Claim:
1. A patient-specific tibial pin guide for placement on a tibia during a joint arthroplasty procedure on a patient, comprising: a patient-specific inner surface having a first offset portion and a second offset portion, wherein the first offset portion is configured to be offset from and mimic a first bone surface, wherein the first offset portion of the patient-specific inner surface is shaped to form a gap to accommodate soft tissue overlying a proximal surface of the tibia of the patient, and wherein the second offset portion of the patient-specific inner surface is shaped to provide clearance for a patella tendon of the patient; a first patient-specific contact area formed on the patient-specific inner surface, wherein the first patient-specific contact area is configured for direct bone registration without intervening soft tissue; a second patient-specific contact area formed on the patient-specific inner surface, wherein the second patient-specific contact area is configured for direct bone registration without intervening soft tissue, wherein the second patient-specific contact area is non-contiguous with the first patient-specific contact area.
