In-Office Needle Arthroscopy for Superior Labral Tear Debridement.

SLAP tears are a common cause of shoulder pain in overhead athletes. The benefits of in-office nano-arthroscopy include the ability to diagnosis and treat biceps tendinopathy, quicker patient recovery, reduced health care costs, and improved patient satisfaction. This technique can be particularly advantageous in the management of SLAP tears given that magnetic resonance imaging has poor sensitivity without the use of an invasive arthrogram. The purpose of this technical report is to describe our technique for performing in-office nano-arthroscopy for SLAP tears with special consideration of the technique for obtaining adequate local anesthesia, proper indications, and adequate visualization, as well as the advantages of performing these procedures in the office rather than the operating room.

Tranexamic acid reduces perioperative blood loss and postoperative hemoglobin loss during total ankle arthroplasty: A systematic review and meta-analysis of clinical comparative studies.

IMPORTANCE: Peri-operative blood loss during joint replacement procedures is a modifiable risk factor that impacts wound complications, hospital stay and total costs. Tranexamic acid (TXA) is an anti-fibrinolytic that has been widely used in orthopedic surgery, but its efficacy in the setting of total ankle arthroplasty (TAA) has not been quantified to date. AIM: The purpose of this systematic review and meta-analysis was to evaluate the efficacy and safety of administering TXA in patients undergoing TAA. EVIDENCE REVIEW: The Medline, Embase and Cochrane library databases were systematically reviewed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Five comparative studies examining blood loss following administration of TXA for patients undergoing TAA were included. The outcome measures of interest were blood loss, reduction in hemoglobin concentration, transfusion requirements, total complications and wound complications. FINDINGS: In total, 194 patients received TXA and 187 patients did not receive TXA while undergoing TAA. Based on the common-effects model for total blood loss for the TXA group versus control, the standardized mean difference (SMD) was -0.7832 (95% CI, -1.1544, -0.4120; P â€‹< â€‹0.0001), in favor of lower total blood loss for TXA. Based on the random-effects model for reduction in hemoglobin for the TXA group versus control, the SMD was -0.9548 (95% CI, -1.7850, -0.1246; P â€‹= â€‹0.0242) in favor of lower hemoglobin loss for TXA. Based on the random-effects model for total complications for the TXA group versus control, the risk ratio was 0.512 (95% CI, 0.1588, 1.6512; P â€‹= â€‹0.1876), in favor of lower total complications for TXA but this was not statistically significant. CONCLUSIONS: This current review demonstrated that administration of TXA led to a reduction in blood loss and hemoglobin loss without an increased risk of the development of venous thromboembolism in patients undergoing TAA. No difference was observed with respect to total complication rates between the TXA cohort and the control group. TXA appears to be an effective hemostatic agent in the setting of TAA, but further studies are necessary to identify the optimal timing, dosage and route of TXA during TAA. LEVEL OF EVIDENCE: III.

The significance of heterotopic ossification following total ankle arthroplasty: a systematic review and meta-analysis.

PURPOSE: The purpose of this systematic review and meta-analysis was to evaluate the prevalence and clinical significance of heterotopic ossification (HO) following total ankle replacement (TAR). METHODS: During August 2023, the PubMed, Embase and Cochrane library databases were systematically reviewed to identify clinical studies reporting HO following TAR. Data regarding surgical characteristics, pathological characteristics, subjective clinical outcomes, ankle range of motion, radiographic outcomes, reoperation rates were extracted and analysed. RESULTS: Twenty-seven studies with 2639 patients (2695 ankles) at a weighed mean follow-up time of 52.8 ± 26.9 months were included. The pooled prevalence rate was 44.6% (0.25; 0.66). The implant with the highest rate of HO was the INBONE I (100%) and BOX (100%) implants. The most common modified Brooker staging was grade 1 (132 patients, 27.0%). Random effects models of standardized mean differences found no difference in American orthopedic foot and ankle society (AOFAS) scores, visual analog scale scores (VAS) and ankle range of motion (ROM) between patients with HO and patients without HO. Random effects models of correlation coefficients found no correlation between AOFAS, VAS and ROM and the presence of HO. The surgical intervention rate for symptomatic HO was 4.2%. CONCLUSION: This systematic review and meta-analysis found that HO is a common finding following TAR that is not associated with inferior clinical outcomes. Surgical intervention was required only for moderate-to-severe, symptomatic HO following TAR. This study is limited by the marked heterogeneity and low level and quality of evidence of the included studies. Further higher quality studies are warranted to determine the precise prevalence and impact of HO on outcomes following TAR.

