RESUMEN
Background: Humeral lateral condyle fracture is the most common elbow fracture in children after supracondylar fractures. Non-union of these fractures may cause ulnar nerve deficit, deformity and loss of joint motion, which are difficult to manage. Treatment of lateral condyle non-union can be done in two stages or one stage. However, despite all types of treatment, the chance of success is very variable. Many complications such as avascular necrosis, loss of motion, non-union, chronic pain, and heterotopic ossification have been reported as a result of surgeries performed for lateral condyle pseudoarthrosis. Objective: In this article, we applied two-stage surgical treatment to a pediatric patient who developed ulnar neuropathy and elbow valgus deformity as a result of lateral condyle non-union. Case report: A 8-year-old boy with lateral condyle nonunion presented to our clinic with pain and deformity. After initial examination, two-stage surgical treatment was planned to achieve union and deformity correction. In the first stage, we performed pseudoarthrosis surgery and ulnar nerve anterior transposition, and in the second stage, we performed elbow valgus deformity correction surgery. In three year follow-up, the range of elbow was 130/5/0 flexion/extension, with full supnation and pronation. Carrying angle was same with the opposite side. Conclusion: Pediatric humeral lateral condyle nonunions cause deformity, pain, loss of motion, instability and neuropathy. Surgical treatment of nonunions with a careful planning provide excellent clinical and functional results.
RESUMEN
OBJECTIVE: Correction of a proximal tibial valgus deformity. INDICATIONS: Lateral osteoarthritis of the knee or cartilage damage in a valgus deformityâ¯> 5° with a medial proximal tibial angle (MPTA) >â¯90°. CONTRAINDICATIONS: Medial proximal tibial angle <â¯90°, medial cartilage damage, medial meniscus loss. SURGICAL TECHNIQUE: Skin incision medial of the tibial tuberosity approximately 8-10â¯cm. Insertion of two converging guidewires directly above the pes anserinus, ascending obliquely, and ending at the tip of the fibula. Control of the wire position with the image intensifier. Osteotomy with an oscillating saw. Removal of the wedge and closure of the osteotomy. Osteosynthesis with a medial angle-stable plate. POSTOPERATIVE MANAGEMENT: Partial load bearing with 10-20â¯kg for 2 weeks, then step-wise increase in load. Mobility: free. RESULTS: We performed this surgery in the manner described in 21 patients with lateral osteoarthritis or cartilage damage (17 men, 4 women, average age: 51 years). The valgus deformity was reduced from an average of 5.6 to -0.5°. The KOOS-PS (Knee Injury and Osteoarthritis Outcome Score-Physical Function Short-form) score decreased significantly from 39.1⯱ 14 to 25.8⯱ 20 points.
RESUMEN
BACKGROUND: In revision total knee arthroplasty (TKA), there is little information on the magnitude of potential limb lengthening, risk factors for lengthening, or its impact on patient-reported outcome measures. We aimed to quantify limb length alteration during revision TKA and assess risk factors for lengthening. METHODS: We identified 150 patients over a 3-year period who underwent revision TKA and had preoperative and postoperative EOS hip-to-ankle standing radiographs. The average patient age was 64 years, 51% were women; 68% had a preoperative varus deformity and 21% had a preoperative valgus deformity. Outcomes assessed included change in functional and anatomic limb length, risk factors for lengthening, and clinical outcome scores, including the Knee Osteoarthritis Outcome Score Joint Replacement, and the Veterans RAND 12-item Physical and Mental Scores. RESULTS: There were 124 patients (83%) who had functional limb lengthening, and 108 patients (72%) had anatomic limb lengthening. Patients had an average functional limb lengthening of 7 mm (range, -22 to 35) and an average anatomic limb lengthening of 5 mm (range, -16 to 31). Patients undergoing revision for instability experienced significantly greater anatomic lengthening (7.6 versus 4.6, P = .047). Patients who had ≥ 10° of deformity were more likely to be functionally lengthened (91 versus 79%) and had significantly greater average functional lengthening (12 versus 6 mm; P = .003). There was no significant change in clinical outcome scores at 6 weeks and 1 year for patients lengthened ≥ 5 or 10 mm compared to those not lengthened as substantially. CONCLUSIONS: There is major potential for functional and anatomic limb lengthening following revision TKA, with greater preoperative deformity and revision for instability being risk factors for lengthening.
