Shibuya N, Jupiter DC. Effectiveness of Concurrent Ankle Arthroscopy During Open Reduction and Internal Fixation of Malleolar Fractures in Prevention of Common Short-Term Complications. J Foot Ankle Surg 2024; 63:473-476. [PMID: 38438101 DOI: 10.1053/j.jfas.2024.02.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 02/04/2024] [Accepted: 02/09/2024] [Indexed: 03/06/2024]
Abstract
Rotational malleolar fractures result in a high prevalence of intra-articular pathologies; therefore, routine arthroscopic assessment may be beneficial in the surgical treatment of ankle fractures. However, the clinical studies regarding the effectiveness of arthroscopy thus far have mixed results. We investigated the efficacy of concurrent arthroscopy during the treatment of malleolar fractures using a large U.S. healthcare data set. Those who had arthroscopy were compared with those who did not, during the surgical treatment of malleolar fractures, while adjusting for covariates of clinical relevance. The analysis showed that concurrent arthroscopy is protective against postoperative repeat surgery (OR = 0.13, 95CI = 0.02-0.41) and wound dehiscence (OR = 0.18, 95CI = 0.03-0.56). The number of added arthroscopy cases needed to avoid one repeat surgery was 74, while that of wound dehiscence was 52. Further studies are needed to determine if routine use of arthroscopy is justifiable in the surgical treatment of malleolar fractures, given the additional costs and time to the healthcare system.

Foot Ankle Surg 2024; 30:309-312. [PMID: 38302327 DOI: 10.1016/j.fas.2024.01.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 12/13/2023] [Accepted: 01/05/2024] [Indexed: 02/03/2024]
Abstract
INTRODUCTION Ankle fractures rank as the second most common lower limb fractures, and surgical intervention is essential for unstable ankle fractures. The use of ankle arthroscopy in such cases offers several advantages. This study aim is to assess whether arthroscopy influenced on complication rates in 171 ankle fractures treated with arthroscopic assistance. METHODS This retrospective epidemiological analysis encompassed adult ankle fractures between December 2018 and December 2021. Initially, 173 patients were considered, but two were excluded, leaving a final sample of 171 patients. Postoperative complications were categorized as major or minor. RESULTS The study included 171 patients with surgically treated ankle fractures assisted by arthroscopy, comprising 76 females and 95 males, with an average age of 41.9 years. Syndesmosis injuries were treated in all diagnosed cases (55.0%), and deltoid ligament injuries received attention when identified (33.7%). Arthroscopic techniques were preferred over open techniques (47.4%). Ten patients experienced complications, consisting of 2 major and 8 minor complications (5.8%). DISCUSSION Our study's epidemiological findings align with prior literature, demonstrating that intra-articular injuries accompany 63% to 79% of ankle fractures. Arthroscopy allows for both diagnosis and treatment within the same procedure, including joint lavage to reduce inflammation. We diagnosed 57 deltoid injuries and identified a statistical relationship between chondral, syndesmotic, and deltoid ligament injuries. Infection is a common complication in ankle fracture surgery, with rates ranging from 1.44% to 16%. Our study yielded a 5.8% complication rate, comprising 1.2% major and 4.6% minor complications. Patients undergoing ORIF with arthroscopic assistance had a lower prevalence of infection. CONCLUSION The use of arthroscopic assistance in the surgical treatment of ankle fractures does not increase the overall complication rate. LEVEL OF EVIDENCE IV.

Abstract
Purpose To evaluate graduating orthopaedic resident case volume and variability for ankle arthroscopy from 2016 to 2020. Methods The Accreditation Council for Graduate Medical Education surgical case log data from 2016 to 2020 for graduating United States orthopaedic surgery residents was assessed. Arthroscopy procedures of the leg/ankle were categorized. The average number of cases performed per resident was compared from 2016 to 2020 to determine the percent change in case volume. The 10th, 30th, 50th, 70th, and 90th percentiles of case volumes from 2016 to 2020 were presented to demonstrate case volume variability. Results There was no significant change in the average number of leg/ankle arthroscopy cases from 2016 to 2020 (6.2 ± 5 [range 0-35] vs 6.1 ± 6 [range 0-76] P = .732), despite a 19% increase in the average number of total leg/ankle procedures performed over time (168.4 ± 47 [range 55-414] in 2016; 200.8 ± 57 in 2020 [range 67-601], P < .001). There was wide variability in ankle arthroscopy case volume among residents. The 90th percentile of residents performed 13 cases in 2020, compared with 5 in 50th percentile, and 1 in the 10th percentile. Conclusions Orthopaedic surgery resident exposure to ankle arthroscopy has remained low and highly variable overtime, despite an overall increase in the total number of leg/ankle procedures performed. Clinical Relevance Understanding ankle arthroscopy in case volume and variability is important for programs to ensure that orthopaedic residents are gaining adequate exposure to increasingly popular procedures. Orthopaedic surgery residency programs should explore methods to increase resident exposure to ankle arthroscopy.

