Full arthroscopic vs. arthroscopically assisted posterosuperior latissimus dorsi tendon transfer for shoulders with failed and irreparable rotator cuff repair: matched case-control study. J Shoulder Elbow Surg 2024; 33:e198-e207. [PMID: 37769869 DOI: 10.1016/j.jse.2023.08.007] [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: 05/23/2023] [Revised: 08/02/2023] [Accepted: 08/06/2023] [Indexed: 10/03/2023]
Abstract
PURPOSE To compare clinical outcomes and complication rates of full arthroscopic latissimus dorsi tendon transfer (LDTT) vs. arthroscopically assisted LDTT, for the treatment of irreparable posterosuperior massive rotator cuff tears (mRCTs) in shoulders that had failed rotator cuff repair (RCR). METHODS We evaluated a continuous series of 191 patients who underwent LDTT over 4 consecutive years. A total of 107 patients did not have previous shoulder surgery, leaving 84 patients who had prior surgical procedures. All procedures performed over the first 2 years were arthroscopically assisted (n = 48), whereas all procedures performed over the last 2 years were full arthroscopic (n = 36). We noted all complications, as well as clinical scores and range of motion at ≥24 months. To enable direct comparison between the 2 techniques, propensity score matching was used to obtain 2 groups with equivalent age, sex, and follow-up. RESULTS Compared with the 48 patients who underwent arthroscopically assisted LDTT, the 36 patients who underwent full arthroscopic LDTT had comparable complications (13% vs. 11%) and conversions to RSA (8.3% vs. 5.6%). Propensity score matching resulted in 2 groups, each comprising 31 patients, which had similar outcomes in terms of clinical scores (except mobility component of Constant score, which was better following fully arthroscopic LDTT; P = .037) and range of motion at a minimum follow-up of 2 years. CONCLUSION At a minimum follow-up of 24 months, for the treatment of irreparable posterosuperior mRCTs in shoulders that had surgical antecedents, full arthroscopic LDTT had significantly better mobility component of the Constant score than arthroscopically assisted LDTT, although there were no significant differences in the other clinical or functional outcomes. Arthroscopically assisted LDTT and full arthroscopic LDTT had comparable rates of complications (8.3% vs. 13%) and conversion to RSA (5.6% vs. 8.3%).

Changes in in vivo three dimensional shoulder kinematics following latissimus dorsi tendon transfer for irreparable posterosuperior rotator cuff tears: A systematic review with meta-analysis. Clin Biomech (Bristol, Avon) 2024; 111:106148.

Abstract
BACKGROUND Latissimus dorsi transfer is a surgical procedure that can be used for treating posterosuperior rotator cuff tears. The procedure leads to improved shoulder function via alterations in the force vector couple around the shoulder. However, there is still no consensus on the biomechanical changes resulting from latissimus dorsi transfer. METHODS We performed a systematic review of the literature on 3D motion analysis studies evaluating the effects of latissimus dorsi transfer on shoulder kinematics. The available data on segment and joint range of motion was extracted and subject to meta-analysis when consistent across the studies. FINDINGS Our meta-analysis of pre- and post-operative studies revealed a significant improvement in forward flexion and abduction following latissimus dorsi transfer. When comparing the latissimus transferred shoulder with an uninjured contralateral side the meta-analysis found no significant difference in flexion range of motion, while abduction and external rotation was significantly higher in the uninjured shoulders. The overall risk of bias was moderate to high. High heterogeneity was found in the reporting of data, which limited our ability to perform a meta-analysis across the studies for all interest outcomes. INTERPRETATIONS Our findings suggest that latissimus dorsi transfer for posterosuperior rotator cuff tears effectively improves shoulder flexion and abduction. External rotation is also expected to improve but at inferior levels as compared to the unaffected side. However, the heterogeneity of the reported data on 3D motion analysis studies highlights the need for better standardization in research and reporting as to conclude the impact of different joints.

