Can we accelerate rehabilitation following reverse shoulder arthroplasty? A systematic review.

Background: There is no consensus concerning the rehabilitation protocol following reverse shoulder arthroplasty. Several patients are expecting to be able to use their arms for sports or recreation shortly after their operation. Methods: This review was designed as an intervention systematic review with narrative analysis. Authors searched English literature in PubMed and Embase databases from 1/1/1989 until July 2022. Controlled studies comparing rehabilitation protocols for patients undergoing reverse shoulder arthroplasty were included. Data quality was examined with the Cochrane risk of a bias assessment tool for randomized trials, the Methodological Index for Non-Randomized studies (MINORS) tool, as well as the Grading of Recommendations Assessment Development and Evaluation (GRADE) approach. Results: Three studies were finally analyzed. At 3 months post-op, forward flexion was found to be significantly higher in the early rehabilitation group (140.5, 95% confidence intervals (CIs): 135.10-145.89; the delayed rehabilitation group mean was 131.24, 95% CI: 125.73-136.74; p = 0.019). Twelve months post-op, no significant difference in any clinical or patient-reported outcome was shown. More complications were reported in the 6 weeks-delayed rehabilitation group. Discussion: Newer regimes permit immediate shoulder mobilization but may not be applied to every patient. The lack of strong evidence warrants the need for future controlled studies; subsequently, postoperative rehabilitation should be individualized.

A Novel Surgical Technique for the Reconstruction of Chronic Tennis Leg Injury.

Tennis leg, a rupture of the medial head of the gastrocnemius muscle at the musculotendinous junction (MTJ), is common, particularly among middle-aged sports enthusiasts. While acute cases usually resolve with conservative care, optimal surgical strategies for the treatment of chronic injuries remain undefined. This study reviews the current literature and details the successful operative treatment of a 37-year-old male with a 12-month history of tennis leg, employing a novel reverse flap technique from the MTJ's aponeurosis and augmented by a facia lata allograft.

Bracing with Tape and Extensor Refixation of Elbow with Posterolateral Instability Due to Cubitus Varus: A Case Report.

CASE: A 54-year-old patient had lateral ligament insufficiency due to cubitus varus from a childhood supracondylar fracture. Arthrolysis/synovectomy and at a later stage double-row extensor origin refixation and lateral ulnar collateral ligament bracing with nonabsorbent tape and anchors were performed. Follow-up at 3, 6, 12, and 24 months showed excellent Mayo Elbow Performance and Disabilities of Arm, Shoulder, and Hand Scores (24-month follow-up = 100 and 2.5, respectively). CONCLUSION: Suture tape augmentation and double-row extensor refixation in cases of lateral collateral ligament complex insufficiency due to cubitus varus may provide improved short-term functional outcomes, from the third postoperative month.

Risk for Fracture with Acromioclavicular Joint Reconstruction and Strategies for Mitigation.

Acromioclavicular (AC) joint injuries are a common cause of shoulder pain, especially among athletes. Surgical reconstruction of the AC joint can lead to complications such as fracture of the coracoid process, clavicle or acromion, which can negatively affect the patient's outcome. The purpose of this review is to discuss the risk factors for fractures associated with AC joint reconstruction, as well as the strategies that can be used to mitigate this risk. Risk factors for fractures include low mineral density, coracoid/clavicle drilling, larger holes in the coracoid, and the number of tunnels used for reconstruction.

Arthroscopic Modified Elbow Lateral Collateral Ligament Imbrication: An Operative Technique.

When the lateral collateral ligament (LCL) complex fails to support the radiocapitellar and ulnohumeral joints in advanced stages of insufficiency, the patient experiences posterolateral rotatory instability (PLRI). Open lateral ulnar collateral ligament repair with a ligamentous graft has been the standard treatment for PLRI. Despite producing good clinical stability rates, this method is associated with significant lateral soft-tissue dissection and a lengthy recovery period. By fastening the LCL to its humeral insertion, arthroscopic imbrication of the LCL can increase stability. The senior author modified this technique. With the aid of a passer, the LCL complex, lateral capsule, and anconeus may be weaved with a single (doubled) suture, secured with a Nice knot. LCL complex imbrication may be used to restore stability and improve pain and function in patients with grade I and II PLRI.

