Lateral Closing Wedge Distal Femoral Osteotomy is a surgical procedure used to treat certain knee conditions and deformities. It involves making a controlled cut in the thighbone (femur) to correct alignment issues and restore normal function.
This type of osteotomy is typically performed to address conditions such as varus knee deformity or genu varum, commonly known as “bow-leggedness.” In these cases, the lower leg or shinbone (tibia) is displaced inward, causing misalignment, pain, and difficulty with weight-bearing activities. Lateral Closing Wedge Distal Femoral Osteotomy can help realign the leg and alleviate these symptoms.
The procedure involves removing a small wedge-shaped piece of bone from the outside of the femur, near the knee joint. By removing this wedge and closing the gap, the surgeon can effectively shift the alignment of the leg, bringing the knee into a more neutral position. To ensure stability and proper healing, the bone is typically fixed in its new position using plates, screws, or other fixation devices.
Patients undergoing Lateral Closing Wedge Distal Femoral Osteotomy can expect a period of recovery and rehabilitation following the procedure. Physical therapy and exercises are usually prescribed to help regain strength, range of motion, and functionality of the knee joint. Pain medication and icing may also be recommended to manage post-operative discomfort and swelling.
Understanding Lateral Closing Wedge Distal Femoral Osteotomy
A lateral closing wedge distal femoral osteotomy is a surgical procedure used to correct misalignment and deformity in the lower extremity. It involves the removal of a wedge-shaped section of bone from the lateral side of the distal femur to allow for realignment and improved function of the knee joint.
When is a Lateral Closing Wedge Distal Femoral Osteotomy Necessary?
This procedure is typically performed in patients who have varus malalignment, a condition where the lower leg is angled inward towards the midline. Varus malalignment can lead to stress on the knee joint, causing pain and limited range of motion. Lateral closing wedge distal femoral osteotomy helps to correct this alignment issue and relieve symptoms.
This procedure is most often recommended for patients who have not responded well to conservative treatment options such as physical therapy and medication. It may also be considered for individuals who have degenerative or traumatic conditions affecting the knee joint.
The Procedure
The lateral closing wedge distal femoral osteotomy is performed under general anesthesia. The surgeon makes an incision along the outer side of the knee and carefully exposes the distal part of the femur. A specialized saw is used to create a precise bone cut in the shape of a wedge, removing a section of bone from the lateral side of the distal femur.
The remaining bone segments are then carefully realigned using instruments to ensure proper alignment and stability of the knee joint. The bone segments are secured in their new position using plates, screws, or other fixation devices. The incision is closed using sutures or staples.
Recovery
Following the surgery, patients are typically required to wear a knee brace or cast to immobilize the knee joint and promote proper healing. Physical therapy is an essential part of the recovery process and helps to regain strength, stability, and range of motion in the knee.
Full recovery from a lateral closing wedge distal femoral osteotomy can take several months. It is important for patients to follow the post-operative instructions provided by their surgeon to ensure optimal healing and minimize the risk of complications.

It is important for patients to consult with an orthopedic specialist to determine if a lateral closing wedge distal femoral osteotomy is the appropriate treatment option for their specific condition. The success of the procedure depends on various factors, including the severity of the misalignment and the overall health of the patient.
Definition and Purpose of the Procedure
Lateral closing wedge distal femoral osteotomy is a surgical procedure that involves cutting and reshaping the end of the femur bone in the thigh. The purpose of this procedure is to correct deformities or abnormalities in the alignment of the knee joint, specifically to correct varus deformities (bow-leggedness).
During a lateral closing wedge distal femoral osteotomy, a small wedge-shaped portion of bone is removed from the outside of the femur, which allows the surgeon to realign the bones and correct the angle of the knee joint. This procedure can be used to address various conditions, such as osteoarthritis, knee instability, and malalignment caused by a previous injury or growth abnormality.
The ultimate goal of a lateral closing wedge distal femoral osteotomy is to relieve pain, improve knee function, and restore proper alignment to the knee joint. By correcting the varus deformity, this procedure can help reduce stress on the knee joint, prevent further damage, and potentially delay or avoid the need for more invasive procedures like knee replacement surgery.
It is important to note that lateral closing wedge distal femoral osteotomy is a complex surgical procedure that requires expert skill and thorough evaluation of the patient’s condition. The decision to undergo this procedure should be made in consultation with a qualified orthopedic surgeon who will assess the patient’s specific needs and determine the most appropriate treatment plan.
The Benefits and Risks of Lateral Closing Wedge Distal Femoral Osteotomy
Lateral closing wedge distal femoral osteotomy is a surgical procedure that involves cutting and realigning the femur bone in the knee joint to correct alignment issues. This type of osteotomy is typically used to treat conditions such as knee osteoarthritis, genu valgum (knock-knees), and unilateral idiopathic arthritis.
