Background: Different osteotomies have been proposed for the treatment of bunionette deformity. Minimally invasive surgery is now increasingly popular for a variety of forefoot conditions. The aim of this study was to evaluate the outcome following fifth minimally invasive distal metatarsal metaphyseal osteotomy (DMMO) for bunionette deformity. Methods: Nineteen patients (21 feet) who had symptomatic bunionette deformity and failed conservative treatment between 2014 and 2016 were included in this retrospective study. Clinical data were recorded, and pre- and postoperative Manchester-Oxford Foot Questionnaire (MOXFQ) scores and visual analog scale (VAS) pain score were collected. The mean follow-up was 28 months (range, 12-47). Results: The mean MOXFQ summary index score decreased from 71 (range, 59-81) preoperatively to 10 (range, 0-30) postoperatively. All 3 MOXFQ domains also improved. The average improvement in VAS score was 7. Forefoot swelling and some painful symptoms took an average of 3 months to settle. There were no wound or nerve complications. One patient required a dorsal cheilectomy for a symptomatic prominent dorsolateral callus formation. Conclusion: The minimally invasive fifth DMMO for bunionette deformity was a safe and effective technique. It had relatively few complications and led to good clinical results. We believe it is important to warn patients that the forefoot swelling will take months to settle compared to an osteotomy with fixation, and there is a 10% chance of a prominent callus over the osteotomy site. Level of Evidence: Level IV, retrospective case series.

Purpose The purpose of this study was to evaluate the effect of correction of abnormal radiographic parameters on postoperative pain in a group of patients treated arthroscopically for femoracetabular impingement (FAI). Methods A retrospective study was performed on 23 patients affected by mixed-type FAI and treated arthroscopically. There were 11 males and 12 females with a mean age of 46.5 (range: 28–67) years. Center-edge (CE) and α angles were measured on preoperative and postoperative radiographic and magnetic resonance imaging (MRI) studies and were correlated with persistent pain at follow-up. Results The mean preoperative CE and α angles were 38.6 ± 5.2 and 67.3 ± 7.2 degrees, respectively. At follow-up, in the 17 pain-free patients, the mean pre- and postoperative CE angle were 38.1 ± 5.6 and 32.6 ± 4.8 degrees, respectively, whereas the mean pre- and postoperative α angles at MRI were 66.3 ± 7.9 and 47.9 ± 8.9 degrees, respectively. In six patients with persistent hip pain, the mean pre- and postoperative CE angles were 39.8 ± 3.6 and 35.8 ± 3.1 degrees, respectively, whereas the mean pre- and postoperative α angles were 70.0 ± 3.9 and 58.8 ± 2.6 degrees, respectively. Mean values of all the analyzed radiological parameters, except CE angle in patients with pain, improved significantly after surgery. On comparing patient groups, significantly lower postoperative α angles and lower CE angle were observed in patients without pain. Conclusion In case of persistent pain after arthroscopic treatment of FAI, a new set of imaging studies must be performed because pain may be related to an insufficient correction of preoperative radiographic abnormalities. Level of Evidence Level IV, retrospective case series.

Valgus Instability

Background: During high tibial osteotomy (HTO), the superficial medial collateral ligament (sMCL) is cut or released at any degree to expose the osteotomy site and achieve the targeted alignment correction according to the surgeon’s preference. However, it is still unclear whether transection of sMCL increases valgus laxity. Purpose: We aimed to assess the outcomes and safety of sMCL transection, especially focusing on iatrogenic valgus instability. Study Design: Case series; Level of evidence, 4. Methods: Seventy-two patients (89 knees) who underwent medial open wedge HTO (MOWHTO) with transection of the sMCL between October 2013 and September 2018 were retrospectively investigated. Clinical evaluations, including the International Knee Documentation Committee (IKDC) score, Knee injury and Osteoarthritis Outcome Score (KOOS), and Tegner and Lysholm scores, were performed preoperatively and at 2 years postoperatively. The radiographic parameters hip-knee-ankle (HKA) angle, joint line convergence angle on standing radiographs (standing JLCA), and weightbearing line (WBL) ratio were assessed preoperatively and at 3 months, 6 months, 1 year, and 2 years postoperatively. To evaluate valgus laxity, we assessed the valgus JLCA and medial joint opening (MJO) at the aforementioned time points using valgus stress radiographs. Results: All clinical results at the 2-year follow-up were significantly improved compared with those obtained at the preoperative assessment ( P < .001). The postoperative HKA angle significantly differed from the preoperative one, and no significant valgus progression was observed during follow-up (preoperative, 8.5°± 2.7°; 3 months, –3.5°± 2.0°; 6 months, –3.2°± 2.3°; 1 year, –3.1°± 2.3°; 2 years, –2.9°± 2.5°; P < .001) The mean WBL ratio was 62.5% ± 9.0% at 2 years postoperatively. The postoperative valgus JLCA at all follow-up points did not significantly change compared with the preoperative valgus JLCA (preoperative, –0.1°± 2.1°; 3 months, –0.2°± 2.4°; 6 months, –0.1°± 2.5°; 1 year, 0.1°± 2.5°; 2 years, 0.2°± 2.2°) The postoperative MJO at all follow-up points did not significantly change compared with the preoperative MJO (preoperative, 7.1 ± 1.7 mm; 3 months, 7.0 ± 1.7 mm; 6 months, 6.9 ± 1.9 mm; 1 year, 6.7 ± 1.8 mm; 2 years, 6.8 ± 1.8 mm). Conclusion: Transection of the sMCL during MOWHTO does not increase valgus laxity and could yield desirable clinical and radiographic results.

