Superior capsular reconstruction has received increased attention as a surgical technique to address massive 'irreparable' rotator cuff tears; however, the functional limitations and surgical techniques associated with this repair have yet to be sufficiently explored. The goal of this study was to utilize a multidisciplinary approach to characterize the biomechanics of this repair by: 1) identifying activities of daily living that may overburden graft, and 2) optimizing surgical techniques used during implantation...

PURPOSE: The factors affecting the anatomical and functional outcomes of arthroscopic superior capsular reconstruction (ASCR) were investigated in this study. Continuity between the posterior remnant tissue and graft, as well as medial-to-lateral anatomical graft continuity, might play a vital role in shoulder stability and functional recovery, which could be correlated with postoperative factors such as the acromiohumeral distance (AHD). METHODS: Thirty-two patients (36 shoulders) who underwent ASCR were included...

Superior capsular reconstruction (SCR) demonstrated its efficacy as a treatment option available in patients affected with irreparable posterosuperior rotator cuff tears without any signs of arthritis. Originally, the fascia lata autograft was fixed medially to the glenoid (with two or more anchors) and laterally to the greater tuberosity (with a compression double-row technique using four anchors or three transosseous tunnels). Additionally, side-to-side sutures were used to anteriorly and posteriorly connect the graft to the native residual rotator cuff tissue...

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...

PURPOSE: This outcome analysis presents 88 consecutive shoulders presenting with irreparable rotator cuff tears that we treated with arthroscopic superior capsular reconstruction (SCR) using an acellular dermal allograft. We also present the concept of superior capsular distance to quantitatively measure the decreased distance present upon restoration of superior capsular integrity. METHODS: A retrospective review was conducted of patients treated with arthroscopic SCR with a minimum 12-month follow-up...

PURPOSE: To prospectively evaluate the sensitivity and specificity of magnetic resonance imaging (MRI) for diagnosing ramp lesions, to compare them between 1.5- and 3-T MRI, and to evaluate whether bone contusion of the posterior lip of the medial tibial plateau was associated with ramp lesions. METHODS: For 155 knees that underwent primary ACL reconstruction, we prospectively examined for ramp lesions and medial meniscal body tears on MRI. MRI diagnosis of ramp lesions required high signal irregularity of the capsular margin or separation in the meniscocapsular junction of the medial meniscus posterior horn on sagittal images...

Massive rotator cuff tears are particularly challenging to treat and severely limit the function of the shoulder. Compared with a small rotator cuff tear, massive tears are more unpredictable and usually present with low tendon quality. When performing an anatomical repair of the rotator cuff, the surgical treatment is often associated with failure of the construct. An alternative procedure that can be performed in the setting of a massive tear is superior capsular reconstruction (SCR), using an autograft or allograft...

An irreparable cuff tear is defined as the inability to achieve direct repair of native tendon to the great tuberosity despite intra- and extra-articular release of the remaining tissue. Three distinct anatomic patterns are identified: posterosuperior cuff tears which involve the supraspinatus, infraspinatus and teres minor; anterosuperior tears which involve the supraspinatus and subscapularis; and global tears which comprise both. Subacromial debridement and tenotomy or tenodesis of the long head of the biceps are proposed for older patients with a functional but very painful shoulder...

PURPOSE OF REVIEW: The purposes of this review were to provide an overview of the current practice of evaluating the postoperative rotator cuff on imaging and to review the salient imaging findings of the normal and abnormal postoperative rotator cuff, as well as of postoperative complications. RECENT FINDINGS: The repaired rotator cuff frequently appears abnormal on magnetic resonance imaging (MRI) and ultrasound (US). Recent studies have shown that while the tendons typically normalize, they can demonstrate clinically insignificant abnormal imaging appearances for longer than 6 months...

Massive irreparable rotator cuff tears remain a challenging condition during daily clinical practice. Irreversible fatty infiltration of muscles and excessive chronic retraction of tendons predispose to high failure rates of their surgical treatment. Superior capsular reconstruction with either fascia lata autograft or a dermal allograft patch is a newly described solution that could prevent superior humeral head migration and restore the anteroposterior shoulder muscle force couples. The purpose of this article is to propose a technical modification of superior capsular reconstruction using long head of the biceps tendon autograft...

A subscapularis complete tear presents its own challenges in management. The glenohumeral biomechanics and force couple are reliant on a competent and functioning subscapularis muscle. An irreparable subscapularis makes those same challenges even more difficult to address. Traditionally, this problem has been addressed with tendon transfers, including pectoralis major or latissimus dorsi. These techniques can alter the ideal biomechanics of the shoulder and have high rates or failure. Iliotibial autograft or tibialis anterior have also been wrought with high failure rates...

