LOCATION: Outpatient, HospitalPATIENT: Beth MahoneyPRIMARY CARE PHYSICIAN: Ronald Green, MDSURGEON: Mohomad Almaz, MDPREOPERATIVE DIAGNOSES1. Chondromalacia, left knee.2. Torn left medial meniscus per MRI scan.POSTOPERATIVE DIAGNOSIS: Chondromalacia, left knee.PROCEDURES PERFORMED1. Examination, left knee, under anesthesia.2. Arthroscopy, left knee, with debridement of chondromalacia.ANESTHESIA: General with endotracheal intubation.FINDINGS: The patient was found to have significant chondromalacia in all three compartments. She had some bare bone on the femoral trochlear and significant fraying of the articular cartilage on the patella, as well as on the medial femoral condyle. The articular cartilage on the lateral femoral condyle was just frayed slightly, but no largeflaps of articular cartilage were raised. She did, however, have some flaps of articular cartilage raised on the floor of the lateral compartment. I could not find any specificmeniscal tears, but both medial and lateral menisci had fringe tags, which we removed. The anterior cruciate ligament was intact.PROCEDURE: Under general anesthesia the patient’s left knee was examined. She had no effusion. The collateral ligaments were intact. Lachman test was negative, aswas the pivot shift. McMurray test was negative. We then prepped the patient’s left leg with Betadine and draped it in a sterile fashion. An Esmarch bandage was used toexsanguinate the leg, and a tourniquet on the thigh was inflated to 300 mm Hg. The total tourniquet time was about 35 minutes. Three portals were used for this procedure. The first was placed along the superior anterolateral aspect of the knee, the second was placed along the inferior anterolateral aspect, and the third along the inferior anteromedial aspect of the knee. We distended the knee with lactated Ringer’s solution. We examined the suprapatellar pouch and the medial and lateral gutters. We immediately noted significant chondromalacia involving the patellofemoral joint. There were large flaps of articular cartilage hanging off the articular surface of the patella and actually an area of bare bone on the trochlea, which was close to the lateral femoral condyle. We used the shaver to trim the articular cartilage, which was hanging from the subchondral bone. We trimmed the leading edge of the fat pad slightly as well. I then examined the medial compartment and probed the medial meniscus. We could not identify a specific tear of the medial meniscus, although there were multiple fringe tags, which were removed with the shaver. She does have, however, significant chondromalacia involving the weight-bearing surface of the medial femoral condyle. There were flaps of articular cartilage that were loose and just laying on the subchondralsurface. We used the shaver to trim these loose bits of articular cartilage. We then examined the notch area and probed the anterior cruciate ligament. It was intact. We then examined the lateral compartment and probed the lateral meniscus. The lateral meniscus was intact, although there were several fringe tags, which were removed. She did have some raised flaps of articular cartilage on the lateral tibial plateau, and these were trimmed with the shaver. The articular cartilage in the lateral femoral condyle appeared to be in relatively good condition with only minor fraying. At this point, we thoroughly irrigated the knee and looked for any remaining loose fragments. We then drained the knee and injected 80 mg of Depo-Medrol with 2 cc of 1% Xylocaine. The hardware was removed and the skin incisions were closed using 4-0 nylon suture. Sterile dressings were applied under a 6-inch Ace wrap. She was then awakened and taken from the operating room in good condition, breathing spontaneously.FINAL SPONGE AND NEEDLE COUNT: Correct.MEDICATIONS: She was given IV Kefzol preoperatively, and she will be continued on Keflex for 5 days postoperatively as well. She will also be started on some aspirinpostoperatively. Pathology Report Later Indicated: Chondromalacia.Abstracting & Coding Questions:1. Was this a diagnostic or surgical arthroscopy?2. What is chondromalacia?3. Debridement of the chondromalacia is also referred to as4. Was the diagnosis for the meniscal tear reported?5. What CPT code(s) would be reported for this case?6.
