Subscapularis Management in Anatomic Total Shoulder Arthroplasty A Review.

Surgical management of the subscapularis tendon is critical to a successful outcome following anatomic total shoulder arthroplasty. However, the optimal surgical technique for adequate exposure of the glenohumeral joint while mini-mizing complications resulting from subscapularis tendon dysfunction continues to be controversial. Common surgical techniques for the management of the subscapularis tendon include tenotomy, peeling, sparing, and lesser tuberosity oste-otomy. Despite a number of published studies comparing these techniques, no consensus has been reached regarding optimal management. This article reviews the extensive literature on the biomechanical, radiologic, and clinical outcomes of each technique, including recently published comparison studies.

Comparison of decrease in elbow flexion strength in patients after tenotomy and tenodesis of the long head of the biceps brachii.

NTRODUCTION: The last two decades have been leading to the development of several types of surgical techniques and procedures to manage the LHB lesions. This paper analyses and compares the difference in muscle strength pre- and post-operatively in two most commonly used surgical procedures - LHB tenotomy and tenodesis. METHOD: The study includes 68 patients who underwent surgery between 2016 and 2020. The patients who had met the prospective study inclusion criteria were divided into two groups based on type of surgery they had undergone (LHB tenotomy or tenodesis); each group consisted of 34. The muscle strength during elbow flexion was measured preoperatively and postoperatively using the Commander Echo Console ultrasound muscle testing device. All patients enrolled in the study had been assessed for elbow flexion strength preoperatively. The muscle strength was measured preoperatively and then 3 years postoperatively (12 to 60 months) on average. CONCLUSION: The study confirmed that the patients who had undergone LHB tenodesis show a significantly lower decrease in elbow flexion strength and a significantly lower incidence of "Popeye" deformity than the patients after LHB tenotomy. Moreover, in the tenodesis group, it was possible to initiate rehabilitation earlier. The incidence of postoperative complications was almost identical in both groups of patients (Tab. 10, Fig. 6, Ref. 40).

Satisfactory mid-term clinical outcomes of endoscopic tenotomy for iliopsoas tendinopathy following total hip arthroplasty.

PURPOSE: To report 5-year outcomes of endoscopic iliopsoas tenotomy in patients with iliopsoas tendinopathy following total hip arthroplasty (THA) and determine whether clinical scores are associated with cup position. METHODS: Patients who underwent endoscopic iliopsoas tenotomy for iliopsoas tendinopathy following THA (2014-2017) were contacted. Indications for endoscopic iliopsoas tenotomy after THA were groin pain during active hip flexion, exclusion of other causes of groin pain, and no pain relief after 6 months of conservative treatment. Pretenotomy cup inclination and anteversion were measured on radiographs; axial and sagittal cup overhang were measured on computed tomography (CT) scans. Oxford hip score (OHS), modified Harris hip score (mHHS), and groin pain were assessed. RESULTS: The initial cohort comprised 16 men (17 hips) and 31 women (32 hips), aged 60.7 ± 10.6 years. Cup inclination and anteversion were, respectively, 46.2 ± 6.2° and 14.6 ± 8.4°, while axial and sagittal cup overhang were, respectively, 4.4 ± 4.0 mm and 6.9 ± 4.5 mm. At ≥5 years follow-up, four hips underwent cup and stem revision, two underwent isolated cup revision and one underwent secondary iliopsoas tenotomy. OHS improved by 23 ± 10 and mHHS improved by 31 ± 16. Posttenotomy groin pain was slight in 20.0%, mild in 17.5% and moderate in 12.5%. Regression analyses revealed that net change in mHHS decreased with sagittal cup overhang (ß = -3.1; 95% confidence interval [CI] = -4.6 to -1.7; p < 0.001), but that there were no associations between cup position and net change in OHS. CONCLUSIONS: Endoscopic iliopsoas tenotomy provides good mid-term clinical outcomes in patients with iliopsoas tendinopathy following THA. Furthermore, improvements in mHHS were found to decrease with increasing sagittal cup overhang, in cases for which adequate preoperative imaging was available. LEVEL OF EVIDENCE: Level IV.

Roles of Plasminogen Activator Inhibitor-1 in Heterotopic Ossification Induced by Achilles Tenotomy in Thermal Injured Mice.

