Purpose: The purpose of this historical prospective study was to compare the pre- and post-operative Quality of Life (QOL) outcomes 12 months post-operatively between Articular Tears (AT) and Bursal Tears (BT) of patients with partial thickness tear of the rotator cuff. Methods: Data of 93 consecutive patients diagnosed with Partial Thickness Tear (PTT) who had undergone decompression, acromiploasty, or repair were used to compare outcome between patients with Articular Tears and Bursal Tears. The QOL outcome measures included one disease specific outcome measure, the Western Ontario Rotator Cuff Index (WORC) and two shoulder specific measures, the American Shoulder & Elbow Surgeons standardized shoulder assessment form (ASES) and the Constant-Murley score. A statistical paired t-test (pre vs. 12 months) and an independent t-test analysis (Articular vs. Bursal) were conducted to examine the impact of the tear site. Results: Forty-four Articular and 49 Bursal tears (48 females and 45 males) were included in the analysis. The mean age was 55.5 (SD: 13) and 53.3 (SD: 12) for the AT and BT groups respectively. There was no statistically significant difference between two groups in pre-operative QOL outcome scores. Both groups showed significant improvement in the above outcomes (p< 0.0001) one year following surgery. However, the AT group was significantly less improved than the BT group in the ASES scores (p=0.005), and Constant-Murley scores (p=0.035). The WORC was not sensitive in differentiating between the two groups (p=0.11). Conclusion: The intent of this study was to compare the pre-operative and rate of improvement in two groups of patients suffering from different site of rotator cuff pathology. The results indicate that the quality of life improves significantly regardless of the tear site. The pattern of recovery however is different indicating that patients with Bursal tear show a higher degree of improvement in their functional measures, possibly due to reduced mechanical compression on rotator cuff

The purpose of this historical prospective study was to compare the pre and post-operative Quality of Life (QOL) outcomes twelve months post-operatively in patients with partial thickness rotator cuff tears. Data of ninety-three consecutive patients diagnosed with Partial Thickness Tear (PTT) who had undergone decompression, acromioplasty, or repair were used to compare the outcome between patients with Articular Tears (AT) and Bursal Tears (BT). The QOL outcome measures included one disease specific outcome measure, the Western Ontario Rotator Cuff Index (WORC) and two shoulder specific measures, the American Shoulder & Elbow Surgeons standardised shoulder assessment form (ASES) and the Constant-Murley score. A statistical paired t-test (pre vs. twelve months) and an independent t-test analysis (Articular vs. Bursal) were conducted to examine the impact of the tear site. Forty-four Articular and forty-nine Bursal tears (forty-eight females and forty-five males) were included in the analysis. The mean age was 55.5 (SD: 13) and 53.3 (SD: 12) for the AT and BT groups respectively. There was no statistically significant difference between the two groups in pre-operative QOL outcome scores. Both groups showed significant improvement in the above outcomes (p< 0.0001) one year following surgery. However, the AT group was significantly less improved than the BT group in the post-op ASES scores (p=0.04), Constant-Murley scores (p=0.006) and WORC (p=0.01). The intent of this study was to compare the pre and post operative scores and rate of improvement in two groups of patients suffering from rotator cuff pathology at different sites. The results indicate that the quality of life improves significantly regardless of the tear site. The pattern of recovery however is different indicating that patients with Bursal tears show a higher degree of improvement in their functional measures. The findings suggest that two types of tears are different in their etiology and pathomechanics

Poor shoulder function may complicate the non-operative treatment of a humeral diaphyseal fracture. This has often been regarded as an unavoidable consequence of the relative immobility of the shoulder during brace treatment. Tears of the rotator cuff have not previously been recognised as an underlying cause of persistent shoulder pain and stiffness in this situation. In this report, we identified six patients, from a consecutive series of 294 patients with humeral fractures treated in our Institution over a five-year period, who were found to have symptomatic rotator cuff tears following non-operative treatment of their humeral diaphyseal fracture. All had normal pre-injury upper limb function, but had persistent pain and loss of active shoulder movement after their fracture had united. Large, retracted cuff tears, affecting the cuff muscles attached to the greater tuberosity, were identified pre-operatively from imaging of the rotator cuff and intra-operatively at open surgery. Surgical reconstruction of the cuff was carried out in all cases and yielded satisfactory return of shoulder function, on assessment at least eighteen months after injury

