Arthroscopic treatment of ankle impingement syndrome / 中华创伤杂志(英文版)

Arthroscopic treatment of ankle impingement syndrome (AIS) is a minimally invasive surgical procedure used to address symptoms caused by impingement in the ankle joint. This syndrome occurs when there is abnormal contact between certain bones or soft tissues in the ankle, leading to pain, swelling, or limited range of motion. Traditionally, open surgery was the standard approach for treating AIS. However, with advancements in technology and surgical techniques, arthroscopic treatment has become a preferred method for many patients and surgeons. With improved visualization and precise treatment of the arthroscopy, patients can experience reduced pain and improved functionality, allowing them to return to their daily activities sooner. In this paper, we reviewed the application and clinical efficacy the of arthroscopic approach for treating AIS, hoping to provide a reference for its future promotion.

Comparison of X-ray film and MRI in the diagnosis of posterior ankle impingement syndrome / 实用放射学杂志

Objective To compare the diagnostic value of X-ray film and MRI in the posterior ankle impingement syndrome (PAIS).Methods X-ray film and MRI data of 72 cases with posterior ankle pain were analyzed retrospectively.Passive plantar flexion test and diagnostic blocking were used as the diagnostic criteria.72 patients with posterior ankle pain were divided into PAIS group and non PAIS group.X-ray film and MRI findings in the PAIS group and non PAIS group were compared,and features which had differential diagnostic value were selected for calculating and comparing the efficacy of X-ray film and MRI in diagnosing or excluding PAIS.Results There was no significant difference for X-ray film findings such as os trigonum osteosclerosis(χ2 =2.947,P =0.086),os trigonum cystic changes(χ2 = 3.031,P =0.082)and posterior ankle soft tissue swelling(χ2 = 1.610,P =0.205 )between the PAIS group and the non PAIS group.There was significant difference for MRI features such as os trigonum or posterior talus bone marrow edema(χ2 =38.868,P =0.000 ),edema around os trigonum(χ2 =39.919,P =0.000 )and tenosynovitis of the flexor hallucis longus (χ2 =8.854,P =0.003)between the PAIS group and the non PAIS group.There was no significant difference for MRI features such as posterior ankle synovitis(χ2 =2.534,P =0.119)and posterior ankle ligament thickening(χ2 =1.515,P =0.218)between the PAIS group and the non PAIS group.Conclusion Using passive plantar flexion test and diagnostic blocking as the gold standard,the diagnostic efficacy of MRI on PAIS is obviously higher than that of X-ray film.MRI can significantly improve the diagnostic accuracy of PAIS,and avoid unnecessary diagnostic blocking.

Ankle arthroscopy for ankle impingement syndrome through anterior and posterior passage / 中国骨伤

<p><b>OBJECTIVE</b>To analyze clinical efficiency and intraoperative considerations of ankle arthroscopy for ankle impingement syndrome through anterior and posterior passage.</p><p><b>METHODS</b>From April 2011 to April 2015, the clinical data of 17 patients diagnosed as ankle impingement syndrome were performed arthroscopy, including 12 males and 5 females, with an average age of 32.4 years (ranging from 22 to 47). Ankle arthroscopy cleaning were carried out according to clinical symptoms and radiological imaging, crashed part were cleaned too. Non steroidal anti-inflammatory drugs and intra-articular injection of sodium hyaluronate were used as conventional postoperatively treatment. AOFAS score and Ogilvie-Harris score were used to assess preoperative situation and postoperative situation.</p><p><b>RESULTS</b>Intra-operative conditions showed 8 cases with anterior lateral impingement syndromes, 2 cases with anterior medial impingement syndromes, 2 cases with posterior impingement syndromes and 3 cases combined with anterior and posterior impingement syndromes. Distal bundle of anterior tibiofibular ligament, anterior talusfibular ligament and synovial tissue and scar tissue were cleared up during operation. Four patients were combined with concomitant articular cartilage injury, and damage area were about 1 mm×3 mm to 1.5 mm×4 mm. Microfracture treatment were performed by 1.2 mm diameter Kirschner wire. All patients were followed up from 8 to 24 months with an average of 14.3 months. AOFAS score increased from 62.3±5.20 preoperatively to 87.6±5.40 postoperatively, Ogilvie-Harris ankle score increased from 6.70±0.98 preoperatively to 12.80±1.21 postoperatively. No neurovascular damage, wound infection or wound healing problem occurred. Ankle swelling were appeared with different degrees, but disappeared at 4 to 8 weeks postoperatively.</p><p><b>CONCLUSIONS</b>For ankle impingement syndrome patients, ankle arthroscopy through anterior with posterior passage could effectively clear up bone and soft tissue impingement. Postoperatively non-steroidal anti-inflammatory drugs and intra-articular injection of sodium hyaluronate could effectively relieve ankle pain and swollen and achieve good therapeutic effect.</p>

Ankle Impingement Syndrome / 대한족부족관절학회지

The ankle impingement syndrome is an established cause of ankle dysfunction. In most cases with suspected ankle impingement, the diagnosis can be possible on the basis of mechanism of injury involved and the clinical examination. An appropriate imaging study should be selected where clinical doubt about the exact diagnosis exists. Radiography plays an important role in the initial assessment of these conditions, especially in anterior and posterior impingement. Magnetic resonance arthrography seems to be the most accurate means of assessing the capsular abnormalities present in anterolateral and anteromedial impingement and for confirmation of possible concomitant injury. Surgical treatment can be considered for the patients who did not respond to conservative treatment for more than 6 months, and has a low complication rate and a high level of success.
