Patellofemoral Realignment
What is patellofemoral misalignment?
The knee joint is formed by the junction of the patella (kneecap), the femur (thigh bone), and the tibia (shin bone). The patella is secured to the front of the knee by the quadriceps tendon, which connects to the femur, and the patellar tendon, which attaches to the tibial tubercle. As the knee flexes and extends, the patella glides along the trochlear groove at the distal end of the femur.
Patellofemoral malalignment is a condition where various factors cause the patella to shift out of place, damaging the soft tissues beneath the kneecap. These factors include:
- Shallow Trochlear Groove (Trochlear Dysplasia): If the groove is naturally shallow, the patella can slide out of place even with minor trauma.
- Malalignment of the Tibial Tubercle: If the attachment point of the patellar tendon is not properly aligned, recurrent patellar dislocations or subluxations can occur.
- Congenital Abnormalities: Conditions such as a high-riding kneecap (patella alta), flat feet, or anatomical defects of the kneecap increase the risk.
- Muscle Weakness: If the quadriceps muscle or tendon is weak, the patella cannot track smoothly within the groove.
How is patellar-femur misalignment treated?
In cases resulting from muscle or tendon weakness, conservative treatments can alleviate symptoms. Physical therapy programs aimed at strengthening the quadriceps muscles are particularly recommended.
However, for patients with a history of recurrent patellar dislocation, surgical intervention usually yields the best results. Serkan Sürücü treats patients with patellofemoral misalignment surgically.
How is patellofemoral realignment surgery performed?
The surgical approach is chosen based on the patient’s specific condition and must be performed by an experienced orthopedic surgeon. The techniques used by Dr. Serkan Sürücü include:
- Arthroscopic Examination and Repair: Using a minimally invasive method, a small camera is inserted into the knee joint. The bones, tendons, ligaments, and cartilage are systematically examined, and damaged tissues are removed using specialized instruments.
- Lateral Retinacular Release: The fibrous tissue on the outer side of the kneecap (lateral retinaculum) is loosened to allow the kneecap to shift back into its correct, centralized position.
- Tibial Tubercle Osteotomy (TTO): In cases of severe malalignment, the tibial tubercle (the bony bump on the shinbone) is surgically repositioned and secured with screws to improve the tracking of the patellar tendon.
Post-operative Recovery Process
Recovery time varies between 3 to 12 months depending on the specific surgical method performed. Generally, the timeline follows these phases:
- Initial Weeks: Limited weight-bearing using crutches is required to protect the surgical site.
- Early Recovery: Strenuous activities must be avoided for the first few months, with physical demands increased gradually thereafter.
- The Key to Success: Active participation in and completion of the personalized physical therapy program designed by Dr. Serkan Sürücü. This program is crucial for restoring knee function, improving range of motion, and strengthening the quadriceps muscle.
Purpose of the Procedure and Indications
Patellofemoral Realignment is not planned simply to correct a scan finding. Candidacy brings together pain, loss of function, the structural problem, the quality and duration of appropriate non-surgical care, and the patient's work or sporting goals. The expected benefit and limitations are defined before surgery so that the operation addresses a clinically meaningful problem.
Who Is a Candidate and When Is Surgery Deferred?
The diagnosis should be supported by examination and imaging, and expected benefit should outweigh risk. Active infection, uncontrolled medical disease, smoking that materially affects healing or an inability to participate in rehabilitation may need attention first. Age alone does not decide treatment; tissue quality, activity goals and overall health are considered together.
Preparing for Surgery
Medicines, blood thinners, allergies and previous operations are reviewed, and medication is not stopped without medical advice. Transport, help at home and early daily tasks are planned in advance. The consent discussion covers the proposed procedure, possible additional work, pain control, protection and rehabilitation so that recovery expectations are practical.
How Is the Technique Chosen?
Open or arthroscopic access, implant or graft choice and associated procedures are matched to the anatomy of the problem. Operations with the same name do not contain identical steps for every patient. Findings at surgery may require the plan to be adjusted within the alternatives discussed beforehand, particularly when tissue quality differs from imaging.
Anaesthesia and the First Days
Anaesthesia is selected for the extent of surgery and the patient's health; a regional block can support early pain control in some operations. Wound care, prescribed medicines, swelling control and sling or brace instructions matter during the first days. Permitted movement of the hand, foot or neighbouring joints helps maintain circulation and mobility without stressing the repair.
Risks, Alternatives and Review
Infection, bleeding, stiffness, nerve or vessel injury, persistent pain and failure to reach the intended result are general risks; procedure-specific risks are discussed separately. Alternatives may include activity changes, physiotherapy, medication or injections depending on the diagnosis. Increasing wound redness or drainage, fever, new numbness or weakness, or unexpected severe pain needs prompt review. The next step should reflect the diagnosis, the demands placed on the joint and the patient's goals. You can review knee care, read about knee arthroscopy, or request an assessment for an individual plan.
Shared decision-making is important because the same anatomical finding can affect two people differently. Work demands, caregiving responsibilities, sport, previous treatment and tolerance for recovery time all influence the choice between continued rehabilitation, an injection or an operation. The plan should state what success means and when it will be reconsidered.
A useful treatment plan for Patellofemoral Realignment records a baseline before intervention: pain-provoking tasks, active movement, strength or endurance and the activities the patient wants to regain. Repeating the same measures at follow-up shows whether progress is meaningful and helps distinguish a temporary reduction in pain from a durable improvement in function.
Continue with knee care, knee arthroscopy and knee osteoarthritis treatment, or use contact and appointments for an individual assessment.
