Superb Orthopaedic Surgeon by Grateful Patient Dr. Lent operated on my knee and I am thankful for his remarkably skillful expertise. He extended care beyond all expectations. I feel great relief because of the care he extended to me. Thank you, Dr. Lent for being a great doctor and surgeon!


left hand carpal tunnel surgery

I'm very grateful for all the staff at the Southern Westchester Orthopedics and to the stall at St John's Riverside Hospital. Dr. Lent who's a great doctor, referred me to Dr. Spencer his partner who a Hand Specialist . We spoke of my concerns regarding surgery but he assured me that everything would turn out ok . I'm telling you that from the moment I woke up, I felt a difference in my hand. No more pain. Wow. Thank you very much for being a great doctor and a caring person.


Knee replacement

Dr. Lent worked wonders for me. I had a partial knee replacement and within weeks I was up and walking without support. My physical Therapy went great. I will definitely go back to him to have my other knee replacement. Thanks Dr. Lent


Total Knee Replacement

I have been a patient of Dr. Lent's for several years now. Two years ago I had a total knee replacement done by him, and more recently a surgery on my rotator cuff. He is the most understanding doctor I have ever dealt with. Before the operation I saw him in his office where he explained the entire procedure to me. This comforted me before my surgery. I recommend him to everyone who is having problems with their knees or any other orthopedic issue. I would not be walking the way I am today if it wasn't for him. Thank you very much Dr. Lent.


partial knee replacement

Dr. Lent came highly recommended by a friend who had the same problem as I and had the MAKOplasty surgery. My surgery was only six days ago and already I am doing very well. Although I am still using a cane part of the time, I am able to walk on my own. While my friends waited for the surgery to be over they met Dr. Lent and he was friendly, patient and informative. I had a great deal of faith that things would go well and I have even more faith in Dr. Lent now. If I should ever need further orthopedic surgery, though I hope not, I would certainly come to him.


ganglion cyst

The staff at SWO&SM are the nicest, most down to earth people I have met. The front desk girls are always pleasant, helpful and informative. The surgery scheduling girls are terrific. they talk and write out everything as well as explaining any and all inquiries. The X-Ray techs are also so friendly and really show that they care. The atmosphere in this office creates a truly pleasant experience and it shows why these doctors are so understanding, caring and excellent at what they do. Dr. Spencer is the best!!!


Total Knee Replacement

This past May I had a total knee replacement done by Dr. Edelson, Dr. Spencer and Andrew Kirk, PA. I had been putting off getting the surgery for awhile, as I had heard so many stories of how painful and difficult the recovery process was. Though I intended to keep pushing off the surgery, my knee chose otherwise. One night I was awakened by a painful and dysfunctional knee. I had my surgery done in St John's Hospital. My experience there was wonderful - caring staff, excellent physical therapy, and more aware of my needs than I was. I returned to work after 5 short weeks with a new knee that I am so grateful to have. The doctors at Southern Westchester Orthopedics were so very good to me and calmed my fears - excellent job!



As a former Athletic Director and current Assistant Principal in the City of Yonkers, I have had many athletes injured during athletic practices and contests over the last past years. Dr. Lent has been kind enough to treat me for most of them. When you work in a school environment, injuries take place on a daily basis. As an Administrator, you must trust in the care that is provided to your students when they sustain a serious injury. Dr. Lent has been there to care for my athletes over the last 14 years. He and his staff have diagnosed my athletes injuries and worked with them throughout the healing process. I highly recommend his services to anyone who has sustained a severe injury and is looking for a highly effective physician that cares and takes his job seriously. You are in good hands with Dr. Lent and his staff.


Partial knee replacement Mako Plasty

I had the Mako Plasty surgery on October 1, 2013 performed by Dr. Lent. 2013. I was up and walking within 2 weeks, without the support of a cane or a walker. I returned to work in 5 short weeks and it was the best thing I could have ever done. I would highly recommend it to any one who is doubting it. As a matter of fact I have to go and get my other knee done, and I wouldn't choose any doctor other than Dr. Lent.