Polyvinyl alcohol hydrogel implant for the treatment of hallux rigidus is associated with a high complication rate and moderate failure rate at short-term follow-up: a systematic review.

PURPOSE: Moderate-to-severe hallux rigidus is a debilitating pathology that is optimally treated with surgical intervention. Arthrodesis produces reliable clinical outcomes but is limited by restriction in 1st metatarsophalangeal joint range of motion. The advent of polyvinyl alcohol hydrogel (PVA) implants have produced early promise based on initial trials, but more recent studies have called into question the efficacy of this procedure. The purpose of this systematic review was to evaluate the clinical and radiological outcomes following the use of PVA for hallux rigidus. METHODS: The MEDLINE, EMBASE and Cochrane library databases were systematically reviewed using the preferred reporting items for systematic reviews and meta-analyses guidelines. 18 studies were included. RESULTS: In total, 1349 patients (1367 feet) underwent PVA at a weighted mean follow-up of 24.1 ± 11.1 months. There were 168 patients (169 feet) included in the cheilectomy cohort and 322 patients (322 feet) included in the arthrodesis cohort. All 3 cohorts produced comparable improvements in subjective clinical outcomes. Postoperative imaging findings in the PVA cohort included joint space narrowing, peri-implant fluid, peri-implant edema and erosion of the proximal phalanx. The complication rate in the PVA cohort, cheilectomy cohort and arthrodesis cohort was 27.9%, 11.8% and 24.1%, respectively. The failure rates in the PVA cohort, cheilectomy cohort and arthrodesis cohort was 14.8%, 0.3% and 9.0%, respectively. CONCLUSION: This systematic review demonstrated that PVA produced a high complication rate (27.9%) together with concerning postoperative imaging findings at short-term follow-up. In addition, a moderate failure rate (14.8%) and secondary surgical procedure rate (9.5%) was noted for the PVA cohort. The findings of this review calls into question the efficacy and safety of PVA for the treatment of hallux rigidus. LEVEL OF EVIDENCE: IV.

Particulated juvenile cartilage allograft for the treatment of osteochondral lesions of the talus is associated with a high complication rate and a high failure rate at short-term follow-up: A systematic review.

PURPOSE: The purpose of this systematic review was to evaluate the clinical and radiological outcomes together with the complication rates and failure rates at short-term follow-up following particulated juvenile cartilage allograft (PJCA) for the management of osteochondral lesions of the talus (OLT). METHODS: During October 2023, the PubMed, Embase and Cochrane library databases were systematically reviewed to identify clinical studies examining outcomes following PJCA for the management of OLTs. Data regarding study characteristics, patient demographics, lesion characteristics, subjective clinical outcomes, radiological outcomes, complications and failures were extracted and analysed. RESULTS: Twelve studies were included. In total, 241 patients underwent PJCA for the treatment of OLT at a weighted mean follow-up of 29.0 ± 24.9 months. The weighted mean lesion size was 138.3 ± 59.6 mm2 . Prior surgical intervention was recorded in seven studies, the most common of which was microfracture (65.9%). The weighted mean American Orthopaedic Foot and Ankle Society score improved from a preoperative score of 58.5 ± 3.2 to a postoperative score of 83.9 ± 5.3. The weighted mean postoperative magnetic resonance observation of cartilage repair tissue (MOCART) score was 48.2 ± 3.3. The complication rate was 25.2%, the most common of which was allograft hypertrophy (13.2%). Thirty failures (12.4%) were observed at a weighted mean time of 9.8 ± 9.6 months following the index procedure. CONCLUSION: This systematic review demonstrated a moderate improvement in subjective clinical outcomes following PJCA for the treatment of OLT at short term follow-up. However, postoperative MOCART scores were reported as poor. In addition, a high complication rate (25.2%) and a high failure rate (12.4%) at short-term follow-up was observed, calling into question the efficacy of PJCA for the treatment of large OLTs. In light of the available evidence, PJCA for the treatment of large OLTs cannot be currently recommended. LEVEL OF EVIDENCE: Level IV.

