Purpose of the Study:

• To critically evaluate the roles of inflammatory and mechanical factors in osteoarthritis pathogenesis.
• To address the ongoing debate regarding the terminology of osteoarthritis versus osteoarthrosis.
• To synthesize current literature on the multifactorial etiology of OA.

Main Methods:

• Literature review and synthesis of existing research.
• Analysis of studies investigating inflammatory mediators in OA.
• Examination of biomechanical and mechanical stress factors in OA.

Main Results:

• Growing evidence supports the significant influence of inflammatory processes in OA onset and progression.
• The distinction between "osteoarthritis" (implying inflammation) and "osteoarthrosis" (implying degeneration) reflects a key debate.
• Both inflammatory and mechanical factors likely contribute to OA pathogenesis, but their relative importance is under investigation.

Conclusions:

• The pathogenesis of osteoarthritis is complex and multifactorial, involving both inflammatory and mechanical components.
• Further research is needed to fully elucidate the interplay between inflammation and mechanical stress in OA.
• Clarifying the terminology and understanding the precise mechanisms are crucial for effective OA management.
