RESUMEN
PURPOSE: The clinical influence of knot-tying or knotless anchor systems for the arthroscopic repair of SLAP lesions (superior labrum lesion from anterior to posterior) remain unclear. MATERIALS AND METHODS: In a retrospective cohort analysis, 61 of 78 (78.2%) patients with isolated symptomatic SLAP II lesions were examined with a minimum of 24 months after arthroscopic SLAP repair compared to a control group: 28 patients with knot-tying anchors (group I, G1; 28.95 ± 9.48 years, 23 male/5 female), 33 with knotless anchors (group II, G2; 31 ± 10.09 years, 26 male/7 female) and 140 healthy volunteers (group III, G3; 30.9 ± 8.9 years, 109 male/31 female). The clinical assessment included an examination and estimated parameters of ADL (activities of daily living), the CS (Constant score), ASES (American Shoulder and Elbow score), DASH (disability of arm-shoulder hand) and the RS (Rowe score). RESULTS: The ROM analysis recorded no significant differences for the external rotation in 0° abduction (G1 63.75° ± 15.55° versus = vs G2 65.30° ± 18.15°; pERG1 vs G2 = 0.72). The clinical outcomes revealed significantly decreased pain status in G1 for the O'brien test and in G2 for the Palm-up test, whereas Yergason test showed similar pain levels (pO'brien = 0.03; ppalm up = 0.02; pyergason > 0.5). The pulley associated rotator cuff tests revealed a significantly inferior force status in G2 compared to G1 (plift-off = 0.005, pJobe = 0.02) whereas the further rotator cuff assessments were equal. In general, the intervention group showed increased pain level and functional deficits compared to the G3. The score analysis detected no significant differences with PCSG1 vs G2, PASESG1 vs G2, PDASHG1 vs G2 and PRSG1 vs G2 all > 0.05 and significant impairments compared to G3 in all scores pG1/G2 vs G3 < 0.05 (CSG1 = 88.28 ± 14.42, CSG2=92.73 ± 9.24, CSG3 = 96.2 ± 4.96; ASESG1 = 81.10 ± 21.69, ASESG2 = 85.35 ± 17.12, ASESG3 = 94.95 ± 10.39,; DASHG1= 35.75 ± 13.44, DASHG2 = 36.03 ± 17.55, DASHG3 = 27.13 ± 6.52; RSG1 = 90.71 ± 9.88, RSG2 = 88.33 ± 11.22, RSG3= 92.96 ± 11.27). CONCLUSIONS: The clinical assessment revealed for both anchor systems similar outcomes but showed general underestimated impairments after the SLAP repair surgery compared to the healthy control. The clinical status only marginally differed between both techniques, wherefore the present assessment of ADL allowed no recommendation of one of these two specific surgery technique for SLAP repair.

PURPOSE: Traumatic high-grade acromioclavicular joint (ACJ) separations can be surgically stabilized by numerous anatomic and non-anatomic procedures. The return to sport (Maffe et al. in Am J Sports Med 23:93-98, 1995] and remaining sport-associated impairments after acute ACJ stabilization has not yet been investigated. METHODS: 73 consecutive athletes with acute high-grade ACJ separation were prospectively assigned into two groups (64.4% randomized, 35.6% intention-to-treat): open clavicular hook plate (cHP) implantation (GI) or arthroscopically assisted double double-suture-button (dDSB) implantation (GII). Patients were analyzed using shoulder sport-specific measurement tools for sport ability (ASOSS), sport activity (SSAS), and numerical analog scales: NASpain during sport, NASshoulder function in sport, and NASre-achievement of sport level. Four points of examination were established: preoperative evaluation (FU0) and first postoperative follow-up (FU1) at 6 months; FU2 at 12 months; and FU3 at 24 months after surgery. The control group (GIII) consisted of 140 healthy athletes without anamnesis of prior macro-injury or surgery. RESULTS: After surgical stabilization, 29 of 35 athletes in GI (82.9%; 38.6 ± 9.9 years) and 32 of 38 in GII (82.9%; 38.6 ± 9.9 years) were followed up for 24 months (FU3) (loss 17.8%). All operated athletes showed significantly increased scores compared to FU0 (p < 0.05). Compared to GI, GII showed significantly superior outcome data for sporting ability as well as for NASre-achievement of sport level (p < 0.05). While GII re-achieved GIII-comparable SSAS and ASOSS levels, GI remained at a significantly inferior level. Athletes after ACJ injury of Rockwood grade IV/V and overhead athletes benefited significantly from the dDSB procedure. CONCLUSION: The dDSB procedure enabled significantly superior sport-specific outcomes compared to the cHP procedure. Athletes after dDSB surgeries re-achieved the sporting ability and the sport activity levels of healthy athletes, whereas athletes after cHP implantation remained at significantly inferior levels. The more extensive dDSB procedure and the more restrictive rehabilitation are recommended for treatment of acute high-grade ACJ separations of functionally high-demanding athletes.

