Abstract
Purpose
The primary purpose of this study was therefore to compare the patient reported outcomes of OLTPs treated with arthroscopic bone marrow stimulation (BMS) and non-operative treatment. The secondary purpose was to compare the reintervention- and complication rates.
Methods and Materials
Patients treated either with BMS (BMS group) or any form of non-operative treatment (Non-operative group) at a minimum follow-up of 12 months were selected from a retrospective database query of patients treated between 1990 and 2020. Patients lost to follow-up/unwilling to participate were excluded for the final analysis. Eligible patients were contacted by phone and cross-sectionally included. The primary outcome was the Numeric Rating Scale (NRS) during weightbearing. Secondary outcomes included; the NRS in rest and the Foot and Ankle Outcome Score (FAOS) Additionally, the reintervention- and complication rates were collected.
Results
A total of 48 patients were included, which consisted of 15 patients for the non-operative group and 33 Patients for the BMS group. See Table 1 for the patient- and lesion baseline characteristics. The median NRS during weightbearing at final follow-up was 2 (IQR: 1-3) for the non-operative group and 1 (IQR: 0-3) for the BMS group (P= 0.17). The NRS in rest, during running, or when climbing stairs was, similarly, not significantly different between groups. None of the FAOS subscales were found to be significantly different between treatment groups. 3 Reoperations in the BMS group were recorded, none for the OLTP, however. No major complications were recorded.
Conclusion
Clinical outcomes following arthroscopic BMS and non-operative treatment yield moderate to good clinical results in this cross-sectional cohort of OLTP patients. This study was the first to report outcomes of non-operative treatment of OLTPs and to compare these to BMS, prospective studies are therefore highly needed for these understudied lesions.
