Arthroscopic Transtendon Repair of Partial-Thickness Articular-Side Rotator Cuff Tears

Comparison of the clinical efficacy and prognosis of the two techniques for treating partial articular-sided supraspinatus tendon tears under arthroscopy

BACKGROUND

At present, shoulder arthroscopy is usually used for treatment of rotator cuff injuries. There is still debate over the precise technique of using shoulder arthroscopy to treat partial articular-sided supraspinatus tendon injuries.

OBJECTIVE

To compare the clinical efficacy of the arthroscopic transtendon repair method and the arthroscopic full-thickness repair method in the treatment of patients with Ellman III partial articular-sided supraspinatus tendon tears and to analyze the influencing factors of postoperative efficacy.

STUDY DESIGN

Cohort study; level of evidence,4.

METHODS

A total of 84 partial-thickness rotator cuff tear (PTRCT) patients with Ellman III injuries who underwent surgical treatment in our hospital between January 2017 and January 2020 were selected and divided into the arthroscopic trans-tenon repair group (32 cases) and the arthroscopic full-thickness repair group (52 cases). Shoulder joint pain and functional status were assessed by the Constant score, ASES score and VAS score; shoulder mobility was assessed by measuring shoulder ROM. The clinical outcomes of the two groups of patients were compared, and the factors affecting the postoperative efficacy of the patients were investigated.

RESULTS

All patients were followed up for at least 2 years. The Constant score, ASES score, and VAS score of the two groups of patients were all improved compared with those before surgery, and the differences were statistically significant (P < 0.05). There were no significant differences in the Constant score, ASES score, or VAS score between the two groups (P > 0.05). The results of binary logistic regression analysis showed that the preoperative ASES score and whether biceps tenotomy was performed were independent risk factors for satisfactory postoperative efficacy (P < 0.05).

CONCLUSION

For patients with Ellman III partial articular-sided supraspinatus tendon tears, the arthroscopic transtendon repair method and the arthroscopic full-thickness repair method can both significantly improve the shoulder pain and function of the patient, but there is no significant difference between the efficacy of the two surgical methods. The preoperative ASES score and whether biceps tenotomy was performed were independent risk factors for satisfactory postoperative efficacy in PTRCT patients with Ellman III injury.

Partial-thickness rotator cuff tears: a review of current literature on evaluation and management

Rotator cuff disease is a common cause of shoulder pain for which partial-thickness rotator cuff tears occupy a significant proportion. Such tears are often difficult to diagnose and manage in the general clinic setting. A review of the available literature from well-known databases was performed in this study to provide a concise overview of partial-thickness rotator cuff tears to aid physicians in their understanding and management.

The Incidence of Postoperative Shoulder Stiffness After Arthroscopic Rotator Cuff Repair: A Systematic Review

Rotator cuff tear (RCT) is a common shoulder condition frequently treated with arthroscopic rotator cuff repair (ARCR) after conservative interventions have failed. Postoperative shoulder stiffness (POSS) is a common complication after ARCR. The purpose of this study is to determine the incidence of POSS after ARCR in total and based on tear extent prior to ARCR. A systematic review was performed using PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Medical Literature Analysis and Retrieval System Online (MEDLINE), and ScienceDirect databases. The search terms were "rotator cuff repair" AND "arthrofibrosis" OR "postoperative shoulder stiffness." Articles were selected based on ARCR and the presence of POSS documentation. Twenty-five articles out of 284 articles met the final selection criteria after reviewing for patients who received ARCR. Out of all patients (n=9,373), 597 had POSS (6.4%). Out of the 2,424 patients with a specified tear pattern, 96 out of 1,862 (5.2%) patients with full-thickness tears and 58 out of 562 (10.3%) patients with partial-thickness tears had POSS after ARCR. Partial-thickness tears are associated with higher rates of POSS after ARCR as compared to full-thickness tears (p<0.001). Overall, POSS is a common complication after ARCR with an incidence of 6.4%, regardless of tear type. POSS is more common in patients who receive ARCR for partial-thickness RCT (10.3%) as compared to patients who receive ARCR for full-thickness RCT (5.2%). More research is needed to determine other factors impacting the incidence of POSS after ARCR.

Subscapularis tendon tears hidden by the medial biceps sling can be missed on arthroscopic examination

INTRODUCTION

To investigate (1) the prevalence of "hidden lesions" and "non-hidden lesions" of subscapularis tendon tears requiring repair during arthroscopic examination that would be missed by a 30° arthroscope, but could be identified by a 70° arthroscope, from the standard posterior portal and (2) the correlation of preoperative internal rotation weakness and findings of magnetic resonance imaging (MRI) indicating hidden lesions.

MATERIALS AND METHODS

We retrospectively examined 430 patients who underwent arthroscopic subscapularis repair between was initially nonvisible with a 30° arthroscope but became visible only with a 70° arthroscope from the standard posterior portal. The preoperative and intraoperative findings of the hidden lesion group (n = 82) were compared with those of the non-hidden lesion group (n = 348). 2016 and 2020. A hidden lesion was defined as a subscapularis tendon tear requiring repair that preoperative internal rotation weakness was assessed using the modified belly-press test. Preoperative MR images were reviewed using a systemic approach.

