Popis: 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.
