    Abstract: 〈 p 〉 Collaborative filtering-based models can use the interaction between users and products or the correlation between users and users, and between products and products. However, methods based on collaborative filtering can only grasp one type of relationship and still cannot fully fit. Various factors influencing user preferences make a lot of redundant information still not filtered out. We proposals a collaborative filtering model based on deep learning, which combines the item-item relationship learning in advance with a neural collaborative filtering network to effectually make recommendations. In the initial stage, learn low-dimensional vectors of compartments, and embed information that reflections the co-occurrence relationship between compartments. The prediction stage combines the trained embedding vector with the embedding vector of the module as a correction to the output result of the neural network. The benchmark data set MovieLens 1M is the experienced data set of this article, and the effectiveness of this method is verified on the data set. The experienced results are compared with some advanced methods on the data set. The results show that the model proposed in this paper is better than some methods based on collaborative filtering. 〈 /p 〉 〈 p 〉 & nbsp; 〈 /p 〉

    Abstract: This study aimed to compare the percutaneous oblique osteotomy (POO) and the open chevron osteotomy technique for correction of hallux valgus deformity at a 2‐year follow‐up. Methods This is a retrospective study of consecutive patients undergoing operative correction of hallux valgus using one of two techniques (POO vs open chevron osteotomy) from 2014 to 2018. Forty eight feet (41 patients) that underwent the POO was compared with 64 feet (58 patients) that underwent open chevron osteotomy. The hallux valgus angle (HVA), intermetatarsal angle (IMA) and American Orthopedic Foot & Ankle Society Hallux Metatarsophalangeal‐Interphalangeal scores (AOFAS‐HMI) were assessed preoperatively and postoperatively at the 1, 2‐year follow‐up. The Manchester–Oxford Foot Questionnaire (MOXFQ) were assessed preoperatively and postoperatively at the 2‐year follow‐up. The VAS score was collected preoperatively and on 2 weeks,1 year and 2‐year follow‐up. Results Both groups achieved significant correction of the hallux deformity. The HVA in the POO group during the follow‐up period were 12.5 ± 2.22 and 17.9 ± 9.31, respectively, and in the open chevron group were 14.1 ± 6.78 and 14.8 ± 7.83, respectively. The IMA in the POO group during the follow‐up period were 7.61 ± 1.63 and 6.94 ± 1.53, respectively, and in the open chevron group were 6.89 ± 3.06 and 6.97 ± 2.95, respectively. Postoperative MOXFQ scores in all domains were significantly improved in both groups, however there was no significant difference in the improvement of any domain between POO and open groups at a 2‐year follow‐up. The AOFAS HMI scores in the POO group during the follow‐up period were 86.5 ± 10.7 and 85.2 ± 13.8, respectively, and in the open chevron group were 88.2 ± 10.8 and 79.5 ± 23.7, respectively. The VAS scores in the POO group during the follow‐up period were 2.00 ± 0.98, 2.00 ± 0.99 and 1.55 ± 1.11, respectively, and in the open chevron group were 5.51 ± 1.45, 2.56 ± 2.88 and 2.56 ± 2.88 respectively. The 1‐year and 2‐year follow‐up outcomes between POO and open groups showed no significant difference regarding AOFAS HMI scores and VAS scores, however the POO group showed statistically significant improvement of VAS scores in the postoperative 2 weeks ( P 〈  0.001). There was no statistical significance between the POO and open group in terms of complications rates (8.3% vs 12.5%, P = 0.480). Conclusion The POO technique is reliable and shows a comparable outcome to the open chevron osteotomy. However, the POO technique shows significantly less pain in the first 2 weeks after surgery.

    In: Journal of Orthopaedic Surgery, SAGE Publications, Vol. 30, No. 3 ( 2022-09), p. 102255362211259-
    Abstract: The Brostrom-Gould procedure has been considered as a gold standard operative technique for chronic lateral ankle instability. Despite the popularity and excellent outcomes of the modified Brostrom procedure, some patients still experience recurrence of ankle instability. Few studies reported outcomes of revision reconstruction for patients with a failed modified Brostrom procedure. This study aimed to evaluate the outcomes of a percutaneous anatomic revision lateral ankle ligament reconstruction for patients with a failed modified Brostrom procedure. Methods From March 2017 to April 2020, 21 patients with persistent ankle instability after a modified Brostrom procedure underwent revision lateral ankle ligament reconstruction. The operation was performed through minimally invasive incisions. Functional assessment was performed using the Karlsson–Peterson ankle scoring system (KP) and the Visual Analogue Scale (VAS). The questionnaires of KP and VAS were completed before surgery and at the last follow-up. Patients’ subjective satisfaction level was graded as excellent, good, fair, and poor. Preoperative and postoperative anterior talar displacement and varus talus tilt angle in stress radiographs were recorded. Results The average age at the revision surgery time was 39.6years. The mean follow-up was 39.2months. The VAS score improved from 4.1 ± 1.5 preoperatively to 1.3 ± 1.3 at the final follow-up ( p 〈 .05). The KP score improved from 59.0 ± 20.2 preoperatively to 88.2 ± 9.6 at the last follow-up ( p 〈 .05). The mean varus talar tilt angle was 14.1 ± 3.9 mm preoperatively versus 4.9 ± 4.7 mm at the final follow-up ( p 〈 .05). The mean anterior talar displacement was 12.8 ± 2.2 mm versus 5.6 ± 3.7 mm at the last follow-up ( p 〈 .05). Conclusions The revision anatomic reconstruction of the lateral ligaments of the ankle is effective for patients with recurrent instability after a failed modified Broström procedure.