RESUMEN
Small bone involvement caused by Mycobacterium tuberculosis infection is an uncommon clinical entity. Usually, the condition is linked to the spread of bacteria from the lungs. It is rather uncommon for people without pulmonary seeding, trauma, or a history of tuberculosis to experience isolated episodes of spina ventosa. We describe a rare case of an immunocompetent Indian woman, aged 25, who complained of swelling in her left thumb. The diagnosis of primary tubercular dactylitis of the thumb was made after a thorough clinical and laboratory workup, and she received conservative treatment.
RESUMEN
Introduction: In the treatment of medial gonarthrosis, the high tibial osteotomy (HTO) is recognized as an effective joint-sparing surgical procedure. Severe valgus deformity is not a common complication after HTO. There are no cases in the literature reporting valgus deformity of 10° or more after HTO. Case Report: An open-wedge HTO was performed on a 57-year-old female patient due to left knee pain and varus deformity. In this case, a progressive and severe valgus deformity occurred during follow-up. The severe valgus deformity was then corrected using an inverted V-shaped (hemi-closing, hemi-opening) HTO. Conclusion: Valgus deformity after HTO is not common. There are various factors that can lead to post-HTO valgus deformity; although no cases of valgus deformity exceeding 10° have been described. Intra-operative releasing of the superficial medial collateral ligament and associated lateral hinge fracture was a risk factor for overcorrection. This case aims to uncover the factors contributing to the development of severe valgus deformity subsequent to HTO and to present solutions for its management.
RESUMEN
INTRODUCTION: The modified 5-item frailty index (mFI-5) has been recently proposed as a useful tool for predicting postoperative complications in orthopedic surgery. We aimed to analyze the utility of this score in predicting complications and reoperations after hallux valgus (HV) deformity surgery. METHODS: 551 patients undergoing percutaneous HV corrective surgery were retrospectively reviewed. The mFI-5 was calculated based and patients were categorized in three groups: 1) non-frail: patients without any of the 5 comorbidities, 2) pre-frail: patients with one comorbidity and 3) frail: patients with two or more comorbidities. Complications and surgical reoperations were recorded. RESULTS: In the study period 772 percutaneous surgeries were performed to correct HV deformity, 551 patients were included with a median age of 60 (IQR 48-70). Three hundred eighty-nine patients were non-frail (70.6%), 132 were pre-frail (23.9%) and 30 were frail (5.4%). 75 patients suffered complications (13.6%). Even though the rate of complications was higher in frailty patients (23.3%) compared with pre-frail (13.6%) and non frail (12.8%), no significant differences were observed among groups. 48 patients required reoperation (8.7%) but the rate of reoperations among frailty groups was not significantly different (P=.11). Frailty patients had worse AOFAS scores at final follow up (P=.011). CONCLUSION: The mFI-5 was not useful to predict postoperative complications and reoperations after hallux valgus corrective surgery. Therefore, other factors should be considered when analyzing the risk of complications after HV corrective surgery.
RESUMEN
Common peroneal nerve (CPN) injury is a serious complication following total knee arthroplasty (TKA). We aim to report four patients (five knees) who underwent prophylactic peroneal nerve decompression for severe rigid valgus deformity with or without associated fixed flexion deformity that was not correctable under anaesthesia. The preoperative deformity of 31.1° valgus by femorotibial angle (range 22.6-37.9°) improved to 7.1° valgus (range 4.3-9.1°) postoperatively (p < 0.05). For two knees, varus-valgus constrained was used due to medial laxity and the other three had posterior-stabilised prosthesis. All four patients had normal motor or sensory nerve function of the CPN nerve postoperatively. There was a significant improvement in the functional outcome by knee society score and knee society functional score from 17.8 ± 6.8, 25 ± 16.2 to 84 ± 8.7, 83 ± 10.3, respectively (p < 0.05). No complications were noted in the mean follow-up of 1.2 years. Prophylactic peroneal nerve decompression allows safe, adequate and optimal lateral soft-tissue release. It is effective in preventing common peroneal nerve palsy in high-risk patients like severe valgus and flexion deformity during total knee arthroplasty.