Osteochondral Lesions of the Subtalar Joint: Clinical Outcomes in 11 Patients.

OBJECTIVE: The purpose of this retrospective case series was to evaluate clinical outcomes following both conservative treatment and arthroscopic bone marrow stimulation (BMS) for the management of symptomatic subtalar osteochondral lesions (OCLs). DESIGN: All symptomatic subtalar OCLs with a minimum of 12 months follow-up having undergone either a conservative management or arthroscopic procedure were included. Patient-reported outcomes were collected via questionnaires consisting of the Foot and Ankle Outcome Score (FAOS), Numeric Rating Scale (NRS) of pain in rest, during walking, during stair climbing, and during running. In addition, return to sports data, return to work data, reoperations, and complications were collected and assessed. In total, 11 patients across 2 academic institutions were included (3 males, 8 females). The median age was 43 years (interquartile range [IQR]: 32-53). RESULTS: All patients underwent conservative treatment first; in addition, 9 patients underwent subtalar arthroscopic debridement with or without BMS. The median follow-up time was 15 months (IQR: 14-100). In the surgically treated group, the median NRS scores were 2 (IQR: 1-3) during rest, 3 (IQR: 2-4) during walking, 4 (IQR: 4-5) during stair climbing, 5 (IQR: 4-5) during running and the median FAOS score at final follow-up was 74 (IQR: 65-83). In the conservatively treated patients, the median NRS scores were all 0 (IQR: 0-0) and the median FAOS scores were 90 (IQR: 85-94). In the group of surgical treated patients, 4 were able to return to the same level of sports, 2 returned to a lower level of sports. Both conservatively treated patients returned to the sport and the same level of prior participation. All patients except one in the surgical group returned to work. CONCLUSIONS: This retrospective case series demonstrated that a high number of patients converted to surgery after initial conservative treatment. In addition, debridement and BMS show good clinical outcomes for the management of symptomatic subtalar OCLs at short-term follow-up. No complications nor secondary surgical procedures were noted in the surgically treated group. The high rate of failure of conservative treatment suggests that surgical intervention for symptomatic subtalar OCLs can be the primary treatment strategy; however, further research is warranted in light of the small number of patients.

Cartilage Biopsy for Autologous Cell-Based Repair of the Knee in the Wide-Awake Setting Using Needle Arthroscopy.

Chondral and osteochondral lesions of the knee are a commonly occurring pathology that can pose challenges to the treating surgeon. For the appropriate cartilage injury, autologous cell-based articular cartilage repair techniques have shown promising results. However, these treatments traditionally require 2 separate surgical procedures. Recent advances in needle arthroscopy technology have made it possible to conduct the first stage of autologous chondrocyte implantation surgery in the wide-awake office setting, mitigating cost and resource utilization. The purpose of this technical note is to serve as a proof of concept and describe the process of obtaining a cartilage sample in the wide-awake patient using a needle arthroscope.

In-Office Needle Arthroscopy of the Knee With Lateral Parapatellar Retinacular Release.

The lateral patellofemoral joint, composed of multiple soft-tissue structures, balances the knee by aiding patella tracking, stability, and force distribution. Arthroscopic lateral release is a well-described procedure that addresses patellofemoral knee pain and, in cases with patellar instability, may be combined with medial stabilization. In-office needle arthroscopy is an up-trending technique that simultaneously diagnoses and treats patellofemoral pathology in the office, leading to a quicker patient recovery, reduced cost, and improved patient satisfaction. The purpose of this Technical Note is to describe in-office needle arthroscopy technique to address patellofemoral pain and lateral patellar mal-tracking, with special consideration for achieving adequate local anesthesia, proper indications, adequate visualization, and the advantages of performing these procedures in the office rather than the operating room.

In-Office Needle Arthroscopy with Meniscal Repair for Meniscal Lesions of the Knee.