Abstract
PURPOSE Arthroscopic superior capsule reconstruction (SCR) with the long head of the biceps (LHBT) was performed to restore structural stability, force couple balance, and shoulder joint function. This study aimed to evaluate the functional outcomes of SCR using the LHBT over at least 24 months of follow-up. METHOD This retrospective study included 89 patients with massive rotator cuff tears who underwent SCR using the LHBT, met the inclusion criteria and underwent follow up for at least 24 months. The preoperative and postoperative shoulder range of motion (forward flexion, external rotation, and abduction), acromiohumeral interval (AHI), visual analog scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score and Constant-Murley score were obtained, and the tear size, and Goutallier and Hamada grades were also investigated. RESULTS Compared with those measured preoperatively, the range of motion, AHI, and VAS, Constant-Murley, and ASES scores were significantly improved immediately postoperatively (P < 0.001) and at the 6-month, 12-month, and final follow-ups (P < 0.001). At the last follow-up, the postoperative ASES score and Constant-Murley score increased from 42.8 ± 7.6 to 87.4 ± 6.1, and 42.3 ± 8.9 to 84.9 ± 10.7, respectively; with improvements of 51 ± 21.7 in forward flexion, 21.0 ± 8.1 in external rotation, and 58.5 ± 22.5 in abduction. The AHI increased 2.1 ± 0.8 mm and the VAS score significantly changed from 6.0 (5.0, 7.0) to 1.0 (0.0, 1.0), at the final follow-up. Eleven of the 89 patients experienced retears, and one patient needed reoperation. CONCLUSION In this study with at least 24-months of follow-up, SCR using the LHBT for massive rotator cuff tears could effectively relieve shoulder pain, restore shoulder function and increase shoulder mobility to some extent.

Abstract
Background Latissimus dorsi tendon transfer (LDTT) is increasingly performed with arthroscopic assistance, requiring an open axillary incision, which could increase risks of infection, hematoma, and lymphoedema. Technological advancements now enable LDTT to be fully arthroscopic, but its benefits and safety have not yet been confirmed. Purpose To compare the clinical outcomes and complication rates of arthroscopic-assisted versus full-arthroscopic LDTT for irreparable posterosuperior massive rotator cuff tears in shoulders with no surgical antecedents. Study Design Cohort study; Level of evidence, 3. Methods The study included 90 patients who had undergone LDTT over 4 consecutive years by the same surgeon and did not have prior surgery. During the first 2 study years, all procedures were arthroscopically assisted (n = 52), while during the last 2 years, all procedures were fully arthroscopic (n = 38). Procedure duration and all complications were recorded, as well as clinical scores and range of motion at minimum 24-month follow-up. To enable direct comparison between the techniques, propensity score matching was used to obtain 2 groups with equivalent age, sex, and follow-up. Results From the initial cohort of 52 patients who underwent arthroscopic-assisted LDTT, 8 had complications (15.4%), of which 3 (5.7%) required conversion to reverse shoulder arthroplasty and 2 (3.8%) required drainage or lavage. From the initial cohort of 38 patients who had full-arthroscopic LDTT, 5 had complications (13.2%), of which 2 (5.2%) required conversion to reverse shoulder arthroplasty but no patients (0%) required other procedures. Propensity score matching resulted in 2 groups, each comprising 31 patients, with similar outcomes in terms of clinical scores and range of motion. The procedure time was about 18 minutes shorter for full-arthroscopic LDTT, which had different complications (2 axillary nerve pareses) as compared with arthroscopic-assisted LDTT (1 hematoma and 2 infections). Conclusion Equivalent outcomes at minimum 24-month follow-up were found for arthroscopic-assisted and full-arthroscopic LDTT in terms of complications rates (15.4% and 13.2%, respectively), conversion to reverse shoulder arthroplasty (5.7% and 5.2%), clinical scores, and range of motion.

