Abstract
BACKGROUND While osteochondral autologous transplantation (OAT) offers favorable results in most patients with osteochondral lesions of the talus (OLT), some patients continue to experience persistent pain following the procedure. Information regarding the etiology of this pain and outcomes of revision surgery are limited. This study aimed to report results of revision surgery with realignment procedures in patients with failed OAT who demonstrated concomitant malalignment at the distal tibia or hindfoot. METHODS Eight patients (8 ankles), who had been experiencing persistent pain for more than 1 year following OAT, underwent realignment procedures during revision surgery. All patients underwent primary OAT for the treatment of medial OLTs. Patients were divided into 2 groups based on the main location of deformity: the supramalleolar realignment group (SRG, 5 ankles) and the hindfoot realignment group (HRG, 3 ankles). No direct procedure was performed on the osteochondral lesion at the time of revision surgery. Ankle and hindfoot alignment were evaluated using 6 parameters in weightbearing radiographs. Computed tomography (CT) was used to assess for medial gutter narrowing, spur formation, and cyst volume around transplanted osteochondral plug preoperatively and postoperatively. Clinical outcomes were assessed using Foot Function Index and Visual Analogue Scale. RESULTS All patients had medial gutter narrowing or spur formation, which are early signs of ankle arthritis. The SRG had varus distal tibial alignment with a median medial distal tibial angle of 85.7 degrees (interquartile range [IQR], 3.2). The HRG had valgus hindfoot alignment and a lower medial longitudinal arch with a median hindfoot moment arm of 8.4 mm (IQR, 6.1) and a median Meary's angle of 11.8 degrees (IQR, 1.4). Spontaneous restoration of the osteochondral lesion was observed after realignment surgery, with cyst volume decreasing from 0.2592 to 0.0873 cm3 (P < .05). Clinical scores improved in all patients. CONCLUSION The current study demonstrates the effectiveness of realignment surgery in a selected patient group who experienced persistent pain and showed radiographic evidence of malalignment after primary OAT. Our study provides evidence supporting the use of realignment procedures in these cases, with results indicating improved patient-reported outcomes and spontaneous restoration of osteochondral lesions.

Abstract
BACKGROUND Retrograde drilling remains technically challenging, because of the difficulty of identifying the accurate location of cysts during surgery. This study's aim was to evaluate the 3-dimensional (3D) image-based surgical navigation-assisted endoscopic retrograde drilling technique for subchondral bone lesions of the talus. METHODS From March 2017 to June 2020, a total of 21 cases with Hepple stage V subchondral bone lesions of the talus were treated with 3D image-based surgical navigation-assisted endoscopic retrograde drilling and bone graft technique. Arthroscopic views were categorized per Pritsch classifications. The correlation between the drilled tunnel with preoperative cystic lesions were assessed under postoperative computer tomographic (CT) scans. The American Orthopaedic Foot & Ankle Society (AOFAS) scores, visual analog scale (VAS) scores, and Foot and Ankle Ability Measure (FAAM) sports scales were evaluated at the preoperative and final consultation. All complications were recorded. RESULTS On postoperative CT scans, in 20 cases (95.2%), the drilled tunnel was judged to have been in the center of previous cysts. Only 9 cases (42.9%) showed intact normal cartilage (grade 0, group A); 12 cases (57.1%) had intact, but soft, cartilage (grade I, group B). The median follow-up time was 24 (24, 30) months, and at final follow-up, there were no significant differences between the mean AOFAS and VAS scores in both groups (89.0 ± 6.4 vs 88.3 ± 7.0 and 1 vs 0.5) or postoperative FAAM sports scales (28.2 ± 2.2 vs 26.6 ± 4.9, P = .363). Two patients had revision surgery in group B. CONCLUSION The 3D image-based surgical navigation-assisted endoscopic retrograde drilling and bone graft technique for the subchondral bone lesions of the talus in this small case series showed encouraging results.

