ABSTRACT

One of the main causes of pain, incapacity, and decreased mobility in the elderly is osteoarthritis (OA) of the knee. When conservative approaches fail, total knee replacement (TKR), which provides pain relief and increased function, is regarded as the final solution. This case series presents seven elderly patients with advanced knee OA who underwent cemented posterior-stabilized TKR. Patients commonly presented with chronic pain, varus deformity, and functional limitations, often complicated by comorbidities such as HTN, CKD & Parkinson’s disease. Intra-operative outcomes across all cases demonstrated stable implant fixation and satisfactory patellar tracking. Postoperative rehabilitation varied depending on individual patient factors, with early mobilization recommended in most cases, though physiotherapy initiation was delayed in some due to wound-related concerns. Despite these variations, all patients achieved favorable short-term recovery without major complications. This series emphasizes that TKR remains a safe and effective option for elderly individuals, even with systemic comorbidities, provided careful preoperative planning and individualized rehabilitation are ensured. To confirm these results and improve rehabilitation tactics, larger trials with longer follow-up are needed.
