KNEE | LAS VEGAS
Dr. Andrew Lee, MD | Nevada Spine Clinic, Las Vegas, Nevada
The knee is the largest joint in the body, formed by the distal femur, the proximal tibia, and the patella. The articulating surfaces are covered with articular cartilage, and two C-shaped menisci provide additional cushioning and load distribution. The knee is stabilized by the cruciate and collateral ligaments and powered by the quadriceps and hamstring muscle groups.
When the articular cartilage wears away, the resulting bone-on-bone contact causes significant pain and limits mobility. Dr. Andrew Lee at Nevada Spine Clinic in Las Vegas evaluates each patient comprehensively before recommending knee replacement.
Dr. Andrew Lee at Nevada Spine Clinic in Las Vegas evaluates all knee patients for non-surgical options before recommending replacement. Physical therapy focused on quadriceps strengthening, anti-inflammatory medications, activity modification, bracing, and corticosteroid or hyaluronic acid injections are all considered.
Total knee arthroplasty is recommended when knee symptoms significantly limit daily function and quality of life despite adequate conservative management.
Total knee arthroplasty replaces all three knee compartments with metal and plastic components that resurface the damaged joint surfaces. Dr. Andrew Lee performs total knee replacement in Las Vegas at Southern Hills Hospital for patients with end-stage knee arthritis.
The arthritic surfaces of the distal femur, proximal tibia, and patella are precisely resurfaced with metal femoral and tibial components and a polyethylene tibial insert and patellar button. Component positioning is carefully planned and executed to restore normal knee alignment and ligament balance.
Modern total knee replacements are highly durable implants with excellent long-term outcomes. Most patients experience significant improvement in pain and function that is maintained for fifteen to twenty years or longer.
Walking with assistance begins on the day of surgery. Most patients are discharged within one to two days and transition to outpatient physical therapy.
Most patients achieve functional range of motion and independent ambulation by six weeks. Return to low-impact recreational activities typically occurs at three months.
Knee pain relief following total knee arthroplasty is typically significant, with most patients experiencing meaningful improvement within the first few weeks.
Some post-operative swelling and warmth around the knee is normal and may persist for several months. Physical therapy is essential for achieving the best range of motion and functional outcome.
No bathtub, swimming, or hot tub until cleared by Dr. Lee.
The knee incision is evaluated at your first post-operative visit. Avoid soaking the wound in water until cleared by Dr. Lee.
Blood clot prevention medication is prescribed following knee replacement and should be taken as directed. Pain medication refills require advance notice from your pharmacy.
Use the walker or cane as prescribed during early recovery. Avoid high-impact activities until Dr. Lee clears progressive return to function.