Heterotopic ossification (HO) is the process by which ectopic bone forms at an extraskeletal site. Inflammatory conditions induce plasminogen activator inhibitor 1 (PAI-1), an inhibitor of fibrinolysis, which regulates osteogenesis. In the present study, we investigated the roles of PAI-1 in the pathophysiology of HO induced by trauma/burn treatment using PAI-1-deficient mice. PAI-1 deficiency significantly promoted HO and increased the number of alkaline phosphatase (ALP)-positive cells in Achilles tendons after trauma/burn treatment. The mRNA levels of inflammation markers were elevated in Achilles tendons of both wild-type and PAI-1-deficient mice after trauma/burn treatment and PAI-1 mRNA levels were elevated in Achilles tendons of wild-type mice. PAI-1 deficiency significantly up-regulated the expression of Runx2, Osterix, and type 1 collagen in Achilles tendons 9 weeks after trauma/burn treatment in mice. In in vitro experiments, PAI-1 deficiency significantly increased ALP activity and mineralization in mouse osteoblasts. Moreover, PAI-1 deficiency significantly increased ALP activity and up-regulated osteocalcin expression during osteoblastic differentiation from mouse adipose-tissue-derived stem cells, but suppressed the chondrogenic differentiation of these cells. In conclusion, the present study showed that PAI-1 deficiency promoted HO in Achilles tendons after trauma/burn treatment partly by enhancing osteoblast differentiation and ALP activity in mice. Endogenous PAI-1 may play protective roles against HO after injury and inflammation.

Can the Achilles tendon regenerate completely following percutaneous tenotomy in older children with clubfoot?

PURPOSE: The aims of the study were to document the outcomes of percutaneous Achilles tenotomy (pAT) performed in older children with clubfoot, by assessing the clinical, functional and ultrasonographic evidence of Achilles tendon regeneration. METHODS: A retrospective case series of older children with clubfoot treated between August 2011 and July 2020 was studied. Clinical assessment of ankle range of motion and calf strength, functional assessment of triceps surae muscle endurance by single leg heel-rise test, and ultrasonographic assessment of Achilles tendon echotexture and dimensions to assess tendon regeneration were performed. RESULTS: Percutaneous Achilles tenotomy was performed on 31 children (48 clubfeet) at a mean age of 5.24 ± 2.14 years (1-10.2 years). At a mean follow-up of 4.86 ± 1.97 years, all children demonstrated normal calf strength with mean dorsiflexion range of 13.64° (0-25°) and mean plantarflexion range of 37.95° (10-40°). The heel-rise endurance test was completed by 27 children with mean 25.85 heel rises/minute (range 17-30) and mean height of heel rise of 6.29 cm (range 4-10 cm). Normal fibrillar tendinous echotexture with homogenous echogenicity was seen on ultrasonography in 41 feet (85.4%) with mean tendon width of 9.7 mm (3.3-16 mm) and thickness of 5.1 mm (1.8-15 mm), comparable with unaffected feet. CONCLUSIONS: Clinical, functional and ultrasonographic parameters unequivocally demonstrate complete regeneration of the Achilles tendon, when pAT is performed in older children with delayed-presenting idiopathic clubfoot treated using Ponseti principles.

Complications of Percutaneous Tendo-Achilles Lengthening for Treatment and Prevention of Diabetic Foot Ulcers: A Systematic Review.

Percutaneous Achilles tendon lengthening is an effective surgical procedure to treat and prevent forefoot and midfoot ulcerations in patients with diabetes. Patients with diabetes are prone to plantar ulcerations due to a combination of factors, such as peripheral neuropathy, decreased tendon elasticity, peripheral vascular disease, and hyperglycemia. Complications such as re-ulceration and transfer lesion to the heel, associated with a calcaneal gait secondary to over-lengthening, are possible with percutaneous Achilles tendon lengthening. Although percutaneous Achilles tendon lengthening is well accepted, the overall incidence of complication has not been well described. A systematic review of the reported data was performed to determine the incidence of complication for percutaneous tendo-Achilles lengthening when used for the treatment and prevention of diabetic plantar ulcerations. Nine studies involving 490 percutaneous lengthening procedures met the inclusion criteria. The overall complication rate was 27.8% (8% with transfer heel ulcerations). Given the high rate of complications associated with a percutaneous Achilles tendon lengthening, careful patient selection and consideration of these risks should be considered prior to proceeding with this procedure. Additional prospective comparative analyses with standardization of surgical technique, degrees of lengthening achieved, and post-operative weightbearing and immobilization modalities are needed to decrease incidence of complication and achieve higher healing rates.