Abstract
PURPOSE The purpose of this study was to retrospectively evaluate the clinical, arthroscopic and radiological outcomes of autologous osteoperiosteal transplantation for massive cystic osteochondral defects of the talus. METHODS Cases of autologous osteoperiosteal transplantation for medial massive cystic defects of the talus between 2014 and 2018 were reviewed. The visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score, Foot and Ankle Outcome Score (FAOS), and Ankle Activity Scale (AAS) were assessed preoperatively and postoperatively. The Magnetic Resonance Observation of Cartilage Tissue (MOCART) system and the International Cartilage Repair Society (ICRS) score were evaluated after surgery. The ability to return to daily activity and sport, as well as complications, were recorded. RESULTS Twenty-one patients were available for follow-up, with a mean follow-up of 60.1 ± 11.7 months. All subscales of preoperative FAOS had significant (P < 0.001) improvement at the final follow-up. The mean AOFAS and VAS scores significantly (P < 0.001) improved from 52.4 ± 12.4 preoperatively to 90.9 ± 5.2 at the last follow-up and from 7.9 ± 0.8 to 1.5 ± 0.9, respectively. The mean AAS decreased from 6.0 ± 1.4 preinjury to 1.4 ± 0.9 postinjury and then increased to 4.6 ± 1.4 at the final follow-up (P < 0.001). All 21 patients resumed daily activities after a mean of 3.1 ± 1.0 months. Fifteen patients (71.4%) returned to sports after a mean of 12.9 ± 4.1 months. All patients underwent follow-up MRI with a mean MOCART score of 68.6 ± 5.9. Eleven patients underwent second-look arthroscopy, and the average ICRS was 9.4 ± 0.8. No donor site morbidity was found in any patient during the follow-up. CONCLUSION Autologous osteoperiosteal transplantation provided favourable clinical, arthroscopic and radiographic outcomes in patients with massive cystic osteochondral defects of the talus during a minimum 3-year follow-up.

Abstract
BACKGROUND Autologous osteoperiosteal transplantation (AOPT) using graft harvested from the iliac crest is used to treat large cystic osteochondral lesions of the talus (OLTs). However, no studies have compared clinical and radiologic outcomes between AOPT and autologous osteochondral transplantation (AOCT) using graft harvested from the nonweightbearing zone of the femoral condyle of the ipsilateral knee in patients with large cystic OLTs. PURPOSE To compare clinical and radiologic outcomes between patients undergoing AOPT and those undergoing AOCT for large cystic OLTs. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Between March 2015 and March 2018, patients who underwent AOCT and AOPT to treat medial large cystic OLTs (>10 mm) were retrospectively evaluated. For comparability, the 2 groups were matched 1:1 based on their characteristics, including sex, age, body mass index, side of injury, follow-up period, and the preoperative cyst volume. After propensity score matching, 23 patients were enrolled in each group for the analysis. Clinical outcomes were assessed using the visual analog scale (VAS), the American Orthopaedic Foot & Ankle Society (AOFAS) score, and the Tegner score. Donor-site morbidity was recorded according to the symptoms, including pain, stiffness, swelling, and discomfort. In addition, the Lysholm score was used to assess the most common knee donor-site morbidity. Radiologic outcomes were evaluated using the magnetic resonance observation of cartilage repair tissue (MOCART) score, and the International Cartilage Regeneration & Joint Preservation Society (ICRS) score was obtained during second-look surgery. RESULTS The mean follow-up period was about 48 months. There were no significant differences in patient characteristics and lesion volumes between groups. Postoperative ankle pain VAS score, AOFAS score, and Tegner score were not significantly different between groups at final follow-up. Total donor-site morbidity (P = .004) and discomfort morbidity (P = .009) were significantly lower in the AOPT group than in the AOCT group. However, the Lysholm score showed no significant difference between the donor knee and the opposite knee (P = .503) in the AOCT group. The MOCART and ICRS scores were not significantly different between groups. CONCLUSION Clinical and radiologic outcomes of patients who underwent AOPT from the iliac crest were found to be comparable with those of patients who underwent AOCT from the ipsilateral knee for the treatment of medial large cystic OLTs. These results may be helpful for orthopaedic surgeons to decide appropriate treatments for patients with large cystic OLTs.