Orthop J Sports Med 2022; 10:23259671211066856. [PMID: 35024369 PMCID: PMC8743951 DOI: 10.1177/23259671211066856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Accepted: 09/27/2021] [Indexed: 11/29/2022] Open
Abstract
Background: Despite appropriate care, a subset of patients with ankle fractures has persistent pain. This condition may be associated with intra-articular pathology, which is present up to 65% of the time. Purpose: To quantify how much of the talus is visible through an open approach to a standard supination external rotation bimalleolar ankle fracture as a percentage of the entire weightbearing surface of the talus. Study Design: Descriptive laboratory study. Methods: Standard ankle approaches to lateral and medial malleolar fractures were performed in 4 cadaveric ankles from 2 cadavers. Osteotomies were made to simulate a supination external rotation bimalleolar ankle fracture based on the Lauge-Hansen classification. The visible segments of talar cartilage were removed. The tali were then exhumed, and the entire weightbearing superior portion of the talus was assessed and compared with the amount of cartilage removed by an open approach. The mean of the data points as well as the 95% confidence interval were calculated. Results: Four ankle specimens from 2 cadavers were used for these measurements. The mean surface area of the talus was 14.0 cm2 (95% CI, 13.3-14.7 cm2), while the mean area visible via an open approach was 2.1 cm2 (95% CI, 0.5-3.6 cm2). The mean proportion of the talus visualized via an open approach was 14.8% (95% CI, 3.6-26.1%). Conclusion: These findings indicate that the true area of weightbearing talar surface visible during an open exposure may be less than what many surgeons postulate. Clinical Relevance: Only a small fracture of the talus is visible via an open approach to the talus during fracture fixation. This could warrant arthroscopic evaluation of these injuries to evaluate and treat osteocondral lesions resulting from ankle fractures.

Abstract
OBJECTIVE To determine the role of magnetic resonance imaging (MRI) MOCART (Magnetic Resonance Observation of Cartilage Repair Tissue) 1 and 2.0 scores in the assessment of postoperative outcome after autologous matrix-induced chondrogenesis (AMIC) for the treatment of osteochondral lesions of the talus (OLTs). It was hypothesized that preoperative patient factors or OLT morphology are associated with postoperative MOCART scores; yet postoperative clinical outcome is not. STUDY DESIGN Cohort study; Level of evidence, 4. This study evaluated isolated AMIC that were implanted on the talus of 35 patients for the treatment of symptomatic OLT. Tegner and AOFAS (American Orthopaedic Foot and Ankle Society) scores were obtained at an average follow-up of 4.5 ± 1.8 years and postoperative MRI scored according to the MOCART 1 and 2.0. RESULTS OLT size showed significant correlation with postoperative MRI scores (MOCART 1: P = 0.006; MOCART 2.0: P = 0.004). Bone grafting was significantly associated with a MOCART 1 subscale (signal intensity of repair tissue; P = 0.038). Age and defect size showed significant correlations with MOCART 2.0 subscales (P < 0.05). Patients with shorter follow-up had a significantly higher MOCART 1 score and a trend toward better MOCART 2.0 scores than patients with longer follow-up (64.7 vs. 52.9 months, P = 0.02; 69.4 vs. 60.6 months, P = 0.058). No MOCART score was associated with postoperative patient-reported outcomes (n.s.). CONCLUSION Osteochondral lesion size is associated with postoperative MOCART scores in patients treated with AMIC for OLTs, with decreasing MOCART scores over time. Yet clinical outcome does not correlate with any MOCART score. Thus, MOCART assessment seems to have no significant role in the postoperative treatment of asymptomatic patients that underwent AMIC for OLTs.

