Knee problems can result naturally over time due to minor sports injuries or improper stretching before strenuous activities. They can also result due to one specific incident causing a dislocation break, or strain. Knee replacement surgeries are somewhat rare but are over 90% successful although occasionally, problems can develop.
Minor problems which can occur after a knee replacement surgery can vary but some of the more common ones are creaking, squeaking, cracking, and popping noises. These are not out of the usual and will typically subside after a couple months of recovery. Once you are completely healed, if these sounds do not ease up, it’s important to contact the best knee doctor and set up a consultation.
A less common problem found with knee replacement surgeries is numbness around the incision or scar. This happens due to nerves supplying feeling to your skin are cut during the surgery. Some scars never gain feeling back but if they do, it could take up to two years to regain full feeling. Once two years have passed, the chance of gaining back feeling are slim to none.
Knee Surgery Risks
Along with the post-surgery side-effects, there are also many risks that go along with any type of surgery. Anesthesia could pose many risks such as adverse reactions to the medications or problems breathing. Many types of infections could also result as well as unwanted bleeding.
Additional Risks of Knee Surgery
• Blood Clots – This is one of the most problems associated with any type of surgery. Blood clots can be very dangerous, resulting in a possible heart attack or stroke.
• Swelling –The possibility of excess fluid building up around the knee joint is fairly high. Because of this, swelling can occur which can lead to fatigue and discomfort.
• Nerve Damage–If there is a wrong cut at any time, permanent blood vessel or nerve damage can occur. This will affect the sensation around the area where the nerve damage occurred.
• Complex Regional Pain Syndrome – The chances of CRPS happening are very rare but it is still a risk to be aware of. This affects circulation around the knee joint and will lead to pain and swelling. This can be treated but not cured.
• Long-Term Knee Problems – Knee replacement surgery is meant to fix current limitations you are facing but in rare cases, it could lead to more painful problems. One of the more common side-effects is trouble kneeling. You may not be able to kneel on that knee without feeling pain or you may need to use a cushion.
Long Term Knee Problems
Knee replacements are meant to last the rest of your life but often times, wearing will occur, especially if you are very active. Over 85% of knee replacements last for a minimum of 20 years. This does mean that there is a 15% chance your knee replacement will wear out in less than 20 years, creating the need for a second surgery. Loosening of the prosthesis also happens in 1.4% of patience which leads to a second total knee replacement. Lastly, even years after surgery the possibility of infection is possible. These are all potential problems when facing a knee surgery so consider consulting with the best knee doctor possible before your surgery.
