Arthroscopy-assisted Minimally Invasive Tarsometatarsal and Lisfranc Arthrodesis. A Case Series.

BACKGROUND: First tarsometatarsal arthrodesis is an effective procedure for the correction of hallux valgus deformities. Traditionally, first to third tarsometatarsal and Lisfranc arthrodesis is performed via an open approach. Little is known about the role of combined arthroscopic and minimally invasive techniques. MATERIAL AND METHODS: We present a case series of complicated hallux valgus deformities and other conditions managed using arthroscopically assisted minimally invasive arthrodesis. We first performed a minimally invasive surgical procedure that allowed easy and unhindered access for the introduction of an arthroscopic instrument over the joint surface. RESULTS: The mean Visual Analogue Score - Foot and Ankle and Short Form-36 scores indicated satisfactory and acceptable postoperative outcomes, respectively. The mean patient satisfaction score was 94.44 and the mean follow-up duration was approximately 17.7 months. CONCLUSION: The described procedure has been preliminarily shown to be useful in terms of its minimal invasiveness, reproducibility, safety, and effectiveness.

A retrospective cohort study: dual cannula combined with modified shoelace continuous capsular closure technique versus nonrepair in hip arthroscopic surgery of femoroacetabular impingement.

BACKGROUND: Over the years, with the improvement of diagnostic and therapeutic capabilities for hip joint diseases and the advancements in surgical technology, hip arthroscopy has been extensively used. At present, there is ongoing controversy among scholars about whether it is necessary to close the joint capsule after hip arthroscopy. In addition, the clinical effect of repairing the hip joint capsule after hip arthroscopy remains uncertain. PURPOSE: To evaluate the effect of our modified shoelace suture technique on postoperative hip function and to investigate whether complete closure of the hip capsule is reliable and safe. STUDY DESIGN: Retrospective study; Levels of evidence: III. METHODS: A retrospective review was conducted on patients undergoing hip arthroscopy by a solitary high-volume hip arthroscopic surgeon. The patients were categorized into two groups. The first group consisted of patients who underwent the modified shoelace continuous capsular closure technique. The other group consisted of those who did not receive capsular closure after hip arthroscopy. Patient-reported outcomes including modified Harris Hip Score (mHHS), Hip Outcome Score of Activities of Daily Living (HOS-ADL), Hip Outcome Score Sport-Specific Subscale (HOS-SSS), and visual analogue scale (VAS) were obtained at a minimum of 12 months. Any complications during follow-up were identified and recorded. RESULTS: A total of 100 patients were followed up for 12-15 months, with an average of (12.3 ± 5.3) months in the study. There were 50 patients in the shoelace capsular closure group (CC group) and 50 patients in the non-capsular closure group (NC group). The surgical time in the suture group was significantly longer than that in the non-suture group. However, there was no statistically significant disparity in the length of hospital stay between the two groups. The mHHS, HOS-SSS, HOS-ADL, and VAS of the CC and NC group were significantly improved compared to preoperative scores at 6 and 12 postoperative months (P < 0.001). Compared with the NC group, the CC group showed a significant improvement in the mHHS, HOS-SSS, HOS-ADL, and VAS at 6 postoperative months (t = 4.885, P<0.001; t = 5.984, P<0.001; t = 4.279, P<0.001; t = 3.875, P<0.001). The mHHS, HOS-SSS, HOS-ADL, and VAS at 12 postoperative months were significantly better in the CC group than in the NC group (t = 5.165, P<0.001; t = 3.697, P<0.001; t = 4.840, P<0.001; t = 3.579, P = 0.001). There were no serious complications during the perioperative period. CONCLUSION: The modified shoelace continuous capsular closure technique is a reliable and secure method that can be used as an alternative to the conventional capsular closure. It is recommended to perform routine intraoperative repair of the articular capsule at the end of hip arthroscopy, as this has a positive influences on the functional results at short-term follow-up.

Analysis of risk factors and construction of nomogram model for arthroscopic single-row rivet repair.

