Objectives: There remains a paucity of data describing the efficacy of non-operative treatment following an index anterior instability event. The purpose of this study was to describe the long-term outcomes of non-operative treatment following index anterior instability event, define the success rate of initial non-operative treatment for anterior shoulder instability, and describe factors that predict conversion to surgery after initial non-operative management to help guide surgical decision making in these patients. Methods: An established geographic database was utilized to identify patients under the age of 40 treated for anterior shoulder instability between 1994 and 2016. Patient demographics, comorbidities, injury characteristics, instability history, activity level, x-rays, advanced imaging, treatment course, and outcomes were evaluated. Patients treated non-operatively for the first 6 months following index instability event were analyzed to determine long-term outcomes, success rate of continued non-operative treatment, and factors associated with conversion to surgery. Results: 739 patients met criteria with an average follow-up of 190 months (range 0.13 to 490 months). Average age was 23.8, mean BMI was 25.6, 9.1% had a history of hyperlaxity, and 83.9% of instability events were due to trauma. 29.7% of patients had a Hill-Sachs lesion on index x-ray, and 6.3% had a bony Bankart. 198 shoulders went on to operative treatment (26.8%) with a mean time to surgery of 62.7 months following initial instability event. At final follow-up, 24.0% reported mild pain, 6.2% as moderate, 0.2% as severe. 13.8% of patients had evidence of glenohumeral arthritis on final follow-up x-rays compared to 1.6% on initial radiographs. Factors associated with conversion to surgery included 2 or more dislocations prior to first clinical evaluation (OR=1.75, p<0.001), labor intense occupation (OR=1.49, p=0.031), Hill Sachs lesion on index x-ray (OR=1.31, p=0.034), and MRI findings including: anteroinferior labral tear (OR=2.15, p<0.001), posteroinferior labral tear (OR=1.38, p=0.049), SLAP tear (OR=1.29, p=0.054), Hill-Sachs lesion (OR=1.85, p<0.001), and glenohumeral cartilage injury (OR=1.26, p=0.041). Conclusion: The majority of patients less than 40 can be definitively treated non-operatively after an initial 6 month episode of non-operative treatment. A small proportion will report pain over the long-term and/or develop glenohumeral arthritis. Multiple factors upon initial evaluation were associated with future conversion to surgery including: increasing number of prior instability events, occupation, and degree of soft tissue injury on MRI.

Recurrent Anterior Shoulder Instability

Background: Recent studies have demonstrated equivalent short-term results when comparing arthroscopic versus open anterior shoulder stabilization. However, none have evaluated the long-term clinical outcomes of patients after arthroscopic or open anterior shoulder stabilization, with inclusion of an assessment of preoperative glenoid tracking. Purpose: To compare long-term clinical outcomes of patients with recurrent anterior shoulder instability randomized to open and arthroscopic stabilization groups. Additionally, preoperative magnetic resonance imaging (MRI) studies were used to assess whether the shoulders were “on-track” or “off-track” to ascertain a prediction of increased failure risk. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A consecutive series of 64 patients with recurrent anterior shoulder instability were randomized to receive either arthroscopic or open stabilization by a single surgeon. Follow-up assessments were performed at minimum 15-year follow-up using established postoperative evaluations. Clinical failure was defined as any recurrent dislocation postoperatively or subjective instability. Preoperative MRI scans were obtained to calculate the glenoid track and designate shoulders as on-track or off-track. These results were then correlated with the patients’ clinical results at their latest follow-up. Results: Of 64 patients, 60 (28 arthroscopic and 32 open) were contacted or examined for follow-up (range, 15-17 years). The mean age at the time of surgery was 25 years (range, 19-42 years), while the mean age at the time of this assessment was 40 years (range, 34-57 years). The rates of arthroscopic and open long-term failure were 14.3% (4/28) and 12.5% (4/32), respectively. There were no differences in subjective shoulder outcome scores between the treatment groups. Of the 56 shoulders, with available MRI studies, 8 (14.3%) were determined to be off-track. Of these 8 shoulders, there were 2 surgical failures (25.0%; 1 treated arthroscopically, 1 treated open). In the on-track group, 6 of 48 had failed surgery (12.5%; 3 open, 3 arthroscopic [ P = .280]). Conclusion: Long-term clinical outcomes were comparable at 15 years postoperatively between the arthroscopic and open stabilization groups. The presence of an off-track lesion may be associated with a higher rate of recurrent instability in both cohorts at long-term follow-up; however, this study was underpowered to verify this situation.

