Triathlon total knee replacement

A total knee replacement resurfaces the worn parts of the thigh bone and shin bone and may replace the underside of the kneecap. Triathlon is a named implant family; the surgeon chooses component sizes and fixation details for your anatomy and surgical plan. A metal component articulates with a polyethylene insert, creating a smoother bearing surface. Some designs use bone cement, while other fixation relies on bone growth around a component. Computer navigation may assist alignment, but it does not replace the surgeon’s judgement. Knee osteoarthritis is a common reason for considering this operation when pain and loss of function remain substantial.

Before surgery, review medicines, dental concerns, skin problems, and home support with your team. Afterward, expect a staged programme of walking, swelling control, strengthening, and range-of-motion work. Use the prescribed walking aid and exercises, protect the wound as instructed, and attend follow-up visits. Progress varies with fitness, other conditions, and the knee’s preoperative stiffness. Difficulty climbing stairs and knee pain often guide discussions about goals, but the operation is not a promise of unlimited activity or a particular result. Ask which implant materials and fixation method are planned.

Contact the surgical team for increasing wound redness, drainage, fever, worsening pain, or new difficulty bearing weight. Seek urgent help for sudden chest pain, severe breathlessness, or a painful swollen calf. A new loss of movement, instability, or a clicking sensation that is troubling should be assessed rather than ignored.

Ask why this implant system suits you, which components and fixation are planned, how navigation may be used, what activity limits apply, and how rehabilitation will be supervised.
