Background: The results of arthroscopic anterior labral (Bankart) repair have been shown to have high failure rate in patients with significant glenoid bone loss. Several reconstruction procedures using bone graft have been described to overcome the bone loss, including autogenous coracoid transfer to the anterior glenoid (Latarjet procedure) as well as iliac crest autograft and tibial allografts. In recent years, trends toward minimally invasive shoulder surgery along with improvements in technology and technique have led surgeons to expand the application of arthroscopic treatment. Purpose: This study aims to perform a retrospective analysis of prospectively collected data to evaluate the clinical and radiological follow up of patient who underwent anatomic glenoid reconstruction using distal tibia allograft for the treatment of shoulder instability with glenoid bone loss at 1-year post operation time point.

Between December 2011 and January 2015, 55 patients underwent arthroscopic stabilisation of the shoulder by means of capsule-labral reattachment to glenoid ream and bony augmentation of glenoid bone loss with distal tibial allograft for recurrent instability of the shoulder. Preoperative and postoperative evaluation included general assessment by the western Ontario shoulder instability index (WOSI) questionnaire, preoperative and postoperative radiographs and CT scans.

Fifty-five patients have been evaluated with mean age of 29.73 years at time of the index operation. There were 40 males (mean age of 29.66) and 15 female (mean age of 29.93). Minimum follow up time was 12 months. The following adverse effects were recorded: none suffered from recurrent dislocation, 2 patients suffered from bone resorption but without overt instability, 1 patient had malunion due to screw fracture, None of the patients had nonunion. The mean pre-operative WOSI score was 36.54 and the mean postoperative WOSI score was 61.0.

Arthroscopic stabilisation of the shoulder with distal tibia allograft augmentation demonstrates promising result at 1year follow up.

The purpose of this study was two-fold:

to examine perioperative prospective changes in pain, disability and psychosocial variables in ACL reconstructed recreational athletes over the pre-op to eight week post-op period.

All participants were recreational athletes at the time of their injuries who had patella-autograft procedure at the the Queen Elizabeth II Health Sciences Centre. Fifty-four patients (twenty-nine males; mean age = 25.4 years, SD = 8.08). Mean education was fourteen years (SD = 2.08), 32%(17) were married, 67%(36) single, and 1% was divorced. 94%(51) of the sample was Caucasian, 3%(2) Black, and 1% Asian. One quarter reported their ACL injury was due to sport-based contact, with non-contact sporting activity reported at 76%(41). All participants completed measures of pain, depression, pain catastrophizing, state anxiety pre-op, on days one and two following surgery and again at eight weeks post-op. Disability was assessed pre-op and eight weeks post-op.

Pain was varied across comparisons with preoperative pain increased twenty-four and forty-eight-hour post-op. Pain at forty-eight-hours postoperative was significantly higher than pain reported at eight-weeks post-op. Catastrophizing did not differ from the pre-op to twenty-four-hour post-op but did drop from twenty-four to forty-eight-hours and forty-eight-hours to eight-weeks post-op. Pre-op depression increased twenty-four-hour post-op, but not from twenty-four to forty-eight-hours and declined at eight-weeks. Anxiety increase pre-op to twenty-four-hours but not from twenty-four to forty-eight-hours but did drop from forty-eight-hours to eight-weeks.Disability did not change over time. Regression showed age or gender did not predict disability but forty-eight hour pain and catastrophizing did.

These data indicate that pain and psychological variables change over time of ACL recovery. Results suggest that pain and distress peek during acute post-op period. As well, post-op catastrophizing predicts disability at eight weeks post-op which may indicate that catastrophizing may be related to behaviours related to slower recovery following ACL reconstructive surgery.
