Abstract

Background: Superior capsule reconstruction (SCR) is an option for the treatment of massive, irreparable rotator cuff tears. However, which materials yield the strongest constructs remains undetermined. Purposes: We sought to investigate whether SCR with polytetrafluoroethylene (PTFE) or human dermal allograft (HDA), 2 or 3 glenoid anchors, and suture or minitape resulted in better failure load properties at the patch-glenoid interface. Methods: We conducted a biomechanical study in 30 glenoid-sided SCR repairs in Sawbones models divided into 5 groups. Each was pulled to failure to assess mode of failure, peak load (N), stiffness (N/mm), yield load (N), peak energy (N m), and ultimate energy (N m). The 5 groups were as follows: group 1—PTFE, 2 anchors, and suture; group 2—PTFE, 2 anchors, and minitape; group 3—HDA, 2 anchors, and suture; group 4—HDA, 2 anchors, and minitape; group 5—PTFE, 3 anchors, and minitape. Results: Repairs failed by button-holing of suture/minitape. Group 5 had greater peak load, stiffness, yield load, and peak energy (384 ± 62 N; 24 ± 3 N/mm; 343 ± 42 N; 4 ± 2 N m) than group 3 (226 ± 67 N; 16 ± 4 N/mm; 194 ± 74 N; 2 ± 1 N m) or group 4 (274 ± 62 N; 17 ± 4 N/mm; 244 ± 50 N; 2 ± 1 N m) and greater ultimate energy (8 ± 3 N m) than all other groups. Conclusions: This biomechanical study of SCR repairs in Sawbones models found that yield load was greater in PTFE than HDA, 3 anchors were better than 2, and minitape was no better than suture.

Abstract

Background: The management of superior labrum anterior to posterior (SLAP) tears is somewhat controversial. It is unclear if the length of time between symptom onset and surgery affects SLAP repair outcomes. Methods: Sixty-one SLAP repairs were retrospectively reviewed pre-operatively and post-operatively at 1, 6, 24 weeks, and > 2 years post-surgery. Patients were allocated to an 'early repair' or 'late repair' group based on time between symptom onset and surgery. Results: Of the 61 patients, 22 patients had surgery within six months of symptom onset. Pre-operatively, 'late repair' patients played a higher level of sport than 'early repair' patients prior to injury. Post-operatively, both groups had similar outcomes up to six months, though at six months 'early repair' patients reported a higher level of work than 'late repair' patients (p = 0.01). At > 2 years after surgery, 'early repair' patients had reduced pain and difficulty with overhead activities (p = 0.002), less stiffness (p = 0.001) and were more satisfied than 'late repair' patients (p = 0.04). Conclusions: Up to six months post-operatively, the time between symptom onset and surgery has limited effect on functional outcomes. However, at > 2 years after surgery, earlier repairs (< 6 months) are interestingly associated with better functional outcomes. Further studies are required to determine if this is a causal relationship. [ABSTRACT FROM AUTHOR]