Background: The Salto Talaris is a fixed-bearing implant first approved in the US in 2006. While early surgical outcomes have been promising, mid- to long-term survivorship data are limited. The aim of this study was to present the survivorship and causes of failure of the Salto Talaris implant, with functional and radiographic outcomes. Methods: Eighty-seven prospectively followed patients who underwent total ankle arthroplasty with the Salto Talaris between 2007 and 2015 at our institution were retrospectively identified. Of these, 82 patients (85 ankles) had a minimum follow-up of 5 (mean, 7.1; range, 5-12) years. The mean age was 63.5 (range, 42-82) years and the mean body mass index was 28.1 (range, 17.9-41.2) kg/m2. Survivorship was determined by incidence of revision, defined as removal/exchange of a metal component. Preoperative, immediate, and minimum 5-year postoperative AP and lateral weightbearing radiographs were reviewed; tibiotalar alignment (TTA) and the medial distal tibial angle (MDTA) were measured to assess coronal talar and tibial alignment, respectively. The sagittal tibial angle (STA) was measured; the talar inclination angle (TIA) was measured to evaluate for radiographic subsidence of the implant, defined as a change in TIA of 5 degrees or more from the immediately to the latest postoperative lateral radiograph. The locations of periprosthetic cysts were documented. Preoperative and minimum 5-year postoperative Foot and Ankle Outcome Score (FAOS) subscales were compared. Results: Survivorship was 97.6% with 2 revisions. One patient underwent tibial and talar component revision for varus malalignment of the ankle; another underwent talar component revision for aseptic loosening and subsidence. The rate of other reoperations was 21.2% ( n = 18), with the main reoperation being exostectomy with debridement for ankle impingement ( n = 12). At final follow-up, the average TTA improved 4.4 (± 3.8) degrees, the average MDTA improved 3.4 (± 2.6) degrees, and the average STA improved 5.3 (± 4.5) degrees. Periprosthetic cysts were observed in 18 patients, and there was no radiographic subsidence. All FAOS subscales demonstrated significant improvement at final follow-up. Conclusions: We found the Salto Talaris implant to be durable, consistent with previous studies of shorter follow-up lengths. We observed significant improvement in radiographic alignment as well as patient-reported clinical outcomes at a minimum 5-year follow-up. Level of Evidence: Level IV, retrospective case series.

Purpose: To investigate the clinical outcomes of Visian implantable collamer lens (ICL) implantation according to lens size and implantation angle. Setting: Onnuri Smile Eye Clinic, Seoul, Republic of Korea. Design: Retrospective case series. Methods: This study included 566 eyes of 283 patients treated with ICL implantation. Patients were divided into three groups: horizontally implanted same-sized ICL (group A), horizontally implanted different sized-ICL (group B: large ICL and small ICL) and same sized-ICL implanted with a different implantation angle (group C: horizontal and vertical). Results: At 12-month follow-up, the mean vault was 0.78 ± 17, 0.48 ± 0.13, 0.71 ± 0.18 and 0.44 ± 0.16 mm when large and small sized ICL was used in group B ( p < 0.001), and when ICL was horizontally and vertically implanted in group C ( p = 0.021), respectively. And the mean SE was −0.11 ± 0.30, −0.34 ± 0.42, −0.3 ± 0.56 and −0.64 ± 0.66 dioptres (D), when the large and the small sized ICL was used group B ( p = 0.039), and when the ICL was horizontally and vertically implanted in group C ( p = 0.036), respectively. No significant difference in UDVA, IOP and ECD between both eyes in groups B and C was observed. No statistical difference was found in the vault between both eyes for groups B and C. Conclusions: The vault was significantly higher and the SE was significantly more hyperopic when a larger-sized ICL was used or the ICL was horizontally implanted compared to when the ICL was vertically implanted.

