Figure 3From: Post-traumatic glenohumeral cartilage lesions: a systematic review Pathomechanism leading to chronic post-traumatic GH cartilage defects. In case of chronic post-traumatic GH cartilage defects, the RC is injured first. This may result to instability and following impingement and to a malnourished cartilage. In addition, RC tears might be further promoted. In the final stages, this mechanism might lead to GH articular cartilage damage.Back to article page