Abstract
BACKGROUND Ankle fractures are one of the most common injuries managed by orthopedic surgeons. Although the etiology of posttraumatic osteoarthritis in anatomically reduced ankle fractures is not completely known, several studies suggest that undetected intra-articular pathology at the time of injury may play a role. The purpose of this study is to report the operative findings of ankle arthroscopy as an adjunct to ankle fracture open reduction and internal fixation. METHODS A retrospective review was performed of all ankle fractures treated consecutively at our institution by a single surgeon from August 2010 to October 2019, which were found using Current Procedural Terminology codes. A total of 84 patients met our inclusion criteria for whom patient demographics and clinical history were collected. Pre- and postoperative diagnoses from every operative report were noted as well as intra-articular intervention made during the time of arthroscopy. RESULTS The study included 49 men (58.3%) and 35 women (41.7%), with a mean age of 39.0 (range, 12-69; SD = 15.0) years. Sixty-three patients (75%) had new diagnoses detected by the addition of ankle arthroscopy. The most common new pathology seen arthroscopically were osteochondral lesions (n = 36, 41.9%) and posterior malleolus fractures (n = 28, 32.6%). Thirty-four patients had a total of 40 additional arthroscopic procedures in conjunction with their fracture management. Complications were noted in 13 patients, with hardware removal (n = 8) being the most common (62%). CONCLUSION Ankle arthroscopy can act as a significant diagnostic and prognostic tool and can help address intra-articular injuries without adding considerable cost or serious adverse events.

Abstract
BACKGROUND The deep deltoid ligament (DDL) is a key stabilizer to the medial ankle and ankle mortise and can be disrupted in ligamentous supination external rotation type IV (LSER4) ankle fractures. The purpose of this study was to define the medial clear space (MCS) measurement on injury mortise radiographs that corresponds with complete DDL injury. METHODS A retrospective record review at a level 1 hospital was performed identifying patients with LSER4 ankle fractures who underwent arthroscopy and open reduction internal fixation. Chart reviews provided arthroscopic images and operative reports. Complete DDL injury was defined as arthroscopic visualization of the posterior tibial tendon (PTT). Inability to completely visualize the PTT was defined as a partial DDL injury. MCS was measured on injury mortise radiographs. Eighteen subjects met inclusion criteria. RESULTS Twelve subjects had complete and 6 subjects had partial DDL injury based on arthroscopic findings. Patients with complete DDL injury and those with partial DDL injury had injury radiograph MCS ranging from 5.5 to 29.9 mm and 4.0 to 5.0 mm, respectively. All patients with MCS ≥5.5 mm on injury radiographs had complete DDL injury and all patients with MCS ≤5.0 mm on injury radiographs had partial DDL injury. CONCLUSION Complete DDL injury was found on injury ankle mortise radiographs as MCS widening of ≥5.5 mm, which correlated with arthroscopic visualization of the PTT. Using this cutoff, surgeons can surmise the presence of a complete deltoid ligament injury, allowing for improved preoperative planning. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Operative costs associated with arthroscopic assisted open reduction and internal fixation of acute ankle fractures. Foot (Edinb) 2021; 46:101765.

Abstract
BACKGROUND Ankle fractures are a common orthopedic injury that frequently involves associated cartilage lesions, soft tissue damage, and a significant inflammatory burden. Despite studies revealing intra-articular pathology in up to 79% of ankle fractures, only 1% of open reduction and internal fixation (ORIF) procedures undergo arthroscopic evaluation. The primary purpose of this study was to determine the cost effectiveness of ankle arthroscopy performed at time of ORIF for ankle fracture. METHODS An IRB approved retrospective review of patients who sustained ankle fractures and underwent ORIF with and without concomitant arthroscopic surgery between 2015 and 2020 were investigated. Patient demographics, fracture characteristics, outcomes, and cost data were collected and analyzed. RESULTS There were 567 total ORIF and 28 ORIF and scope included for cost analysis purposes. Total surgical costs averaged $6,537.62 and $6,886.46 for the ORIF only and ORIF and scope procedures respectively. Total direct costs, including operating room time, for the same procedures were found to average $6,212.34 and $7,312.10 for the ORIF only and ORIF and scope procedures respectively. The cost difference between the ORIF only and with arthroscopy was not statistically significant (p = 0.1174). Twelve of the 28 arthroscopic patients (42.86%) had grade 3 or full thickness chondral lesions, and 11/28 (39.28%) arthroscopic patients were found to have grade 1-2 cartilage changes. CONCLUSION In the acute treatment of ankle fractures, concurrent arthroscopic evaluation does not add a significant cost to the procedure and may result in improved short and long term benefits for the patient. With improved arthroscopic efficiency, the cost differential can be further reduced. LOE: IV.

