Eighty-four cementless primary total knee arthroplasties were performed from June 1989 to May 1993, and the prevalence and characteristics of osteolysis were determined after a mean follow-up of 6.4 years(range, 5 to 8.1 years). Eighteen knees(21.4%) were identified as being associated with osteolysis, and the incidence of osteolysis was 10,7% for the femur and 13.1% for the tibia. Osteolysis was first noted radiographically at an average postoperative 4.7 years(range, 2.5 to 8, i years). Osteolysis of the femur was identified adjacent to the nonporous-coated regions of the anterior and posterior flanges of the components, The medial screw was more frequently associated with osteolytic lesion than the lateral one. Ten(55.6%) of the 18 prostheses were revised, 5 for advanced polyethylene wear, 3 for failed tibia1 fixation, and 2 for severe osteolysis. Significant factors associated with osteolysis were increased body weight(p<0.05) and malalignment(p<0.05). Femoral osteolysis was more common in Ortholoc design(20.0%) than in AMK design(4.1%). The AMK prosthesis(16.3%) showed higher in an incidence of screw osteolysis and tibial osteolysis than Ortholoc prosthesis(8.6%). The nonporous-coated flanges of the components and the polyethylene locking mechanism may be responsible for the differences in the incidence and region of osteolysis.

Purpose: The purpose of this study was to evaluate the factors that have an influence on the osteolysis of cementless acetabular components (Harris-Galante type 2). Material and Method: From 1991 to 1994, 36 patients (44 cases) of total hip arthroplasty using a Multilock femoral stem and a Harris-Galante type 2 acetabular cup were reviewed with minimal follow-up period of 10 years. The relationship between the osteolysis and several factors such as the age, gender, weight, etiology, inclination, polyethylene liner thickness and wear rate were analyzed. Results: Osteolysis around the acetabular cup was found in 18 cases (40.9%). The most common area where this developed was zone 2 (16 cases, 36.4%). There was no statistically significant relationship between the age, gender, weight, etiology, inclination angle and the osteolysis. However, there was statistically significant correlation between the polyethylene liner thickness, wear rate and osteolysis. The average polyethylene liner thickness was 7.1 mm in cases with osteolysis and 8.1 mm in cases without osteolysis. The average wear rate was 0.26 mm/year in the osteolysis group, and 0.14 mm/year in the non-osteolysis group. Conclusion: The incidence of osteolysis in the cementless acetabular component (Harris-Galante type 2) may increase as the follow-up period increases, and it was significantly related to the thickness and wear rate of the polyethylene liner. We suggest that the acetabular component needs an improved locking mechanism, improvement for the polyethylene liner longevity, and a ceramic or metal bearing surface is needed.

There are many investigations about the femoral osteolysis including the patterns and size of the lesion. However, the factors, which influence the patterns and size of the femoral osteolysis, are not well known. Purposes of the study were to evaluate the patterns of the femoral osteolysis, to analyze the planimetric and approximate volumetric values of the lesion after cementless total hip arthroplasty and to evaluate the factors, which influence the patterns and size of the femoral osteolysis. We analyzed 120 hips who had undergone cementless THA using Harris Galante pomus prosthesis (Zimmer, Warsaw, Indiana) in 49 hips and Anatomic components (Zimmer, Warsaw, Indiana) in 71 hips. After an average of 4.9 years (range 4-10 years), 45 cases (37.5%) showed femoral osteolysis on the radiograph. The mean rate of linear wear was 0.24+-0.14mm in the cases of the femoral osteolysis. The size of the femoral osteolysis was correlated with duration, stem type, linear wear amount and linear wear rate. The linear wear amount showed higher correlation than the linear wear rate. In this study, the factors which influence the patterns of the femoral osteolysis were not found. Among eight cases of the revision, five cases required the revision due to severe femoral osteolysis lesion and polyethylene liner wear without the loosening of the prosthesis. We could confum that the size of osteolysis is important factor for the result of THA. Therefore, it is necessary to carefully follow-up the patients which show the osteolytic lesion and include the size of osteolysis in the item of the evaluation for the result of THA.

