Intra-articular plica causing ankle impingement in a young handball player: a case report

First Metatarsophalangeal Joint Pathology in the Athlete

Movement of the first metatarsophalangeal joint is an essential function of many sports. Because of the high demand on this relatively small joint, it is prone to the development of several notable pathologic derangements that can prevent full and pain-free athletic performance. A complete understanding of the joint anatomy and a careful physical examination and history collection is crucial to identifying an accurate diagnosis. Treatment should be pathology specific and should keep in mind the career expectations of the athlete.

Intra-articular fibrous bands at the tibiotalar joint: diagnosis and outcomes of arthroscopic removal in 4 ankles

The authors retrieved the records of 4 patients that exhibited unusual structural anomalies or pathologies, notably the presence of a fibrous band at the anterior aspect of the tibiotalar joint, observed during arthroscopic exploration or treatment between January and December 2019. Only 1 patient had surgical antecedents on the ipsilateral ankle (extra-articular tenodesis 10 years earlier). The remaining 3 patients had no surgical antecedents on the ipsilateral ankle. The fibrous band was removed in all patients during arthroscopic Brostöm procedure or exploration. For the first 3 patients, the intra-articular fibrous band was not observed prior to arthroscopy by either the senior surgeon or radiologist on any of the images (2 MRIs and 1 CTA), but retrospective inspection confirmed that the intra-articular fibrous band was present but had been overlooked.

At a follow-up of 22.3 ± 5.0 months (range, 15–26), all patients reported a decrease in pVAS (− 5.0 ± 2.6, range, 2–8), and an improvement in AOFAS (51.0 ± 17.7, range, 26–65), EFAS (14.5 ± 8.7, range, 6–23) and EFAS sport (8.0 ± 5.3, range, 2–10).

This case report corroborates the findings of an earlier discovery of an intra-articular fibrous band in 4 ankles, with more detailed information for clinical and radiologic diagnosis, as well as outcomes of arthroscopic removal. Clinicians should beware of such foreign bodies in the ankle, particularly in patients with history of sprains, and consider arthroscopic removal in cases with persistent pain and/or functional impairment.

Three-Portal Approach of Arthroscopy for Anterior Ankle Impingement Syndrome: A Propensity Score-Matched Analysis

Objective

To introduce a 3‐portal approach of arthroscopic for anterior ankle impingement syndrome and to compare this method with 2‐portal arthroscopy.

Methods

From July 2011 to April 2019, a total of 52 patients (30 females, 22 males) with anterior ankle impingement syndrome underwent surgery with 2‐portal approach (anterior medial and anterior lateral approach; N = 26) and modified 3‐portal approach (anterior medial, anterior lateral, and an accessory anterior median approach; N = 26) of arthroscopic were recruited retrospectively after we performed a propensity score‐matched analysis (PSMA). The mean age at operation time was 44.1 years (range from 22 years to 74 years) and the mean follow‐up duration was more than two years (range from 2 years to 9 years). Clinical outcomes of all patients were evaluated according to the range of motion (ROM, dorsal flex angle), the American Orthopaedic Foot and Ankle Society lesser metatarsophalangeal interphalangeal scale (AOFAS), the visual analogue scale (VAS), and the operation time before and after the surgery.

Results

During the follow‐up period, both two groups indicated significant improvement in these function scores. Clinical assessment showed that for the 2‐portal approach of arthroscopic the total average of AOFAS scores were significantly increased from preoperative 59.91 ± 5.281 points to postoperative 76.18 ± 1.471 points (P = 0.02), the VAS scores were significantly decreased from preoperative 7.64 ± 0.924 points to postoperative 4.18 ± 0.982 points (P = 0.04), and the dorsal flex angle was significantly increased from preoperative 12.27° ± 6.467° to postoperative 21.36° ± 3.931° at the last follow‐up (P = 0.035). However, for the 3‐portal approach of arthroscopic the total average of AOFAS scores were significantly increased from preoperative 48.64 ± 9.646 points to postoperative 79.18 ± 6.555 points (P = 0.015), the VAS scores were significantly decreased from preoperative 7.82 ± 0.751 points to postoperative 2.64 ± 1.629 points (P = 0.01), and the dorsal flex angle was significantly increased from preoperative 13.64° ± 7.775° to postoperative 20.45° ± 6.502° at the last follow‐up (P = 0.045). There were no significant differences among the dorsal flex angle, the AOFAS scores, and the VAS scores between the two groups at the last follow‐up (P > 0.05). Although the operation time of the 3‐portal approach of arthroscopic (74.82 ± 18.395 min) was longer than that of the 2‐portal approach of arthroscopic (92.55 ± 27.153 min), the difference was not significant (P > 0.05).

Conclusion

Both the 2‐portal and the 3‐portal approach of arthroscopic provides almost the same satisfactory clinical outcomes for anterior ankle impingement syndrome, but we strongly suggest the 3‐portal approach of arthroscopic which can supply greater joint contact area to treat advanced impingement syndrome for a good result.

Ankle Impingement Caused by an Intra-articular Plica: A Report of 2 Cases

Entrapment of soft tissues in the anterolateral gutter of the ankle can cause impingement. When symptomatic, patients complain of chronic ankle pain exacerbated with dorsiflexion. Symptoms of instability and a history of recurring ankle sprains are common findings. Plain radiographs and magnetic resonance imaging may assist clinicians in identifying associated pathology. We present 2 cases of ankle impingement occurring in the setting of equivocal examination and imaging findings. In both cases, arthroscopy revealed a likely congenital, intra-articular plica.
