Background: Ankle arthroscopy has been used in Viet Duc Hospital for 4 years and now has become a routine surgery with about 200 patients, who has had ankle arthroscopy to reconstruct the anterior cruciate ligament or operate ragged meniscectomy. Objectives: Evaluate the result of ankle arthroscopy in Viet Duc Hospital and review the indication and surgical technique of ankle arthroscopy in the literature. Subject and methods: Retrospective study on 10 patients with ankle arthroscopy in Viet Duc Hospital from May 2006 to May 2007. Results: 5 patients with impingement, 4 patients with OCD lesion and 1 case of an old displaced fracture of lateral malleolar. Postoperative evaluation with Olerud Molander, ankle function improves at least 10 points and all the patients are satisfied with the results. Conclusions: Ankle arthroscopy gives good result and can be recommended for other cases.

Lateral ankle sprain is the most common ankle injuries. Patients who fail conservative treatments are candidates for modified Broström operation (MBO). Traditionally, the primary surgical treatment performed is the open MBO. Recently, there has been an evolution in the arthroscopic treatment of lateral ankle injury. Several reports reveal biomechanically equivalent results of arthroscopic vs . open MBO when using matched cadaver pairs. Also there was no difference in the clinical or radiologic outcomes between the arthroscopic and open MBO in randomized controlled trial. Therefore, arthroscopic MBO is reasonable and good alternative treatment for lateral ankle injury. Actually new techniques of arthroscopic treatment for ankle injury is introduced about arthroscopic syndesmotic repair and arthroscopic deltoid repair. Arthroscopic techniques for ankle injuries seem to develop further in the future.

Both os trigonum syndrome and osteochondral lesion of talus (OLT) are common causes of ankle pain and usually affect ballet dancers or athletes. Lateral osteochondral lesions, which usually result from traumatic event, are mostly located anterolateral talar dome but rare central or posterolateral. Moreover, there are technical difficulties such as position of patient or additional posterior portal to address posterolateral lesion by arthroscopy. Meanwhile, treatment of os trigonum syndrome using arthroscopic approach has been reported in many literatures recently. However, it has not been reported to diagnose both os trigonum syndrome and posterolateral OLT together and treat arthroscopically at one stage. The authors report a case of male patient who was diagnosed as os trigonum syndrome with posterolateral OLT and treated simultaneously by hindfoot arthroscopy. Symptom was improved immediately after the operation, and radiological findings at postoperative 16 months verified remarkable healing.

Os trigonum syndrome is a clinical disorder characterized by posterior ankle pain which occurs in excessive plantar flexion. The pain is elicited by the impingement of os trigonum between the calcaneus and the posterior edge of tibial plafond. Mostly, symptoms can be improved with nonsurgical management, however surgery is required for refractory cases. We report of a case of os trigonum syndrome in a female ballet dancer, which was successfully treated with subtalar arthroscopic excision of os trigonum.

PURPOSE: In this study, we introduced an newly developed technique of operation for fracture of lateral malleolus of the ankle. We treated the fracture by close reduction and internal fixation using arthroscopy. MATERIALS AND METHODS: From July 2006 to June 2007, we had treated 23 cases of lateral malleolar fracture (SER type) by closed reduction and internal fixation with arthroscopy and followed them up more six month. Operation time, union time, clinical and functional result were evaluated. RESULTS: After the final follow-up, all the fractures were healed with satisfactory bony union. The subjective result was excellent in 15 cases (65%), good in 8 cases (35%), the objective result was excellent in 13 cases (57%), good in 10 cases (43%), and the roentgenographic result was excellent in 17 cases (74%), good in 6 cases (26%). CONCLUSION: Closed reduction and internal fixation with arthroscopy technique is an effective treatment method in treating lateral malleolar fracture of the ankle since it offers advantages including corrective anatomical reduction and minimizing complication associated with injury of soft tissue.

