“…Despite the additional cost, Patient-speci c guide saves operation and uoroscopy time. 22] van Raaij T [23] report 3D virtually planned bone cutting and wedge guides are a promising approach associated with minimal postoperative deviation from the desired correction in medial opening supramalleolar osteotomy. And the technique makes it possible for a doctor lack of clinical experience to learn the osteotomy more quick [22] .…”

Purpose Degenerative joint disease (DJD) of the ankle is a chronic disease that can severely limit function and cause debilitating pain, and with the development of digital medicine, 3D printing patient-specific instrumentation has been used in many subjects. The purpose of the study was to compare the clinical and radiographic outcomes of 3D-printed patient-specific guides with the traditional open- wedge supramalleolar osteotomy . Materials and methods We retrospectively analyzed 10 patients with varus ankle osteoarthritis treated by open wedge supramalleolar osteotomy via 3D patient-specific instrument (PSI group) and 14 patients treated via the traditional method (control group). The demographic data and the pre- and post-operative TAS, TT, TLS angle were recorded. The AOFAS and VAS score were acquired pre-operatively and at the last follow-up time. Results All patients were obtained after surgery 49.4 ± 8.3 months (36–62) follow-up. The TAS, TT, TLS angle and VAS, AOFAS score was comparable pre-operatively between two groups(p＞0.05). The VAS and AOFAS score was statistically improved at the last follow-up time in both cohorts. And the TAS angle was significantly increased post-operatively in the overall cohort. The TT,TLS angle was also ameliorated, though insignificantly. The intraoperative fluoroscopy time, estimated blood loss, and operating time was statistically less in the PSI group in the two cohorts. The post-operative TAS, TT, TLS angle and VAS, AOFAS score at the last follow-up time was comparable between the two cohorts. Conclusion 3D-printed patient-specific guides have a short operation time, low intraoperative blood loss and less fluoroscopy frequency. Patient-specific guides can assist in facilitating doctor-patient communication, shortening the learning curve, reducing surgery time, and correcting varus deformity accurately. And the functional outcome was non-inferior to the traditional method.

“…To the best of our knowledge, SMOT has been shown to be effective in the correction of varus and valgus deformities of the ankle in adults and in the treatment of ankle arthritis [ 7 , 8 ], and it helps improve patients' quality of life [ 9 ]; nevertheless, there are not many reports on the efficacy of SMOT for the treatment of TAVD in adolescents at the developmental stage; therefore, the aim of this study was to retrospectively analyze the clinical data on the application of SMOT for the treatment of TAVD in adolescents at our institution and to evaluate the radiological and clinical outcomes of SMOT for the treatment of TAVD in adolescents.…”

Background Supramalleolar osteotomy (SMOT) has emerged as a valuable treatment for ankle varus deformity; however, there are fewer reports of treatment outcomes in adolescents. The purpose of this study was to investigate the radiologic and clinical outcomes of SMOT for the treatment of traumatic ankle joint varus deformity (TAVD) in adolescents. Methods We reviewed 32 adolescent cases who underwent SMOT between February 2017 and February 2022 for TAVD. Radiologic assessment included tibial anterior surface angle (TAS), talar tilt angle (TT), and tibial lateral surface angle (TLS) preoperatively and at 3 months and 12 months postoperatively, and clinical assessment was performed using American Orthopaedic Foot and Ankle Society (AOFAS) scores, Visual Analogue Scale (VAS) scores, and ankle dorsiflexion–plantarflexion ROM including preoperative and 6 months postoperative and 12 months postoperative. Results All 32 patients were followed up completely with a mean follow-up of (20.3 ± 3.2) months. From the radiologic outcomes, the mean preoperative TAS improved from 61.53 ± 3.74 to 88 ± 1.72 at 12 months postoperatively, the mean preoperative TT decreased from 2.25 ± 1.32 to 0.5 ± 0.57 at 12 months postoperatively, the mean preoperative TLS improved from 76.72 ± 0.21 to 79.34 ± 1.52 at 12 months postoperatively, the differences between the above preoperative and 12 months postoperative radiologic outcomes were statistically significant (p < 0.05), the mean preoperative AOFAS score improved from 65.5 ± 9.40 to 92.34 ± 4.00 at 12 months postoperatively, the mean preoperative VAS score decreased from 2.44 ± 1.24 to 0.78 ± 0.75 at 12 months postoperatively, and the mean preoperative range of motion (ROM) of ankle improved from 50.16 ± 7.46 to 55.78 ± 4.77 at 12 months postoperatively. The differences between the above preoperative and 12 months postoperative clinical results were statistically significant (p < 0.05). Conclusion Our study demonstrated that SMOT was effective in correcting TAVD and significantly improving ankle function in adolescents, and that it is an efficient and successful method for restoring ankle joint congruence and normal hindfoot alignment.
