J Am Acad Orthop Surg Glob Res Rev 2023; 7:01979360-202311000-00011. [PMID: 37973030 PMCID: PMC10656085 DOI: 10.5435/jaaosglobal-d-23-00075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 07/26/2023] [Accepted: 08/30/2023] [Indexed: 11/19/2023]
Abstract
INTRODUCTION Tibial deformities are common, but substantial concern may be associated with corrective osteotomy regarding major complications reported in classic literature. Such studies chiefly focused on high tibial osteotomy, with relatively little investigation of other areas and types of deformity. The primary aim of this study was to identify the rate of compartment syndrome, vascular injury, nerve injury, and other major complications after elective tibial osteotomy. METHODS One hundred eight tibia osteotomies performed during 2019 to 2021 were evaluated, representing all tibia osteotomies except situations of existing infection. A retrospective chart review was performed to identify patient demographics, surgical indications, anatomic location of osteotomy, fixation used, and complications prompting additional surgery. RESULTS The most common osteotomy locations were high tibial osteotomy (35/108 = 32%, 32/35 = 91% medial opening, and 3/35 = 9% medial closing), proximal metaphysis (30/108 = 28%), and diaphysis (32/108 = 30%). The most common fixation was plate and screw (38/108 = 35%) or dynamic frame (36/108 = 33%). Tranexamic acid was administered to 107/108 = 99% of patients and aspirin chemoprophylaxis was used for 83/108 = 86%. A total of 33/34= 97% of anterior compartment prophylactic fasciotomies were performed for diaphyseal or proximal metaphysis osteotomies. No events of compartment syndrome, vascular injury, nerve injury, or pulmonary embolism occurred. One patient required débridement to address infection. Additional surgery for delayed/nonunion occurred for nine segments (8%). Additional surgery for other reasons were performed for 10 segments (9%), none resulting in reduced limb function. CONCLUSION Tibial osteotomy can be safely performed for a variety of indications in a diverse range of patients, without a notable risk of the most feared complications of compartment syndrome, vascular injury, and neurologic deficit. Prophylactic fasciotomy and reducing postoperative bleeding using tranexamic acid, along with location-specific safe surgical techniques, may help prevent major complications and thereby facilitate optimized deformity care.

Abstract
The supramalleolar osteotomy (SMO) is a joint-preserving surgical procedure that allows realignment of the ankle joint in severe deformity secondary to arthritis. This osteotomy realigns the mechanical axis to provide better weight distribution through the ankle joint. With an aligned mechanical axis, the overloaded asymmetric ankle joint will shift toward the preserved joint area in a valgus or varus ankle joint. The SMO also can be used via a staged approach to correct severe deformity in an end-stage arthritic ankle before total ankle arthroplasty to optimize the implant's longevity and improve overall functional outcomes.

Abstract
INTRODUCTION We investigated the mid-term outcomes of supramalleolar osteotomies regarding "survivorship" [before ankle arthrodesis (AA) or total ankle replacement (TAR)], complication rate and adjuvant procedures required. MATERIAL AND METHODS PubMed, Cochrane and Trip Medical Database were searched from January 01, 2000. Studies reporting on SMOs for ankle arthritis, in minimum of 20 patients aged 17 or older, followed for a minimum of two years, were included. Quality assessment was performed with the Modified Coleman Methodology Score (MCMS). A subgroup analysis of varus/valgus ankles was performed. RESULTS Sixteen studies met the inclusion criteria, with 866 SMOs in 851 patients. Mean age of patients was 53.6 (range 17-79) years, and mean follow-up was 49.1 (range 8-168) months. Of the arthritic ankles (646 ankles), 11.1% were classified as Takakura stage I, 24.0% as stage II, 59.9% as stage III and 5.0% as stage IV. The overall MCMS was 55.2 ± 9.6 (fair). Eleven studies (657 SMOs) reported on "survivorship" of SMO, before arthrodesis (2.7%), or total ankle replacement (TAR) (5.8%) was required. Patients required AA after an average of 44.6 (range 7-156) months, and TAR after 36.71 (range 7-152) months. Hardware removal was required in 1.9% and revision in 4.4% of 777 SMOs. Mean AOFAS score was 51.8 preoperatively, improving to 79.1 postoperatively. Mean VAS was 6.5 preoperatively and improved to 2.1 postoperatively. Complications were reported in 5.7% (44 out of 777 SMOs). Soft tissue procedures were performed in 41.0% (310 out of 756 SMOs), whereas concomitant osseous procedures were performed in 59.0% (446 out of 756 SMOs). SMOs performed for valgus ankles failed in 11.1% of patients, vs 5.6% in varus ankles (p < 0.05), with disparity between the different studies. CONCLUSIONS SMOs combined with adjuvant, osseous and soft tissue, procedures, were performed mostly for arthritic ankles of stage II and III, according to the Takakura classification and offered functional improvement with low complication rate. Approximately, 10% of SMOs failed and patients required AA or TAR, after an average of just over 4 years (50.5 months) after the index surgery. It is debatable whether varus and valgus ankles treated with SMO reveal different success rates.