From September 1992 to April 1994, we reviewed 7 patients after arthroscopic surgery for anterior impingement in the ankle, who complained ankle pain and limitation of motion. All patients were mem and main symptoms were severe pain at full dorsiflexion of ankle and limitation of motion. Bony spur was located on the anterior aspect of tibia, and it was possible to resect the tibial bony spur arthroscopically without distraction devices. Mean operation time was 55 minutes. Pain, swelling and limitation of motion were much improved. There was no postoperative complication. Arthroscopic resection of the anterior tibial bony spur is an effective treatment for anterior impingement in the ankle.

Fracture and fracture-dislocation of the ankle may be caused by a variety of mechanisms. In addition to the fracture, injury of soft tissue such as ligaments, tendons, nerves, and muscles may occur. Among these, tibialis posterior tendon injury is difficult to identify due to swelling and pain at the fracture site. There is no clear finding in radiological examination, therefore, it is found during surgery. In this case, irreducible fracture-dislocation of the ankle due to tibialis posterior tendon interposition was observed after the primary operation. The authors obtained satisfactory results in performance of a secondary operation assisted with arthroscopy.

PURPOSE: To evaluate the results of mosaicplasty and microfracture after surgical treatments for symptomatic osteochondral lesion of talus (OLT) by second-look arthroscopy. MATERIALS AND METHODS: 7 cases of mosaicplasty and 7 cases of microfracture were reviewed who undertook second-look arthroscopy at 6 months or one year after undertaking mosaicplasty or microfracture for OLT between December 2004 and October 2005. The mean age at first operation was 43.6 years (Range, 20-59) (Mosaicplasty; 43.9 years, Microfracture; 43.4 years). The mean size of cartilage defect was 15.0 x 7.7 mm in mosaicplasty and 7.1 x 6.6 mm in microfracture. Clinical outcomes were evaluated by Freiburg ankle score. Cartilage healing state was evaluated by Insall's classification for chondromalasia during second-look arthroscopy. RESULTS: By the Freiburg ankle score, 9 ankles (6 in mosaicplasty, 3 in microfracture) had excellent and 5 (1 in mosaicplasty, 4 in microfracture) had good results at the times of second-look arthroscopy. By Insall's classification, consistency of the osteochondral grafts and congruity between grafts and native cartilage (Grade I) were shown in 9 (6 ankles in mosaicplasty, 3 ankles in microfracture), a fissuring (Grade II) in one ankle of mosaicplasty, a fasciculation (Grade III) in one ankle of microfracture, and partial exposure of subchondral bone (Grade IV) in 3 ankles of microfractures. CONCLUSION: Mosaicplasty was more excellent in consistency and hardness of cartilage than microfracture. In some cases of microfracture, cartilage healing was incomplete at 6 months postoperatively, so second-look arthroscopy is necessary to identify. If incomplete cartilage healing was shown, additional procedure such as microfracture or mosaicplasty was needed.

PURPOSE: We tried to evaluate the usefulness of the arthroscopy in the operative treatment of intra-articular calcaneal fracture. MATERIALS AND METHODS:Between March 2005 and May 2008, 9 patients with intra-articular calcaneal fractures (Tongue type or Sanders type IIC) were treated with arthroscopically assisted percutaneous reduction and screw fixation. American orthopedic foot and ankle society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS), preoperative and postoperative Bohler's angle and the rate of complication were evaluated. RESULTS:AOFAS score at postoperative 1 year was 88.2 (range, 71-92), and mean VAS score was 2.8 (range, 1-4). Bohler angle was improved from preoperative mean 16.2 degrees to postoperative mean 29.7 degrees . There were no complications such as wound problem, infection or nerve injury. CONCLUSION: Subtalar arthroscopy provides precise view of posterior facet during the operation. Therefore, it can be a useful tool in treating intra-articular calcaneus fractures, especially tongue type and Sanders type IIC fractures.