Hip abductor tears(AT) have long been under-recognized, under-reported and under-treated. There is a paucity of data on the prevalence, morphology and associated factors. Patients with “rotator cuff tears of the hip” that are recognized and repaired during total hip arthroplasty(THA) report comparable outcomes to patients with intact abductor tendons at THA.

The study was a retrospective review of 997 primary THA done by a single surgeon from 2012–2022. Incidental findings of AT identified during the anterolateral approach to the hip were documented with patient name, gender, age and diagnosis. The extent and size of the tears of the Gluteus medius and Minimus were recorded. Xrays and MRI's were collected for the 140 patients who had AT and matched 1:1 with respect to age and gender against 140 patients that had documented good muscle quality and integrity. Radiographic measurements (Neck shaft angle, inter-teardrop distance, Pelvis width, trochanteric width and irregularities, bodyweight moment arm and abductor moment arm) were compared between the 2 groups in an effort to determine if any radiographic feature would predict AT.

The prevalence of AT were 14%. Females had statistically more tears than males(18vs10%), while patients over the age of 70y had statistically more tears overall(19,7vs10,4%), but also more Gluteus Medius tears specifically(13,9vs5,3%). Radiographic measurements did not statistically differ between the tear and control group, except for the presence of trochanteric irregularities. MRI's showed that 50% of AT were missed and subsequently identified during surgery.

Abductor tears are still underrecognized and undertreated during THA which can results in inferior outcomes. The surgeon should have an high index of suspicion in elderly females with trochanteric irregularities and although an MRI for every patient won't be feasible, one should always be prepared and equipped to repair the abductor tendons during THA.

Meniscal tears commonly co-occur with ACL tears, and many studies address their side, pattern, and distribution. Few studies assess the patient's short-term functional outcome concerning tear radial and circumferential distribution based on the Cooper et al. classification. Meniscal tears require primary adequate treatment to restore knee function. Our hypothesis is to preserve the meniscal rim as much as possible to maintain the load-bearing capacity of the menisci after meniscectomy.

The purpose of this study is to document the location and type of meniscal tears that accompany anterior cruciate ligament (ACL) tears and their effect on patient functional outcomes following arthroscopic ACL reconstruction and meniscectomy.

This prospective cross-sectional observational study was conducted at AL-BASRA Teaching Hospital in Iraq between July 2018 and January 2020 among patients with combined ipsilateral ACL injury and meniscal tears. A total of 28 active young male patients, aged 18 to 42 years, were included. All patients were subjected to our questionnaire, full history, systemic and regional examination, laboratory investigations, imaging studies, preoperative rehabilitation, and were followed by Lysholm score 6 months postoperatively.

All 28 patients were males, with a mean age of 27 ± 0.14 years. The right knee was the most commonly affected in 20/28 patients (71.4%). The medial meniscus was most commonly injured in 11 patients, 7 patients had lateral meniscal tears, and 10 patients had tears in both menisci. The most common tear pattern of the medial meniscus was a bucket handle tear (36.4%), while longitudinal tears were the most frequent in the lateral meniscus (71.4%) (P-value = 0.04). The most common radial tear location was zone E-F (5/28, 17.8%), and the most common circumferential zone affected was the middle and inner third, reported in 50% of tears. Good and excellent outcomes using the Lysholm score after 6 months were obtained in 42.9% and 17.9% of patients, respectively. Better functional scores were associated with lateral meniscal tears, bucket handle tears, tears extending to a more peripheral vascular area, and if no more than one-third of the meniscus was resected (P-value = 0.002). Less favourable outcomes were reported in smokers, posterior horn tears, and when surgery was delayed more than 1 year (P-value = 0.03).

