Arthroscopic suture anchor repair and debridement for refractory lateral epicondylitis show significant clinical improvement

PurposeTo retrospectively compare the clinical outcomes of arthroscopic suture anchor repair of the common extensor tendon (CET) and arthroscopic debridement of CET for the treatment of refractory lateral epicondylitis. MethodsPatients with refractory lateral epicondylitis who underwent arthroscopic surgery between August 2018 and September 2022 with a minimum of 1-year follow-up were included. All patients were divided into two groups based on whether they underwent suture anchor repair. The modified Nirschl technique was used to debride the CET lesions in all patients, and modified anchor repair was used for CET insertion reconstruction in patients after January 2021. In short, suture anchor fixation (single-row) was used in patients with tear areas less than 50% of the CET insertion, and suture-bridge fixation (double-row) was used in patients with tear areas greater than 50%. The outcomes, including the visual analog scale (VAS) score for pain, the Mayo Elbow Performance Score (MEPS), the quick Disabilities of the Arm, Shoulder and Hand (DASH) score, and surgical satisfaction, were measured one day preoperatively and at the latest follow-up. The proportion of patients achieving the minimal clinically important difference (MCID) was compared between the groups. ResultsA total of 62 patients (60% female) were included in the final analysis (30 in the debridement group and 32 in the repair group). The mean age of the cohort was 47.6 ± 7.3 years, with 77% of patients affecting the dominant arm. The follow-up time was 29.3 ± 3.2 (range: 19 - 35) months for the debridement group and 27.2 ± 5.4 (range: 20 - 37) months for the repair group (P = 0.073). Preoperative patient-reported outcomes were comparable between the groups and were significantly improved after surgery. Postoperatively, patients in the repair group had better MEPS score (95.8 ± 6.9 vs 91.2 ± 8.0; P = 0.017) and quick DASH scores (2.2 ± 3.9 vs 4.2 ± 3.9; P = 0.043), while there were no differences between the two groups in terms of VAS scores for pain during rest (0.1 ± 0.4 vs 0.1 ± 0.3; P = 0.933) or during activity (0.3 ± 0.8 vs 0.4 ± 0.6; P = 0.639). MCID achievement of VAS score during rest was similar between the repair group (97%) and the debridement group (93%, P = 0.607), while MCID achievement in the VAS score during activity, MEPS score, and quick-DASH score was 100% in both groups. ( All patients resumed their daily life and work after surgery, for a surgical satisfaction rate of 98.4%. ConclusionArthroscopic suture anchor repair and debridement of the CET insertion resulted in significant clinical improvement in patients with refractory lateral epicondylitis.

A Retrospective Study on Endoscopic Surgery for the Treatment of Paravertebral Abscess in Spinal Tuberculosis Patients.

Spinal tuberculosis (TB) remains a significant global health concern, necessitating the development of innovative treatment strategies. This clinical study aimed to evaluate the efficacy and safety of endoscopic debridement as a minimally invasive approach for treating paravertebral abscesses in patients with spinal tuberculosis. A total of 52 patients diagnosed with paravertebral tuberculosis abscesses were enrolled in this retrospective study. Patients were assigned to two groups: the endoscopic debridement group (n = 30) and the conventional open surgery group (n = 22), based on the type of surgery they received. Clinical outcomes were assessed at baseline, post-treatment, and follow-up visits at regular intervals, including surgery time, intraoperative blood loss, total hospital stay duration, pain relief, and neurological improvement. The results of this study demonstrate that endoscopic debridement is a highly effective treatment for paravertebral abscesses in patients with spinal TB. Patients in the endoscopic debridement group experienced significant improvements in surgery time, intraoperative blood loss, total hospital stay duration, pain relief, and neurological improvement compared to those in the conventional open surgery group. Additionally, the endoscopic approach resulted in fewer complications, such as wound infections and postoperative instability, with no cases of recurrence observed during the follow-up period. Therefore, this clinical study highlights the potential of endoscopic debridement as a safe and effective treatment modality for spinal tuberculosis. The technique not only effectively eliminates infected tissue but also ensures faster patient recovery and reduces postoperative complications. Additional research and long-term follow-up studies are necessary to confirm the long-term effectiveness and safety of endoscopic debridement as the standard treatment for spinal tuberculosis.

Assessing the role of wound debridement in pyoderma gangrenosum-A retrospective cohort study.