Medial patellofemoral ligament reconstruction using patella bone tunnel techniques with or without implants. A systematic review of outcomes and complications.

PURPOSE: Τhe main goal of this study was to compare the clinical results, including the complication rates and patient-reported outcomes, in patients who underwent surgery for recurrent patellar dislocation using different patellar tunnel fixation techniques. This study compared Medial Patellofemoral Ligament (MPFL) reconstruction implant free techniques against ones that used implants. METHODS: The present systematic review was conducted according to the PRISMA guidelines. The literature search was conducted in January 2023. We included patients who underwent isolated MPFL reconstruction for recurrent patellar instability. Patients with confirmed concomitant or prior ipsilateral knee procedures, multiligament injury, severe patellar dysplasia or less than 6 months of follow-up were excluded. MINORS and MCMS scores were used for the assessment of methodological quality. RESULTS: Data from 750 procedures were collected, of which 284 used implants to perform the procedure while in 455 an implant-free technique was used. Patient age at the time of surgery ranged from 11 to 60 years while the follow-up time of the studies ranged between 3 and 108 months. Postoperative Kujala (0.3, p = 0.89) and Lysholm (1.2, p = 0.26) scores were better in the implant-free techniques compared to implant-based. A higher rate of recurrent dislocation (OR 0.51; 95% CI 0.10-2.54, p = 0.4), subluxation (OR 0.20; 95% CI 0.40-0.88, p = 0.019) and stiffness (OR 0.76; 95% CI 0.33-1.72, p = 0.55) was noted in the implant-free techniques, while the implant-based techniques displayed increased incidence of patella fractures (OR 3.12; 95% CI 0.77-12.6, p = 0.09), reoperation (OR 1.69; 95% CI 0.78-3.65, p = 0.17) and infection (OR 2.07; 95% CI 0.46-9.32, p = 0.33). CONCLUSION: There was no significant difference between the 2 techniques in terms of patient reported outcomes. Regarding complications, MPFL reconstruction using implants demonstrated significant higher rate of patella fractures while the implant free technique showed a greater risk of subluxation.

Endoscopic-Assisted Hamstring Tendon Harvesting.

Efficient hamstring tendon harvesting is a crucial part of anterior cruciate ligament reconstruction surgery using autografts. Harvesting of the gracilis and semitendinosus tendons is usually performed using an open approach, exposing the distal tibial attachment of the tendons at the pes anserinus and proceeding using a tendon stripper without direct tendon visualization. The success of the anterior cruciate ligament reconstruction surgery strongly depends, among other factors, on the preservation of the hamstring tendon length and integrity. Inadequate tendon release from their attachments and improper use of the tendon stripper, in addition to poor intraoperative visibility, may lead to premature tendon amputation, endangering the success of the operation. We describe an endoscopic-assisted technique of hamstring tendon harvesting that provides complete visualization of the tendons from the tibia attachment to the musculotendinous junction. The procurement of the tendons is completed under direct vision using any tendon stripper. This surgical technique offers a way to minimize complications that may arise during the standard open tendon harvesting techniques without additional visualization.

Morphometric MRI Evaluation of Three Autografts Used in Anterior Cruciate Ligament Reconstruction in Athletes.

