Our objective was to determine the plasma levels of substance P (SP) in patients with postoperative stiffness after arthroscopic rotator cuff repair.

Plasma samples were obtained at 15 months from surgery from 2 groups of patients who underwent arthroscopic repair of a rotator cuff tear. In Group 1, 30 subjects (14 men and 16 women, mean age: 64.6 years, range 47 to 78) with shoulder stiffness 15 months after arthroscopic rotator cuff repair were recruited. In Group 2, 30 patients (11 men and 19 women, mean age: 57.8 years, range 45 to 77) were evaluated 15 months after successful arthroscopic rotator cuff repair. Immunoassays were performed with commercially available assay kits to detect the plasma levels of SP.

The mean plasma levels of SP in patients with postoperative stiffness were significantly greater than those in the control group (81.06 ± 27.76 versus 23.49 ± 5.64, P < 0.05).

The plasma concentrations of substance P in patients with shoulder stiffness after arthroscopic rotator cuff repair are higher compared to plasma levels of SP in patients with a good postoperative outcome. The neuronal upregulation of SP shown in the plasma of patients with post operative shoulder stiffness may underlay not only the symptoms of adhesive capsulitis, but also its development.

Arthroscopic management has been recommended for some SLAP lesions, but no studies have focused on patients over 50 with rotator cuff tear and Type II SLAP lesion. Our hypothesis was that there was no difference in clinical outcome between repairing of the Type II SLAP lesion and tenotomy of the long head of the biceps tendon after having repaired the rotator cuff tear. This was a randomized controlled clinical trial.

We recruited 63 patients. In 31 patients, we repaired the rotator cuff and the Type II SLAP lesion (Group 1). In the other 32 patients, we repaired the rotator cuff and tenomized the long head of the biceps (Group 2). 7 patients (2 in the group 1 and 5 in the group 2) were lost to final follow up.

At the 5.2 year follow-up, statistically significant differences were seen with respect to the UCLA score and ROM values. In Group 1 (SLAP repair and rotator cuff repair), the UCLA showed a statistically significant improvement from a pre-operative average rating of 10.4 (range 6 to 14) to an average of 27.9 (24–35) postoperatively (P< 0.001). In Group 2 (biceps tenotomy and rotator cuff repair) the UCLA showed a statistically significant improvement from a pre-operative average rating of 10.1 (range 5 to 14) to an average of 32.1 (range 30 to 35) post-operatively (P< 0.001) There was statistically significant difference in total post-operative UCLA scores and ROM when comparing the two groups post-operatively (P< 0.05).

There are no advantages in repairing a Type II SLAP lesion when associated with a rotator cuff tear in patients over 50. Rotator cuff repair alone is sufficient to produce a good post-operative outcome, allowing to avoid post-operative stiffness of the shoulder.

Postoperative stiffness (POS) of the shoulder may occur after an apparently successful reconstruction of a rotator cuff tear.

The role of the peripheral nervous system in tissue healing has only recently been recognized.

We determined the plasma levels of SP in patients with postoperative stiffness after arthroscopic repair of a rotator cuff tear, and compared them with those in patients with a good outcome after arthroscopic rotator cuff repair.

Plasma samples were obtained at 15 months from surgery from 2 groups of patients who underwent arthroscopic repair of a rotator cuff tear. In Group 1, 30 subjects (14 men and 16 women, mean age: 64.6 years, range 47 to 78) with shoulder stiffness 15 months after arthroscopic rotator cuff repair were recruited. In Group 2, 30 patients (11 men and 19 women, mean age: 57.8 years, range 45 to 77) were evaluated 15 months after successful arthroscopic rotator cuff repair. Immunoassays were performed with commercially available assay kits to detect the plasma levels of SP.

Statistical analysis were performed with Wilcoxon Sign Rank test. Significance was set at P< 0.05

The concentrations of the neuropeptide SP in sera were measurable in all patients. Patients with postoperative stiffness had statistically significant greater plasma levels of SP than patients in whom arthroscopic repair of rotator cuff tears had resulted in a good outcome (P < 0.05)

Postoperative stiffness (POS) of the shoulder may occur after an apparently successful reconstruction of a rotator cuff tear.