BACKGROUND: The factors influencing the clinical outcome of arthroscopic rotator cuff repair are not fully understood. PURPOSE: To explore the factors related to the postoperative outcome of arthroscopic single-row rivet rotator cuff repair in patients with rotator cuff injury and to construct the related nomogram risk prediction model. METHODS: 207 patients with rotator cuff injury who underwent arthroscopic single-row rivet rotator cuff repair were reviewed. The differences of preoperative and postoperative Visual Analogue Score (VAS) scores and University of California, Los Angeles (UCLA) scores were analyzed and compared. The postoperative UCLA score of 29 points was taken as the critical point, and the patients were divided into good recovery group and poor recovery group, and binary logstic regression analysis was performed. According to the results of multivariate logistic regression analysis, the correlation nomogram model was constructed, and the calibration chart was used, AUC, C-index. The accuracy, discrimination and clinical value of the prediction model were evaluated by decision curve analysis. Finally, internal validation is performed using self-random sampling. RESULTS: The mean follow-up time was 29.92 ± 17.20 months. There were significant differences in VAS score and UCLA score between preoperative and final follow-up (p < 0.05); multivariate regression analysis showed: Combined frozen shoulder (OR = 3.890, 95% CI: 1.544 ∼ 9.800), massive rotator cuff tear (OR = 3.809, 95%CI: 1.218 ∼ 11.908), More rivets number (OR = 2.118, 95%CI: 1.386 ∼ 3.237), lower preoperative UCLA score (OR = 0.831, 95%CI: 0.704-0.981) were adverse factors for the postoperative effect of arthroscopic rotator cuff repair. Use these factors to build a nomogram. The nomogram showed good discriminant and predictive power, with AUC of 0.849 and C-index of 0.900 (95% CI: 0.845 ∼ 0.955), and the corrected C index was as high as 0.836 in internal validation. Decision curve analysis also showed that the nomogram could be used clinically when intervention was performed at a threshold of 2%∼91%. CONCLUSION: Combined frozen shoulders, massive rotator cuff tears, and increased number of rivets during surgery were all factors associated with poor outcome after arthroscopic rotator cuff repair, while higher preoperative UCLA scores were factors associated with good outcome after arthroscopic rotator cuff repair. This study provides clinicians with a new and relatively accurate nomogram model.

Arthroscopic shoulder surgery for gouty long head of biceps tendinitis: a case report.

OBJECTIVE: The objective of the case report is to analyze the clinical manifestations and imaging features of gouty long head of biceps tendinitis, and to summarize the methods and effects of shoulder arthroscopic surgery. CLINICAL PRESENTATION AND INTERVENTION: The clinical data of a 39-year-old Han Chinese female with gouty long head of the biceps tendinitis was retrospectively analyzed, and the clinical manifestations, imaging features, and diagnosis and treatment were analyzed. The patient presented with pain and limited movement of right shoulder joint. Computed tomography showed irregular high-density shadows above the glenoid and adjacent to the coracoid process of the right shoulder. Magnetic resonance imaging revealed superior labrum anterior and posterior injury with edema in the upper recess and axillary sac. After arthroscopic surgery, the "tofu residue" tissue of the long head of the biceps was removed, and the postoperative pathological examination proved that it was gout stone. CONCLUSION: Gouty long head of the biceps tendinitis is a rare disease. Arthroscopic surgery can probe the structural lesions of shoulder cavity in all aspects, improve the surgical accuracy, and reduce the trauma.

Partial excision of infrapatellar fat pad for the treatment of knee osteoarthritis.

AIMS: Knee osteoarthritis (KOA) is a common degenerative joint disease characterized by pain and functional limitations. Current treatments offer symptomatic relief but do not address the underlying pathology. This study explores the role of the infrapatellar fat pad (IFP) in KOA and evaluates the efficacy of its partial arthroscopic excision. METHODS: A retrospective review was conducted on 37 KOA patients who underwent partial IFP excision. Pain and function were assessed using the WOMAC and VAS scores, while MRI evaluations focused on cartilage health. RESULTS: Significant postoperative improvements were observed in both pain and functional outcomes, with substantial reductions in WOMAC and VAS scores (P < 0.001). MRI findings demonstrated notable enhancements in cartilage integrity, reflected in significantly improved WORMS scores (P < 0.001). CONCLUSIONS: Partial excision of the IFP significantly reduces pain and improves function in KOA patients, while also promoting cartilage health. These findings support the IFP's role in KOA pathology and highlight the potential benefits of targeted surgical intervention.

Innovative Percutaneous Quadricepsplasty for Knee Extension Contracture in Arthrogryposis: A Case Report.

