My interest in shoulder conditions includes arthroscopic rotator cuff, instability, labral, AC joint and cartilage repairs.

For the knee, my focus is on advanced cartilage repair including matrix-induced autologous chondrocyte implantation (MACI), osteochondral autograft and allograft reconstruction, anterior and posterior cruciate ligament (ACL/PCL) and other knee ligament reconstructions, meniscal repair and reconstruction, and patellofemoral joint problems such as instability and chondral defects, including osteotomies and medial patellofemoral ligament (MPFL) reconstructions.

For the hip, I specialize in arthroscopic treatment of labral tears and femoro-acetabular impingement (FAI) as well as hip tendon tears including endoscopic proximal hamstring and abductor tendon repairs.

For the ankle, my interests include the treatment of cartilage lesions, tendon injuries, and instability.

Non-surgical treatment methods that we utilize to treat these joints also include the use of ultrasound-guided joint injections, platelet-rich plasma (PRP) and stem cell injections.

My hobbies include striper and tuna fishing, snorkeling and playing sports with my three sons.

  • Dr. Czarnecki was one of the first surgeons in New England to perform ACL reconstructions using quadriceps tendon autograft
  • Dr. Czarnecki is one of a handful of surgeons in the US who performs endoscopic proximal hamstring repairs. This innovative technique reattaches torn hamstring tendons to the pelvis using three tiny incisions instead of a large 9" incision, causing much less pain with lower complication rate
  • Dr. Czarnecki continues to teach Orthopaedic Residents from the Harvard Combined Orthopaedic Program
  • Dr. Czarnecki serves as faculty for the Arthroscopy Association of North America teaching residents, fellows and practicing Orthopaedic Surgeons

Surgical Outcome System (SOS)

This Surgical Outcome study is an international study that Dr. Czarnecki asks you to participate in as a way for him to monitor patient outcomes for 2 years after your surgery. Traditional research takes years to provide information about best treatments and focuses upon X-rays and MRI’s. This study focuses upon you - the patient - and the impact of treatment upon your function. It allows for real-time review for sports medicine procedures, leading to more timely decision making about cutting edge treatments.

You will be asked to complete an online pre-surgery questionnaire.  You will then receive subsequent short surveys via email after your surgery with follow up questions about how you are doing.  In participating in this study, you will be helping Dr. Czarnecki to better understand how his patients perform after each surgery to better understand your overall improvement, pain management as well as long term functionality and satisfaction. It may seem overwhelming initially, but you can quickly get the hang of it, and we sincerely appreciate your participation! For more information, visit

In this video, Dr. Czarnecki demonstrates an anterior cruciate ligament (ACL) reconstruction using graft from the patient’s own quadriceps tendon. Using your own tissue (autograft) demonstrates a lower re-injury rate than using a cadaver graft (allograft.) This graft is a partial thickness graft so the architecture of the original quadriceps tendon remains intact. It also allows for a larger graft than hamstring tendons, and a thicker graft than the patellar tendon.

Dr. Czarnecki performs shoulder arthroscopic repair on an athlete with a significant injury after a shoulder dislocation that damaged the anterior and posterior labrum, also creating a cartilage injury on the glenoid socket as well as partial tear of the rotator cuff, and chronic bursitis.

Dr. Czarnecki performs knee arthroscopy on a 16-year-old female athlete for osteochondritis dissecans (OCD) of the medial femoral condyle (MFC) with internal fixation and bone grafting.

In this minimally invasive technique, Dr. Czarnecki repairs a chronic partial tear of the proximal hamstring tendon in a marathon runner. Rather than use an 8-10 inch open incision, three tiny portals are used to complete the repair. There is much less pain, and lower complications with this endoscopic repair technique that few surgeons perform.
