When knee pain starts to limit your life, it’s more than just an inconvenience—it’s a call to action. Knee cap replacement is a surgical option that can restore function and relieve pain specifically in the kneecap area, offering hope to many who suffer from localized knee osteoarthritis. Let’s dive deep into what knee cap replacement entails, who it’s for, and what you can expect from the procedure and recovery.
What Is Knee Cap Replacement?
Knee cap replacement, also known as patellofemoral replacement or patellofemoral arthroplasty, is a specialized form of partial knee replacement. Unlike total knee replacement, which resurfaces the entire knee joint, knee cap replacement focuses only on the patellofemoral compartment—the kneecap (patella) and the groove in the thigh bone (trochlea) where the kneecap rests.
This procedure resurfaces the damaged bone and cartilage of the kneecap and the adjacent groove with metal and plastic components. The goal? To relieve pain caused by osteoarthritis that is limited to this specific area, while preserving the rest of the knee’s healthy structures.
Why Consider Knee Cap Replacement?
If you’re struggling with knee pain that’s isolated to the front of your knee, and non-surgical treatments like medication, physical therapy, or injections no longer provide relief, knee cap replacement might be the answer. This surgery is ideal for patients whose cartilage damage is confined to the kneecap and its groove, making it a less invasive alternative to total knee replacement.
The benefits include:
- Smaller incision and less tissue disruption
- Faster recovery compared to total knee replacement
- Preservation of healthy knee compartments
- Improved knee function and pain relief
What Happens During Knee Cap Replacement Surgery?
The surgery typically lasts about 1 to 2 hours and starts with anesthesia—either general (you’re asleep) or regional (numb from the waist down). Here’s the step-by-step process:
1. Incision and Exposure
The surgeon makes a small incision (around 8-10 cm) at the front of the knee to access the patellofemoral joint. Soft tissues are carefully moved aside to avoid unnecessary damage.
2. Removal of Damaged Tissue
Only the worn or damaged cartilage and a small amount of bone from the kneecap and the trochlear groove are removed. Healthy bone and cartilage are preserved as much as possible.
3. Implant Placement
A metal implant resurfaces the groove in the thigh bone, while a plastic component resurfaces the underside of the kneecap. These implants are fixed to the bone with special bone cement to ensure stability.
4. Closure and Recovery
The surgeon closes the incision with stitches or clips. Post-surgery, you’ll be monitored as anesthesia wears off, and pain management will be initiated.
Post-Operative Care and Recovery
Recovery from knee cap replacement is generally quicker than total knee replacement. You’ll likely be encouraged to put weight on your knee soon after surgery, often with the help of a walking aid. Physical therapy plays a crucial role in regaining strength and motion. Pain is expected but manageable with prescribed medications.
Most patients experience significant pain relief and improved knee function within weeks, though full recovery can take a few months.
Is Knee Cap Replacement Right for You?
Deciding on knee cap replacement should be a collaborative process involving you, your family, your primary care physician, and an orthopedic surgeon. If your knee pain is localized to the kneecap area and other treatments have failed, this procedure offers a targeted solution that can get you back to your daily activities with less pain and better mobility.