CASE: A 15-year-old male patient diagnosed with arthrogryposis presented with a left knee extension contracture. He underwent an innovative percutaneous quadricepsplasty performed arthroscopically. Subsequent to the procedure, the patient was enrolled in an aggressive physiotherapy program. Over a follow-up period of 12 months, significant improvement was observed, with the patient achieving a 95° range of motion in his left knee. CONCLUSION: Noninvasive percutaneous quadricepsplasty, combined with methods such as arthroscopy, may enhance therapeutic outcomes and alleviate chronic knee extension contractures in patients with arthrogryposis. This combination of treatment methods has the potential to revolutionize the management of such conditions.

Controversies in surgical management of anterior shoulder instability. State of the Art.

Arthroscopic Bankart repair (ABR) has been accepted as a standard procedure for anterior shoulder instability with a minimum or no glenoid bone loss and an on-track Hill-Sachs lesion if present. However, several controversies exist in the surgical treatment of anterior shoulder instability. This article will discuss some of these controversies in, "simple," dislocations (without bone loss) as well as, "complex," (with critical bone loss). Determining which patients will benefit from an arthroscopic procedure depends on multiple factors including age, activity level, adequate determination of bone loss, performed with feasible and reliable imaging techniques. In the absence of concomitant significant bony and soft tissue pathology, ABR alone can provide satisfactory clinical results on a long-term basis. Controversies, including whether to remove cartilage from the edge of the glenoid, knotted versus knotless anchors, and routine rotator interval closure, still exist. In cases with significant bone loss, several bone restoring procedures have been described, such as, the Latarjet procedure, iliac crest bone graft, arthroscopic anatomic glenoid reconstruction with a frozen distal tibial allograft, and fresh distal tibial allograft reconstruction. This article will address these controversies and provide guidance based on available published data.

Arthroscopic procedures for degenerative rotator cuff disease: a systematic review and network meta-analysis.

BACKGROUND: Treatment of rotator cuff diseases often involves various arthroscopic procedures but their combined effectiveness remains contentious, especially in complex cases. METHODS: We focused on patients with degenerative shoulder cuff diseases requiring arthroscopic rotator cuff repair. Searches covered multiple databases (Medline, Embase, Web of Science, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and Cochrane Clinical Answers) up to April 1, 2024. Bias risk was assessed using RevMan (v 5.4), and a network meta-analysis was conducted with netmeta (v 2.8). RESULT: From 16 studies, 1232 patients (average age, 56.2 years; balanced sex ratio) were included. Arthroscopic rotator cuff repair ranked highest in functional score networks, surpassing other interventions. Physiotherapy was superior for pain relief compared to arthroscopic procedures combined with platelet-rich plasma (mean, 2.5; 95% confidence interval, 4.48-0.52). Arthroscopic rotator cuff repair and subacromial decompression were significantly superior to arthroscopic rotator cuff repair and subacromial decompression combined with platelet-rich plasma (MD, 1.80; 95% CI, 3.39-0.21). DISCUSSION: Moderate bias risks were noted in both networks due to blinding issues and methodological quality reporting. Arthroscopic rotator cuff repair is favored for improving shoulder function, while other procedures or intra-articular treatments offer no significant benefits. Regarding pain management, physiotherapy is preferred; however, more evidence is needed to support this recommendation and caution is advised.

Comparative analysis of functional outcomes in arthroscopic repair for traumatic and non-traumatic rotator cuff injuries.

BACKGROUND: The impact of the etiology of rotator cuff injury (RCI) on outcomes after rotator cuff repair remains unclear. This study aimed to evaluate the postoperative outcomes of patients with RCIs of different etiologies and identify the risk factors affecting prognosis. METHODS: This study included 73 patients with RCI who underwent arthroscopic rotator cuff repair. The patients were categorized into either a traumatic group or a non-traumatic group based on their history of trauma. Preoperative and postoperative assessments included shoulder range of motion, muscle strength, and physical examination findings specific to the shoulder for both groups. Clinical differences between arthroscopic repair of traumatic and non-traumatic RCIs were evaluated using univariate analysis. Logistic regression analysis determined independent risk factors for rotator cuff repair prognosis. RESULTS: Among the 73 patients, 31 were in the traumatic group and 42 in the non-traumatic group, with a minimum postoperative follow-up of 12 months and a mean follow-up of 13.8 months. The duration of the disease was significantly longer in the non-traumatic group compared with the traumatic group (P < 0.001). The mean tear area was more significant in the traumatic group than in the non-traumatic group (P = 0.003), and the preoperative pain level and functional scores were better in the non-traumatic group compared with the traumatic group. Postoperatively, there were no differences between the two groups regarding scores, joint mobility, strength, and complications. At 12 months postoperatively, multivariate regression analysis indicated that full-layer tear (OR = 5.106, 95% CI: 1.137-22.927, P = 0.033), fat infiltration (OR = 6.020, 95% CI: 1.113-32.554, P = 0.037), and tear area (OR = 6.038, 95% CI: 2.122-17.177, P < 0.001) significantly affected the University of California at Los Angeles (UCLA) score. CONCLUSION: Compared with non-traumatic RCI, traumatic RCI presents with more pronounced pain and impaired joint function preoperatively yet demonstrates comparable postoperative clinical outcomes. Full-layer tears, fat infiltration, and large tear areas are unfavorable factors affecting rotator cuff repair, and postoperative rehabilitation management of these patients should be emphasized.