Optimised return to play: high treatment success rate in core muscle injury with surgical release of the anterior tendon of the rectus abdominis muscle and proximal tenotomy of the adductor longus muscle.

OBJECTIVES: Core muscle injury is a debilitating condition that causes chronic groin pain in athletes, particularly common in soccer players. The condition is characterised by pain in the inguinal region and can lead to a significant number of absences from high-intensity physical activity. It is caused by repetitive overload without proper counterbalance from the abdominal muscles, hip flexors, and adductors in susceptible athletes. Surgical indications for core muscle injury consider cases where non-surgical treatments have not provided sufficient relief. The aim of this study was to assess the results of surgical intervention for core muscle injury using the technique employed by the Sports Medicine Group of (Institute of Orthopedics and Traumatology of Hospital das Clínicas - Universidade de São Paulo). The procedure involves releasing the anterior portion of the tendon of the rectus abdominis muscle near the pubic symphysis, along with proximal tenotomy of the adductor longus muscle tendon. METHODS: This study utilised a consecutive historical cohort analysis of the medical records of 45 male athletes, of which, 75.6% were professional soccer players, who underwent surgical treatment between January 1, 2002, and December 31, 2021. The participants included active athletes aged between 18 and 40 years, with a mean age of 23.9 years, and were diagnosed with myotendinous core muscle injury. These athletes experienced pain in the pubic symphysis and adductor tendon region and had previously undergone medical treatment and physical therapy for a duration of three to six months without significant improvement. RESULTS: The average time for athletes to return to sport after surgery was 135 days, with a majority of participants being soccer and futsal players. The surgical intervention yielded promising results, with a positive correlation between unilateral injuries and the time taken to return to sport. The complication rate was low, at 6.7%. Notably, the rate of symptom resolution was high, at 93.3%. Furthermore, the analysis indicated that the player's position on the field significantly influenced the discharge period, suggesting that the game position plays a role in the recovery process. CONCLUSION: The combined surgical procedure involving the release of the rectus abdominis tendon and adductor longus muscle tenotomy demonstrates favourable outcomes for athletes with core muscle injury. This study provides strong support for the effectiveness of this surgical approach in managing the condition and offers a potential path to recovery and return to sports activities. STUDY DESIGN: Cross-sectional study.

Modified arthroscopic tenotomy of the extensor carpi radialis brevis for refractory lateral epicondylitis: a cohort study.

BACKGROUND: Different arthroscopic techniques exist for managing the extensor carpi radials brevis (ECRB) when treating refractory lateral epicondylitis. The purpose of this study is to compare the outcomes of a standard arthroscopic débridement with ECRB tendon release to an arthroscopic ECRB tenotomy distal to its insertion without débridement using a retrospective cohort study design. METHODS: This study included patients underwent arthroscopic treatment of lateral epicondylitis during 2 different time periods: 2016-2019 (débridement) and 2019-2021 (modified tenotomy without débridement). Patients were assessed preoperatively and at the last follow-up with Mayo Elbow Performance Score (MEPS), Disabilities of the Arm, Shoulder and Hand (DASH) score, Visual Analog Scale of pain. RESULTS: A total of 69 patients completed the follow-up (38 in the débridement group and 31 in the tenotomy group). Patients in both groups showed significant improvements were found in MEPS, DASH, and Visual Analog Scale after surgery. Patients in the tenotomy group had higher MEPSs and reported less pain with a minimum 2 year follow-up after surgery. DASH scores between groups were similar at all time periods. CONCLUSION: Arthroscopic modified tenotomy of the ECRB without débridement improves function and pain significantly for patients with refractory lateral epicondylitis, which is not inferior to arthroscopic débridement technique.

Biomechanics of subscapularis V-shaped tenotomy compared to standard tenotomy.