Knee replacement

Dr. Lent operated on my knee and I am thankful for his expertise. Dr. Lent is a great doctor and surgeon! He got me back on my feet, and back to work, in only two months! Louis Loizou, grateful patient


MAKOplasty- Knee Resurfacing and Replacement

I have been a patient of Dr. Lent's for the past 10 years. I had cartilage surgery about 9 years ago and at the time Dr. Lent informed me that I will need a full knee replacement in the future and that I will know when the right time for this will come. I held off as long as possible out of the fear of hearing horror stories from friends who had knee replacement surgery from other doctors. They had bad experiences with the pain and healing process. My pain was increasing over the past year and continued until the point where it was constant every day. On Dec. 2, 2013, I knew the time had come. I had an appointment with Dr. Lent and after an MRI and Xrays, he confirmed that I was a perfect candidate for MAKOplasty Knee surgery. His kindness, caring and informative information about this surgery made me comfortable and I agreed to proceed with MAKOplasty. On Dec. 18th. I had the surgery and it went extremely well. St. John's Hospital staff were wonderful, attentive and kind. I was released the next day because I was able to walk around with a walker. I did not have to go to rehab. I went straight home. PT and a visiting nurse came to my house several times. I was walking with only a cane after 3 days, and was able to enjoy the Holidays with my family. Just about 2 weeks have gone by and everyone is amazed with my progress. I am walking without a walker or cane. Office visit with Dr. Lent today (12/30) and he was very happy with my recovery, healing and cannot believe that I am walking on my own. I am so confident about this procedure and Dr. Lent That I am ready to have my other knee done in a couple of months. I would recommend any body that needs a full knee replacement to see Dr. Lent for an consultation to confirm that they are a candidate for MAKOplasty Knee resurfacing/Replacement. I cannot express my gratitude and confidence in Dr. Lent for such a remarkable outcome. A very Happy Patient, Andrew Young.



I met Dr. Lent many years ago. Dr. Lent operated on my rotator cuff, meniscus repair and broken wrist. Each time I recovered successfully and quickly. I recently moved to Rockland County and went to an orthopedic doctor there. I was told that I needed a complete knee replacement. In the meantime I was listening to the radio while driving and heard Dr. Lent talking about Makoplasty. A friend from Yonkers sent me a clipping on his procedure from the Journal News. I called and made an appointment for a consultation. Dr. Lent informed me that I was a candidate for the Makoplasty. I set up a date for the surgery. On August 30, 2013 I had surgery done on my left knee. My previous limp leg was now straight and functional. By December, I was back on the tennis court. THANKS DR. LENT


partial Knee replacement

This was the best thing I could have done, It took me many years to come to this conclusion, The only regret is that mako was not around sooner, Dr Lent did an outstanding job on my knee, I highly recommend this procedure, it makes a great difference


Makoploasty Right Knee

Best decision I ever made going to Dr. Lent. From the initial consultation to my surgery everyone I came in contact with was professional and caring. I was up and walking in days and after some physical therapy it felt like I had been given a new pain free life. Dr. Lent is the best.


partial knee replacement

I have a new life. No more limping. No more pain! I was walking in a few days. Dr. Spencer and the staff at Southern Westchester Orthopedics opened a new door for me. I cant thank Dr. Spencer enough!!!


Makoplasty surgery

Dr. Lent did a MAKOplasty partial knee replacement three months ago on me --- I am amazed at how great my knee feels. I never thought I would be pain-free again. I suffered for years with constant pain and aches in my knee. The surgery was unbelievably easy - I actually walked out of the hospital 48 hours after the surgery. St. John's Riverside hospital was fantastic. The staff was very attentive, and the rooms were immaculate. I was skeptical to write this review too soon -- so I waited to see how I felt a few months later. My knee has progressively felt better and better. I have stability, no pain - and I can sleep at night painfree! Thank you so much, Dr. Lent! At 54 years of age, I feel like I have a twenty year old knee. I wish my other knee felt as strong as my new knee does. I will probably return to have the other one done.


Partial Knee Resurfacing

I recently had a partial knee replacement conducted by Dr. David Lent at St. John's Riverside Hospital. I am currently undergoing physical therapy three times per week and feeling better everyday. A big thank you to Dr. Lent and the physical therapy team at Southern Westchester Orthopedics!!!!


Carpel Tunnel Surgery

I would like to thank Dr. Eric M. Spencer and his complete staff for the splendid job they did in arranging both my carpel tunnel surgeries, first back in July 2013 for one arm and the other this August 2014. I am deeply appreciative of the attention to detail in completing all the paperwork that was necessary for my workman's compensation. The staff was very professional and made the whole process easy for me. I'm finally pain free and highly recommend the Southern Westchester Orthopedics & Sports Medicine office and group of doctors. They are 2nd to none. Thank you again!


