We aimed to investigate a faulty ligamentization process of a failed reconstructed anterior cruciate ligament. In other words, we want to study ultrastructural alterations a failed ACL graft undergoes. Methods: Two patients who underwent revision ACL reconstruction for nontraumatic failure without discontinuity of the graft were included in the study. The first patient was a 40-year-old male who had undergone ACL reconstruction of his right knee 21 years back using the bone-patellar tendon-bone autograft. The second patient was a 23-year-old male who had sustained an ACL tear with a medial collateral ligament injury treated by isolated ACL reconstruction 3 years back using hamstring tendon autograft. We collected punch biopsy specimens from the failed ligaments of both the patients during revision ACL reconstruction. These specimens were examined for the density of collagen fibrils within a fascicle (per 1.5 μm2), cellular metabolism, and fibril diameter (nm) by transmission electron microscopy. Results: Fibroblasts of both the ligaments showed features of increased metabolism, more so in the first patient. Compared to the second patient, the fascicles of the first specimen were more loosely arranged. Both ligaments had a unimodal distribution of collagen fibrils. The first patient had a mean fibril diameter of 45.2 (+/−8.5) nm and an average fibril density of 376.8 fibrils per 1.5 μm2. The second patient had an average fibril diameter of 64.1 nm (+/−7) and a mean fibril density of 152.9 fibrils/1.5 μm2. The difference in these parameters of the two patients was statistically significant (P < 0.001). Conclusion: Our study suggests that the absence of thicker collagen fibrils with unimodal distribution, the altered density of the collagen fibrils within a fascicle, and ovoid fibroblasts with increased metabolism may symbolize bad ligamentization changes.","PeriodicalId":38088,"journal":{"name":"Journal of Arthroscopy and Joint Surgery","volume":"9 1","pages":"17 - 21"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49534754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 3 main causes of disruption include quadriceps tendon rupture, patellar fracture, or patellar tendon rupture. Clinical presentation can vary from asymptomatic to the acutely painful and swollen knee, but for most patients, there will be evidence of extensor lag and/or difficulty performing straight leg raise. A variety of treatment options have been described in the literature to date including nonoperative management with immobilization, particularly for patients with an extensor lag of <20°. Direct repair may be useful in the management of acute tendon ruptures; however, augmentation is now also recommended in addition. Options for augmentation include tendon autografts or synthetic materials. The use of allografts such as Achilles tendon allografts or complete extensor mechanism allografts and rotational flaps has also been described. Treatment of patellar fractures varies depending on fracture pattern, degree of extensor lag, presence of patellar component loosening, and patellar bone stock. The potential options for treatment include nonoperative management with immobilization, open reduction and internal fixation, patellectomy (either partial or complete), or revision surgery, although this list is not exhaustive. Outcomes are poor with complications including rerupture, postoperative infection, nonunion, or residual extensor lag with associated poor functional outcomes and high reoperation rates. There is a distinct lack of high-quality evidence in the literature at present, and as such, further research is required to make any recommendations for treatment.","PeriodicalId":38088,"journal":{"name":"Journal of Arthroscopy and Joint Surgery","volume":"9 1","pages":"1 - 7"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48623221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assessed the efficacy of intra-articular hyaluronate injection in patients below the age of 55 years. Methods: We reviewed our patient database from August 2013 to December 2016 for patients who received a fluoroscopic-guided intra-articular injection of hyaluronate. Those who had received interventional procedures within the preceding 12 months were excluded. We evaluated the response to the injection using the Oxford Shoulder Score (OSS). These scores were recorded before injection and at 6 weeks, 12 weeks, and 26 weeks postinjection. Radiographs were reviewed independently by two evaluators, and the severity of GHJ OA was categorized (mild, moderate, or severe) using the Samilson–Prieto classification. Results: Fifty-five patients were identified, with a mean age of 43 years (18.6–54.6 years). These cases were classified as being mild in 11 (20%), moderate in 21 (38%), and severe in 23 (42%) using Samilson-Prieto classification. In the severe group, there was a statistically significant improvement in the OSS at all time points. In the moderate group, there were statistically significant improvements at 6 weeks and 12 weeks but not at 6 months. In the mild group, there were no statistically significant changes. Conclusion: In patients under the age of 55 years with moderate-to-severe GHJ OA, there is a significant improvement in the OSS up to 12 weeks after intra-articular injection of hyaluronate, with improvements lasting up to 26 weeks in more severe cases. Hyaluronate is, therefore, a useful treatment option in younger patients and may potentially delay the need for arthroplasty.","PeriodicalId":38088,"journal":{"name":"Journal of Arthroscopy and Joint Surgery","volume":"9 1","pages":"28 - 33"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43337352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
