- Preoperative Diagnosis: Torn medial meniscus, left knee Postoperative Diagnosis: Combination horizontal cleavage tear/flap tear, posterior horn, medial meniscus, left knee. Operation: Arthroscopic subtotal medial meniscectomy, left knee Anesthetic: General endotracheal Description of Procedure: The patient was placed on the operating table in the supine position and general endotracheal anesthesia was administered. After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites. These stab wounds were made anterolaterally at the level of the superior pole of the patella for insertion of an irrigation catheter into the suprapatellar pouch area, anterolaterally at the level of the joint line for insertion of the scope and anteromedially at…arrow_forwardUARDIAN SIGNA Life Sciences/ Baseline Test Grade 10 ry must be written in point form. pot in full sentences using NO MORE than 70 words sentences from 1 to 7. only ONE point per sentence. words as far as possible. number of words you have used in brackets at the end GDE/2024 QUESTION 3 The table below shows the results of an investigation in which the effect of temperature and light on the yield of tomatoes in two greenhouses on a farm was investigated.
