Purpose: To evaluate the clinical characteristics and the functional results of the osteochondral lesions of the talus (OLT) treated with arthroscopic osteochondroplasty. Materials and Methods: The study was based on 25 cases (25 feet) of osteochondral lesion of talus that were treated with arthroscopic osteochondroplasty from May 1997 to June 2005 with at least 1 year follow-up. Follow-up period was average 21.8 months. The average age was 37.2 years old. Male patients were 22 while female were 3. Postoperative evaluation was performed with American Orthopedic Foot and Ankle Society (AOFAS) Functional score, patient satisfaction and complications. Results: Ninety-two percent of patients had trauma history. Seventy-two percent of the lesions were located at the medial dome. As for the cartilage classification, 56% were fibrillation/fissure lesions while 44% were flap tears. Visual analogue scale (VAS) pain score improved from 6.8 points to 2.2 points, and AOFAS score improved from 71.3 points to 87.3 points. Eighty-eight percent of the patients were satisfied with the surgery and average period of returning to previous job was 6.5 weeks. Conclusion: We concluded that the arthroscopic osteochondroplasty is a viable surgical option for the osteochondral lesion of the talus.

Arthroscopic treatment has been reported to provide effective improvement of ankle function when used in treatment of small osteochondral lesion of talus; however, favorable long-term results have been less predictable for large osteochondral lesion of talus. In cases in which primary arthroscopic treatment fails, the decision regarding which subsequent technique to choose has become increasingly difficult, as good clinical outcomes may be unlikely for such patients irrespective of the surgical technique used. Redomicrofracture should be used judiciously for treatment of osteochondral lesion of talus in which arthroscopic treatment has failed.

Purpose: The purpose of this study was to evaluate outcome of ankle arthroscopy with high anteromedial and anterolateral portals for osteochondral talar lesion. Materials and Methods: A prospective study was conducted between March 1992 and January 2000 by one surgeon. Total 48 patients who had osteochondral talar lesion were included. Using high anteromedial and anterolateral portals, arthroscopic treatment was performed. A functional evaluation was performed with the Karlsson scoring scale. Results: Of the 48 patients, 28 cases had anterolateral talar lesion and 18 cases had medial talar lesion and 2 cases had central lesion. The 42 cases(87.5 %) had trauma history. On Karlsson scoring scale, anterolateral talar lesion was better than medial talar lesion(p=0.035). Conclusion: Using high portals, we could get better visualization of talar dome and posterior chamber of ankle, and do some limited procedures without additional portals. Osteochondral lesions were treated successfully only when they were traumatically induced and localized without diffuse chondromalacia of talus and tibia.

A medial opening wedge supramalleolar osteotomy (SMO) introduced by Takakura et al. is a useful realignment procedure for patients with ankle joint arthritis and varus malalignment by shifting the weight-bearing axis laterally and redistributing the loads on the ankle joint. When pain persists after arthroscopic microfracture in patients with medial osteochondral lesion of the talus (OLT), redo arthroscopy, osteochondral autograft transplantation, autologous chondrocyte implantation, or matrix-induced chondrogenesis might be indicated. On the other hand, there is insufficient scientific evidence for realignment surgery through SMO, while the effect of realignment surgery has been studied consecutively for osteochondral lesions of the knee. Therefore, this paper reports a patient with medial OLT who underwent redo arthroscopy combined with SMO for persistent pain after primary arthroscopic microfracture.

Many articles on operative treatment strategies for osteochondral lesions of the talus (OLT) have been published. On the other hand, there are only a few reports on the conservative treatment of OLT. Understanding the natural history of OLT is essential to establishing the correct treatment. Conservative treatment might lead to comparable clinical outcomes compared to the current options of the operative treatment in isolated OLT lesions. OLT lesions can be divided into two (or possibly three) types. Hence, the prognosis and outcome of certain operative treatments should be evaluated further. The prognosis of OLT combined with instability or malalignment appears poorer than that of isolated OLT lesions. Therefore, concomitant pathologies should be evaluated together when treating patients with OLT.

Bone marrow aspirate concentrate and matrix-induced chondrogenesis (BMIC) is an interesting treatment option for osteochondral lesions of the talus with promising short- to mid-term results. The various terminologies used to describe this surgical method need to be addressed. These include bone marrow-derived cell transplantation, matrix-induced bone marrow aspirate concentrate, and matrix-associated stem cell transplantation. BMIC is a one-stage, minimally invasive surgery performed arthroscopically or using a mini-open arthrotomy approach without a malleolar osteotomy in most cases. The lesion is replaced with hyaline-like cartilage, and treatmentrelated complications are rare. BMIC is a safe and effective treatment option and should be considered in large lesions or lesions with a prior treatment history.

Microfracture as a reparative strategy is the treatment of choice for an osteochondral lesion of talus. Although the results of microfracture are generally excellent, at least 30% of patients who received microfracture have acute or chronic ankle pain with several or unknown causes. The most important factor for unsatisfactory outcome after microfracture is the size of the lesion. For failed osteochondral lesion of talus, the second options are autologous osteochondral graft, autologous chondrocyte implantation, or re-microfracture. In this article, we present the autologous chondrocyte implantation as a second procedure for failed microfracture and compare its clinical outcome with other methods based on a literature review.

Despite the increasing number of osteochondral lesions of the talus, there are a lack of definite evidence-based treatment protocols. Several types of treatments are available, each having their advantages and disadvantages. First-line therapy consists of well-conducted conservative treatment. Surgical treatment is the second choice. Treatments are chosen based on the size of the lesion, location, chronicity, and the condition of the neighboring cartilage. This article reviews the current updates in the treatment of osteochondral lesions of the talus to help clinicians use the available treatment strategies more efficiently.

Purpose: The purpose of this study is to review clinical and radiologic changes after arthroscopic operation without bone graft for osteochondral lesion with subchondral cyst on the talus. And we compared the results with those without cyst. Radiologic changes were also observed. Materials and Methods: Arthroscopic microfrature or abrasion arthroplasty was performed on 10 caeses of osteochondral lesions with subchondral cyst and 20 cases without cysts. Preoperative and postoperative symptoms were evaluated by Ankle-Hind foot scale of AOFAS and the score of two groups were compared(t-Test : Paired Two Test for Means). Radiologic evaluation was performed after operation on patients with osteochondral lesion with cyst. Results: On patients of osteochondral lesion with subchondral cyst on talus, there was clinical improvement compared to the preoperative status and compared to patients without cysts(P=0.01) after arthroscopic operation. We could get increase of density and decrease of size of cystic lesion on plain film with time passage. Conclusion: We report 10 cases with osteochondral lesion with subchondral cyst on talus which resulted in clinical and radiological improvement after arthroscopic microfracture or abrasion arthroplasty without bone graft.