We conclude that there is a negative correlation between the amount of meniscus resected and functional outcome. Delayed ACL reconstruction increases the risk of bimeniscal tears. Bucket handle tears are the most common tears, mostly in the medial meniscus, while longitudinal tears are most common in the lateral meniscus. We recommend performing early ACL reconstruction within 12 months to reduce the risk of bimeniscal injuries.

Magnetic resonance imaging (MRI) is the gold standard for the diagnosis of the pathologies affecting the glenohumeral joint and the rotator cuff diseases. MRI allows to highlight anatomic discontinuities of both muscles and tendons. However, MRI diagnostic accuracy has not proven to be highly sensitive in distinguishing between a partial-thickness tear and a full-thickness rotator cuff tear. The purpose of this study was to determine if MRI under axial traction can be helpful in increasing MRI sensitivity to identify partial-thickness rotator cuff tears.

The study included 10 patients (4 males and 6 females) who had clinical examination and MRI suggesting a partial-thickness rotator cuff tear. They were candidates for shoulder arthroscopy because of persistent symptoms after at least three months of conservative treatment. The patients underwent a new MRI (under axial traction: MRI-AT) with a 4-kg weight applied to the affected arm. Then the patients underwent arthroscopy to confirm the diagnosis. Patients with a suspected full-thickness rotator cuff tear were excluded from the study.

Patients’ average age was 52.4 years, and the dominant side was affected in 77.7% of the cases. Preoperative Constant-Murley Score was 57. MRI-AT showed that 3 patients were affected by a complete tear of the rotator cuff, 3 patients by a partial-thickness rotator cuff tear and 4 patients had no lesion. The analysis of data showed that: under axial traction the subacromial space increased by 0,2 mm (P value = 0,001075), the superior glenohumeral space decreased by 2.4 mm (P value = 0,07414), the inferior glenohumeral space increased by 0.3 mm (P value = 0,02942), the acromial angle decreased by 1.9° (P value = 0,0002104) and the acromion-glenohumeral angle decreased by 0.3° (P-value = 0,01974). Two experienced evaluators analyzed previous standard MRI and MRI-AT scans in a double-blinded fashion, with inter-rater evaluation of all the images and measures. Intraclass correlation coefficient (ICC) has been utilized to assess the reliability of the measures performed by different operators. ICC always resulted in more than 0.7, showing a high concordance among values in the same group. A comparative evaluation between standard MRI and MRI-AT has been conducted to highlight possible discrepancies and this has been compared to intraoperative findings. Concordance of the values was 89% between standard MRI and MRI-AT and 100% between MRI under axial traction and intraoperative findings.

This study showed a high correlation between the diagnosis achieved with MRI-AT and the intraoperative arthroscopic findings. The use of MRI-AT in clinical practice may improve the diagnostic sensitivity of this method to detect a partial-thickness rotator cuff tear.

Rotator cuff tears are common, with failure rates of up to 94% for large and massive tears¹. For such tears, reattachment of the musculotendinous unit back to bone is problematic, and any possible tendon-bone repair heals through scar tissue rather than the specially adapted native enthesis. We aim to develop and characterise a novel soft-hard tissue connector device, specific to repairing/bridging the tendon-bone injury in significant rotator cuff tears, employing decellularised animal bone partially demineralised at one end for soft tissue continuation.

Optimisation samples of 15×10×5mm³, trialled as separate cancellous and cortical bone samples, were cut from porcine femoral condyles and shafts, respectively. Samples underwent 1-week progressive stepwise decellularisation and a partial demineralisation process of half wax embedding and acid bathing. Characterisations were performed histologically for the presence/absence of cellular staining in both peripheral and central tissue areas (n=3 for each cortical/cancellous, test/PBS control and peripheral/central group), and with BioDent reference point indentation (RPI) for pre- and post-processing mechanical properties.