    Abstract: The timing and strategy for operative treatment of flatfoot are still controversial. The purpose of this study was to evaluate clinical outcomes and radiographic changes following calcaneal Z osteotomy combined with subtalar arthroereisis for severe adolescent flexible flatfoot. Methods: Data were analyzed for 16 patients (20 feet) who had flatfoot without tibialis posterior tendon dysfunction and were treated by calcaneal Z osteotomy combined with arthroereisis between October 2011 and February 2015. The mean age of patients at the time of surgery was 12.8 ± 1.4 years (range, 10-14 years). Preoperative and postoperative measurements included changes in hindfoot valgus angles; changes in talonavicular uncoverage angles on anteroposterior (AP) radiographic view; and changes in talo–first metatarsal angles, talar pitch angles, and calcaneal pitch angles on lateral radiographic view. The American Orthopaedic Foot & Ankle Society Ankle-Hindfoot Score (AOFAS-AH) was used to assess foot function. The mean follow-up was 18.9 ± 6.9 months (range, 13-33 months). Results: The hindfoot valgus angle improved from 14.9 ± 4.2 degrees to 2.3 ± 1.7 degrees. On the AP view, the preoperative and postoperative talonavicular uncoverage angles were 30.5 ± 9.4 degrees and 9.8 ± 4.8 degrees, respectively. On lateral radiographs, the preoperative talo–first metatarsal angle, talar pitch angle, and calcaneal pitch angle were −22.1 ± 7.9 degrees, 36.1 ± 4.4 degrees, and 14.4 ± 4.0 degrees, respectively. Postoperative lateral radiographs demonstrated talo–first metatarsal angle, talar pitch angle, and calcaneal pitch angle of −6.2 ± 4.7 degrees, 27.3 ± 4.9 degrees, and 19.0 ± 4.3 degrees, respectively. The AOFAS-AH score improved from 66.8 ± 24.1 preoperatively to 96.5 ± 3.4 postoperatively. Conclusions: For adolescents with flatfoot, calcaneal Z osteotomy combined with subtalar arthroereisis provided satisfactory results. Level of Evidence: Level IV, retrospective case series.

    Abstract: To investigate the characteristics and the results of realignment surgery for the treatment of malunited ankle fracture. Methods Thirty‐three patients with malunited fractures of the ankle who underwent reconstructive surgery at our hospital from January 2010 to January 2014 were reviewed. The tibial anterior surface angle ( TAS ), the tibiotalar tilt angle ( TTA ), the malleolar angle ( MA ), and the tibial lateral surface angle ( TLS ) were measured. Clinical assessment was performed with use of the American Orthopaedic Foot and Ankle Society ( AOFAS ) scale and visual analogue scale ( VAS ) scores, and the osteoarthritis stage was determined radiographically with the modified Takakura classification system. The Wilcoxon matched‐pairs test was used to analyze the difference between the preoperative and the postoperative data. Results The mean follow‐up was 36 months (range, 20–60 months). The mean age at the time of realignment surgery was 37.1 years (range, 18–62 years). Compared with preoperation, the TAS at the last follow‐up showed a significant increase (88.50° ± 4.47° vs . 90.80° ± 3.49°, P = 0.0035); similar results were observed in TTA (1.62° ± 1.66° vs . 0.83° ± 0.90°, P 〈 0.01) and MA (82.30° ± 8.03° vs . 78.70° ± 4.76°, P = 0.005). At the last follow‐up, the mean AOFAS score was significantly increased compared with the score at preoperation (44.5 ± 13.7 vs . 78.0 ± 8.9, P 〈 0.01). Significant differences in VAS scores were found at the last follow‐up (6.76 ± 1.03 vs . 2.03 ± 1.21, P 〈 0.01). There was no significant difference in the Takakura grade between the preoperation and the last follow‐up. One patient had increased talar tilt postsurgery; the postoperative talar tilt angle of this patient was 20°. One patient had progressive ankle osteoarthritis, and was treated by ankle joint distraction. Conclusions Realignment surgery for a malunited ankle fracture can reduce pain, improve function, and delay ankle arthrodesis or total ankle replacement. Postoperative large talar tilt and advanced stages of ankle arthritis are the risk factors for the surgery.

    Abstract: Takakura 3B ankle arthritis is featured as obliteration of ankle space with subchondral bone contact. Among these patients, some have medial distal tibial platform erosion. It is hard to treat this kind of patients. The purpose of this study was to evaluate the therapeutic outcomes of intra-articular opening osteotomy combined with lateral ligament reconstruction for Takakura 3B ankle arthritis with medial distal tibial platform erosion. Methods From September 2009 to May 2016, 17 patients with Takakura 3B ankle arthritis were reviewed, including 3 male and 14 female patients. All underwent the operation of intra-articular opening osteotomy combined with lateral ligament reconstruction. All patients were available for analysis. The main outcome measurements included TT angle, AOFAS score, VAS score, SF-36 scale, and AOS scale. Results All patients were followed for a mean follow-up of 87.2 months (range, 49 to 129 months). The VAS scale improved from 5.5 ± 1.6 to 2.3 ± 1.9. The mean AOFAS score improved from 47.7 ± 15.7 to 75.8 ± 12.0. The SF-36 scale improved from 41.6 ± 14.0 to 67.7 ± 14.6. The AOS improved from 60.9 ± 13.9 to 28.2 ± 17.7. The TT angle improved from 14.3 ± 5.0° to 5.3 ± 4.0°. The TAS and TLS changed from 83.4 ± 2.6° and 77.5 ± 2.3° to 90.7 ± 2.3° and 78.6 ± 2.2°. However, the LTAS was not corrected significantly. Conclusion Intra-articular opening osteotomy combined with lateral ligament reconstruction is an effective method to treat varus ankle arthritis with medial distal tibial platform erosion.