RESUMEN
Introduction: Valgus deformity is characterized by an outward angulation of the knee joint. The most common cause of valgus deformity is osteoarthritis (OA), a prevalent progressive joint disease that causes chronic pain and functional limitations. Total knee replacement (TKR) is rarely done in patients with grade-I valgus deformity and young age. To the best of our knowledge, this is the first case report of its kind. Case Report: A 34-year-old man presented to us with 15 years of persistent, progressively worsening right knee pain that was interfering with his daily activities. No non-operative treatment could alleviate his severe pain. Physical examination revealed a positive valgus stress test, limited knee extension, and an asymmetrical gait. He was diagnosed with a grade-I valgus deformity of the right osteoarthritic knee. History, physical examination, and radiological findings confirmed the diagnosis. In consideration of severe pain and impaired quality of life, we opted to perform TKR using a medial parapatellar approach. Regular follow-ups were done after the procedure. He experienced no pain or recurrence of deformity. He was very satisfied with the result. His Western Ontario and McMaster Universities OA Index score at 12 months following surgery was 5, indicating a favorable outcome. Conclusion: This case exhibits the effectiveness of TKR in treating grade-I valgus deformity of the osteoarthritic knee with severe pain in a young adult, resulting in improved pain alleviation, mobility, joint alignment, and overall quality of life.
RESUMEN
Knee osteoarthritis (OA) is surgically treated with total knee arthroplasty (TKA). Traditionally, TKA has been performed using a mechanical alignment (MA) philosophy. However, due to significant patient dissatisfaction with surgical outcomes, an alternate alignment approach, kinematic alignment (KA), has gained popularity. KA-TKAs have improved functional patient outcomes by restoring the patient's native joint line orientation and minimizing soft tissue releases compared to neutral alignment in MA-TKAs. This review explores the postoperative effectiveness of utilizing KA-TKA to treat knee OA in patients with preoperative varus and valgus deformities. A comprehensive literature search was conducted on PubMed and Biomed Central databases, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The literature search focused on studies analyzing the postoperative TKA outcomes in knee OA patients with preoperative varus or valgus deformities whose surgeries followed a KA philosophy and those comparing KA-TKA with MA-TKA. The available clinical evidence indicates that KA-TKA can be a viable treatment option for individuals with knee OA. The alignment of phenotypes has little clinical significance concerning functional outcomes and implant survival rates following KA-TKA. Furthermore, surgery outcomes in patients with preoperative deformities who underwent KA-TKA were similar to those who underwent MA-TKA. KA-TKA produced significantly better functional outcomes than MA-TKA in certain aspects. However, studies with larger sample sizes and more extended follow-up periods that directly compare KA-TKA with MA-TKA in treating knee OA patients are needed to fully demonstrate the efficacy of each technique. Furthermore, further research into the effects of KA-TKA on implant survival rates will provide a better understanding of the benefits of this technique and ultimately lead to improved patient outcomes.
