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.

Background Optimal treatment of the diseased long head of the biceps (LHB) tendon during rotator cuff repair remains a topic of debate: tenotomy or tenodesis. A recent meta analysis revealed no difference in strength or functional outcome between treatments. The included studies varied in methodological quality, and only two were randomized controlled trials (RCTs). As strong evidence in favor of either tenotomy or tenodesis is still lacking, we designed this randomized controlled trial to compare functional outcomes after tenotomy and tenodesis when performed in adjunct to arthroscopic rotator cuff repair. Methods Patients older than 50 years with a supraspinatus and/or infraspinatus tendon rupture sized smaller than 3 cm, who are encountered with LHB pathology, will be randomized to either LHB tenotomy or LHB tenodesis. Clinical and patient-reported data will be collected pre-operatively, 6 weeks, 3 months and 1 year after surgery. Primary outcome is overall shoulder function evaluated with the Constant score at 1 year after surgery. As additional measures of shoulder function, two patient reported outcomes (the Dutch Oxford Shoulder Test and the Disabilities of the Arm Shoulder and Hand questionnaire) will be assessed. Other evaluations include cosmetic appearance evaluated by the “Popeye” deformity, elbow flexion strength, arm cramping pain, MRI-based location of the biceps tendon, quality of life, and duration of surgery. To detect non-inferiority with a one-sided, two-sample t-test with 80 % power and a significance level (alpha) of 0.025, the required sample size is 98 patients. Discussion Treatment of LHB tendon lesions is performed differently around the world and meta analyses do not provide conclusive evidence in favor of one of these treatments. This study will strengthen evidence on the risks and benefits of LHB tenotomy and tenodesis in adjunct to a rotator cuff repair, which is important for managing patient expectations.

IntroductionCurrently there exists no clear evidence concerning the surgical treatment of LHB lesions with either tenotomy or tenodesis. The aim of the study is therefore to evaluate elbow flexion and forearm supination force as well as the biceps muscle distalization according to both techniques in isolated LHB lesions.MethodsConsecutive patients aged 40–70 years with shoulder arthroscopies for isolated SLAP or biceps pulley lesions were prospectively randomized to arthroscopic suprapectoral intraosseous LHB tenodesis or tenotomy. Pre-, 6 and 12 months postoperatively, the SST, ASES, Constant–Murley and LHB scores were recorded. The elbow flexion force was measured in 10°/90° flexion, the supination force in neutral/pronation position. In addition, the maximum upper-arm circumference and its position relative to the radial epicondyle of the humerus were evaluated preoperatively and in follow-up.Results20/22 patients (mean age 52.0 ± 8.5; range 36–63 years, 11 male) completed the follow-up. 9/20 were treated with LHB tenodesis (mean age 51.5 ± 9.5; range 37–63 years, 7 male) and 11/20 with tenotomy (mean age 52.8 ± 8.0; range 36–62 years, 4 male). The force measurements and scores showed no significant difference after 12 months. Tenodesis achieved a significant increase in force 6 months postoperatively compared to preoperatively. One tenodesis patient and three tenotomy patients showed a postoperative popeye-sign deformity.ConclusionThis prospective randomized study comparing LHB tenodesis and tenotomy in isolated LHB lesions has shown no significant difference in elbow flexion and forearm supination force and clinical scores after 12 months. After LHB tenotomy, there was a non-significant trend for a higher rate of popeye-sign deformities of the upper arm and biceps muscle cramps.

