores ranging from 80 to 100 at last follow-up (average 88.4). Overall, 15 patients were excellent, 10 good, and 0 fair or poor, with excellent and good rates of 100%. CONCLUSIONS: Surgical approach strategies for complex tibial Pilon fractures based on axial CT scans accurately reconstruct the articular surface and achieve solid internal fixation of assembled locking plates, while early postoperative functional exercises contribute to the functional recovery of affected limbs and reduce related complications.