RESUMEN
Hallux valgus deformity (HVD) involves subluxation of the first metatarsophalangeal joint. While HVD is primarily considered a forefoot condition, midfoot instability may play a significant role in its development and severity. However, very few studies have placed a heavy emphasis on studying this phenomenon. Therefore, this review had a particular focus on understanding midfoot instability based on weightbearing imaging assessments of the TMT joint. This review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and searched five databases for studies on midfoot instability in HVD patients. The severity of HVD was defined by hallux valgus angle (HVA) and distal metatarsal articular angle (DMAA). Data was extracted, and articles were graded using the Methodological Index for Non-Randomized Studies (MINORS). Of 547 initially retrieved articles, 23 met the inclusion criteria. Patients with HVD showed higher HVA and DMAA on weightbearing radiographs (WBRG) and weightbearing computed tomography (WBCT) compared to healthy individuals. Midfoot instability was assessed through intermetatarsal angle (IMA) and tarsometatarsal angle (TMT angle). Patients with HVD exhibited greater IMA and TMT angles on both WBRG and WBCT. This review highlights the importance of weightbearing imaging assessments for midfoot instability in HVD. IMA and TMT angles can differentiate between healthy individuals and HVD patients, emphasizing the significance of midfoot assessment in understanding HVD pathology. These findings validate the limited evidence thus far in the literature pertaining to consistent midfoot instability in HVD patients and are able to provide ample reasoning for physicians to place a larger emphasis on midfoot imaging when assessing HVD in its entirety.
RESUMEN
BACKGROUND: The purpose of this study is to investigate the biomechanical effect of medial displacement calcaneal osteotomy (MDCO), subtalar joint fusion (SF), and medial ligament reconstruction (MLR: deltoid-spring ligament) in a severe flatfoot model. We hypothesized that (1) combination of MDCO and SF improves the tibiotalar and foot alignment in severe progressive collapsing foot deformity (PCFD) cadaver model. (2) However, if a residual valgus heel alignment remains after MCDO and SF, it can lead to increased medial ligament strain, foot malalignment, and tibiotalar valgus tilt, which will be mitigated by the addition of MLR. METHODS: Ten fresh-frozen cadaveric foot specimens were used to create a severe flatfoot model. The foot alignment changes, including the talo-first metatarsal angle in the axial and sagittal planes, subtalar angle, and tibiotalar angle in the coronal plane, were measured. The angles were measured at the initial condition, after creating the severe flatfoot model, and after each successive reconstructive procedure in the following order: (1) MDCO, (2) SF, and (3) MLR. RESULTS: Tibiotalar valgus tilt was decreased with the MDCO procedure: 4.4 vs 1.0 degrees (P = .04). Adding in situ SF to the MDCO led to increased tibiotalar tilt to 2.5 degrees was different from the initial condition (P = .01). Although the tibiotalar valgus tilt was significantly decreased after adding the MLR to the MDCO/SF procedure compared with the severe flatfoot model (0.8 vs 4.4 degrees, P = .03), no significant difference in the tibiotalar valgus tilt was observed between MDCO/SF and MDCO/SF with MLR. CONCLUSION: Our results demonstrated that MDCO significantly improved forefoot abduction and medial arch alignment, with no significant additional improvement observed with addition of SF. Following SF, a residual valgus heel alignment can contribute to subsequent tibiotalar valgus tilt. The addition of MLR did not show significantly decreased tibiotalar valgus tilt following SF. CLINICAL RELEVANCE: Residual valgus heel alignment after subtalar joint fusion in the surgical treatment of PCFD can lead to increased medial ligament strain. Although MLR might be considered for providing medial stability, it may not necessarily prevent the development of tibiotalar valgus tilt.