Comparison of clinical outcomes and repair integrity after arthroscopic versus mini-open rotator cuff repair: An observational study.

This study aimed to evaluate the differences between mini-open (MO) and arthroscopic (ART) repair procedures for rotator cuff tendon tears in terms of clinical and radiological outcomes. This retrospective study included 59 patients, and data were collected prospectively. Patients with full-thickness rotator cuff tears were randomized to undergo MO or ART repair at 2 centers by 2 surgeons between January 2012 and December 2017. Data were collected 3 weeks before surgery and 6 and 12 months after surgery. Physical function was assessed using the American Shoulder and Elbow Surgeons index, VAS, and Constant scoring system. Radiological outcomes were assessed using the Sugaya classification, adapted for ultrasound. Changes between baseline and follow-up were compared between the 2 groups. Fifty-nine patients who underwent ART or MO rotator cuff repair were included in this study. The 2 groups had similar demographic characteristics and preoperative baseline parameters. Both the MO and ART groups showed statistically significant improvement in outcome parameters (P ≤ .0001); however, cuff repair integrity was significantly better in the ART group (P = .023). All other improvements in the patient-derived parameters were equivalent. None of the patients in either group required revision surgery. According to the results of our retrospective study, MO and ART rotator cuff repair are effective and viable options for surgeons to repair rotator cuff tears. There were no differences in objective and subjective outcomes between the full ART and MO techniques for rotator cuff tears. Surgeons should choose a technique with which they are more familiar.

Effect of low-volume ropivacaine in ultrasound-guided superior trunk block on diaphragmatic movement in patients undergoing shoulder arthroscopy: a randomized controlled trial.

OBJECTIVES: The incidence of hemidiaphragmatic paresis (HDP) in superior trunk block (STB) usually depends on the dose of local anesthetic. This study aimed to further evaluate the impact of a lower volume (10 mL) of the same low concentration (0.25%) ropivacaine compared to a conventional volume (15 mL), on diaphragmatic function and analgesic efficacy under a multimodal analgesia regimen for shoulder arthroscopy. METHODS: Patients scheduled to undergo shoulder arthroscopy were randomized allocated to receive either 10 mL or 15 mL of 0.25% ropivacaine in the STB under ultrasound guidance prior to general anesthesia. The primary outcome was the percentage reduction in diaphragm excursion (ΔDE) between baseline and 30 min after block. Secondary outcomes included DE and diaphragm thickening fraction (DTF) before and after block, incidence of HDP, onset of sensory/motor block, duration of analgesia/motor block, dermatomal coverage area of the block, postoperative pain severity, pre- and post-block respiratory function and intraoperative hemodynamic parameters, the use of other anesthetic and analgesic drugs, post-block complications, and adverse events post-surgery. RESULTS: Compared with 15 mL volume, 10 mL ropivacaine significantly reduced the incidence of post-block HDP (as measured by ΔDE: 39.47% vs. 64.10%; and by post-block DTF: 13.16% vs. 33.33%). There was no significant difference in onset of sensory block, duration of analgesia/motor block, dermatomal coverage area of the block, postoperative pain severity between the two groups, except that the onset of motor block was significantly slower in the 10 mL group than in the 15 mL group. Pre- and post-block respiratory function and intraoperative hemodynamic parameters, the use of other anesthetic and analgesic drugs, post-block complications, or postoperative adverse events were not significantly different between the two groups. CONCLUSION: In shoulder arthroscopy, STB with 10 mL of ropivacaine can reduce the incidence of HDP with no significant difference in analgesic effects under a multimodal analgesia regimen compared with 15 mL.

