Abstract
INTRODUCTION The purpose of this prospective study was to report the outcomes of two different methods in CC and AC reconstruction for the treatment of AC separation using a tendon graft and knot-hiding titanium clavicular implant. MATERIALS AND METHODS Twenty-seven patients with Rockwood grade III and V acromioclavicular (AC) separations were randomized into two groups. The primary outcome was whether taking the tendon graft through the coracoid risked a fracture. The following were secondary outcomes: follow-up of clavicular wound healing and Nottingham Clavicle score, Constant score, and Simple Shoulder Test results obtained preoperatively and 24 months postoperatively. The anteroposterior radiographic change between the clavicular and coracoid cortexes and the clavicular tunnel diameter was measured postoperatively and 24 months postoperatively. General patient satisfaction with the outcome (poor, fair, good, or excellent) was assessed 2 years postoperatively. RESULTS No coracoid fractures were detected. No issues in clavicular wound healing were detected. The mean Nottingham Clavicle score increased from a preoperative mean of 42.42 ± 13.42 to 95.31 ± 14.20 (P < 0.00). The Constant score increased from a preoperative mean of 50.81 ± 17.77 to 96.42 ± 11.51 (P < 0.001). The Simple Shoulder Test score increased from a preoperative mean of 7.50 ± 2.45 to 11.77 ± 1.18 (P < 0.001). The changes were significant. The coracoclavicular distance increased from 11.88 ± 4.00 to 14.19 ± 4.71 mm (P = 0.001), which was significant. The clavicular drill hole diameter increased from 5.5 to a mean of 8.00 ± 0.75 mm. General patient satisfaction was excellent. CONCLUSIONS There were no significant differences between the two groups. There were no implant related complications in the clavicular wound healing. The results support the notion that good results are achieved by reconstructing both the CC and AC ligaments with a tendon graft.

Velasquez Garcia A, Franco Abache A, Ingala Martini L. Clavicular tunnel widening after coracoclavicular stabilization surgery: a systematic review and meta-analysis. J Shoulder Elbow Surg 2024; 33:738-755. [PMID: 37977250 DOI: 10.1016/j.jse.2023.09.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 09/10/2023] [Accepted: 09/25/2023] [Indexed: 11/19/2023]
Abstract
BACKGROUND This systematic review and meta-analysis aimed to (1) estimate the prevalence of clavicular tunnel widening (TW) after coracoclavicular stabilization surgery and its risk factors and (2) assess whether TW is correlated with clavicle fracture or loss of reduction of the acromioclavicular joint (ACJ). METHODS In January 2023, 3 electronic databases were searched to collect data on postoperative clavicular TW, its prevalence, magnitude, and correlation with fracture and ACJ loss of reduction. Studies were classified according to the time of surgical intervention, and the clavicular tunnels were categorized by their anatomic location. Mean differences were calculated using a DerSimonian-Laird random-effects model, while binomial outcomes were pooled using the Freeman-Tukey double arcsine transformation. Univariate and multivariate meta-regression analyses were performed to determine the effect of several variables on the proportion of cases with TW. RESULTS Fifteen studies (418 shoulders) were included. At the final follow-up, evidence of clavicular TW was found in 70% (95% confidence interval [CI]: 70%-87%; I2 = 89%) of 221 shoulders. Surgeries in acute cases had a lower prevalence of TW (52%) compared to chronic cases (71%) (P < .001). Significant TW was found in the central tunnel (3.2 mm; 95% CI: 1.8-4.6 mm; P < .001; I2 = 72%) for acute injuries and in the medial (1.2 mm; 95% CI: 0.7-1.7 mm; P < .001; I2 = 77%) and lateral (1.5 mm; 95% CI: 0.7-2.3 mm; P < .001; I2 = 77%) tunnels for chronic cases. Single central-tunnel techniques were positively associated with the prevalence of TW (P = .046), while biotenodesis screw fixation was associated with a lower prevalence (P = .004) in chronic cases. Reconstruction of the ACJ ligament complex with tendon grafts or sutures was associated with a higher prevalence of TW (P < .001). Drill sizes between 2.5 and 5 mm were significantly associated with a lower prevalence of TW, regardless of injury chronicity (P = .012). No correlation was found between TW and the loss of ACJ reduction or clavicle fractures. CONCLUSIONS This systematic review and meta-analysis explored TW occurrence following coracoclavicular stabilization surgery. TW was observed in 70% of patients at final follow-up, with a higher prevalence in chronic than in acute cases. Modifiable surgical variables, such as single-tunnel tendon graft constructs for acute or chronic injuries and knotted graft procedures for chronic injuries, were significantly associated with TW. Furthermore, the prevalence of TW increased with concomitant surgical treatment of the ACJ ligament complex, and decreased with drill sizes between 2.5 and 5 mm, regardless of lesion chronicity. These surgical variables should be considered when establishing transosseous tunnels for coracoclavicular stabilization. Clavicle fractures and TW mechanisms require further investigation.

