HemiCAP® implantation after failed previous surgery for osteochondral lesions of the talus.
Foot and Ankle Surgery : Official Journal of the European Society of Foot and Ankle Surgeons 2021 January
BACKGROUND: The aim of this study is to enhance data about the effectiveness of HemiCAP® implantation after failed previous surgery for osteochondral defects (OCDs).
METHODS: 12 consecutive patients were retrospectively included in this study. The American Orthopedic Foot and Ankle Society Score (AOFAS), the Visual Analogue Scale (VAS) score for pain, the sub-scales Pain and Disability of the Foot Function Index (FFI-P and FFI-D) Score, and the patients' satisfaction were evaluated.
RESULTS: AOFAS increased from poor to fair (p < 0.001), VAS score decreased from moderate to mild pain (p = 0.001), the final FFI-P and FFI-D were 37.50 ± 18.54 and 33.44 ± 16.24, respectively (p < 0.001). Five patients were not satisfied, three were moderately satisfied and four were highly satisfied. One implant repositioning, one ankle fusion (implant failing) and an additional surgery (double arthrodesis) were performed during the follow-up. Neither intra- nor postoperative complications were registered.
CONCLUSION: Despite the clinical improvement, pain was still present at the final follow-up. Metal resurfacing might not be considered a definitely valid alternative for treatment of OCDs after failed previous surgery.
LEVEL OF EVIDENCE: Level III, retrospective study.