Arthroscopic Management of Moderate-to-Severe Osteoarthritis of the Knee: A Systematic Review.

BACKGROUND: Total knee arthroplasty (TKA) is the procedure of choice for osteoarthritis of the knee (OAK) when conservative treatment fails; however, high rates of dissatisfaction and poor implant longevity dissuade younger patients from TKA. There is a paucity of evidence that report outcomes and clinical effectiveness of arthroscopic knee procedures in patients with end-stage (grade 3-4) OAK. The purpose of this systematic review was to evaluate the efficacy of arthroscopic treatment for patients with moderate-to-severe (grade 3-4) OAK. METHODS: A systematic review of the literature was performed with the terms "Knee," "Osteoarthritis," and/or "Arthroscopic debridement," "Arthroscopic lavage," "Arthroscopic microfracture," "Arthroscopic chondroplasty," "debridement," "lavage," "chondroplasty," "microfracture," and/or "arthroscopy" in PubMed (MEDLINE), Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) databases in November 2023 according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Databases were searched for studies that evaluated outcomes (e.g., pain, function, and conversion to TKA) for patients with Kellgren-Lawrence grade 3 to 4 OAK after knee arthroscopy (including debridement, lavage, microfracture, or chondroplasty) at a minimum 6-month follow-up. Percent improvement from preoperative score was the primary outcome measure. Secondary outcome measures included achievement of minimal clinically importance difference and conversion to TKA. RESULTS: Nine studies (410 knees with grades 3-4 OAK) were included. Arthroscopic debridement and lavage resulted in a 18.8% to 53.1% improvement at short-term follow-up (e.g., 6 months to 3 years) and a 50.0% improvement at long-term follow-up (e.g., 10 years) in knees with grade 3 OAK and a 15.0% to 41.3% improvement at short-term follow-up and a 46.9% improvement at long-term follow-up in knees with grade 4 OAK. Arthroscopic debridement and microfracture resulted in 1.6% to 50.8% improvement at short-term follow-up in knees with grade 3 OAK. No studies included long-term outcomes or evaluated knees with grade 4 OAK after arthroscopic debridement and microfracture. Conversion to TKA after arthroscopic debridement and lavage occurred in 21.9% of patients with grade 3 OAK and in 35.0% of patients with grade 4 OAK at short-term follow-up and in 47.4% of patients with grade 3 OAK and in 76.5% of patients with grade 4 OAK at long-term follow-up. Conversion to TKA after arthroscopic debridement and microfracture occurred in 10.9% of patients with grade 3 and 4 OAK at long-term follow-up. CONCLUSION: Arthroscopic debridement, lavage, and microfracture can provide short- and long-term symptomatic relief and improvement in function by up to 50.0% in patients with grade 3 to 4 OAK. These procedures may result in fewer patients with grade 3 OAK undergoing TKA compared with patients with grade 4 OAK. LEVEL OF EVIDENCE: Level IV; systematic review of Level II-IV studies.

Comparison of Arthroscopic Microfracture and Retrograde Subchondral Drilling in the Treatment of Osteochondral Lesions of Talus.

PURPOSE OF THE STUDY: In our study, it was aimed to evaluate the efficacy of microfracture and retrograde subchondral drilling on clinical outcomes in patients who underwent ankle arthroscopy due to osteochondral lesion of medial talus. MATERIAL AND METHODS: Twenty eight patients with osteochondral lesion of talus less than 1.5 cm2 treated with ankle arthroscopy were evaluated retrospectively. Microfracture was performed in 16 patients and retrograde subchondral drilling was performed in 12 patients that there was no loss of integrity in the cartilage layer or cartilage layer is partially preserved during ankle arthroscopy. Postoperative evaluations of the patients were done with Foot and Ankle Ability Measure (FAAM) and results of both group were compared statistically. RESULTS: The mean activities of daily living scale was 93.4±3.2 and sportive activity scale was 90.1±5.7 in the retrograde drilling group. In the micro-fracture group, mean activities of daily living scale was 93.8±4.1 and mean sportive activity scale was 88.9±9.5. No significant difference was found as a result of statistical comparisons of both groups results. DISCUSSION: It has been determined that the size and preservation of the integrity of talar osteochondral lesions are important factors on clinical results. Results of arthroscopic debridement, microfracture and drilization are not good in lesions larger than 1.5 cm2 and lesions with impaired integrity. In our study, depending on the general literature, osteochondral lesions in talus were less than 1.5 cm2 in patients who underwent arthroscopic micro fracture and retrograde drilling. CONCLUSIONS: Both microfracture and retrograde subchondral drilling are effective treatment methods with good clinical results for talar osteochondral lesions less than 1,5cm2 . Retrograde subchondral drilling can be an alternative treatment method with the reliability of clinical results in patients with no loss of the integrity of the cartilage layer or cartilage layer is partially preserved. KEY WORDS: talus, osteochondral lesion, microfracture, subchondral drilling.

