Costs, Complications, and Reoperations Associated With Primary Arthroscopic Rotator Cuff Repair With or Without Acromioplasty and/or Biceps Tenodesis

Improved Clinical Outcomes After Partial Repair and In Situ Biceps Tenodesis for the Treatment of Massive Irreparable Rotator Cuff Tears

PURPOSE

To present the short-term outcomes of arthroscopic in situ biceps tenodesis combined with partial rotator cuff repair in patients with massive irreparable rotator cuff tears (MIRCTs) and minimal arthritis.

METHODS

A retrospective review was conducted using prospectively maintained institutional databases to identify patients who had undergone a partial rotator cuff repair with in situ biceps tenodesis between March 2017 and December 2022. Patients were included if they (1) were diagnosed pre- or intraoperatively with MIRCT and (2) had complete preoperative and minimum 1-year postoperative patient-reported outcome measures.

RESULTS

Thirty-nine patients met the eligibility criteria and were included for analysis. The mean age of the study participants was 65 ± 7 years (range, 46-76) with 76.9% (n = 30) being male. The average follow-up was 21 ± 12 months (range, 12-58). Patients experienced significant improvement in visual analog scale for pain (VAS), American Shoulder and Elbow Surgeons (ASES) score, and subjective assessment numeric evaluation (SANE) score (P < .001 for all comparisons). The pre- to postoperative improvement was 3.1 ± 2.3 for VAS, 27.5 ± 20.6 for ASES, and 31.3 ± 24.8 for SANE. Postoperatively, the average scores for VAS, ASES, and SANE were 1.3 ± 1.5, 79.5 ± 17.0, and 69.6 ± 20.1, respectively. Twenty-six patients (66.7%) achieved the minimal clinically important difference (MCID) for VAS, 33 patients (84.6%) achieved the MCID for ASES, and 30 patients (76.9%) achieved the MCID for SANE.

CONCLUSIONS

Partial rotator cuff repair with in situ biceps tenodesis is an effective treatment for MIRCT, leading to significant improvements in patient-reported outcome and range-of-motion measures compared to preoperative conditions.

Concomitant Biceps Tenodesis Does Not Compromise Arthroscopic Rotator Cuff Repair Outcomes

PURPOSE

To compare outcomes of patients who underwent rotator cuff repair (RCR) with concomitant biceps tenodesis with those who underwent an isolated RCR.

METHODS

Exclusion criteria included previous ipsilateral shoulder surgery, irreparable rotator cuff tears, rotator cuff arthropathy, calcific tendinitis, adhesive capsulitis requiring a capsular release, or advanced osteoarthritis of the glenohumeral joint. Patients were indicated for biceps tenodesis if they had any degree of tendon tearing, moderate-to-severe tenosynovitis, instability, or a significant degenerative SLAP tear. Primary outcome measures included American Shoulder and Elbow Surgeons score, Simple Shoulder Test, EuroQoL 5-Dimension 5-Level visual analog scale, EuroQoL 5-Dimension 5-Level, and a site-specific questionnaire, which focused on surgical expectations, satisfaction, and complications. Multivariate analysis of variance to analyze descriptive statistics and determine significant differences between the patient groups for subjective and objective outcome measures were performed.

RESULTS

There were no significant differences for pain/visual analog scale (0.34 ± 0.09 vs 0.47 ± 0.09, P = .31), American Shoulder and Elbow Surgeons score (96.69 ± 0.87 vs 94.44 ± 0.91, P = .07), and Simple Shoulder Test (11.42 ± 0.17 vs 10.95 ± 0.18, P = .06) between the RCR with concomitant biceps tenodesis and isolated RCR at a minimum of 2 years' postoperatively. This is despite the RCR with concomitant biceps tenodesis group having significantly larger rotator cuff tears (4.25 ± 0.30 cm2 vs 2.80 ± 0.32 cm2, P = .001) than the isolated RCR group.

CONCLUSIONS

This study revealed that concomitant biceps tenodesis does not compromise outcomes when compared with an isolated RCR at 2-year follow-up, despite this group having larger rotator cuff tears.

The Effect of Concomitant Biceps Tenodesis on Revision Surgery Rates After Primary Rotator Cuff Repair

INTRODUCTION

We aimed to use a national database to compare the 4-year revision surgery rates after rotator cuff repair (RCR) in patients with concomitant biceps tenodesis (BT) versus those without BT.

METHODS

A retrospective cohort analysis was conducted using the PearlDiver database from 2015 to 2017. Patients undergoing primary open and arthroscopic RCR with and without BT were identified. Demographic variables, 90-day complications, and 2- and 4-year revision surgery rates were analyzed, and a multivariable logistic regression was conducted.