Background: Few studies have reported midterm outcomes after single-stage flexor digitorum longus (FDL) tendon transfer to the lateral foot for irreparable rupture of the peroneal tendons. Methods: Over a 7-year period (2008-2015), 25 consecutive patients underwent transfer of the FDL to the fifth metatarsal for irreparable peroneal tendon tears. Of these, 15 patients were available for inclusion with a mean follow-up of 53.7 ± 23.3 months, mean age at surgery of 48.4 years, and mean body mass index (BMI) of 29.8 kg/m2. Patients completed the pain visual analog scale (VAS), Foot Function Index (FFI), Short Musculoskeletal Function Assessment (SMFA), and Foot and Ankle Ability Measure (FAAM) and participated in range of motion, peak force, and peak power testing. Results: All 15 patients were satisfied with their surgery and reported a reduction in their pain level with a decreased VAS of 5.6 ± 2.5. The mean FFI was 12.8 ± 9.2, the SMFA Function Index was 12.4 ± 8, and the mean SMFA Bothersome Index was 11.5 ± 11. The mean FAAM was 86.4 ± 9.7. Patients had on average 58% less eversion and 28% less inversion compared with the nonoperative side. Isometric peak torque and isotonic peak velocity were 38.4% and 28.8% less compared with the contralateral side, respectively. The average power in the operative limb was diminished by 56% compared with the nonoperative limb. Conclusion: In this small case series with midterm follow-up, FDL transfer to the lateral foot for significant, irreparable peroneal tendinopathy was an effective and durable treatment option. Level of Evidence: Level IV, retrospective case series.

Abstract Background This study aimed to investigate the efficacy of percutaneous hemiepiphysiodesis for gradual correction of symptomatic juvenile hallux valgus (HV) deformity. Methods Between 2012 to 2014, 24 patients with symptomatic juvenile HV were treated by combined percutaneous medial drilling hemiepiphysiodesis of the first proximal phalanx and lateral transphyseal screw hemiepiphysiodesis of the first metatarsal at our institution. Twenty-one of 24 patients fulfilled inclusion criteria had a complete radiological and clinical follow-up of at least 2 years. Preoperative and postoperative radiographs of the feet were reviewed for measurements of hallux valgus angle (HVA), intermetatarsal angle (IMA), proximal metatarsal articular angle (PMAA), proximal phalangeal articular angle (PPAA), and metatarsal length ratio (MTLR). Clinical outcomes were assessed using the AOFAS hallux metatarsophalangeal-interphalangeal score. Results The study included 21 consecutive patients (37 ft) for analysis. The mean age at surgery was 12.0 years (SD = 1.3) and mean follow-up after surgery was 35.1 months (SD = 6.0). With the data available, the HV deformity improved in terms of the reduction of HVA by a mean of 4.7 degrees (P < .001) and the reduction of IMA by 2.2 degrees (P < .001). The PMAA and PPAA also improved significantly in the anteroposterior plane; however, the PMAA difference was insignificant in lateral plane as expected. The mean difference in the MTLR was 0.00 (P = .216) which was indicative of no length discrepancy between first and second metatarsals. The AOFAS score increased from 68.7 to 85.2 (P < .001). In correlation analysis, time to physeal closure was significantly correlated with the final HVA change (r = −.611, P = .003). Conclusion Although combined hemiepiphysiodesis does not create a large degree of correction as osteotomy, yet it did improve HV deformity with adequate growth remaining in our series. It is a procedure that can be of benefit to patients with symptomatic juvenile HV from this minimal operative approach before skeletal maturity. Level of evidence Level IV, retrospective case series.

Background: Equinovalgus deformity is the second most common deformity in cerebral palsy and may be flexible or rigid. Several operative methods from joint sparing to arthrodesis have been described with varying success rates. The aim of this study was to investigate the effectiveness of naviculectomy in combination with midfoot arthrodesis (talo-cuneiform and calcaneocuboid arthrodesis) in the correction of a rigid equinovalgus foot deformity in cerebral palsy. Methods: Forty-eight rigid equinovalgus feet were operated upon in 30 patients from 2008 to 2013. Of these, 44 feet in 26 patients with cerebral palsy (Gross Motor Function Classification System III, IV, or V) with follow-up of more than 2 years were included in the study. The mean age at surgery was 18.1 years. The outcomes were measured objectively using radiographic angles and subjectively using 5 questions to be answered by the caregiver. The feet were then graded into excellent, good, fair, and poor. The mean follow-up was 5.0 ± 1.7 years. Results: Excellent to good results were obtained in 81% of the feet. Both objective and subjective outcomes improved significantly postoperatively ( P < .001). Three feet in 2 patients were graded as poor and underwent a revision operation for pain and recurrence. Conclusions: Naviculectomy in combination with midfoot arthrodesis enabled a good 3-dimensional correction of the forefoot. However, the procedure did not necessarily correct the fixed subtalar joint deformity. Several additional bony and soft-tissue procedures were necessary to achieve a complete correction in these difficult feet. Level of Evidence: Level IV, retrospective case series.