Meniscal injuries are a common cause of knee pain and are often an indication for knee arthroscopy, the most common orthopedic surgical procedure in the United States. In-office needle arthroscopy (IONA) is a described technique with the ability to diagnose and treat meniscal injuries in the office. IONA allows for diagnosis and treatment at a significantly deceased cost, with both quicker patient recovery, and improved patient satisfaction. The purpose of this technical report is to describe the technique for performing in-office needle arthroscopy for meniscal injuries of the knee, including the technique for obtaining adequate local anesthesia, proper indications, adequate visualization, and the advantages of performing these procedures in the office rather than the operating room.

Reproducible and Effective Biceps Tenodesis Method Utilizing In-Office Nano-Arthroscopy.

Biceps tendinopathy is a common cause of chronic anterior shoulder pain characterized by altered joint mechanics with considerable deficits in range of motion secondary to pain. The benefits of in-office nano-arthroscopy (IONA) include the ability to diagnosis and treat biceps tendinopathy, quicker patient recovery, reduced cost, and improved patient satisfaction. The purpose of this technical report is to describe the technique for performing IONA for biceps tendinopathy (biceps tenotomy/biceps tenodesis), with special consideration for obtaining adequate local anesthesia, proper indications, adequate visualization, and the advantages of performing these procedures in the office rather than the operating room.

In-Office Needle Arthroscopy With Cartilage Allograft Extracellular Matrix Application for Cartilage Lesions of the Knee.

Chondral and osteochondral lesions of the knee are a common cause of pain, mechanical symptoms, and swelling for patients. The benefits of in-office needle arthroscopy (IONA) include the ability to diagnose and treat chondral or osteochondral lesions in the office, quicker patient recovery, reduced cost, and improved patient satisfaction. The purpose of this technical note is to describe the technique for performing in-office needle arthroscopy for chondral or osteochondral contained lesions of the knee, with special consideration of the technique for obtaining adequate local anesthesia, proper indications, adequate visualization, and the advantages of performing these procedures in the office rather than the operating room.

Surgical Management of Chronic Achilles Tendon Ruptures: A Systematic Review and Proposed Treatment Algorithm.

Background: As no evidence-based treatment guidelines exist for chronic Achilles tendon rupture (CATR), a systematic review of the literature was performed to compare the different treatment options and recommend a literature-based algorithm. Methods: In June 2022, MEDLINE, Embase, and Cochrane Library databases were systematically reviewed based on the PRISMA guidelines. The level of evidence (LOE) and quality of evidence were evaluated, and statistics on clinical outcomes and complications were calculated. Results: Twenty-seven studies with 614 patients were included. Three studies were LOE III and 25 studies were LOE IV. The mean Achilles tendon rupture score improved from a preoperative weighted mean of 38.8 ± 12.4 to a postoperative score 90.6 ± 4.7. The overall complication rate was 11.4%. Single techniques were used in 23 studies and dual techniques were used in 5 studies. The FHL tendon transfer was the most frequently used technique. We devised an algorithmic approach based on time from injury to surgical intervention and the length of the gap between the tendon stumps: >3 months: FHL transfer; <3 months (a) gap <2 cm, end-to-end repair; (b) gap 2 to 5 cm, gastrocnemius transfer, (c) gap >5 cm, semitendinosus autograft. Conclusion: Surgical management of CATR produced improvements in patient-reported outcome scores at midterm follow up, but a high complication rate (11.4%) was noted. Our proposed treatment algorithm may assist in shared decision making for this complex problem.

In-Office Nano-Arthroscopy of the Shoulder with Acromioplasty.

Subacromial decompression with acromioplasty is among the most commonly performed shoulder procedures. The advantages of in-office nano-arthroscopy include the capability of diagnosing and treating subacromial impingement, swifter patient recovery, improved cost-effectiveness, and superior patient satisfaction. The purpose of this technical report is to describe our technique for performing in-office nano-arthroscopy for subacromial decompression (subacromial bursectomy and acromioplasty), with a particular focus on appropriate indications, providing sufficient local anesthesia, optimizing visualization, and discussing the advantages of the in-office setting compared to the operating room.

Validation of the Foot and Ankle Outcome Score (FAOS) for Osteochondral Lesions of the Ankle.