Abstract
INTRODUCTION The present study analyzed results in 56 osteochondral Mosaicplasty® autografts for osteochondral lesion of the talus (OLT) at more than 5 years' follow-up. HYPOTHESIS Mosaicplasty® shows long-term efficacy and low morbidity in the treatment of OLT. PATIENTS AND METHODS A multicenter retrospective study included patients treated by Mosaicplasty® with more than 5 years' follow-up. Preoperative data were collected from medical files, and all patients were reassessed. AOFAS scores and FAOS were calculated at last follow-up. Imaging comprised standard radiographs and MRI or CT arthrography of the ankle. RESULTS Fifty-six patients were included, with a mean age of 34 years (range, 18-60 years). Seventeen involved work accidents. Mean follow-up was 8.5 years (range, 5-20 years). Mean AOFAS score at follow-up was 80.6±19.4 and mean FAOS 77.8±21.5. Work accident, preoperative osteoarthritis and untreated laxity correlated significantly with poorer results. At last follow-up, 22 patients (39%) showed signs of osteoarthritis. There was no morbidity implicating the malleolar osteotomy. There were 11 cases (20%) of persistent patellar syndrome at the donor site. DISCUSSION The present results were comparable to those reported elsewhere, showing that functional results of Mosaicplasty® autograft for OLT do not deteriorate over the long term. Work accidents correlated significantly with poorer functional outcome. Any associated instability must always be treated. Malleolar osteotomy provides good exposure without additional morbidity.

Abstract
PURPOSE To compare the results of bone marrow stimulation (BMS) versus autologous osteochondral transfer (AOT) as primary surgical option for large cystic osteochondral lesion of talus (OLT) and to further distinguish factors associated with clinical failures and overall survival. METHODS We retrospectively analyzed patients with symptomatic large cystic OLT (>300 mm3) who underwent either primary BMS or AOT between January 2001 and January 2016 with a minimum follow-up of 36 months. Lesion surface area and volume were measured on magnetic resonance imaging. Clinical outcomes were assessed using pain visual analog scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score, and Foot and Ankle Outcome Score (FAOS). Survival outcomes and factors associated with clinical failures were evaluated using Kaplan-Meier analysis and Cox regression analyses, respectively. RESULTS Fifty of the total 853 patients had large cystic OLTs. Thirty-two patients underwent primary BMS, and 18 patients underwent primary AOT. Mean follow-up period was 118 months, and average lesion surface area and volume were 152.8 mm2 and 850.7 mm3, respectively. The primary AOT group showed significantly superior improvements in clinical outcomes compared with the BMS group at last follow-up (P = .001). Fourteen patients in the primary BMS group and 2 patients in the primary AOT group experienced clinical failure. Kaplan-Meier analysis showed a superior survival rate of primary AOT (P = .042). Syndesmosis widening (hazard ratio 12.361; P = .004) and large lesion surface area (hazard ratio 1.011; P = .014) were significant relative risks of clinical failure in the primary BMS group. However, lesion volume showed no significant relationship with clinical failure. CONCLUSION Long-term results of primary AOT showed superior clinical improvements and survival rate in treating large cystic OLT. Risk factors for failure in the primary BMS group were large lesion surface area and syndesmosis widening. STUDY DESIGN Retrospective comparative study LEVEL OF EVIDENCE: III.

Abstract
Objective To explore the feasibility of the repair and reconstruction of large talar lesions with three-dimensional (3D) printed talar components by biomechanical test. Methods Six cadaveric ankle specimens were used in this study and taken CT scan and reconstruction. Then, 3D printed talar component and osteotomy guide plate were designed and made. After the specimen was fixed on an Instron mechanical testing machine, a vertical pressure of 1 500 N was applied to the ankle when it was in different positions (neutral, 10° of dorsiflexion, and 14° of plantar flexion). The pressure-bearing area and pressure were measured and calculated. Then osteotomy on specimen was performed and 3D printed talar components were implanted. And the biomechanical test was performed again to compare the changes in pressure-bearing area and pressure. Results Before the talar component implantation, the pressure-bearing area of the talus varied with the ankle position in the following order: 10° of dorsiflexion > neutral position > 14° of plantar flexion, showing significant differences between positions ( P<0.05). The pressure exerted on the talus varied in the following order: 10° of dorsiflexion < neutral position < 14° of plantar flexion, showing significant differences between positions ( P<0.05). The pressure-bearing area and pressure were not significantly different between before and after talar component implantations in the same position ( P>0.05). The pressure on the 3D printed talar component was not significantly different from the overall pressure on the talus ( P>0.05). Conclusion Application of the 3D printed talar component can achieve precise repair and reconstruction of the large talar lesion. The pressure on the repaired site don't change after operation, indicating the clinical feasibility of this approach.

