摘要

Background

Arthroscopic bone marrow stimulation (BMS) is widely used for treating small osteochondral lesions of the talus (OLT). Although its short-term efficacy is well-established, mid- and long-term outcomes remain ambiguous. This study evaluates the 5-year follow-up results of arthroscopic BMS with a focus on pain and functional recovery.

Methods

We conducted a cohort study at a traumatology and orthopedic department on patients with OLT during 5-year follow-up period. Follow-up evaluations included magnetic resonance imaging (MRI) and computed tomography (CT) scans. Pain levels and functional outcomes were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) score and the Visual Analogue Scale (VAS) at one and five years postoperatively. The study was conducted retrospectively, follow-up time points were determined in accordance with the standard protocol adopted in the clinic.

Results

The mean AOFAS score significantly improved from 67.1 ± 9.4 preoperatively to 86.5 ± 12.5 at one year (p < 0.05) and remained consistent at five years (85.7 ± 11.2; p > 0.05). The VAS score showed a marked reduction from 6.4 ± 1.4 preoperatively to 1.6 ± 2.3 at one year (p < 0.05) and 1.9 ± 2.4 at five years (p > 0.05). CT scans confirmed a substantial decrease in lesion size postoperatively, with no significant changes between the one- and five-year evaluations.

Conclusion

Arthroscopic BMS demonstrates sustained clinical benefits for OLT, providing significant pain relief and functional improvement over a mid-term period.