BACKGROUND: Subscapularis function is critical after anatomic total shoulder arthroplasty (aTSA). Recently, however, a technique has been described that features a chevron or V-shaped subscapularis tendon cut (VT). This biomechanical study compared repair of the standard tenotomy (ST), made perpendicular to the subscapularis fibers, to repair of the novel VT using cyclic displacement, creep, construct stiffness, and load to failure. METHODS: This biomechanical study used 6 pairs of fresh frozen paired cadaveric shoulder specimens. One specimen per each pair underwent VT, the other ST. Subscapularis tenotomy was performed 1 cm from the insertion onto the lesser tuberosity. For VT, the apex of the V was 3 cm from the lesser tuberosity. After tenotomy, each humerus underwent humeral head arthroplasty. Eight figure-of-8 sutures were used to repair the tenotomy (Ethibond Excel; Ethicon, US LLC). Specimens were cyclically loaded from 2 to 100 N at 45 degrees abduction at a rate of 1 Hz for 3000 cycles. Cyclic displacement, creep, and stiffness and load to failure were measured. RESULTS: Cyclic displacement did not differ significantly between the ST and VT from 1 to 3000 cycles. The difference in displacement between the V-shaped and standard tenotomy at 3000 cycles was 1.57 mm (3.66 ± 1.55 mm vs. 5.1 ± 2.8 mm, P = .31, respectively). At no point was the V-shape tenotomy (VT) >3 mm of average displacement, whereas the standard tenotomy (ST) averaged 3 mm of displacement after 3 cycles. Creep was significantly lower for VT in cycles 1 through 3. For all cycles, stiffness was not significantly different in the VT group compared with the ST group. Load to failure was not statistically significant in the VT compared to the standard tenotomy throughout all cycles (253.2 ± 27.7 N vs. 213.3 ± 76.04 N; P = .25, respectively). The range of load to failure varied from 100 to 301 N for standard tenotomy compared with 216 to 308 N for VT. CONCLUSION: This study showed that VT and ST demonstrated equivalent stiffness, displacement, and load to failure. VT had the benefit of less creep throughout the first 3 cycles, although there was no difference from cycle 4 to 3000. The VT had equivalent biomechanical properties to the ST at time zero, an important first step in our understanding of the technique. The VT technique warrants further clinical study to determine if the technique has clinical benefits over ST following aTSA.

Endoscopic Tendon Release for Iliopsoas Impingement After Total Hip Arthroplasty-Excellent Clinical Outcomes and Low Failure Rates at Short-Term Follow-Up.

PURPOSE: To investigate the clinical effectiveness of endoscopic iliopsoas tendon release (IPR) at the lesser trochanter (LT) in patients with iliopsoas impingement (IPI) after total hip arthroplasty (THA). METHODS: Between November 2017 and March 2021, a consecutive series of 36 patients were treated with endoscopic IPR for diagnosed IPI. Patients included had acetabular cup position confirmed by functional imaging (OPS, Corin, Pymble, NSW), typical clinical symptoms of IPI, and a positive response to diagnostic injection. Clinical assessment included validated patient-reported outcome measures (PROMs) along with hip flexion strength and active range of motion at different time marks up to 2-year follow-up, as well as surgical complications. RESULTS: Overall, 36 consecutive patients (11 males) with a mean age of 62 ± 12 years were included. All patients had failed nonoperative management. Dynamic computed tomography assessment was available in 89% of the patients, edge loading was reported in 10%, and variable cup overhang was reported in 50%. Clinically, PROMs were significantly improved at every time mark when compared with preoperative values (P < .001), showing the biggest improvement within the first 4 weeks after surgery. At the 6-month follow-up, peak isometric hip flexion strength on the operated side was 20% lower than the contralateral side (P < .001). Failure rate of the procedure was 2.8% (1 case). Linear regression showed no association between cup overhang and clinical outcomes. CONCLUSIONS: Endoscopic IPR at the LT is a safe and reproducible technique associated with significant and immediate improvement in pain, functional outcomes, and high patient satisfaction. With minimal short-term weakness, no complications, and only a single revision, even in cases with cup malposition and/or edge loading, we believe that endoscopic IPR can be considered as one of the first-line operative options in patients with symptomatic IPI, irrespective of component position. LEVEL OF EVIDENCE: Level IV, case series.