The Benefits
Lateral closing wedge distal femoral osteotomy offers several benefits for patients with knee alignment issues. Some of these benefits include:
- Pain Relief: By correcting the alignment of the knee joint, this surgery can help alleviate pain and discomfort caused by conditions such as knee osteoarthritis.
- Improved Functionality: Restoring proper alignment can enhance the knee joint’s ability to function optimally, leading to improved range of motion and overall joint performance.
- Delay or Avoidance of Joint Replacement: In some cases, this type of osteotomy can delay or even prevent the need for a knee replacement surgery by addressing the underlying alignment issue.
The Risks
While lateral closing wedge distal femoral osteotomy can provide significant benefits, there are also associated risks. These risks vary depending on individual circumstances but may include:
- Infection: As with any surgical procedure, there is a risk of infection. Measures are taken to minimize this risk, but it cannot be completely eliminated.
- Blood Clots: Surgery involving the knee joint can increase the risk of blood clots. Medication and preventive measures are often used to minimize this risk.
- Nerve or Blood Vessel Damage: During the surgery, there is a possibility of nerve or blood vessel injury. However, with an experienced surgeon, this risk is minimal.
- Nonunion or Malunion: In some cases, the bone may not heal properly or may heal in an incorrect alignment. This can affect the overall success of the procedure and may require additional surgical intervention.
It is important for patients considering lateral closing wedge distal femoral osteotomy to discuss the potential benefits and risks with their surgeon. Each patient’s case is unique, and a thorough evaluation of their individual circumstances can help determine the appropriateness and potential success of this procedure.
Recovery and Rehabilitation After Lateral Closing Wedge Distal Femoral Osteotomy
Recovery and rehabilitation play a crucial role in the success of a lateral closing wedge distal femoral osteotomy procedure. Following the surgery, patients will need to follow a structured rehabilitation program to regain strength and function in the affected knee.
Initial Post-Surgery Phase
During the initial post-surgery phase, the patient will typically stay in the hospital for a few days to ensure proper pain management and monitoring of the surgical site. The leg might be placed in a brace or immobilizer to protect the knee and promote healing.
Physical therapy will begin shortly after the surgery, focusing on gentle range-of-motion exercises and muscle-strengthening activities. The therapist will also educate the patient on proper techniques for using crutches or a walker to assist with walking and weight-bearing.
Mid to Late Rehabilitation Phase
As the patient progresses in their recovery, the focus of physical therapy will shift towards improving strength, balance, and flexibility. The therapist will guide the patient through exercises targeting the quadriceps, hamstrings, and calf muscles to improve overall knee stability and function.
Low-impact activities such as swimming or stationary cycling may also be introduced to aid in cardiovascular fitness without placing excessive stress on the healing knee. The therapist will monitor the patient’s progress and make adjustments to the rehabilitation program as needed.
Return to Normal Activities
The duration of the rehabilitation process can vary depending on the individual patient and their specific condition. Typically, it takes several weeks to several months to regain full strength and function in the knee.
Once the patient has regained sufficient strength and range of motion, they may gradually return to normal activities, including sports and recreational exercises. It is important to follow the therapist’s guidance regarding the intensity and frequency of these activities to avoid reinjury.
Regular follow-up appointments with the surgeon and therapist will be necessary to monitor the progress and address any concerns. Patience and compliance with the rehabilitation program are essential for achieving the best possible outcome after a lateral closing wedge distal femoral osteotomy procedure.

How Lateral Closing Wedge Distal Femoral Osteotomy Compares to Other Procedures
Lateral Closing Wedge Distal Femoral Osteotomy is a surgical procedure used to correct varus alignment of the knee joint by removing a wedge-shaped piece of bone from the lateral aspect of the distal femur. This procedure aims to realign the knee joint and improve the weight-bearing axis, reducing pain and improving joint function.
This osteotomy technique has several advantages compared to other procedures:
- Conservative approach: Unlike total knee replacement surgery, lateral closing wedge distal femoral osteotomy is a more conservative approach. It preserves the patient’s natural joint and allows for the possibility of future joint replacement, if necessary.
- Younger patient populations: This procedure is commonly recommended for younger patients with isolated lateral compartment osteoarthritis or chronic ligamentous instability. It is a good alternative for those who want to maintain an active lifestyle and delay or avoid total knee replacement surgery.
- Improved knee alignment: Lateral closing wedge distal femoral osteotomy can significantly improve the mechanical axis of the leg by correcting varus alignment. This realignment helps distribute the weight-bearing forces more evenly across the knee joint, reducing pain and slowing down the progression of osteoarthritis.
- Preservation of joint stability: By preserving the patient’s natural joint, lateral closing wedge distal femoral osteotomy maintains joint stability and reduces the risk of complications associated with total knee replacement surgery, such as infection and implant failure.
However, it is important to note that lateral closing wedge distal femoral osteotomy may not be suitable for everyone. The decision to undergo this procedure should be made after careful consideration and consultation with a qualified orthopedic surgeon.