The role of wound debridement in pyoderma gangrenosum (PG) is controversial, largely due to concerns regarding pathergy. This study sought to evaluate the clinical outcomes and utility of wound debridement in PG management. We conducted a retrospective cohort study of 104 patients diagnosed with PG at a single tertiary referral centre, stratified into two treatment groups: those receiving debridement in conjunction with immunosuppressive therapy (n = 38) and those treated with immunosuppression alone (control group, n = 66). The primary outcomes measured were remission (absence of active PG lesions without necessitating additional treatment), time to remission and disease progression (new lesions or expansion of existing ones). Remission was achieved by 60.53% (n = 23) in the debridement group versus 87.88% (n = 58) in the control group (p = 0.003). The mean time to remission was 12.3 months for the debridement group versus 8.67 months for the control group (p = 0.2). Multivariate Cox regression analysis indicated that debridement significantly decreased the likelihood of disease remission (adjusted hazards ratio [HR]: 0.45, 95% confidence interval [CI]: 0.26-0.78, p = 0.005). Disease progression was significantly higher in the debridement group (68.42%, n = 26) compared to the control group (15.15%, n = 10) (p < 0.001). Additionally, 28.95% (n = 11) of patients in the debridement group required repeated procedures, and 10.53% (n = 4) underwent amputations due to deteriorating conditions. The timing and duration of immunosuppressive therapy relative to the procedure did not mitigate the risk of post-surgical exacerbations. These findings suggest that debridement is associated with poorer healing outcomes in PG, advocating for its contraindication in the management of this condition.

Save the subchondral bone plate: Debridement versus bone marrow stimulation in acetabular cartilage defects over 60 months of follow-up.

Bone marrow stimulation is a common treatment for full-thickness cartilage defects in the hip joint. However, common procedures may result in poor fibrous repair tissue and changes to the subchondral anatomy. This study investigated the clinical outcome of a cohort of International Cartilage Repair Society (ICRS) grades 3 and 4 cartilage defects treated with bone marrow stimulation compared to those who received simple debridement/chondroplasty. In this retrospective registry study, 236 patients with uni-focal acetabular chondral lesions of the hip up to 400 mm² (mean 177.4 ± 113.4 mm²) and of ICRS grade ≥3 with follow-up of at least 12 months (mean 33.2 ± 15.3 months) were included. Eighty-one patients underwent bone marrow stimulation (microfracture: n = 44, abrasion: n = 37) besides treatment of the underlying pathology, 155 patients underwent defect debridement/chondroplasty. The patient-reported outcome was measured using the International Hip Outcome Tool 33 (iHOT33) score and the Visual Analogue Scale (VAS) for pain. iHOT33 and VAS both improved highly statistically significantly (p < 0.001) in the debridement group after 6, 12, 24, 36 and 60 months compared to the preoperative scores, whereas iHOT33 and VAS after microfracture or abrasion did not show statistically significant changes over time. Twenty-four and sixty months postsurgery the debridement group revealed significant higher scores in the iHOT33 compared to the bone marrow stimulation groups. Patients with chondral lesions of the hip ≤400 mm2 sustainably benefit from arthroscopic debridement under preservation of the subchondral bone plate in terms of functional outcome and pain in contrast to patients treated with bone marrow stimulation. These findings discourage the currently recommended use of microfracture in the hip joint. Level III.

Improved Short-Term Prognosis of Pediatric Partial-Thickness Burns: Emergency Conservative Debridement Under Topical Anesthesia.

Early wound management for pediatric patients with partial-thickness burns in the emergency department remains debatable. This study aims to evaluate the value of emergency conservative debridement under topical anesthesia in improving short-term prognosis of pediatric partial-thickness burns. This retrospective cohort study enrolled children with partial-thickness thermal burns presenting to the emergency department within 6 hours postburn. All the enrolled patients were divided into 2 groups: the debridement group and the dressing group. The associations between emergency conservative debridement and time to reepithelialization was analyzed by using Kaplan-Meier curves with log rank test and multivariate Cox regression analysis. Moreover, the associations between emergency conservative debridement and in-hospital cost and length of stay were also evaluated. All baseline characteristics between groups were comparable (all P > 0.05). Emergency conservative debridement under topical anesthesia significantly decreased the median value of time to reepithelialization (13 vs 14 days, P = 0.02). Cox regression analysis showed that emergency conservative debridement significantly improved wound reepithelialization after adjusting for burn size (odds ratio, 4.07; 95% confidence interval, 1.64-10.11; P < 0.01). The mean length of stay of patients receiving conservative wound debridement was lower than that of patients in the wound dressing group (14.3 ± 7.3 vs 18.8 ± 10.4 days, P < 0.01), but not in terms of mean in-hospital cost per 1% total body surface area (2.8 ± 1.9 vs 3.0 ± 2.1 × 103 RMB per 1% total body surface area, P = 0.58). Emergency conservative debridement of pediatric partial-thickness burns under topical anesthesia significantly improves the wound healing outcomes without increasing health care burden.