Determining the Optimal Treatment for Idiopathic Clubfoot: A Network Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Clubfoot, or congenital talipes equinovarus deformity, is a common anomaly affecting the foot in infants. However, clinical equipoise remains between different interventions, especially those based on the Ponseti method. The aim of this study was to examine the clinical outcomes of the various interventions for treating idiopathic clubfoot. METHODS: Searches of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Scopus, and CINAHL were conducted. Randomized controlled trials comparing different interventions, including the Ponseti method, accelerated Ponseti method, Ponseti method with botulinum toxin type A (Botox) injection, Ponseti method with early tibialis anterior tendon transfer (TATT), Kite method, and surgical treatment, were included. Network meta-analyses (NMAs) were conducted according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) reporting guidelines. The primary outcomes were the change in total Pirani score and maximal ankle dorsiflexion. Secondary outcomes were the number of casts, time in casts, and rates of tenotomy, total complications, relapse, adverse events, and additional required major surgery. RESULTS: Eleven randomized controlled trials involving 740 feet were included. According to the SUCRA (surface under the cumulative ranking curve)-based relative ranking, the Ponseti method was associated with the best outcomes in terms of Pirani score changes, maximal ankle dorsiflexion, number of casts, adverse events, and total complications, whereas the accelerated Ponseti method was associated with the best outcomes in terms of time in casts and tenotomy rate. Early TATT ranked best in terms of relapse rate. The Ponseti method with Botox injection was associated with the best outcomes in terms of the need for additional major surgery. CONCLUSIONS: The NMAs suggest that the Ponseti method is the optimal treatment overall, despite potential drawbacks such as longer time in casts and higher rates of tenotomy, relapse, and the need for additional surgery compared with other modified approaches. Therefore, clinicians should consider how treatments can be tailored individually. LEVEL OF EVIDENCE: Therapeutic Level I .

Surgical Options for Diabetic Toe Ulcers and Osteomyelitis Technical Tips and a Decision-Making Algorithm.

INTRODUCTION: Diabetic foot ulcers (DFUs) reflect a pivotal event that could lead to serious complications such as amputation and death. Although conservative surgery was reported to have better outcomes when compared to nonsurgical standard of care of forefoot wounds, the surgical management of diabetic toe ulcers (DTUs) is hardly researched. METHODS: The aim of this study is to describe the types and techniques of surgical procedures that could be needed when managing DTU. The proposed surgical techniques were based on their outcomes following an evidence-based search of the literature. RESULTS: Six major types of procedures could be used to treat DTUs; (1) interphalangeal joint resection arthroplasty, (2) phalangectomy or internal pedal amputation, (3) distal Syme amputation, (4) percutaneous toe flexor tenotomy, (5) toe fillet flap, and (6) toe amputation. Details on technical tips are described. CONCLUSION: Based on the location, ulcer grade of the ulcer and the status of the surrounding soft tissue, a surgical decision-making algorithm is proposed to assist surgeons when managing such prevalent conditions.Levels of Evidence: Level V: Expert review.

The Impact of Operative Correction of Equinus in Cerebral Palsy on Gait Patterns.

BACKGROUND: This study aimed to evaluate gait outcomes and strength following the surgical correction of equinus in cerebral palsy (CP) based on different surgical procedures. We included the Baumann and Strayer procedures, as well as the Achilles tendon lengthening (ATL). METHODS: A retrospective analysis was performed in patients with infantile, bilateral CP who received instrumental 3D gait analysis before and after surgical correction (18.66 months postoperatively). Patients were divided into 3 groups: Strayer surgery, Baumann surgery, and ATL. Gait performance and muscle strengths were compared between studied surgeries. RESULTS: A total population of 204 patients (15.43 years) with 341 operated lower limbs (LLs) was analyzed. Dorsiflexion in swing and stance phases significantly improved in all groups postoperatively. The Strayer and the ATL group showed higher postoperative dorsiflexion than the Baumann group. However, no loss of strength was observed with the Baumann method. Maximum power improved in this group postoperatively. An 8.2% loss in calf muscle strength was recorded in the Strayer group. CONCLUSION: Operative pes equinus treatment successfully improved the gait of children and adults with CP postoperatively. There were differences in postoperative results between studied operative techniques regarding range of motion and power. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

A single-center, single-blinded, randomized, parallel-group, non-inferiority trial to compare the efficacy of a 22-gauge needle versus a 15 blade to perform an Achilles tendon tenotomy in 244 clubfeet-study protocol.

