Summary: The clinical outcome of arthroscopic bone marrow stimulation in athlete patients is comparable to that observed in non-athlete patients, in a retrospective case series.




Osteochondral lesions of the talus are a common cause of ankle pain and disability in people over a wide age range and arthroscopic bone marrow stimulation (ABMS) is the first-line treatment for these lesions. The advantages of ABMS are the excellent results, low-complication rate and reduced morbidity. The aim of the procedure is to stimulate intrinsic filling of the defect with repair tissue; however, it is possible that the repaired tissue can be influenced by loading applied to the joint during sports activities. We hypothesized that sports activity affects the clinical outcome for patients following ABMS.


We retrospectively investigated 60 ankles from 60 patients treated with ABMS at our institution from October 2005 to December 2012. Patients were placed into two groups: Group I (29 ankles) included patients engaging in sports activity (age, 24.6 ± 13.6; BMI, 22.9 ± 3.1), and Group II (31 ankles) included patients not engaging in sports activity (age, 44.2 ± 18.7; BMI, 24.5 ± 3.4). We investigated the clinical outcome, sports frequency score, ankle activity score and the relationships between prognostic factors using the patients’ medical records.


The average area of the lesion was 57.2 ± 31.0 mm2 in Group I and 69.2 ± 36.2 mm2 in Group II (P = .18). The average depth of the lesion was 4.7 ± 1.3 mm in Group I and 4.6 ± 1.5 mm in Group II (P = .96). The mean American Orthopaedic Foot and Ankle Society score was 96.4 ± 6.5 and 86.8 ± 8.9 for Groups I and II, respectively (P= 0.001). A total of 82.8% (24/29cases) returned to their original sports activities. Five cases retired from the sports activities for social reasons. In Group I, there was no significant difference in sports frequency score and ankle activity score between preoperative assessment and last follow-up (P = 0.3, P = 0.3).

Discussion And Conclusion

The clinical outcome was superior in the athletes, and statistically different between the two cohorts. It was improbable that the sports activities affected the clinical outcome after ABMS. ABMS offers an effective surgical treatment for athletes.