INTERNATIONAL ORTHOPAEDICS 2023:10.1007/s00264-023-05822-w. [PMID: 37310443 DOI: 10.1007/s00264-023-05822-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 05/28/2022] [Accepted: 08/13/2022] [Indexed: 06/14/2023]
Abstract
PURPOSE There are controversies about combining distal tibia medial opening-wedge osteotomy (DTMO) with fibular valgization osteotomy (FVO) when performing supramalleolar osteotomy (SMO) for medial ankle osteoarthritis. This study aimed to assess the effect of FVO on the coronal translation of the mechanical axis by comparing the improvement of radiological indices after DTMO with and without FVO. METHODS Forty-three ankles (mean follow-up: 42.0 months) were reviewed after SMO. Among them, 35/43 (81.4%) underwent DTMO with FVO, while 8/43 (18.6%) underwent DTMO only. To evaluate the effect of FVO radiologically, the medial gutter space (MGS) and talus centre migration (TCM) were measured. RESULTS Post-operatively, MGS and TCM were not significantly different after DTMO only and DTMO with FVO. However, the improvement of MGS was significantly higher in the combined FVO group (0.8 mm (standard deviation [SD] 0.8 mm) vs. 1.5 mm (SD 0.8 mm); p = 0.015). More lateral translation of the talus was achieved in the FVO group (5.1 mm (SD 2.3 mm) vs. 7.5 mm (SD 3.0 mm); p = 0.033). However, the changes in the MGS and TCM were not significantly correlated with the clinical outcomes (p > 0.05). CONCLUSION Our radiological evaluation confirmed a significant medial gutter space widening and lateral talar translation after the addition of FVO. The SMO with fibular osteotomy allows greater shifting of the talus and, therefore, the weight-bearing axis.

Outcome measures in clinical studies of ankle osteoarthritis: a systematic review. Physiotherapy 2023; 118:54-63. [PMID: 36243563 DOI: 10.1016/j.physio.2022.08.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Revised: 06/08/2022] [Accepted: 08/26/2022] [Indexed: 02/04/2023]
Abstract
OBJECTIVE To explore and describe the outcome measures reported in primary research of ankle osteoarthritis (OA) and to propose aligned health-related domains. METHODS Six databases were searched, and studies were screened by two independent reviewers. Studies of participants with ankle OA who were> 18 years of age and reported outcome measure data were included. Non-English, animal, cadaveric, reviews, and studies with< 5 participants were excluded. Outcome measures were examined for content and mapped to health-related domains. RESULTS 1386 studies were identified, of which 547 met selection criteria - reporting 250 outcome measures. Most commonly reported measures were the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (n = 257 studies), plain radiographs to measure ankle alignment (n = 211), numerical rating scale for pain severity (n = 177) and goniometry to measure ankle range of motion (n = 148). Outcome measures were organised into 19 domains. The most common domains were pain severity (315 (58%) studies), ankle alignment (254 (46%)), ankle motion (181 (33%)), disability (169 (31%)) and health-related quality of life (128 (23%)). These domains fell into the Outcome Measures in Rheumatology (OMERACT) core areas of life impact and pathophysiological manifestations. CONCLUSION Many outcome measures are used in ankle OA research, most of which assess joint alignment, pain, and motion. Based on the outcome measures identified, we proposed 19 possible health-related domains, predominantly in the OMERACT core areas of life impact and pathophysiological manifestations of ankle OA. Clinicians and researchers can use this review in guiding selection of outcome measures.

Supramalleolar osteotomy for the treatment of ankle osteoarthritis leads to favourable outcomes and low complication rates at mid-term follow-up: a systematic review. Knee Surg Sports Traumatol Arthrosc 2023; 31:701-715. [PMID: 36151410 DOI: 10.1007/s00167-022-07144-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Accepted: 08/26/2022] [Indexed: 02/07/2023]
Abstract
PURPOSE The purpose of this systematic review was to evaluate both the clinical and radiographic outcomes following supramalleolar osteotomy (SMO) in patients with ankle osteoarthritis, and to analyse the level of evidence (LOE) and quality of evidence (QOE) of the included studies. METHODS A systematic review of the MEDLINE, EMBASE, and Cochrane Library databases was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies reporting clinical data following SMO for the treatment of ankle osteoarthritis were included and assessed. The level and quality of evidence of the included studies were also evaluated. RESULTS Twenty-four studies with 1160 patients (1182 ankles) were included. Overall, 78.8% patients presented with post-traumatic ankle osteoarthritis. The weighted mean AOFAS score improved from 52.6 ± 9.7 (range 33.8-78.4) preoperatively to 78.1 ± 5.7 postoperatively at weighted mean follow-up of 50.4 ± 18.6 months (range 24.5-99.0). The most frequently utilised radiographic parameter was the tibial anterior surface angle, which improved from a preoperative weighted mean of 86.3° ± 5.6° (range 76.0°-102.0°) to a postoperative weighted mean of 89.9° ± 3.7° (range 84.9°-99.6°). The complication rate was 5.1% with non-union as the most commonly reported complication (1.6%). Secondary procedures were carried out in 28.2% of patients, the most common of which was implant and hardware removal (17.6%). The failure rate was 6.8%. Two studies were LOE II, 3 studies were LOE III, and 19 studies were LOE IV. The mean Modified Coleman Methodology Score was 59.3 ± 6.6 and the mean MINORS criteria score of all the included studies was 9.5 ± 3.7. CONCLUSION This systematic review demonstrates good clinical and radiological outcomes, together with a low failure rate at mid-term follow-up following supramalleolar osteotomy in patients with ankle osteoarthritis. However, a moderate reoperation rate (28.2%) was reported. A low failure rate (6.8%) was reported, which must be interpreted in light of the shortcomings of the design of the included studies and a relatively short follow-up period. In addition, there is a low level and quality of evidence in the current literature with inconsistent reporting of data which underscores the need for further higher quality research to be conducted. Our review highlights that SMO may be an effective and safe procedure in the setting of early-to-intermediate-stage ankle osteoarthritis. LEVEL OF EVIDENCE IV.