PURPOSE: The aim of our study was to determine the surgical outcomes of patients who underwent lateral femoral sliding osteotomy (LFSO) with total knee arthroplasty (TKA) for Ranawat's type 2 fixed valgus deformity. METHODS: The consecutive patients who underwent primary TKA with posterior-stabilized implant and LFSO for fixed valgus deformity were reviewed. The radiological parameters analyzed were pre- and postoperative hip-knee-ankle (HKA) angle and tibio-femoral angle in varus-valgus stress views. The clinical outcome was measured by Oxford knee score (OKS), knee society score (KSS), and functional score (KSS-F). The complications and any reoperation were noted in the follow-up. RESULTS: There were total 28 patients included with an average follow-up time of 47.2 ± 24.9 months. The average arc of motion was 101.3 ± 23.8° preoperatively and 102.7 ± 11.8° postoperatively (p > 0.05). The average deformity in varus and valgus stress views was 196.6 ± 4.8 and 207.8 ± 7.4°, respectively. There was significant improvement in HKA from 205.2 ± 8.3° preoperatively to 181.9 ± 3.7° postoperatively (p < 0.05). At the final follow-up, bony union of the osteotomy fragment was noted in all the patients. There was significant improvement in OKS, KSS, and KSS-F score from a preoperative 15.1 ± 3.9, 35.1 ± 10.6, and 26.6 ± 12.6 to 40.3 ± 2.9, 85.6 ± 4.8, and 89.4 ± 7.7, postoperatively (p < 0.05), respectively. One patient had acute periprosthetic joint infection that was managed with debridement and polyethylene insert exchange. CONCLUSION: Lateral femoral sliding osteotomy is an effective technique for optimal soft tissue balance in fixed valgus deformity. It provides satisfactory clinical outcome with restoration of knee alignment without using the constrained implants.

BACKGROUND:The displacement change parameters of the bone structure of the first metatarsal bone at the two-dimensional level of hallux valgus deformity are of great significance for clinical diagnosis and treatment,while the quantitative analysis of the three-dimensional deformity index may have some influences on the postoperative efficacy. OBJECTIVE:To explore the quantitative change of the three-dimensional deformity index of the first metatarsal bone after routine osteotomy and orthosis for hallux valgus deformity and to provide reference for clinical work. METHODS:100 patients with hallux valgus deformity(foot)in Hengshui People's Hospital from October 2020 to April 2023 were selected and all of them underwent conventional osteotomy and orthosis.Foot function was assessed by the American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale 6 months after surgery.Anterolateral X-rays of the foot in weight-bearing position and CT images in simulated weight-bearing position were taken before surgery and 6 months after surgery.The three-dimensional deformity indexes of the first metatarsal bone before and after surgery were quantitatively analyzed in patients with different ages,genders and therapeutic effects,including first-second intermetatarsal angle,hallux valgus angle,distal metatarsal articular angle,tibial sesamaid position,and first metatarsal rotation α angle.The value of the difference of three-dimensional deformity indexes of the first metatarsal bone before and after operation in evaluating the curative effect was analyzed. RESULTS AND CONCLUSION:(1)Six months after operation,the American Orthopedic Foot and Ankle Society score was 75-98(88.25±4.14)points,among which 56 cases were excellent,28 cases were good,14 cases were average,and 2 cases were poor.The excellent and good rate was 84%(84/100).(2)Compared with the preoperative results,first-second intermetatarsal angle,hallux valgus angle,distal metatarsal articular angle,tibial sesamaid position,and first metatarsal rotation α angle were significantly improved in patients of different ages and genders 6 months after surgery(P<0.05).First-second intermetatarsal angle,hallux valgus angle,distal metatarsal articular angle,tibial sesamaid position,and first metatarsal rotation α angle were all lower in patients with good curative effect 6 months after surgery than those with poor curative effect,and the difference before and after surgery was greater than those with poor curative effect(P<0.05).(3)The area under the curve of the difference evaluation of the first metatarsal three-dimensional deformity index before and after surgery was above 0.7,and the area under the curve of the combined evaluation of all indexes was the largest(0.902),which was significantly greater than the first metatarsal rotation α angle and distal metatarsal articular angle(P<0.05).(4)The quantitative analysis of the three-dimensional deformity index of the first metatarsal in patients with hallux valgus deformity is related to the postoperative effect,which has important guiding significance for improving the accuracy and comprehensiveness of preoperative evaluation and improving the treatment plan.