Abstract Purpose Age at primary dislocation, recurrence, and glenoid bone loss are associated with development of osteoarthritis (OA). However, an overview of OA following traumatic anterior shoulder instability is lacking and it is unclear to what degree type of surgery is associated with development of OA in comparison to non-operative treatment. The aim of this study was to determine the degree of OA at long-term follow-up after non-operative and operative treatments for patients with anterior shoulder instability. Surgery is indicated when patients experience recurrence and this is associated with OA; therefore, it was hypothesized that shoulders show a higher proportion or degree of OA following operative treatment compared to non-operative treatment. Methods A literature search was performed in the PubMed/Medline, EMBASE, and Cochrane databases. Articles reporting the degree of OA that was assessed with the Samilson–Prieto or Buscayret OA classification method after non-operative and operative treatment for anterior shoulder instability with a minimum of 5 years follow-up were included. Results Thirty-six articles met the eligibility criteria of which 1 reported the degree of OA for non-operative treatment and 35 reported the degree of OA for 9 different operative procedures. A total of 1832 patients (1854 shoulders) were included. OA proportions of non-operative and operative treatments are similar at any point of follow-up. The Latarjet procedure showed a lower degree of OA compared to non-operative treatment and the other operative procedures, except for the Bristow procedure and Rockwood capsular shift. The meta-analyses showed comparable development of OA over time among the treatment options. An increase in OA proportion was observed when comparing the injured to the contralateral shoulder. However, a difference between the operative subgroups was observed in neither analysis. Conclusion Non-operative and operative treatments show similar OA proportions at any point of follow-up. The hypothesis that shoulders showed a higher proportion or degree of OA following operative treatment compared to non-operative treatment is not supported by the data. Operative treatment according to the Latarjet procedure results in a lower degree of OA compared to other treatments, including non-operative treatment. Level of evidence IV.

Capsulolabral Reconstruction

Background: Recent studies have reported high rates of recurrence of shoulder instability in patients with glenoid bone defects greater than 20% after capsulolabral reconstruction. The purpose of the present study was to evaluate the failure rate of arthroscopic capsulolabral reconstruction for the treatment of anterior instability in the presence of glenoid bone deficits >20%. Methods: Retrospective analyses were conducted among cases with anterior shoulder instability and glenoid bone defects of >20% that were treated by arthroscopic capsulolabral reconstruction with a minimum 2-year follow-up (30 cases). We included the following variables: age, bone defect size, instability severity index score (ISIS), on-/off-track assessment, incidence recurrent instability, and return to sports. Results: The mean glenoid bone defect size was 25.8% ± 4.2% (range, 20.4%–37.2%), and 18 cases (60%) had defects of >25%. Bony Bankart lesions were identified in 11 cases (36.7%). Eleven cases (36.7%) had ISIS scores >6 points and 21 cases (70%) had off-track lesions. No cases of recurrent instability were identified over a mean follow-up of 39.9 months (range, 24–86 months), but a sense of subluxation was reported by three patients. Return to sports at the preinjury level was possible in 24 cases (80%), and the average satisfaction rating was 92%. Conclusions: Arthroscopic soft tissue reconstruction was successful for treating anterior shoulder instability among patients with glenoid bone defects >20%, even enabling return to sports. Future studies should focus on determining the range of bone defect sizes that can be successfully managed by soft tissue repair.

