MRI Findings of Bone Marrow Edema in a Division I NCAA Women’s Soccer Team During a Competitive Season

As sports technology has continued to develop, monitoring athlete workloads, performance, and recovery has demonstrated boundless benefits for athlete and team success. Specifically, technologies such as global positioning systems (GPS) and heart rate (HR) monitors have granted the opportunity to delve deeper into performance contributors, and how variations may exist based upon context. A team of NCAA Division I women’s soccer athletes were monitored during games throughout one competitive season. Individual athlete, positional groups, and team external and internal workloads were explored for differences based upon game location, opponent ranking, game result, and the final score differential. Game location and opponent ranking were found to have no effect on team-wide absolute or relative external workloads, whereas game result and score differential did. Internal workloads across the team tended to only vary by game half, independent of game context; however, the HR of defenders was determined to be higher during losses as compared to wins (p = 0.0256). Notably, the games that resulted in losses also represented the games with the fewest number of substitutions. These findings suggest high value in monitoring performance and workloads that are characteristic of varying, often multifaceted, contexts. It is hoped that this information can lead to more informed approaches to vital game-time and coaching decisions.

Marrow Edema

Background: MRI findings are used in several staging systems to help determine appropriate treatment. The purposes of this study were to evaluate longitudinal changes in MRI characteristics of osteochondral lesions of the talus (OLT) and to evaluate published staging systems in a cohort of nonoperatively treated patients. Methods: Twenty-nine patients were identified; MR images were reviewed for location, size, and interface signal of OLT as well as cysts, marrow edema and osteoarthritis. Lesions were classified as unchanged, progressed, or improved based on changes in size or interface signal. Each lesion was assigned a stage based on four different staging systems. Results: Of the 29 lesions, 13 progressed, seven improved, and nine were unchanged over an average followup of 13.7 months. In the 13 that progressed, marrow edema remained present in ten and developed in two. Four had persistent cysts and four developed new cysts. Two had progression of osteoarthritis and two developed it anew. In the seven that improved, six had some degree of marrow edema that persisted and one had a persistent cyst. Initial staging changed for at least one classification system in 16 (55%) of the 29 lesions at followup. Change in stage was primarily due to development (four of 16) or disappearance of cysts or progression of the lesion in the extent of bone marrow edema (five of 16). Conclusions: OLT did not invariably progress over the short-term without operative intervention. Because some cysts and bone marrow edema resolved on MRI, they may not be reliable signs of lesion severity nor show progression of degenerative changes. Since these findings determine the stage and severity of OLT in some staging systems, they may require reconsideration and adjustment of the current staging systems.

Category: Ankle Introduction/Purpose: Sinus tarsi pain is very common, however, etiology of this condition has not been well understood. The purpose of this study was to evaluate differences of MRI findings between persons with and without sinus tarsi pain and to investigate the relationships of sinus tarsi pain and accessory anterolateral talar facet (AALTF). Methods: We reviewed MR images of 120 ankles with sinus tarsi pain in 115 consecutively registered patients. And age- and sex-matched MR images of 120 ankles without pain were also reviewed. We compared the presence of AALTF, calcaneal cyst (CC), bone marrow edema (BME), sinus tarsi fat obliteration (STFO) at the Gissane angle, and coalition between persons with and without sinus tarsi pain. We also compared Gissane angle, talar infero-lateral surface angle (TILSA), and calcaneal cortical thickness (CCT). Of persons with sinus tarsi pain, we compared these parameters between persons with and without AALTF. Results: AALTF was present in 61 ankles (50.8%) with sinus tarsi pain and 34 ankles (28.3%) without sinus tarsi pain (P<0.001). BME (P=0.001) and STFO (P=0.009) were significantly more frequent in persons with sinus tarsi pain. Presences of CC (P=0.108) and coalition (P=0.605) were not different. The Gissane angle was significantly smaller in persons with sinus tarsi pain than in persons without sinus tarsi pain (P<0.001) and TILSA (P=0.032), and CCT (P<0.001) were significantly larger in persons without sinus tarsi pain (Table 1). Of persons with sinus tarsi pain, BME was significantly more frequent in persons with AALTF and TILSA (P=0.032) and CCT were significantly larger in persons with AALTF (Table 2). Conclusion: The MRI findings of patients with sinus tarsi pain showed higher prevalence of AALTF, BME, and STFO. The AALTF may be associated with the MRI findings of talar and calcaneal BME.