Abstract
Although there is growing evidence supporting posterior-based surgical approaches to open reduction internal fixation (ORIF) of malleolar fractures, the lateral approach still remains the standard of care for this injury. The purpose of this review was to integrate the results of several studies investigating outcomes following posterior-based approaches to the ORIF of malleolar fractures. The literature search was undertaken using PubMed, the Cochrane Library, and Embase. Crude event rates for fracture healing and postoperative complications were calculated. When possible, meta-analyses were conducted to estimate the relative risk of these outcomes between patients treated by posterior-based approaches versus other approaches to ORIF of malleolar fractures. Twenty-two studies were eligible, and 4 studies were included in the meta-analyses. The healing rate was 100% in all patients, regardless of the surgical approach. Overall, 1.26% of patients developed an infection, 0.63% required reoperation, 1.13% experienced aseptic loosening, 5.53% experienced pain after treatment, and 2.52% experienced symptomatic hardware. No malunion or heterotopic ossification was reported in any study. Among patients treated with a posterior-based approach, the most frequently reported complication was infection (2.50%), with lower rates of reoperation and postoperative pain. Patients with trimalleolar fractures experienced slightly poorer outcomes. Patients treated by posterior-based approaches had a significantly increased risk of infection (p = .010) relative to those treated by the lateral approach; patients treated by the lateral approach had a significantly increased risk of pain after surgery (p = .004) and symptomatic hardware (p = .007). This study brought together evidence that posterior-based surgical approaches and non-posterior-based approaches to ORIF are effective in healing malleolar fractures, with significant differences in specific postoperative complications that need to be further explored.

Abstract
Especially after complex ankle fractures, patients regularly suffer from residual symptoms, presumably due to occult intra-articular injuries. The aim of this study was to evaluate the intra-articular lesions, identify fractures specifically at risk for these, and assess the results after arthroscopically assisted open reduction and internal fixation of complex ankle fractures after 1 year. The primary outcome was the American Orthopedic Foot and Ankle Society (AOFAS) hindfoot score. Secondary outcome parameters were the Olerud and Molander Ankle Score (OMAS), Tegner activity scale, arthroscopic findings, functional assessment, and complications. Thirty-two patients (56% female) were enrolled. Chondral lesions were detected in 91%. Full-thickness lesions treated by microfracturing were observed in 0% of unimalleolar, 43% of bimalleolar, and 40% of trimalleolar fractures. After 1 year, the median (interquartile range) AOFAS was 94 (9) and OMAS was 90 (10) for all patients. When analyzing factors possibly influencing the outcome, age, sex, smoking, grading for surgical procedures according to the American Society of Anesthesiologists, fracture type (uni-, bi-, or trimalleolar), severity of chondral lesions graded according to the International Cartilage Repair Society (grade <4 versus grade 4), and syndesmotic instability had no significant influence on the outcome. The only variable significantly influencing the AOFAS (p = .004) and OMAS (p < .001) was body mass index (BMI; rs = -0.522 and -0.606, respectively), with a higher BMI resulting in inferior outcome scores. Complications were observed in 3 patients, 2 with superficial skin necrosis at the posterolateral incision and 1 nonunion of the medial malleolus. Taken together, these data show that intra-articular injuries were common in ankle fractures. Bi- and trimalleolar fractures were particularly at risk for full-thickness lesions. A higher BMI tended to result in inferior outcome scores. Arthroscopically assisted open reduction and internal fixation led to good to excellent results in all but 1 patient.