Abstract
Ankle osteoarthritis (OA) is an important factor that causes pain and dysfunction after ankle joint movement. In early and mid-term ankle OA, supramalleolar osteotomy can delay the progression of disease and maximize the preservation of ankle joint function. Three-dimensional printing (3DP) technology has brought us new hope, which can improve the accuracy of osteotomy, reduce the number of fluoroscopy, reduce the amount of blood loss, and achieve personalized and accurate treatment. The data of 16 patients with ankle OA in our center from January 2003 to July 2020 were retrospectively analyzed and divided into the 3DP group and the traditional group according to different treatment methods. Seven patients in the 3DP group used the 3DP personalized osteotomy guide; nine patients were treated by traditional osteotomy. All patients were followed up for 13.9 ± 3.1 months after the operation. The operation time in the 3DP group was 126.4 ± 11.1 min, its intraoperative blood loss was 85.7 ± 24.1 mL, and its intraoperative fluoroscopy time was 2.4 ± 0.2, which were all significantly less than 167.3 ± 12.2 min, 158.3 ± 22.8 mL, and 5.8 ± 0.2 times in the traditional group (P < 0.05), respectively. In the 3DP group, its postoperative tibial anterior surface (TAS) angle was 90.6 ± 0.3° and the talar tilt (TT) angle was 2.2 ± 0.6°, which were all significantly different compared with its preoperative data of 83.4 ± 1.7 and 8.0 ± 1.5°, respectively (P < 0.05). Compared with traditional osteotomy, 3DP-assisted supramalleolar osteotomy for varus and valgus ankle OA can significantly shorten the operation time and reduce intraoperative bleeding and the frequency of intraoperative fluoroscopy; personalized 3DP osteotomy guides and models can assist in the accurate correction of varus deformity during operation, restore the lower limb alignment, and improve the biomechanical status of the lower limbs. In addition, the 3DP of porous tantalum has good histocompatibility, and its interface structure and porosity are more conducive to bone ingrowth. For complex bone defects and revision prostheses, matching implants can be printed individually, which could realize the personalized precise treatment.

Abstract
Supramalleolar osteotomy (SMO) is an effective treatment for intermediate-stage varus ankle osteoarthritis (OA). This study aimed to investigate how clinical outcomes were associated with radiological changes and cartilage regeneration shown on arthroscopy before and after SMO in patients with intermediate-stage varus ankle OA. Twenty-six cases with intermediate-stage varus ankle OA underwent SMO with at least 1 year of postoperative follow-up. Clinical assessment was performed preoperatively and postoperatively using the visual analog scale (VAS), American Orthopedic Foot and Ankle Society ankle-hindfoot (AOFAS) scores, and their associations with postoperative changes in tibial ankle surface angle (TAS), talar tilt, tibial lateral surface angle, and heel alignment ratio. The degrees of cartilage regeneration in the tibia plafond and talar dome were observed via second-look arthroscopy. Afterward, their associations with the corresponding clinical outcomes were analyzed. There were significant changes in the TAS, talar tilt, and heel alignment ratio (p < .001, for all). However, there were no significant changes in the tibial lateral surface angle (p = .864) at the final follow-up compared to its preoperative value. Postoperative changes in TAS (p = .013) and the degree of cartilage regeneration (p = .028) in the talar dome significantly influenced the final follow-up AOFAS score. Changes in the TAS angle and the degree of cartilage regeneration after SMO were predictors of clinical outcomes after SMO. In particular, greater changes in the TAS angle corresponded to better clinical outcomes.

Abstract
BACKGROUND The current surgical treatment plan for medium-term varus-type ankle arthritis is primarily supramalleolar osteotomy (SMOT), but the reliability of this procedure still lacks high-quality evidence-based medical studies, such as randomized controlled clinical trials and meta-analyses of comparative studies. OBJECTIVE The current study explored whether significant differences were present in the clinical effect, reoperation rate, complications, and failure rate of this type of surgery. METHOD Two researchers searched the relevant literature in seven databases, including PubMed, Cochrane Library, EMBASE, the China Biomedical Literature Database, the China Academic Journals Full-text Database, the Wanfang database, and the Weipu Chinese Science and Technology Journal Database. The retrieval time spanned the establishment of the specific database up to September 2020, and the literature was screened to determine their final inclusion in the study. RESULTS AND CONCLUSIONS A total of 20 studies were included, including one Chinese and 19 English language studies. The primary indicators included a definitive effect of SMOT on the treatment of medium-term varus-type ankle arthritis. Concerning secondary indicators, although the surgery effect was satisfactory, some patients may require follow-up surgery, which may be unsuccessful with complications. The study results showed that, based on existing literature reports, the effect of SMOT for varus-type ankle arthritis was a satisfactory surgical method with some clinical value for correcting the ankle force line and relieving or even reversing ankle arthritis. However, its risk of complications and failure rate were comparatively high and, accordingly, requires good preoperative planning and close communication with patients. Due to the limited sample size of this study, more data and longer follow-up times involving this type of surgery should be reviewed to confirm this conclusion.

