Name of the Procedure:

Reconstruction of Dislocating Patella (e.g., Hauser Type Procedure)

Summary

The Hauser type procedure is a surgical intervention designed to stabilize a dislocating kneecap (patella). It involves adjusting the alignment of the soft tissues and bones to prevent the patella from shifting out of position.

Purpose

This procedure addresses recurrent patellar dislocation, a condition where the kneecap frequently slips out of its place. The goal is to stabilize the patella, reduce pain, improve knee function, and prevent further dislocations.

Indications

• Recurrent patellar dislocation
• Chronic knee instability
• Pain associated with a dislocating patella
• Failure of conservative treatments such as physical therapy and bracing

Preparation

• Fasting is generally required 8-12 hours before surgery.
• Medications may need to be adjusted as per the doctor's guidance.
• Diagnostic tests like X-rays or MRI scans may be performed to assess the knee's condition.

Procedure Description

1. Anesthesia: General or regional anesthesia is administered.
2. Incision: A surgical incision is made over the knee.
3. Realignment: The surgeon realigns the patellar tendon and may perform soft tissue adjustments or bone realignments.
4. Securing the Patella: Soft tissue is tightened, and potential osteotomies are done to ensure the patella remains in place.
5. Closure: The incision is closed with sutures or staples.

Tools involve surgical instruments like scalpels, retractors, and specialized orthopedic tools. Imaging devices may be used for precision.

Duration

The procedure typically takes 1-2 hours to complete.

Setting

It is performed in a hospital or surgical center in an operating room setting.

Personnel

• Orthopedic surgeon
• Anesthesiologist
• Surgical nurses
• Operating room technician

Risks and Complications

• Infection
• Bleeding
• Blood clots
• Stiffness or decreased mobility
• Recurrence of patellar dislocation
• Nerve or vascular damage

Benefits

The primary benefit is increased knee stability, reducing the likelihood of future dislocations. Patients can expect pain relief and improved knee function, often starting a few weeks post-surgery.

Recovery

• Patients may need to wear a knee brace and use crutches initially.
• Physical therapy usually begins within a week to restore movement and strength.
• Full recovery and return to sports can take 6 months to a year.
• Follow-up appointments are needed to monitor progress.

Alternatives

• Physical therapy to strengthen muscles around the knee
• Knee braces or taping
• Less invasive surgical options, depending on the severity
• Each alternative has varying effectiveness and suitability based on the individual’s condition.

Patient Experience

Patients may feel discomfort and pain initially, which is managed with pain medications. Swelling and bruising are common but subside with time. As healing progresses, patients will regain mobility and strength through guided rehabilitation. Comfort measures include ice packs and elevation of the leg post-surgery.