[PMID: 32057988 DOI: 10.1016/j.arthro.2020.01.053] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2019] [Revised: 01/19/2020] [Accepted: 01/20/2020] [Indexed: 02/02/2023]
Abstract
PURPOSE To evaluate the feasibility of arthroscopic reduction percutaneous fixation (ARPF) in the treatment of isolated medial malleolar fracture and compare the results with those of conventional open reduction internal fixation (ORIF). METHODS This prospective study enrolled 77 patients with isolated medial malleolar fracture between November 2011 and February 2016. The patients were assigned to the ARPF (n = 34) and ORIF (n = 43) groups. The Olerud-Molander ankle score (OMAS), ankle range of motion (ROM), visual analog scale, and radiographic evaluation were determined at the scheduled follow-up. RESULTS In the ARPF group, 11 of 34 patients (32.4%) had chondral lesions. Tears of the deltoid ligament and anterior inferior tibiofibular ligament were noted in 3 (8.8%) and 15 (44.1%) patients, respectively. The mean follow-up was 5 years. The mean OMAS was higher in the ARPF group than in the ORIF group. The differences were statistically significant at 6 months (mean ± standard deviation, 80.2 ± 4.0 for ARPF vs 77.2 ± 4.1 for ORIF, P = .005) and 1 year (92.9 ± 4.9 vs 88.1 ± 4.6, P < .001), but not at the latest follow-up (P = .081). Ankle ROM was markedly improved in the ARPF group, unlike in the ORIF group at 6 months (dorsiflexion, P = .025; plantarflexion, P < .001) and 1 year (dorsiflexion and plantarflexion, P < .001). The improvement remained at the latest follow-up in plantarflexion (P = .001) but not in dorsiflexion (P = .354). CONCLUSIONS Arthroscopy-assisted reduction is a feasible alternative modality with superior short-term outcomes for treating isolated medial malleolar fracture, but its superiority may be attenuated in the intermediate term. LEVEL OF EVIDENCE Level III, comparative study.

Abstract
OBJECTIVE To develop a new type of internal fixation device which can be used to treat the minor avulsion fracture of the medial malleolus, lateral malleolus, the base of the fifth metatarsal, and the ulnar styloid process, and investigate the reliability and effectiveness of the device through biomechanical test. METHODS Eighty human's bone specimens with complete medial malleolus, lateral malleolus, the base of the fifth metatarsal, and the ulnar styloid process were selected and measured the anatomic indexes (the height, width, and thickness of medial malleolus, lateral malleolus, the base of the fifth metatarsal, and the ulnar styloid process). The CT three-dimensional reconstruction data of 200 healthy adults which including medial malleolus, lateral malleolus, the base of the fifth metatarsal, and the ulnar styloid process was also selected and measured the anatomic indexes by Mimics software. The plastic rod-hook plate was designed according to the measured results and prepared. Forty fresh porcine lower limb specimens were randomly divided into groups A and B (20 in each group), and 8 adult lower limb specimens including 4 left and 4 right were also randomly divided into groups A and B (4 in each group). All specimens were prepared for avulsion fracture of medial malleolus. Then, the fractures were fixed with plastic rod-hook plate in group A and wire anchor in group B. The load and axial torsion test of ankle joint were carried out by universal biomechanical testing machine. RESULTS According to the anatomical characteristics, a plastic rod-hook plate was designed successfully. The biomechanical test results between animal and human specimens were consistent. There was a linear relationship between load and displacement in the ankle distal load test. The displacement when loaded to the maximum load was significantly lower in group A than in group B ( P<0.05). The torsion angle and torque were significantly higher in group A than in group B when the internal fixation failed in the axial torsion test of the ankle joint ( P<0.05), and the torsion angle was significantly smaller in group A than in group B when the torque was 1 N·m ( P<0.05), and the maximum torque was also significantly higher in group A than in group B ( P<0.05). However, there was no significant difference in torsion angle between the two groups in the maximum torque ( P>0.05). CONCLUSION The biomechanical properties of plastic rod-hook plate is obviously better than wire anchor, and the fixation of avulsion fracture with plastic rod-hook plate is easy to operate, which is expected to be used in the clinical treatment of minor avulsion fractures such as medial malleolus, lateral malleolus, base of the fifth metatarsal, and ulna styloid process.