Assessment of the effectiveness of surgical treatment of patients with massive ruptures of rotator cuff tendons using latissimus dorsi tendon transposition. ACTA BIOMEDICA SCIENTIFICA 2022. [DOI: 10.29413/abs.2022-7.6.25] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/13/2023] Open
Abstract
Rotator cuff ruptures are the most common injuries of shoulder joint with an incidence of about 20 %. This pathology is more common in adults over 60 years of age because it is caused by degenerative changes in the tendon. Massive injuries account for 10–40 % of all rotator cuff injuries. Currently, there is no unified surgical tactics for the treatment of patients with massive ruptures of rotator cuff tendons.The aim. To assess the efficiency of transposition of the latissimus dorsi tendon in patients with massive ruptures of the rotator cuff tendon.Materials and methods. The study included 15 patients with Patte stage III massive ruptures of the rotator cuff who had transposition of the latissimus dorsi tendon.Results. The article presents clinical cases of surgical treatment of patients. The following criteria were assessed: mean age; time since injury; duration of the surgery; blood loss volume; functional results by the ASES (American Shoulder and Elbow Surgeons) Shoulder Score. Taking into account the ASES Shoulder Score indicators 1 year after the surgical treatment, the following results were obtained: excellent results – in 9 (53.3 %) cases; good results – in 1 (13.4 %) case; satisfactory results – in 5 (33.3 %) cases.Conclusion. When preserving the articular cartilage, the method of choice in the treatment of patients with massive ruptures of rotator cuff tendons is transposition of the latissimus dorsi tendon. At the same time, an incomplete restoration of the function of the injured limb was registered in 33.3 % of patients, which requires further study and modification of the known method of transposition of the latissimus dorsi tendon.

Biomechanical comparison of lower trapezius and latissimus dorsi transfer for irreparable posterosuperior rotator cuff tears using a dynamic shoulder model. J Shoulder Elbow Surg 2022; 31:2392-2401.

Abstract
BACKGROUND In the setting of irreparable posterosuperior rotator cuff tears (PSRCTs), lower trapezius transfer (LTT) may be anatomically better positioned for restoring the muscular force couple compared with latissimus dorsi transfer (LDT). The purpose of the study was to evaluate the effect of LTT and LDT on glenohumeral kinematics using a dynamic shoulder model. METHODS Ten fresh-frozen cadaveric shoulders (mean age: 56.5 ± 17.2 years) were tested using a dynamic shoulder simulator. The maximum abduction angle (MAA), superior humeral head migration (SHM), and cumulative deltoid forces (CDFs) were compared across 4 conditions: (1) native; (2) irreparable PSRCT; (3) LTT using an Achilles tendon allograft; and (4) LDT. MAA and SHM were measured using 3-dimensional motion tracking. CDF was recorded in real time throughout the dynamic abduction motion by load cells connected to actuators. RESULTS Compared to the native state, the PSRCT resulted in a significant decrease (Δ-24.1°; P < .001) in MAA, with a subsequent significant increase after LTT (Δ13.1°; P < .001) and LDT (Δ8.9°; P < .001). LTT achieved a significantly greater MAA than LDT (Δ4.2°; P = .004). Regarding SHM, both LTT (Δ-9.4 mm; P < .001) and LDT (Δ-5.0 mm; P = .008) demonstrated a significant decrease compared with the PSRCT state. LTT also achieved significantly less SHM compared with the LDT (Δ-4.4 mm; P = .011). Further, only the LTT resulted in a significant decrease in CDF compared with the PSRCT state (Δ-21.3 N; P = .048), whereas LTT and LDT showed similar CDF (Δ-11.3 N; P = .346). However, no technique was able to restore the MAA, SHM, and CDF of the native shoulder (P < .001, respectively). CONCLUSION LTT and LDT both achieved a significant increase in MAA along with significantly less SHM compared with the PSRCT state. Although LTT required significantly less compensatory deltoid forces compared with the PSRCT state, this was not observed for the LDT. Further, the LTT prevented loss of abduction motion and SHM more sufficiently. In the challenging treatment of irreparable PSRCTs, LTT may restore native glenohumeral kinematics more sufficiently, potentially leading to improved postoperative functional outcomes.

