Knee Pathology

The fabella is a sesamoid bone that may contribute to the stabilization of the posterolateral knee corner and it can very occasionally act as a source of atypical and rare knee pain and functional impairment. Fracture of the fabella is a rare but important clinical entity which may be overlooked clinically and radiographically. However, it causes an intermittent mechanical pain of the knee and it can mistakenly harm another knee pathology like intra-articular loose body. We report a case of a 21-year-old man who was sustaining a fracture of fabella following vehicle accident.

Anterior Knee

AbstractInfrapatellar fat pad impingement represents a source of anterior knee pain that is often overlooked. Due to the scarcity of reports related to this disorder, we conducted a systematic review of the literature related to infrapatellar fat pad impingement in evaluating the following: (1) clinical presentation, (2) imaging, (3) management, and (4) clinical outcomes. A systematic review was conducted investigating all available primary literature related to the clinical presentation, imaging, management, and outcomes of infrapatellar fat pad impingement syndrome. A total of 15 studies (9 case reports, 1 case series, and 5 retrospective studies) comprising 167 patients met eligibility criteria for this review. Patients with infrapatellar fat pad impingement were found to most often present with anterior knee pain that worsened with activity, and was frequently associated with trauma. Anterior knee pain, tenderness to palpation over the patellar tendon, loss in terminal extension, and pain with direct pressure on the medial or lateral side of the patella with the knee extended was often found on examination. Although patients may have classic imaging findings on magnetic resonance imaging (localized edema of the infrapatellar fat pad, deep fluid-filled infrapatellar bursa, nonvisualization of clefts, fibrosis, and calcifications), not all patients had positive imaging findings, thus making infrapatellar fat pad impingement a clinical diagnosis. Treatment begins with nonoperative management, but in recalcitrant cases, patients can be surgically treated with arthroscopic fat pad resection. Most patients who undergo operative treatment report improvement or complete resolution of symptoms in terms of pain and range of motion, and are able to return to work. To the best of our knowledge, this is the first comprehensive review on infrapatellar fat pad impingement to better aid the orthopaedic surgeons in diagnosing, treating, and managing patient expectations for this often overlooked knee pathology.

Abstract Background The effect of knee osteoarthritis, which causes knee pain, on higher-level functional competence (HLFC) is not clear. Objective To clarify the effect of knee pain on HLFC in older people. Design Community-based prospective cohort study. Setting Kurabuchi town, Gumma prefecture, Japan. Subjects Community-dwelling individuals aged 65 and older. Methods A total of 808 residents participated to the baseline examinations. The frequency of knee pain, degree of pain and functional impairment resulting from the pain were asked at baseline (2005–2006) via a self-administered questionnaire in Japanese based on an English version of the Western Ontario and McMaster Universities Osteoarthritis Index. Information on HLFC at baseline and during home visits were collected annually until 2014 with the Tokyo Metropolitan Institute of Gerontology Index of Competence. The association between baseline knee pain and HLFC decline was assessed with a Cox proportional hazards model. Results Two factors, persistent knee pain and severe functional impairment caused by the pain, were significantly associated with future declines in total HLFC, with adjusted hazard ratios (95% confidence intervals) of 1.51 (1.08–2.11) and 1.49 (1.10–2.00). In analysis by subcategory, persistent knee pain had a significant adverse effect on participants’ intellectual and social activities, and that severe physical functional impairment also had a significant impact on social activities. Conclusions The clear association of the frequency of knee pain and resultant functional impairment with future HLFC decline indicates that collecting information about these factors may be useful in identifying older people at high risk of future HLFC decline.
