Background Radiographs are routinely used to evaluate patients postoperatively after total knee arthroplasty, but no evidence-based guidelines exist regarding their use. The purpose of this study is to quantify the use of radiographs within 2 years of primary total knee arthroplasty by one surgeon and to determine if routine studies in asymptomatic patients altered patient management. Methods Patients undergoing consecutive primary total knee arthroplasties between 2008 and 2010 were identified. Patients undergoing revision or additional simultaneous procedures or those with less than 6 months of radiographic follow-up were excluded. Operative and clinic notes, radiographs, and radiology reports were reviewed. Results A total of 263 patients were identified; each patient had an average of 13.5 ± 3.8 individual radiographs obtained in 6.5 ± 1.7 series. Twelve radiographic series were noted to have abnormal findings by either the attending surgeon or by radiology report. Three of these patients underwent reoperation directly related to the findings; 2 for deep infections and 1 for extensor mechanism disruption. All 3 patients had reported abnormal symptoms when their films were obtained. The remaining 9 abnormal radiographic findings included focal lucencies or osteolysis, asymmetric spacer wear, a healing stress fracture, an inferior patellar avulsion fracture, and heterotopic ossification. No patient had symptoms attributable to these findings when the radiographs were obtained, and in no case was the management altered based on these finding. Conclusion This study suggests that the observed frequency of routine postoperative radiographs in asymptomatic patients may not be necessary in the first 2 years after primary total knee arthroplasty.

Injuries and disorders of the patellofemoral joint in the adolescent athlete can encompass a wide spectrum of symptomatology and pathology. Anterior knee pain is a common presenting symptom in sports medicine clinics, and can have numerous underlying etiologies. This activity-related pain may be the manifestation of enthesopathy, tendinopathy, fat pad impingement, or numerous other conditions, but is more commonly related to more subtle skeletal and muscular imbalances. Treatment is typically nonoperative in nature, and excellent results are reported with physical therapy. Patellofemoral instability usually has a more dramatic onset in the form of dislocation or subluxation events, commonly experienced during athletics. Concomitant injuries to the patellofemoral articular cartilage are common. Again, treatment is typically nonoperative initially, but recurrent or recalcitrant instability may necessitate reconstructive or realignment procedures. Skeletal maturity often dictates what procedures can be safely attempted.

Occult intra-articular hip pathology is commonly found in patients with greater trochanteric pain syndrome, and may be a possible pain generator in patients with recalcitrant lateral hip pain. We investigated the effect of intra-articular hip injections in patients with recalcitrant lateral hip pain. Between September 2012 and May 2013, patients over the age of 18 with a history lateral hip pain who had received prior treatment with non-steroidal anti-inflammatory medications, physical therapy and peritrochanteric corticostroid injections were enrolled. Treatment consisted of an ultrasound guided intra-articular corticosteroid injection followed by a course of directed physical therapy and a non-steroidal anti-inflammatory medication. Patients performed GaitRite analysis at baseline and 12 weeks following the injection. In addition, the Modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Scores (HOS), Short Form 36 (SF-36) and a visual analogue pain score (VAS) were collected at baseline, 1, 6 and 12 weeks.A total of 16 patients were studied. Patients experienced significant improvements from their baseline mHHS at 1 and 12 weeks (P = 0.03, P = 0.04). The minimal clinically important difference (MCID) was exceeded at multiple timepoints on various clinical outcome surveys. Velocity and stride length were not significantly improved at 12 weeks. Intra-articular hip injections may decrease pain and improve function in patients with recalcitrant lateral hip pain, and occult intra-articular hip pathology should be considered in the etiology of lateral hip pain. Though low enrollment numbers left this study underpowered, MCID comparisons demonstrated potential benefit from this treatment.

We report a patient with cauda equina syndrome secondary to retained Surgicel (Ethicon: Johnson & Johnson Medical, Piscataway, NJ, USA) and Gelfoam (Pfizer, New York, NY, USA). Retained hemostatic agents such as these used in spinal surgery can create space occupying lesions that lead to neurological compromise. There are few reports of neurologic symptoms caused by hemostatic devices used in surgery despite their widespread use. Our patient had routine lumbar microdiscectomy with preexisting motor deficits, and the acute postoperative course was complicated by a decline in neurologic function. The findings at the time of reoperation confirmed compression due to Gelfoam and Surgicel in the spinal canal, and subjective and objective symptoms partially improved after reoperation.

We report a unique surgical treatment for external coxa saltans refractory to previous open and endoscopic management in a patient with Ehlers–Danlos syndrome. After failure of two endoscopic iliotibial band (ITB) lengthenings and one open gluteus maximus (GMax) lengthening, a novel procedure was conducted, which involved release of the GMax insertion and tenodesis of the anterior and posterior portions of the ITB to prevent pathologic translation over the trochanter.