Abstract
Background: Lesion size is a major determinant of treatment strategy for osteochondral lesions of the talus (OLTs). Although magnetic resonance imaging (MRI) is commonly used in the preoperative evaluation of OLTs, the reliability of the MRI measurement compared with the arthroscopic measurement is unknown. Purpose: To compare preoperative lesion size measured on MRI versus intraoperative lesion size measured during arthroscopy. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: We retrospectively reviewed a consecutive series of patients treated with bone marrow stimulation for OLTs. The diameter of the lesion was measured at its widest point in 2 planes, and MRI measurements were compared with those made during arthroscopy using a custom-made graduated probe. Results: A total of 39 patients with 45 OLTs were analyzed. Mean ± SD area measurements on MRI were significantly greater than the equivalent arthroscopic measurements (42.2 ± 30.5 vs 28.6 ± 23.1 mm2, respectively; P = .03). Compared with the arthroscopic measurement, MRI overestimated OLT size in 53.3% (24/45) of ankles and underestimated OLT size in 24.4% (11/45). The mean MRI diameter measurement was significantly greater than the arthroscopic measurement in the coronal plane (MRI diameter vs arthroscopic measurement coronal plane, 6.1 ± 2.6 vs 4.9 ± 2.3 mm, P = .03; sagittal plane, 8.0 ± 3.6 vs 6.3 ± 3.6 mm, P = .05). Further, MRI overestimated coronal diameter in 48.9% (22/45) of ankles and underestimated in 26.7% (12/45) compared with the arthroscopic measurement. Similarly, sagittal plane MRI diameter measurements overestimated lesion size in 46.7% (21/45) of ankles and underestimated lesion size in 28.9% (13/45) compared with the arthroscopic findings. Conclusion: In a majority of lesions, MRI overestimated OLT area and diameter compared with arthroscopy. Surgeons should be aware of the discrepancies that can exist between MRI and arthroscopic measurements, as these data are important in making treatment decisions and educating patients.

Abstract
BACKGROUND: The aim of this study was to report the incidence of associated osteochondral lesions (OCLs) on postop CTs, which may benefit from arthroscopic treatment, in patients with rotational type ankle fractures with syndesmotic injury. The diagnosis and treatment of associated OCLs may be an additional benefit of the use of arthroscopy in the management of rotational type ankle fractures with syndesmotic injury. METHODS: We retrospectively reviewed data of a prospective cohort study of patients who underwent open reduction and surgical fixation of an ankle fracture with syndesmotic injury. These patients underwent routine bilateral postoperative CT assessment. Two independent observers classified ankle fractures according to Weber and OCLs according to the classification system by Berndt and Harty. Fifty-nine patients were included. There were 19 (32%) Weber B type ankle fractures and 39 (66%) Weber C type fractures. One patient (2%) had fixation for a medial malleolus fracture and syndesmotic rupture without fibula fracture. RESULTS: Talar OCLs were present in 8 patients (14%). In one patient, 2 OCLs were found, which resulted in a total of 9 lesions. Two lesions were found on the medial side, both anterior. The other 7 were located laterally, of which 1 was anterior, 3 central, and 3 posterior on the talus. According to the Berndt and Harty classification, 1 was classified as stage I, 4 as stage III, and 4 as stage IV. CONCLUSION: The prevalence of OCLs in ankle fractures with syndesmotic instability was 14%. We believe that lesions were arthroscopically accessible in 6 patients (10%). Moreover, most lesions were located on the lateral dome, and thus also potentially approachable through an anterolateral arthrotomy during open reduction and internal fixation. The majority of OCLs found in this series were Berndt and Harty type III or IV, and so likely would preferably have been addressed during the index procedure. LEVEL OF EVIDENCE: Level III, diagnostic cohort study.

Abstract
Residual symptoms often persist even after successful operative reduction and internal fixation (ORIF) of ankle fractures. Concurrent ankle arthroscopic procedures (CAAPs) have been proposed to improve clinical outcomes; however, a dearth of evidence is available supporting this practice. The purpose of the present study was to investigate the reoperation and complication rates after ORIF of ankle fractures with and without CAAPs. Reoperations and complications after ORIF of ankle fractures were identified using the PearlDiver database from January 2007 to December 2011. The CAAPs included bone marrow stimulation, debridement, synovectomy, and unspecified cartilage procedures. Reoperation procedures consisted of ankle fracture repeat fixation, arthroscopic procedures, osteochondral autograft transfers, and ankle arthrodesis. Of the 32,307 patients who underwent ankle fracture fixation, 248 received CAAP and 32,059 did not. No significant difference was found in the reoperation rate between the 2 groups (7.7% versus 8.6%; odds ratio 0.89; 95% confidence interval 0.55 to 1.42; p = .61). Of the 248 patients in the CAAP group, 19 (7.7%) underwent reoperation, of which 13 (68.4%) were arthroscopic debridement and 6 were either ankle refixation or osteochondral autograft transfer. For the non-CAAP group, 3021 reoperation procedures were performed, consisting of ankle refixation in 83.2%, arthroscopic procedures in 14.3%, and ankle arthrodesis in 2.5%. The complication rate in the non-CAAP group included wound dehiscence in 2.4%, wound surgery in 0.4%, deep vein thrombosis in 0.8%, and pulmonary embolism in 0.4%. No complications were detected in the CAAP group. Ankle fracture fixation with CAAPs did not increase the postoperative reoperation rate compared with ankle fracture fixation without CAAPs.