Histology revealed absent cellular staining in peripheral and central cancellous samples, whilst reduced in cortical samples compared to controls. Cancellous samples decreased in wet mass after decellularisation by 45.3% (p<0.001). RPI measurements associated with toughness (total indentation depth, indentation depth increase) and elasticity (1st cycle unloading slope) showed no consistent changes after decellularisation. X-rays confirmed half wax embedding provided predictable control of the mineralised-demineralised interface position.

Initial optimisation trials show proof-of-concept of a soft-hard hybrid scaffold as an immune compatible xenograft for irreparable rotator cuff tears. Decellularisation did not appreciably affect mechanical properties, and further biological, structural and chemical characterisations are underway to assess validity before in vivo animal trials and potential clinical translation.

Data were collected on patients undergoing subacromial decompression (SAD) in our routine practice from 1998 to 2004. All patients had clinical signs of subacromial pain and had failed conservative treatment. Tears were not repaired. Data on age, gender, arm dominance and presence of cuff tear at operation were recorded. At six months post-operatively, patients were assessed with the Constant Score (CS). Data were analysed using multiple linear regression. Data on 427 patients were collected, 168 having rotator cuff tears. The mean age was 55.41 years (SD 12.00). There were 233 women and 191 men. There were no significant gender differences between the two groups (x2=2.34, df=1, p=0.13). The group with cuff tears were significantly older by 10.24 years (p< 0.001, 8.10 to 12.38). Power of the study was 90% at the 5% significance level. Multiple linear regression showed that gender, age and presence of a cuff tear all had a significant effect on the CS. Gender B = 5.52 (1.99 to 9.06) p = 0.002 Age B = −0.31 (−0.48 to −0.15) p < 0.001 Cuff tear B = −5.51 (−9.48 to −1.55) p = 0.007 Hand dominance and the side operated upon had no significant effect. We found that in patients with symptomatic shoulders, who had failed conservative treatment and undergone an SAD, the CS at six months follow up was lower in those who had a cuff tear. There was increased tear prevalence in slightly older patients, and these scored on average 5.5 (1.5 to 9.5) points less than expected on the CS, p = 0.007, after allowing for age and gender. We believe that the surgeon should discuss with the patient whether a 5.5 points lower score is enough of a difference to warrant a formal rotator cuff repair rather than debridement and SAD alone, and a joint decision should be made

16 to 34% of the population suffer from shoulder pain, the most common cause being rotator cuff tears. NICE guidance recommends using ultrasound scan (USS) or MRI to assess these patients, but does not specify which is preferable. This study assesses the accuracy of USS and MRI in rotator cuff tears in a DGH, to establish the most appropriate imaging modality.

Patients who had at least two of shoulder ultrasound, MRI or arthroscopy within a seven month period (n=55) were included in this retrospective study. Sensitivity, Specificity, Positive Predictive Value (PPV) and Negative Predictive Value (NPV) were calculated using arthroscopy as the true result, and kappa coefficients calculated for each pairing.

59 comparisons were made in total. Sensitivity for MRI in full supraspinatus tears was 0.83, and for USS 0.75. Specificity for MRI in these tears was 0.75, and for USS 0.83. Values were much lower in other tears, which occurred less frequently. USS and MRI completely agreed with each other 61.3% of the time. Both modalities were only completely accurate 50% of the time. Kappa coefficient between arthroscopy and MRI for supraspinatus tears was 0.658, and for USS was 0.615.

There was no statistical difference between MRI and USS sensitivity or specificity (p=1), suggesting that one modality cannot be recommended over the other for full supraspinatus tears. They also do not tend to corroborate one another, suggesting that there is no benefit from doing both scans. Further research is needed to see how both modalities can be improved to increase their accuracy.