RESULTS

Of the 131,155 patients undergoing RCR, 24,487 (18.7%) underwent concomitant BT and 106,668 (81.3%) did not. After controlling for comorbidities and demographics, patients with concomitant BT were associated with lower odds of all-cause revision (OR; P-value [0.77; P < 0.001]), revision BT (0.65; P < 0.001), revision RCR (0.72; P < 0.001), and shoulder arthroplasty (0.81; P = 0.001) within 4 years when compared with those without concomitant BT.

DISCUSSION

In our analysis, patients undergoing primary RCR with concomitant BT had 35% reduced odds of revision BT and 23% reduced odds of any all-cause revision within 4 years when compared with those without concomitant BT. This suggests that tenodesis at the time of primary RCR may be associated with a reduction in the utilization of ipsilateral shoulder revision surgery rates.

Clinical outcomes of rotator cuff repair with subacromial bursa reimplantation: a retrospective cohort study

Background

The subacromial bursa has been found to be a rich, local, source of mesenchymal stem cells but is removed for visualization during rotator cuff repair. Reimplantation of this tissue may improve rotator cuff healing. The purpose of this study is to evaluate clinical outcomes of rotator cuff repair with and without subacromial bursa reimplantation.

Methods

Patients aged 37-77 with a full-thickness or near full-thickness supraspinatus tears underwent arthroscopic transosseous-equivalent double row rotator cuff repair. In patients prior to July 2019, the subacromial bursa was resected for visualization, and discarded. In patients after July 2019, the subacromial bursa was collected using a filtration device connected to an arthroscopic shaver and reapplied to the bursal surface of the tendon at the completion of the rotator cuff repair. Rotator cuff integrity was evaluated via magnetic resonance imaging on bursa patients at 6 months postoperatively. Minimum 18-month clinical outcomes (Single Assessment Numeric Evaluation, American Shoulder and Elbow Surgeons, patient satisfaction) were compared between bursa and nonbursa cohorts.

Results

A total of 136 patients were included in the study (control n = 110, bursa n = 26). Preoperative demographics and tear characteristics were not different between groups. Average follow-up was significantly longer in the control group (control: 3.2 ± 0.7 years; bursa: 1.8 ± 0.3 years; P < .001). The control group showed a significantly higher Single Assessment Numeric Evaluation score (control: 87.9 ± 15.8, bursa: 83.6 ± 15.1, P = .037) that did not meet minimum clinically important difference. The American Shoulder and Elbow Surgeons and patient satisfaction scores were similar between the groups. Symptomatic retears were not significantly different between groups (control: 9.1%, bursa 7.7%, P = .86). Seven patients in the control group underwent reoperation (6.4%), compared to 0 patients in the bursa group (0%, P = .2). Six-month postoperative magnetic resonance images obtained on bursa patients demonstrated 85% rotator cuff continuity (n = 17/20) as defined via Sugaya classification.

Conclusion

Augmentation of rotator cuff repair with bursal tissue does not appear to have negative effects, and given the accessibility and ease of harvest of this tissue, further research should be performed to evaluate its potential for improved tendon healing or clinical outcomes.

Resorbable Bioinductive Collagen Implant Is Cost Effective in the Treatment of Rotator Cuff Tears

Purpose

This study was conducted to investigate whether the use of resorbable bioinductive collagen implant (RBI) in addition to conventional rotator cuff repair (conventional RCR) is cost-effective when compared to conventional RCR alone, in the treatment of full-thickness rotator cuff tears (FT RCT).

Methods

We developed a decision analytic model to compare the expected incremental cost and clinical consequences for a cohort of patients with FT RCT. The probabilities for healing or failure to heal (retear) were estimated from the published literature. Implant and healthcare costs were estimated from a payor's perspective in 2021 U.S. prices. An additional analysis included indirect cost estimations (e.g., productivity losses). Sensitivity analyses explored the effect of tear size, as well as the impact of risk factors.

Results

The base case analysis demonstrated that resorbable bioinductive collagen implant + conventional rotator cuff repair results in incremental costs of $232,468 and an additional 18 healed RCTs per 100 treated patients over 1 year. The estimated incremental cost-effectiveness ratio (ICER) is $13,061/healed RCT compared to conventional RCR alone. When return to work was included in the model, RBI + conventional RCR was found to be cost saving. Cost-effectiveness improved with tear size with the largest benefit seen in massive tears compared to large tears, as well as patients at higher risk of retearing.

