Osteoarthritis
Osteoarthritis is a degenerative joint disease where the cartilage cushioning the joints gradually wears away, leading to pain, stiffness, and decreased mobility. It most commonly affects weight-bearing joints like the knees, hips, and spine. As the condition progresses, bones may rub against each other, causing inflammation and further damage. Risk factors include age, obesity, prior injuries, and genetics. Early treatment focuses on pain management and physical therapy. In advanced stages, joint replacement surgery, such as knee or hip arthroplasty, may be recommended to restore function and relieve pain, offering patients improved mobility and quality of life.
Rheumatoid Arthritis
Rheumatoid arthritis is an autoimmune disease where the immune system mistakenly attacks the joints, causing chronic inflammation. Unlike osteoarthritis, which results from wear and tear, rheumatoid arthritis affects the joint lining, leading to swelling, pain, and joint deformities over time. It typically starts in small joints like those in the hands and feet but can progress to larger joints, including hips and knees. Joint damage is often irreversible, so early diagnosis and treatment are crucial. Medications, lifestyle modifications, and physical therapy can slow progression. In severe cases, joint replacement may be necessary to reduce pain and restore function.
Avascular Necrosis (AVN)
Avascular necrosis (AVN) is a condition where the blood supply to a bone is disrupted, leading to bone tissue death. It most commonly affects the hip joint, especially the femoral head. Causes include trauma, long-term steroid use, excessive alcohol consumption, and certain medical conditions. Symptoms include joint pain, stiffness, and limited range of motion. In early stages, conservative treatments like medication and reduced weight-bearing may help. However, if the bone collapses or joint damage occurs, surgical options such as core decompression or total joint replacement become necessary. Early detection is critical to prevent joint collapse and disability.
Post-Traumatic Arthritis
Post-traumatic arthritis occurs after a joint injury, such as a fracture, dislocation, or ligament tear. The trauma damages the cartilage or alters joint mechanics, leading to accelerated wear and inflammation. This condition can affect any joint but is common in the knee, ankle, and hip. Symptoms include joint pain, stiffness, swelling, and reduced mobility. It may take years after the initial injury for arthritis to develop. Treatment options include anti-inflammatory medications, physical therapy, lifestyle changes, and in advanced cases, surgical interventions like joint replacement to relieve pain and improve function.
Failed Joint Replacement (Revision Surgery)
A failed joint replacement occurs when a previously implanted joint prosthesis no longer functions properly due to wear, loosening, infection, or mechanical failure. Patients may experience pain, instability, swelling, or reduced mobility. Causes include implant wear over time, bone loss, infection, or improper alignment. Diagnosis involves imaging, lab tests, and clinical evaluation. Treatment usually requires revision joint replacement surgery, where the old implant is removed and replaced with a new one. Revision surgeries are more complex than primary replacements and require specialized planning and surgical expertise to restore joint function and reduce complications.