Background: Talar head fractures account for 2.6% to 10% of all talar fractures and are often associated with concomitant musculoskeletal injuries. The current literature only describes a total of 14 patients with talar head fractures and, with that, guidelines for management are lacking. The aim of the current study was to evaluate the management and long-term outcome of patients who have hindfoot trauma with concomitant talar head fractures. Methods: This study includes a retrospective cohort of patients with talar head fractures. Patient characteristics, trauma mechanism, fracture characteristics, treatment, follow-up, and complications were reported. Functional outcome was assessed using the Foot Function Index (FFI) and the American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score. Quality of life was measured by the EuroQol-5D (EQ-5D). Twenty-one patients with acute fractures of the talar head were identified. The mean follow-up time was 4.9 years. Results: All patients sustained additional ipsilateral foot and/or ankle injuries. Fifteen patients had operative management of their talar head fracture. There were no postoperative wound infections and no cases of avascular necrosis. All fractures united, and 29% of patients developed posttraumatic osteoarthritis. The overall mean FFI score index was 34.2, and the mean AOFAS score was 70.7. The mean EQ-5D index score was 0.74. Conclusion: Talar head fractures always coincided with other (foot) fractures. Management and long-term functional outcome were affected by the extent of associated injuries. Due to the low incidence and high complexity of talar head fractures, early referral to dedicated foot surgeons and centralization of complex foot surgery is recommended. Level of Evidence: Level IV, retrospective case series.

Morton's Neuroma

Background: Morton’s neuroma is a frequent cause of metatarsalgia. Operative treatment is indicated if nonoperative management has failed. The objective of the present study was to describe a technique of Morton’s neuroma excision by a minimally invasive commissural approach and evaluate the long-term outcome and complications. Methods: A retrospective study of 108 patients with Morton’s neuroma treated surgically with a commissural approach between September 1990 and December 2010 was performed. The surgical technique is described. Clinical outcomes and complications were evaluated. The average follow-up was 121 months. Eleven patients were men and 97 women. The average age was 49.4 years; 56.8% neuromas were at the third space and 43.2% at the second space. Six patients presented 2 neuromas in the same foot, and 9 patients had bilateral neuroma. Results: The visual analog scale (VAS) average pain score was 5.4 points preoperatively and 0.2 points at the final follow-up. The author found a significant difference between the VAS scores preoperatively and postoperatively ( P < .01). Excellent and good satisfaction outcomes were achieved in 93.6%. The postoperative complication incidence was 3%. Conclusion: The author believes a minimally invasive commissural approach has advantages over a dorsal or plantar incision. It is a simple and reproducible technique, with satisfactory outcomes, low complication rates, and a quick return to usual activities. Level of Evidence: Level IV, retrospective case series.

Background: Few studies have reported the outcomes following minimally invasive medial displacement calcaneal osteotomy (MDCO) for correction of pes planovalgus deformities. Methods: Charts were retrospectively reviewed for consecutive patients who underwent minimally invasive MDCO procedures by a single surgeon from 2013 to 2019 with more than 3 months of follow-up. A total of 160 consecutive patients who underwent 189 minimally invasive MDCO procedures were included in the study. Median follow-up was 12 months (interquartile range, 7-25 months). Results: Osteotomy healing complications were present in 7% of cases during the 6-year study period. A 12-month case cluster of osteotomy healing complications was observed. Healing complication rates were 28% during the cluster and 0.7% outside of the cluster. No definitive cause was found for the case cluster, although heat osteonecrosis from the burr was suspected to be involved. Osteotomy healing complications were significantly associated with higher American Society of Anesthesiologists (ASA) classification, female sex, current tobacco use, and higher body mass index (BMI). Healing complications were not associated with osteotomy technique or fixation type. Other complications included wound dehiscence (3%), surgical site infection (2%), transient nerve symptoms (6%), and persistent nerve symptoms (2%). Nerve symptoms were significantly associated with an increased number of concomitant procedures. Conclusion: Patients with higher ASA classification, current tobacco use, and higher BMI were at higher risk for osteotomy healing complications after minimally invasive MDCO procedures. Patients were also more likely to develop nerve complications with more extensive surgical procedures. Level of Evidence: Level IV, retrospective case series.
