#1
Sang-Jin Shin, Rag Gyu Kim, Yoon Sang Jeon, Tae Hun Kwon
BACKGROUND: Generally, a glenoid bone loss greater than 20% to 25% is considered critical for poor surgical outcomes after a soft tissue repair. However, recent studies have suggested that the critical value should be lower. PURPOSE: To determine the critical value of anterior glenoid bone loss that led to surgical failure in patients with anterior shoulder instability. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: The study included 169 patients with anterior glenoid erosion...

BACKGROUND: Age is commonly accepted as a negative prognostic factor in cartilage surgery, and cutoff values of 30 to 40 years have been previously suggested as treatment indication. However, the lower outcome scores documented in older patients do not take in consideration the decreasing requirements of an aging joint. PURPOSE: To analyze the real effect of age in terms of recovery with respect to the functional level expected for different age categories of patients treated for cartilage lesions...

PURPOSE: Ramp lesions are common in ACL deficient knees. Their diagnosis is difficult and, therefore, they may be underestimated. So far, no study analyzed their prevalence in a pediatric population. The diagnosis of these Ramp lesions is of major clinical relevance because of a frequent misestimating and technic difficulties. Ramp lesions might be associated with residual knee pain and instability after ACL reconstruction. The aim of this study was to evaluate the prevalence of ramp lesions explored through a systematic intercondylar and posteromedial arthroscopic approach during an ACL reconstruction in a pediatric and adolescent population...

BACKGROUND: Patients with groin, hip and pelvic pain but normal findings on MRI and minimal changes on x-ray can be a diagnostic problem. This paper looks at the arthroscopic findings of patients who have had hip pain and a positive response to an intra-articular anaesthetic but have non-contributory imaging. We hypothesized that standard MRI's were missing significant pathology and if there was a response to intra-articular local anaesthesia, pathology found during arthroscopy was likely...

Bridget Ellsworth, Atul F Kamath
Background. Pigmented villonodular synovitis (PVNS) is a rare benign tumor affecting large joints and prompts excision to prevent local destruction of the joint. The purpose of this case report is to describe two differing surgical approaches for management of PVNS of the hip in patients requiring concomitant treatment for additional hip pathology. Methods. This report discusses the presentation, clinical and radiographic findings, and operative management of two contrasting cases of PVNS of the hip. Case 1 describes a 31-year-old female with localized PVNS in addition to a labral tear treated with arthroscopic labral repair followed by tumor excision via a mini-open incision...

Treatment of painful internal snapping hip via arthroscopic release of the iliopsoas tendon is becoming the preferred option over open techniques because of the benefits of minimal dissection and fewer complications. However, complications do occur with arthroscopic techniques as well. We present the case of a 33-year-old woman who presented with painful internal snapping of her right hip and underwent arthroscopic release of the iliopsoas tendon. Following the procedure she continued to complain of pain in her groin and was therefore investigated further with a magnetic resonance imaging (MRI) which revealed a swelling near the femoral circumflex vessels...