RESULTS

The prevalence of hidden lesions was 19.1% (82/430). No significant difference was found in preoperative internal rotation weakness between the groups. Preoperative MRI showed a significantly lower detection rate in the hidden lesion group than in the non-hidden group (69.5% vs. 84.8%; P = 0.001). The hidden lesions were at a significantly earlier stage of subscapularis tendon tears than the non-hidden lesions, as revealed by the arthroscopic findings (Lafosse classification, degree of retraction; P = 0.003 for both) and MR findings (muscle atrophy, fatty infiltration; P = 0.001, P = 0.005, respectively).

CONCLUSIONS

Among the subscapularis tears requiring repair, 19.1% could be identified by a 70° arthroscope, but not by a 30° arthroscope, through the posterior portal. The hidden lesions showed a significantly lower detection rate on preoperative MRI than the non-hidden lesions. Thus, for subscapularis tears suspected on preoperative physical examination, the 70° arthroscope would be helpful to avoid a misdiagnosis.

Transtendon Repair Under Switching-Scope Technique for Articular Partial-Thickness Rotator Cuff Tears

Partial-thickness rotator cuff tears are common diseases causing pain and disability. Among the different surgical methods, the transtendon repair technique is recommended due to its biomechanically superiority. However, this technique has a high learning curve and is time-consuming. In this Technical Note, we introduce a safer and more effective modified transtendon repair technique. Our switching-scope technique sets a switching stick into the glenohumeral joint through the posterior portal and is used as a guide for switching the arthroscope between the subacromial and articular spaces. This technique can reduce surgical time and overcome the disadvantage of vision limitation in articular-sided transtendon repair.

Diagnosis and Management of Partial Thickness Rotator Cuff Tears: A Comprehensive Review

Partial thickness rotator cuff tears (PRCTs) are a challenging disease entity. Optimal management of PRCTs continues to be controversial. Although advances in magnetic resonance imaging and ultrasonography have aided in early diagnosis, arthroscopic evaluation remains the benchmark for diagnosis. Conservative treatment is often the first line of management for most patients; however, evidence suggests that surgical intervention may limit tear progression and the long-term sequelae. Surgical decision making is driven by factors such as age, arm dominance, etiology, activity level, tear thickness, and tear location. Many surgical options have been described in the literature to treat PRCTs including arthroscopic débridement, transosseous, in situ repair techniques, and tear completion and repair. Biologic supplements have also become an attractive alternative to aid in healing; however, the long-term efficacy of these modalities is largely unknown. This article will provide a detailed review of the etiology and natural history of PRCTs, as well as diagnosis, and current management to guide clinical decision-making and formulate an algorithm for management of PRCTs for the orthopaedic surgeon.

Efficacy of threading lasso fixation in repairing partial articular supraspinatus tendon avulsion lesions: a retrospective study

Background

The partial articular supraspinatus tendon avulsion (PASTA) lesion repair remains a topic of debate. We have performed in situ repair of PASTA lesions using a potentially viable threading lasso fixation technique. This retrospective case series aimed to evaluate the clinical outcomes of PASTA lesion repair using threading lasso fixation. To the best of our knowledge, this is the first study to review this technique and its outcomes in terms of pain and upper extremity function.

Methods

Twenty-five patients with PASTA lesions who were treated with threading lasso fixation were reviewed. All patients were followed up for at least 1 year. Preoperative and follow-up data were retrospectively collected and reviewed. Clinical outcomes were assessed to evaluate the efficacy of the surgery.

Results

There were no postoperative complications. The average follow-up period was 25.7 (22–27) months. At the last follow-up, all patients underwent follow-up magnetic resonance imaging; only two cases showed a partially healed tendon and no case converted to full-thickness tear. Furthermore, shoulder pain decreased and mobility was recovered, with statistically significant differences in all scoring measures. Specifically, the mean visual analog scale score decreased from 5.4 ± 1.2 before surgery to 1.1 ± 0.8 at the last follow-up (t = 14.908, P < 0.01), and the mean American Shoulder and Elbow Surgeons Shoulder Assessment Form score improved significantly from 51.6 ± 6.4 to 89.3 ± 5.2 (t = 22.859, P < 0.01). Additionally, the mean University of California Los Angeles score improved from 17.8 ± 3.5 preoperatively to 32.3 ± 1.4 (t = 19.233, P < 0.01).

Conclusions

Arthroscopic repair using threading lasso fixation is a novel transtendinous technique for patients with partial articular supraspinatus tendon avulsion. Tendon integrity is preserved with this method, which may result in improved function. Overall, threading lasso fixation technique is an effective treatment.