An increased amount of SP in the subacromial bursa has been correlated with the pain caused by rotator cuff disease.

SP stimulates DNA synthesis in fibroblasts, which are the cellular components of the adhesive capsulitis of the shoulder. Also, SP is a pain transmitter peptide, and pain may cause a secondary muscular and/or capsular contracture.

Our results show that the plasma concentrations of substance P in patients with shoulder stiffness after arthroscopic rotator cuff repair are higher compared to plasma levels of SP in patients with a good postoperative outcome.

We cannot determine the cause of POS in our patients, but the findings of this study suggest a possible neuronal role in the pathophysiology of POS after arthroscopic repair of rotator cuff tears. The knowledge of the pathophysiological role of sensory nerve peptides in tissue repair in these patients could open new therapeutic options to manage conditions of the musculo-skeletal system with impaired tissue-nervous system interaction.

Restoring of anatomic footprint may improve the healing and mechanical strength of repaired tendons. A double row of suture anchors increases the tendon-bone contact area, reconstituting a more anatomic configuration of the rotator cuff footprint.

We aimed to investigate if there were differences in clinical and imaging outcome between single row and double row suture anchor technique repairs of rotator cuff tears.

We recruited 60 patients affected by a rotator cuff tear diagnosed on clinical grounds, magnetic resonance imaging evidence of cuff tear and inadequate response to nonoperative management, an unretracted and sufficiently mobile full-thickness rotator cuff lesion to allow a double row repair found at the time of surgery.

In 30 patients, rotator cuff repair was performed with single row suture anchor technique (Group 1). In the other 30 patients, rotator cuff repair was performed with double row suture anchor technique (Group 2). 8 patients (4 in the single row anchor repair group and 4 in the double row anchor repair group) were lost at follow up.

A modified UCLA shoulder rating scale was used to evaluate preoperative and postoperative shoulder pain, function and range of motion, strength and patient satisfaction. All patients received a post-operative MR arthrography at the final follow up appointment.

At the 2 year follow-up, no statistically significant differences were seen with respect to the UCLA score and ROM values. Post-operative MR arthrography at 2 years of follow up in group 1 showed intact tendons in 14 patients, partial thickness defects in 10 patients and full thickness defects in 2 patients. In group 2, MR arthrography showed an intact rotator cuff in 18 patients, partial thickness defects in 7 patients, and full thickness defects in 1 patient.

Biomechanical studies comparing single versus double row suture anchor technique for rotator cuff repair show that a double row of suture anchors increases the tendonbone contact area and restores the anatomic rotator cuff footprint, providing a better environment for tendon healing.

Our study shows that there are no advantages in using a double row suture anchor technique to restore the anatomical footprint. The mechanical advantages evidenced in cadaveric studies do not translate into superior clinical performance when compared with the more traditionally, technically less demanding, and economically more advantageous technique of single row suture anchor repair.

Several studies showed the efficacy of arthroscopic repair for Type II SLAP lesions without other associated lesions, but the only data reported on the association of arthroscopic repair of Type II SLAP lesion and rotator cuff tears involve young and active patient. To our knowledge, no studies have focused on patients over 50.

We evaluated the results of a randomized controlled trial of arthroscopic repair in patients over 50 with rotator cuff tears and Type II SLAP lesion in whom the repair was effected repairing the two lesions, or repairing the rotator cuff tears and performing a tenotomy of the long head of the biceps.

We recruited 63 patients. In 31 patients, we repaired the rotator cuff and the Type II SLAP lesion (Group 1). In the other 32 patients, we repaired the rotator cuff and tenotomized the long head of the biceps (Group 2). 7 patients (2 in the group 1 and 5 in the group 2) were lost to final follow up.

A modified UCLA shoulder rating scale was used to evaluate pre-operative and post-operative shoulder pain, function, active forward flexion, strength and patient satisfaction.