Knee Surgery

I had arthroscopic surgery on my right knee to repair a torn meniscus on August 12, 2014 . I was pleasantly surprised with the results. Immediately after the surgery, I could bed my knee fully and I was able plant my foot flat on the floor. Shin a very short time I was walking normally. The BEST part was that I had no pain, a little discomfort, but no pain. Dr. Lent is an outstanding orthopedic surgeon with excellent bedside manner. He always timely returns phone calls and takes the time to explain the proceedure and what to expect afterward. He has a caring and professional office staff and the physical therapists are outstanding as well. I highly recommend Dr. Lent!

partial knee replacement surgery

Dr. Spencer, Dr. Lent , Dr. Joseph and Dr. Edelson are GREAT! After my Partial replacement knee surgery, I was back to work in 2 1/2 weeks. After 1 month 1/2, I can tap dance. THAT'S GREAT!!!!

MAKO partial knee replacement

Friday surgery, Saturday climbing stairs, no pain no problem! Home Sunday. Did not need therapy, no limitations. I highly recommend Dr. Lent to fix your knee problems. I am better than ever, I even now go to the gym daily, something I had given up a long time ago. Truly amazing surgery by a truly amazing surgeon.


bilateral MAKO

Would just like to say that my experience was top notch. From the office staff, who were helpful above and beyond, to the Doctors and PA. Everyone is knowledgeable and thorough. I would recommend this practice to anyone looking to have any type of orthopedic treatment. Thanks again and again!!


Meniscus tear

Dr. Lent performed arthroscopic surgery to repair a torn meniscus in my right knee. From the time I first met with him, he was very professional and explained the necessary treatment in detail. He was extremely reassuring and made me feel confident in the procedure and full recovery. The surgery went very well, and my recovery has been even better than expected. I am immensely grateful to Dr. Lent, and would heartily recommend him.


knee surgery

I remember my brother in law went to Dr. Lent in 2001. He always seemed so happy with the repair to his ACL. So when I had the same injury, I also went to him and was just as pleased. The surgery and recovery was unbelievable. Thank You Dr.Lent.



I had makoplasty surgery with Dr. Spencer two years ago on my left knee and everything went well.I decided to do my right knee and to my amazement it has now been 6 weeks and everything is great. I already can bend my knee more than I have in many years. Dr. Spencer is a caring and attentive doctor and I would recommend him to anyone. He also has an excellent staff supporting him and anytime I had any questions or concerns they were always quick to answer my questions. He also has an excellent physical therapy department located in his office.


Ulnar Nerve Transpostion

Dr. Spencer did a awesome job on my arm I have now fully recovered. The whole process was very smooth with very little pain And almost no discomfort. The staff at both St. John's Riverside Hospital and Southern Westchester Orthopedic are wonderful.


ACL Reconstruction

Dr. Lent has an excellent bedside manner, taking the time to make sure I was fully informed every step of the way. He took the time to answer my questions so that I felt confident during and after surgery.


Partial knee replacement

On April 1, 2015 I underwent a partial knee replacement on my right knee. The following day I was released from the hospital and went home. Within one week I was up and about and almost back to normal. By Mother's Day I was off to Colorado to visit my daughter and in July I went off to Ireland with all of my family, my husband, my three children and their spouses and my five grandchildren. I felt like a brand new person. Thank God for caring and skilled doctors such as Dr. David Lent and all the members of Southern Westchester Orthopedics & Sports Medicine.


partial knee replacement

I am so very grateful to Dr.Lent! I had suffered far too many years, and underwent 2 knee surgeries elsewhere before finally taking the plunge. When I met Dr. Lent, he explained everything in great detail and was very professional. My end result says it all...I am back to my old self and doing all the things I was un too much pain to do before. Thank you so much to Dr. Lent for giving me my life back!!



I had makoplasty done to my knee and a few hours after getting out of recovery. I was walking laps around the hospital floor with my walker. I was in less pain after a week of recovery than before the surgery. I was back to work two weeks after surgery ,walking and doing all the things I did before. Dr Lent did a great job and my leg is now straight and I walk without pain and no more back pain also. His staff and Dobbs Ferry Hospital took care of everything I needed and after care and I had a great recovery. Thanks


right knee replacement

Feb 2 2016 I went in for a total right knee replacement. I was up and walking slowly the next day & was released the following day. Dr. Lent is a pleasure and a concerned Doctor The staff at Dobbs Ferry / St. Johns hospital are just fantastic , concerned about your comfort and pain management. If you need to have it done this is the Doctor & Place


2 patella femoral makoplasty surgeries

On 12/30/15 & 1/19/16 Dr. Lent and his team performed patella femoral makoplasty surgery on my knees. Though the recovery journey was a long one for me due to other issues I had, I can safely say that I am a card carrying member of Dr. Lent's cheer leading team! For the first time in YEARS I can walk without pain!!!! I really am a new woman. Thank you so much! But seriously, if you are as plagued by serious osteoarthritis as I was, DO NOT delay in getting it treated, as it will worsen with time. Please make an appointment as this is the place to go if you want your life back!!!


right total hip replacement

I had a right total hip replacement on March 29th....4 months later I have my life back...pain free. I can dance, exercise, walk miles, walk in the sand. Dr.Lent is an incredible Surgeon. I had a speedy, uneventful recovery. The care and attention that me and my family received at the Westchester Orthopedic Center was far better than the care and outcome I received for my left a prominent surgical center in Manhatten.