Associations Between Systolic Pressure, Vascular Waveform, and Volume Flow with Debridement or Amputation Treatment Decisions in Diabetic Foot Ulcer Patients.

Diabetic foot ulcer disease, affecting 6.3% of the global population, necessitates crucial decisions regarding debridement and amputation, with substantial cost, morbidity, and mortality implications. This study's primary goal is to determine effective vascular examination modalities, including systolic blood pressure, vascular waveforms, and blood volume flow to guide optimal treatments for diabetic foot patients. This cross-sectional study at Cipto Mangunkusumo General Hospital aimed to identify effective vascular examination modalities, such as systolic blood pressure, vascular waveforms, and blood volume flow, to guide treatment choices for diabetic foot patients. The study included 38 subjects, equally split between debridement and amputation groups. Notably, the presence of a biphasic pattern in popliteal artery vascular examinations was associated with the decision for amputation in diabetic foot patients (p < 0.05). The Chi-square test revealed that a biphasic ultrasound pattern served as a predictive factor for amputation among diabetic foot patients, with three times more biphasic patients choosing amputation over debridement. Conversely, assessments of popliteal artery systolic pressure, common femoral artery waveform, popliteal artery volume flow, and common femoral artery volume flow showed no significant correlations with the choice of debridement or amputation treatment for diabetic foot patients. In summary, ultrasound assessment of vascular waveform in the popliteal artery emerges as a predictive factor for amputation or debridement in diabetic foot patients.

How Does Intentional Apical Foraminal Enlargement Affect the Foramen and Root Canal Morphology?

IntroductionThis study assessed the effect of intentional foraminal enlargement on the foramen and the apical root canal morphology. MethodSixty mesial roots of mandibular molars were scanned by micro-computed tomography. Their apical foramina were photographed with a stereomicroscope before and after preparation. Three groups were formed (n = 20) according to the working length (WL). G-1: foramen - 1 mm; G0: foramen; and G+1: foramen + 1 mm. Each group originated 2 subgroups (n = 10): G-1: Buchanan's patency (size 10 K-type file) and foraminal debridement (sizes 20, 25 and 30 K-type files); G0 and G+1: rotary foraminal enlargement (ProDesign S size 25/.08) or reciprocating foraminal enlargement (R25). The area, perimeter, transportation, and noninstrumented walls of the foramen were evaluated. The root canal transportation and the centering index of preparation at 1, 3 and 5 mm from the foramen were also assessed. Data were compared statistically (α = 5%). ResultsThe instruments used at the foramen and 1 mm beyond promoted foraminal enlargement and transportation. Regarding NIW, there was no difference between mechanized foraminal enlargements performed at the foramen or 1 mm beyond, similar to the manual foraminal debridement group (P > .05). There was no difference in transportation and centralization at 1-, 3-, and 5-mm apical levels, regardless of the instrumentation systems. ConclusionMechanical preparation at the foramen, or 1 mm beyond, resulted in foraminal enlargement, transportation and were not able to touch all root canal walls that delimit the foramen.

Appraising and comparing the role of autogenous periosteal graft as a barrier membrane in the treatment of intrabony defects in chronic periodontitis cases: A systematic review and meta-analysis.

Periodontal regeneration refers to procedures aimed at restitution of lost supporting tissue around the periodontally compromised tooth. Regenerative procedures very often include the use of barrier materials to encourage the growth of key surrounding tissues. The current study aimed to evaluate the effectiveness of autogenous periosteal graft as a barrier membrane for the treatment of intrabony defects in chronic periodontitis patients. A total of four data bases MEDLINE (by PubMed), Cochrane database, EBSCO, and Google Scholar were explored to identify the studies in English up to December 2022. An additional hand search of relevant journals was also done. A team of three independent reviewers screened the retrieved articles using the inclusion criteria. Randomized control trials (RCTs) evaluating the effectiveness of autogenous periosteal grafts in the treatment of intrabony defects in chronic periodontitis cases were included in the study. A total of six relevant articles were recognized for data procurement. A total of 117 patients with 68 sites with an age range between 18 years and 55 years were selected. Outcome variables examined were pocket depth (PD), clinical attachment level (CAL), radiographic bone defect fill (BDF), gingival recession (GR), plaque index (PI), gingival index (GI) and bleeding on probing (BOP). Data were analyzed using Revman 5.3 software. The mean differences and 95% confidence interval were used to illustrate the estimate of effect size. There is an equal effect in both groups for the PI, GI, and BOP reduction. For PD reduction, the result was in the favor of periosteal graft with open flap debridement (OFD) group. For CAL gain, radiographic BDF and GR, results also favored the periosteal graft, but no statistically significant difference was found amongst the groups. Within the limitation of the study, it seems that the autogenous periosteal graft can be used successfully along with OFD to treat intrabony defects in chronic periodontitis patients.

