Background The purpose of the present study was to retrospectively compare the outcomes of patients who underwent arthroscopic thermal capsular shrinkage with those who underwent both arthroscopic thermal capsular shrinkage and arthroscopic osteochondral lesion (OCL) treatment with microfractures. Our hypothesis was that the simultaneous treatment does not negatively affect the outcome of the combined surgical procedure by influencing the postoperative rehabilitation protocol and does not significantly differ from capsular shrinkage alone in terms of subjective and objective outcomes. Methods Seventy-six patients with chronic ankle instability were treated at our department from 2004 to 2012 and reviewed retrospectively. Forty-two patients underwent arthroscopic thermal-assisted capsular shrinkage (group A), and 34 patients underwent combined arthroscopic capsular shrinkage and microfractures for OCL lesions of the talus (group B). All patients underwent a four-step surgical procedure including synovectomy, debridement, capsular shrinkage, and bracing and nonweightbearing for 21 days. In patients with OCL lesions, microfractures of the OCL were associated. Clinical assessment included objective examination, the American Orthopaedic Foot and Ankle Society ankle and hindfoot scoring system, Karlsson-Peterson score, Tegner activity level, and Sefton articular stability scale. Results The median follow-up was 6 years (range, 2–9 years). The median postoperative visual analogue scale score, American Orthopaedic Foot and Ankle Society score, and Tegner score were improved from the preoperative level for both groups (P < .001). No significant difference was found between the two groups for the subjective scores and satisfaction rate (P = not significant). Similarly, no significant difference regarding the incidence of range-of-motion restriction was reported between the two groups (P = not significant). Conclusions The association of microfractures for the treatment of osteochondral lesions does not affect the outcome following arthroscopic treatment for chronic ankle instability up to 6 years from surgery.

Background: Rotational ankle instability (RAI) is associated with the faster onset of severe ankle osteoarthritis via dysfunction of the anterior talofibular ligament, calcaneofibular ligament, and deltoid ligament. No specific clinical examination is available for RAI, and diagnostic imaging has limitations in evaluating ligament degradation. This study investigated the deltoid ligament degeneration using Hounsfield unit (HU) values on computed tomography (CT) images. Methods: Patients were enrolled in this retrospective analysis if they had undergone magnetic resonance imaging (MRI) and CT scans of the ankle. The chronic ankle instability (CAI) group comprised 20 ankles with CAI (9 men, 11 women; mean age, 28.7 years) and the control group comprised 28 ankles (16 men, 12 women, mean age, 41.3 years). The average HU values of the deep posterior tibiotalar ligament (dPTL) that constitutes the deltoid ligament were measured on coronal CT images, and MRI results were used as a reference. All patients were subdivided based on the MRI findings of dPTL injury such as fascicular disruption, irregularity, and the loss of striation. Results: A strong negative correlation was identified between age and HU values for all patients (Spearman ρ = −0.63; P < .001). The mean HU values of the dPTL for participants aged <60 years were 81.0 HU for the control group (21 ankles) and 69.5 HU for the CAI group ( P = .0075). No significant differences in the HU values were observed for the dPTL among the MRI subgroups. Conclusion: In addition to the conventional imaging examination such as stress radiographs and MRI, HU measurements of CT images could be useful for quantitatively and noninvasively evaluating degenerative changes in the deltoid ligament for CAI patients to assist the diagnosis of RAI. Level of Evidence: Level III. case-control study.
