Partial knee replacement surgery is a surgical procedure for people whose knee joints are affected by osteoarthritis or another degenerative joint disease. This procedure is similar to a total knee replacement; however, in a partial knee replacement only part of the knee is replaced with an artificial implant.
Degenerative bone diseases such as osteoarthritis—which affects weight-bearing joints—cause significant pain and limit mobility. This happens because the cartilage that cushions these joints wears away, and doesn't provide the same level of shock absorption as it used to. If the joint becomes badly damaged, it may become necessary to replace the joint with an artificial one.
One option for surgical treatment is total knee replacement surgery, in which the entire knee joint is removed and replaced with an artificial joint implant. For some people, however their knee damage is confined to just one part of the joint, rather than affecting the entire joint. In these cases a partial knee replacement is a better option, because this surgery preserves those parts of the knee joint that haven't been damaged.
Both a partial and full knee replacement can significantly reduce pain and stiffness of the knee joint, and improve stability and range of motion. For several reasons, however, it's more desirable to have a partial knee replacement than a total knee replacement, if you're a good candidate for the surgery. For instance, partial knee replacement preserves more of the natural tissues of the joint, which means most people retain a better range of motion and better knee function afterwards. Another benefit is that recovery is faster after a partial knee replacement.
If you do have a partial knee replacement, you can still have a total knee replacement in the future if it ever becomes necessary.
In a partial knee replacement, the damaged parts of the patient's natural knee joint are replaced with an artificial implants. This surgery is usually performed under a general anaesthetic. However, if a patient is unable to tolerate a general anaesthetic they can have a local anaesthetic instead.
In a partial knee replacement procedure, the surgeon first prepares the implant site by removing the damaged cartilage and bone that needs to be replaced. Next, they put in place the mental implant that replaces the damaged portions of tissue. If necessary, they'll also “resurface” the kneecap. This improves the repaired joint's stability and flexibility. Finally, they insert a plastic device called a spacer, between the metal joint components. This ensures they glide against one another smoothly to allow the joint to move as freely as possible.
To prepare for surgery, a patient will undergo physical examinations to ensure they're a good candidate for the procedure, and to assess their overall general health. This is important to make sure that they don't have any medical conditions—such as high blood sugar or an infection—that might affect the safety of the procedure.
Another aspect of preparation is that certain medications make surgery more risky. These include blood thinners such as warfarin and non-steroidal non-inflammatory drugs, which increase the risk of excessive blood loss during surgery. People who take these medications are typically asked to stop for 10 to 14 days before their surgery to reduce the risk.
After the surgery is over there's usually a hospital stay of several days. Because partial knee replacement surgery is a less extensive procedure compared to total replacement, the recovery time tends to be a bit quicker. Most people can start to move their knee on the day after surgery, and find that their knee function returns quite quickly. However, it still takes several weeks of recovery time and rehabilitation exercises before it's safe to resume weight-bearing exercises.
I am writing to thanks you & your staff fro the wonderful work you did on my hip repllacement. It is so nice not to be in constant pain and it's enjoy able to go for a walk now & not dread it as before. I can't thank you + the staff at the cavell hospital enough.
After years of arthritic pain, steroid injections, physiotherapy and arthroscopy (which actually made things far worse)... I now feel like a new woman thanks to the knee surgery you performed last month - I have no doubt this is due in no small part to your skill as a surgeon. The wound healed quickly, recovery has been rapid, without any complications and the scar is neat and beautifully stitched!!
Having recently undergone a full left knee replacement I am 100% satisfied with everything Mr Saksena and his team at The Cavell provided. I was given plenty of advice both before and after my surgery, which was very reassuring. My recovery has been rapid with minimal pain and within 8 weeks I had full extension and 130 degree flexion back in the knee. I wouldn't hesitate to recommend Mr Saksena as an orthopaedic surgeon.
I had a total knee replacement with Valgus Deformity 7 weeks ago, and this gave the surgeon extra work to do, I only have good things to say about this surgery and after care with all staff involved at Chase Farm Hospital, as in my experience I have heard a lot of good and bad things about this type of surgery, Well I can only say that if anyone has concerns about this please try not to worry it is worth while as it has given me a new lease of life to what I had before, and yes the first 2 weeks are the worse, but please do try your exercises, because as they say you only get the real benefit if you are prepared to do your bit. Thanks very much for my new lease of life yet again.
I was very fortunate to be referred to Mr Saksena as an NHS patient and was very impressed with the treatment and care provided by Mr Saksena and the whole team at Cavell Hospital. Once discharged, someone was always available to talk to you and an appointment was made immediately if you needed to see a nurse (which I did several times, due to a normal discharge from my wound). The entire staff were all friendly, cheerful and efficient. The scar is very neat and after 7 weeks I am walking well and just using a stick outdoors.
I would like to just sincerely thank you for the job you did on my knees, both of them. Before I had my knees replaced I was in constant pain, which had been the case for nearly 5 years. It was so bad that I often wondered what the use was in living! Now, nearly 2 years later, I feel I have my life back. I can now walk without pain and every single day, and I mean every single day, I walk the roads that I walked pre-operations and I remember the pain that I was in for every small distance I had to walk. Now, I walk with a smile on my face and a thrill in my heart, so very grateful for having the freedom to enjoy walking once again. I also have great fun going with the grandchildren to the park and playing with them, which before the operation was impossible as all I could do was basically sit and supervise them. So there too there is a huge change.
You did a total knee replacement on my right leg on 22nd March in the Kings Oak Hospital and it has been very successful. I am now almost pain free with the knee getting stronger each day. I would like to thank you and your excellent medical team for doing such a neat job. I would also like to thank the wonderful nurses at the hospital who were always cheerful and efficient.
In September 2014 I underwent a knee replacement operation. Mr Saksensa was an amiable professional with a calming influence and caring nature. His team were friendly and supportive. My knee replacement was a complete success and I am still enjoying my favourite sport of skiing.
You performed a partial meniscectomy at Highgate Hospital in late april. I would like to thank you for your hardwork; the problem has been entirely resolved and I am pretty sure that is down to the procedure rather than the passage of time as the condition persisted during the prior two months. Some part of that is surely down to your skill.