Abstract
BACKGROUND Evidence-based literature identifying the age limit for low tibial valgization osteotomy (LTO) is lacking to date. We addressed the following research questions: (1) is LTO effective for ankle arthritis in patients over 65 years?; (2) does patients' age alter the effectiveness of LTO?; and (3) does preoperative Takakura stage affect the degree of correction in patients over 65 years? METHODS We retrospectively reviewed the radiographic and clinical findings of 49 cases which underwent LTO. Patients were divided into two groups according to age at operation (19 cases in group 1 aged ≥65 years and 30 cases in group 2 aged <65). Patients in a single group were regrouped into two subgroups according to preoperative Takakura stage (stage II + IIIA versus IIIB) to determine if the degree of correction varied in Takakura stage IIIB. RESULTS Significant changes in radiographic parameters were observed with no significant differences in the amounts of correction between groups 1 and 2. Comparison of Takakura stage II + IIIA in group 1 to that in group 2 and stage IIIB in group 1 to that in group 2 revealed no significant differences in the amounts of correction. CONCLUSION LTO could be indicated for patients over 65 years if patient selection was appropriate. LTO in patients over 65 years showed similar radiographic improvements to those in younger patients, and the correction was successfully maintained during the follow-up period. The correctional power of all radiographic parameters did not vary by preoperative Takakura stage. LEVEL OF EVIDENCE Level III, comparative series.

Tonogai I, Sairyo K. One-stage tibial deformity correction and ankle arthrodesis for ankle osteoarthritis and tibial malalignment after low tibial osteotomy. Int J Surg Case Rep 2021; 89:106624. [PMID: 34844197 PMCID: PMC8636806 DOI: 10.1016/j.ijscr.2021.106624] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Revised: 11/18/2021] [Accepted: 11/21/2021] [Indexed: 11/19/2022] Open
Abstract
Introduction There are no reports on one-stage corrective tibial opening wedge osteotomy and arthrodesis for osteoarthritis of the ankle and tibial malalignment after distal tibial osteotomy. Presentation of case The patient was a 70-year-old woman who presented with complaints of ankle pain and lower limb deformity after tibial osteotomy performed for ankle arthritis 17–18 years earlier. Clinical examination revealed marked swelling around the ankle joint and pain and tenderness at the joint line. Imaging showed tibial malalignment and severe osteoarthritic changes in the ankle. The patient had valgus deformity of 21° and recurvatum deformity of 4°. In two months, she admitted to Department of Orthopedics at Tokushima University Hospital in Japan and we performed one-stage corrective tibial opening wedge osteotomy and ankle arthrodesis with an anterolateral plate through a lateral longitudinal incision. After removal of the previous implants, the remaining articular cartilage and osteophytes were removed from the tibial and talar surfaces. After debridement of the talar trochlea and tibial plateau, the center of rotation and angular deformity of the tibia was cut transversely and a 1-cm bone graft obtained from the removed fibula was inserted into the osteotomy site, which decreased the tibial malalignment. An anterolateral locking plate was inserted over the anterior and lateral sides of the tibia, and the ankle was fused using 2 cannulated screws. Discussion The patient wore an above-knee splint for 6 weeks to avoid weight-bearing followed by gradual weightbearing with a brace thereafter. Osseous fusion was achieved after about 3.5 months. Radiographs obtained at the 2-year follow-up visit showed complete union of the tibia and talus. Full correction of valgus and recurvatum deformity was achieved, and the patient was able to perform daily activities with almost no pain. Conclusion We reported a rare case of ankle osteoarthritis and tibial malalignment that was successfully treated with one-stage corrective tibial opening wedge osteotomy and ankle arthrodesis using an anterolateral plate via a transfibular approach. Ankle osteoarthritis and malalignment can be followed by osteotomy. One-stage ankle arthrodesis and deformity correction should be considered. Anterolateral plate was useful for arthrodesis and correction.

A comparative biomechanical study of the Distal Tibia Nail against compression plating for the osteosynthesis of supramalleolar corrective osteotomies. Sci Rep 2021; 11:18834. [PMID: 34552116 PMCID: PMC8458440 DOI: 10.1038/s41598-021-97968-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Accepted: 07/21/2021] [Indexed: 11/09/2022] Open
Abstract
The Distal Tibia Nail (DTN; Mizuho, Japan) has demonstrated higher biomechanical stiffness to locking plates in previous research for A3 distal tibia fractures. It is here investigated as a fixation option for supramalleolar corrective osteotomies (SMOT). Sixteen Sawbones tibiae were implanted with either a DTN (n = 8) or Medial Distal Tibia Plate (MDTP; n = 8) and a SMOT simulated. Two surgical outcome scenarios were envisaged: "best-case" representing an intact lateral cortex, and "worst-case" representing a fractured lateral cortex. All samples were subjected to compressive (350 N, 700 N) and torsional (± 4 Nm, ± 8 Nm) testing. Samples were evaluated using calculated construct stiffness from force-displacement data, interfragmentary movement and Von Mises' strain distribution. The DTN demonstrated a greater compressive stiffness for the best-case surgical scenario, whereas the MDTP showed higher stiffness (p < 0.05) for the worst-case surgical scenario. In torsional testing, the DTN proved more resistant to torsion in the worst-case surgical setup (p < 0.05) for both ± 4 Nm and ± 8 Nm. The equivalent stiffness of the DTN against the MDTP supports the use of this implant for SMOT fixation and should be considered as a treatment option particularly in patients presenting vascularisation problems where the MDTP is an inappropriate choice.