Conclusions

This economic analysis demonstrated that RBI + conventional RCR delivered improved healing rates at a marginal increase in costs when compared to conventional RCR alone and is, therefore, cost-effective in this patient population. Considering indirect costs, RBI + conventional RCR resulted in lower costs compared to conventional RCR alone and is, therefore, deemed to be cost saving.

The impact of external beam radiation therapy on shoulder surgical outcomes: a case series study

HYPOTHESIS

External beam radiation therapy (XRT) is a commonly used treatment adjunct in patients with breast cancer and is known to cause soft tissue dysfunction. However, data on XRT as a preoperative risk factor for shoulder surgery is limited. The purpose of this study was to assess whether prior history of breast cancer treated with XRT has an impact on surgical complications or outcomes. We hypothesize that patients treated with XRT will have a higher rate of surgical complications and lower outcomes.

METHODS

A 20-year retrospective chart review across a large, academic health care system was performed. Inclusion criterion comprised any patient with history of breast cancer of the upper-outer or axillary region treated with XRT. Patients also must have undergone a surgical procedure to the ipsilateral shoulder with at least 1-year postoperative follow-up. Patients were stratified by demographics, hand dominance, and surgery type. Postoperative outcomes including range of motion (ROM) and visual analog scale (VAS) scores for pain were also collected.

RESULTS

Eighteen patients were identified (100% female) with an average age of 66.3 years (standard deviation 10.5 years). Ten shoulders underwent rotator cuff repair (RCR), 4 total shoulder arthroplasty (TSA), 3 reverse shoulder arthroplasty (RSA), and 1 arthroscopic superior labrum anterior to posterior (SLAP) repair. Four patients treated with RCR (40%) experienced postoperative complications related to their procedure. These included scapular winging, adhesive capsulitis, stiffness, and one retear. Two patients treated with shoulder arthroplasty (28.6%) experienced postoperative complications that included lymphedema and periprosthetic fracture following a mechanical fall in one RSA patient and periprosthetic infection in a TSA patient. ROM across all groups improved, most significantly in forward flexion and internal rotation among RCR patients (P < .001). Furthermore, a statistically significant improvement in VAS scores was achieved in each group (6.2 ± 2.14 preoperation, 1.06 ± 1.75 postoperation; P < .001).

CONCLUSION

When compared to national averages, complication rates in our cohort were higher (40% vs. 10%-17% in RCR patients and 28.6% vs. 4%-14% in arthroplasty patients). On further scrutiny, many of these complications were independent of a history of XRT and many resolved with appropriate therapy. Most importantly, functional outcomes as measured by ROM and pain scores showed appropriate improvement consistent with normal populations without history of XRT. Thus, our results suggest that performing shoulder surgery after ipsilateral XRT for breast cancer is likely safe and may offer improved pain and ROM compared to forgoing surgery without necessarily increasing the risk for postoperative complication.

Imageless Computer Navigation Reduces 5-Year All-Cause Revision Rates After Primary Total Knee Arthroplasty

BACKGROUND

The use of surgical navigation has been shown to reduce revision rates after total knee arthroplasty (TKA) in patients <65 years of age. It is unknown if this benefit extends to older patients. We hypothesized that the use of surgical navigation would reduce rates of all-cause revision in patients of all ages.

METHODS

In this cohort study, we queried the Truven MarketScan all-payer database to identify patients who underwent TKA from 2007 to 2015. Current Procedural Terminology codes were used to create 2 groups based on whether intraoperative navigation was used. Demographics, comorbidities, complications, and revision rates were determined. International Classification of Diseases codes were used to determine reasons for revision.

RESULTS

The conventional TKA cohort included 312,173 patients. The navigation cohort included 20,881 patients. There were not any clinically significant differences in demographics between the cohorts. All-cause revision rates were lower in the navigation cohort at 1 year (0.4% vs 0.5%, P = .04), 2 years (0.7% vs 0.9%, P = .003), and 5 years (0.9% vs 1.3%, P < .001) of follow-up. Revisions for mechanical loosening were more common in the conventional cohort (30.8% vs 21.9%, P = .009). Rates of revision for other causes, including infection, did not differ between groups, with the numbers available.

CONCLUSION

The use of surgical navigation yielded a 30.7% reduction in the all-cause revision rate at 5-year follow-up compared to conventional TKA. This benefit increased as follow-up duration increased. Increased usage of this inexpensive technology, from the current 6.3% in this US cohort, may reduce healthcare costs.

Arthroscopic Rotator Cuff Repair Results in Lower Two-Year Reoperation Rates Compared With Open Rotator Cuff Repair in a Large Cross-sectional Cohort

PURPOSE

To use a large, contemporary database to perform a cross-sectional analysis of current practice trends in rotator cuff repair (RCR) for the treatment of full-thickness rotator cuff tear (RCT) and determine outcomes of arthroscopic and open RCR, including hospital readmissions and 2-year reoperation rates with accurate laterality tracking using International Classification of Diseases, Tenth Revision (ICD-10) codes.

