Arthroscopic Treatment of Posterior Ankle Impingement Syndrome: Mid-Term Clinical Results and a Learning Curve

“…[29][30][31] Arthroscopic examination brought new knowledge to the physicians on the posterior ankle lesions, including soft-tissue impingements, 32 and several authors published good short-term results of the arthroscopic treatment for the PAIS with follow-up periods of 12 to 30 months. [1][2][3]6,16,17,19,20,26 López Valerio et al 4 reported mid-term results of arthroscopic treatment for the PAIS with a mean follow-up period of 6.5 years, whereas Georgiannos et al 5 reported those with a mean follow-up period of 5 years. The cause of the PAIS in these 2 reports was os trigonum, and patients with a large talar process or soft-tissue impingement were not included.…”

“…Level of Evidence: Level IV, therapeutic case series.E lite athletes, such as football players and dancers, are the most common patients to develop posterior ankle impingement syndrome (PAIS). [1][2][3][4] Bony impingement by an os trigonum or by a large posterior talar process is the major cause of the syndrome. [5][6][7][8] In…”

“…[17][18][19][20][21] It is essential to understand the local anatomy of the posterior ankle to avoid any injuries to the normal structures of the joint, tendons, vessels, and nerves. [22][23][24][25] Although there have been several reports on the arthroscopic treatment of the PAIS with a short-term follow up, [1][2][3]6,16,17,19,20,26,27 very few reports exist on mid-term results of arthroscopic treatment for the PAIS and their relationship with the skill of posterior arthroscopy.…”

Hindfoot endoscopic release of the posterior ankle capsuloligamentous structures improves ankle dorsiflexion range, function and pain in patients with painful limitation of ankle dorsiflexion

“…Hindfoot endoscopy is an effective treatment option for posterior bony or soft-tissue impingement. It enables access to posterior ankle cartilage defects and has also been shown to have a quicker recovery than open procedures 4 7 14–16. The authors therefore advocate arthroscopic release in favour of an open release and suggest that anterior ankle arthroscopy is performed at the same time as hindfoot endoscopic release in these patients because after the posterior release is performed and ankle dorsiflexion is restored, anterior soft tissue and bone may impinge as a result.…”

Surgical Outcomes of Os Trigonum Syndrome in Dancers: A Case Series

“…7,15 Additionally, a hindfoot endoscopic technique 33 has shown comparable clinical outcomes regarding pain, function, and satisfaction and may shorten the recovery time and result in lower complication rates. 4,12 However, it limits access to concomitant FHL pathology. Despite theoretical advantages of greater access to the posterior ankle and subtalar joint with arthroscopy, imaging has ruled out addressing any posterior articular issues.…”