[Treatment of massive rotator cuff tears with modified Chinese-way technique].

OBJECTIVE: To explore clinical effect of modified Chinese-way technique under shoulder arthroscopy in treating massive rotator cuff tears. METHODS: From January 2019 to June 2022, 22 patients with massive rotator cuff tears who underwent arthroscopic rotator cuff repair with improved Chinese-way technique, including 10 males and 12 females, aged from 46 to 76 years old with an average of(64.14±7.45) years old;the courses of disease ranged from 5 to 14 months with an average of(8.32±2.42) months;19 patients were complete repaired, and 3 patients were partial repaired. Visual analogue scale (VAS) and University of California at Los Angeles (UCLA) scale were used to evaluate pain and function of shoulder joint preoperatively and 1 year postoperatively. Postoperative complications, the integrity of reconstructed tissue structure and the size of subacromial space were observed. RESULTS: All patients were followed up from 12 to 34 months with an average of (17.14±5.93) months. Re-tear were occurred in 4 patients during MRI follow-up, but clinical symptoms of patients were improved significantly and they were satisfied with the treatment, the others were no complications such as incision infection, peripheral nerve injury, loosening and falling off of internal fixation anchors. Preoperative and 1 year after operation VAS were (8.05±1.12) and (1.82±1.50), UCLA scores were (7.45±1.65) and (31.41±2.87) respectively, and the difference was statistically significant (P<0.05). CONCLUSION: The modified Chinese-way technique under shoulder arthroscopy for the massive rotator cuff tear could relieve pain obviously and recovery postoperative function well, with satisfactory curative effect.

Clinical comprehensive of microfracture, autologous chondrocyte implantation, and periosteum-covered iliac bone grafting for Hepple stage IV-V lesions.

Chronic ankle pain significantly impairs daily activities and athletic performance with osteochondral lesions of the talus (OLT) in Hepple stages IV and V, which are often causative factors. This study aimed to assess the efficacy and safety of autologous osteochondral transplantation (AOT) for the treatment of these conditions. This retrospective study was conducted from May 2020 to May 2023 at Cangzhou Traditional Chinese and Western Medicine Combined Hospital, including patients with a diagnosis of Hepple stage IV or V OLT confirmed by magnetic resonance imaging (MRI) and arthroscopy. Surgical interventions involved arthroscopic debridement, followed by AOT or limited arthrotomy based on the location and size of the lesion. Preoperative and postoperative evaluations used the Visual Analog Scale, American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale, MRI-Based Cartilage Repair Tissue Scoring, and the International Knee Documentation Committee Knee Evaluation Form. Statistical analysis was conducted using paired-sample t tests to compare the preoperative and postoperative data. Twenty patients were included, revealing significant postoperative improvements in Visual Analog Scale, American Orthopedic Foot and Ankle Society, and MRI-based cartilage repair tissue scores (P < .05). The radiographic findings suggested effective cartilage regeneration. No adverse effects were observed in the donor knee sites, as confirmed by the stable pre- and postoperative International Knee Documentation Committee Knee Evaluation Form scores. Recovery of physical abilities was achieved on average within 7.3 weeks for daily activities and 13.4 weeks for sports activities. AOT effectively treats Hepple stage IV-V OLT, improves ankle function, promotes cartilage regrowth, and allows quick resumption of daily and athletic activities without compromising donor-site integrity.

Functional benefit of joint surgery in patients with non-vascular Ehlers-Danlos syndrome: results of a retrospective study.

