Figure 33.15 (A) Periosteal osteophytes

typically remain the same size or become

slightly larger over time after tibial

plateau leveling osteotomy (TPLO). This

patient with a complete CrCL tear had

mild osteophyte formation (∗∗∗)inthe

medial gutter at the time of TPLO. (B) The

osteophytes increased a little in size over

34 months. Joint capsule (JC), medial

femoral condyle (MFC).

Figure 33.16 Some degree of synovitis

was typically seen at follow-up

arthroscopy in patients after tibial plateau

leveling osteotomy. These patients had

mild (A) and moderate (B) synovitis,

although both patients were subclinical.

Figure 33.17 (A) A mid-body medial meniscal release (MR) is performed under arthroscopic observation. Follow-up
arthroscopic evaluation revealed inconsistent findings at the MR incision site. (B,C) The site of MR healed (∗∗∗) with a
smooth axial border in most patients. (D) The gap at the MR incision filled with irregular fibrous tissue (∗∗∗) or showed no
signs of healing in other patients (∗∗∗) (E). Interestingly, minimal signs of cartilage wear of the medial femoral condyle
(MFC) and tibial plateau (TP) were seen. The MR appears to remain functional despite variation in healing patterns.
Evidence of continued function of the MR includes the caudal position of the medial meniscus and the dramatic
reduction in prevalence of postliminary meniscal tears.
