ABSTRACT Background The purpose of this study is to identify a possible relationship between high T2-signal cyst-like foci in the tibial plateau at the meniscal root insertions and meniscal pathology. Methods Institutional review board approval was obtained for this retrospective study. HIPAA compliance was maintained throughout this study. Two radiologists reviewed 200 knee MRI examinations for tibial plateau cysts at the meniscal root insertion sites; meniscal tears and intrameniscal cysts were also noted. The knee MRI examinations were also evaluated for articular cartilage abnormalities of the medial and lateral tibial plateaus. Results Of the 200 knee examinations, 83(41.5%) demonstrated medial meniscal pathology and 47(23.5%) demonstrated lateral meniscal pathology. Twenty (10%) demonstrated cysts in at least one of the described locations; two knees had cysts in two separate locations. four (2%) examinations had cysts at the anterior horn medial meniscal insertion, and all four (100%) had medial meniscal pathology (p = 0.028). Eleven (5.5%) examinations demonstrated cysts at the posterior horn medial meniscal insertion, and eight (72.7%) had medial meniscal pathology (p = 0.031). five (2.5%) examinations demonstrated cysts at the anterior horn lateral meniscal insertion, and one (20%) had lateral meniscal pathology (p = 0.374). Two (1%) examinations demonstrated cysts at the posterior horn lateral meniscal insertion, and one (50%) had lateral meniscal pathology (p = 0.852). Conclusions Cysts at the meniscal insertions are often seen on knee MRI. Cysts located at the insertions of the medial meniscus have a statistically significant association with meniscal pathology. Level of evidence Level II, retrospective study with development of diagnostic criteria on the basis of consecutive patients.

Background: The purpose of the study was to determine when patients can safely return to driving after first metatarsal osteotomy for hallux valgus correction. Methods: After institutional review board approval, 60 patients undergoing right first metatarsal osteotomy for hallux valgus correction surgery were recruited prospectively. Patients’ brake reaction time (BRT) was tested at 6 weeks and repeated until patients achieved a passing BRT. A control group of twenty healthy patients was used to establish as passing BRT. Patients were given a novel driver readiness survey to complete. Results: At 6 weeks, 51 of the 60 patients (85%) had BRT less than 0.85 seconds and were considered safe to drive. At 6 weeks, the passing group average was 0.64 seconds. At the 8 weeks, 59 patients (100%) of those who completed the study achieved a passing BRT. Patients that failed at 6 weeks had statistically greater visual analog scale (VAS) pain score and diminished first metatarsophalangeal (MTP) range of motion (ROM). On the novel driver readiness survey, 8 of the 9 patients (89%) who did not pass disagreed or strongly disagreed with the statement, “Based on what I think my braking reaction time is, I think that I am ready to drive.” Conclusion: Most patients may be informed that they can safely return to driving 8 weeks after right metatarsal osteotomy for hallux valgus correction. Some patients may be eligible to return to driving sooner depending on their VAS, first MTP ROM, and driver readiness survey results. Level of Evidence: Level II, comparative study

Purpose To investigate a set of risk factors on the outcome of Ponseti treated idiopathic clubfeet (ICF). Methods This study was approved by the institutional review board. A retrospective analysis of prospectively gathered data over a 20-year period, at a single dedicated clubfoot clinic. Records of 333 consecutive infants with 500 ICF were analyzed. Initial Pirani score, number of casts, need for tenotomy, foot abduction brace compliance and functional score had been documented. The need for surgery after initial correction was the outcome measure. All children were followed by the same team throughout the study period. Descriptive statistics, chi-squared and multivariate analysis were performed. Results In total, 82 children (24%) with 119 feet (23.8%) were operated on, with 95.1% of feet being operated up to the age of nine years. There was a significant correlation between the Pirani score at presentation and the number of surgical procedures (chi-squared = 79.32; p < 0.001). Achilles tenotomy was done in 94.8% of patients. Pirani score of > 4.5 before casting was strongly associated with increased surgical risk (odds ratio = 1.95). When six to eight cast changes were needed, surgical prospect was 2.9 more, increasing to 11.9 when nine or more casts were needed. Conclusion Foot severity and number of cast changes were the strongest predictors for future surgery. Estimation of the risk of deformity recurrence after initial correction may help in tailoring a cost-effective personal treatment and follow-up protocol. Personalized focused protocol will help patients and caregivers and will reduce expenses. Level of Evidence Level II - prognostic study.