BACKGROUND: Ehlers-Danlos syndrome (EDS) is a hereditary disease characterised by joint hypermobility, skin hyperextensibility and tissue fragility. Hypermobile EDS (hEDS is the more frequent subtype. Joint surgery may benefit certain patients after failure of medical treatments, but there is no consensus on the optimal surgical management of patients with hEDS. The aims of this retrospective study were to chart the surgical management of patients with hEDS, to determine the role of arthroscopy and to evaluate the functional results of joint surgery, including the reintervention rates. RESULTS: A total of 69 patients with non-vascular EDS were evaluated (60 female; 87%). Mean (SD) age at first surgery was 25.6 ± 11.1 years. Among the 69 patients, first surgeries were carried out on the knee (n = 50; 39.4%), ankle (n = 28; 22.0%), shoulder (n = 22; 17.3%), wrist (n = 18; 14.2%) and elbow (n = 9; 7.1%). One-fifth of all first operations (20.8%) were carried out by arthroscopy, most often on the knee (36% of knee surgery cases). At the time of primary surgery, the surgeon was alerted to the diagnosis or suspicion of hEDS in only 33.9% of patients. The rate of reoperations (2 to ≥ 5) was 35.7% (10/28) for the ankle, 40.9% (9/22) for the shoulder, 44.4% (4/9) for the elbow, 50% (9/18) for the wrist and 60% (30/50) for the knee. Local or regional anaesthesia was badly tolerated or ineffective in 27.8%, 36.4% and 66.6% of operations on the wrist, shoulder and elbow, respectively. Overall, the majority of patients (> 70%) were satisfied or very satisfied with their surgery, particularly on the non-dominant side. The lowest satisfaction rate was for shoulder surgery on the dominant side (58.3% dissatisfied). CONCLUSIONS: Surgery for joint instability has a greater chance of success when it is carried out in patients with a known diagnosis of EDS before surgery. The majority of patients were satisfied with their surgery and, with the exception of the knee, there was a low rate of reoperations (≤ 50%). Arthroscopic procedures have an important role to play in these patients, particularly when surgery is performed on the knee.

Extra-Articular Abscess Expansion as a Specific Complication of Septic Arthritis of the Shoulder Joint: Report of Three Cases with Extension of the Infection through the Biceps Groove Producing a Large Abscess.

BACKGROUND: Septic arthritis of shoulder is a rare clinical entity as the metaphysis is extracapsular and there is no communication between epiphyseal and metaphyseal vessels. Septic arthritis of the shoulder joint is a diagnostic and surgical emergency because joint destruction develops rapidly and can cause significant morbidity and mortality. Unusual complications of septic arthritis of the shoulder joint may include extra-articular abscess extension to the upper arm through the biceps groove and osteomyelitis of the greater tuberosity. CASE PRESENTATION: Septic arthritis of the shoulder, if left untreated, can lead to complications such as extra-articular abscess extension and osteomyelitis. Three patients with septic arthritis of the shoulder joint with no clear history of trauma were reported in this study. The initial presentation was pseudoparalysis with upper arm swelling. MRI diagnosed septic arthritis of shoulder joint together with an upper arm abscess. Arthroscopic debridement with through irrigation and open drainage of the extra-articular abscess extension to the upper arm improved both the shoulder pain and abscess completely. However, if shoulder pain or abnormalities in laboratory findings continue after initial treatment, uncontrolled septic arthritis or secondary osteomyelitis are possibilities that should be concerned. MRI is a useful tool for detecting those atypical complications. CONCLUSIONS: Rarely, septic arthritis of the shoulder joint can extend to the upper arm through the biceps tendon groove and cause an abscess. Also, acute osteomyelitis of the tuberosity should be considered in patients with long-standing refractory septic arthritis of the shoulder joint who have continued pain and uncontrolled laboratory findings after initial treatment.

Arthroscopic-assisted uni-portal ligament flavum sparing bone anchoring annular suture technique for lumbar disc herniation: A case report and literature review.