Comparison of Arthroscopic Debridement and Repair in the Treatment of Ellman Grade II Bursal-side Partial-thickness Rotator Cuff Tears: A Prospective Randomized Controlled Trial

Objective

To compare the effects of arthroscopic debridement and repair in treating Ellman grade II bursal‐side partial‐thickness rotator cuff tears.

Methods

This is a single‐center, prospective, randomized controlled trial. From September 2017 to April 2019, 78 patients underwent arthroscopic debridement (35 patients) or repair (43 patients) due to Ellman grade II bursal‐side partial‐thickness rotator cuff tears. Twenty‐six men and 52 women were included in the study, with an average age of 56.31 years (range, 42 to 74 years). After the acromioplasty was formed, the debridement group only performed stump refreshing and surrounding soft tissue cleaning, while the repair group converted the partial tears into full‐thickness tears and then sutured them by single row or suture bridge technique. The visual analogue scale (VAS), Constant‐Murley shoulder (CMS), American Shoulder and Elbow Surgeons (ASES), and University of California, Los Angeles (UCLA) scores were used to evaluate clinical results preoperatively and at 6, 12, and 18 months postoperatively. Magnetic resonance imaging was used to assess the integrity of the rotator cuff, muscle atrophy, and fat infiltration.

Results

A total of 85 patients met the inclusion criteria and were randomly divided into the debridement group (41 patients) and the repair group (43 patients). During the 18‐month follow‐up period, a total of seven patients were lost to follow‐up. The functional scores of both groups were significantly improved: the VAS score decreased 5.06 and 4.63 in the debridement group (5.77 preoperative to 0.71 postoperative) and the repair group (5.49 to 0.86) (P < 0.05). Moreover, the CMS, ASES, UCLA scores increased 51.63, 58.24, 20.57 in debridement group (39.46 to 91.09, 34.14 to 92.38, 13.29 to 33.86), and increased 48.14, 60.53, 20.93 in repair group (43.63 to 91.77, 33.10 to 93.63, 12.58 to 33.51) (P < 0.05). No significant differences were found in functional scores between the two groups at 6, 12, and 18 months postoperatively (P > 0.05). The magnetic resonance imaging showed no re‐tears, and no difference was observed in the degree of muscle atrophy and fat infiltration between the two groups (P > 0.05). Except for four cases of shoulder stiffness, no other obvious surgery‐related complications were found.

Conclusion

For Ellman grade II bursal‐side partial‐thickness rotator cuff tears, both the debridement and repair groups achieved good results during 18‐month follow‐ups, with no difference between the two groups.

No Difference in Outcome Between Articular-Sided and Bursal-Sided Tears: Comparative Study With Minimum 2-Year Follow-Up of Arthroscopic Repairs in 104 Patients in a Single-Surgeon Series

PURPOSE

To evaluate and compare the functional outcomes after arthroscopic repair of bursal-sided versus articular-sided partial-thickness rotator cuff tears.

METHODS

We conducted a retrospective analysis of patients who had undergone arthroscopic tear completion and subsequent repair of symptomatic partial-thickness rotator cuff tears in a single institution from 2010 to 2015. Range of motion (ROM) (forward flexion and abduction), the pain score as measured on the Numeric Pain Rating Scale, and outcome scores (Constant-Murley score, University of California, Los Angeles shoulder score, and Oxford Shoulder Score) were calculated preoperatively and at 1 year and 2 years postoperatively. The delta difference was calculated for each outcome parameter at the respective follow-up points as the difference from the preoperative baseline score.

RESULTS

A total of 104 patients were included. All tears involved the supraspinatus tendon and did not exceed 2 cm. Of the patients, 65 had an articular-sided tear (AST) whereas 39 had a bursal-sided tear (BST). The mean age of the patients was 53.4 years in the AST group and 55.8 years in the BST group. The AST and BST groups did not differ preoperatively in terms of age, sex, and the measured outcome parameters. Postoperatively, the patients in both groups achieved statistically significant improvement in pain relief and functional outcomes at 2 years. No statistically significant difference was observed between the 2 groups in terms of the delta-difference outcomes in ROM in forward flexion (P = .781) or abduction (P = .348), pain score (P = .187), Constant-Murley score (P = .186), University of California, Los Angeles shoulder score (P = .911), and Oxford Shoulder Score (P = .186) at 2 years.

CONCLUSIONS

Partial-thickness rotator cuff tears treated with arthroscopic tear completion and subsequent repair achieved good outcomes in terms of ROM, functional outcomes, and pain relief at 2 years. There was no difference in outcomes regardless of whether the location of the tear was articular sided or bursal sided.

LEVEL OF EVIDENCE

Level III, retrospective comparative study.

Outcomes and Tendon Integrity After Arthroscopic Treatment for Articular-Sided Partial-Thickness Tears of the Supraspinatus Tendon: Results at Minimum 2-Year Follow-Up

Background:

The best surgical treatment option for symptomatic moderate- to high-grade articular-sided partial-thickness rotator cuff tears (PTRCTs) is still controversial.