Biomechanical Effect

Background: Individual constitutional differences in glenoid shape and bone remodeling require a patient-specific and longitudinal approach to evaluate the biomechanical effects of glenoid bone grafting in patients with anterior shoulder instability. Purpose: To quantify the longitudinal, in vivo, biomechanical effects of bone grafting, bone graft remodeling, and glenoid shape in patients with anterior shoulder instability by means of patient-specific finite element models. Study Design: Descriptive laboratory study. Methods: In total, 25 shoulders of 24 patients with anterior shoulder instability and anterior glenoid bone loss underwent an arthroscopic iliac crest bone graft transfer (ICBGT) procedure with either autologous or allogenic bone. Patient-specific finite element simulations based on preoperative, postoperative, and follow-up computed tomography scans were used to quantify the bone-mediated stability ratio (SR) and the distance to dislocation. Additionally, the relationship between glenoid morphological parameters and the SR was assessed. Results: The ICBGT procedure significantly increased the SR and distance to dislocation in the 2-, 3-, and 4-o’clock directions immediately after the surgical intervention ( P < .01) in both the autograft and the allograft groups. Although the SR and distance to dislocation decreased subsequently, autografts showed long-term effects on SR and dislocation distance in the 3-o’clock direction ( P < .01) and on SR in the 4-o’clock direction ( P < .01). Allografts showed no significant effect on SR and dislocation distance in long-term follow-up ( P > .05). Overall, glenoid retroversion as well as cavity depth predicted stability in all 4 dislocation directions, with glenoid cavity depth showing the highest correlation coefficients ( R = 0.71, 0.8, 0.73, and 0.7 for 2-, 3-, 4-, and 5-o’clock, respectively). Conclusion: The autologous ICBGT procedure biomechanically improved anterior shoulder stability in long-term follow-up, whereas the use of allografts did not show any bone-mediated biomechanical effect at follow-up due to resorption. Furthermore, in addition to measurements of defect extent, the glenoid depth and version seem to be useful parameters to determine the biomechanical effect and need for glenoid bone grafting in patients with shoulder instability. Clinical Relevance: This study proposes the use of autologous bone grafts for a successful long-term stabilization effect. Additionally, this study proposes additional glenoid morphological measures to predict shoulder stability.

Category: Arthroscopy; Ankle Introduction/Purpose: Arthroscopic bone marrow stimulation (BMS) has been considered as the 1st-line treatment for osteochondral lesions of the talus (OLT) with its simplicity, cost-effectiveness, low complication rate and successful clinical results in numerous studies. However, there were few studies which had investigated long-term clinical outcomes about the arthroscopic BMS. The purpose of this study is to evaluate the long-term outcomes of arthroscopic BMS for OLT and to identify prognostic factors that affect the outcomes. Methods: A retrospective analysis was performed for 202 ankles (189 patients) who underwent arthroscopic BMS as a primary surgery for the OLT between January 2001 and December 2008 with more than 10 years of follow-up. Visual analog scale (VAS) and American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scales, Foot and Ankle Outcome Score (FAOS) were assessed as clinical outcomes and re-operation data were collected. The clinical scores were compared along the stream of time. Kaplan-Meier plot and log rank test showed survival outcomes of OLT in the long-term follow-up. Factors associated with revision surgery were evaluated with multivariate Cox proportional hazard regression model. Results: The VAS scales were improved from 7.11 +- 1.73 (preoperatively) to 1.51 +- 1.61 (3 to 6 years after BMS), and 2.00 +- 1.67 (over 10 years after BMS) (P < 0.001). Also the AOFAS ankle-hindfoot scale were also improved from 58.39 +- 13.7373 (preoperatively) to 85.85 +- 10.31 (3 to 6 years after BMS), and 82.56 +- 11.62 (over 10 years after BMS) (P < 0.001). FAOS at final follow-up was compatible with those of other literatures with short- and mid-term follow-up. Re-operation rate was 5.94 % (12 / 202 ankles). According to multivariate regression analysis, significant factors associated with the revision surgery were large- size (greater than 150mm2) OLT (P = 0.009) and body mass index greater than 25 kg/m2 (P = 0.014). Conclusion:: Arthroscopic bone marrow stimulation is an effective and reliable operative procedure for the primary treatment of osteochondral lesions of the talus with favorable long-term outcomes at a mean follow-up of 13.9 years. Therefore, we recommend this procedure for the 1st-line treatment of the OLT. Success of arthroscopic BMS depends on the size of the OLT and the body mass index of patients.

Results of 45 ankle joint replacements performed during the period from 1998 to 2008 have been analyzed. Cementless original implants were applied in 6 (13.3%), «Link S.T.A.R.» implants - in 26 (57.8%) and «DePuy Mobility TM» implants - in 13 (28.9%) cases. Mean follow-up made up 3 years (from several months to 10 years). For the evaluation of long-term outcomes the data from patients questionnaires (prior to, 6 months after operation and at the time of last examination) and X-ray results were used. Early complications, i.e. fracture of lateral malleolus, was noted in 4 patients. Long-term complications, i.e. dislocation of tibial component, were observed in 2 patients. In 2 patients the development of infectious complications required implant removal followed by arthrodesis. In 91% of cases the results were assessed as satisfactory and good by Kitaoka scale.