METHODS

The PearlDiver Mariner dataset was used to query patients with full-thickness RCTs from 2010 to 2017. Propensity-score matching was performed to account for differences in age and comorbidities and allow for comparison between those undergoing open RCR and arthroscopic RCR. Subsequent procedures were tracked using ICD-10 codes to identify ipsilateral surgery within 2 years of index surgery. Hospital and emergency department admission within 30 days of surgery were investigated.

RESULTS

Of 534,076 patients diagnosed with full-thickness RCT, 37% underwent RCR; 73% of which were arthroscopic. From 2010 to 2017, arthroscopic RCRs increased from 65% to 80%, whereas open RCRs decreased from 35% to 20% (P < .0001). Younger patients underwent arthroscopic RCR more frequently, and patients who underwent open RCR had greater rates of 30-day emergency department (7.0%) and hospital readmission (2.0%) compared with arthroscopic RCR (6.3%, 1.0%, respectively) (P < .0001). For 24,392 patients with ICD-10 coding and 2-year follow-up, 10.4% of patients required reoperation, with the most common procedure being revision RCR, and 1.3% required conversion to arthroplasty. Open RCRs were more likely to require subsequent surgery (11.3%) compared with arthroscopic RCR (9.5%) (P < .0001). Patients aged 50 to 59 had the greatest rate of reoperation (14.0%), but no patients younger than age 40 years required reoperation, and no patients younger than age 50 years required conversion to arthroplasty.

CONCLUSIONS

The frequency of arthroscopic RCR has continued to increase compared to open RCR. In this large cross-sectional analysis, arthroscopic RCR demonstrated lower 2-year reoperation rates and 30-day readmission rates compared to open RCR.

The rate and reporting of fracture after biceps tenodesis: A systematic review

BACKGROUND

The purpose of this systematic review was to (1) define the cumulative humerus fracture rate after BT and (2) compare how often fracture rate was reported compared to other complications.

METHODS

A systematic review was performed using the PRISMA guidelines.

RESULTS

39 studies reported complications and 30 reported no complications. Of the 39 studies that reported complications, 5 studies reported fracture after BT (n = 669, cumulative incidence of 0.53%). The overall non-fracture complication rate was 12.9%.

DISCUSSION

Due to the relatively high incidence of fracture, surgeons should ensure that this complication is disclosed to patients undergoing BT.

Influential factors of subacromial impingement syndrome after hook plate fixation for acromioclavicular joint dislocation: A retrospective study

Subacromial impingement syndrome (SIS) after hook plate fixation for acromioclavicular joint (AC) dislocation was the most common complication. However, the researches on its' influential factors were rare. The purpose of this study was to identify the risk factors by analyzing the influencing factors of postoperative SIS and minimize the incidence of SIS in clinical surgery.We retrospectively analyzed the prospectively collected data from 330 consecutive patients with AC joint dislocation between August 2014 and August 2017 at our institute. The SIS was presented as the dependent variable at the last follow-up when the internal fixation was removed. The independent variables included age, gender, body-mass index (BMI), smoking status, alcohol consumption, type of injury, Rockwood Classification, site of injury, operation time, injury-to-surgery, the distance between the hook body and the acromion (DBA), the depth of hook tip (DHT), the distance between the hook plate and the humeral head (DHH), the distance between the acromion and the humeral head (DAH), the hook plate angle (AHP) and acromial shape. Logistic regression analysis was performed to identify independent influential factors of SIS.A total of 312 cases were included and 18 cases were lost. The follow-up rate was 94.5%. In without SIS group, there were 225 cases (123 males and 102 females). In with SIS group, a total of 87 cases were included (56 males and 31 females). The incidence of SIS was 27.8%. DHT (OR = 9.385, 95% CI = 4.883 to 18.040, P < .001) and DBA (OR = 2.444, 95% CI = 1.591 to 3.755, P < .001) were the significant independent risk factor for SIS of AC dislocation treat with hook plate. DAH (OR = 0.597, 95% CI = 0.396 to 0.900, P = .014) and acromial shape with flat and straight (OR = 0.325, 95% CI = 0.135 to 0.785, P = .012) were also independent factors of SIS, but they were all protective.The SIS had a high incidence in fixation of clavicular hook plate for AC dislocation. DHT and DBA were two independent risk factors, DAH and acromial shape with flat and straight were two independent protective factors for SIS. In clinical surgery, we should avoid risk factors to reduce the incidence of SIS.