Assessing Second Debridement Timing and Mortality in Necrotizing Soft Tissue Infections.

Patients with necrotizing soft tissue infection undergo an average of 4-5 debridements per hospital admission. Optimal timing for initial debridement is emergent. Second debridement is universally recommended to occur within 24hours of the first, but no studies have successfully evaluated this time frame. Prior work has suggested that delays in second debridement are associated with increased mortality, and that few patients receive second debridement within 24hours. We performed a retrospective cohort study at a single center from 01/01/08 to 09/01/2021. The explanatory variable was whether the subject received second debridement within 24hours of initial debridement. The primary outcome was in-hospital mortality. Baseline characteristics were collected. Subjects were stratified into 2 groups by time between first and second debridement: <24 and ≥24hours. Variables were compared using Fisher's exact and Wilcoxon rank-sum tests. 77 patients met inclusion criteria. The median overall time to second debridement was 40 hours. 12 subjects received second debridement within 24hours (15.6%). There was no difference in in-hospital mortality between the <24 (n = 3, 25.0%) and ≥24-hour second debridement groups (n = 4, 6.2%; P = .07). The 2 groups did not differ by secondary outcomes, including total number of debridements, ICU LOS, or wound closure. No difference in mortality was observed between subjects undergoing second debridement within 24 vs after 24hours. Only 16% of subjects received second debridement within the recommended 24-hour time interval. Further study is required to identify the optimal timing of second debridement.

Comparison of the Functional Outcomes of Arthroscopic Debridement and Repair of Bursal-side Partial-thickness Rotator Cuff Tears

Background: To compare the clinical and functional scores of arthroscopic debridement and repair (conversion to full thickness) surgeries in patients with bursal-side partial-thickness rotator cuff tears (BPTRCT). Materials and Methods: A single-center retrospective study was conducted to compare the arthroscopic debride-ment and arthroscopic repair for BPTRCT performed between March 2017 and September 2021. Arthroscopic debridement patients were grouped as Group 1 and the repair group as Group 2. A total of 98 patients with an average age of 57.5 years (range 29-83 years), including 41 male and 57 female patients, met the inclusion criteria. VAS (Visual Analogue Scale) and UCLA (University of California Los Angeles) shoulder scores applied in the preopera-tive period and in the 12th month of the postoperative clinical follow-ups were evaluated. In addition to the pre-operative and postoperative comparison of both scores, their improvement of these scores was also compared. Results: The mean age of the repair group and the debridement group was 64.4 ±11.02 and 52.6 ±11.24, respective-ly. No significant difference between the two groups was observed in terms of demographic characteristics (p˃0.05). The mean operation time was 91.46 ±16.44 min in the repair group and 49.82 ±13.46 min in the debridement group. The VAS score dramatically improved, from preoperative 5.10±1.23 to postoperative 3.68±1.33 points in the deb-ridement group and from preoperative 5.17±1.35 to postoperative 3.58±1.16 points in the repair group. The two groups had no statistically significant difference in postoperative VAS scores (p=0.991). Preoperative and postopera-tive VAS score improvement was also compared between the groups, however, there was also no statistically signifi-cant difference in terms of VAS score changes (p=0.132). The UCLA scores also dramatically improved, from pre-operative 17.14±4.19 to postoperative 24.57±5.04 points in the debridement group and from preoperative 17.46±5.05 to postoperative 25.48±5.61 points in the repair group. No statistically significant difference was ob-served between the two groups in terms of postoperative UCLA scores (p=0.361). In the postoperative first-year follow-up, no re-tears were observed either in the debridement or in the repair group. Conclusions: Both arthroscopic debridement and arthroscopic repair surgeries provide clinically comparable suc-cessful results and high satisfaction for patients with bursal-side rotator cuff tears. No statistically significant differ-ence was observed between these two methods. Easier early postoperative rehabilitation seems to be the main advantage of the debridement method.

Longitudinal Analysis of the ASES and Constant-Murley Scores, and the Internal Rotation/Shift and Jobe Tests Following Arthroscopic Repair of Supraspinatus Lesions.

