The patient was a 32-year-old male who sustained a noncontact left knee injury during a quick pivot on a planted left foot, while playing flag football. Radiographs of the left knee revealed findings consistent with a tibial spine avulsion fracture, while magnetic resonance imaging confirmed a medial tibial spine avulsion fracture. Bone marrow edema was noted in a pivot shift injury pattern involving the lateral femoral condyle and the lateral tibial plateau, and there was also a fracture of the posterior lateral tibial cortex at the site of the bone marrow edema. To determine the best course of treatment, a computed tomography scan was ordered to better visualize the extent of the avulsion fracture. The computed tomography scan demonstrated a comminuted fracture through the tibial spine.

STUDY DESIGN: Cross-sectional. OBJECTIVES: This study examined the baseline relationship of pain intensity, physical impairment, and pain-related fear to shoulder function. BACKGROUND: There is no consensus regarding the influence psychological variable have on function and recovery in individuals with shoulder pathologies. While pain-related fear has been shown to predict disability for patients with low-back and cervical pain, this relationship has not been consistently reported for patients with shoulder pain. METHODS AND MEASURES: One hundred forty-two subjects (78 male, 64 female; mean age, 41.4 years) with nonoperative unilateralshoulder disorders were identified from a clinical database of impairment and outcome measures.Demographic information, duration of symptoms, mechanism of injury, pain intensity, pain-related
fear, and range-of-motion (ROM) measures were collected. Self-report of function was measured with the Shoulder Pain and Disability Index (SPADI). Hierarchical regression analysis determinedthe proportions of explained variance in function. RESULTS: Demographic variables (durationof symptoms, sex, age, and mechanism of injury) collectively contributed approximately 9% (P = .003) of the variance in function scores. Average pain intensity and flexion ROM contributed an additional 22% (P<.001) of the variance, and Tampa Scale of Kinesiophobia (TSK-11) scores contributed an additional 3% (P<.001). In the final parsimonious model, presence of symptoms longer than 3 months (ß = .23, P = .003), pain intensity (ß = .25, P = .002), shoulder flexion ROM index (ß = –.35, P = .001), and kinesiophobia (ß = .17, P = .026) explained 33% of the variance in SPADI function score (P<.001). CONCLUSIONS: Presence of symptoms longer than 3 months, average pain intensity, flexion ROM index (strongest contributor in multivariate model), and fear-of-pain scores all contributed to baseline shoulder function. The immediate clinical relevance of these findings is unclear but they do provide direction for prospective studies. LEVEL OF EVIDENCE: Prognosis, level 2b.

STUDY DESIGN: Cross-sectional. OBJECTIVES: To measure fear of movement/reinjury levels and determine the association with function at different timeframes during anterior cruciate ligament (ACL) reconstruction rehabilitation. We hypothesized that fear of movement/reinjury would decrease during rehabilitation and be inversely related with function. BACKGROUND: Fear of movement/reinjury can prevent return to sports after ACL reconstruction, but it has not been studied during rehabilitation. METHODS AND MEASURES: Demographic data and responses on the shortened version of Tampa Scale for Kinesiophobia (TSK-11), 8-Item Short-Form Health Survey (SF-8), and International Knee Documentation Committee (IKDC) subjective form were extracted from a clinical database for 97 patients in the first year after ACL reconstruction. Three groups were formed: group 1, less than or equal to 90 days; group 2, 91 to 180 days; group 3: 181 to 372 days post-ACL reconstruction. Group differences in TSK-11 score, SF-8 bodily pain rating, and IKDC scores were determined. Hierarchical linear regression models were created for each group, with IKDC score as the dependent variable and demographic factors, SF-8 bodily pain rating, and TSK-11 score as independent variables. RESULTS: TSK-11 score was higher in group 1 than in group 3 (P < .05). Across the groups, SF-8 bodily pain rating decreased (P < .001) and IKDC score increased (P < .001). SF-8 bodily pain rating was a significant factor in the regression model for all groups, whereas TSK-11 score only contributed to the regression model in group 3 (partial correlation, -0.529). CONCLUSIONS: Pain was consistently associated with function across the timeframes studied. Fear of movement/reinjury levels appear to decrease during ACL reconstruction rehabilitation and are associated with function in the timeframe when patients return to sports. LEVEL OF EVIDENCE: Prognosis, level 4.