RESUMEN
Objective: To investigate the surgical technique and the short-term effectivenss of lateral unicompartmental knee arthroplasty (LUKA) through lateral approach in the treatment of valgus knee and to calculate the maximum value of the theoretical correction of knee valgus deformity. Methods: A retrospective analysis was performed on 16 patients (20 knees) who underwent LUKA and met the selection criteria between April 2021 and July 2022. There were 2 males and 14 females, aged 57-85 years (mean, 71.5 years). The disease duration ranged from 1 to 18 years, with an average of 11.9 years. Knee valgus was staged according to Ranawat classification, there were 6 knees of type â , 13 knees of type â ¡, and 1 knee of type â ¢. All patients were assigned the expected correction value of genu valgus deformity by preoperative planning, including the correction value of lateral approach, intra-articular correction value, and residual knee valgus deformity value. The actual postoperative corrected values of the above indicators were recorded and the theoretical maximum correctable knee valgus deformity values were extrapolated. The operation time, intraoperative blood loss, incision length, hospital stay, hip-knee-ankle angle (HKA), mechanical lateral distal femoral angle (mLDFA), mechanical medial proximal tibia angle (mMPTA), joint line convergence angle (JLCA), posterior tibial slope (PTS), range of motion (ROM), Hospital for Special Surgery (HSS) score, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score were also recorded for effectiveness evaluation. Results: The patients' incision length averaged 13.83 cm, operation time averaged 85.8 minutes, intraoperative blood loss averaged 74.9 mL, and hospital stay averaged 6.7 days. None of the patients suffered any significant intraoperative neurological or vascular injuries. All patients were followed up 10-27 months, with a mean of 17.9 months. One patient with bilateral knee valgus deformities had intra-articular infection in the left knee at 1 month after operation and the remaining patients had no complication such as prosthesis loosening, dislocation, and infection. The ROM, HSS score, and WOMAC score of knee joint significantly improved at each time point after operation when compared to those before operation, and the indicators further improved with time after operation, the differences were all significant ( P<0.05). Imaging measurement showed that HKA, mLDFA, JLCA, and PTS significantly improved at 3 days after operation ( P<0.05) except for mMPTA ( P>0.05). Postoperative evaluation of the knee valgus deformity correction values showed that the actual intra-articular correction values ranged from 0.54° to 10.97°, with a mean of 3.84°. The postoperative residual knee valgus deformity values ranged from 0.42° to 5.30°, with a mean of 3.59°. The actual correction values of lateral approach ranged from 0.21° to 12.73°, with a mean of 4.26°. Conclusion: LUKA through lateral approach for knee valgus deformity can achieve good early effectiveness. Preoperative planning can help surgeons rationally allocate the correction value of knee valgus deformity, provide corresponding treatment strategies, and the maximum theoretical correction value of knee valgus deformity can reach 25°.

INTRODUCTION: The modified 5-item frailty index (mFI-5) has been recently proposed as a useful tool for predicting postoperative complications in orthopedic surgery. We aimed to analyze the utility of this score in predicting complications and reoperations after hallux valgus (HV) deformity surgery. METHODS: 551 patients undergoing percutaneous HV corrective surgery were retrospectively reviewed. The mFI-5 was calculated based and patients were categorized in three groups: (1) non-frail: patients without any of the 5 comorbidities, (2) pre-frail: patients with one comorbidity and (3) frail: patients with two or more comorbidities. Complications and surgical reoperations were recorded. RESULTS: In the study period 772 percutaneous surgeries were performed to correct hallux valgus deformity, 551 patients were included with a median age of 60 (IQR 48-70). 389 patients were non-frail (70.6%), 132 were pre-frail (23.9%) and 30 were frail (5.4%). 75 patients suffered complications (13.6%). Even though the rate of complications was higher in frailty patients (23.3%) compared with pre-frail (13.6%) and non frail (12.8%), no significant differences were observed among groups. 48 patients required reoperation (8.7%) but the rate of reoperations among frailty groups was not significantly different (p=0.11). Frailty patients had worse AOFAS scores at final follow up (p=0.011). CONCLUSION: The mFI-5 was not useful to predict postoperative complications and reoperations after hallux valgus corrective surgery. Therefore, other factors should be considered when analyzing the risk of complications after HV corrective surgery.
