An 87-year-old female underwent right TKA followed by left TKA 5 months later. Six weeks after left TKA, a painful subcutaneous induration appeared in the left medial thigh. Magnetic resonance imaging revealed a 30∗50-mm multifocal mass. The cystic fluid was brown and cloudy, indicating an infected cyst. Oral antimicrobial therapy was initiated for 7 days. Nine weeks after the left TKA, a left calcaneal fracture occurred. Subsequently, edema of the lower extremities and pain in the left knee gradually developed. Arthrocentesis was performed twice: joint fluid Gram staining and culture examination were negative. However, at 12.5 weeks, an alpha-defensin test of the synovial fluid was positive. Therefore, PJI was diagnosed. DAIR was performed, followed by multiantibiotic therapy. The infection subsided gradually. Edema of the lower limbs was treated with oral diuretics, lymphatic massage, and compression stockings. Consequently, the lower limb edema also improved. In this case, infection of a latent subcutaneous cyst in the thigh occurred and spread around the prosthesis due to leg edema, which was associated with loss of lower limb motion due to a calcaneal fracture. The presence of a potential thigh subcutaneous cyst is a risk factor for PJI. Moreover, lower extremity edema occurs by decreasing lower extremity motion, such as after a calcaneal fracture, and it increases the risk of extending extra-articular infection to the PJI. Potential thigh subcutaneous cysts and lower extremity edema are risk factors for the development of PJI. Orthopedic surgeons need to be aware of these facts during follow-up after TKA.","PeriodicalId":30287,"journal":{"name":"Case Reports in Orthopedics","volume":"2025 ","pages":"7710384"},"PeriodicalIF":0.4,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12045695/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144040139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current report is aimed at presenting a case of parosteal lipoma in a middle-aged female patient. Case Presentation: A 53-year-old diabetic lady presented with a gradually growing, painless mass in her right proximal forearm for the past 3 years. She complained of fatigue and reduced grip strength. The physical examination indicated a hard, immobile lump. A computed tomography scan revealed a clearly defined fat-density tumor with no bone involvement. Magnetic resonance imaging showed a well-defined fat-density mass surrounding most of the proximal radial shaft. The histological diagnosis of parosteal lipoma was made following surgical excision via Henry's approach. Literature Review: This minireview identified six reports on giant parosteal lipomas, involving patients aged adolescence to 83 years, mainly female. Common complaints were slowly progressive painless swellings. Imaging (radiographs, ultrasounds, CT, and MRI) revealed distinct features of lipomas. Surgical excision was the preferred management, with histopathology confirming lipoma diagnoses. Postoperative outcomes were positive, with no major complications or recurrences reported during follow-up. Conclusion: The tumor is a rare osseous neoplasm that may remain asymptomatic for years until it reaches a size capable of exerting pressure and causing motion difficulty. Meticulous care is paramount during surgical management to prevent iatrogenic nerve injury.","PeriodicalId":30287,"journal":{"name":"Case Reports in Orthopedics","volume":"2025 ","pages":"7750483"},"PeriodicalIF":0.4,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12008475/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144050085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metal-on-metal (MoM) THA implants were introduced two decades ago and subsequently recalled due to high early revision rates. Acetabular cup erosion and fragmentation secondary to chronic edge loading causing delayed instability are rare but devastating complications of MoM THA warranting expeditious revision surgery. Case Presentation: We report a 70-year-old male with a history of bilateral MoM THA who presented with left hip instability. In addition to the radiographic and clinical features of hip instability, macroscopic examination at revision surgery revealed extensive erosion and fragmentation of the antero-superior margin of the implanted cup, osteolysis, and widespread metallosis of the periarticular soft tissues. Discussion: This case highlights a significant adverse complication of MoM THA. Despite the industry's wide discontinuation and recall of these implants, MoM hip arthroplasty implants are present in many patients, who are all at risk of developing similar complications. Guidelines for the surveillance and treatment of both symptomatic and asymptomatic MoM THAs have been reported, although ambiguity remains in the optimal approach for managing patients with existing MoM THA. Conclusion: Failure of MoM hip arthroplasty is most commonly the result of adverse reaction to metal debris. We present a novel mechanism of failure in a patient presenting with late instability due to asymmetric wear of the MoM bearing surface.. While it is uncertain whether early intervention in this patient may have prevented this complication, arthroplasty surgeons should be aware of the various modes of failure for MoM hip implants, as expeditious revision surgery is often required.","PeriodicalId":30287,"journal":{"name":"Case Reports in Orthopedics","volume":"2025 ","pages":"3718607"},"PeriodicalIF":0.4,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11867716/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143524572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, achieving adequate curettage while minimizing damage to the articular cartilage is challenging. For lesions at the center of the distal femoral epiphysis, curettage using an intercondylar approach may have better oncological and functional outcomes than the conventional extra-articular approach from the wall of the epiphysis. We herein present a case of a 22-year-old male patient with a chondroblastoma of the femoral medial condyle close to the intercondylar fossa. Intercondylar curettage was performed at the site of the insertion of the posterior cruciate ligament (PCL). Maximal knee flexion allowed for good exposure of the lesion, and a direct approach to the tumor led to adequate curettage. Careful suturing of the PCL and postoperative care resulted in sufficient joint stability. The patient showed no signs of local recurrence or osteoarthritic changes at his 16-month follow-up. The intercondylar approach could be a surgical technique worth considering for the treatment of chondroblastoma in the distal femoral epiphysis, particularly for lesions located near the intercondylar fossa.","PeriodicalId":30287,"journal":{"name":"Case Reports in Orthopedics","volume":"2025 ","pages":"9978301"},"PeriodicalIF":0.4,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11870758/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143543865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