BACKGROUND: The purpose of this study was to validate the Foot and Ankle Outcome Score (FAOS) for osteochondral lesions of the talus (OLTs). We hypothesize that the FAOS will meet all 4 psychometric criteria for validity in this patient population. METHODS: From 2008 to 2014, a total of 208 patients with OLTs were included in the construct validity portion of the study. All patients completed FAOS and 12-Item Short-Form Health Survey (SF-12) scores. Twenty additional patients were prospectively recruited and were asked to complete questionnaires to determine the relevance of each of the FAOS questions as it related to their OLT. Forty-four patients completed the FAOS 1 month after the first FAOS to assess reliability via Spearman correlation coefficient. Responsiveness of the FAOS was assessed with 54 patients who had both preoperative and postoperative FAOS scores via Student paired t test with significance determined as P < .05. In total, 229 unique patients were included in this study. RESULTS: Statistically significant associations were found between all FAOS and SF-12 subscales (P < .01). The FAOS symptoms subscale demonstrated the lowest correlation with the SF-12 physical health domains. No floor or ceiling effects were identified. Weak correlations were calculated between the 5 FAOS subscales and the SF-12 mental component summary score. All FAOS domains met the threshold for acceptable content validity (score > 2.0). All FAOS subscales demonstrated acceptable test-retest reliability, with ICC values ranging from 0.81 (ADL) to 0.92 (Pain). CONCLUSION: This study demonstrates the acceptable yet moderate construct and content validity, reliability, and responsiveness of the FAOS for patients with OLTs of the ankle joint. We endorse the use of the FAOS in evaluating ankle OLTs in both the research and clinical setting and consider it a useful patient-reported, self-administered instrument following surgical intervention. LEVEL OF EVIDENCE: Level IV, retrospective case study.

Implications of obesity in patients with foot and ankle pathology.

Obesity is a growing problem defined as a body mass index of greater than 30 kg/m2. It is predicted that by 2030, 48.9% of adults will be classified as obese which expands surgical risk factors to a broad population while increasing healthcare costs at the same time in different socioeconomic groups. This specific population has been widely studied in multiple surgical fields and published studies have shown the implications in each of these fields. The impact of obesity on orthopedic surgical outcomes has been previously reported in several total hip and knee arthroscopy studies, with evidence indicating that obesity is strongly associated with an increased risk of post operative complications together with higher revision rates. In line with increasing interest on the impact of obesity in orthopedics, there has been a similar output of publications in the foot and ankle literature. This review article evaluates several foot and ankle pathologies, their risk factors associated with obesity and subsequent management. It provides an updated, comprehensive analysis of the effects of obesity on foot and ankle surgical outcomes, with the ultimate aim of educating both surgeons and allied health professionals about the risks, benefits, and modifiable factors of operating on obese patients.

The Role of Needle Arthroscopy in the Assessment and Treatment of Ankle Sprains.

Lateral ankle ligament complex injuries are most commonly managed nonoperatively. If no improvements have been made following conservative management, surgical intervention is warranted. Concerns have been raised regarding complication rates following open and traditional arthroscopic anatomical repair. In-office needle arthroscopic anterior talo-fibular ligament repair provides a minimally invasive arthroscopic approach to the diagnosis and treatment of chronic lateral ankle instability. The limited soft tissue trauma facilitates rapid return to daily and sporting activities making this an attractive alternative approach to lateral ankle ligament complex injuries.

In-Office Needle Arthroscopy for the Foot and Ankle.

In-office needle arthroscopy (IONA) has been a readily available tool dating back to the 1990s, primarily for diagnostic purposes. This technique was not fully accepted and implemented because of significant limitations with the image quality and lack of instrumentation available to simultaneously treat the identified pathologies. However, recent advancements in IONA technology have made it possible to perform arthroscopic procedures under local anesthesia in the office setting, which once required a full operating suite. IONA has revolutionized how we treat foot and ankle pathologies in our practice. IONA allows the patient to be an active participant in the procedure and provides an interactive experience. IONA can be used to treat a range of foot and ankle pathologies, including anterior ankle impingement, posterior ankle impingement, osteochondral lesions of the ankle joint, hallux rigidus, lateral ankle ligament repair, and tendoscopic treatment of Achilles, peroneal, and posterior tibial tendon disorders. Excellent outcomes with regard to subjective clinical outcomes, return to play times, and complications have been reported following IONA for these pathologies.