The purpose of the present study was to quantify the morphometric characteristics of three tendon autografts (hamstring tendons (HT), quadriceps tendon (QT), and patellar tendon (PT)) used in anterior cruciate ligament (ACL) reconstruction. For this purpose, knee magnetic resonance imaging (MRI) was obtained in 100 consecutive patients (50 males and 50 females) with an acute, isolated ACL tear without any other knee pathology were used. The level of the physical activity of the participants was determined using the Tegner scale. Measurements of the tendons' dimensions (PT and QT tendon length, perimeter, cross-sectional area (CSA), and maximum mediolateral and anteroposterior dimensions) were performed perpendicular to their long axes. Higher values were recorded as regards the mean perimeter and CSA of the QT in comparison with the PT and the HT (perimeter QT: 96.52 ± 30.43 mm vs. PT: 63.87 ± 8.45 mm, HT: 28.01 ± 3.73 mm, F = 404.629, p < 0.001; CSA QT: 231.88 ± 92.82 mm2 vs. PT: 108.35 ± 28.98 mm2, HT: 26.42 ± 7.15 mm2, F = 342.415, p < 0.001). The length of the PT was shorter in comparison with the QT (53.1 ± 7.8 vs. 71.7 ± 8.6 mm, respectively, t = -11.243, p < 0.001). The three tendons showed significant differences in relation to sex, tendon type, and position as regards the perimeter, CSA, and the mediolateral dimensions but not for the maximum anteroposterior dimension.

Biomolecules Related to Rotator Cuff Pain: A Scoping Review.

The pathophysiology of pain in patients suffering from rotator cuff (RC) tendinopathy or tears has been examined in various ways. Several molecules from tissue samples taken from the subacromial bursa, supraspinatus tendon, glenohumeral joint fluid, and synovium as well as from peripheral blood have been investigated. This article explores these studies, the assessed biomarkers, and groups their results according to the status of tendon integrity (tendinopathy or tear). Through a structured PubMed database search, 9 out of 658 articles were reviewed. Interleukins, mostly IL-1b and its antagonist, IL-1ra, matrix Metalloproteinases (MMPs), the vascular endothelial growth factor (VEGF) and TNF-a are biomarkers directly searched for correlation to pain level. Most studies agree that IL-1b is directly positively correlated to the degree of pain in patients with RC tendinopathy, especially when the examined sample is taken from the subacromial bursa. VEGF, and TNF-a have been related to shoulder pain preoperatively and TNF-a has also been linked with sleep disturbance. Further studies pointing to more biomarkers taken from the subacromial bursa or tendon directly relating to pain degree are warranted.

A Low Virulence Infective Tenosynovitis Triggered by a Neisseria Species.

A persistent infective tenosynovitis, caused by a non-pathogenic Neisseria species and involving the little finger and the thumb of a middle-aged woman, forming a horseshoe-type infection is presented. An extensive volar approach was utilised for excision of the granulomatous synovium and drainage of turbid fluid. Neisseria spp was isolated by tissue microbiology and targeted antibiotic therapy for 6 weeks was required to eradicate infection. The presence of low virulence microorganisms which might act as true pathogens should always be considered as a causative factor leading to persistent infections that require open surgical debridement and washout. Level of Evidence: Level V (Therapeutic).

Outcomes of Arthroscopic Nerve Release in Patients Treated for Large or Massive Rotator Cuff Tears and Associated Suprascapular Neuropathy: A Prospective, Randomized, Double-Blinded Clinical Trial.