Abstract
Teramoto distal tibial oblique osteotomy (DTOO) is a joint-preserving surgery for ankle osteoarthritis (AOA). However, there are few articles on the radiological assessment of DTOO. The purpose of this study was to report the clinical outcomes and radiological evaluations of weight-bearing radiographs before and after DTOO. We retrospectively reviewed 52 patients who underwent DTOO between 2007 and 2018. We recorded the Tanaka-Takakura classification, fixation methods, Japanese Society for Surgery of the Foot Ankle/Hindfoot Scale (JSSF scale), and complications. The tibial articular surface angle (TAS), medial malleolar angle (MMA), tibial lateral surface angle (TLS), talar tilt angle (TTA), and tibiotalar surface angle (TTS) were evaluated using weight-bearing ankle radiographs. The median patient age was 66 years, and the mean follow-up duration was 46 ± 23 months. Two stage 2, 9 stage 3a, 30 stage 3b, and 11 stage 4 according to the Tanaka-Takakura classification were performed using DTOO. The JSSF scale improved significantly from 39.9 ± 13.8 before surgery to 87.2 ± 7.5 after surgery. Seven cases were fixed using a locking plate, and 45 cases were fixed using a circular external fixator. The TAS, MMA, TLS, TTA, and TTS significantly changed before and after DTOO. Radiological evaluation indicated that DTOO influences talar behavior during weight-bearing, and improves the clinical outcomes of AOA.

Abstract
Osteochondral lesions of the talus (OLTs) are characterized by damage to the articular cartilage of the talus and its underlying subchondral bone. Up to 75% of OLTs are caused by trauma, such as an ankle sprain or fracture. Physical examination and imaging are crucial for diagnosis and characterization of an OLT. No superior treatment for OLTs exists. It is paramount that an evidence-based personalized treatment approach is applied to patients with OLTs because lesion and patient characteristics guide treatment. This current concepts review covers clinical and preclinical evidence on OLT etiology, presentation, diagnosis, and treatment, all based on the Amsterdam perspective.

Abstract
Introduction Ankle arthritis is one of the most disabling and painful conditions. Up to 37.5% of ankle arthritis presents as asymmetric arthritis with ankle malalignment. Supramalleolar osteotomy is a joint sparing operation, which aims to realign the ankle joint that will prevent progression of arthritis and relieve patient's symptoms. Aim The aim of this study is to analyse the medium term functional and radiographic outcomes of patients who underwent supramalleolar osteotomy for asymmetric ankle arthritis. Materials and methods This is a retrospective outcome study of medium term outcome for 33 patients who underwent Supramalleolar osteotomy for asymmetric ankle arthritis by a single surgeon. We assessed the functional outcome of the patients with AOFAS and VAS score. The radiological parameters measured were Tibial articular surface ankle (TAS), Hind foot alignment angle (HFA) and Talar tilt angle (TT). We used the paired Student's t-test to compare the preoperative and postoperative radiographic measurements, AOFAS and VAS scores. We set the significance level at P < 0.05. Results We had 21 patients who underwent lateral closing wedge osteotomy for varus deformity and 12 patients who underwent medial closing wedge osteotomy for valgus deformity. The mean followup was 72 months [29-73]. The mean AOFAS score significantly improved by 44.82 ± 7.97 (p < 0.0001). The VAS score significantly improved by 5.06 ± 1.41 (p < 0.0001). All the radiological parameters showed statistically significant improvement. All osteotomy united by 8-10 weeks. We had one case of late deep wound infection, which settled down with by metalwork removal. The arthritis progressed in three cases, two patients had fusion and one patient had ankle replacement. We had 90.9% survival rate for our osteotomy at 6 years. Conclusion Supramalleolar osteotomy is an excellent option for patients with asymmetric ankle arthritis with good functional and radiological outcome and good medium term survival rate.

Abstract
BACKGROUND Low tibial valgization osteotomy with medial opening wedge (LTO) is generally indicated for ankle arthritis with a small talar tilt (TT). We addressed the following research questions: the efficacy of LTO for more significant varus ankle arthritis, the effect of additional inframalleolar correction followed by LTO, and the preoperative or operation-related factors influencing postoperative TT decrease. METHODS We retrospectively reviewed the radiographic and clinical findings of 31 patients with more significant varus ankle arthritis (≥8 degrees) who underwent LTO or LTO plus inframalleolar correction. We grouped the included patients according to combination with inframalleolar correction and postoperative decreased TT. Furthermore, a binary logistic regression analysis was performed to determine the factors influencing postoperative TT decrease. RESULTS Even though the mean TT was unchanged postoperatively (from 12.1 to 9.9 degrees, P = .052), clinical parameters were significantly increased. In the group with concomitant inframalleolar correction, we found that TT was more corrected (3.9 vs 1.8 degrees, P = .023) with a greater lateralization of the talar center and a greater correction of the hindfoot alignment to valgus. The results of the binary logistic regression analysis showed a significant relationship between postoperative decreased TT and preoperative talar center migration (P = .016), hindfoot alignment angle (P = .033), hindfoot moment arm (P = .041), and hindfoot alignment ratio (P = .016). CONCLUSION LTO in more significant varus ankle arthritis could result in clinical improvement, although TT was not significantly changed. We recommend adding inframalleolar correction after LTO for the patients with more significant varus ankle arthritis. LEVEL OF EVIDENCE Level III, comparative series.