It is essential to investigate patients post-surgery using functional surveys like the American Shoulder and Elbow Surgeons Shoulder (ASES) and the Constant-Murley shoulder (CMS) scores, as well as clinical tests, such as the Internal Rotation and Shift (IRO/Shift) and Jobe tests. In this study, 51 out of an initial 87 patients underwent an arthroscopic supraspinatus repair (22 single-row, 16 double-row, 13 debridement). Testing occurred pre-surgery, and 3 and 6 months post-surgery. Both surveys showed significant improvements over time among all 87 patients, but there were no differences between groups (lesion/no lesion) (p > 0.815) or time × group (p > 0.895). The IRO/Shift test showed a stronger ability to distinguish between both groups (positive vs. negative) with respect to the ASES and CMS scores over time, but the Jobe test did not (p > 0.100). Improvements in the CMS scores and the Jobe test were lower following repair compared to the ASES and IRO/Shift test. Most patients returned to adequate levels of functional abilities at 6 months post-surgery. The time required to return to activities of daily living and negative clinical tests was longer for the double-row repair patients compared to the single-row and debridement groups. In conclusion, both the functional surveys and the clinical tests demonstrated improvements following surgery.

Prospective Randomized Clinical Trial of Arthroscopic Repair Versus Debridement for Partial Subscapularis Tendon Tears More Than Half of the Entire First Facet.

Most outcome studies on subscapularis (SSC) tendon tears have focused on large SSC tears rather than partial SSC tendon tears. Therefore, the optimal treatment for partial SSC tendon tears more than half of the first facet of the entire SSC footprint has not yet been clearly defined. To prospectively investigate the clinical and radiological results between the arthroscopic repair group and the debridement group in SSC partial tear (Yoo and Rhee classification, type 2B: SSC tendon tears of more than half of the entire first facet). Randomized controlled trial; Level of evidence, 1. A total of 65 patients with SSC tendon type 2B tears were randomized to arthroscopic debridement (n = 33) or arthroscopic repair (n = 32). Clinical evaluation of the patients was performed on the day before surgery and 6 months, 1 year, 2 years, and 5 years postoperatively using active range of motion measurements and other validated scores (pain visual analog scale scores, function visual analog scale scores, Constant score, American Shoulder and Elbow Surgeons score). In addition, SSC muscle strength was measured using instruments in the belly-press position. Magnetic resonance imaging (upper and lower SSC muscle diameters, Goutallier grades) was performed on the day before operation as well as 6 months and 2 years postoperatively. There were no clinically or statistically significant differences between the arthroscopic debridement and arthroscopic repair groups with respect to active range of motion, pain visual analog scale scores, function visual analog scale scores, Constant scores, or American Shoulder and Elbow Surgeons scores. There was a statistically significant increase in SSC muscle strength in the repair group compared with the debridement group at 5 years postoperatively (P = .013). Magnetic resonance imaging assessment was also not significantly different between the 2 groups. There were no differences in the patient-reported outcomes of patients with partial SSC tears treated with either arthroscopic debridement or repair, although there was an increase in SSC muscle strength associated with repair, the clinical importance of which may warrant further research.

Arthroscopic Biological Augmentation With Subacromial Bursa for Bursal-Sided Partial-Thickness Rotator Cuff Tears.

Augmentation with subacromial bursa has not been fully established in bursal-sided partial-thickness rotator cuff tears (PT-RCTs). To compare the results of acromioplasty + arthroscopic debridement versus acromioplasty + augmentation with subacromial bursa for Ellman type 2 PT-RCTs involving 25% to 50% of the tendon surface area. Cohort study; Level of evidence, 3. Included were 40 patients (mean age, 47.8 years) with Ellman type 2 PT-RCTs whose symptoms did not regress despite 3 months of nonoperative treatment. The patients underwent either acromioplasty + debridement (group A; n = 18) or acromioplasty + augmentation (group B; n = 22). Outcome scores (visual analog scale [VAS] pain score, Constant-Murley score [CMS], and American Shoulder and Elbow Surgeons [ASES] score) were obtained preoperatively and at 6, 12, and 18 months postoperatively. Magnetic resonance imaging (MRI) scans performed at 6 months postoperatively were used to determine the integrity and state of healing. There were no significant differences between groups A and B in preoperative VAS, CMS, or ASES scores, and patients in both groups saw significant improvement at each follow-up time point on all 3 outcome scores (P = .001 for all). Scores on all 3 outcome measures were significantly better in group B than group A at each postoperative time point (P < .05 for all). Postoperative MRI scans revealed persistent partial tears in 5 of 18 patients in group A compared with 2 of 22 patients in group B (P < .05). Conversion to full-thickness tear (3/18 patients) was seen only in group A. Patients who underwent biological augmentation of their PT-RCTs had improved outcome scores compared with those treated with acromioplasty and debridement alone.