Background Hip replacement surgery is highly effective in relieving pain and improving mobility in patients with various hip conditions. However, some patients develop groin pain after surgery, often due to iliopsoas impingement (IPI), which can be challenging to diagnose. Conservative treatments are initially recommended, but when these are not effective, surgical options may be considered. This study aims to evaluate the clinical outcomes, success and failure rates, revision rates, and complications associated with arthroscopic and endoscopic surgery for IPI, thereby providing a comprehensive understanding of the effectiveness and risks of these surgical interventions. Materials and methods A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, including a thorough search of five main databases: PubMed, Scopus, Embase, Medline, and Cochrane. Eligible articles were meticulously evaluated according to predefined criteria for levels of evidence (LoE), with retrospective studies assessed using the Coleman Methodology Score (mCMS). This systematic review was registered in the International Prospective Registry of Systematic Reviews (PROSPERO). Results Among the 16 included studies, 431 patients with 434 hips underwent either endoscopic or arthroscopic tenotomy. Both techniques showed favorable outcomes, with arthroscopic tenotomy demonstrating slightly higher success rates than endoscopic tenotomy. Common complications included mild pain and occasional infections, with recurrence observed in some cases. Both techniques offer direct visualization of prosthetic components and potential preservation of psoas function. Conclusions Arthroscopic and endoscopic iliopsoas tenotomy are effective treatments for alleviating symptoms and improving hip function in patients with IPI post-total hip arthroplasty (THA). Level of evidence IV.

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.

PurposeFlexor tendon repair consists of circumferential peripheral sutures in combination with core sutures to avoid fraying and reduces the exposure of suture material on tendon surface. The peripheral suture adds up to a tenfold increase of the biomechanical stability compared to the core suture alone. The purpose of our study was to determine the most favourable peripheral repair technique for tendon repair.MethodsSeventy-two porcine flexor tendons underwent standardized tenotomy and repair using one of the following six methods (n = 12): simple-running (SR), simple-locking (SL), Halsted-mattress (HM), lin-locking (LL), Lembert-mattress (LM), and Silfverskiöld cross-stich (SCS) suture technique. The SL- suture was placed 2 mm; the HM, LM, SC, and LL suture were placed 5 mm from the tendon gap. The SR suture was placed 1, 2, and 3 mm from tendon ends; no additional core suture was applied. For cyclic testing (1000 cycles), elongation was calculated; for load to failure construct stiffness, yield load and maximum load were determined.ResultsThe mean cyclic elongation for all tested suture techniques was less than 2 mm; there was no significant difference between the groups regarding elongation as well as yield load. The HM, LM, SCS, and LL suture techniques presented significantly higher maximum loads compared to the SR- and SL-sutures. The 3 mm SR showed significantly higher maximum loads compared to the 2 and 1 mm SR.ConclusionsBeside the distance from tendon gap, the type of linkage of the suture material across and beneath the epitendineum is important for biomechanical stability. Simple-running suture is easy to use, even with a slight increase of the distance from tendon gap significantly increases biomechanical strength. For future repairs of flexor tendon injuries, 3 mm stitch length is highly recommended for simple peripheral suture, while the Halsted-mattress suture unites the most important qualities: biomechanically strong, most part of suture material placed epitendinous, and not too complicated to perform.

Background Atrophy of the gluteus medius and gluteus minimus has been reported in patients with developmental dysplasia of the hip (DDH). We aimed to investigate whether atrophy of the gluteus medius and gluteus minimus is associated with DDH. Methods Twenty white New Zealand rabbits were divided into 2 groups in our experiment. In group 1, one limb of each rabbit was randomly selected for tenotomy of the gluteus medius and gluteus minimus, with the other side serving as a sham control. In group 2, one limb of each rabbit was randomly selected for intramuscular injection of botulinum toxin to induce atrophy of the gluteus medius and gluteus minimus, with the other side serving as a sham control by injection of equal volumes of normal saline. Acetabulum and muscles were evaluated by ultrasound, X-ray imaging, shear wave elastography, and histology with hematoxylin‐eosin (H&E) staining. Results Atrophy of the gluteus medius and gluteus minimus was observed on the experimental side in both groups. Early dysplastic changes in the hips on the tenotomy side was observed on the radiographs with an increased acetabular index (40.0 ± 6.7° vs 24.1 ± 1.9°, P  < 0.001) compared with the control side in group 1. No dislocation of the hips was observed. No dysplasia of the hips was observed on the botulinum–toxin side in group 2 with similar acetabular index on both sides (25.0 ± 3.7° vs 24.1 ± 1.9°, P  = 0.13). Conclusions Tenotomy, not atrophy, of the gluteus medius and gluteus minimus is associated with early changes of DDH.