ACL Repair

On August 29th, 2016 I tore my ACL in my left knee. I was referred to Dr. Lent by a retired nurse who stated that "Dr. Lent will make you whole again, for sure." And boy, was she not kidding. After the MRI of my knee I waited about a week for the results. Being an athlete my entire life and never sustaining a knee injury of any kind I was certain that it was just a bad sprain. When I visited Dr. Lent for the 1st time, he very kindly and graciously informed me that my ACL was indeed, "completely torn." I panicked and entered into a state of shock and dismay. Dr. Lent's calm, jovial, humane demeanor kept me calm and mentally stable. I KNEW he was THE BEST because initially he did not want to perform the surgery on my knee due to my age-- he suggested "3 months of therapy, first" and told me that if what happened to me had happened to HIM, that he "would not opt for the surgery at first." Because my knee was literally "buckling apart" at this point and I could not fathom the thought of never body-boarding, motorcycling, hiking, swimming, jet-skiing, running or even walking again, I opted for the surgery, which was performed by the great Dr. Lent on September 23rd. The procedure was ambulatory and arthroscopic in nature and I was out of the hospital in a few hours. Today is December 1st and I have 85% mobility in my left knee, can walk up and down the stairs without pain or struggle and can even throw a front-kick with ease. Thanks to Dr. Lent and his amazing, in-house physical therapist, Mr. Patrick Evia I am practically back to my former self only better, stronger and soon to be, faster. *IF ANYONE READING THIS REQUIRES ANY KIND OF KNEE, LIGAMENT, TENDON, NECK or BACK SURGERY, THERAPY or even just a CONSULTATION, SEEK NO FURTHER AND REST EASY - DR. LENT WILL HEAL YOU AND MAKE YOUR LIFE EVEN BETTER THAN IT WAS BEFORE.


fractured wrist

The emergency room treatment at St. john's was quick, effective and very professionally provided. The medical treatment performed in the following days by Dr. Eric Spencer, including surgical insertion of support pins, was very helpful. Despite the damage to my wrist bones, I had little follow-up pain, was instructed in the best care including PT, and my wrist has recuperated quickly, much sooner than I would have predicted. Five stars!



Dr. Lent recommended a makoplasty for my right knee . He said it was a wonderful procedure and was virtually made for my situation . He was correct . I have no pain and can walk "forever". I'm very satisfied and would recommend this procedure highly . Dr. Lent is a very reassuring doctor . I highly recommend him and this procedure .


straightened fingers

I had a condition where I could not straighten my fingers. Shaking hands or trying to retrieve anything from my pocket was impossible. The condition is know as Dupuytren's Contracture. It use to require surgery. In two office visits, Dr Spencer did a minor procedure which cured my situation. I was able to shake his hand and say thank you.

Total Hip Replacement

I would like to thank Dr. Lent, Dr. Spencer and the Staff of Westchester Orthopedics. I recently had a Total Hip Replacement, and I am amazed at how quickly I am recovering. For 6 months prior to surgery, I was in agonizing pain...nothing helped, not pain pills, not pain management. My quality of life was quickly diminishing, and I am only 51 years old. I was constantly cancelling family plans, and had a hard time making it into work every day. I couldn't sleep; I would just pace the night away, praying for some relief somehow. It has only been about 11 weeks since surgery, and I am a new person! I received the best care at the hospital. The wonderful staff at St. John's in Dobbs Ferry got me up on the same day I had surgery! I had therapy at home for a couple of weeks, and continued physical therapy in office for a few more. I have already been able to increase my walking to 2 miles a day! I cannot thank Drs. Lent and Spencer enough for giving me back my life!


knee replacment

As a heavy duty bus mechanic I do a lot of bending kneeling and squatting at work . 5 months to the day of surgery I was able to return to full duty at work with a brand new knee . at 60 years old I thought I would have to retire but Dr Lent has given me a new lease on life . I no longer wake up at night due to the pain in my knee and no loner take daily med's for pain.