Introduction. Superior Labral Anterior Posterior Tears are being treated surgically in increasing numbers. Stiffness is the most common complication. We reviewed 115 cases of SLAP repairs to try and identify preoperative risk factors if any for stiffness. Methods. Retrospective cohort study of 115 patients who underwent SLAP repair. All patients failed attempts at conservative therapy including NSAIDS, Physical Therapy and cortisone injections. Results. Age ranged from 16–71 years, with an average age of 46. Male 84, Female 31. patient charts and operative notes were examined from 2004–2009. We used an average of 1.64 anchors per case; we performed arthroscopic Mumford on 15 patients, subscap repair (4), 19 cases with concomitant SLAP repair and Arthroscopic rotator cuff repair Other procedures included Biceps tenotomy and tenodesis, chondroplasty, Microfracture, removal of loose bodies, synovectomy and lysis of adhesions. Twelve patients underwent revision surgery(10%) We had 5 cases of stiffness which required lysis of adhesions and synovectomy, 4 cases had previous SLAP and concomitant rotator cuff repair done at the index surgery, 4 cases had arthrosis noted at index surgery and underwent chondroplasty and 2 of them underwent micro fracture. During the revision surgery 4 had also a concomitant cuff tear (new) which required repair Average time from index surgery to revision was 11 months, the patients who developed adhesive Capsulitis and stiffness the average age was 56 years. We had 2 titanium metal anchors pull out and present as loose bodies with one of the anchor causing chondral damage, we stopped using metal anchors and we have not had this problem recur since.5 cases had Mumford procedure done during the revision surgery.5 cases needed repeat SLAP repairs and by increasing use of biceps tenotomy this incidence should decrease. Conclusions. Our large retrospective case series shows an acceptable complication rate. Stiffness (5%) is still the most common complication especially in patients older than 50, withpreexisting Glenohumeral arthritis and concomitant rotator cuff tears. Hopefully our early aggressive mobilization will decrease this incidence

Objective: Various tear types and patterns of meniscus injuries have been described. We record meniscus tear type and pattern in a standard manner for every knee arthroscopy in our database of more than 17,000 knee surgeries. We determined if meniscus tear type and pattern correlate with function and activity levels at least two years after partial meniscectomy. Methods: Two hundred six (206) patients underwent partial medial meniscectomy and 117 underwent partial lateral meniscectomy by a single surgeon (average age=49 years; range, 18 to 80). At index surgery, the type and pattern of meniscus tear was recorded. Tears were designated as bucket handle/vertical longitudinal (BV), flap/radial (FR), or complex (CH) which includes horizontal cleavage tears. Patients not in neutral or near-neutral alignment and those undergoing concurrent procedures for microfracture or ACL reconstruction were excluded. Patients were followed for a minimum of two years (average=4.6 yrs) after partial meniscectomy. Patients completed questionnaires including Lysholm and Tegner scores to assess function and activity. Results: For the medial meniscus, there was significant correlation between tear type and patient age. The BV lesion group (n=35) was significantly younger (41 years) than the FR (n=65) (50 years) and CH (n=193) (53 years) groups (p=0.01). The BV group had significantly higher Lysholm (89) scores versus FR (80) and CH (77) (p=0.04). The BV group also had higher Tegner activity levels (5.8) than FR (4.6) and CH (4.5) (p=0.04). For lateral meniscus, the BV (n=15) (40 years) and FR (n=37) (48 years) groups were significantly younger than the CH group (n=45) (56 years); p=0.03. FR patients had higher Lysholm and Tegner scores, but not significantly different. Twenty-five percent (25%) of BV medial meniscus tears required further surgery while less than 15% of other types of medial or lateral tears required further surgery. Average time to second surgery for all patients was 2.4 years, with medial being 2.6 years and lateral being 1.5 years. Conclusions: In this series, BV medial meniscus tears had better function and activity levels at least two years post-meniscectomy, perhaps due to younger age. This group also required more reoperations during the first two years after index meniscectomy than any other group, perhaps as a result of higher activity levels. Overall, partial lateral meniscectomy patients required reoperation sooner than medial meniscectomies. Tear type did not significantly influence outcomes after lateral meniscectomy. Therefore, meniscus tear type and pattern correlated with function and activity levels for medial but not lateral > 2 years after partial meniscectomy

Abstract

Abstract

Partial thickness abductor tendon tears are a significant source of recalcitrant laterally based hip pain. For those that fail conservative treatment, the results of endoscopic repair are highly successful with minimal morbidity. The principal burden is the protracted rehabilitation that is necessary as part of the recovery process. There is a wide gap between failed conservative treatment and successful surgical repair. It is hypothesized that a non-repair surgical strategy, such as a bioinducitve patch, could significantly reduce the burden associated recovery from a formal repair. Thus, the purpose of this study is to report the preliminary results of this treatment strategy.