Lower re-rupture rates but higher complication rates following surgical versus conservative treatment of acute achilles tendon ruptures: a systematic review of overlapping meta-analyses.

PURPOSE: To systematically review and evaluate the current meta-analyses for the treatment of acute Achilles tendon rupture (AATR). This study can provide clinicians with a clear overview of the current literature to aid clinical decision-making and the optimal formulation of treatment plans for AATR. METHODS: Two independent reviewers searched PubMed and Embase on June 2, 2022 based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Assessment of evidence was twofold: level of evidence (LoE) and quality of evidence (QoE). LoE was evaluated using published criteria by The Journal of Bone and Joint Surgery and the QoE by the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) scale. Pooled complication rates were highlighted for significance in favour of one treatment arm or no significance. RESULTS: There were 34 meta-analyses that met the eligibility criteria, with 28 studies of LoE 1, and the mean QoE was 9.8 ± 1.2. Significantly lower re-rupture rates were reported with surgical (2.3-5%) versus conservative treatment (3.9-13%), but conservative treatment was favoured in terms of lower complication rates. The re-rupture rates were not significantly different between percutaneous repair or minimally invasive surgery (MIS) compared to open repair, but MIS was favoured in terms of lower complication rates (7.5-10.4%). When comparing rehabilitation protocols following open repair (four studies), conservative treatment (nine studies), or combined (three studies), there was no significant difference in terms of re-rupture or obvious advantage in terms of lower complication rates between early versus later rehabilitation. CONCLUSION: This systematic review found that surgical treatment was significantly favoured over conservative treatment for re-rupture, but conservative treatment had lower complication rates other than re-rupture, notably for infections and sural nerve injury. Open repair had similar re-rupture rates to MIS, but lower complication rates; however, the rate of sural nerve injuries was lower in open repair. When comparing earlier versus later rehabilitation, there was no difference in re-rupture rates or obvious advantage in complications between open repair, conservative treatment, or when combined. The findings of this study will allow clinicians to effectively counsel their patients on the postoperative outcomes and complications associated with different treatment approaches for AATR. LEVEL OF EVIDENCE: IV.

Intra-Tendinous Ganglion Cyst of the Peroneus Tertius: A Case Report and Literature Review.

BACKGROUND This article presents a rare case of an intra-tendinous ganglion cyst of the peroneus tertius. Ganglion cysts are benign lesions frequently seen in hand pathologies, but they are rarely seen in the foot and ankle. This article discusses the present case and similar previously reported cases in the English literature. CASE REPORT We present a case of a 58-year-old man with a 3-year history of right foot pain caused by a mass located at the dorso-lateral aspect of the midfoot. Preoperative MRI demonstrated a ganglion cyst arising from the peroneus tertius tendon sheath. The lesion was successfully decompressed in the office; however, it recurred 7 months later. As it was symptomatic, we elected to proceed with surgical resection. During dissection, it became apparent that the cyst was arising from an intrasubstance tear of the peroneus tertius tendon, and a branch of the superficial peroneal nerve was noted to be adherent to the pseudo-capsule. Following excision of the lesion and its expansile pseudo-capsule, the tear was repaired with tubularization of the tendon and external neurolysis of the nerve was performed. At 6 months after surgery, there was no recurrence of the lesion, and the patient was pain free and had regained normal physical function. CONCLUSIONS Intra-tendinous ganglion cysts are rare, especially in the foot and ankle. This makes it challenging for an accurate preoperative diagnosis. When a tendon is arising from a tendon sheath, we recommend exploration of the underlying tendon for an associated tear.

Advances in Cartilage Repair.

Osteochondral lesions of the ankle joint are typically associated with a traumatic etiology and present with ankle pain and swelling. Conservative management yields unsatisfactory results because of the poor healing capacity of the articular cartilage. Smaller lesions (<100 mm2 or <10 mm) can be treated with less invasive procedures such as arthroscopic debridement, anterograde drilling, scaffold-based therapies, and augmentation with biological adjuvants. For patients with large lesions (>100 mm2 or >10 mm), cystic lesions, uncontained lesions, or patients who have failed prior bone marrow stimulation, management with autologous osteochondral transplantation is indicated.
