“…More recently, a few cases have reported subchondroplasty performed about the foot and ankle. 2,3,8,12 In the largest case series of 10 patients, subchondroplasty was performed for osteochondral lesions of the talus that had been refractory to nonoperative management with reportedly good results and no complications. 3 This series does not report on how long bone marrow lesions had been present or how long conservative management was attempted prior to subchondroplasty.…”

“…More recently, there have been several case reports and series of this procedure being performed for lesions in the foot and ankle. 2,8,12 We present a series of 5 cases in which patients developed rapid osteonecrosis, and in 2 cases collapse of their tali after undergoing acute lateral ligament reconstruction with talar subchondroplasty. These cases highlight a potential devastating complication that surgeons should be aware of when considering subchondroplasty for BMLs of the talus in the setting of acute lateral ligament injury.…”

Talar osteonecrosis is a well-described phenomenon following talar neck fracture, but is a rarely described complication after procedures about the foot and ankle. Here we describe the clinical course of 5 cases of talar osteonecrosis following injection of calcium phosphate into the talus (subchondroplasty) with or without acute lateral ligament repair after acute lateral ankle ligament injuries performed at an outside institution. Practitioners should be aware of this potentially devastating complication. Future research is indicated to determine the safety and efficacy of subchondroplasty for the talus.Level of Evidence: Level V, case series.

“…1,5,7,8,18 The foot and ankle literature is more limited, with only a few documented case reports or case series. 3,5,6,8,12,13,15 At our institution, we have identified several patients with complications after this specific procedure. As a result, we report our case series of patients who developed talar avascular necrosis (AVN) after undergoing SCP.…”

Background: Subchondroplasty (SCP) is a relatively new procedure, developed in 2007 for the treatment of bone marrow lesions (BMLs), that has shown promising results in the knee through several different case series. The foot and ankle literature, however, is sparse, with only a few documented case reports or case series. At our institution, we have identified several patients with complications after this specific procedure. As a result, we report our case series of patients who developed talar avascular necrosis (AVN) after undergoing SCP. Methods: A retrospective review was performed of patients who underwent SCP for a talar BML at our facility or who were referred to our facility after undergoing SCP at an outside institution. Patients were included if they developed radiographic evidence of talar AVN after the procedure. Patient demographics, comorbidities, concomitant intraoperative procedures, complications, and subsequent interventions were reviewed. Results: Seven patients were identified as having radiographic evidence of talar AVN after SCP. Average time interval was 23 months postoperative from index procedure to radiographic confirmation of AVN. Two of the index procedures were performed at our institution, whereas 5 of the index procedures were performed at outside institutions and referred for further management. Three patients had documented risk factors for AVN before the SCP procedure. All 7 patients were symptomatic from the AVN. Conclusion: We identified 7 patients who went on to develop talar AVN after having undergone SCP. Level of Evidence: Level IV, case series.

“…A single case report has outlined the use of calcium phosphate (CaP) for stress reactions of the cuboid with good results. 5 Additionally, CaP has been utilized in the treatment of isolated bone marrow lesions of the first metatarsal with promising outcomes. 6 Foot and ankle literature most commonly supports the use of CaP in bone marrow lesions of the talus.…”