Background As payment models shift toward a focus on value and reimbursement becomes increasingly tied to quality and patient experience, minimizing unexpected acute health needs has become a priority for both policymakers and clinical leaders. Despite recent emphasis on emergency department (ED) visits as a quality measure in surgery, little is known about the role of the ED in the early postoperative period after hand surgery. Questions/purposes The purpose of this study was to determine the rates, reasons, and factors associated with ED visits within 30 days of elective outpatient hand surgery. Methods Using our institutional database for 2009 through 2013, we assessed ED visit rates for 2332 patients undergoing carpal tunnel or trigger finger release. Medical records were manually reviewed to ascertain the primary reason for the ED visit. Multivariable logistic regression modeling was used to identify factors independently associated with ED use. Results A total of 67 patients (3%) experienced at least one ED visit within 30 days of hand surgery (carpal tunnel: 3%; trigger finger: 3%). Most visits (66%) occurred within the first 2 weeks of surgery, and 31% led to hospitalization. The most common reasons for ED visits were pain (18%) and wound issues (16%). Unmarried and medically infirm patients were more likely to visit the ED. Conclusions ED visits after hand surgery are common, often related to the procedure, and potentially responsive to quality improvement initiatives. Targeted efforts to educate patients about pain management, wound care, and the expected course of recovery before surgery, together with close postoperative contact (eg, routine phone calls, facsimile correspondence by email, or secure messaging) may limit visits to the ED.

The hip is a highly stable joint. Non-traumatic dislocation of the hip is extremely uncommon. In this article, we report two cases of non-traumatic hip dislocations following hip arthroscopy. In both cases, capsulotomy and ileopsoas tenotomy had been performed. These cases raise questions about the importance of the natural stabilisers of the hip. Level of evidence V.

Purpose To assess if pes anserinus tenotomy (PAT) during definitive open reduction and internal fixation (ORIF) of tibial plateau fractures is associated with a decreased risk of surgical site infection (SSI) and other postoperative complications. Methods A retrospective review of all adults who underwent ORIF for tibial plateau fractures from April 2005 to February 2022 at single level 1 trauma center was performed. Patients who had a medial approach to the plateau with minimum three-month follow-up were required for inclusion. All patients with fasciotomy for compartment syndrome or with traumatically avulsed or damaged pes anserinus prior to ORIF were excluded. Two groups were created: those who received a pes anserinus tenotomy with repair (PAT group) and those whose pes anserinus were spared and left intact (control group). Patient demographics, injury and operative characteristics, and surgical outcomes were compared. The primary outcomes were rates of deep and superficial SSI. Results The PAT group had significantly lower rates of deep SSI (9.2% vs. 19.7%, P  = 0.009), superficial SSI (14.2% vs. 26.5%), P  = 0.007), and any SSI (15.8% vs. 28.9%, P  = 0.005). Multiple logistic regression showed that heart failure (aOR = 7.215, 95% CI 2.291–22.719, P  < 0.001), and presence of open fracture (aOR = 4.046, 95% CI 2.074–7.895, P  < 0.001) were independently associated with increased odds of deep SSI, while PAT was associated with a decreased odds of deep SSI (aOR = 0.481, 95% CI 0.231–0.992, P  = 0.048). PAT had significantly lower rates of unplanned return to the operating room (20.8% vs. 33.7%, P  = 0.010) and implant removal (10.0% vs. 18.0%, P  = 0.042). Conclusion While these data do not allow for discussion of functional recovery or strength, pes anserinus tenotomy was independently associated with significantly lower rates of infection, unplanned operation, and implant removal.
