A sudden dislocation of the kneecap can be both painful and alarming, and it’s rarely something to “walk off.” At Sacramento Orthopedic Sports & Shoulder, Dr. Takenishi emphasizes that prompt evaluation and proper Patellar Instability Treatment are essential to prevent long-term knee issues. Without timely care, patients are at risk of recurrent dislocations, cartilage damage, and early-onset arthritis.
In this article, we’ll review how the knee works, what causes patellar instability, and the treatment options, both nonoperative and surgical, that help restore stability and prevent future problems.
Understanding the Anatomy Behind Patellar Instability
To understand the right Patellar Instability Treatment, it’s important to first look at how the knee normally functions.
The patella, or kneecap, glides up and down within a groove on the femur called the trochlear groove. It acts as a pulley, allowing the quadriceps muscles to straighten the leg efficiently. For smooth and stable motion, several structures must work in harmony, the bones, the cartilage, and the surrounding ligaments.
One of the most important stabilizers is the medial patellofemoral ligament (MPFL). This ligament keeps the kneecap from sliding too far outward. When a dislocation occurs, the MPFL is usually torn or stretched. Without repair or proper rehabilitation, that injury can lead to repeated instability episodes.
Anatomic Risk Factors
Some people are more prone to patellar instability because of their anatomy. Common contributing factors include:
- Shallow trochlear groove (trochlear dysplasia): The groove the patella rides in is too flat, allowing it to slip out more easily.
- Patella alta: The kneecap sits higher than normal, engaging the groove later in motion.
- Increased tibial tubercle–trochlear groove (TT-TG) distance: The patellar tendon attaches more laterally, pulling the patella outward.
- Ligamentous laxity: Naturally looser ligaments make it harder to maintain stability.
- Knee alignment issues: Knock-knees (valgus) or rotational differences in the leg bones can alter tracking forces.
Because each patient’s anatomy is unique, Dr. Takenishi performs a thorough evaluation at Sacramento Orthopedic Sports & Shoulder, often including MRI or CT imaging, before recommending a specific Patellar Instability Treatment plan.
Why You Should Seek Care Immediately After a Dislocation
If your kneecap pops out of place, even once, you should schedule an orthopedic evaluation right away. Delaying treatment increases the risk of long-term complications.
1. Detect Hidden Damage
A patellar dislocation can injure more than just the ligament. Cartilage can chip off, bones can bruise, and the joint surface can sustain microfractures. Imaging helps identify these issues early so they can be addressed properly.
2. Prevent Recurrent Dislocations
Once the MPFL is damaged, the knee is more vulnerable to future instability. Early Patellar Instability Treatment helps protect healing tissues and strengthens supporting muscles before the knee becomes unstable again.
3. Avoid Early Arthritis
Repeated patellar dislocations can wear down cartilage, increasing the likelihood of developing patellofemoral arthritis. Acting quickly can help protect the joint long-term.
4. Return to Activity Sooner
With prompt diagnosis and a tailored treatment plan from Dr. Takenishi, patients can often begin recovery sooner and return to sports or daily activities safely.
Nonoperative Patellar Instability Treatment
Not every case requires surgery. For a first-time dislocation without major cartilage injury or anatomical abnormalities, nonoperative Patellar Instability Treatment can be very effective.
Patellar Stabilization Brace
A specialized brace holds the patella in correct alignment, allowing tissues to heal while reducing the risk of another dislocation. It’s typically used during daily activities and rehabilitation exercises.
Physical Therapy
Rehabilitation focuses on strengthening the quadriceps, especially the vastus medialis oblique (VMO), which helps guide the patella’s motion and tracking normally in the knee. Therapy also includes core and hip strengthening, balance training, and gradual activity progression.
The goal is to retrain muscles to stabilize the knee naturally, reducing dependency on external support.
Activity Modification
Patients may need to temporarily avoid activities involving twisting, pivoting, or deep squatting until the knee has regained strength and control.
While nonoperative management can be successful, Dr. Takenishi cautions that recurrence rates after a first-time dislocation can range from 15% to 60%, depending on the individual’s anatomy. Follow-up monitoring is important, especially for young or athletic patients.
Surgical Options for Patellar Instability Treatment
For patients with recurrent dislocations, failed nonoperative care, or specific anatomic risk factors, surgery may be recommended. The goal of operative Patellar Instability Treatment is to restore stability, improve knee function, and prevent future cartilage damage.
MPFL Reconstruction
The medial patellofemoral ligament (MPFL) is reconstructed using a graft (often from the patient’s own hamstring tendon or a donor). The new ligament restores the patella’s normal restraint against lateral movement.
Dr. Takenishi performs MPFL reconstruction at Sacramento Orthopedic Sports & Shoulder using advanced techniques that prioritize proper graft placement and tensioning to ensure natural patellar tracking.
This procedure is often performed in isolation when the rest of the knee anatomy is favorable. Recovery typically involves wearing a brace, followed by progressive rehabilitation focusing on range of motion and muscle control.
Tibial Tubercle Osteotomy (TTO)
In cases where the patellar tendon pulls the kneecap too far laterally or where the kneecap sits too high (patella alta), Dr. Takenishi may recommend a tibial tubercle osteotomy. This procedure repositions the tendon attachment point to correct alignment and reduce lateral pull on the patella.
When combined with MPFL reconstruction, it can provide long-term stability for patients with more complex anatomic issues.
Choosing the Right Procedure
The exact surgical approach depends on each patient’s anatomy:
| Condition | Typical Procedure | Goal |
| Recurrent dislocation, normal anatomy | Isolated MPFL reconstruction | Restore soft tissue restraint |
| Elevated TT-TG or patella alta | MPFL reconstruction + TTO | Correct alignment and stabilize |
| Severe trochlear dysplasia | MPFL + TTO, possible trochleoplasty | Address bony and ligamentous factors |
By tailoring surgery to the individual, Sacramento Orthopedic Sports & Shoulder achieves strong, lasting outcomes for patients across Sacramento and Northern California.
Recovery and Rehabilitation
Recovery after surgical Patellar Instability Treatment is progressive and carefully structured:
- Initial phase (0–6 weeks):
The knee is protected in a brace, often locked in extension for walking. Gentle range-of-motion exercises begin under supervision. Protected weight bearing for 6 weeks. - Intermediate phase (6–12 weeks):
Gradual strengthening of the quadriceps, hamstrings, and hip stabilizers begins. Patients work on restoring balance and coordination. - Advanced rehabilitation (3–6 months):
Functional training, light jogging, and controlled agility exercises are introduced. - Return to sports (7-12 4–7 months):
Athletes gradually return to full activity once they regain strength, stability, and confidence in the knee.
Dr. Takenishi works closely with physical therapists to ensure that recovery stays on track and that each milestone is achieved safely.
Preventing Long-Term Complications
The ultimate goals of Patellar Instability Treatment are:
- Preventing future dislocations: A stable knee reduces the likelihood of repeated injury.
- Protecting cartilage health: Preventing recurrent instability helps slow or prevent arthritis.
- Restoring normal function: Patients regain confidence in everyday activities and sports.
- Improving quality of life: Fewer flare-ups, less pain, and greater mobility.
With modern techniques and personalized care, Dr. Takenishi has helped many patients return to active, pain-free lives following both nonoperative and surgical treatments.
When to See a Specialist

- Ongoing knee instability or “giving way”
- Recurrent dislocations or near-dislocations
- Pain around the kneecap during bending or squatting
- Previous surgery that hasn’t resolved instability
Early evaluation helps ensure the best possible outcomes and limits future joint damage.
