Hindfoot Endoscopy for Posterior Ankle Pain

Arthroscopic Excision of a Symptomatic Os Trigonum

“…[2][3][4][5] This frequency underscores the need for a careful inspection of the entire FHL length including following the FHL into the fibrous-osseous tunnel distally in the inferomedial quadrant. In this series FHL pathology requiring tenolysis and debridement was present in 14 of 24 cases (58%).…”

“…However, peritendinous portals placed adjacent to the Achilles tendon in the prone patient are safe. 4,12,[16][17][18][19][20] The purpose of the study was to report the clinical outcomes of arthroscopic excision for a symptomatic os trigonum initially viewing through the posteromedial ankle portal with the motorized instrument in the posterolateral portal. Our hypothesis was that this approach would be both safe and effective and would provide comparable outcomes, a comparable complication rate, and a comparable recovery to other arthroscopic techniques.…”

“…Due to their anatomic proximity, os trigonum impingement is often associated with FHL pathology. [2][3][4][5] The literature reports the prevalence of an os trigonum to vary. 5,6 It has been estimated to be present in 7% to 14% of adults and occur bilaterally in 1.4%.…”

Hindfoot Endoscopy for the Treatment of Posterior Ankle Impingement Syndrome: A Comparison of Two Methods (a Standard Method versus a Method Using a Protection Cannula)

“…However, some anatomic studies described that the modified posteromedial portal is not completely free from potential neurovascular injury, 10) and the coaxial portal has the risk of posterior tibial tendon injury during instrument passage.…”

Tendoscopy of the Ankle

“…10 A 2.7-mm endoscope with a 30-degree tip cut is usually used when examining tendons. 2,3,5 This arthroscopic lens helps facilitate movement within the tendon sheath; the surgeon should also be cautious because this smaller-diameter scope can be more prone to breakage than larger-diameter lenses. If a significant amount of debris is anticipated (such as during a groove-deepening procedure), a 4.0-mm arthroscopic lens can be used to facilitate better flow of irrigation fluid.…”