Purpose/Hypothesis:

The purpose of this study was to evaluate patient-reported and clinical outcomes and tendon integrity after arthroscopic debridement or repair for PTRCTs at a minimum of 2 years postoperatively. We hypothesized that the overall outcomes would be positive, showing pain relief, good shoulder function, and high tendon integrity.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

We evaluated 30 patients (16 men, 14 women; mean age, 51 years) who underwent arthroscopic treatment for symptomatic PTRCTs (Ellman grades 2 and 3). Debridement was performed in 15 patients, and arthroscopic tendon repair was performed in the remaining 15 patients. Patients completed the Constant score; American Shoulder and Elbow Surgeons (ASES) shoulder score; Western Ontario Rotator Cuff Index; Simple Shoulder Test; and visual analog scale (VAS) for pain, function, and satisfaction. In addition, patients were examined clinically (range of motion, impingement tests, rotator cuff tests, and tests for the long head of the biceps tendon), and morphologic assessment of rotator cuff integrity was performed using direct magnetic resonance arthrography and was classified according to Sugaya.

Results:

The mean follow-up period was 55 months. The patient-reported outcome measures showed high patient satisfaction, reduction in persistent pain, and good shoulder function. Linear regression analysis showed that the debridement group had significantly better results on the Constant (bias-corrected and accelerated [BCa] 95% CI, 4.20-26.30), ASES (BCa 95% CI, 5.24-39.26), and VAS (pain: BCa 95% CI, 0.13-3.62; function: BCa 95% CI, 1.04-4.84; satisfaction: BCa 95% CI, 0.14-6.28) scores than did the repair group. At follow-up, there was no significant difference between the groups in clinical testing results. Good supraspinatus tendon integrity was seen in most patients: Sugaya classification grade 1 in 13 patients, grade 2 in 11 patients, and grade 3 in 6 patients.

Conclusion:

Midterm results after arthroscopic debridement and repair for PTRCTs showed high patient satisfaction, good shoulder function, and high tendon integrity for both procedures. Patients who underwent arthroscopic debridement had higher Constant, ASES, and VAS scores compared with patients who underwent tendon repair.

Arthroscopic Single Lateral Row Repair Technique for Small Rotator Cuff Tears

Small symptomatic rotator cuff tears are a common problem seen by orthopaedic surgeons. Arthroscopic repair has been shown to have favorable outcomes for these lesions. There is as yet no consensus on the ideal technique for the arthroscopic repair of small rotator cuff tears. We present a single lateral row technique for the repair of such lesions, which we believe to be reproducible and effective, that achieves good approximation of the tear while reducing the chance of suture cutouts.

A comparative study of arthroscopic débridement versus repair for Ellman grade II bursal-side partial-thickness rotator cuff tears

HYPOTHESIS

We aimed to report the clinical outcomes of arthroscopic débridement vs. repair for Ellman grade II bursal-side partial-thickness rotator cuff tears.

METHODS

Patients who presented with Ellman grade II bursal-side partial-thickness rotator cuff tears from September 2015 to August 2017 were included. On the basis of preoperative findings and patient preference, 20 patients underwent débridement whereas 26 underwent arthroscopic repair. The visual analog scale (VAS), Constant-Murley shoulder, American Shoulder and Elbow Surgeons, and University of California-Los Angeles scores were assessed. Magnetic resonance imaging and B-mode ultrasonography were performed preoperatively and at 6, 12, and 24 months postoperatively.

RESULTS

All 46 patients were available throughout follow-up. At 2 years postoperatively, the VAS score had improved from 6.42 ± 1.56 to 0.65 ± 0.51 in the débridement group and from 6.26 ± 1.32 to 0.75 ± 0.42 in the repair group. The VAS score differed significantly between the 2 groups at 6 months postoperatively. All patient-reported outcomes improved in both groups. The American Shoulder and Elbow Surgeons score (P = .009), Constant-Murley shoulder score (P = .014), and University of California-Los Angeles score (P = .030) differed significantly between the 2 groups (higher in the débridement group) at 6 months postoperatively. Finally, 44 patients having intact tendon repairs with no interval worsening of partial-thickness tears underwent postoperative scheduled magnetic resonance imaging and B-mode ultrasonography examinations.

CONCLUSION

Arthroscopic débridement and repair of Ellman grade II bursal-side partial-thickness rotator cuff tears achieved comparable clinical scores and low retear rates during 2 years of follow-up. However, débridement achieved better results, especially within 6 months postoperatively, and achieved a favorable prognosis up to 2 years postoperatively.

Partial articular supraspinatus tendon avulsion: Should we repair? A systematic review of the evidence

INTRODUCTION

Partial articular sided rotator cuff tears are described as being a common cause of shoulder pain and to have a significant impact of patient quality of life. The natural history of partial articular supraspinatus tendon avulsion lesions is not clearly defined and there is limited evidence to determine optimal management.