PURPOSE: The restoration of the labrum complex and the influence on secondary osteoarthritis after arthroscopic Bankart repair on magnetic resonance imaging (MRI) remain unclear. METHODS: Twenty-one patients were retrospectively followed after unilateral primary arthroscopic Bankart repair with knot-tying suture anchors (8.8 ± 2.5 years after surgery, age 25.3 ± 6.3 years). Bilateral structural MRI was performed to assess labrum-glenoid restoration by measurements of the labrum slope angle, height index, and labrum interior morphology according to the Randelli classification. Osteoarthritic status was bilaterally assessed by a modified assessment based on the Samilson-Prieto classification. RESULTS: MRI assessment revealed full labrum-glenoid complex restoration with equivalent parameters for anterior slope angle (mean ± SD: 21.3° ± 2.6° after Bankart repair vs. 21.9° ± 2.6° control) and height index (2.34 ± 0.4 vs. 2.44 ± 0.4), as well as the inferior slope angle (23.1° ± 2.9° vs. 23.3° ± 2.1°) and height index (2.21 ± 0.3 vs. 2.21 ± 0.3) (all n.s.). The labrum morphology showed only for the anterior labrum significant alterations (1.4 ± 0.9 vs. 0.6 ± 0.7, p < 0.05), the inferior labrum occurred similarly (1.3 ± 0.8 vs. 0.8 ± 0.5, n.s.). Osteoarthritic changes were significantly increased after Bankart repair compared to the uninjured shoulder (4.8 ± 5.1 mm vs. 2.5 ± 1.0 mm; p < 0.05), with a significant correlation of osteoarthritis status between both shoulders (p < 0.05). Scores generally decreased after Bankart repair (constant 84.6 ± 9.5 vs. 94.5 ± 4.9 control, p < 0.05; Rowe 84.5 ± 6.5 vs. 96.2 ± 4.2, p < 0.05; Walch-Duplay 82.4 ± 7.0 vs. 94.3 ± 4.0, p < 0.05) with a strong correlation with osteoarthritis status (p < 0.05). CONCLUSIONS: Arthroscopic Bankart repair enabled good clinical outcomes and complete quantitative labrum restoration parameters. Next to several well-known parameters, secondary osteoarthritis after arthroscopic Bankart repair significantly correlated with osteoarthritic status of the uninjured contralateral shoulder but was not influenced by quantitative labrum restoration. The recommendation for arthroscopic Bankart repair should be based on clinical parameters and not on prevention of secondary osteoarthritis. STUDY DESIGN: Case series. LEVEL OF EVIDENCE: IV.

INTRODUCTION: Arthroscopic repair is one option for the surgical treatment of type II superior labrum tears from anterior to posterior (SLAP) lesions in athletes' shoulders. MATERIALS AND METHODS: Sixty-one of 78 (78.2%) athletes were retrospectively examined after isolated arthroscopic SLAP repair (group 1/G1: 28x knot-tying anchors; group 2/G2: 33 knotless anchors; follow-up 24 months) and compared to two specific, separate matched volunteer athlete control groups (group 3/G3: 28 athletes matched to G1; group 4/G4: 33 athletes matched to G2). The assessment of G1-4 included numerical analogue scales (NASs: 1-15 scales) and the Athletic Shoulder Outcome Scoring System (ASOSS) score, and the Shoulder Sport Activity Score (SSAS). The preinjury status (FU-1), the status before surgery (FU0), and at follow-up (FU1) were assessed. RESULTS: High external rotation at abduction (hER) was significantly worse in G1 than G2 (FU1: G1, 86.6° ± 7.7° versus = vs G2, 91.1° ± 10.7°; p = 0.03). The ASOSS and SSAS revealed significant impairment in G1-2 compared to G3-4 (ASOSS FU1: 83.9 ± 19.9 G1 vs 94.6 ± 7.7 G3; p = 0.002 and 80.3 ± 17.7 G2 vs 91.8 ± 9.1 G4; p = 0.002; SSAS 5.9 ± 2.7 G1 vs 6.9 ± 1.8 G3; p = 0.02 and 6.3 ± 2.5 G2 vs 7.4 ± 1.4 G4; p = 0.06), with 17-20% loss on ASOSS and 23-25% deficits on SSAS. The NAS analysis detected for pain (4 ± 3.5 vs 3.2 ± 2.6), satisfaction (2 ± 0.8 vs 1.8 ± 0.9), reduction of function (4.6 ± 3.9 vs 3.9 ± 3.8) and proficiency (9.6 ± 4.7 vs 10.9 ± 3.9) similar impairments in G1-2 (p > 0.05) and better results in G3 and G4 (all p < 0.001). CONCLUSIONS: After SLAP repair, athletes showed underestimated impairment of shoulder sport resumption and proficiency with high rates of shoulder sports cessation. The present data favor the knotless fixation technique, because this fixation technique allowed bilaterally equivalent ranges of motions. The uninjured shoulder athletes also showed functional deficits with significant shoulder sport impairments, which must be considered in outcome analysis and for the rehabilitation program.
