ABSTRACT
BACKGROUND: Standard open acromioclavicular (AC) stabilization is associated with increased postoperative complications including deltoid injury, infection, tunnel complications, loss of reduction, and wound/cosmetic concerns. Arthroscopy may offer superior visualization and advantages that limit these risks. The aim of this prospective non-randomized study is to evaluate advantages and long-term reliability of arthroscopic AC stabilization. METHODS: Thirty-two patients with acute grade III, IV and V AC dislocations underwent arthroscopic AC reconstruction with long-term assessment by clinical AC examination, Simple Shoulder Test, American Shoulder and Elbow Surgeons scores, visual analog scale, Specific AC Score and Quick Disabilities of the Arm, Shoulder and Hand scores. Radiographs verified conservation of initial reduction and presence of coracoclavicular (CC) ossifications. Complications, revision rate, and satisfaction were assessed and compared to the literature. RESULTS: Mean follow-up time was 67.6 months. All clinical outcome scores improved and differences were statistically significant (P<0.001). Initial postoperative radiographs consistently showed complete reduction. Two patients experienced relapse to grade II AC dislocation without clinical implications. In total, 71.8% showed CC ossifications without functional impairment, and in 31.3% concomitant injuries were observed. Reintervention rate was 9.4%, and 96.9% of patients were satisfied with procedure outcomes. CONCLUSIONS: Arthroscopic stabilization for acute AC joint dislocations offers satisfactory clinical and radiographic outcomes, and our results show that the arthroscopic technique is reliable in the long run. We report better reduction in maintenance, fewer complications, and similar reoperation rates compared to other techniques. Level of evidence: III.
ABSTRACT
BACKGROUND: In patients with symptomatic trapeziometacarpal (TMC) joint arthritis resistant to conservative treatment, surgical treatment can be advised. One of the many surgical treatment options is TMC arthroplasty. The Arpe prosthesis is one example of these TMC arthroplasties. METHODS: This retrospective study evaluated patients who underwent TMC arthroplasty with the Arpe prosthesis after a minimum of 15 years of follow-up. Clinical, radiologic, and qualitative outcomes were assessed for 43 Arpe arthroplasties in 41 patients, of whom 2 had bilateral arthroplasties. The female to male ratio was 39:4. The mean follow-up time was 197 months (range = 180-225). RESULTS: The cumulative survival rate after a mean of 16.5 years was 84%. Seven failures (16%) were registered, of which 5 during the first 3 years after primary surgery. All patients were successfully converted to a trapeziectomy. Quick Disabilities of the Arm, Shoulder and Hand score improved with 44.9 points and visual analogue pain score with 97% and 91% at rest and during exercise, respectively. CONCLUSIONS: This series demonstrates that thumb arthroplasty is a reliable long-term solution for thumb base arthritis, with significant pain reduction and functional improvement, even after 15 years of follow-up.
ABSTRACT
BACKGROUND: The effect of the acromion index (AI) and critical shoulder angle (CSA) on the short-term healing rate after arthroscopic repair of the supraspinatus tendons is already known. Long-term effects have not been published yet. PURPOSE: Long-term evaluation of the effect of the AI and CSA on the postoperative healing rate and clinical results after arthroscopic repair of the supraspinatus tendon. METHODS: Patients with a symptomatic, single-tendon, full-thickness supraspinatus tear in whom nonoperative management had failed were treated with an arthroscopic repair. Preoperative radiographs were used to measure CSA and AI. Eight years postoperatively, magnetic resonance imaging (MRI) studies were performed and evaluated on repair integrity. Patient-reported outcome measurements were collected pre- and postoperatively. RESULTS: Thirty-one patients were evaluated 8 years postoperatively. The mean age at the time of surgery was 61 ± 9 years. MRI evaluation showed that 20 patients (65%) had an intact repair and 11 (35%) had a full-thickness retear. No significant differences were found between the intact and retear groups regarding age (P = .605), initial tear size (P = .485), retraction grade (P = .439), and all PROMs. The mean CSA for the intact group (33° ± 1°) was significantly lower than the CSA in the retear group (38° ± 1°; P = .004). Eighteen patients (58%) had a CSA ≥35°, and 9 (50%) among them had a retear and 9 (50%) had an intact repair.The mean AI for the intact group (0.72 ± 0.11) was significantly lower than the AI in the retear group (0.81 ± 0.08 ; P = .021). Seventeen patients (55%) had an AI ≥0.75, and 9 (53%) among them had a retear and 8 had an intact repair. If the AI was ≥0.75, the odds ratio of having a retear was 6.19 (P = .045). No progressive worsening of PROMs and clinical results could be demonstrated related to a higher CSA or AI during the entire follow-up. CONCLUSION: At long-term follow-up, a higher CSA has the tendency to have an increased rate of retear after arthroscopic supraspinatus tendon repair, but this was not significant. A higher AI significantly increased the retear risk. A higher CSA and AI did not impair the clinical results over time. An AI ≥0.75 was associated with a 6-fold increase in risk of retear after arthroscopic supraspinatus tendon repair.
ABSTRACT
This prospective randomized study compares the clinical results of immediate passive mobilization versus delayed mobilization in the rehabilitation of rotator cuff repair during the early postoperative period. The mobilization group (79 patients) received immediate daily passive mobilization. The immobilization group (51 patients) was immobilized for 4 weeks until physiotherapy was started. Passive range of motion was noted preoperatively, at 6 weeks and 4 months. Strength was measured preoperatively and at 4âmonths. Constant-Murley, Simple Shoulder Test, SPADI and UCLA scores were noted at baseline and at 4 months. Ultrasonography was performed at 6âweeks to exclude early failures of repair. We noted no significant difference between the two groups regarding range of motion at 6âweeks and range of motion, strength and functional outcome scores at 4 months. Ultrasound didn't show a difference in healing at 6 w in either of both groups. Both rehabilitation protocols seem applicable as well as safe in the early post-operative phase.