Abstract
PURPOSE Biomechanical evaluation of three different suture button devices used in acromioclavicular joint repair and analysis of their effect on post-testing tunnel widening. METHODS Eighteen human shoulder girdles were assigned into three groups with a similar mean bone mineral density. Three different single-tunnel acromioclavicular repair devices were tested: (1) AC TightRope® with FiberWire; (2) AC Dog Bone™ Button with FiberTape; (3) Low Profile AC Repair System. Biomechanical testing was performed simulating the complex movement of the distal clavicle as follows. A vertical load of 80 N was applied continuously. The rotation of the clavicle about its long axis was set at 10° anterior and 30° posterior for 2500 cycles at 0.25 Hz. The horizontal translation of the clavicle was set at 6 mm medial and 6 mm lateral for 10,000 cycles at 1 Hz. The coracoclavicular distance was measured before and after testing. After testing, each sample underwent micro-CT analysis. Following 3D reconstruction, the area of the bone tunnels was measured at five defined cross sections. RESULTS In TightRope® and Dog Bone™ groups, all samples completed testing, whereas in the Low Profile group, three out of six samples showed system failure. The mean absolute difference of coracoclavicular distance after testing was significantly greater in the Low Profile group compared to TightRope® and Dog Bone™ groups (4.3 ± 1.3 mm vs 1.9 ± 0.7 mm vs 1.9 ± 0.8 mm; p = 0.001). Micro-CT analysis of the specimens demonstrated significant tunnel widening in the inferior clavicular and superior coracoid regions in all three groups (p < 0.05). CONCLUSION Significant tunnel widening can be observed for all devices and is primarily found in the inferior parts of the clavicle and superior parts of the coracoid. The Low Profile AC Repair System showed inferior biomechanical properties compared to the AC TightRope® and AC Dog Bone™ devices. Therefore, clinicians should carefully select the type of acromioclavicular repair device used and need to consider tunnel widening as a complication.

Abstract
Background Acromioclavicular (AC) joint separation is a common cause of shoulder injury among athletes. High-grade injuries may require operative fixation, and comprehensive return-to-play guidelines have not yet been established. The purpose of this study was to summarize criteria for return to play after operative management of AC joint separation. Methods A systematic review of the literature was performed from January 1999 to April 2020 to evaluate clinical evidence regarding criteria for return to play after operative management of isolated AC joint separation. Results Sixty-three studies with at least 1 explicitly stated return-to-play criterion were identified out of an initial database search of 1253 published articles. Eight separate categories of return-to-play criteria were identified, the most common of which was time from surgery (95.2%). Return-to-play timelines ranged from 2 to 12 months, the most common timeline being 6 months (37.8%). Only 4 (6.3%) studies used conditional criteria to guide return to play, which included range of motion, strength, clinical stability, radiographic stability, functional assessment, safety assessment, and hardware removal. Conclusion Most published studies use only time-based criteria for return to play after surgery for AC joint separation, and only a small number of studies use additional subjective or objective criteria. While this systematic review helps provide a foundation for developing a comprehensive return-to-play checklist, further investigation is needed to establish safe and effective guidelines that will enable athletes to safely return to sport and minimize the recurrence of injury.

Abstract
PURPOSE To quantify the effect on strength of semitendinosus (ST) graft harvest by comparing isokinetic and isometric muscle strength. METHODS A cohort of 140 patients underwent anterior cruciate ligament (ACL) reconstruction (ACLR) and were randomized to ipsilateral or contralateral ST graft harvest. Isokinetic and isometric muscle strength testing using a dynamometer were collected for the operated and non-operated leg. Patients were assessed pre-surgery and at 6, 12 and 24 months after reconstruction. RESULTS ST graft harvest reduced isokinetic flexion muscle strength for 6 months. At 12 months follow up there was no significant difference between the two groups and they were all stronger than pre-injury. No other significant differences were found in any primary or secondary outcome measurements. CONCLUSION Solitary ST graft harvest does not appear to result in a permanent reduced isometric or isokinetic quadriceps muscle strength on the side where the graft is harvested. A reduction in hamstring muscle strength of less than 10% can be seen at short-term follow-up with full recovery by 12 months. Most patients report little or no donor site pain. Given these findings, ST autograft is an alternative graft choice that could be used for various reconstructions in terms of donor site morbidity. LEVEL OF EVIDENCE Level II.