AIMS

To perform a systematic review of the literature regarding the evidence for partial articular supraspinatus tendon avulsion repair and to determine whether there is any difference between operative and non-operatively managed patients.

METHODS

Conventional and grey literature were searched with defined terms to identify studies in human adults concerning management of partial articular sided supraspinatus avulsions.

RESULTS

Out of 86 papers identified by the search terms, 28 were deemed eligible for review including 1966 shoulders. 4/28 papers were of level I-II evidence but all were comparing techniques. 4/28 papers were biomechanical cadaveric studies, assessing strength of repair and effect on stability. The remaining 20 studies were level IV-V evidence and consisted of case series and technical notes identifying varying techniques of repair and their outcomes.

CONCLUSION

Current literature suggests that all techniques used to repair partial articular supraspinatus tendon avulsion lesions give increased functional scores and reduced pain. However, this represents a heterogeneous group of patients with variable degrees of tear and is not reproducible. There are limited controlled studies to determine whether partial articular supraspinatus tendon avulsion lesions require repair. Current classification systems represent a single plane and are open to user variation. No evidence exists to determine which tears are stable and which may progress.

Arthroscopic repair of partial-thickness articular surface rotator cuff tears: single-row transtendon technique versus double-row suture bridge (transosseous equivalent) fixation: results from a prospective randomized study

BACKGROUND

The purpose of this prospective study was to compare the clinical and structural findings following the arthroscopic repair of partial-thickness (exceeding 50%) articular-sided rotator cuff tears using either a single-row or a double-row suture bridge fixation.

MATERIALS AND METHODS

Fifty patients were included in this study. The patients were randomly placed into two groups: 25 underwent the single-row (Group I) and 25 a double-row suture bridge fixation (Group II). The clinical outcomes were assessed using ASES and Constant shoulder scores, both preoperatively and at the end of follow-up. The pain level was evaluated using the visual analogue scale (VAS), preoperatively, at 6 months and at the end of follow-up. All patients underwent preoperative MRI to identify the rotator cuff tear, and postoperatively at 12 months to evaluate tendon integrity.

RESULTS

The average follow-up was 32.5 months. The mean ASES scores increased from 35.9 to 96.7 in Group I and from 35.3 to 93.4 in Group II; the mean Constant shoulder scores increased from 55.6 to 97.8 in Group I and from 57.5 to 97.3 in Group II. There were no significant differences between the two groups. The average preoperative pain level decreased from 7.4 to 3 at 6 months and to 0.4 at the end of the Group I; and from 7.6 to 3 at 6 months and 0.8 in Group II. There was no significant difference between the two groups. At 12 months, the MRI assessments showed two retears in Group I (8%) and one retear in Group II (4%).

CONCLUSION

Arthroscopic repair of partial-thickness articular rotator cuff tears that exceed 50% of tendon thickness with a single-row transtendon repair or double-row suture bridge provides functional improvement and pain relief regardless of the repair technique used. There were no differences in clinical results between both techniques.

LEVEL OF EVIDENCE

Level II; prospective comparative study.

Repairing PASTA Lesions Without Violation of the Rotator Cuff

Partial-thickness articular-sided rotator cuff tears are a common cause of shoulder pain in adults. Although partial rotator cuff tears have a high prevalence, there is still controversy over their proper surgical treatment. Different surgical procedures have been suggested when partial tears involve the articular side of the rotator cuff, such as arthroscopic debridement of the tear with or without acromioplasty, tear completion and repair, and transtendinous in situ repair. Although multiple repair techniques have been described, significant clinical data to definitively support one technique over the others are currently lacking. We describe an arthroscopic technique for repair of a partial articular supraspinatus tendon avulsion that avoids the transtendinous insertion of suture anchors to preserve the tendon integrity.

In situ repair of partial-thickness rotator cuff tears: a critical analysis review

After failed conservative management, operative intervention is typically indicated for patients with partial-thickness rotator cuff tears (PTRCTs) with persistent pain and disability symptoms.

For PTRCTs involving < 50% of the tendon thickness, debridement with or without acromioplasty resulted in favourable outcomes in most studies.

For PTRCTs involving > 50% of the tendon thickness, in situ repair has proven to significantly improve pain and functional outcomes for articular and bursal PTRCTs.

The few available comparative studies in the literature showed similar functional and structural outcomes between in situ repair and repair after conversion to full-thickness tear for PTRCTs.

Most non-overhead athletes return to sports at the same level as previous to the injury after in situ repair of PTRCTs. However, rates of return to preinjury level of competition for overhead athletes have been generally poor regardless of the utilized technique.

During long-term follow-up, arthroscopic in situ repair of articular and bursal PTRCTs produced excellent functional outcomes in most patients, with a low rate of revision.

Arthroscopic knotless single-row repair preserving full footprint versus tear completion repair for partial articular-sided rotator cuff tear

BACKGROUND

The comparison of clinical outcomes of arthroscopic footprint-preserving knotless single-row repair with the tear completion repair technique for articular-sided partial-thickness rotator cuff tears (PTRCTs) remains unclear.