BACKGROUND: Suprascapular neuropathy has been observed in the setting of rotator cuff tears (RCTs), but its association with these tears and their treatment are unclear. HYPOTHESIS: Arthroscopic suprascapular nerve release during rotator cuff repair will not alter the outcomes of neuropathy. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: A total of 42 patients with large/massive reparable RCTs and suprascapular neuropathy were recruited and followed up at 6 and 12 months. Electrophysiological results as well as Disabilities of the Arm, Shoulder and Hand (DASH), American Shoulder and Elbow Surgeons (ASES), and Constant scores were evaluated at selected time periods. Patients were randomly assigned to 2 groups. Patients in the control group underwent arthroscopic repair of the rotator cuff without combined arthroscopic release of the superior transverse scapular ligament; in the second group, the superior transverse ligament was released. The primary outcome was to examine full suprascapular nerve recovery through electrophysiological changes between groups. The secondary/tertiary outcomes were analysis of clinical outcomes and assessment of the relation between RCT size and the degree of suprascapular nerve recovery. Patients, clinical staff members, and the neurologist were blinded to the type of surgical procedure. RESULTS: Of 42 patients, 37 completed the follow-up at 12 months (median age, 64 years [range, 50-75 years]). Overall, 17 of 19 (89.5%) patients in the control group and 15 of 18 (83.3%) patients in the nerve release group had full nerve recovery, with no significant difference between the 2 groups. Clinically, all patients in both groups showed a significant improvement (P < .001), but no significant difference was observed between the 2 groups in terms of 12-month postoperative scores (control group: DASH: median, 5 [range, 0-21]; ASES: median, 88 [range, 83-98]; Constant: median, 86 [range, 70-98]) (nerve release group: DASH: median, 6 [range, 0-25]; ASES: median, 90 [range, 83-98]; Constant: median, 88 [range, 75-98]). Also, no significant difference was found between the 2 groups regarding other secondary and tertiary outcomes. CONCLUSION: Combined arthroscopic release of the superior transverse scapular ligament and rotator cuff repair in patients with large/massive RCTs and suprascapular neuropathy did not produce statistically significant improved outcomes compared with repair of the rotator cuff alone. REGISTRATION: NCT02318381 (ClinicalTrials.gov identifier).

The role of structured physiotherapy in treating patients with atraumatic shoulder instability: Medium term results from a case series.

BACKGROUND: Consensus favours conservative treatment for atraumatic shoulder instability, but literature is scarce on the topic. We therefore prospectively assessed the results of structured physiotherapy for these patients. METHODS: Patient reported outcomes were recorded prior to physiotherapy and on discharge. Notes review identified patients re-referred for the same condition. RESULTS: N = 85. Review range was 12-72 months post-treatment. Median Oxford Shoulder Instability Score (OSIS) improved from 21 (range: 2-47) to 39 (11-47). Median Western Ontario Shoulder Instability Index (WOSI) improved from 1117 (range: 306-2028) to 485 (0-1569). Patients with posterior instability demonstrated better results compared with other groups (OSIS change, p = 0.025; WOSI change, p = 0.060). Quicker referral to physiotherapy gave improved outcomes (OSIS change, p = 0.004, rs = -0.4; WOSI change, p = 0.047, rs = 0.24). Twenty-one patients (24.7%) were re-referred, seven of them for repeat physiotherapy and 14 of them for surgery. Previous surgery significantly affected the possibility of a further referral (p < 0.001), and initial diagnosis was significantly correlated with further surgery (p = 0.032). DISCUSSION: Early referral to physiotherapy may produce better results. Patients with posterior instability responded better to physiotherapy. Previous surgery increased the risk of re-referral. Re-referred patients with posterior instability tended to be managed with further physiotherapy.

Αbsorbable Plates for Isolated Ulnar Diaphyseal Fractures in Adults - A Case Series Study.

INTRODUCTION: Absorbable materials have been used as fixation devices in orthopaedic surgery. However, their use for treating isolated ulnar diaphyseal fractures in adults has not yet been studied. The aim of this study was to assess whether Inion OTPS™ absorbable implants consisting of L-lactide, D, L-lactide, and trimethylene carbonate provide adequate fixation for the healing of isolated ulnar diaphyseal fractures, their complication rate, and the patients' clinical functional outcome. MATERIALS AND METHODS: Three consecutive patients (all women; mean age, 45 years, and range 38-55 years) with isolated, unstable ulnar fractures were enrolled and treated operatively using Inion OTPS™ absorbable plates and screws. Discontinuation of the study was decided because of the early failure of all implants. The patients were assessed clinically (DASH Score and grip strength) and radiographically at 6 weeks, 3 months, 6 months, and 9 months. The incidence of late foreign body reactions was evaluated for 10 years follow-up period. RESULTS: Implant failure was noticed radiographically in the early post-operative period in all three patients. Subsequently, one patient was treated operatively using metallic devices, and the other two with prolonged splinting. All fractures healed uneventfully in variable time frames. No foreign body reactions were noticed during and beyond the degradation period, other than a small painless mass in one case. CONCLUSION: The results of the current study suggest that the Inion OTPS™ plating system is not appropriate for the fixation of isolated unstable ulnar diaphyseal fractures. It seems that these specific implants cannot withstand the internal mechanical forces of this anatomical area despite the protective splinting.