A Comparison between the Use of Patient-worn Virtual Reality in Wound Care and Hand Surgery: How Does Virtual Reality Work?

Twenty-five wound care patients were randomly assigned to either a VR group or non-virtual reality (NVR) group, singly blinded. Pre-debridement, peri-debridement, and immediately postdebridement anxiety, fun, and pain scores were collected using a Likert scale (0 = least; 10 = most) from each group of patients. These measurements were compared among the VR versus NVR group in the setting of routine wound debridement procedures. The results are compared with our previously published data on patients who underwent wide awake local anesthesia no tourniquet (WALANT) hand surgery. The WALANT surgery patients using VR experienced significant reduction in anxiety and increase in fun compared with the NVR group. In the wound debridement group with VR, there was improved fun, but no statistically significant reduction in pain or anxiety when compared with the NVR group. The mean score for anxiety was higher for awake hand surgery than for wound debridement cases (3.3 versus 1.7, P = 0.004). VR seems to be more effective in higher anxiety settings, could VR work via a neurological mechanism akin to the Melzack and Wall gate control theory of pain? VR may act primarily on the anxiety axis, providing negative feedback via cortical pathways to the amygdala.

Modified ulcer debridement versus argon laser photocoagulation as an adjunctive therapy for treatment of fungal keratitis

Abstract Background Mycotic keratitis is a disorder due to fungal invasion into the corneal stroma. Early diagnosis and immediate management are critical to avoiding long-term consequences with fungal keratitis as it grows quickly and can cause corneal ulcers and vision loss. Aim To compare the effect of argon laser photocoagulation with tissue debridement as a supportive therapy for treatment of fungal keratitis. Patients and methods In this prospective study, 40 patients with resistant fungal keratitis were evaluated and treated with argon laser and debridement as a supportive therapy in resistant cases.The duration of the study was 12 months with follow-up period of 3 months. Results Of 20 eyes, 18 responded to argon laser with complete epithelial healing occurring in the range of 2–4 weeks, with mean of 47.50 ± 7.96 weeks. On the contrary, 16 of 20 eyes responded to debridement, with complete healing occurring in the range of 3–7 weeks, with a mean of 46.15 ± 7.57 weeks. Two cases needed amniotic membrane graft in the laser group, whereas four cases in the debridement group. Conclusion Argon laser therapy is the most effective supplementary step in the treatment of resistant fungal keratitis. Argon laser therapy is preferred to debridement in the management of resistant fungal corneal ulcer and has a significant effect on reducing corneal scarring and improvement of visual acuity.

Ten-Year Survivorship, Outcomes, and Sports Participation in Athletes After Primary Hip Arthroscopy for Femoroacetabular Impingement Syndrome

Background: Hip arthroscopy is an effective treatment tool for athletes with femoroacetabular impingement (FAI) syndrome. However, long-term data are scarce. Purpose: To assess survivorship, minimum 10-year patient-reported outcome measures (PROMs), and sports participation after primary hip arthroscopy for FAI syndrome in athletes and to perform a propensity-matched comparison between patients undergoing labral debridement and labral repair. Study Design: Cohort study; Level of evidence, 3. Methods: Athletes who underwent hip arthroscopy for FAI syndrome between February 2008 and December 2010 were eligible. Exclusion criteria were other ipsilateral hip condition, Tönnis grade ≥2, or no baseline PROMs. Survivorship was defined as no conversion to total hip arthroplasty. The Patient Acceptable Symptom State (PASS), minimal clinically important difference (MCID), maximum outcome improvement (MOI) satisfaction threshold, and sports participation were reported. A propensity-matched comparison between labral debridement and labral repair was performed. Two additional propensity-matched subanalyses were performed for capsular management and cartilage damage. Results: In total, 189 hips (177 patients) were included. The mean ± SD follow-up was 127.2 ± 6.0 months. Survivorship was 85.7%. Significant improvement in all PROMs was reported (P < .001). A total of 46 athletes with labral repair were propensity matched to 46 athletes with labral debridement. This subanalysis demonstrated significant and comparable improvement in all PROMs at minimum 10-year follow-up (P < .001). For the labral repair group, the PASS achievement rates were 88.9% for the modified Harris Hip Score (mHHS) and 80% for the Hip Outcome Score–Sport Specific Subscale (HOS-SSS); the MCID achievement rates were 80.6% for the mHHS and 84% for HOS-SSS; and for the MOI satisfaction threshold, rates were 77.8%, 80.6%, and 55.6% for the mHHS, Nonarthritic Hip Score, and visual analog scale, respectively. For the labral debridement group, the PASS achievement rates were 85.3% for the mHHS and 70.4% for the HOS-SSS; the MCID achievement rates were 81.8% for the mHHS and 74.1% for HOS-SSS; and for the MOI satisfaction threshold, rates were 72.7%, 81.8%, and 66.7% for the mHHS, Nonarthritic Hip Score, and visual analog scale. Total hip arthroplasty conversions occurred significantly sooner with labral debridement than labral repair (P = .048). Age was identified as a significant predictor of achieving the PASS. Conclusion: Primary hip arthroscopy for FAI syndrome in athletes results in 85.7% survivorship and sustained PROM improvement at a minimum 10-year follow-up. A significant time delay to total hip arthroplasty conversion at 10-year follow-up was reported with labral repair over debridement, although this should be interpreted with caution, as the total number of conversions was small.

