Arthroscopic Debridement for Irreparable Rotator Cuff Tears

[Research progress of arthroscopic long head of biceps tendon transposition in treatment of irreparable massive rotator cuff tears]

OBJECTIVE

To review the research progress of arthroscopic long head of biceps tendon (LHBT) transposition in treatment of irreparable massive rotator cuff tears.

METHODS

The domestic and foreign related literature in recent years on the treatment of irreparable massive rotator cuff tears with different LHBT transposition methods under arthroscopy was reviewed and analyzed.

RESULTS

Arthroscopic LHBT transposition is an effective method for irreparable massive rotator cuff tears, which mainly includes "proximal cut", "both two cuts", "distal cut", and "no cut". Different methods of LHBT transposition can achieve good effectiveness, but its long-term effectiveness needs further follow-up.

CONCLUSION

Arthroscopic LHBT transposition in treatment of irreparable massive rotator cuff tears is simple and effective. The patients can recover quickly after operation with less injury. But the technique has higher requirements for surgeons, and the indications must be strictly controlled.

Functional outcome of arthroscopic debridement for massive, irreparable rotator cuff tears

Rotator cuff tears are a common cause of shoulder pain in the middle-aged population. The treatment of these lesions must be individualized on the basis of the type of patient, the clinical and anatomical picture. Arthroscopic debridement is indicated in painful massive tears, in the absence of severe functional impairment of the shoulder. The aim of this study is the evaluation of the medium term clinical results of this procedure.  We retrospectively assessed patients who underwent arthroscopic debridement surgery for massive rotator cuff injury in the period between January 2011 and December 2016 at our institution. A group of patients underwent a follow-up evaluation during which the Constant Score, Oxford Shoulder Score and NRS pain score were compiled. Those who were unable to attend the evaluation were assessed through a telephone questionnaire aimed at investigating pain and degree of satisfaction with the  treatment.  93% of patients were satisfied with the results obtained, with an average NRS of 1.31 for patients undergoing the medical examination and 0.68 for patients contacted by telephone. The mean Constant score of the evaluated patients was 75.6 ± sd, with a mean strength of 3.92 ± sd, while the mean value of the Oxford Shoulder Score was 16.8 ± sd.  The study suggests that arthroscopic debridement is a viable option for the surgical treatment of massive rotator cuff tears. The clinical results and patient satisfaction are conditioned by the preoperative functional status: an optimal outcome can be expected for painful shoulders with sufficiently preserved active mobility.

Arthroscopic Superior Capsular Reconstruction With Biceps Autograft: Snake Technique

Many options have been developed to treat irreparable massive cuff tears. Superior capsular reconstruction has been reported as one of the treatment options for relatively young patients with irreparable massive cuff tear. However, this original technique has a disadvantage of requiring a tensor facia lata autograft. It requires another incision at the lateral thigh and can be a cause of thigh pain. This article describes our modified technique for arthroscopic superior capsule reconstruction using the biceps autograft to preserve the long head of the biceps tendon anchors to the glenoid labrum (the snake technique).

Failed Dermal Allograft Procedures for Irreparable Rotator Cuff Tears Can Still Improve Pain and Function: The "Biologic Tuberoplasty Effect"

Background:

Acellular dermal matrices (ADMs) have been used in the treatment of shoulders with massive rotator cuff tears (MRCTs). Despite clinical improvement, correlation of clinical findings with ADM integrity on imaging has not been investigated.

Hypothesis:

The pain in shoulders with MRCTs is partially due to bone-to-bone contact between the tuberosity and acromion. Coverage of the tuberosity with an intact graft or a graft that is torn in a way that the tuberosity remains covered will act as an interpositional tissue, preventing bone-to-bone contact and leading to clinical improvement.

Study Design:

Case series; Level of evidence, 4.