CASE: Chronic massive irreparable rotator cuff tears remain challenging to treat. We present the case of a 70-year-old active and healthy woman who presented with 6 months of worsening shoulder pain and function; she had experienced considerable deterioration over the past 2 months. Nonoperative management of the massive rotator cuff tear was not successful. Superior capsule reconstruction (SCR) was performed with a partial rotator cuff repair. CONCLUSION: SCR is an exciting advancement for the chronic massive irreparable rotator cuff tear, one of the more challenging problems encountered by shoulder surgeons...

BACKGROUND: Superior capsular reconstruction (SCR) was recently introduced as a treatment for irreparable superior rotator cuff tears in younger patients. Purpose/Hypothesis: The purpose was to assess the biomechanical strength of 3 methods for fixation of the graft to the glenoid for SCR. It was hypothesized that a 4-anchor technique would provide greater load to failure than 3-anchor techniques. STUDY DESIGN: Controlled laboratory study. METHODS: Thirty-six cadaveric specimens were randomized into 3 groups of previously established glenoid-side graft fixation techniques: (1) three 3...

Hip fractures pose a major health problem throughout the world due to their devastating impact. Current theories for why these injuries are so prevalent in the elderly point to an increased propensity to fall and decreases in bone mass with ageing. However, the fracture mechanisms, particularly the stress and strain conditions leading to bone failure at the hip remain unclear. Here, we directly examined the cortical bone from clinical intra-capsular hip fractures at a microscopic level, and found strong evidence of compression induced failure in the superior cortex...

Background: Medial instability of the patellofemoral joint is a rare but known phenomenon that may result from an incompetent lateral patellofemoral ligament (LPFL). Surgical reconstruction of the LPFL has been described. However, anatomic details of the ligament have not been the subject of scrutiny. Purpose: To describe the anatomic origin and insertion of the LPFL. Study Design: Descriptive laboratory study. Methods: Ten fresh-frozen, unpaired human cadaveric knees (mean age, 57 years) were dissected to identify the LPFL...

Non-arthroplasty treatment options for pseudoparalysis of the shoulder are preferable in the younger patient population. Although there are differing philosophies among shoulder surgeons, many prefer to avoid reversed total shoulder arthroplasty for patients under age 60 years. Arthroscopically assisted latissimus dorsi transfer may be a good alternative for these patients, but how the results compare with arthroscopic superior capsular reconstruction is the question.

Superior capsular reconstruction (SCR) of the shoulder has recently gained popularity as an option for joint-preserving shoulder surgery for patients with an irreparable rotator cuff tear. In the absence of glenohumeral arthritis, rotator cuff tear irreparability should only be diagnosed for most patients after a careful diagnostic arthroscopy. Superior capsular reconstruction adds biological, passive, superior constraint to the glenohumeral joint, thereby optimizing the rotator cuff force couples and improving joint kinematics...

This study evaluates a novel limited submuscular direct-to-implant technique utilizing AlloMax where only the upper few centimeters of the implant is covered by the pectoralis, whereas the majority of the implant including the middle and lower poles are covered by acellular dermal matrix. METHODS: The pectoralis muscle is released off its inferior and inferior-medial origins and allowed to retract superiorly. Two sheets of AlloMax (6 × 16 cm) are sutured together and secured to the inframammary fold, serratus fascia, and the superiorly retracted pectoralis...

Superior capsular reconstruction (SCR) is a novel technique for treating irreparable rotator cuff tears in younger patients in whom a reverse total shoulder arthroplasty is not the optimal treatment choice. This case study describes a middle-aged male with a recurrent, massive, irreparable rotator cuff tear treated with SCR that subsequently failed at the glenoid attachment. The patient underwent successful arthroscopic revision of the SCR. The case illustrates the MRI and arthroscopic correlations of the failed dermal allograft reconstruction, which to our knowledge has not been previously shown in the radiology literature...

Massive irreparable rotator cuff tears are difficult to treat. Although several treatment options exist, none provides superior long-term results. There is no consensus on optimal surgical technique. Superior capsular reconstruction is an operative treatment option aimed at restoring native biomechanics of the glenohumeral joint by providing a restraint to superior subluxation. Partial rotator cuff repair for massive tears has also been shown to improve shoulder kinematics and can be performed in conjunction with superior capsule reconstruction...