Acetabular Labral Repair and Selective Labral Debridement Show No Significant Difference in Clinical Outcomes at a Minimum 2-Year Follow-Up

To compare the outcomes of arthroscopic labral repair using looped type suture with a matched-pair selective labral debridement with a minimum 2-years follow-up. We identified 378 patients undergoing primary arthroscopic labral repair using loop-suture and selective labral debridement from January 2, 2018, to December 28, 2020. The labral repair group was matched 1:1 to a selective labral debridement control group by age, sex, body mass index, follow-up period, lateral center-edge angle, Tönnis grade, and preoperative joint space. Before surgery, 3-Tesla radial magnetic resonance imaging with a 3-dimensional double-echo steady-state sequence was obtained following failed nonoperative treatment lasting more than 3 months. Follow-up imaging was conducted at a minimum of 2 years. In both groups, the ratio of positive slices in which a disrupted chondrolabral junction was observed between the 2 o'clock and 11 o'clock positions was measured. Patient-reported outcome scores included the Harris Hip Score, visual analog score, Hip Outcome Score Activities of Daily Living Subscale, and Hip Outcome Score of Sport-Specific Subscale. In total, 76 patients of the repair group were matched to 76 controls with a minimum 2-years follow-up (repair vs control: 2.6 ± 0.4 vs 2.6 ± 0.4 years, P= .775). The repair group experienced a 2-fold improvement (0.6 ± 0.1 to 0.3 ± 0.1, P＜.001). Although the selective debridement group experienced a 3-fold improvement (0.3 ± 0.1 to 0.1 ± 0.1, P＜.001). Significant improvement of the patient-reported outcome was shown in both groups at final follow-up without significant difference between the 2 groups. The mid-term clinical outcomes are comparable between the labral repair using looped type suture and selective labral debridement group. Although a gap between the labrum and articular cartilage may appear in 3-dimensional double-echo steady-state magnetic resonance imaging results after labral repair, it does not correspond with clinical outcomes.

29-LB: Multicenter, Randomized Controlled Clinical Investigation Evaluating a Unique Micro Water Jet Technology Device vs. Standard Debridement in the Treatment of Diabetic Foot Wounds

Background: Proper debridement of the wound base is critical to facilitate wound granulation and closure in non-healing diabetic foot ulcers(DFUs). A unique micro water jet device has been developed and recently granted breakthrough designation for treatment of DFUs by the Foot and Drug Administration(FDA) that precisely cleans acute and chronic wounds in a tissue-preserving manner while performing a precise mechanical cleaning and stimulation of the wound base to enhance granulation and healing. Methods: 170 patients were screened, and 96 patients were enrolled for the analysis, in a two arm randomized controlled trial. DFUs that were non-healing for at least 4 weeks, with adequate blood flow and were void of clinical infection or osteomyelitis were entered into 2 weeks of screening. Those that met all the qualifications were randomized to receive either weekly micro jet wound debridement or standard sharp debridement along with SOC wound dressing and offloading. Both groups were followed for 16 weeks. The primary study endpoint was healing at 16 weeks and the secondary endpoints included a safety analysis. Results: At 16 weeks 65%(28/43) of the Micro Water jet treated DFUs healed compared with 42%(22/53) treated with standard sharp debridement p=0.021 (unadjusted). Further, at 16 weeks, the safety analysis showed with regard to wound related adverse events (AE) and serious adverse events (SAE); 4 AEs and 1 SAE occurring in the Micro Water jet group versus 12 AEs and 4 SAEs in the standard sharp debridement group. Conclusion: The micro water jet device was able to statistically significantly close more refractory DFUs over 16 weeks, without the need for any advanced biologic or graft. Further, the number of wound related infections and hospitalizations were 75% less in those patients treated in the Micro Water jet group. Further evaluation is warranted to validate these initial promising findings. Disclosure D. G. Armstrong: Research Support; Medaxis LLC. R.