Abstract
The supramalleolar osteotomy is a joint-preserving surgical procedure. It is a very good treatment option for the asymmetric varus ankle and medial compartment osteoarthritis. The primary objective of the procedure is to shift medial concentration of stress toward the lateral intact articular cartilage to redistribute the joint loads during ambulation. Several studies have shown that deformities of the ankle result in uneven load distribution in the ankle joint, which eventually leads to articular cartilage degeneration. Since the lateral articular cartilage is intact, joint-sacrificing procedures such as total ankle replacement or ankle arthrodesis are not the most appropriate treatment choices for medial compartment arthritis. Results of supramalleolar osteotomies are very promising in terms of functional outcome and pain relief. In younger patients with medial compartment varus ankle osteoarthritis or even with a normal tibial anterior surface angle, supramalleolar osteotomies can be performed to realign the ankle to promote regeneration of the asymmetrically damaged cartilage. In this review article, we will discuss the indications, complications, surgical techniques, and outcomes of the supramalleolar osteotomy reported in the current literature.

Abstract
The varus ankle deformity can lead to osteoarthritis; therefore, numerous supramalleolar tibia osteotomy techniques are described to correct this deformity. Many of these techniques are more suitable for uniplanar ankle deformity. Particularly, if there are multiplane ankle deformities, the use of the six-axis deformity correction system may be successful in solving the problems which may occur during the correction. In this article, we report two cases of three plane deformities of ankle joint due to trauma sequelae, which were treated with supramalleolar osteotomy using a hexapod fixator which is called the Smart Correction Frame®.

Abstract
Malunion of ankle and pilon fractures has significant detrimental effect on function and development of post-trauma osteoarthritis. Unfortunately, the incidence of malunion has been reported to be increasing. It is important to assess the ankle for congruency, because this determines the level where correction will occur. A plethora of techniques are available, with low-level evidence supporting each, and therefore it is important that the treating surgeon is fully prepared and comfortable in the techniques they are to use. Supplementary procedures are common and should be expected. This article provides a review of current methods of treatment and their outcomes.

Abstract
OBJECTIVE Supramalleolar tibial osteotomy (SMO) for asymmetric ankle osteoarthritis (OA) is known to lead to satisfactory. Here, authors present a preliminary report on SMO surgical treatment in patients with asymmetric ankle arthritis. MATERIALS AND METHODS We reviewed cases of asymmetric ankle OA treated by modified SMO between January 2011 and October 2015. Clinical assessment was performed with the use of the ankle and hindfoot score of the American Orthopedic Foot and Ankle Society (AOFAS), foot function index, and visual analogue scale (VAS). Patient satisfaction with surgery and postoperative subjective symptoms were examined. Radiographic evaluation included preoperative and postoperative tibial anterior surface angle (TAS angle), talar tilt angle (TT angle), and tibial lateral surface angle (TLS angle). Takakura stage was measured. RESULTS The average follow-up period was 46.3 months. The AOFAS score was 55.7 ± 6.03 preoperatively and 76.0 ± 4.73 postoperatively. Foot function index was 60.7 ± 8.78 preoperatively and 30.8 ± 7.59 postoperatively. VAS was 7.2 ± 0.53 before surgery and 1.9 ± 0.85 after surgery. Clinical evaluations showed statistically significant improvement. The majority of patients reported satisfactory results in the subjective satisfaction evaluation. TAS angle was 84.6 ± 1.82 preoperatively and 94.0 ± 2.79 postoperatively. TLS angle was 78.8 ± 2.11 preoperatively and 81.8 ± 1.80 postoperatively. TT angle was 3.6 ± 1.26 before surgery and 2.1 ± 0.79 after surgery. Thirteen cases showed radiographic improvement of Takakura stage. Complications were not observed. CONCLUSION Modified SMO is a useful procedure that provides for the union and stability of osteotomy with the advantages of the existing SMO and can be performed without bone graft.

Abstract
BACKGROUND Thorough understanding of the morphometry of the ankle joint is crucial to optimize conservative and operative therapy of ankle joint disorders. Despite recent improvements, basic anatomic and biomechanical correlations of the ankle joint including the orientation of the ankle joint axis and joint morphology as its key biomechanical features are not sufficiently recorded to date. The aim of this study was the evaluation of the ankle morphometry to gain information about the ankle joint axis. MATERIAL AND METHODS In this study 98 high-resolution CT-scans of complete Caucasian cadaver legs were analysed. Using the software Mimics and 3-Matic (Materialize) 22 anatomic parameters of the talocrural joint were assessed, including the length, width and surface area of the tibial and talar articular areas. Additionally, the radii of the articular areas, the medial distal tibial angle and the height of the talar dome were determined. RESULTS The radius of the central trochlea tali was 44.6±4.1mm (mean±SD). The central trochlea tali arc length was 40.8±3.0mm and its width was 27.4±2.5mm. Additionally we determined 47.0±4.4mm for the tibial sagittal radius, 27.6±3.0mm for the tibial arc length and 27.4±2.5mm for the central tibial width. CONCLUSION The present study describes the three-dimensional morphometry of Caucasian ankle joints in detail. This dimensional analysis of the ankle joint will inform the development and placements of implants and prostheses.