Abstract
Bone fractures are a worldwide public health concern. Previous studies have demonstrated that bone morphogenetic protein-7 (BMP7) gene transfer or mesenchymal stem cells (MSCs) transplantation may be a promising novel therapeutic approach. Therefore, the aim of the present study was to observe the effect of bone BMP7 transfer to MSCs on fracture healing. Bone marrow-derived MSCs (BMSCs) from New Zealand white rabbits were isolated and identified using flow cytometry. A recombinant BMP7 overexpressing adenovirus vector (Adv) was constructed and transfected into BMSCs. The expression of BMP7 was detected by reverse transcription-polymerase chain reaction, immunofluorescence and western blotting. The present study additionally investigated the effect of BMP7 on the differentiation capacity of BMSCs. Finally, tissue-engineered bone was created with support material to verify the effect of BMP7-BMSCs on fracture healing. The results demonstrated that the expression of BMP7 was increased at the mRNA and protein levels in BMSCs following transfection with BMP7 overexpressing Adv. The results additionally demonstrated that the expression of BMP7 enhanced the differentiation capacity of bone marrow mesenchymal stem cells and had a promotional effect on fracture healing. Overall, these data suggest that Adv-BMP7 is useful for introducing foreign genes into BMSCs and will be a powerful gene therapy tool for bone regeneration and other tissue engineering applications in the future.

Knee Surg Sports Traumatol Arthrosc 2018; 26:2158-2170. [PMID: 28687862 PMCID: PMC6061445 DOI: 10.1007/s00167-017-4629-0] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2017] [Accepted: 06/26/2017] [Indexed: 11/28/2022]
Abstract
PURPOSE The purpose of this systematic review was to identify the most effective surgical treatment for talar osteochondral defects after failed primary surgery. METHODS A literature search was conducted to find studies published from January 1996 till July 2016 using PubMed (MEDLINE), EMBASE, CDSR, DARE and CENTRAL. Two authors screened the search results separately and conducted quality assessment independently using the Newcastle-Ottawa scale. Weighted success rates were calculated. Studies eligible for pooling were combined. RESULTS Twenty-one studies with a total of 299 patients with 301 talar OCDs that failed primary surgery were investigated. Eight studies were retrospective case series, twelve were prospective case series and there was one randomized controlled trial. Calculated success percentages varied widely and ranged from 17 to 100%. Because of the low level of evidence and the scarce number of patients, no methodologically proper meta-analysis could be performed. A simplified pooling method resulted in a calculated mean success rate of 90% [CI 82-95%] for the osteochondral autograft transfer procedure, 65% [CI 46-81%] for mosaicplasty and 55% [CI 40-70%] for the osteochondral allograft transfer procedure. There was no significant difference between classic autologous chondrocyte implantation (success rate of 59% [CI 39-77%]) and matrix-associated chondrocyte implantation (success rate of 73% [CI 56-85%]). CONCLUSIONS Multiple surgical treatments are used for talar OCDs after primary surgical failure. More invasive methods are administered in comparison with primary treatment. No methodologically proper meta-analysis could be performed because of the low level of evidence and the limited number of patients. It is therefore inappropriate to draw firm conclusions from the collected results. Besides an expected difference in outcome between the autograft transfer procedure and the more extensive procedures of mosaicplasty and the use of an allograft, neither a clear nor a significant difference between treatment options could be demonstrated. The need for sufficiently powered prospective investigations in a randomized comparative clinical setting remains high. This present systematic review can be used in order to inform patients about expected outcome of the different treatment methods used after failed primary surgery. LEVEL OF EVIDENCE IV.

Abstract
Hyaline cartilage is avascular in nature, relying on surrounding synovial fluid for its nutrient supply. Lacking an inflammatory response, hyaline cartilage is unable to be repaired itself after injury. BMS technique allows reparative cartilage to be produced, taking the form of fibrocartilage. Fibrocartilage is weaker than hyaline cartilage. Various cartilage allograft materials are available for reparative techniques. The cartilage allograft materials discussed herein include fresh allograft transplantation, ACEM, and particulated juvenile articular cartilage.