Abstract Background The natural history of scaphoid nonunion is the development of degenerative arthritis. A lot of information is still unclear about this progression. The purpose of this study is to analyze patients with scaphoid nonunions who had not received any kind of treatment and to assess the functional outcome. Materials and Methods This is a retrospective study that analyzed the patients with chronic scaphoid nonunions between 2009 and 2019. None of the patients received any treatment. The age at the time of injury, examination, pattern of fracture, types of scaphoid nonunion, symptoms, and duration of nonunion were noted. Diagnosis was confirmed by radiographs, computed tomography (CT) scan, and magnetic resonance imaging (MRI). Scapholunate and radiolunate angles were recorded. Pain score, modified mayo wrist score, grip strength, range of movement, and the functional outcome of these scaphoid nonunions were analyzed. A statistical correlation between the scaphoid nonunion presentations and the functional outcome was assessed. Results The mean age of the patients was 62 years (range: 35–82 years.). There were 17 male and 3 female patients. There were 9 waist and 11 proximal pole scaphoid nonunions. The mean duration of scaphoid nonunion was 34 years (range: 10–62 years). None of the patients had avascular necrosis (AVN) of the proximal scaphoid. The age at examination, gender, side of injury, fracture pattern (waist/proximal pole), fracture displacement ≤ 1 mm or > 1 mm, nonunion duration, and radiographic arthritic parameters had no significant impact on the functional outcome. Conclusions Untreated chronic scaphoid nonunion leads to the development of degenerative arthritis over a period of years, which is still unpredictable. Most of the patients become aware of the nonunion following a precedent injury or other reasons. Most of the patients have fair/good functional outcome despite reduced range of movements and grip strength. Many do not favor surgical intervention in the course of nonunion. Chronic nonunions open a lot of unanswered questions. Clinical relevance There have been numerous studies on the treatment aspects of scaphoid nonunion, with little knowledge about certain people with nonunion who did not have any kind of treatment. The demographics, clinical findings, and radiological parameters do confirm the progression of these nonunion to arthritis, but most of them had fair-to-good outcome throughout their life. It opens our thinking about the real need of treatment in such nonunions and raises numerous questions about the disease. Level of evidence This is a Level IV study.

ABSTRACT Objective: To evaluate the healing of the modified inverted “Y” incision in patients with scoliosis due to myelomeningocele. Methods: Retrospective study through medical records review of patients with myelomeningocele surgically treated with a modified inverted “Y” approach between January 2013 and December 2015. Results: We analyzed the medical records of six patients. Two patients progressed with skin complications in the immediate postoperative period and only one of them required surgical intervention for debridement and suturing. In another patient, it was necessary to perform two surgical reviews due to material failure without skin complications in these interventions. Conclusions: The modified inverted “Y” technique is a great alternative to traditional incision and inverted “Y” because it has good results in patients with spina bifida associated with poor skin conditions treated surgically for correction of spinal deformities.