Methods:

Between 2006 and 2016, a total of 25 shoulders with MRCTs underwent a procedure with an ADM. Pre- and postoperative visual analog scale (VAS) results, American Shoulder and Elbow Surgeons (ASES) score, Hamada grade, and Goutallier classification were reviewed. A postoperative magnetic resonance imaging (MRI) was obtained in 22 (88%) shoulders. The status of the graft was divided into the following categories: type I, intact graft; type II, graft tear with tuberosity covered; and type III, graft tear with tuberosity uncovered (bare).

Results:

The mean patient age was 61 years (range, 49-73 years), and the mean follow-up was 25.6 months (range, 10-80 months). Mean length from surgery to postoperative MRI was 13.9 months (range, 6-80 months). The graft was torn in 59% (13/22 shoulders). Significant improvements were found in VAS and ASES scores (7 vs 0.7 and 32.6 vs 91.2, respectively; P < .01) for type I grafts and in VAS and ASES scores (8.1 vs 1.3 and 26.3 vs 84.6, respectively; P < .01) for type II grafts. No difference was found in postoperative VAS and ASES (0.7 vs 1.3 and 91.2 vs 84.6, respectively; P = .8) between type I and type II grafts. No improvement was seen in VAS (7.3 vs 5.7; P = .2) or ASES (30.6 vs 37.2; P = .5) for type III grafts.

Conclusion:

MRI appearance of the graft has a significant impact on functional outcomes. Patients with an intact graft or a graft tear leaving the tuberosity covered have lower pain and higher functional scores than those in whom the torn graft leaves the tuberosity uncovered.

Nonarthroplasty Surgical Treatment Options for Massive, Irreparable Rotator Cuff Tears

Massive, irreparable rotator cuff tears (MIRCTs) provide a significant dilemma for orthopaedic surgeons. One treatment option for MIRCTs is reverse total shoulder arthroplasty. However, other methods of treating these massive tears have been developed. A search of the current literature on nonoperative management, arthroscopic debridement, partial repair, superior capsular reconstruction (SCR), graft interposition, balloon spacer arthroplasty, trapezius transfer, and latissimus dorsi transfer for MIRCTs was performed. Studies that described each surgical technique and reported on clinical outcomes were included in this review. Arthroscopic debridement may provide pain relief by removing damaged rotator cuff tissue, but no functional repair is performed. Partial repair has been suggested as a technique to restore shoulder functionality by repairing as much of the rotator cuff tendon as possible. This technique has demonstrated improved clinical outcomes but also fails at a significantly high rate. SCR has recently gained interest as a method to prohibit superior humeral head translation and has been met with encouraging early clinical outcomes. Graft interposition bridges the gap between the retracted tendon and humerus. Balloon spacer arthroplasty has also been recently proposed and acts to prohibit humeral head migration by placing a biodegradable saline-filled spacer between the humeral head and acromion; it has been shown to provide good clinical outcomes. Both trapezius and latissimus dorsi transfer techniques involve transferring the tendon of these respective muscles to the greater tuberosity of the humerus; these 2 techniques have shown promising restoration in shoulder function, especially in a younger, active population. Arthroscopic debridement, partial repair, SCR, graft interposition, balloon spacer arthroplasty, trapezius transfer, and latissimus dorsi transfer have all been shown to improve clinical outcomes for patients presenting with MIRCTs. Randomized controlled trials are necessary for confirming the efficacy of these procedures and to determine when each is indicated based on specific patient and anatomic factors.

Arthroscopic In Situ Superior Capsular Reconstruction Using the Long Head of the Biceps Tendon

Large to massive rotator cuff tears are challenging to repair, although there are several options for dealing with them. Among them, superior capsular reconstruction was recently introduced as an effective procedure for retaining the static stability of the shoulder joint and preventing the progression to cuff tear arthropathy. The purpose of this technique-based article is to describe a surgical option, called arthroscopic in situ superior capsular reconstruction, for large to massive rotator cuff tears using the long head of the biceps tendon.
