Subscapularis Deficiency

Rupture of the subscapularis after an anterior open instability repair causes significant functional disability, which may or may not be associated with recurrence of instability.

Often such tears go unrecognized when patients present postoperatively with weakness and pain but no clear evidence of recurrent instability. A high index of suspicion and a careful physical examination […]

Complications and Pitfalls-Recurrence

Recurrence is the most frequently reported complication after open and arthroscopic surgery for anterior instability. Recurrence may be secondary to new trauma or to atraumatic events.Patients with traumatic recurrence of their instability usually have better post-operative results after revision surgery than patients with atraumatic recurrence. The recurrence rate is related to the number of prior […]

Techniques-Glenoid Bone Deficiency

Although osteoarticular pathology rarely is a cause of anterior instability, it is essential that it be ruled out prior to proceeding with any soft-tissue stabilization procedure or in the revision setting. A small subset of patients may be predisposed to instability due to developmental glenoid dysplasia, or pathologic flattening or hypoconcavity of the glenoid as […]

Open Surgery

Open surgery for instability remains an acceptable method of treatment when the surgeon lacks the equipment, experience, or technical expertise to perform an arthroscopic repair. Furthermore, open surgery is indicated in situations where current arthroscopic methods are likely to fail—namely, in the setting of large bone or soft tissue deficiencies or in the context of […]

Patellar Instability or Mal – Tracking

SYMPTOMS

The knee feels unstable or weak, or gives way in association with recurrent pain around the anterior part of the knee, with or without preceding trauma. It is particularly common in young female athletes.

AETIOLOGY

This condition can be caused by inherited conditions such as patella baja or alta, genu valgus or […]

Lateral Ankle Ligament Ruptures

SYMPTOMS

The patient refers to a sudden sharp tearing pain around the lateral aspect of the ankle joint after an acute inversion sprain or, on occasions, of recurrent instability after previous sprains.

AETIOLOGY

The anterior talo-fibular (ATF) and fibulo-calcanear (FC) ligaments are the most commonly damaged structures in uncomplicated inversion-plantar flexion ankle sprain. Most […]