Abstract
INTRODUCTION This meta-analysis was performed to determine whether the arthroscopically assisted open reduction and internal fixation (ORIF) for ankle fractures is more beneficial than the conventional ORIF. METHODS Articles in electronic medial databases were searched between March 1983 and August 2016, including Pubmed and SCOPUS. We included the studies with comparative design comparing the surgical outcomes between the arthroscopically assisted ORIF for ankle fractures and the conventional ORIF. Finally, two RCTs and two retrospective comparative studies were included for analysis. Mean and standard deviation (SD) of postoperative functional scores, number of subjects, and P-values were extracted from the studies. In addition, postoperative follow-up period, fracture type, and study quality were collected. RESULTS The pooled effect size of the four studies 0.535 (95% CI, 0.247-0.823) in Hedges's g, which favored the arthroscopically assisted ORIF over conventional ORIF. There was no evidence of publication bias in funnel plot and in Egger's test (p=0.534). CONCLUSION The arthroscopically assisted ORIF for ankle fractures were more beneficial than the conventional ORIF in the current evidences. However, since it needs more medical cost and longer operation time, possible additional complications and cost effectiveness are to be validated in future studies.

BMC Musculoskelet Disord 2016; 17:210. [PMID: 27175917 PMCID: PMC4865995 DOI: 10.1186/s12891-016-1063-2] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2016] [Accepted: 05/07/2016] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND An anatomical reconstruction of the ankle congruity is the important prerequisite in the operative treatment of acute ankle fractures. Despite anatomic restoration patients regularly suffer from residual symptoms after these fractures. There is growing evidence, that a poor outcome is related to the concomitant traumatic intra-articular pathology. By supplementary ankle arthroscopy anatomic reduction can be confirmed and associated intra-articular injuries can be treated. Nevertheless, the vast majority of complex ankle fractures are managed by open reduction and internal fixation (ORIF) only. Up to now, the effectiveness of arthroscopically assisted fracture treatment (AORIF) has not been conclusively determined. Therefore, a prospective randomised study is needed to sufficiently evaluate the effect of AORIF compared to ORIF in complex ankle fractures. METHODS/DESIGN We perform a randomised controlled trial at Munich University Clinic enrolling patients (18-65 years) with an acute ankle fracture (AO 44 A2, A3, B2, B3, C1 - C3 according to AO classification system). Patients meeting the inclusion criteria are randomised to either intervention group (AORIF, n = 37) or comparison group (ORIF, n = 37). Exclusion criteria are fractures classified as AO type 44 A1 or B1, pilon or plafond-variant injury or open fractures. Primary outcome is the AOFAS Score (American Orthopaedic Foot and Ankle Society). Secondary outcome parameter are JSSF Score (Japanese Society of Surgery of the Foot), Olerud and Molander Score, Karlsson Score, Tegner Activity Scale, SF-12, radiographic analysis, arthroscopic findings of intra-articular lesions, functional assessments, time to return to work/sports and complications. This study protocol is accordant to the SPIRIT 2013 recommendation. Statistical analysis will be performed using SPSS 22.0 (IBM). DISCUSSION The subjective and functional outcome of complex ankle fractures is regularly unsatisfying. As these injuries are very common it is essential to improve the postoperative results. Potentially, arthroscopically assisted fracture treatment can significantly improve the outcome by addressing the intra-articular pathologies. Given the absolute lack of studies comparing AORIF to ORIF in complex ankle fractures, this randomised controlled trail is urgently needed to evaluate the effectiveness of additional arthroscopy. TRIAL REGISTRATION ClinicalTrials.gov reference: NCT02449096 (Trial registration date: April 7th, 2015).
