Summary
Sulcus-deepening trochleoplasty effectively treats trochlear dysplasia, offering improved patellar stability and high patient satisfaction. This surgical technique is a viable option for patients unresponsive to conservative treatments.
Area of Science:
- Orthopedic Surgery
- Biomechanical Engineering
Background:
- Trochlear dysplasia is a common cause of anterior knee pain and patellar instability.
- Conservative management including bracing and physical therapy may fail in some patients.
- Surgical intervention like trochleoplasty is considered for refractory cases.
Purpose of the Study:
- To describe the indications and technique of sulcus-deepening trochleoplasty.
- To evaluate the outcomes and patient satisfaction following this procedure.
Main Methods:
- Review of 21 studies and one prospective study with minimum 2-year follow-up.
- Description of the thick shell sulcus-deepening trochleoplasty technique, including supratrochlear spur removal and creation of a new trochlear groove.
Main Results:
- Postoperative dislocation rates ranged from 0% to 15% across studies.
- Patient satisfaction was high, ranging from 81.0% to 94.4%.
- A prospective study reported no recurrent dislocations, no arthritis progression, and 84.8% return to sport.
Conclusions:
- Sulcus-deepening trochleoplasty is an effective surgical option for trochlear dysplasia.
- The procedure provides significant improvements in patellar stability and patient-reported outcomes.
