骨科英文书籍精读（316）｜膝关节韧带损伤的治疗（4）
我们正在精读国外经典骨科书籍《Apley’s System of Orthopaedics and Fractures》，想要对于骨科英文形成系统认识，为以后无障碍阅读英文文献打下基础，请持续关注。
中国十大名师之一赖世雄老师说过，学习英语没有捷径，少就是多，快就是慢。不要以量取胜，把一个音标、一个单词、一段对话、一篇文章彻底搞透，慢慢积累，你会发现，你并不比每天走马观花的输入大量英文学的差。
Isolated lateral instability is uncommon and symptoms are rarely troublesome enough to warrant surgery. If operative reconstruction is attempted, it should follow the lines described earlier.
Isolated PCL insufficiency rarely causes loss of function. Conservative treatment (mainly quadriceps strengthening exercises) will usually suffice.
Isolated ACL insufficiency is uncommon and can usually be managed by physiotherapy. Splints or braces may be used to speed the return to weightbearing. Patients seeking to resume competitive sport may need something more; reconstructive surgery involves replacing the torn ACL with an autologous graft, usually a strip of patellar tendon with bone attachments at either end or with hamstring tendons.

百度翻译：
单纯PCL功能不全很少导致功能丧失。保守治疗（主要是股四头肌强化训练）通常就足够了。
孤立性前交叉韧带功能不全是罕见的，通常可以通过物理治疗。夹板或支撑可以用来加速负重的恢复。想要恢复竞技运动的患者可能需要更多的东西；重建手术包括用自体移植物替换撕裂的前交叉韧带，通常是一端带有骨附着物的髌腱条，或者用腘绳肌腱。