METHODS

A total of 68 patients diagnosed with articular-sided PTRCTs who underwent rotator cuff repair between December 2014 and June 2015 were included. Of the 68 patients, 30 received footprint-preserving knotless single-row repair (group 1) and 38 received the tear completion repair technique (group 2). Preoperative and postoperative assessments were compared.

RESULTS

Both groups had significantly improved American Shoulder and Elbow Surgeons (ASES) scores (group 1: 48.2 preoperatively to 81.9 postoperatively, p < 0.001; group 2: 47.1 preoperatively to 84.9 postoperatively, p < 0.001) and visual analog scale (VAS) pain score (group 1: 6.0 preoperatively to 0.93 postoperatively, p < 0.001; group 2: 6.1 preoperatively to 1.1 postoperatively, p < 0.001), showing that the two procedures significantly improved postoperative shoulder function. No significant differences were shown in ASES score or VAS pain score between the two groups ( p > 0.05). The mean operation time was significantly shorter in group 1 with an average of 48.1 min than in group 2 with an average of 60.4 min ( p < 0.001).

CONCLUSIONS

Footprint-preserving knotless single-row repair obtains similar clinical results compared to tear completion repair in the treatment of articular-sided PTRCTs. Footprint-preserving knotless single-row repair may be a convenient choice for the treatment of articular-sided PTRCTs. Randomized controlled studies are needed to investigate whether the footprint-preserving knotless single-row repair yields better long-term outcomes through the protection of the bursal cuff and restoration of the healthy footprint.

Predictors of allocation to surgery in patients older than 50 years with partial-thickness rotator cuff tear

BACKGROUND

The purpose of this study was to determine the predictive factors for allocation to surgery in patients older than 50 years with symptomatic chronic partial-thickness rotator cuff tear (PTRCT).

METHODS

Patients older than 50 years with a confirmed diagnosis of unilateral isolated PTRCT were included in this retrospective study. In the minimum follow-up of 2 years, eventual allocation to surgical or nonsurgical treatment was determined individually. Patients who underwent surgery were defined as failed conservative management and allocation to surgery. Data pertaining to patients' demographics, functional comorbidity index values, duration of symptoms, and American Shoulder and Elbow Surgeons scores were collected from our medical records. Tear side and Ellman classification, subacromial spur, and acromiohumeral intervals were also noted. A regression analysis was performed to determine the major predictors of allocation to surgery.

RESULTS

There were 202 patients with a mean age of 62 years in group I (no-surgery group) and 70 patients with a mean age of 57 years in group II (surgery group). The mean age and functional comorbidity index values were significantly higher in group I than in group II (P < .001 and P < .001, respectively). Bursal-sided tears were significantly more common in group II (P = .026). According to the findings of regression analysis, tear side and functional comorbidity index were the major predictors of allocation to surgery (P = .015 and P < .001, respectively).

CONCLUSION

Our study results indicate that in patients older than 50 years with PTRCTs, those with fewer comorbidities and bursal-sided PTRCTs were significantly more likely to undergo surgery.

Long-Term Outcomes After In Situ Arthroscopic Repair of Partial Rotator Cuff Tears

PURPOSE

To analyze clinical outcomes, return to sports, and complications in a series of patients with painful partial-thickness rotator cuff tears treated with arthroscopic in situ repair with suture anchors who had a minimum of 8 years of follow-up.

METHODS

Sixty-two patients who had undergone an arthroscopic in situ repair for partial-thickness rotator cuff tears were evaluated. All injuries involved the supraspinatus tendon. Clinical assessment consisted of glenohumeral range-of-motion measurement and the American Shoulder and Elbow Surgeons score. Pain was rated by using a visual analog scale. We assessed return to sports and the level of performance achieved after surgery. Postoperative complications were also assessed.

RESULTS

Mean age was 52.4 years (range, 32 to 67 years), and mean duration of follow-up was 10.4 years (range, 8 to 12 years). All active range-of-motion parameters improved significantly (P < .0001). The American Shoulder and Elbow Surgeons score improved from 45.6 to 85.1; and the visual analog scale scores improved from 6.4 to 1.6 (P < .0001). Thirty patients participated in sports before injury: 21 were recreational athletes and 9 were competitive athletes. Twenty-six (87%) were able to return to sports, and 24 (80%) returned to the same level they had achieved before injury. No significant difference regarding functional outcomes or return to sports was found between patients with articular-sided tears and those with bursal-sided tears. No revision surgeries were performed. Three patients had postoperative adhesive capsulitis that responded favorably to physical therapy.

CONCLUSIONS

During long-term follow-up, arthroscopic in situ repair of partial-thickness rotator cuff tears produces excellent functional outcomes in more than 80% of patients, and revision rates are low. Most patients return to their chosen sport at the same level they had achieved before injury. The results are equally favorable for articular-sided and bursal-sided tears.

