Abstract

Objective: Medial meniscus tear (MMT) is a common method to induce osteoarthritis in rats, but mimics secondary osteoarthritis. A novel method of carrying out a medial wedge closing tibial osteotomy (TO) has been recently developed to induce primary osteoarthritis. This study aims to validate it, compared to MMT.

Methods: Twenty rats were divided equally into 2 groups. Outcome measures such as histology graded according to Osteoarthritis Research Society International (OARSI) guidelines and computed tomography (CT) scans were analyzed at 6 weeks post-operatively. Observational gait analysis and serum biomarkers such as C-terminal cross-linked telopeptides of type II collagen (CTX-II) and interleukin-1 beta (IL-1β) were collected at 2-weekly intervals up to 6 weeks post-operatively.

Results: Serum CTX-II and IL-1β levels did not reveal a statistically significant difference across all time points between the 2 groups. CT grading was significantly more severe (2.80 ± 1.10 vs 1.40 ± 0.548, P = 0.0389) in the MMT group compared to the TO group. In addition, histological gradings such as calcified cartilage score (2.10 ± 1.91 vs 0.00 ± 0.00, P < 0.01) and cartilage degeneration score (4.80 ± 5.18 vs 0.00 ± 0.00, P < 0.01) revealed significantly more severe osteoarthritis in the MMT compared to TO group. Synovial membrane score did not reveal a statistically significant difference (1.10 ± 0.994 vs 1.00 ± 0.00, P = 1.00).

Conclusion: TO is a novel method in inducing primary osteoarthritis in the rat model compared to MMT between the 6 and 12 weeks' time frame.

大鼠内侧半月板撕裂与胫骨截骨致早期膝关节骨关节炎模型的比较。

目的：内侧半月板撕裂（MMT）是诱导大鼠骨关节炎的常用方法，但模拟了继发性骨关节炎。胫骨内侧楔形截骨术（TO）是一种治疗原发性骨关节炎的新方法。与MMT相比，本研究旨在验证它。方法：将20只大鼠随机分为2组。结果测量，如根据国际骨关节炎研究协会（OARSI）指南的组织学分级和术后6周的计算机断层扫描（CT）扫描进行分析。观察性步态分析和血清生物标志物，如II型胶原c端交联末端肽（CTX-II）和白细胞介素-1β (IL-1β)，每2周至术后6周收集一次。结果：两组患者血清CTX-II和IL-1β水平在各时间点间差异无统计学意义。MMT组CT分级明显高于to组（2.80±1.10 vs 1.40±0.548,P = 0.0389）。此外，组织学分级如软骨钙化评分（2.10±1.91 vs 0.00±0.00,P < 0.01）和软骨退变评分（4.80±5.18 vs 0.00±0.00,P < 0.01）显示MMT组骨关节炎的严重程度明显高于to组。滑膜评分差异无统计学意义（1.10±0.994 vs 1.00±0.00,P = 1.00）。结论：与MMT相比，TO在6 ~ 12周的时间内诱导大鼠原发性骨关节炎是一种新的方法。

期刊介绍： CARTILAGE publishes articles related to the musculoskeletal system with particular attention to cartilage repair, development, function, degeneration, transplantation, and rehabilitation. The journal is a forum for the exchange of ideas for the many types of researchers and clinicians involved in cartilage biology and repair. A primary objective of CARTILAGE is to foster the cross-fertilization of the findings between clinical and basic sciences throughout the various disciplines involved in cartilage repair. The journal publishes full length original manuscripts on all types of cartilage including articular, nasal, auricular, tracheal/bronchial, and intervertebral disc fibrocartilage. Manuscripts on clinical and laboratory research are welcome. Review articles, editorials, and letters are also encouraged. The ICRS envisages CARTILAGE as a forum for the exchange of knowledge among clinicians, scientists, patients, and researchers. The International Cartilage Repair Society (ICRS) is dedicated to promotion, encouragement, and distribution of fundamental and applied research of cartilage in order to permit a better knowledge of function and dysfunction of articular cartilage and its repair.
