Purpose: Flexion instability following total knee arthroplasty (TKA) is a common indication of early revision. The association between the objective anteroposterior (AP) laxity direction in mid-range flexion and the subjective healing of instability remains unclear; thus, this study aimed to clarify this association.
Methods: In this study, 110 knees (74 females, 92 knees; 16 males, 18 knees) with medial pivot implants were examined with a median age of 79 (range 60-92) years for a median follow-up duration of 22 (range 6-125) months.
Article Synopsis
- The study examines the relationship between knee malalignment (specifically varus alignment) and the development of knee osteoarthritis (OA), focusing on changes in the proximal tibia.
- Involved 736 knees from 390 women over two surveys conducted between 1979 and 2000, initially without radiographic knee OA.
- Findings indicate that a greater tibial plateau angle and increased medial tibial cortical bone thickness are associated with higher odds of developing advanced knee OA, suggesting that varus alignment may have a role in early morphological changes leading to OA.