Abstract
BACKGROUND Supramalleolar deformities require surgical correction to avoid posttraumatic osteoarthrosis of the knee or ankle joint and to prevent definitive treatment options, such as total ankle arthroplasty or arthrodesis of the ankle joint. Various methods for the operative correction of supramalleolar deformities have been described in the literature. OBJECTIVE What results can be achieved with focal dome osteotomy to correct posttraumatic supramalleolar deformities? MATERIAL AND METHODS A total of 10 patients (mean age 37 years) with a supramalleolar posttraumatic deformity were treated by focal dome osteotomy. The mean follow-up was 27 months (min. 6, max. 105 months), 5 patients were female and 5 male. The supramalleolar varus/valgus deformity was on average 20° (at least 12°, maximum 33°). Preoperative and postoperative mechanical axis and joint angles were determined on digital radiographs. The American Orthopedic Foot and Ankle Society (AOFAS) score was used to assess the clinical outcome. RESULTS In seven patients the anatomical leg axis could be restored. In three patients a residual deformity of 2.8° was observed. Bone grafting was not necessary in any of the cases. Of the patients eight had free ankle mobility and two showed an average movement limit of 30° compared to the contralateral side. Posttraumatic ankle arthrosis was not observed in the short-term and medium-term results. The mean AOFAS score of 80 points (minimum 70, maximum 98) documented a functionally good result. CONCLUSION Supramalleolar dome type osteotomy is a technically difficult method for acute correction of supramalleolar deformities. The functional results and complication rates are comparable to those in the literature for alternative osteotomy techniques.

Abstract
The most common cause for end-stage ankle osteoarthritis is posttraumatic, sometimes resulting from concomitant supramalleolar deformity. Aims of the supramalleolar osteotomy include restoring the lower-leg axis to improve intraarticular load distribution and retarding degeneration of the tibiotalar joint. Preoperative planning is based on conventional weight-bearing radiographs. Often advanced imaging, including computed tomography and/or MRI, is needed for a better understanding of the underlying problem. Postoperative complications are not uncommon, including progression of tibiotalar osteoarthritis in up to 25% within 5 years of all patients who have supramalleolar osteotomies.

Abstract
BACKGROUND Although it has been proposed that in mid-stage ankle osteoarthritis, the subtalar joint can compensate for deformities above the ankle joint, the evidence is weak. We thus investigated subtalar joint alignment in different stages of ankle osteoarthritis using weightbearing computed tomography (CT) scans. METHODS The subtalar joint of 88 patients with osteoarthritis of the ankle joint and a control group of 27 healthy volunteers were assessed. Subgroups were performed according to the ankle deformity (varus and valgus) and stage of ankle joint osteoarthritis. Subtalar joint alignment was assessed on weightbearing CT scans. RESULTS A more valgus subtalar joint alignment was found in patients with varus ankle osteoarthritis. No significant difference of the subtalar joint alignment was evident when comparing different stages of ankle osteoarthritis. CONCLUSIONS Varus ankles compensate in the subtalar joint for deformities above the ankle joint. Compensation does not correlate with the stage of ankle osteoarthritis.

Abstract
OBJECTIVE Restoration of physiological alignment of the distal tibia and thereby restoration of physiological loading of the ankle joint; joint preservation in asymmetric degenerative arthritis of the ankle. INDICATIONS Congenital deformities of the distal tibia; acquired deformities of the distal tibia; asymmetric degenerative arthritis with partially preserved cartilage. CONTRAINDICATIONS Absolute contraindications comprise severe nicotine abuse, Charcot arthropathy, peripheral polyneuropathy, relevant peripheral arterial vessel disease, poor local soft tissue condition, acute infection and extensive cartilage damage grade 3-4 in the Outerbridge classification in the complete joint. SURGICAL TECHNIQUE Medial and lateral open and closed wedge osteotomies and dome osteotomies of the distal tibia are used, and shortening, lengthening and derotating osteotomies of the fibula. POSTOPERATIVE MANAGEMENT For 6 weeks, 15-20 kg partial weight-bearing in a below knee cast or a walker orthosis; full weight-bearing depending on osseous healing after 9-12 weeks postoperatively. RESULTS Between July 2012 and May 2017, 15 patients (10 men, 5 women) underwent a supramalleor osteotomy. Average age was 41.8 years (range 17-63 years) and the retrospective average follow-up was 28.7 months (range 3-47 months). Mean preoperative AOFAS (American Orthopaedic Foot and Ankle Society) hindfoot score was 54.3 (range 26-86) and postoperatively a mean of 74.2 (44-100). Preoperatively, 9 patients had varus malalignment and 6 patients valgus malalignment; overall, 4 patients developed complications requiring surgical intervention (26.7%). Osteosynthetic material was removed in 60% of the patients.

