GJL is a risk factor for postoperative recurrent instability following an MBR for CLAI. Additional suture tape augmentation has been suggested to provide more strength and stability. However, the outcomes of the MBP with suture tape augmentation were unknown, which requires further exploration.
Generalized joint laxity (GJL) is a risk factor for postoperative recurrent instability following an open modified Broström repair (MBR) for chronic lateral ankle instability (CLAI). MBR with suture tape augmentation may provide more strength and stability. However, BPR with suture tape augmentation may lead to rejection of the suture tape. In addition, the outcomes of the MBP with suture tape augmentation were unknown.
350 studies on the registry are indexed under Ankle Injuries; 74 are open to participants now.
This study's planned enrollment of 86 is close to the median of 84 across 73 observational studies indexed under Ankle Injuries.

Counted across the registry records on this site, refreshed daily.
The patients who go to visit a doctor for persistent lateral ankle pain and instability over three months and invalid conservative treatment, with the age of 15 - 55 years. If the Beighton score of the patient is ≥4 and the exclusion criteria are met, he or she is going to be advised to participate in this study.

Started Jun 2021 (actual). Primary completion is estimated for Jun 2026, 60 months after the start.
Of 34 non-industry observational studies under Ankle Injuries, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 45. This study's planned 60 months is above that.
Counting every sponsor, half of 38 studies reached it within 11 months; a quarter within 5 and three quarters within 45.
How these figures are worked out, and which studies are left out of them.