Functional outcomes and repair integrity after arthroscopic repair of partial articular supraspinatus tendon avulsion

INTRODUCTION

Partial-thickness rotator cuff tears are a common cause of shoulder pain and disability. Arthroscopic repair is an effective treatment for partial articular supraspinatus tendon avulsion (PASTA) lesions, and transtendon repair and completion of the tear and repair are the surgical techniques commonly used to treat such lesions. Our aim was to retrospectively evaluate the minimum 24-month clinical and radiological results of PASTA.

MATERIALS AND METHODS

Patients suffering from PASTA lesion who underwent arthroscopic repair with a minimum 24-month follow-up were included in this study. The Constant and Murley score (CMS) was used to assess the patients' functionality pre- and postoperatively. The postoperative patient assessment included the simple shoulder test (SST). Postoperative tendon integrity was evaluated by ultrasound examination.

RESULTS

151 patients (153 shoulders) were retrospectively evaluated 73.9 (24-142) months after a completion-repair (94 cases) or transtendon repair (59 cases) of a PASTA lesion. The CMS significantly improved from 47.7 (22-63) preoperatively to 84.2 (62-100) postoperatively (p < 0.001). The mean postoperative SST score was 10.1 (5-12), and 95% of patients were satisfied with the surgery. No significant differences were noted between the two techniques in terms of postoperative CMS, SST score and satisfaction. Seventy-four and 43 cases treated with completion and repair and transtendon repair, respectively, performed ultrasound examination 66.1 (24-142) months after surgery. The overall retear rate was 13.7%, supraspinatus retears were observed in ten shoulder subjected to completion and repair (13.5%) and six shoulders subjected to transtendon repair (13.9%), and no significant differences were noted between the two techniques as for CMS (p = 0.896), SST (p = 0.973), satisfaction (p = 0.621) and retear (p = 0.999). Males and younger patients had a higher postoperative CMS (p values < 0.001), and SST score (p < 0.001 and p = 0.038, respectively).

CONCLUSIONS

Arthroscopic repair of PASTA lesion achieves high rates of repair integrity regardless of repair type and high levels of functional recovery and patient satisfaction 6 years after surgery.

Return to Sports After in Situ Arthroscopic Repair of Partial Rotator Cuff Tears

PURPOSE

To evaluate return to sport, clinical outcomes, and complications in a series of athletes with painful partial-thickness rotator cuff tears treated with the arthroscopic in situ repair with a minimum 2-year follow-up.

METHODS

Retrospective case series. Seventy-two patients who had undergone an arthroscopic in situ repair for partial-thickness rotator cuff tears were evaluated. We assessed return to sport and the level achieved after surgery. Clinical assessment consisted of glenohumeral range of motion measurement and the American Shoulder and Elbow Surgeons score. Pain was recorded using a visual analog scale. Postoperative complications were also assessed.

RESULTS

The mean age was 42.2 years (range, 21-66 years), and the mean follow-up was 54 months (range, 24-113 months). Sixty-one patients (87%) were able to return to sports. Fifty-six patients (80%) returned to the same level they had previous to the injury. The mean interval between surgery and return to competition was 5.6 months. The final functional outcomes were related neither to the type of sports nor to the level of competition before the injury. All active range of motion parameters improved significantly (P < .0001). The American Shoulder and Elbow Surgeons score improved from 43.3 to 88.1, and the visual analog scale scores improved from 6.1 to 1.2 (P < .0001). No significant difference regarding return to sports or functional outcomes was found between articular and bursal-sided tears. Only 5 patients developed a postoperative adhesive capsulitis that responded to physical therapy.

CONCLUSIONS

In patients with partial-thickness rotator cuff tears, arthroscopic in situ repair resulted in excellent functional outcomes, with most of the patients returning to sport and at the same level they had before injury. The results were equally favorable in articular and bursal tears.

Transtendinous repair of partial articular sided supraspinatus tears is associated with higher rates of stiffness and significantly inferior early functional scores than tear completion and repair: A systematic review

INTRODUCTION

Transtendon repair (TTR) and tear completion and repair (TCR) are common repair techniques for partial thickness rotator cuff tears (PTRCTs). Previous systematic reviews have not demonstrated any advantage of either but have not specifically addressed early recovery.

AIM

To compare the outcomes of these two techniques in treating PTRCTs with respect to post-operative stiffness, delay in functional recovery and re-tear rates.

MATERIAL AND METHODS

A systematic review of the Medline and EMBASE database was performed in accordance with the PRISMA guidelines. Both cases series and comparative studies reporting functional outcomes, post-operative stiffness or re-tear rate after either TTR or TCR for PTRCTs were included.

RESULTS

The search strategy identified 21 studies (n=797); 4 comparative studies (n=214), 15 TTR (n=511) and 2 TCR case series (n=72). All four comparative studies included were randomised controlled trials. One RCT reported early outcomes and demonstrated significantly slower recovery in the TTR group at 3 months (ASES p=0.037, Constant score p=0.019 and pain p=0.001). Similarly, data from the case series suggested that the rate of post-operative stiffness was higher in the TTR group. All comparative studies demonstrated no significant difference at final follow up in terms of pain, range of motion or functional score.