Purpose: We wanted to measure the size of the osteolysis of the pelvis and to quantify its location and we wanted to assess the correlation of these measurements with the clinical result. Materials and methods: We evaluated 40 hips (31 patients) that showed definitive osteolysis among 116 hips (97 patients) that underwent 3 dimensional CT scanning post-operatively after total hip arthroplasties with using cementless acetabular cups. The inclusion criteria were a follow up duration of more than 18 months and no history of infection. The radiographs were obtained at the 6th to 12th week postoperatively. The size of pelvic osteolysis was divided into 4 groups (less than 1 cm3 (A), between 1 cm3 to 2 cm3 (B), between 2 cm3 to 3 cm3 (C), more than 3 cm3 (D)), and the location of osteolysis was divided into 5 groups (anterior, posterior, superior, inferior and central) The size and location of osteolysis and the wear of the polyethylene were analysed in relation to the clinical outcome, which was assessed using the Harris Hip Score). Results: The average size of the osteolysis was 3.2 cm3 (A 14 cases in group A, B 11 cases in group B, C 4 cases in group C, and D 11 cases in group D). There was significant correlation between the size of the osteolysis and the clinical outcome (Rs=-0569). However, there was no significant correlation between the osteolysis location (Anterior: 18 cases, Superior: 5 cases, Posterior: 10 cases, Inferior: 33 cases and Central: 32 cases) and the clinical outcome (P=0.35). Conclusion: There is a significant correlation between the size of the osteolysis and the Harris Hip Score (Rs=-0569). Especially, a pelvic osteolysis of more than 3 cm3 was found to be correlated with a decreased postoperative HHS (P=0.022). We hope that these results may be useful to help guide the treatment of osteolysis.

LIM Homeobox Transcription Factor 1-β Expression is Upregulated in Patients with Osteolysis after Total Ankle Arthroplasty and Inhibits Receptor Activator of Nuclear Factor-κB Ligand-Induced Osteoclast Differentiation in Vitro

Background: Osteolysis is one of the most common problems that occurs after total hip and knee arthroplasty and has recently become a significant problem after total ankle arthroplasty (TAA). In this study, we investigated the role of LIM homeobox transcription factor 1-β (Lmx1b) in osteoclast differentiation. By evaluating the expression profiles as- sociated with osteolysis following TAA treatment, Lmx1b was found to be differentially expressed in patients with osteolysis after TAA. Methods: To identify the important genes associated with osteolysis after TAA, RNA sequencing was performed by analyzing 8 pa- tient samples: 5 primary TAA samples (control group) and 3 TAA samples revised for flex- ion instability (osteolysis group). By analyzing the differentially expressed genes and gene ontologies, Lmx1b expression was found to be upregulated in the osteolysis group compared to that in the control group. Focusing on the role of Lmx1b in bone cells, Lmx1b was overexpressed by a retrovirus in osteoclast precursor cells. The cultured cells were stained with tartrate-resistant acid phosphatase, and the expression of osteoclast- related genes was analyzed using real-time polymerase chain reaction. Results: Lmx1b overexpression in osteoclast precursors suppresses osteoclast formation and resorptive activity. The expression of osteoclast marker genes was significantly reduced during os- teoclast differentiation by Lmx1b overexpression. Furthermore, Lmx1b is associated with nuclear factor of activated T cells 1 (NFATc1) and inhibited NFATc1 translocation into the nucleus. Conclusions: These results provide novel insights into the anti-bone resorp- tive effect of Lmx1b on osteolysis after TAA and may lead to the development of effec- tive preventative and therapeutic strategies for peri-implant osteolysis.

