Its avascular necrosis of hip joint
⠀
⏩Avascular necrosis is characterized by osseous cell death due to vascular compromise. ⠀
⠀
⏩Avascular necrosis of bone results generally from corticosteroid use, trauma, SLE, pancreatitis, alcoholism, gout, radiation, sickle cell disease, infiltrative diseases (e.g. Gaucher’s disease), and Caisson disease. ⠀
⠀
⏩The most commonly affected site is the femoral head and patient’s usually present with hip and referred knee pain. ⠀
⠀
⏩Radiological features of osteonecrosis generally involve collapse of the articular cortex, fragmentation, mottled trabecular pattern, sclerosis, subchondral cysts, and/or subchondral fracture.⠀
⠀
⏩A bone-scan or MRI could also be used to confirm the presence and extent of avascular necrosis.⠀
⠀
⏩Treatment is mainly surgical and generally involves a total hip replacement or arthroplasty for end-stage femoral head osteonecrosis using either a cemented or cementless prosthesis.⠀
⠀
⏩ Cemented total hip arthroplasties have been reported as being inferior with high failure rates in younger patients and in patients with femoral head necrosis because of their inferior durability. ⠀
⠀
⏩Improved outcomes have been reported with cementless total hip arthroplasties for patients with femoral head osteonecrosis.⠀
⠀
⏩Rehabilitation treatment protocols vary widely after total joint replacement. ✅presurgical exercise program may be beneficial in increasing the rate of improvement in patient recovery after a total hip replacement. Early mobilization is the gold standard in restoring functional mobility after total joint arthroplasty.

Mouse embryonic fibroblasts stained for cytoskeletal actin (red), and the actin binding proteins tropomyosin (green) and myosin light chain (blue). Proteins that decorate actin filaments often bind in a striated manner rather than in a continuous network along the fiber.