Abstract
Delayed treatment of shoulder instability results in bone loss requiring more-complicated surgery, in turn resulting in less-optimal outcomes. Similarly, delayed treatment of repairable rotator cuff tears results in irreparable tears requiring more-complicated surgery and resulting in less-optimal outcomes. Delayed treatment of shoulder pathology is a problem. Solutions include education and research investigation.

Abstract
The management of patients with massive posterosuperior rotator cuff tears without glenohumeral arthritis remains a challenge to arthroscopic surgeons. A wide variety of treatment options have been described, including latissimus dorsi tendon transfer (LDTT) and lower trapezius tendon transfer. These tendon transfers have been utilized to rebalance the glenohumeral force couple for patients with massive or irreparable posterosuperior rotator cuff tears. Proponents of the latissimus dorsi tendon transfer have touted several theoretical advantages, including improvement of the shoulder fulcrum, optimization of the deltoid function, improved humeral head depression, and restoration of shoulder motion. Currently accepted contra-indications to LDTT include glenohumeral arthritis, irreparable subscapularis tear, axillary nerve palsy and/or deltoid insufficiency. However, few studies have investigated the ideal patient selection for LDTT, particularly as it relates to clinically significant outcomes. Recent literature suggests a high rate of complications and re-tear following LDTT, and studies suggest that older age, previous surgery, true pseuoparalysis, lower low pre-operative acromiohumeral interval (AHI) or AHI reversibility negatively impact results. Ultimately, candidates for tendon transfer should be carefully stratified according to their modifiable and non-modifiable risk factors, and surgeons should understand how pre-operative patient characteristics may affect the treatment options available for this unique patient population. In the setting of supraspinatus and infraspinatus deficiency, we prefer to utilize the lower trapezius tendon transfer, given its more predictable handling characteristics, ease of harvest, and greater function consistency compared to LDTT.