BACKGROUND: Achilles tendon tenotomy is an integral part of the Ponseti method, aimed at correcting residual equinus and lack of dorsiflexion after correction of the adductus deformity in clubfoot. Percutaneous tenotomy using a number 15 scalpel blade is considered the gold standard, resulting in excellent results with minimal complications. The use of a large-bore needle to perform Achilles tendon tenotomies has been described in literature, but a large-scale randomized controlled trial is currently lacking. In this trial, we aim to show the non-inferiority of the needle tenotomy technique compared to the gold standard blade tenotomy technique. METHODS: We will randomize 244 feet into group A: needle tenotomy or group B: blade tenotomy. Randomization will be done using a block randomization with random block sizes and applying a 1:1 allocation to achieve an intervention and control group of the exact same size. Children will be evaluated at 3 weeks and 3 months post-tenotomy for primary and secondary clinical outcomes. The primary clinical outcome will be the range of dorsiflexion obtained the secondary clinical outcomes will be frequency of minor and major complications and Pirani score. The non-inferiority margin was set at 4°, and thus, the null hypothesis of inferiority of the needle technique will be rejected if the mean difference between both techniques is less than 4°. The statistical analysis will use a multi-level mixed effects linear regression model for the primary outcomes and a multi-level mixed effects logistic regression model for the secondary clinical outcomes. The physician performing the evaluations post-tenotomy will be the only one blinded to group allocation. TRIAL REGISTRATION: This trial was registered prospectively with ClinicalTrials.gov registration number: NCT04897100 on 21 May 2021.

What happens to endoscopic/arthroscopic tenotomies with iliopsoas impingement in the medium term? Review of a prospective cohort of 64 patients with a minimum follow-up of 5 years.

INTRODUCTION: The occurrence of iliopsoas impingement (IPI) after total hip arthroplasty (THA) is a proven risk factor for negative outcomes. Endoscopic or arthroscopic tenotomies of the iliopsoas offer a surgical solution with short-term results that have already been validated in prospective multicenter series. We carried out a review of the patients at more than 5 years of follow-up in order to assess the stability of the results over time. HYPOTHESIS: Our main hypothesis was that endoscopic/arthroscopic tenotomies allow stable medium-term resolution of the painful symptoms of IPI. Our secondary hypothesis was that medium-term survival was satisfactory. MATERIAL AND METHOD: This study is a continuation of a multicenter prospective series. Patients were contacted through multiple channels in order to: obtain an Oxford score, assess for satisfaction, psoas irritation, and daily pain on a visual analogue scale (VAS). RESULTS: Of 64 patients in the original study, 57 were contacted. The Oxford score at the last follow-up was 40.7±7.7 [12-48]. There was a significant difference between the Oxford scores preoperatively, at 8 months and at the last follow-up. The mean satisfaction out of 10 was 8.0±2.1 [1-10]. We found 84% satisfaction at 5 years against 83% at 8 months. The VAS was 2.1±2.3 [0-10]. A straight leg psoas sign was present in 19.6% (10/51) of patients at 5 years, compared to 15.6% (8/51) at 8 months. The sign disappeared in four cases, while it reappeared during the interval in six cases. Survival was 91.2% (95% CI: 80.2-96.3) at 5 years. CONCLUSION: Endoscopic/arthroscopic iliopsoas tenotomies represent a permanent medium-term solution to treat IPI after THA. The existence of a force differential or an acetabular overhang does not seem, within a certain limit, to impact the results in the medium term.

Tenotomy or tenodesis versus conservation of the long head of the biceps tendon in the repair of isolated supraspinatus tears: A systematic review of the literature.

