Isolated partial tear of the anterior cruciate ligament should be suspected in the patient with effusion, flexion contracture and poorly localized pain and tenderness following a knee injury. The diagnosis is difficult to make from physical findings or even arthrography. Arthroscopy is helpful in making the diagnosis and in ruling out associated meniscus lesions. A normal meniscus should not be removed if this seemingly trivial lesion is the only abnormal finding at arthrotomy. Surgical treatment is not necessary if the diagnosis can be made by other means. This injury responds well to immobilization in extension followed by rehabilitation.
膝关节损伤后出现积液、屈曲挛缩以及疼痛和压痛部位不明确的患者，应怀疑存在孤立性前交叉韧带部分撕裂。仅通过体格检查甚至关节造影很难做出诊断。关节镜检查有助于诊断并排除相关的半月板损伤。如果在关节切开术中这一看似微不足道的损伤是唯一的异常发现，不应切除正常的半月板。如果能通过其他方法做出诊断，则无需手术治疗。这种损伤通过伸直位固定然后进行康复治疗，效果良好。
