As an orthopedic surgeon specializing in knee joint procedures in Afghanistan, I am interested in your total knee arthroplasty (TKA) products. Specifically, I am looking for pricing information on primary TKA components, including femoral and tibial components, as well as your revision systems such as CCK and hinge options. Could you provide me with your current pricing for these products? Additionally, it would be helpful to know about any available bulk purchase options or special offers you may have. I'm looking forward to your prompt response to facilitate my decision-making process.