Of 63 patients randomized to one of the two treatments, 5.2 year results were available for 56. 7 patients (2 in the group 1 and 5 in the group 2) did not return at the final follow up.

Statistically significant differences were seen with respect to the UCLA score and ROM values at final follow-up In Group 1 (SLAP repair and rotator cuff repair), the UCLA showed a statistically significant improvement from a pre-operative average rating of 10.4 (range 6 to 14) to an average of 27.9 (24–35) postoperatively (P< 0.001). In Group 2 (biceps tenotomy and rotator cuff repair), the UCLA showed a statistically significant improvement from a pre-operative average rating of 10.1 (range 5 to 14) to an average of 32.1 (range 30 to 35) post-operatively (P< 0.001) There was statistically significant difference in total post-operative UCLA scores and ROM when comparing the two groups post-operatively (P< 0.05).

Arthroscopic management has been recommended for some SLAP lesions, but no studies have focused on patients over 50 with rotator cuff tear and Type II SLAP lesion.

We compared the clinical outcome of patients over 50 affected with rotator cuff tears and Type II SLAP lesion in whom both the defects were repaired, or the rotator cuff tear was repaired and the long head of the biceps tendon was tenotomized. In our hands, the association of rotator cuff repair and biceps tenotomy provides better clinical outcome compared with repair of Type II SLAP lesion and of the rotator cuff.

The repair of the two defects, in fact, can lead to worst clinical results compared with association Rotator cuff repair alone is sufficient to determine a good post-operative outcome, allowing to avoid post-operative stiffness of the shoulder.

Aims: The aim of this study was to analyze the morphological features of the human surgical specimens of normal supraspinatus tendon from patients with rotator cuff tears and glenohumeral instability.

Methods: 41 subjects were recruited for the study. 20 subjects (group 1) sustained a rotator cuff tear and proceeded arthroscopic repair of the lesion. 21 subjects (group 2) underwent surgery due to glenohumeral instability. During surgery, under arthroscopic control, a full thickness supraspinatus tendon biopsy was harvested in the middle portion of the tendon. All slices were processed for histological analysis

Results: On surgical specimens of supraspinatus tendon from patients with rotator cuff tears, but not from patients with instability, we found increased preponderance of hyaline degeneration, fibrocartilaginous or chondroid metaplasia, calcification, lipoid degeneration, mucoid or myxoid.

Degenerative changes were more evident on the articular side of the rotator cuff.

Conclusions: The present study provides a description of the histological architecture of human surgical specimens of normal supraspinatus tendon from patients with rotator cuff tears. Preexisting degenerative change in the supraspinatus tendon seems to be the main cause of rotator cuff tears.

Aims: We reviewed our experience to determine the results of arthroscopic repair in patients over 50 with rotator cuff tears and Type II SLAP lesion in whom the repair was effected repairing the two lesions, or repairing the rotator cuff tears and performing a tenotomy of the long head of the biceps.

Methods: We recruited 121 patients older than 50 years in whom a symptomatic rotator cuff tear had failed non-surgical management and was affecting daily activities.

We assigned them retrospectively to one of the two groups: Group 1 underwent arthroscopic repair of the rotator cuff and repair of the type II SLAP lesion. Group 2 underwent arthoscopic repair of the rotator cuff tear and a tenotomy of the long head of the biceps.

Results: There was statistically significant difference in total postoperative UCLA scores and ROM when comparing the two groups postoperatively (P< 0.05).

Conclusions: We compared the clinical outcome of patients over 50 affected by the association of rotator cuff tears and Type II SLAP lesion, in whom both the defects were repaired, or the rotator cuff tear was repaired and the long head of the biceps tendon was tenotomized. In our hands, the association of rotator cuff repair and biceps tenotomy provides better clinical outcome compared with the association of Type II SLAP lesion repair and rotator cuff repair at three years of follow-up.

Among the variety of differential diagnoses for chronic patellar tendinopathy, isolated tuberculosis is extremely rare. We report such a case, without any evident primary contiguous or distant focus, in a 31-year-old immunocompetent male.