[PMID: 34915140 DOI: 10.1016/j.arthro.2021.12.009] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Revised: 11/30/2021] [Accepted: 12/01/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE To determine the patient-acceptable symptom state (PASS) values for American Shoulder and Elbow Surgeons (ASES) score and the Constant-Murley (CM) score after arthroscopic-assisted latissimus dorsi tendon transfer (LDTT) and to identify potential factors affecting the achievement of PASS. METHODS Fifty consecutive patients who underwent arthroscopic-assisted LDTT between 2015 and 2020 were retrospectively analyzed. In total, 42 patients met the inclusion criteria with minimum follow-up of 1 year postoperative. Patients were evaluated preoperatively and 1-year postoperatively with multiple clinical measurements including ASES, CM, score and PASS. The primary outcome was identified as patient satisfaction which assessed with achievement of a PASS. Potential factors affecting the patient satisfaction including age, sex, body mass index, previous surgery, presence of pseudoparalysis, critical shoulder angle, shoulder abduction moment index, acromiohumeral interval (AHI) reversibility, Hamada grade and fatty infiltration were evaluated for their association with PASS value by stepwise logistic regression analysis. RESULTS A total of 42 patients were evaluated with mean follow-up 27.8 ± 8.21 months. The ASES and CM scores improved from preoperative means of 21.6 ± 6.5 and 25.2 ± 8.5 to 65.6 ± 20.7 points and 56.8 ± 16.5 points, respectively (P < .001). The PASS values for the ASES and CM scores were 62.4 and 52.5, respectively. The univariate analysis showed that older age (P = .021), presence of pseudoparalysis (P < .001), previous surgery (P = .016), lower preoperative AHI (P = .028), and lower AHI reversibility (P < .001) were all significantly associated with worse patient satisfaction. The multivariable logistic regression analysis showed that pseudoparalysis (P = .038) and AHI reversibility (P = .021) were independent prognostic factors affecting the achievement of a PASS after arthroscopic-assisted LDTT. The cutoff value for AHI reversibility to predict an achievement of PASS was found to be 4.0 mm. CONCLUSIONS Arthroscopic-assisted LDTT led to satisfactory results in patients with massive rotator cuff tears. However, pseudoparalysis and AHI reversibility were the most important independent prognostic factors that consistently reduced and increased, respectively, the odds of achieving a PASS. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
OBJECTIVES Reconstruction of the superior capsule for treatment of irreparable supraspinatus tendon tears. INDICATIONS Irreparable supraspinatus tendon tear; centered humeral head; largely intact cartilage; largely intact transversal "force-couple". CONTRAINDICATIONS Decentered humeral head; osteoarthritis of the glenohumeral joint/cuff tear arthropathy; irreparable anterosuperior and posterosuperior cuff tears. SURGICAL TECHNIQUE Arthroscopic superior capsule reconstruction (SCR) is performed in beach-chair position. At first the bone bed of the glenoid and the insertion of the supraspinatus tendon are prepared using a bone burr. Now, depending on the integrity of the long biceps tendon, two options are possible. Option 1: In the case of an existing long biceps tendon, a biceps tendon tenodesis to the greater tubercle is performed. Therefore, the long head of the biceps is fixed central to the former insertion of the supraspinatus tendon, using a suture anchor. Option 2: In the case of a nonexisting or degeneratively modified long biceps tendon, a PushLock® anchor (Arthrex, Inc. Naples, FL, USA) loaded with a FiberTape® (Arthrex, Inc. Naples, FL, USA) is placed centrally onto the glenoid. Now, the actual superior capsule reconstruction is completed. Two suture anchors are placed at the glenoid and two SwiveLock® anchors, each loaded with a FiberTape®, (Arthrex, Inc. Naples, FL, USA) are placed at the footprint of the supraspinatus tendon at the greater tubercle. The tapes are shuttled extra-articularly and the graft size is evaluated by measuring the distance between the anchors. The graft is customized to that size and armed with the tapes. Using the tapes of the glenoidal anchors, as tension ropes, the graft is placed intra-articularly. Medially the sutures are tied and laterally the graft is fixed in a knotless lateral row manner. The tails of the tape, of the glenoidal PushLock® (Arthrex, Inc. Naples, FL, USA) anchor are fixed within the lateral row and are tensioned above the graft. Afterwards side-to-side sutures to the infraspinatus and a subacromial decompression are completed. POSTOPERATIVE MANAGEMENT The arm is placed in a sling for 6 weeks, afterwards active physiotherapy begins. Passive-assisted physiotherapy is started on postoperative day 1. RESULTS Between 2017 and 2019, 11 patients were treated with SCR. As the combined procedure is our new treatment algorithm, case studies will be presented. For this study, 9 patients treated with singular SCR, with a mean follow-up of 18 months, were recruited. A statistically significant reduction of pain (VAS 6.3 → VAS 2), a good postoperative forward flexion (mean 138°; 56 standard deviation [SD]), and external rotation (mean 37°; 21 SD) were measured. A mean ASES of 76.5 (18 SD) a mean DASH of 17.8 (14 SD) and a mean Constant score of 64.6 (25 SD) were achieved.

Biomechanical analysis of arthroscopically assisted latissimus dorsi transfer fixation for irreparable posterosuperior rotator cuff tears-Knotless versus knotted anchors.

Abstract
We compared the construct stability of traditional knotted techniques with modern knotless anchor systems used in arthroscopically assisted latissimus dorsi transfers (aLDTs) for irreparable posterosuperior rotator cuff tears. Eighteen cadaveric shoulders were age- and gender-matched to the following three groups: knotted group (two knotted anchors); knotless group (two knotless anchors); and triple anchor group (two knotless anchors; one all-suture anchor at the apex of the humeral head). All tendons were cyclically loaded in line of the aLDT over 400 cycles followed by a load to failure test. Outcome measures were the ultimate load to failure, elongation, construct stiffness, and failure modes. The triple anchor group revealed the highest ultimate load to failure (431 ± 78 N) compared with the knotted (326 ± 52 N; p = .022) and knotless (353 ± 105 N; p = .129) groups. Total elongation and construct stiffness were not significantly different comparing all three groups. The failure modes were: anchor pull-out in all specimen of the knotted group; three (50%) anchor pull-out and three suture pull-out in the knotless group (p = .046); four (67%) anchor pull-out, one (17%) suture pull-out and one tendon pull-out in the triple anchor group. Biomechanical analyses of knotless fixation techniques for aLDTs show similar construct stability and elongation compared with the traditional, knotted techniques. Bone fixation seems to be improved with the knotless anchor systems. In our practice, we continue to use the knotless fixation technique for aLDT and in the situation of weak, osteoporotic bone, we add a third (all-suture) anchor to improve construct stability.