Suprascapular neuropathy in the setting of rotator cuff tears: study protocol for a double-blinded randomized controlled trial.

BACKGROUND: It has been indicated that rotator cuff tears, especially large or massive ones, can cause suprascapular neuropathy. When such a diagnosis has been established, it is still unknown whether an arthroscopic release of the superior transverse scapular ligament during cuff repair can change the course of this neuropathy. METHODS/DESIGN: This is a single-center, double-blinded randomized controlled trial for which 42 patients with large or massive repairable rotator cuff tears and suprascapular neuropathy will be recruited and followed up at 6 and 12 months. Nerve function will be measured by nerve conduction and electromyography studies preoperatively and at the selected follow-up periods. Patients will be randomly divided into equally numbered groups, the first one being the control group. Patients of this group will undergo arthroscopic repair of the rotator cuff without combined arthroscopic release of the superior transverse scapular ligament; in the second group the ligament will be released. The primary objective is to test the null hypothesis that arthroscopic repair of large/massive rotator cuff tears in patients with combined suprascapular neuropathy provides equivalent outcomes to one-stage arthroscopic cuff repair where the superior suprascapular ligament is additionally released. The secondary objective is to search for a relation between rotator cuff tear size and degree of suprascapular nerve recovery. The tertiary objective is to demonstrate any relation between rotator cuff muscle fatty infiltration grade and degree of suprascapular nerve function. Patients, clinicians during follow-up clinics and the neurologist will be blinded to the type of surgery performed. DISCUSSION: To the best of our knowledge, we are unaware of any prospective, randomized double-blinded studies with similar objectives. So far, the evidence suggests a positive correlation between massive rotator cuff tears and suprascapular neuropathy. However, there is mixed evidence suggesting that neuropathy can be effectively treated with rotator cuff repair with or without release of the superior transverse scapular ligament. TRIAL REGISTRATION: ClinicalTrials.gov registration number NCT02318381 ; date of initial release: 5 December 2014.

The "Pillow" Technique for Thumb Carpometacarpal Joint Arthritis: Cohort Study With 10- to 15-Year Follow-Up.

PURPOSE: Arthritis of the carpometacarpal joint of the thumb is common, and there are many studies regarding its treatment. We investigated the long-term outcome of interposition arthroplasty with a fascia lata allograft (pillow technique), without ligament reconstruction, to treat thumb carpometacarpal arthritis. The technique consisted of complete trapeziectomy, use of alloplastic tensor fascia lata, and K-wire immobilization for 5 weeks. METHODS: The outcomes of 31 thumbs in 24 female patients were measured at a mean follow-up of 12.5 years (range, 10-15 years). RESULTS: Grip strength, key pinch, pulp-to-pulp pinch, tripod pinch, and range of motion were all improved. The Disabilities of the Arm, Shoulder, and Hand median score, which was only measured postoperatively, was an average of 5 (range, 0-52.6). No extrusion of the graft material was noted, and no revisions were performed. CONCLUSIONS: Our results indicate that a fascia lata allograft can be used as an interposition material in thumb carpometacarpal arthroplasty. This technique provides pain relief and satisfactory function at an average of 12.5 years after surgery. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
