Purpose
In the rare case of complete proximal adductor longus avulsion injuries, scientific recommendations of surgical or conservative injury management are limited to small case series and reviews of small cohorts about treatment examples. A clear consensus regarding optimal management so far has not been made. Thus, the aim of our study was to investigate patient-related outcome measurements (PROM) after either operatively or conservatively treated patients in order to evaluate and display own decision criteria for one of the two treatment options.
Methods
In this retrospective case control study, two cohorts after MRI-confirmed, isolated, acute proximal adductor longus avulsion injury without concomitant injuries was investigated. Depending on stump retraction (less or more than 2 cm), patients of the particular cohorts had either been treated conservatively or by surgical refixation with suture anchors. All patients were asked to complete different PROM forms (Hip Osteoarthritis Outcome Score (HOS), Modified Harris Hip Score (MHHS)) in order to evaluate the particular procedures outcome.
Results
Between July 2015 and July 2018, eighteen avulsion injuries met our inclusion criteria, of which 14 were treated conservatively and operatively in equal parts and could be included into the study. The mean stump retraction of the conservative group was 1.3 cm (SD ± 0.5); patients in the surgical group had a mean stump retraction of 3.0 cm (± 1.5). Irrespective of the treatment option, all patients achieved a maximum score using the MHHS. Also in the HOS subscale respecting all day activities, almost all patients (13/14) achieved a maximum score. Instead, using the HOS subscale respecting sportive activities, one surgically and one conservatively treated patient described little restrictions compared with their pre-injury level.
Conclusion
Conservative as well as operative treatment leads to very good patient-related outcome measurements if the decision for either of the two treatment options is made upon a stump retraction above or below 2 cm. Smaller restrictions regarding pre-injury level could rather be seen in the conservative instead of the operative group, favouring a more generous perspective for surgical refixation.