DISCUSSION

The results of this systematic review suggest that transtendinous repairs are associated with more pain and worse function during the first 3 months. This suggests that tear completion and repair should be the preferred option, as comparative studies do not demonstrate any long-term advantage of transtendinous repair.

Do Articular-Sided Partial-Thickness Rotator Cuff Tears After a First-Time Traumatic Anterior Shoulder Dislocation in Young Athletes Influence the Outcome of Surgical Stabilization?

Background:

Because of the high risk for redislocations after a first-time traumatic anterior shoulder dislocation with conservative treatment, recent publications have recommended early arthroscopic intervention, especially for young athletes. Concomitant rotator cuff tendon damage may occur when the shoulder dislocates; however, its presence and influence on clinical results have not been well described in this patient category.

Hypothesis:

In opposition to current opinion, a substantial number of articular-sided partial-thickness rotator cuff tears (APTRCTs) would be found at surgery after a first-time traumatic anterior shoulder dislocation in young athletes. However, the impact of these injuries on 2-year postoperative results would be negligible.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

Sixteen male patients (mean age, 21 years [range, 16-25 years]) with a first-time traumatic anterior shoulder dislocation without bony Bankart lesions were included in this study. The indications for surgical treatment were age less than 25 years and being active in collision or contact sports at a competitive level. Arthroscopic surgery was performed at a mean 7.8 days (range, 2-14 days) after injury. Rowe and American Shoulder and Elbow Surgeons (ASES) scores as well as range of motion were evaluated at a minimum 2 years after an arthroscopic Bankart procedure, and a comparison of the clinical results between patients with and without APTRCTs was conducted.

Results:

An anterior-inferior capsulolabral injury was found in all patients. There were no bony Bankart lesions. An APTRCT was found in 9 of the 16 patients. At 2 years after surgical treatment, there were no significant differences between the patients with and without APTRCTs in terms of the Rowe score (90.0 and 87.1, respectively; P = .69) and ASES score (94.6 and 90.4, respectively; P = .67).

Conclusion:

APTRCTs were found in the superior part of the shoulder joint after a first-time traumatic anterior shoulder dislocation in a majority of young male athletes treated with surgical stabilization. There were no significant differences found between patients with and without APTRCTs in terms of the Rowe and ASES scores at 2 years after surgical treatment.

Transtendon repair in partial articular supraspinatus tendon tear

INTRODUCTION

Partial thickness rotator cuff tears (PTRCTs) are common, with an incidence between 17% and 37%, and a high prevalence in throwing athletes. Different surgical procedures are suggested when partial tears involve the articular portion of the rotator cuff, including arthroscopic debridement of the tear, debridement with acromioplasty, tear completion and repair, and lately transtendon repair. This systematic review describes the transtendon repair and examines indications, contraindications, complications and clinical outcome.

SOURCE OF DATA

We identified clinical studies listed in the Pubmed Google Scholar, CINAHL, Cochrane Central and Embase Biomedical databases in English and Italian concerning the clinical outcomes following treatment of partial articular supraspinatus tendon tear using transtendon surgical repair.

AREAS OF AGREEMENT

Eighteen studies fulfilled our inclusion criteria. All were published between 2005 and 2016, three were retrospective, and 15 prospective. The total number of patients was 507 with a mean age of 50.8 years.

AREAS OF CONTROVERSY

Tear completion and repair and transtendon repair alone produce similar results.

GROWING POINTS

Transtendon surgical repair allows to obtain good-excellent results in the treatment of partial articular supraspinatus tendon tears.

AREAS TIMELY FOR DEVELOPING RESEARCH

Further studies are needed to produce clear guidelines in the treatment of partial articular supraspinatus tendon tears.

Editorial Commentary: Your Surgical "Tool Box" Just Got a Little Bit Bigger

There is currently no "gold standard" for the surgical repair of a partial-thickness rotator cuff tear. Ranalletta et al. have made a meaningful contribution to the orthopaedic literature with this study that reports the clinical outcomes of 80 patients who underwent arthroscopic transtendon repair of high-grade, articular-sided partial-thickness rotator cuff tears. At a mean follow-up of 62 months, they noted significant improvement in pain, range of motion, and a number of objective shoulder outcome measures. Perhaps most importantly, 92.5% rated their shoulder as "good" or "excellent." Unfortunately, we cannot definitively state whether or not these repairs actually healed given the lack of postoperative imaging, nor do we know the actual depth of these partial tears that can be difficult to objectively quantify. Despite these shortcomings, arthroscopic surgeons who treat rotator cuff disorders will be able to use this information in treating their patients irrespective of their preferred surgical technique. Future studies are needed to definitively determine which repair method, if any, is better.