AbstractBackgroundAchieving a stable joint is an important yet challenging part of total knee arthroplasty (TKA). Neither manual manipulation of the knee nor instrumented sensors biomechanically characterize knee laxity or objectively characterize how TKA changes the laxity of an osteoarthritic (OA) knee. Therefore, the purposes of this study were: 1) objectively characterize changes in knee laxity due to TKA, 2) objectively determine whether TKA resulted in equal amounts of varus-valgus motion under a given load (i.e., balance) and 3) determine how TKA knee laxity and balance differ from values seen in non-osteoarthritic knees.MethodsTwo surgeons used a custom navigation system and intra-operative device to record varus-valgus motion under quantified loads in a cohort of 31 patients (34 knees) undergoing primary TKA. Similar data previously were collected from a cohort of 42 native cadaveric knees.ResultsPerforming a TKA resulted in a “looser knee” on average, but great variability existed within and between surgeons. Under the maximum applied moment, 20 knees were “looser” in the varus-valgus direction, while 14 were “tighter”. Surgeon 1 generally “loosened” knees (OA laxity 6.1°±2.3°, TKA laxity 10.1°±3.6°), while Surgeon 2 did not substantially alter knee laxity (OA laxity 8.2°±2.4°, TKA laxity 7.5°±3.3°). TKA resulted in balanced knees, and, while several differences in laxity were observed between OA, TKA, and cadaveric knees, balance was only different under the maximum load between OA and cadaveric knees.ConclusionsLarge variability exists within and between surgeons suggests in what is considered acceptable laxity and balance of the TKA knee when it is assessed by only manual manipulation of the leg. Knees were “balanced” yet displayed different amounts of motion under applied load.Clinical RelevanceOur results suggest that current assessments of knee laxity may leave different patients with biomechanically different knees. Objective intra-operative measurements should inform surgical technique to ensure consistency across different patients.Level of EvidenceLevel II prospective observational study

Navigated Tka

Purpose The development of new computer-assisted navigation technologies in total knee arthroplasty (TKA) has attracted great interest; however, the debate remains open as to the real reliability of these systems. We compared conventional TKA with last generation computer-navigated TKA to find out if navigation can reach better radiographic and clinical outcomes. Methods Twenty patients with tricompartmental knee osteoarthritis were prospectively selected for conventional TKA (n = 10) or last generation computer-navigated TKA (n = 10). Data regarding age, gender, operated side, and previous surgery were collected. All 20 patients received the same cemented posterior-stabilized TKA. The same surgical instrumentation, including alignment and cutting guides, was used for both the techniques. A single radiologist assessed mechanical alignment and tibial slope before and after surgery. A single orthopaedic surgeon performed clinical evaluation at 1 year after the surgery. Wilcoxon's test was used to compare the outcomes of the two groups. Statistical significance was set at p < 0.05. Results No significant differences in mechanical axis or tibial slope was found between the two groups. The clinical outcome was equally good with both techniques. At a mean follow-up of 15.5 months (range, 13–25 months), all patients from both groups were generally satisfied with a full return to daily activities and without a significance difference between them. Conclusion Our data showed that clinical and radiological outcomes of TKA were not improved by the use of computer-assisted instruments, and that the elevated costs of the system are not warranted. Level of Evidence This is a Level II, randomized clinical trial.

Background: Investigating the responsiveness of an instrument is important in order to provide meaningful interpretation of clinical outcomes. This study examined the responsiveness of the Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF), the PROMIS Pain Interference (PI), and the Foot and Ankle Ability Measure (FAAM) Sports subscale in an orthopedic sample with foot and ankle ailments. Methods: Patients presenting to an orthopedic foot and ankle clinic during the years 2014–2017 responded to the PROMIS and FAAM instruments prior to their clinical appointments. The responsiveness of the PROMIS PF v1.2, PROMIS PI v1.1, and FAAM Sports were assessed using paired samples t test, effect size (ES), and standardized response mean (SRM) at 4 different follow-up points. A total of 785 patients with an average age of 52 years (SD = 17) were included. Results: The PROMIS PF had ESs of 0.95 to 1.22 across the 4 time points (3, >3, 6, and <6 months) and SRMs of 1.04 to 1.43. The PROMIS PI had ESs of 1.04 to 1.63 and SRMs of 1.17 to 1.23. For the FAAM Sports, the ESs were 1.25 to 1.31 and SRMs were 1.07 to 1.20. The ability to detect changes via paired samples t test provided mixed results. But in general, the patients with improvement had statistically significant improved scores, and the worsening patients had statistically significant worse scores. Conclusion: The PROMIS PF, PROMIS PI, and FAAM Sports were sensitive and responsive to changes in patient-reported health. Level of Evidence: Level II, prospective comparative study.