BACKGROUND: Few studies have directly compared the outcomes of rotator cuff repair (RCR) with or without concomitant LHBT tenotomy or tenodesis. The aim of this literature review was to assess: (i) whether an adjuvant procedure on the LHBT at the time of RCR gives better functional results than RCR alone; and (ii) whether reoperation rates are higher after RCR alone or RCR+tenotomy or tenodesis. METHODS: A literature search was carried out on PubMed, MEDLINE, Embase, Web of Science and the Cochrane database for papers published in English or French between 1st January, 2010, and 31st December, 2021. Included studies compared the results of RCR alone with RCR+concomitant tenotomy or tenodesis in patients with tears of the supraspinatus tendon or rotator cuff. ARTICLES: A total of 626 articles were identified in the literature search and 168 were retained for more detailed examination. Forty-seven articles were read in their entirety and nine articles comparing RCR with or without concomitant tenotomy or tenodesis of the LHBT were retained for the analysis. RESULTS: Nine articles comparing the results of RCR alone versus RCR+LHBT tenotomy or tenodesis were reviewed. The majority of patients were more than 50 years old and male. The rate of lesions to the LHBT in the studies included ranged from 26.8-60.2%. Eight of the nine studies compared the functional results of RCR alone versus RCR+tenotomy or tenodesis, with six reporting no significant difference, one reporting better outcomes after concomitant biceps surgery and one reporting worse outcomes after a biceps procedure. DISCUSSION: This review did not provide a strong answer to our questions, owing to the heterogenicity of clinical evaluation and low level of evidence of the studies. However, it appears that in the absence of biceps pathology or in the presence of small lesions, the LHBT could be preserved. The rate of revision did not seem to be higher and cuff healing lower in this situation. Therefore, further randomized studies are required to identify the role of concomitant procedure of the biceps in case of small isolated supraspinatus repair.

Modified arthroscopic intra-articular transtendinous looped biceps tenodesis leads to satisfactory functional outcomes and less frequent Popeye deformity compared to biceps tenotomy.

PURPOSE: The present study aimed to propose a modified intra-articular transtendinous looped biceps tenodesis (mTLBT) using a suture anchor and to compare the functional outcomes and incidence of Popeye deformities between biceps tenotomy and mTLBT. METHODS: Medical records of patients who underwent either tenotomy or mTLBT for the long head of the biceps tendon (LHBT) lesion between January 2016 and April 2021 were retrospectively reviewed. The inclusion criteria were patients aged 40-70 years with LHBT pathologies, such as superior labrum anterior to posterior (SLAP) lesions > type II, LHBT pulley system rupture with bicipital instability, and intra-articular LHBT tear. The exclusion criteria were full-thickness supraspinatus tears, frozen shoulder, shoulder fracture, and postoperative traumatic events that affected the operated shoulder. All patients were followed up for at least 1 year. Popeye deformity, bicipital cramping pain, visual analog scale (VAS) pain score, and functional outcome scores (University of California at Los Angeles [UCLA] and American Shoulder and Elbow Surgeons [ASES] scores) were recorded. Fisher's exact test and Chi-square test were used for categorical variables, whereas the Mann-Whitney U test was used for nonparametric variables. RESULTS: The mTLBT and tenotomy groups included 15 and 40 patients, respectively. The incidence of Popeye deformity and biceps cramping pain in the tenotomy group (52.5% and 50%, respectively) was significantly higher than that in the mTLBT group (13.3% and 20%, respectively) (p = 0.009 and p = 0.045, respectively). The postoperative VAS, UCLA, and ASES scores were not significantly different between the two groups. One patient in the tenodesis group experienced metallic-anchor pullout. CONCLUSION: mTLBT is an arthroscopic intra-articular top of the groove tenodesis that can be performed completely in the intra-articular space and is especially suitable for patients with an intact or partially torn rotator cuff. This technique is reliable for treating biceps pathologies as it results in similar functional outcome scores, lesser biceps cramping pain, and less frequent Popeye deformity compared to biceps tenotomy.

Exploring Bracing Adherence in Ponseti Treatment of Clubfoot: A Comparative Study of Factors and Outcomes in Uganda.