RESUMEN
Valgus deformity of the ankle joint is a well-known and relatively common donor-site complication of free vascularized fibular graft harvest in children. Due to children having naturally greater ligamentous laxity than adults, the tibiofibular syndesmosis can be compromised with the loss of the fibular shaft, leading to valgus ankle deformity (VAD). Syndesmotic stabilization with screws is commonly recommended in subsets of pediatric patients at the greatest risk of this complication. In adults, the occurrence of VAD is seldom reported in the literature following fibular graft harvest. As such, no recommendation for syndesmotic stabilization exists in the adult population. We present a case of end-stage VAD in an adult patient with Ehlers-Danlos syndrome (EDS) following free vascularized fibular graft harvest. We hypothesize that other patients with generalized joint hypermobility may face the same complication and, thus, recommend the consideration of syndesmotic stabilization or primary syndesmotic fusion at the time of graft harvest in this patient population.
RESUMEN
We present a case of a patient who underwent a modified scarf osteotomy and tumour excision based on a preoperative diagnosis of hallux valgus deformity and accompanying bursitis. Subsequent histopathological examination revealed that the tumour was an angioleiomyoma. While tumours around the first metatarsophalangeal (MTP) joint are typically associated with gouty nodules, infections, or swollen bursa (bursitis) in patients with hallux valgus deformity, the occurrence of soft tissue tumours in this area is rare. Moreover, angioleiomyoma is an even rarer form of soft tissue tumour and is seldom suspected prior to resection. To our knowledge, there have been no reports of angioleiomyoma arising in the first MTP joint. However, it is important to consider the possibility of an atypical tumour in cases where soft tissue masses are present, even in patients with hallux valgus deformity, and to perform at least imaging tests such as ultrasound and magnetic resonance imaging before surgery. This prospect should always be kept in mind.

RESUMEN
PURPOSE: The objectives of this study were to evaluate functional results, revision-free survival, and the influence of postoperative alignment on outcomes after MCWHTO. METHODS: This retrospective study included 27 MCWHTO operated on from 2009 to 2021. Radiographic measurements were performed pre- and postoperatively. The HKA (Hip-Knee-Ankle angle), MPTA (Medial Proximal Tibial angle), LDFA (Lateral Distal Femoral Angle), JLO (Joint Line Obliquity), and JLCA (Joint Line Convergence Angle) were evaluated. The Knee injury and Osteoarthritis Outcome Score (KOOS), the International Knee Society (IKS) Function and Knee Score, and the Subjective Knee Value (SKV) as well as revision-free survival were evaluated. Postoperative alignment and its influence on clinical outcomes were also analysed. RESULTS: The mean follow-up was 61.9 months ± 31.4 (13-124). The HKA, MPTA, and JLCA angles were decreased post-operatively (respectively, Δ = 5.9° ± 2.6, p < 0.001; Δ = 6.1° ± 3.2, p < 0.001 and Δ = 2.5° ± 1.9, p < 0.001). LDFA and JLO were unchanged, post-operatively (respectively, Δ = 0.1° ± 2.2, p = 0.93 and Δ = 1.2° ± 3.3, p = 0.23). Postoperative HKA correlated with knee IKS (R = - 0.15, p = 0.04) and function IKS (R = - 0.44, p = 0.03). Postoperative LDFA correlated with knee IKS(R = 0.8, p < 0.01). Patients with postoperative HKA ≤ 180° had better KOOS (Δ = 12.3, p = 0.04) and IKS function (Δ = 28.1, p < 0.01) than those with HKA > 180°. CONCLUSION: Functional results and revision-free survival after MCWHTO are satisfactory when the deformity is located in the proximal tibia. The joint line obliquity is not significantly altered with small tibial correction and, obtaining an overall neutral or slightly varus alignment under the conditions of this study allowed an improvement in the postoperative clinical scores. The literature is still inconclusive on the ideal alignment for valgus deformities and larger series are needed to draw definitive conclusions. LEVEL OF EVIDENCE: IV, case series.