Symptomatic partial thickness abductor tendon tears are treated conservatively, including activity modification, supervised physical therapy and ultrasound guided corticosteroid injections. Beginning in January 2022, patients undergoing hip arthroscopy for intraarticular pathology who also had persistently symptomatic partial thickness abductor tendon tears, were treated with adjunct placement of a bioinducitve (Regeneten) patch over the tendon lesion from the peritrochanteric space. The postop rehab protocol is dictated by the intraarticular procedure performed. All patients are prospectively assessed with a modified Harris Hip Score (mHHS) and iHOT and the tendon healing response examined by ultrasound.

Early outcomes will be presented on nine consecutive cases.

Conclusions - Will be summarized based on the preliminary outcomes to be reported.

A larger radial tuberosity, and therefore a smaller radioulnar space, may cause mechanical impingement of the DBT predisposing to tear. We sought to investigate anatomic factors associated with partial DBT tears by retrospectively reviewing 3-T MRI scans of elbows with partial DBT tears and a normal elbow comparison group

3-T MRI scans of elbows with partial DBT tears and elbows with no known pathology were reviewed retrospectively by two independent observers. Basic demographic data were collected and measurements of radial tuberosity length, radial tuberosity thickness, radio-ulnar space, and radial tuberosity-ulnar space were made using simultaneous tracker lines and a standardised technique. The presence or absence of enthesophytes and the presence of a single or double DBT were noted.

26 3-T MRI scans of 26 elbows with partial DBT tears and 30 3-T MRI scans of 30 elbows without pathology were included. Basic demographic data was comparable between the two groups. The tear group showed statistically significant larger mean measurements for radial tuberosity length (24.3mm vs 21.3mm, p=0.002), and radial tuberosity thickness (5.5mm vs 3.7mm, p=<0.0001. The tear group also showed statistically significant smaller measurements for radio-ulnar space (8.2mm vs 10.0mm, p=0.010), and radial tuberosity-ulnar space (7.2mm vs 9.1mm, p=0.013). There was a statistically significant positive correlation between partial DBT tears and presence of enthesophytes (p=0.007) as well as between partial DBT tears and having two discrete DBTs rather than a single or interdigitating tendon (p=<0.0001).

Larger radial tuberosities, and smaller radio-ulnar and radial tuberosity-ulnar spaces are associated with partial DBT tears. This may be due to chronic impingement, tendon delamination and consequent weakness which ultimately leads to tears. Enthesophytes may be associated with tears for the same reason. Having two discrete DBTs that do not interdigitate prior to insertion is also associated with partial tears.

Aims

We studied the outcomes following arthroscopic primary repair of bucket handle meniscus tears to determine the incidence of re-tears and the functional outcomes of these patients.

The function of the upper extremity is highly dependent on correlated motion of the shoulder. The shoulder can be affected by several diseases. The most common are: rotator cuff tear (RCT), shoulder instability, shoulder osteoarthritis and fractures. Rotator cuff disease is a common disorder. It has a high prevalence rate, causing high direct and indirect costs. The appropriate treatment for RCT is debated. The American Academy Orthopaedic Surgeons guidelines state that surgical repair is an option for patients with chronic, symptomatic full-thickness RCT, but the quality of evidence is unconvincing. Thus, the AAOS recommendations are inconclusive. We are performing a randomized controlled trial to compare surgical and conservative treatment of RCT, in term of functional outcomes, rotator cuff integrity, muscle atrophy and fatty degeneration. Shoulder instability occurs when the head of the upper arm bone is forced out of the shoulder socket. Shoulder instabilities have been classified according to the etiology, the direction of instability, or on combinations thereof. The Thomas and Matsen classification, which is currently the most commonly utilized classification, divides shoulder instability events into the traumatic, unidirectional, Bankart lesion, and surgery (TUBS) and the atraumatic, multidirectional, bilateral, rehabilitation, and capsular shift (AMBRI) categories. The acquired instability overstress surgery (AIOS) category was then added. Surgical procedures for shoulder instability includes arthroscopic capsuloplasty, remplissage, bone block procedure or Latarjet procedure. Reverse total shoulder arthroplasty (RTSA) represents a good solution for the management of patients with osteoarthritis or fracture of the proximal humerus, with associated severe osteoporosis and RC dysfunction.