RATIONALE: Lumbar disc herniation (LDH) manifests in diverse forms. If the nucleus pulposus or endplate tissues protrudes, the location of annular tears also varies, which poses various challenges for the annular suture technique. Tears at the annular attachment area at the edge of the vertebral body (cephalad or caudad) are considered a prohibitively challenging area for annular suturing. PATIENT CONCERNS: A 37-year-old woman presented with a gradual onset of symptoms, experiencing leg pain and numbness over the left leg for 1 year before presentation. The pain radiated to the left S1 dermatome. Despite undergoing continuous medical therapy for more than 6 months, her symptoms showed no improvement. The strength of the left plantar flexion in the ankle and great toe was rated at 4 out of 5. The straight leg-raising and strengthening tests were positive for the left sides. Lumbar computed tomography and magnetic resonance imaging revealed left-sided disc herniation at the L5-S1 level, and nerve root compression, confirming the diagnosis of LDH. DIAGNOSES: The preoperative impression was LDH, intraoperative confirmation of a tear in the annular attachment area at the vertebral body edge. INTERVENTIONS: This patient was treated with an arthroscopic-assisted uniportal spinal surgery (AUSS) technique focusing on ligament flavum (LF) preservation, protruding nucleus pulposus removal, nerve root decompression, and vertebral edge tear was then sutured using a bone anchoring annular suture with the Smile suture device. OUTCOMES: This technique was performed successfully in a patient with LDH. Significant improvements were observed in postoperative pain and numbness, Visual Analog Scale, and Japanese Orthopaedic Association scores. No postoperative instability or complications were observed, with computed tomography and magnetic resonance imaging confirming complete decompression. To the best of our knowledge, this is the first used AUSS with LF preservation and bone anchoring annular suture technique for LDH. LESSONS: This case study demonstrates the AUSS combined with LF preservation and the bone anchoring annular suture technique provides favorable clinical and imaging outcomes and is a safe and effective technique for the treatment of LDH.

Management of bone loss in anterior shoulder instability.

Bone defects are frequently observed in anterior shoulder instability. Over the last decade, knowledge of the association of bone loss with increased failure rates of soft-tissue repair has shifted the surgical management of chronic shoulder instability. On the glenoid side, there is no controversy about the critical glenoid bone loss being 20%. However, poor outcomes have been described even with a subcritical glenoid bone defect as low as 13.5%. On the humeral side, the Hill-Sachs lesion should be evaluated concomitantly with the glenoid defect as the two sides of the same bipolar lesion which interact in the instability process, as described by the glenoid track concept. We advocate adding remplissage to every Bankart repair in patients with a Hill-Sachs lesion, regardless of the glenoid bone loss. When critical or subcritical glenoid bone loss occurs in active patients (> 15%) or bipolar off-track lesions, we should consider anterior glenoid bone reconstructions. The techniques have evolved significantly over the last two decades, moving from open procedures to arthroscopic, and from screw fixation to metal-free fixation. The new arthroscopic techniques of glenoid bone reconstruction procedures allow precise positioning of the graft, identification, and treatment of concomitant injuries with low morbidity and faster recovery. Given the problems associated with bone resorption and metal hardware protrusion, the new metal-free techniques for Latarjet or free bone block procedures seem a good solution to avoid these complications, although no long-term data are yet available.

Outcomes of arthroscopic stabilization for recurrent instability are equal to stabilization after a primary event.

Aims: Extensive literature exists relating to the management of shoulder instability, with a more recent focus on glenoid and humeral bone loss. However, the optimal timing for surgery following a dislocation remains unclear. There is concern that recurrent dislocations may worsen subsequent surgical outcomes, with some advocating stabilization after the first dislocation. The aim of this study was to determine if the recurrence of instability following arthroscopic stabilization in patients without significant glenoid bone loss was influenced by the number of dislocations prior to surgery. Methods: A systematic review and meta-analysis was performed using the PubMed, EMBASE, Orthosearch, and Cochrane databases with the following search terms: ((shoulder or glenohumeral) and (dislocation or subluxation) and arthroscopic and (Bankart or stabilisation or stabilization) and (redislocation or re-dislocation or recurrence or instability)). Methodology followed the PRISMA guidelines. Data and outcomes were synthesized by two independent reviewers, and papers were assessed for bias and quality. Results: Overall, 35 studies including 7,995 shoulders were eligible for analysis, with a mean follow-up of 32.7 months (12 to 159.5). The rate of post-stabilization instability was 9.8% in first-time dislocators, 9.1% in recurrent dislocators, and 8.5% in a mixed cohort. A descriptive analysis investigated the influence of recurrent instability or age in the risk of instability post-stabilization, with an association seen with increasing age and a reduced risk of recurrence post-stabilization. Conclusion: Using modern arthroscopic techniques, patients sustaining an anterior shoulder dislocation without glenoid bone loss can expect a low risk of recurrence postoperatively, and no significant difference was found between first-time and recurrent dislocators. Furthermore, high-risk cohorts can expect a low, albeit slightly higher, rate of redislocation. With the findings of this study, patients and clinicians can be more informed as to the likely outcomes of arthroscopic stabilization within this patient subset.