Abstract
OBJECTIVE We analyzed the clinical and functional results of patients with irreparable posterosuperior rotator cuff tears treated with arthroscopic-assisted latissimus dorsi transfer and the clinical relevance of the addition of partial repair of the remaining cuff to the transfer. METHODS This was a prospective cohort study that included patients diagnosed with irreparable massive rotator cuff tears treated by arthroscopic-assisted latissimus dorsi transfer between 2015 and 2018. Demographic characteristics, clinical and functional outcomes (Constant-Murley (CS) score and subjective shoulder value (SSV)), and the incidence of complications were evaluated. Clinical outcomes were compared between patients treated with transfer alone and transfer with partial cuff repair. RESULTS Fifteen patients were included, with an average follow-up of 37 ± 16 months. The median duration of symptoms before surgery was 66 weeks (24-208). A significant increase in forward elevation of 52° (p < 0.003) and abduction of 48° (p < 0.001) was obtained. The CS score increased by 48 points (p < 0.001), and the SSV changed from 29% preoperatively to 70% postoperatively (p < 0.001), with a significant decrease in the visual analog pain score from 7 to 1 (p < 0.001). In 10 patients, partial repair of the rotator cuff was also performed. No statistically significant differences were found in these patients compared with patients treated with transfer alone. Two patients presented complications, including transient sensitive neuropraxia of the axillary nerve and seroma, which were managed conservatively and did not affect the outcomes. CONCLUSION Arthroscopic-assisted latissimus dorsi transfer is a safe technique that significantly improves clinical and functional outcomes in selected patients. Longer follow-up and comparison with other treatment options are needed to confirm these excellent results in this group of difficult-to-treat patients. LEVEL OF EVIDENCE IV Nil.

Abstract
Background Understanding muscle and tendon anatomy is of tremendous importance to achieve optimal surgical execution and results in tendon transfers around the shoulder. The aim of this study was to introduce and describe an additional distal muscle slip of the teres major (TM). Methods Sixteen fresh-frozen cadaver shoulders were dissected with the deltopectoral approach. The ventral latissimus dorsi (LD) tendon was harvested, and the shoulders were analyzed for the presence/absence of a distal teres major slip (dTMs) and its dimensions and relationship with the TM and LD tendons. Results The dTMs was identified in 12 shoulders (75%). It was always distal to the TM tendon and visible during the deltopectoral approach. There was a clear separation between the TM proximally and dTMs tendon distally. At the humeral insertion, both tendons had a common epimyseal sheet around the teres major and inserted continuously at the humerus. The mean width of the dTMs tendon at the insertion was 13 ± 4 mm (range, 7–22 mm). The total lengths of the dTMs tendon and LD tendon were 40 ± 7 mm (range, 25–57 mm) and 69 ± 7 mm (range, 57–79 mm), respectively (p < 0.001). The dTMs muscle showed direct adhesions in ten shoulders (83%) with the LD muscle. Conclusions This is the first macroscopic description of an additional distal slip of the teres major muscle. The dTMs has a separate (distal) but continuous (mediolateral) insertion at the humerus within a common epimyseal sheet around the TM. The dTMs tendon is visible during the deltopectoral approach and can therefore provide a lead structure, particularly in ventral LD transfers with the deltopectoral approach.