Massive posterosuperior cuff tears (mRCT) retracted to the glenoid are surgically challenging and often associated with high retear rates. Primary repair is a less-favourable option and other salvage procedures such as SCR and tendon transfers are used. This study presents clinical and radiological outcomes of muscle advancement technique for repair of mRCT.

Sixty-one patients (mean age 57±6, 77% males and 23% females) (66 shoulders) underwent all-arthroscopic rotator cuff repair that included supraspinatus and infraspinatus subperiosteal dissection off scapular bony fossae, lateral advancement of tendon laminae, and tension-free double-layer Lasso Loop repair to footprint.

Pre-and post-operative range of motion (ROM), cuff strength, VAS, Constant, ASES, and UCLA scores were assessed. Radiologic assessment included modified Patte and Goutallier classifications. All patients had MRI at 6 months to evaluate healing and integrity of repair was assessed using Sugaya classification with Sugaya 4 and 5 considered retears.

Advanced fatty degeneration (Goutallier 3-4) was present in 44% and 20% of supraspinatus and infraspinatus. Tendon retraction was to the level of or medial to glenoid in 22%, and just lateral in 66%. 50.8% mRCT extended to teres minor. Subscapularis was partially torn (Lafosse 1-3) in 46% and completely torn (Lafosse 4-5) in 20%.

At mean follow-up (52.4 weeks), a significant increase in ROM, Relative Cuff Strength (from 57% to 90% compared to contralateral side), VAS (from 4 ±2.5 to 1±1.7), Constant (50±17.8 to 74 ±13.0), ASES (52 ±17.5 to 87 ±14.9), and UCLA (16± 4.9 to 30 ±4.9) scores were noted. There were six retears (10%), one failure due to P. acnes infection. 93% returned to pre-injury work and 89% of cases returned to pre-injury sport. Satisfaction rate was 96%.

Muscle advancement technique for mRCT is a viable option with low retear rates, restoration of ROM, strength, and excellent functional outcomes.

Abstract

We performed this systematic overview on the overlapping meta-analyses that analyzed autologous platelet-rich plasma (PRP) as an adjuvant in the repair of rotator cuff tears and identify the studies which provide the current best evidence on this subject and generate recommendations for the same.

We conducted independent and duplicate electronic database searches in PubMed, Web of Science, Scopus, Embase, Cochrane Database of Systematic Reviews, and the Database of Abstracts of Reviews of Effects on September 8, 2021, to identify meta-analyses that analyzed the efficacy of PRP as an adjuvant in the repair of rotator cuff tears. Methodological quality assessment was made using Oxford Levels of Evidence, AMSTAR scoring, and AMSTAR 2 grades and used the Jadad decision algorithm to generate recommendations.

20 meta-analyses fulfilling the eligibility criteria were included. The AMSTAR scores of the included studies varied from 6–10 (mean:7.9). All the included studies had critically low reliability in their summary of results due to their methodological flaws according to AMSTAR 2 grades. The initial size of the tear and type of repair performed do not seem to affect the benefit of PRPs. Among the different preparations used, leucocyte poor (LP)-PRP possibly offers the greatest benefit as a biological augment in these situations.

Based on this systematic overview, we give a Level II recommendation that intra-operative use of PRPs at the bone-tendon interface can augment the healing rate, reduce re-tears, enhance the functional outcomes and mitigate pain in patients undergoing arthroscopic rotator cuff repair.