The Ponseti method of clubfoot treatment involves two phases: initial correction, usually including tenotomy; and bracing, to maintain correction and prevent relapse. Bracing should last up to four years, but in Uganda, approximately 21% of patients drop from clinical oversight within the first two years of using the brace. Our study compared 97 adherent and 66 non-adherent cases to assess the influential factors and effects on functional outcomes. We analyzed qualitative and quantitative data from clinical records, in-person caregiver interviews, and assessments of foot correction and functionality. Children who underwent tenotomy had 74% higher odds of adherence to bracing compared to those who did not undergo tenotomy. Conversely, children from rural households whose caregivers reported longer travel times to the clinic were more likely to be non-adherent to bracing (AOR 1.60 (95% CI: 1.11-2.30)) compared to those without these factors. Adhering to bracing for a minimum of two years was associated with improved outcomes, as non-adherent patients experienced 2.6 times the odds of deformity recurrence compared to adherent patients. Respondents reported transportation/cost issues, family disruptions, and lack of understanding about the treatment method or importance of bracing. These findings highlight the need to address barriers to adherence, including reducing travel/waiting time, providing ongoing education for caregivers on bracing protocol, and additional support targeting transportation barriers and household complexities.

Indication for Achilles Tenotomy in Congenital Clubfoot: Effectiveness of Using the Tibio-Plantar Fascia Angle as a Radiographic Parameter.

Congenital clubfoot is one of the most common deformities in children, and currently, the Ponseti method is used worldwide because of its favorable short-term results. With the Ponseti method, the indication for Achilles tenotomy is traditionally based on only physical examination findings; however, some surgeons have also utilized plain radiographs. Because using physical examinations to determine the degree of hindfoot dorsiflexion for the indication of tenotomy can lead to underestimation. We developed and utilized the effectiveness of the tibio-plantar fascia angle (Ti-P angle) in the lateral maximum dorsiflexion view in determining the need for Achilles tenotomy. A retrospective analysis of consecutive 26 patients with congenital idiopathic clubfeet (37 feet) was performed. Whether Achilles tenotomy was indicated was determined based on physical examination for a former period (Group P). For the latter period, whether tenotomy was indicated was determined by referencing radiographs (Group X). No significant differences were found in any of the background factors or severity between Group P and Group X. Cases with larger tibiocalcaneal and Ti-P angles were more likely to require Achilles tenotomy or additional soft tissue release. An angle of more than 72° of the Ti-P angle demonstrated adequate specificity for the indication of Achilles tenotomy. The radiographic lateral tibio-plantar fascia angle is useful for deciding whether a tenotomy needs to be performed.

Percutaneous ultrasound-guided needle tenotomy for treatment of chronic tendinopathy and fasciopathy: a meta-analysis.

OBJECTIVES: To systematically assess the efficacy of percutaneous ultrasound-guided needle tenotomy (PUNT) in the treatment of chronic tendinopathy and fasciopathy. METHODS: A comprehensive literature search was performed with the following search terms: tendinopathy, tenotomy, needling, Tenex, fasciotomy, ultrasound-guided, and percutaneous. Inclusion criteria consisted of original studies evaluating pain or function improvement after PUNT. Meta-analyses investigating standard mean differences were performed to assess the pain and function improvement. RESULTS: Thirty-five studies with 1674 participants (1876 tendons) were enrolled in this article. Of which 29 articles were included in meta-analysis and the remaining 9 articles without enough numeric data were included in descriptive analysis. PUNT significantly alleviated pain with the standard mean difference of 2.5 (95% CI: 2.0-3.0; p < 0.05), 2.2 (95% confidence interval (CI): 1.8-2.7; p < 0.05), and 3.6 (95% CI: 2.8-4.5; p < 0.05) points in short-term, intermediate-term, and long-term follow-up intervals, respectively. It was also associated with marked improvement in function with 1.4 (95% CI: 1.1-1.8; p < 0.05), 1.8 (95% CI: 1.3-2.2; p < 0.05), and 2.1 (95% CI: 1.6-2.6; p < 0.05) points, respectively in short-term, intermediate-term, and long-term follow-ups. CONCLUSION: PUNT improved pain and function at short-term intervals with persistent results on intermediate- and long-term follow-ups. PUNT can be considered an appropriate minimally invasive treatment for chronic tendinopathy with a low rate of complications and failures. CLINICAL RELEVANCE: Tendinopathy and fasciopathy are two common musculoskeletal complaints that can cause prolonged pain and disability. PUNT as a treatment option could improve pain intensity and function. KEY POINTS: • The best improvement in pain and function was achieved after the first 3 months following PUNT and was continued to the intermediate- and long-term follow-ups. • No significant difference was found between different tenotomy methods in terms of pain and function improvement. • PUNT is a minimally invasive procedure with promising results and low complication rates for treatments of chronic tendinopathy.