Abstract
There are numerous described techniques for surgical management of high-grade acromioclavicular (AC) joint injuries, and the associated clinical outcomes can be quite variable. Contemporary techniques are typically directed at anatomic reconstruction of the coracoclavicular (CC) ligaments through either an arthroscopy-assisted or an open approach. Most patients treated with acute surgery improve, whereas in chronic cases, the majority improve, but a significant number have persistent recurrent deformity due to loss of anatomic reduction. In addition, whether acute or chronic, over one quarter of patients do not have a PASS (patient acceptable symptomatic state). Of interest, PASS may not primarily be related to the final deformity in terms of coracoclavicular distance, and investigation is still required in terms of the effect of anteroposterior or rotational instability of the AC joint after injury and surgery. Finally, PASS values for AC separation are not well established, resulting in a current limitation of the strength of applying threshold values to this pathology.

Abstract
BACKGROUND Coracoclavicular (CC) ligament reconstruction is a commonly performed procedure for high-grade acromioclavicular (AC) joint separations. Although distal clavicle and coracoid process fractures represent potential complications, they have been described in only case reports and small case series. PURPOSE To identify the incidence and characteristics of clavicle and coracoid fractures after CC ligament reconstruction. STUDY DESIGN Case series; Level of evidence, 4. METHODS The US Military Health System Data Repository was queried for patients with a Current Procedural Terminology code for CC ligament repair or reconstruction between October 2013 and March 2020. The electronic health records, including patient characteristics, radiographs, operative reports, and clinical notes, were evaluated for intraoperative or postoperative clavicle or coracoid fractures. Initial operative technique, fracture management, and subsequent clinical outcomes were reviewed for these patients. RESULTS A total of 896 primary CC ligament repairs or reconstructions were performed during the study period. There were 21 postoperative fractures and 1 intraoperative fracture in 20 patients. Of these fractures, 12 involved the coracoid and 10 involved the clavicle. The overall incidence of fracture was 3.81 fractures per 1000 person-years. In 5 patients who sustained a fracture, bone tunnels were not drilled in the fractured bone during the index procedure. A total of 17 fractures were ultimately treated operatively, whereas 5 fractures had nonoperative management. Of the 16 active-duty servicemembers who sustained intraoperative or postoperative fractures, 11 were unable to return to full military duty after their fracture care. CONCLUSION Fracture of the distal clavicle or coracoid process after CC ligament repair or reconstruction is a rare but serious complication that can occur independent of bone tunnels created during the index procedure. Fractures associated with CC ligament procedures occurred at a rate of 2.46 per 100 cases. Most patients were ultimately treated surgically with open reduction and internal fixation or revision CC ligament reconstruction. Although the majority of patients with intraoperative or postoperative fractures regained full range of motion, complications such as anterior shoulder pain, AC joint asymmetry, and activity-related weakness were common sequelae resulting in physical limitations and separation from military service.

Abstract
The purpose of this study is to introduce an arthroscopy-assisted technique to treat chronic acromioclavicular (AC) dislocation. The method involves reconstructing both the coracoclavicular (CC) and AC ligaments in a practical and reliable way using a semi-tendon graft and knot-hiding implants. In the CC reconstruction, the anterior graft limb replaces the trapezoid ligament, whereas the dorsal limb is wrapped around the dorsal edge of the clavicle to reconstruct the conoid ligament. One 5.5-mm drill hole is needed in the clavicle since the semitendinosus graft and the interconnecting supportive suture share the same drill hole. A 2.4-mm drill hole through the coracoid is needed for the interconnective suture. The technique uses knot-hiding titanium implants that are designed to be used with a tendon graft. After finishing the arthroscopic CC reconstruction, the dorsal end of the tendon graft is openly taken over the AC joint to openly reconstruct the superior AC ligament. The AC capsule is then plicated over the reconstruction. The arthroscopic part of the reconstruction is not technically difficult for an experienced arthroscopic shoulder surgeon. For success, it is essential to achieve a tension-free reduction of the distal clavicle and to provide sufficient recovery time postoperatively.