Background and Objectives: The biologic reaction to particulate wear debris had implicated as a causative factor in periprosthetic osteolysis following total joint arthroplasty. It has been suggested that the prevalence, location and severity of osteolytic defects is related to several factors including access of wear particules generated at the articulation to the implant-bone interface. The purpose of this study was to examine the inflence of femoral component design on the location and prevalence of diaphyseal osteolysis. Materials and Methods: 101 patient (119 hips) who had had a Harris-Galante (HG) total hip arthroplasty (THA) were matched by age, weight, sex, and diagnosis, with 100 patients (122 hips) who had had a Multilock THA X-rays were reviewed and the location of osteolytic lesions were noted using Gruen's zonal analysis. Results: In the HG group, the overall prevalence of femoral osteolysis was 47%(56/119). Among the 38 of the 56 cases in the HG group with osteolysis, the lesions were in Gruen zones 3, 4 and 5 around the distal protions of the stem. In contrast, no diaphyseal osteolysis was noted in the Multilock group at comparable length of follow up (p<0.05). In the HG group, 7 patients had required femoral revisions for progressive femoral osteolysis. None of the Multilock stems required revision surgery. Histologic examination of the tissue from the osteolytic areas demonstrated a characteristic foreign body granuloma with particulate polyethylene noted in all cases. Conclusion: The presence of polyethylene in the osteolytic defects around the distal portion of the stem supports the concept of the effective joint space as this material obviously came from the hip articulation. The significant difference in diaphyseal osteolysis comparing the HG and Multilock stems at comparable follow-up times lends credence to the gasket theory. Based on this data, it does appear that circumferential porous coatings arc a relative barrier to the ingress of at least clinically significant amounts of wear debris generated at the hip articulation. Incomplete or patch porous coatings are like to provide a conduit for wear particles to gain access ot the implant-bone interface.

Purpose: We analyzed and compared 30 clinical cases of acetabular osteolysis around a stably fixed acetabular cup, and this was managed by changing the liner along with retaining or revising the cup. Materials and Methods: We analyzed 30 patients who underwent acetabular component revision or retention with a bone graft for osteolysis around a stably fixed Harris-Galante acetabular cup and these patients were followed up for more than 2 years. There were 7 cases with a conserved the acetabular cup and only the liner was changed, and 23 cases with a totally revised acetabular component. We compared the size of the acetabular cup, the thickness of the polyethylene liner, the progression of osteolysis and the clinical outcomes. Results: The Harris hip score was improved in both groups. In the retention group, during an average of 59.9 months of follow up, 7 cases showed stable fixation and 3 cases showed locally advanced osteolysis. In the revision group, during an average of 57.2 months of follow up, all 20 cementless acetabular cups showed stable fixation. Conclusion: We suggest that in patients with osteolysis around the stable cementless acetabular cup, both methods show satisfactory clinical outcomes. But considering recurrence of osteolysis, cup revision is more reliable than changing the liner with a bone graft.

Periprosthetic osteolysis may be the most common cause of late failure after total hip arthroplasty perfomed without cement and its incidence is increasing with time. The purpose of this study was to find out the incidence and the characters of the periprosthetic osteolysis and to analyse its relation with the possible factors; age, sex, body weight, size of the acetabular cup or the femoral stem, stability of the femoral stem, and clinical score. The authors analysed twenty-one cases in eighteen patients of bipolar hemiarthroplasty and twenty-eight cases in twenty-five patients of total hip arthroplasty inserted with non-circumferential porous coated femoral stem of Harris-Galante type and femoral head of 28 millimeter diameter from Jan. 1985 to Dec. 1991. All of the patients were followed up for at least four years. The results obtained were as follows: l. Over all incidence of periprosthetic osteolysis was 38% in bipolar hemiarthroplasty and 35.7% in total hip arthroplasty. 2. The pattern of osteolysis in bipolar hemiarthroplasty was 3 focal, 4 multifocal and 1 diffuse osteolysis, and in total hip arthroplasty, 3 focal, 4 multifocal, and 3 diffuse osteolysis.

Cervical Myelopathy Induced by Posterior Vertebral Body Osteolysis after Cervical Disc Arthroplasty

Man Kyu Choi,Jun Ho Lee 대한신경외과학회 2023 Journal of Korean neurosurgical society Vol.66 No.5

Cervical disc arthroplasty (CDA) has become more widespread and diverges from the conventional technique used in anterior cervical fusion for cervical degenerative disc disease. As arthroplasty has become a popular treatment option, few complications have been reported in the literature. These include subsidence, expulsion, posterior avulsion fractures, heterotopic ossification, and osteolysis. One of the critical complications is osteolysis, but current studies on this subject are limited in terms of not elucidating the incidence, etiology, and consequences. The authors present two cases, who presented with clinical signs of gradually worsening myelopathy induced by posterior vertebral body osteolysis, 2 years after CDA. Subsequently, the patient underwent posterior decompression and fusion without prosthesis removal. Postoperatively, the clinical symptoms gradually resolved, with no severe deficits. The present rare cases highlight the osteolysis that occurs after CDA, which can cause cervical myelopathy, and suggest spine surgeons to be alert to this fatal complication.