Abstract
BACKGROUND Ankle distraction arthroplasty is one option for the treatment of severe ankle arthritis in young patients. The outcomes and factors predicting success in distraction arthroplasty are poorly understood. METHODS From January 2011 to May 2015, 16 patients who had undergone ankle distraction arthroplasty for ankle arthritis were operated, including six males and ten females. All patients were available for analysis. The main outcome measurements included joint space on weight bearing radiographs, AOFAS-AH scores (American Orthopaedic Foot & Ankle Society ankle-hindfoot score), VAS scores and SF-36 scores. RESULTS All 16 patients were followed for a mean follow-up of 40.9 ± 14.7 months (range, 17-67 months). Fourteen of the 16 patients still had their native ankle joints. One patient had undergone ankle arthrodesis 1 year after the operation and one patient had converted to spontaneous ankle fusion at the 3 years follow-up postoperative. The VAS score improved from 5.9 ± 0.8 to 3.7 ± 2.2 (p = 0.0028). The mean AOFAS-AH score improved from 41.9 ± 7.2 preoperatively to 68.1 ± 20.0 postoperatively (p = 0.001). The mean SF-36 score improved from 43.1 ± 7.6 preoperatively to 62.7 ± 18.8 postoperatively (p = 0.002). A weight-bearing ankle space larger than 3 mm at 1 year following distraction is a positive predictive factor. CONCLUSIONS In this study, the treatment of ankle motion distraction for end stage ankle arthritis showed benefit in 9/16 (56.25%) patients at 41 months. It is a promising method for young patients with severe ankle arthritis.

Abstract
Ankle osteoarthritis (AOA) is a severe pathology, mostly affecting a post-traumatic young population. Arthroscopic debridement, arthrodiastasis, osteotomy are the current joint sparing procedures, but, in the available studies, controversial results were achieved, with better outcomes in case of limited degeneration. Only osteotomy in case of malalignment is universally accepted as a joint sparing procedure in case of partial AOA. Recently, the biological mechanism of osteoarthritis has been intensively studied: it is a whole joint pathology, affecting cartilage, bone and synovial membrane. In particular, the first stage is characterized by a reversible catabolic activity with a state of chondropenia. Thus, biological procedures for early AOA were proposed in order to delay or to avoid end stage procedures. Mesenchymal stem cells (MSCs) may be a good solution to prevent or reverse degeneration, due to their immunomodulatory features (able to control the catabolic joint environment) and their regenerative osteochondral capabilities (able to treat the chondral defects). In fact, MSCs may regulate the cytokine cascade and the metalloproteinases release, restoring the osteochondral tissue as well. After interesting reports of mesenchymal stem cells seeded on scaffold and applied to cartilage defects in non-degenerated joints, bone marrow derived cells transplantation appears to be a promising technique in order to control the degenerative pathway and restore the osteochondral defects.

Abstract
Foot and ankle physicians in China encounter quite a large amount of severe and complex deformities. The main cause of severe ankle and foot deformity is trauma, while the other causes may be neuromuscular diseases, improper reduction and fixation and so on. Staged procedure may sometimes be a safer way to correct deformities in the presence of severe soft tissue contracture. Periarticular osteotomy combined with soft tissue balancing can be used in treating severe varus ankle arthritis, including stage IIIb cases and patients with talar tilt of more than 10 degrees.

Abstract
Supramalleolar osteotomies are a surgical treatment option for asymmetric varus or valgus ankle arthritis where at least 50% of the joint surface is spared. Procedure selection requires significant preoperative planning for appropriate execution. Thus, the surgeon must be familiar with the principles of deformity correction. With appropriate patient selection and proper preoperative planning, the procedure has been shown to yield excellent results, redistributing forces more evenly across the ankle joint by restoring the mechanical axis of the lower leg with minimal complications.

Abstract
Joint instability creates a clinical and economic burden in the health care system. Injuries and disorders that directly damage the joint structure or lead to joint instability are highly associated with osteoarthritis (OA). Thus, understanding the physiology of joint stability and the mechanisms of joint instability-induced OA is of clinical significance. The first section of this review discusses the structure and function of major joint tissues, including periarticular muscles, which play a significant role in joint stability. Because the knee, ankle, and shoulder joints demonstrate a high incidence of ligament injury and joint instability, the second section summarizes the mechanisms of ligament injury-associated joint instability of these joints. The final section highlights the recent advances in the understanding of the mechanical and biological mechanisms of joint instability-induced OA. These advances may lead to new opportunities for clinical intervention in the prevention and early treatment of OA.

Abstract
A variety of surgical procedures are utilized for management of ankle osteoarthritis. The most common etiology in patients with ankle osteoarthritis is post-traumatic often resulting in asymmetric ankle osteoarthritis with concomitant valgus or varus deformity. A substantial part of tibiotalar joint is often preserved, therefore, in appropriate patients, joint-preserving surgery holds the potential to be a superior treatment option than joint-sacrificing procedures including total ankle replacement or ankle arthrodesis. This review is designed to describe indications and contraindications for single-stage supramalleolar realignment surgery. Complications associated with this type of surgery and postoperative outcome are highlighted using recent literature.