Safety and efficacy of waterjet debridement vs. conventional debridement in the treatment of extremely severe burns: A retrospective analysis

IntroductionPatients with extremely severe burns often require rapid wound closure with a tangential excision or escharectomy combined with a skin graft to reduce life-threatening complications such as infection. Traditional tangential excision surgery using the Watson or Humby knife does not allow accurate excision of necrotic tissue and often removes too much active tissue, which is detrimental to the rapid healing of the wound. Importantly, the Versajet hydrosurgical system, with its smaller handle, allows for more precise excision of necrotic burn tissue and preserves more active dermal tissue, positively affecting wound healing and scarring. This study compared the safety and efficacy of hydrosurgical combined with autologous skin grafting to conventional excision combined with autologous skin grafting in patients with extremely severe burn. MethodsInformation of sixty burn patients with total body surface area (TBSA) > 50 % treated at the first affiliated hospital of Anhui Medical University from January 2019 to August 2022 were analyzed. The patients were divided into a conventional debridement group (n = 37) and a hydrosurgical debridement group (n = 23) according to the approach used. The hydrosurgical debridement group and the conventional debridement group were compared from the difference between the duration of the first debridement surgery, wound healing time, the changes of red blood cells and hemoglobin concentration postoperative, total blood transfusion, hospitalization cost, skin grafting frequency, procalcitonin, wound bacterial culture, albumin and prealbumin. ResultsInformation on age, gender, weight, inhalation injury, hypovolemic shock, preoperative procalcitonin, preoperative albumin, preoperative prealbumin, the operation frequency (n ≥ 3), preoperative trauma culture and postoperative trauma culture were compared between both groups (P > 0.05). Operative time and wound healing time were significantly shorter in patients with hydrosurgical debridement combined with autologous skin grafting than those in the control group (P < 0.05), while hospitalization costs were not significantly different between the two groups (P > 0.05). The changes of red blood cells and hemoglobin concentration during the postoperative period in the hydrosurgical debridement group were less significantly than those in the conventional debridement group (P < 0.05). The total amount of red blood cells transfused during hospitalization was significantly lower in the hydrosurgical debridement group than that in the conventional debridement group (P < 0.05), but the total amount of fresh frozen plasma transfused during hospitalization was not statistically significant between the two groups (P > 0.05). Albumin on the third day after surgery and prealbumin on the first, third and fifth day after surgery improved more significantly than those in the control group(P < 0.05), however, there were no significant differences between the two groups in albumin on the first and fifth postoperative days (P > 0.05). The PCT level in the conventional debridement group was significantly higher than that in the hydrosurgical debridement group on the first, third and fifth days after surgery(P < 0.05). ConclusionThe hydrosurgical debridement group presented with shorter operative time, less blood loss during surgery, faster postoperative nutritional recovery, less postoperative inflammatory response and faster wounds healing, and did not increase the hospitalization cost, postoperative bacterial culture of the wounds and the number of skin grafting surgeries. In patients with extremely severe burn, hydrosurgical debridement combined with autologous skin grafting group is safer and more effective than those in the conventional debridement combined with autologous skin grafting group.

Both Labral Debridement and Labral Repair Result in >90% Total Hip Arthroplasty-free Survival at 5-Year Follow-Up: An Analysis of the German Cartilage Registry (KnorpelRegister DGOU)

To compare clinical outcome parameters between labral debridement and repair by analyzing the dataset of a multinational registry. The data are based on the hip module of the German Cartilage Registry (KnorpelRegister DGOU). The register included patients designated for cartilage or femoroacetabular impingement surgery (up to July 1, 2021; n= 2725). The assessment consisted of the patient's characteristics, the type of labral treatment, the length of labral therapy, the pathology, the grade of cartilage damage, and the type of performed approach. The clinical outcomes were documented by the international hip outcome tool via an online platform. Separated Kaplan-Meier analyses were used for total hip arthroplasty (THA)-free survival rates. The debridement group (n= 673) showed a mean score increase of 21.9 ± 25.3 points. The repair group (n= 963) had a mean improvement of 21.3 ± 24.6 (P > .05). The 60-month THA-free survival rate was 90% to 93% for both groups (P > .05). A multivariance analysis showed that the grade of cartilage damage was the only independent statistically significant factor (P= .002-.001) influencing patients' outcomes and THA-free survival. Labral debridement and repair led to good and reliable results. However, these results should not be interpreted with the conclusion that the cheaper and technically easier labral debridement is the recommended treatment due to comparable results in the present study. The clinical outcome and the THA-free survival seemed to be more influenced by the grade of cartilage damage. Level III, retrospective comparative therapeutic trial.
