Background/Objectives: The objective of this study was to test the hypothesis that vitamin D deficiency (i.e., serum 25-hydroxyvitamin D (25(OH)D) ≤ 20 ng/mL) associates with the increased occurrence and shortened time to a knee osteoarthritis (OA) diagnosis after anterior cruciate ligament reconstruction (ACLR). Methods: This study consisted of a retrospective, case-control design. The inclusion criteria consisted of (1) patients (≥18 y) who underwent arthroscopic ACLR with (cases; n = 28) and without (controls; n = 56) a subsequent knee OA diagnosis (≥90 d from the date of ACLR) and (2) with a documented serum 25(OH)D concentration after ACLR (and before a knee OA diagnosis for the cases). Controls were matched (2:1) to cases based on sex, age at ACLR, date of ACLR, and body mass index. After matching, patients were separated into two groups: (1) vitamin D deficient (serum 25(OH)D ≤ 20 ng/mL) or (2) non-vitamin D deficient (serum 25(OH)D > 20 ng/mL). Data were extracted from the medical records. Results: Thirty-one percent (n = 26) of patients included were vitamin D deficient. Fifty percent (n = 13) of the vitamin D deficient and twenty-six percent (n = 15) of the non-vitamin D deficient patients were subsequently diagnosed with knee OA (p = 0.03). Time from ACLR to a knee OA diagnosis was significantly (p = 0.02) decreased in the vitamin D deficient (OA-free interval, 95% confidence interval [CI] = 7.9 to 10.9 y) compared to the non-vitamin D deficient group (OA-free interval, 95% CI = 10.5 to 12.5 y). Conclusions: Vitamin D deficiency after ACLR may serve as a prognostic biomarker for knee OA following ACLR. [ABSTRACT FROM AUTHOR]

This study analyzes the outcomes of patients treated for high energy midfoot injuries with temporary stabilization (TS) prior to definitive operative fixation compared to a control group (C) treated initially with splint only. Three Level 1 trauma centers reduced and temporized high energy Lisfranc injuries. A matched control group was compared with the intervention group. Clinical parameters, complications and need for additional surgery were evaluated. There were 15 patients in group C and 29 patients with temporary stabilization (TS). Both the TS and C groups demonstrated no significant difference in the number of additional operations, infection rate, incidence of deep vein thrombosis (DVT), nonunion and need for orthotics postoperatively (p > 0.05). Staged treatment of high energy Lisfranc injuries in the TS group led to a delay in definitive fixation or arthrodesis while having a similar minimal complication rate relative to the controls. This is a Level III, Retrospective Case Control Study. (Journal of Surgical Orthopaedic Advances 29(3):154-158, 2020).

The purpose of this study was to analyze the clinical outcomes of patients treated for high-energy midfoot (Lisfranc) injuries with initial temporization of an external fixator before definitive fixation. A retrospective chart review at two level 1 trauma centers was completed. Clinical parameters including demographics and comorbidities were evaluated in addition to hospital and clinical data. Time to full weight bearing took an average of 4.4 months, and with the numbers available no significant difference (p < .05) was found between the open reduction and internal fixation (ORIF) group and the arthrodesis group in regard to length of stay, days from initial reduction with an external fixator to definitive fixation, time to full weight bearing, or return to work. Staged treatment of high-energy Lisfranc injuries with external fixation demonstrated minimal soft tissue complications similar to other series reported in the literature. Definitive stabilization with either ORIF or arthrodesis produced similar results in staged treatment of these injuries. (Journal of Surgical Orthopaedic Advances 28(1):24-30, 2019).
